Feeding mechanism for bushing forming tools for punching machines

Abstract

The invention provides a feeding mechanism of a bearing bush molding tool used for punches. The feeding mechanism is arranged at the right side of a circular bending die of the bearing bush molding tool and comprises a slide way adjoining the circular bending die, a sheet stock bin and a push unit, wherein the slide way is formed by oppositely arranging two base plates with L-shaped sections at intervals; the push unit comprises a cylinder, an upper push plate and a lower push plate; the cylinder is arranged at the right side of the sheet stock bin; the lower push plate is used for pushing out molded bearing bushes in the circular bending die; an upper surface of the upper push plate is a cambered surface gradually descending from left to right; a left top of the upper push plate is arranged above upper surfaces of transverse edges of the base plates, and a right top of the upper push plate is arranged below the upper surfaces of the transverse edges of the base plates; and the lower push plate is arranged below an upper surface of the circular bending die. The feeding mechanism achieves mechanically automatic feeding, and not only can achieve the effect of improving the work efficiency but also avoids potential safety hazards of manual operation.

Description

【Technical field】 [0001] The invention relates to an auxiliary mechanism for machining equipment, in particular to a feeding mechanism for a bearing pad forming tool of a punching machine. 【Background technique】 [0002] The bearing pad is one of the important components of the bearing. It is the contact part of the sliding bearing and the shaft. It is generally made of wear-resistant materials such as bronze and anti-friction alloy. Its shape is a half-cylindrical surface in the shape of a pad. The forming tool punches the sheet into a tile-shaped semi-cylindrical surface, that is, the bearing bush. [0003] Existing commonly used bearing pad forming tools such as figure 1 As shown, the bearing bush forming tool 100' includes a machine base 101', a stamping die 102', a pressing rod 103' and a circular pressing die 104' installed on the machine base 101', and the upper end surface of the circular pressing die 104' is provided with Two fixed platens 1041', the two fixed pla...

AI Technical Summary

Problems solved by technology

[0004] It can be seen from the above that the existing bearing pad forming tools manually send the sheet material to the circular die for stamping into the bearing pad, and the manual feeding not only leads to low work efficiency, but also has hidden dangers in operation safety
