Abstract

The invention discloses a rotational inclined wedge mechanism. A base is fixedly arranged inside a lower die holder of the rotational inclined wedge mechanism and is provided with a pair of connecting lugs arranged oppositely in the longitudinal direction and a base plate connected between the connecting lugs, and rotating shafts with axes coincide in the longitudinal direction are fixedly arranged on the connecting lugs; a rotating portion and the rotating shaft are arranged in a matched mode through a shaft sleeve, the rotating portion can rotate relative to the rotating shafts, and the rotating portion rotates to a working position under the pushing function during the movement of an inclined wedge sliding block and rotates to a workpiece picking position under the reset function of a driving elastic piece; the inner surface of the base plate is provided with two planes which are connected at an angle, and the two planes are respectively a first limit plane and a second limit plane against which the bottom plane of the rotating portion abuts at the working position and the workpiece picking position; a positioning block is arranged on a return stroke cylinder in the lower die holder and is clamped between the lower die holder and the rotating portion when the return stroke cylinder is in a state corresponding to the working position to limit the rotating portion to rotate relative to a lower die. According to the rotational inclined wedge mechanism, through the improvement on rotating and positioning structures, the manufacturing costs and the overall size of the rotational inclined wedge mechanism are optimized.

Description

technical field [0001] The invention relates to a rotary wedge mechanism for turning sideways of a stamping part in an automobile stamping die, in particular to an improved design of the rotation and positioning structure of the rotary wedge mechanism. Background technique [0002] With the continuous development of the car industry, the flanging angles of body parts such as side panels, fenders, bonnet outer panels, trunk lid outer panels, and roof covers of many models are mostly designed as negative angles to achieve The purpose of increasing the bite force of stamping parts and improving the strength and appearance quality of the body. The flanging of body parts is at a negative angle. If an ordinary slider-type wedge mechanism is used, the mold structure will be very complicated, and the cost of processing and maintenance will increase. become a trend. [0003] The patent document with the application publication number CN102836924A discloses a rotary cam mechanism, t...
