Adjustable positioning device for open punching of press

Abstract

The invention relates to auxiliary positioning equipment used for machining forged pieces like a bearing ring through a press open process, in particular to an adjustable positioning device for open punching of a press. The adjustable positioning device for open punching of the press is characterized by comprising a pressing cover (2), wherein a through hole is formed in the middle of the pressing cover (2), at least three installation holes (6) are distributed in the outer wall of the pressing cover (2) in the peripheral direction, a telescopic positioning rod is installed in each installation hole (6), and the two ends of each telescopic positioning rod extend into and out of the outer wall of the pressing cover (2) respectively, so that a forged piece to be machined is clamped in the middle. The adjustable positioning device for open punching of the press has the advantages of solving the problems and overcoming the quality defects of an original open punching process, improving and guaranteeing the quality of products, largely reducing the investment and adjustment frequency of moulds, enabling production and machining to be more convenient, largely improving the production efficiency, and being applicable to products of various specifications through the telescopic adjustment of a spring and a spare cap.

Description

technical field [0001] The invention relates to an auxiliary positioning device for processing forgings such as bearing rings by adopting a press open process, in particular to an adjustable positioning device for press open punching. Background technique [0002] At present, in the bearing industry, in the press process for processing ferrule forgings, the ferrule blank is generally forged by a press, and then rolled and formed on a reaming machine to form an assembly line. When the press forges the ferrule blank, it generally adopts the layout of three stations: upsetting, punching, and bottom cutting, and the punching station is generally divided into reverse extrusion punching and open punching ( Also known as free punching), these two punching methods have their own advantages and disadvantages in terms of process characteristics. The advantage of reverse extrusion punching is that due to the role of the mold, the blank is punched correctly after the mold is adjusted in...

AI Technical Summary

Problems solved by technology

The main disadvantage is that due to the free punching, the operator mainly relies on feeling and experience during the operation, so that the punching of the rough blank cannot be effectively punched, and it is easy to cause eccentric waste products, which in turn leads to frequent skinning at the bottom-cutting and open-width station, and cause folding waste
