Hole punching and flanging punching mold

Abstract

The invention provides a hole punching and flanging punching mold, which comprises an upper mold and a lower mold, wherein the upper mold is sequentially connected with an upper support plate, an upper pad block, an upper mold seat, an upper pad plate, an upper clamp plate and an upper stripping plate from top to bottom; the lower mold is sequentially connected with a lower support plate, a lower pad block, a lower mold seat, a lower pad plate and a lower template from bottom to top; a punching head is fixedly arranged on the upper clamp plate, and is connected with a spring a arranged on the upper stripping plate; the lower end of the spring a is connected with a material jacking pin; a special-shaped punching element is also arranged on the upper clamp plate; a nitrogen gas spring a is arranged on the lower mold seat, and is connected with a lower template entering plate a arranged on the lower template; a flanging punching element is arranged on the lower mold seat, and sequentially passes through the lower pad plate and the lower template; a spring b is also arranged on the lower mold seat; the spring b is connected with a lower template entering block b. The mold provided by the invention has the advantages that the structure is reasonable; the functions of hole punching, flanging and shaping are realized; meanwhile, the punching effect is good; the precision is high; the process requirements and the shaping effect of the workpiece are ensured; the defect rate is effectively reduced; the production efficiency is improved; the production cost is reduced.

Description

technical field [0001] The invention relates to a stamping die, in particular to a stamping die for punching and extracting teeth. Background technique [0002] With the continuous improvement of the quality of industrial products, the variety, small batch, complex and large-scale precision of mold products are rapidly updated. Mold design and technology Due to manual equipment, relying on manual experience and conventional machining, the technology has changed to computer-aided design, NC programming chip processing, and computer-aided design technology with the core of NC electric machining. The high precision, high complexity, high productivity, high consistency and consumption of mold production parts can not be fully displayed in other manufacturing and processing, so it has good economic benefits, so it is widely used in mass production , has a very important position in modern industrial production, and is an indispensable processing method in my country's national de...

Problems solved by technology

Because of the complexity of the workpiece, if the workpiece is operated in a single process, it will increase the difficulty of the next process. At the same time, the operation of this process will affect the accuracy of the previous process, which will seriously cause defects such as wrinkling and surface damage on the outer surface, and waste products. High efficiency, can not get a higher surface quality, but also increases the production cost, reduces the production efficiency, cannot guarantee the high precision of the workpiece
