Press Brake, as one of the key equipment in the sheet metal processing industry, although they play an important role in production, workers also have certain potential risks during operation, and factories also attach great importance to the safety of employees. In this article, we will explore the types of accidents that may occur in bending machines. As a professional bending machine manufacturer, ZYCO will propose corresponding preventive measures so that all users can clearly understand the machine and improve safety before using ZYCO machines.

 

Bending machines have the following types of accidents

1. Hand pressure accident

Hand pressure accident is one of the most common safety hazards in bending machine operation. During operation, if the operator's hand or other body parts accidentally enter the bending area, there will be certain disability accidents.

2. Drop accident

The operator may frequently change the mold. During this period, if the mold is not fixed well, it will be easy to cause the mold to fall and hit the machine, which will not only injure the operator, but also damage the machine.

3. Equipment failure

If the equipment failure is not promptly checked and maintained, it will also cause injuries and major damage to the machine.

4. Electric shock accidents

If the Press Brake has been used for many years without maintaining the electrical system, electric shock accidents such as leakage may occur.

5. Operational errors

For CNC bending machines, if the operator does not understand the use of the machine system, the machine may fail due to misoperation, resulting in dangerous accidents.

 

The occurrence of bending machine accidents is usually related to the following factors:

1. The staff does not know how to operate the machine: Many bending machine accidents are related to the operator's lack of understanding and skills of the machine.

2. Safety protection measures are not in place: If there are no certain safety production protection measures, the risk of bending machine accidents will increase.

3. Improper equipment maintenance: Lack of regular equipment inspection and maintenance may lead to equipment failure.

4. Poor working environment: The messy and unsafe environment in the workplace will increase the probability of accidents.

 

Preventive measures

1. Sheet metal factories strengthen the training of sheet metal bending workers

We can regularly provide operators with safety awareness and training on bending machine operation to ensure that they are familiar with the operating procedures and safety precautions of the bending machine.

2. Improve safety protection

The machine can be equipped with a laser protection device, which will greatly increase the safe working environment of the bending machine operator.

3. Regularly maintain the equipment

ZYCO recommends that all sheet metal factories establish a regular inspection and maintenance system for equipment. At the same time, ZYCO will also provide assistance to all users to ensure that the bending machine is in good working condition and eliminate potential fault hazards in time.

4. Improve the bending working environment

The workplace needs to be kept clean at all times, and workers should regularly clear obstacles around the bending machine to ensure the safety of the operating area.

 

Conclusion

Press Brake play an important role in metal processing, but the safety hazards in their operation cannot be ignored. ZYCO recommends that all users can effectively reduce the probability of accidents by understanding the types of accidents that may occur in bending machines and their causes, and taking corresponding preventive measures. In the future, with the development of technology and the improvement of safety awareness, the safe operation of ZYCO bending machines will continue to improve, providing safer protection for industrial production. We firmly believe that ZYCO will aim to produce the safest Press Brake and ensure that every machine we produce is the best and safe

Aluminum can recycling line generally consists of pre-shredder, shredder, hammer mill, magnetic separator, eddy current, middle feeding, decoating furnace, dust removal system.

 

If the raw material is mixed metal bale, first put the bale into pre-shredder for preliminary shredding; then convey the scrap metal to shredder through conveyor belt for further shredding. This can effectively protect the shredder blade. The scrap processed by shredder will be conveyed to hammer mill by conveyor belt. In hammer mill, the scrap will be processed into small pieces for later decoating. The magnetic separator will remove the iron impurities in the scrap by magnetic force. Then it will be conveyed to eddy current through conveyor belt. The eddy current separator will magnetize the scrap by electromagnetic induction principle. The eddy current itself will generate a magnetic field opposite to the original magnetic field, thereby ejecting the required scrap material and separating it from other non-conductive or weakly conductive materials. The final aluminum metal will go through the middle feeding, which can ensure that the material is uniform and continuously enters the decoating furnace for decoating treatment. The decoating furnace will be connected to the dust removal system for dust removal to solve the environmental protection problem of the operating environment.

Evaporators are essential components in many heat exchange systems, and spiral baffles play a unique role in allowing small evaporators to manage large heat loads effectively. By optimizing fluid flow and enhancing heat transfer, spiral baffles contribute to making even compact evaporators highly efficient.

What Are Spiral Baffles and How Do They Work?

Spiral baffles are specifically designed elements that create specialized flow paths inside the evaporator. When fluid enters the evaporator, the spiral baffle redirects it into a spiral flow pattern. Unlike traditional straight-line flow, the spiral path increases the turbulence of the fluid. This enhanced turbulence promotes better mixing of the hot and cold fluids, improving heat exchange efficiency. It’s similar to stirring coffee to dissolve sugar more quickly—better mixing leads to faster and more efficient heat transfer.

Why Does This Spiral Flow Improve Heat Transfer?

The spiral baffle design significantly extends the fluid’s path within the evaporator. In a small evaporator, this longer flow path ensures that the fluid has more contact time with the heat transfer surface. The increased contact time and surface area enhance heat transfer, allowing for more effective energy exchange between fluids. The longer flow path essentially “packs” more heat transfer into a smaller space.

Optimizing Flow Distribution for Maximum Efficiency

In addition to improving heat transfer through longer contact times, the spiral baffle helps optimize the flow distribution within the evaporator. In traditional evaporators, some areas may suffer from slow-moving or stagnant fluid, leading to inefficient heat exchange. Spiral baffles eliminate these dead zones by ensuring a uniform flow throughout the evaporator, allowing every part of the system to actively contribute to heat transfer.

The Impact on Performance

By modifying the fluid’s flow state, extending the flow path, and improving flow distribution, spiral baffles enable small evaporators to handle large heat loads. This design enhancement is invaluable in industries such as refrigeration and HVAC, where compact systems are required to operate at high efficiency despite their small size.

Key Benefits of Spiral Baffles in Evaporators

• Enhanced Heat Transfer:

The spiral flow increases turbulence, which promotes more efficient mixing and heat transfer.

• Compact Design:

Spiral baffles allow for greater heat exchange in smaller evaporators, saving space without sacrificing performance.

• Uniform Flow Distribution:

They reduce dead zones, ensuring that all parts of the evaporator contribute to heat exchange.

• Energy Efficiency:

The improved heat transfer reduces the need for large, energy-consuming systems, lowering overall operating costs.

• Adaptability:

Spiral baffles are suitable for a wide range of industrial applications, from refrigeration to air conditioning.

1.As the temperature gradually drops in winter, some customers have experienced poor adhesion, brittle hot melt adhesive, and degumming when using hot melt adhesive for production. What is the reason?

Hot melt adhesive is sensitive to ambient temperature. Due to the cold temperatures in winter, the hot melt adhesive bonding process is cold, resulting in rapid solidification and hardening. Some glue manufacturers will adjust the high-temperature and low-temperature resistance of the glue according to the season when producing glue. Please consult the glue manufacturer when using glue.

2.What is the difference between hot melt glue in winter and summer and autumn?

To be precise, there are some differences in the design of certain properties of glue between winter and summer. For example: the curing time (also called open time) of hot melt adhesive is an important factor affecting the viscosity of hot melt adhesive. Due to factory operations, they are basically carried out at room temperature. The room temperature in winter and summer is very different, so the curing time requirements for hot melt adhesive are different at this time. The same glue needs to shorten its curing time in summer and extend its opening time in winter.

3.What precautions should be taken when using a hot melt adhesive machine in winter?

1. During the bonding process, the hot melt adhesive is heated for too short a time, causing the temperature of the hot melt adhesive to fail to meet the requirements. When using hot melt adhesive in winter, please increase the operating temperature in the hot melt adhesive tank of the hot melt adhesive machine by 10~20°C. Frequently check whether there is any difference between the actual temperature in the glue tank and the table temperature to prevent the temperature control system of the machine from malfunctioning in winter and causing the meter temperature to be inconsistent with the actual temperature.

2. The setting temperature of hot melt adhesive is too low. If the temperature of the bonded material is lower than 15 degrees, it is recommended that qualified customers preheat the bonded material before packaging operation. If necessary, please add auxiliary heating facilities such as hair dryers, heating lamps, etc. to increase the temperature. their temperature to achieve good gluing effect. To ensure the quality of packaging.

3. The storage temperature is above 15℃. The temperature of the warehouse where hot melt adhesive is stored is also best kept above 15 degrees to shorten the melting time of hot melt adhesive.

4. The temperature during work or at the construction site is too low. Please pay attention to the insulation of the production workshop and avoid placing machines that use hot melt glue in places where air circulates quickly, such as doorways, vents, etc.

5. The substrate temperature is too low. Please pay attention to the insulation of the bonded materials. If materials stored in a low-temperature environment are used directly for packaging, the temperature of the glue will drop too quickly, adversely affecting the packaging effect, and in severe cases, the glue may open.

PUR hot melt adhesive (Polyurethane Reactive) is a new type of one-component, solvent-free hot-melt structural adhesive. It is cured by moisture in the air and has excellent bonding strength and impact resistance after complete curing. It also has With excellent bonding strength, temperature resistance, chemical corrosion resistance and aging resistance, it has become the best adhesive for bonding in electronic industries such as mobile phones in recent years.

Factors and solutions that affect the production process during the gluing process of the product:

1. Influence of chemical composition of PUR hot melt adhesive

The amount of certain chemical components of PUR hot melt adhesive directly affects the viscosity of PUR. From the perspective of product performance, we must choose a suitable glue.

2. The influence of different bonding materials

PUR hot melt adhesive has good bonding ability to different base materials, such as rubber, plastic, glass, metal, leather, wood, fabric, etc. For different bonding materials, choose the appropriate glue model.

3. The amount of glue applied

The amount of PUR adhesive layer applied will affect the curing time. If the adhesive layer is thin, the curing time will be short. When the amount of glue applied is large, the moisture content of the cured glue will be relatively insufficient, and the curing time will be longer, which will ultimately affect the bonding strength of the structural parts.

4. Dispensing opening time

The specific time for the PUR hot melt adhesive applied on the sample to be exposed to the air should be based on the parameters of the adhesive. Generally, within one minute or less, the composite bonding effect is optimal. Complete the bonding within the effective opening time to prevent the glue line from drying out due to too long opening time, resulting in poor wetting effect of the glue line and thus affecting the strength of the bond.

5. Pressing

The structural parts after assembly with PUR hot melt adhesive must be pressed together, the time should be no less than 15 seconds, and the pressure should be no less than 3 kg. The purpose is to make the glue form a good glue thickness and glue wetting effect between the two bonding surfaces.

6. Ambient temperature and humidity

PUR hot melt adhesive is cured by moisture in the air. If the ambient humidity is high, the curing time will be short. On the contrary, if the time is long and the ambient temperature is high, it is conducive to the participation of moisture in the reaction, and the curing time will be shortened accordingly.

7. Adhesive surface treatment

Removing oil, dust, paint, release agents, oxide layers and other substances that affect bonding on the surface of the bonded parts will help enhance the bonding effect of PUR hot melt adhesive.
