Transmission mechanism provided with wedge sliding block

Abstract

The invention discloses a wedge slider transmission mechanism, which comprises a drive block fixed on the bottom side of an upper template and a wedge slider slidably installed on the top side of a lower template. One side of the wedge slider is fixed with a side shaping knife block. From top to bottom, the driving block is a vertical fixed section and a driving section inclined opposite to the driving direction of the wedge slider; a guide groove is provided on the top of the wedge slider, and the guide groove is close to the side shaping knife block. The inclined surface on the side is the driving surface, and the inclined surface on the side of the guide groove away from the side shaping knife block is the returning surface; when driving, the driving block cooperates with the driving surface, and there is a gap between the returning surface and the driving block; when returning, the driving The block cooperates with the return surface, and there is a gap between the driving surface and the driving block. This scheme completes the left and right movement of the slider through the direct cooperation of the drive block installed on the upper template with the wedge slider, so as to complete the shaping and withdrawal of the plastic knife block. There is no need to add a separate elastic part to return the slider to complete the exit. Simplified structure, low manufacturing and maintenance costs.

Description

technical field [0001] The invention relates to the field of stamping devices, in particular to a wedge slider transmission mechanism. Background technique [0002] The part processing method perpendicular to the stamping direction is a common processing method in the part processing process. At present, the driving method of the horizontal forming knife block adopts the form of a lifting wedge, that is, the upper and lower dies are each equipped with an oblique block. The oblique block of the block cooperates, and the downward movement of the upper inclined block and the lower inclined block cooperate to drive the horizontal movement of the side shaping knife block during the downward movement of the upper mold. The return stroke needs to be equipped with a spring dedicated to the return stroke. [0003] Because the components of this traditional wedge drive mechanism are relatively complex, the movement coordination between the various parts is relatively laborious and tak...
