Production line performance characteristics:

This production line is a piece of special forming equipment for the production of shelf laminates. The strip coil to be processed is manually placed on the unloading rack, and then corrected and tensioned. After power leveling and hydraulic pre-punching, it is sent to the forming machine by the guide device to form the workpiece. Under the effect of frictional damping of the pressure roller, after entering the cutting part at a linear speed of 0-12m, the product is punched, cut and folded as required, and then manually packed away.

Equipment structure and system configuration:

Overview: This production line is mainly composed of uncoiler machine, leveling machine, hydraulic punching machine, cold roll forming machine, shut-off and hemming part, finished product unloading collection device, electrical control part and safety protection part.

1. Uncoiler machine:

It is used to deposit the unwinding material and provide the sheet to the forming part. The 3-ton electric unwinder is manually tensioned.

2. Cold-formed host:

The mainframe of this production line is welded by 100X100X4mm square tube, the side plate is 25mm steel plate, both sides are finely ground, the supporting parts are made of high-quality Taiwan bearings, the feeding is roller type, and the output is twisted up and down adjusted, the host has good rigidity and stable structure.

Rolling mold (rolling mill): 8 groups of rollers are formed, all adopt high-quality gGr15 bearing steel, HRC up to 62-64 are all processed by precision CNC machine tools, precision is 6-7, surface roughness is above 0.8, forming Precise dimensions, no scratches on the surface of the formed workpiece.

Transmission part: It is the conveying part of the forming power of the production line. The power is transmitted from the main motor to the reduction gearbox and then transmitted to the driving wheel by the gearbox through the gearbox.

3. Fixed-length cutting part: It consists of a fixed-length device and cutting mechanism. The fixed-length device is fixed by an encoder. When the formed sheet reaches a fixed length, it is controlled by a PLC to cut off the product.

4. Supporting rack: This device is located at the back of the forming machine and is reasonably arranged according to the length of the product.

5. Electric control system: The entire production line adopts centralized control, the components adopt imported and domestic top-quality products, or specified by customers, and the pneumatic components adopt the Taiwan brand. The installation of the equipment's electronic control components complies with national regulations, with clear line numbers, reasonable bureaus, clean control panels, and clear labels.

6. Security protection: The host is equipped with a protective net, and warning signs are set on the parts involving personal safety. The electrical appliance has reliable safety grounding, and the emergency stop button is also provided on the die end to protect personal safety to the greatest extent.
