Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a bending machine for the steel structure of civil air defense doors. Background Technique

[0002] When manufacturing civil air defense doors in civil air defense projects, the main materials required include: carbon steel plates, stainless steel plates, rubber sealing strips, hardware fittings, etc. The processing of steel plates is the first process in the production of civil air defense doors, including shearing, stamping, cutting, bending, etc. The ends of the steel plates usually undergo bending operations to facilitate subsequent assembly.

[0003] In a bending machine for processing civil air defense doors disclosed in the existing patent publication number CN211489139U, it includes a machine body. On one side of the machine body, there is a support seat. One side of the top of the support seat close to the machine body is fixedly provided with a first support plate, and the other side of the top of the support seat away from the machine body is slidably connected with a second support plate. One end of the first support plate close to the second support plate is rotatably connected with a horizontal lead screw, and the end of the lead screw away from the first support plate is threadedly connected with the second support plate. By adopting the above technical solution, when an operator places the sheet material of the civil air defense door at the bending assembly for bending processing, the end of the sheet material away from the bending assembly is placed on the first support plate and the second support plate, and the first support plate and the second support plate play a role in supporting the sheet material. The operator rotates the lead screw according to the width of the sheet material to adjust the position of the second support plate on the support seat, further increasing the range of the width of the sheet material supported by the second support plate.

[0004] The above bending machine can perform bending of sheet materials. However, during bending, the first support plate and the second support plate can support the sheet material, but the placement stability of the sheet material and the feeding stability after bending still need to be improved. In view of the above problems, a bending machine for the steel structure of civil air defense doors is proposed. Content of the Utility Model
