Die and covered edge press fit mechanism thereof

Abstract

The invention discloses a die and a covered edge press fit mechanism thereof. The covered edge press fit mechanism comprises a covered edge driving cylinder installed on a fixed plate through a cylinder barrel of the covered edge driving cylinder, a telescopic rod of the covered edge driving cylinder penetrates a cylinder rod through hole in the fixed plate, the tail end of the telescopic rod is fixedly connected to an installing plate, and the installing plate is fixedly connected to a covered edge knife block. The fixed plate is installed on an installing base, and the lateral end face of the installing base is rotatably connected with a telescopic rod of a switchover cylinder through a driving shaft. The bottom end face of the installing base is rotatably connected with an installing support through a rotating shaft, the installing support is fixedly connected to a die body, and the rotating shaft is parallel to the driving shaft. A first control valve for controlling the covered edge driving cylinder to extend and a second control valve for controlling the switchover cylinder to extend are installed on the die body. The covered edge press fit mechanism is simple in structure and high in stability.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an edge wrapping and pressing mechanism for moulds. The present invention also relates to a mold comprising the above-mentioned hemming pressing mechanism. Background technique [0002] With the vigorous development of automobile technology, the change of models is accelerating, and the shape of automobiles is becoming more and more novel. The dividing line of the outer cover of the automobile is different from the conventional one, resulting in a small pressing angle of some assembly parts. The conventional vertical pressing mechanism is adopted. , it is easy to cause deformation of the outer plate, resulting in defects such as double ridges at the edge of the R corner of the outer plate and unreal pressing of the inner and outer plates, so that the assembly cannot meet the requirements of the relevant surface products, which requires setting in the mold Hemming and pressing mec...

AI Technical Summary

Problems solved by technology

[0005] However, the structure of the existing hemming pressing mechanism is relatively complicated, the stability is poor, and the cost is high; and the driving block moves downward to contact with the driving plate of the driving mechanism on the lower die, and the driving process is sliding Friction, high friction, high noise, shorten the service life of the mechanism, and increase maintenance costs; in addition, the return stroke of the hemming pressing mechanism is unstable, the mechanism occupies a large space, wastes mold space, and increases tooling development costs
