Problems solved by technology

[0004] The existing punching machine has the following disadvantages: after the space at the bottom of the pressing core of the frame structure is increased, the overall size of the pressing core is increased, and the overall size of the mold is also increased accordingly, which increases the cost of mold development; furthermore, due to the The increased size requires a larger working surface of the stamping machine tool, which also increases the cost of stamping production to a certain extent

Abstract

The invention provides a two-stage transmission pressing structure, the cutting tool of the punching machine is installed on the upper mold horizontal plate of the upper die base, the two-stage transmission pressing material structure includes an elastic element fixed with the upper die base, and the The secondary transmission backing plate connected to the elastic element, the binder core body fixedly connected with the secondary transmission backing plate, the secondary transmission backing plate and the binder core body are respectively located on the two sides of the upper mold horizontal plate On the side, the binder core body has a through hole for the tool to pass through. The two-stage transmission pressing structure has a compact structure and a reasonable longitudinal layered arrangement.

Description

technical field [0001] The invention relates to the field of forging machinery, in particular to a secondary transmission pressing structure. Background technique [0002] Die processing usually uses a pressing structure. Before the stamping is processed by the mold, the pressing structure first presses the stamping, so that the processing process and quality are well controlled. The binder structure is usually composed of a binder core and related accessories. Such as figure 1 As shown, the mold used for processing slender stamping parts has a relatively small space at the bottom of the corresponding pressing core body 23'. When designing the pressing core, the necessary working parts (elastic element 21', side pin 6', guide Sliding plate 5', etc.) does not have sufficient space arrangement, and when the upper mold base 1' moves close to the lower mold base 4', the function of the binder core body 23' cannot be fully guaranteed. [0003] In order to solve the above-menti...
