Pyramid 3 roll plate rolling machine with end pre-bending function

In China, for a long time, pyramid-type three-roll plate rolling machines were often used in the pre-bending of copper plate ends for production. The internal structure of the pyramid three-roll plate bending machine is relatively simple, and the end of the workpiece after the bending process has a certain length of straight edge, which results in very low production efficiency.

Fully automatic 4 roll plate rolling machine

In view of various problems in the end pre-bending of copper sheets and carbon steel sheets, some companies in the market have introduced fully automatic four-roller plate rolling machines. The fully automatic four-roll plate rolling machine can detect the curvature of the pre-bent end of the copper plate in real-time, and correct the processing parameters in real-time, which can well solve the problems existing in the plate rolling process.

This paper discusses the structure of the fully automatic four-roll plate rolling machine, and analyzes the principle of applying the fully automatic four-roll plate rolling machine in the pre-bending of the copper plate end.

Copper sheet roll bending process and the plate rolling machine

A fully automatic CNC four-roll plate roller is an advanced profile bending equipment, which can bend metal plates (such as carbon steel and copper plates) into circular and conical shapes, and can also pre-bend the ends of metal plates. The pre-bent arc is very accurate.

The application of a CNC automatic four-roller plate roll machine in the metal bending workshop has changed the simple structure of the original pyramid-type three-roller plate bending machine, and the operation process is simple and clear. The use of a CNC automatic four-roller plate rolling machine not only improves the production efficiency of the entire copper plate enterprise but also improves the accuracy of the pre-bending of the entire copper plate end, which is conducive to future development.

Pre-bending and bending process of four-roll plate rolling machine

During the working process of the four-roller plate rolling machine, the metal plate is firstly centered, then the metal plate is pre-bent, then rolled, and finally rounded.

Alignment of the sheet metal: When aligning materials, it is necessary to find the correct position, that is, in the middle of the upper and lower roller shafts in front of the sheet. When one side roller rises, the other side roller must be in time with the sheet. Bottom alignment.

Pre-bending: Then press the plate on the lower roll, and immediately raise the upper roll to bend the end of the plate. When pre-bending the end of the copper plate, the copper plate material does not need to be taken out of the equipment, and the copper plate can be directly moved to the other end, and the same method is used to pre-bend the copper plate.

Force analysis of the end of the copper plate: when the fully automatic four-roller plate bending machine pre-bends the end of the copper plate, the bearing force on the section should be along the height direction of the copper plate.

CNC four-roll plate rolling machine in the pre-bending of copper plate ends

Usually, the copper plate end pre-bending equipment uses a fully automatic CNC four-roller coiling production line with touch screen mode. There are two main ways to control the fully automatic CNC four-roll coil production line in touch screen mode, one is automatic mode and the other is manual control mode.

CNC automatic bending process

By starting the computer program and ordering the pre-determined program, the fully automatic CNC four-roll coil production line can be controlled and operated by itself.

The pre-bending of the copper plate end uses a fully automatic CNC four-roller coiling production line to make the operation process simple and clear, and it is easier for the operator to operate.

The application of the fully automatic CNC four-roll coil production line in the pre-bending of copper plate ends can be reflected in the operation of two circulation systems. One is the workpiece (plate) preparation loading circulation system, and the other is the workpiece loading circulation system.

The workpiece (plate) pre-loading cycle system is checked by the corresponding workpiece (plate) loading platform to see if there is a copper plate, and then the copper plate is pulled into the pre-loading sequence, and the automatic loading device confirms whether the copper plate is loaded, and then the plate is carried out Displacement, and finally, copper sheet rolling.

The workpiece loading cycle system is loaded by the feeding cylinder, and the loading device is pressed under the roller. At this time, the loading device starts to rotate and feed the plate and performs the work of rolling. When the rolling is completed, the loading device is moved from the roller The bottom rises up to the top of the cylinder, and finally the preparatory loading process is performed on the cylinder.

Remark

The pre-bending of the copper plate end requires the high cooperation of the fully automatic four-roll plate rolling machine to complete. There are 15 vacuum suction cups in the workpiece loading device. When the vacuum setter has an angle, the feeding platform starts to tilt. When the tilt reaches a certain angle, the copper plate on the feeding platform starts to correct its position. After the correction of the position is completed, the sheet is pushed between the upper and lower rollers to realize the feeding work.

Epilogue

The fully automatic four-roll plate rolling machine production line has played a great role in the pre-bending of copper plate ends.
The fully automatic four-roll plate rolling machine production line has low noise, very stable operation, and very high production efficiency. , It also improves the overall economic benefits of copper plate enterprises.
