Bending And Folding

Bending And Folding In recent years, 30% of the sheet metal factories in Europe and the United States and other developed countries have begun to use the folding machine to replace the traditional bending machine for part of the sheet metal bending. Compared with the bending machine, the folding machine is a bending equipment with many advantages, which is more convenient to operate. In this paper, making a simple introduction bending machine and folding machine, the figure below is the difference between the working principle of bending machine and folding machine.

Bending machine is divided into hydraulic bending machine and CNC bending machine, according to the mode of motion can be divided into up and down. According to the synchronous mode, hydraulic bending machine can be divided into torsion shaft synchronous and electric hydraulic synchronous. Bending And Folding

Numerical control bending machine realizes the bending function by controlling the slider stroke and back stop of the bending machine. When using CNC bending machine, as long as the part drawing of the work piece and the bending angle of each step are input, the bending machine will be realized one by one according to the input steps. The advanced CNC bending machine mainly adopts electric hydraulic servo system and grating ruler to form full closed-loop control, with high synchronous control precision, bending precision and repositioning precision.

In use, the CNC bending machine can be operated flexibly, which can realize the super long plate processing by double machine linkage, and can process parts by single machine operation. This not only improves the use efficiency of the bending machine, but also reduces the energy consumption. The bending machine comprises a bracket, a worktable and a clamping plate. The worktable is composed of a base and a pressing plate and is arranged on the bracket; The base is composed of a base shell, a coil and a cover plate, which is connected with the clamping plate through a hinge.

The coil is placed in the depression of the base shell, and the top of the depression is covered with a cover plate. When in use, the coil is electrified by the wire, and after being electrified, the pressing plate is attracted, so as to realize the clamping of the thin plate between the pressing plate and the base. The bending machine can meet the needs of various work pieces by replacing the bending machine mold. Bending And Folding

Folding machine is a simple bending machine, divided into manual folding machine and pneumatic folding machine. Bending And Folding

Folding machine is a kind of machine to process the edge of products. It is used to produce stainless steel sheet products with simple shape in a large scale. However, with the continuous updating and maturity of technology, these products are produced by cold bending punch. The folding machine uses the model with bending radius to fix the steel plate on the worktable of the machine tool, and the protruding part of the material is placed on the movable worktable, which can rotate along the center of the bending radius. Bending And Folding

When the movable table rises, the stainless steel can be bent to the required angle. When bending, because the stainless steel will slide on the worktable, in order to prevent material scratch, on the one hand, the worktable surface should be smooth, on the other hand, a layer of plastic film should be pasted on the stainless steel surface to prevent work piece scratch. The upper beam of the folding machine is usually made into a wedge to form a gap, so that the blank with proper shape can be folded into a quadrilateral box or groove. Typical legend of folding machine is shown in the figure below. Bending And Folding

1. Before operation, wear tight protective clothing, fasten the cuffs, keep the lower hem of the jacket open, and do not wear, take off or change clothes beside the machine tool, or put cloth around the body, so as to prevent the machine from wringing. Must wear a helmet, braids should be put into the hat, not to wear skirts, slippers. Bending And Folding
2. 접는 작업자는 특정 전문 연구를 수행하고 작업하는 공작 기계의 구조와 성능을 이해하고 금형을 올바르게 설치하여 독립적으로 작동 할 수 있어야합니다.

상단 빔 조각은 일반적으로 쐐기 모양으로 틈을 형성하므로 적절한 모양의 블랭크가 있는 사각형 상자 또는 홈으로 접힐 수 있습니다.

접는 기계는 다양한 단순 형상의 스테인리스 스틸 또는 아연 도금 시트 제품을 생산하는 데 자주 사용되지만 이러한 제품은 대부분 냉간 벤딩 펀치로 생산됩니다.
