Clamp elliptical washer cutting die

Abstract

The invention relates to a clamp elliptical washer cutting die. The clamp elliptical washer cutting die comprises an upper die and a lower die. The upper die comprises an upper die punch pin box and astripping plate. The upper die punch pin box comprises an upper male plate and an upper male die. The top of the upper male die is vertically arranged at the bottom center of the upper male plate. The center of the bottom of the upper male die is provided with an ejector pin groove. The outer wall of the upper male die is sleeved with the stripping plate. The stripping plate can slide up and downalong the outer wall of the upper male die. A first elastic part is arranged between the stripping plate and the upper male plate and used for pushing the stripping plate downwards to enable the bottom of the stripping plate to be flush with the bottom of the upper male die. The lower die comprises a bottom plate and a lower tool edge. The lower tool edge is fixedly arranged at the top center ofthe bottom plate. The middle portion of the lower tool edge is provided with a male groove matched with the upper male die and penetrating through the lower tool edge vertically. An ejector pin is vertically arranged at the center of the bottom plate, located in the male groove and matched with the ejector pin groove. The central axis of the upper male die, the central axis of the male groove, thecentral axis of the ejector pin and the central axis of the ejector pin groove are located on the same straight line. The qualified rate of products is greatly increased. The production efficiency isimproved. Time, labor and devices are saved. The clamp elliptical washer cutting die is safer in operation.

Description

technical field [0001] The invention relates to a mold, in particular to a cutting mold for clip oval gaskets. Background technique [0002] Molds are molds and tools used in industrial production to obtain the required products by forging, smelting, stamping and stretching. Requirements; Clip elliptical gaskets are used as connection and fastening accessories, mainly used for the connection and fastening of tray plates, tray plates and support parts in the internal parts of chemical plant tower equipment, which require high processing accuracy. Traditional processing methods Divided into two processes, the operation is unsafe, and there may be inaccurate positioning in the processing gap between the two processes, which takes a long time and the operation efficiency is low. Contents of the invention [0003] In view of this, the present invention discloses a cutting die for clip elliptical gaskets, which not only has precise positioning, but also completes two processes ...
