Punching head structure

Abstract

A punching head structure comprises a fixed plate, two clamping structures, an ejection structure, a punching structure and a control unit, wherein a through hole is formed in the middle of the fixedplate, and a first supporting piece and two second supporting pieces are arranged on the two sides of the through hole respectively; each clamping structure comprises an inner support block, a plurality of sliding rods, a first elastic element and a clamping block; the ejection structure comprises an ejection block, an ejection rod and a first pushing mechanism; the punching structure comprises asecond pushing structure, a guide sliding plate, two guide sliding shafts, a pushing plate, a plurality of second elastic elements, a pressing plate and a plurality of punching blades; and the controlunit is connected with the first pushing mechanism and the second pushing structure and controls the opening and closing of the first pushing mechanism and the second pushing structure. By utilizingthe punching head structure, the problem that at the present stage, a metal part is extremely prone to deformation due to clamping by a chuck of a lathe, and consequently the size precision, shape precision and position precision of a workpiece are affected is solved.

Description

【Technical field】 [0001] The invention relates to a punching head structure, in particular to a punching head structure for metal parts. 【Background technique】 [0002] At present, metal parts need to be clamped by the chuck of the lathe when processing the punching head, but when the wall thickness of the metal part is thin, the rigidity and the processing technology are poor, it is easy to be clamped under the clamping force of the chuck. Deformation occurs, thereby affecting the dimensional accuracy, shape and position accuracy of the workpiece. At the same time, due to the thinner wall thickness of the metal parts, the punching heat generated during the punching head processing operation will cause thermal deformation of the thin-walled metal parts, making it more difficult to guarantee and control the size of the metal parts. [0003] In view of this, it is necessary to develop a punching head structure to solve the problem that metal parts are easily deformed by the c...
