Anti-deformation pipe punching stamping die

Abstract

The invention provides an anti-deformation tubular product punching and stamping mold which comprises a positioning and adjusting module and a punching module, wherein the positioning and adjusting module comprises a base, a positioning base is arranged at the upper end of the base, and a fixed slot is formed in the positioning plate; a through hole is formed in the center of circle of the fixed slot, and a threaded rod is assembled in the through hole; positioning holes are formed in two sides of the through hole, and positioning bars are slidably assembled in the positioning holes; the positioning and adjusting module comprises a round supporting plate, a threaded hole is formed in the center of the supporting plate, and positioning hobbles are formed in two sides of the threaded hole. The anti-deformation tubular product punching and stamping mold is structured such that a tubular product in punching process has an enough supporting force to prevent deformation by mounting a supporting structure in the tubular product; in addition, the position of the supporting structure can be adjusted corresponding to the punching position through a threaded transmission structure inside, sothat a supporting effect during porous processing is achieved.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a punching stamping die. Background technique [0002] Punching is the operation of punching out holes for pipes, plates, etc. Usually, punching is performed through a stamping die. In the punching operation of the pipe, the pipe is generally fixed on the stamping die by a fixing fixture, and then the punching operation is performed manually or automatically; since there are many types of materials used in the pipe, the hardness of the material is relatively high. Small pipes will be deformed when they are punched again, but there is no equipment that can solve this problem in the existing pipe punching structure, so there will be a large number of scrapped parts during the punching operation, which is not conducive to saving The cost of pipe punching. In addition, in the existing pipe punching process, usually only one hole can be processed in one punching operation, which can gre...

Problems solved by technology

In the punching operation of the pipe, the pipe is generally fixed on the stamping die by a fixing fixture, and then the punching operation is performed manually or automatically; since there are many types of materials used in the pipe, the hardness of the material is relatively high. Small pipes will be deformed when they are punched again, but there is no equipment that can solve this problem in the existing pipe punching structure, so there will be a large number of scrapped parts during the punching operation, which is not conducive to saving The cost of pipe punching

In addition, in the existing pipe punching process, usually only one hole can be processed in one punching operation, which can greatly avoid the deformation of the pipe due to the overall excessive force during punching, but such processing efficiency Low, not conducive to saving punching processing time

In addition, in the pipe punching process, for the punching process with a small hole spacing, since the distance between the holes is small, in the punching process, the supporting force of the pipe material for the punching process position will also increase accordingly. becomes smaller, so it is more prone to deformation and bending during processing, which affects the processing quality

In the punching process, the punching operation method is usually from the outside to the inside, so after punching, there will be burrs inside the pipe, which is difficult to clean and process, so it will also affect the quality of the pipe processing
