Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of forming equipment production technology, especially a kind of male die ejection mechanism of forming machine upsetting. BACKGROUND

[0002] In prior art, the male die ejection of forming machine is mostly driven by cam block in relative motion on slide or connecting rod to realize. But generally, when the design requirement male die ejection stroke changes, new cam block is often replaced to match stroke change. This way can change ejection stroke, but it is time-consuming and laborious, and when the design requirement stroke changes little, only fine-tuning is needed, this problem is particularly prominent. Under this background, it is particularly necessary to design a new type of male die ejection mechanism to match fine-tuning stroke requirement working condition application. SUMMARY

[0003] The utility model discloses a kind of male die ejection mechanism of forming machine upsetting, which can change ejection stroke conveniently without replacing new cam block.

[0004] To achieve the above object, the utility model discloses a kind of male die ejection mechanism of forming machine upsetting, including male die ejection cam block, swing fork and roller on swing fork, characterized in that male die ejection cam block is equipped with the travel curve that roller on swing fork rolls and walks, top cam block adjusting support for adjusting the travel position of roller on travel curve is further equipped on male die ejection cam block, and top cam block adjusting screw is equipped on top cam block adjusting support;Male die ejection cam block is relatively fixed on top cam block base by top cam block adjusting support, top cam block base is fixed on top cam block base support frame, and the relative position of male die ejection cam block and top cam block base is adjusted by top cam block adjusting screw of top cam block adjusting support.

[0005] To ensure that top pressure roller safely walks on the travel curve of male die ejection cam block, spring for top pressure roller on travel curve is equipped between swing fork and slide.

[0006] To make spring have good positioning, spring is positioned and fixed between swing fork and slide by spring seat.

[0007] When in use, the punch top ejection mechanism of the forming machine is placed above the slide table, and is fixed on the bed through the top ejection cam block base support and the top ejection cam block base. The punch top ejection cam block is fixed on the top ejection cam block base. When the slide table retreats, the roller installed on the swing fork is on the stroke curve on the punch top ejection cam block, the swing fork is pressed down, the boss is ejected forward, and the punch top ejection action is completed. When the slide table slides forward to the dead point, the roller on the swing fork is always close to the punch top ejection cam block due to the restoring force of the spring, and the swing fork is slowly returned to the initial position again through the stroke curve. Such a reciprocating is a punch top ejection action.

[0008] The punch top ejection mechanism of the forming machine has the following advantages: 1) the punch top ejection stroke of each station is independently adjustable; 2) the punch top ejection stroke can be finely adjusted without replacing the punch top ejection cam block, thereby saving time and cost; 3) the structure is simple, and the number of parts is less than that of a conventional structure; and 4) the slide table retreat and the punch top ejection can be synchronized, and the stability of the workpiece in the mold cavity is ensured.
