Intra-mold tapping machine for punch

Abstract

The invention discloses an intra-mold tapping machine for a punch. The intra-mold tapping machine comprises an upper mold and a lower mold. The upper mold is located above the lower mold. First support pillars are fixedly mounted at the two sides of the outer surface of the lower end of the upper mold. A connecting pillar is fixedly mounted on the outer surface of the lower end of each first support pillar. A movable groove is formed inside the upper mold. A fixing block is fixedly mounted inside the movable groove. A first movable pillar and a second movable pillar are movably mounted at thetwo sides of the outer surface of the front end of the fixing block correspondingly. A movable seat is movably mounted on the outer surface of the lower end of the first movable pillar. A screw tap isarranged inside the movable seat in a penetrating manner. The outer surface of the screw tap is wrapped by a rotating shaft. According to the intra-mold tapping machine, by means of a series of structures, when the intra-mold tapping machine is used, tapping can be conducted on an oblique face of a punched sheet metal part at any angle; the sheet metal part of any specification can be punched; the application scope of the machine is widened; and the using process is optimized.

Description

technical field [0001] The invention relates to the technical field of an in-mold tapping machine, in particular to an in-mold tapping machine for a punch press. Background technique [0002] In-mold tapping machine, also known as in-mold tapping machine, is a device that cooperates with continuous metal molds to quickly process screw holes while stamping hardware parts. It is the most advanced screw hole forming process for hardware parts at present, breaking the traditional processing method. , its core is to integrate the traditional stamping and tapping technology together and form it directly in the mold. Its main working principle is that when the punch slider goes down, the screw pushes down the nut in the gearbox to rotate, thereby driving the tap to tap on the product. When the slider of the punch press goes up, the screw pulls up the nut in the gearbox to reverse, and finally drives the tap to exit the product. [0003] However, the existing in-mold tapping machin...

Problems solved by technology

[0003] However, the existing in-mold tapping machines for punching machines have a simple structure and are not good enough to use. They cannot tap the stamped sheet metal parts on an inclined plane at any angle, and the height of the tap is unique and cannot be changed. It can only punch specific specifications. Sheet metal parts limit the scope of use of the machine and greatly reduce the efficiency of the machine
