Folding Machine：
The folding machine mechanism is a simple bending machine, either manual or motorized. The simple method is to firmly secure the steel plate to the machine table using a model with a curved radius.
The extended portion of the material is placed on another table that can rotate along the center of the bend radius. When the movable table rises, it bends the stainless steel to the desired angle. It is obvious that the stainless steel slides on the table when bending. Therefore, in order to prevent scratching of stainless steel, the surface of the table must be smooth. In the actual processing, the stainless steel surface is usually protected with a plastic film.
The upper beam is typically wedge-shaped to form a gap so that a suitably shaped blank can be folded into a quadrilateral box or slot. Folding machines have been used to produce a wide range of simple stainless steel sheet products, but these products are currently produced more often with cold bend presses.
The difference between the folding and bending principles:
The bending machine controls the bending angle of the upper knife to control the bending angle. At the same time, when bending, the short side, the operator needs to hold most of the material outside. When the large workpiece is bent, two or More employee assistance.
The working principle of the folding machine is that after the plate is placed on the workbench, the side beam is pressed down to fix the plate, and the folding side beam is turned up and down to realize the folding. In all the folding processes of one side, no manual is needed. Participate in positioning and assisting in turning and positioning work.
The difference in bending accuracy:
1.The dimensional accuracy of the bending machine control is the short-edge dimensional accuracy of the back gauge positioning. After the bending is completed, the error accumulates to the inner space size. At the same time, the bending angle is controlled by controlling the upper die pressing amount. Relevant to the thickness of the material.
2.The dimensional accuracy of the folding machine control is to complete the folding edge, and the edge is used as the positioning reference. The size of the control is the inner space size required by the customer, and the bending angle is the direct control of the flange angle. It doesn’t matter.
3.Problems with scratches on the surface of the material:
When the bending machine is working, the material will move relative to each other in the lower die, and at the same time, it will leave an indentation without surface protection. At the same time, when bending a large workpiece, it is necessary to turn over and move many times, and it is inevitable that scratches will occur during the process.
When the hemming machine is working, no relative movement of the edge beam cutter and the hemming beam cutter and the material can completely avoid surface damage. When the large workpiece is bent because the sheet is flat and processed at the same time, all the processing of one side of the workpiece can be completed, and the surface damage is completely avoided.
4.The technical requirements of workers are different:
The bending machine has a relatively higher technical requirement for the bending workers.
The programming of the folding machine can be intuitively programmed by means of finger painting or offline programming by the engineer using software and imported into the processing program by USB or network connection. After the programming is completed, the main work of the worker becomes a simple loading and unloading work. No need to skillfully bend workers.
5.Tool configuration:
When the bending machine needs to implement certain special bending (such as arc), it needs to change the tool or transfer it to another machine to increase the transfer and temporary storage of the semi-finished product.
The folding machine can be configured by rotating the blanking beam design, and installing two sets of blanking beam tools at the same time so that all the bending operations can be completed in a single station. For arc bending or other special bending requirements, there is basically no need to change the tool. It can be fully implemented simply by making changes in the program.
6.Tool life:
Due to the relative movement of the workpiece in the die, the tool will wear and be repaired or replaced.
The folding machine basically avoids the relative movement between the material and the tool, and the tool has almost no wear for a long time, which greatly extends the tool life.
7.Operating position:
A. The press brake can only be operated from the front.
B. The folding machine can be operated both front and rear according to the size of the workpiece, which is convenient for observation and use.
8.Drive system:
A. The bending machine is hydraulically driven, which brings more maintenance work and is susceptible to environmental factors.
B. The folding machine adopts an all-electric drive design, which reduces the maintenance workload and has nothing to do with the use environment. Thereby achieving higher bending accuracy.
