Description

Technical Field

[0001] The invention belongs to the technical field of bending machines, in particular to a stainless steel plate bending machine. Background Art

[0002] Stainless steel plate bending machine is a mechanical equipment specially used for bending stainless steel plates. A bending machine is a mechanical equipment used to bend metal plates or other plastic materials into the desired shape by applying force. This equipment is widely used in the metal processing industry, such as manufacturing metal furniture, automotive parts, building structures, electrical equipment, etc. The main function of the bending machine is to bend metal plates into specific angles or shapes.

[0003] The staff places the stainless steel plate on the processing table of the bending machine, and pushes the bending die downward to squeeze the stainless steel plate through the oil cylinder to achieve the required bending shape. However, the existing bending machine does not have a device for clamping and fixing the stainless steel plate. When the stainless steel plate is squeezed, both ends of the stainless steel plate will be warped, thereby affecting the subsequent production process and bending efficiency of the stainless steel plate. At the same time, when the stainless steel plate is warped during the extrusion process, it will pose a great threat to the staff's own safety. When the stainless steel plate is warped, the staff may be accidentally injured, which increases the staff's own danger in the process, reduces the bending speed of the stainless steel plate, and reduces the quality of the stainless steel plate after bending. Most of the punching heads on the existing bending machines are fixed by the cooperation of nuts and bolts. After the punching head is used for a long time, it may be worn. The staff needs to manually unscrew multiple sets of nuts and bolts to remove it, which invisibly increases the staff's labor force and has low disassembly efficiency. Therefore, a stainless steel plate bending machine is proposed. Summary of the invention

In addition, most of the punching heads on the existing bending machines are fixed by the cooperation of nuts and bolts. After the punching heads are used for a long time, they may be worn out, and the workers need to manually unscrew multiple sets of nuts and bolts to disassemble them, which invisibly increases the labor of the workers and has the problem of low disassembly efficiency.
