Feeding mechanism with holes punched on surface

Abstract

The invention relates to a feeding mechanism with holes punched on the surface; connecting rods (a, b, c, d) are hinged at corresponding parts by pins according to the correct requirement; simultaneously, a unified whole formed by an electromagnetic sucker, a reducing gear and a stepper motor through pins is hinged on one ends of the connecting rods (a, b); the other ends of the connecting rods (c, d) are hinged on a fixed bench; the parts form a parallelogrammic amplitude variable mechanism; simultaneously, the flexible rotation of all hinged joints is ensured; and finally, a piston cylinder of a cylinder is hinged with one hinge in the middle part of the parallelogrammic amplitude variable mechanism which is formed by the parts and is hinged with the fixed bench, an upper die, a lower die and a lower die body in an overall way so as to punch holes on the surface with different specifications.

Description

technical field

[0001] The invention relates to a punching and feeding mechanism, in particular to a surface punching and feeding mechanism. It belongs to the field of stamping technology. Background technique

[0002] In stamping production, parts that need to be punched on the surface of the cone are often encountered, such as the hubs of automobiles and other motor vehicles, and other similar parts, which often need to be punched on the surface of the cone. It is currently known that: Punching on the surface of the cone is realized by designing the corresponding mechanical positioning device in the mold. This kind of design of the corresponding mechanical positioning device mechanism in the mold not only has complex structure, low precision and high cost, but also is easy to be damaged due to the complex structure. , especially, this kind of mechanism is poor in versatility, and the corresponding mold and corresponding device must be replaced when the part is replaced or...
