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 secondary transmission pressing structure. A cutter of a punch is installed on an upper die transverse plate of an upper die base. The secondary transmission pressing structure comprises an elastic element, a secondary transmission base plate and a pressing core body, wherein the elastic element is fixedly connected with the upper die base, the secondary transmission base plate is connected with the elastic element, the pressing core body is fixedly connected with the secondary transmission base plate, the secondary transmission base plate and the pressing core body are located on the two sides of the upper die transverse plate respectively, and a through hole allowing the cutter to penetrate is formed in the pressing core body. The secondary transmission pressing structure is compact in structure and reasonable in longitudinal layering 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...
