Tension spring type steel plate locating device for automobile steel plate drawing mould

Abstract

A tension spring type steel plate locating device for automobile steel plate drawing mould is composed of a pedestal, two location plates, a retainer level, a pin roll, a cotter and a tension spring;wherein the pedestal is provided with a bolt through hole fixed with the mould; the two location plates are arranged in parallel and respectively fixed with the pedestal, the location plate is provided with a pin roll hole, the charge level of the location plate is provided with inclination, and the location plate is provided with a tension spring pin; the retainer level is arranged in the middleof the two location plates, the retainer level is provided with a pin roll hole, the pin roll penetrating the two location plates and the pin roll hole on the retainer level is connected with the twolocation plates, the retainer lever rotates around the pin roll, and one end of the retainer level is provided with a tension spring pin; and the two ends of the tension spring are respectively fixedwith the location plate and the tension spring pin on the retainer level. The invention has the advantages that: structure is simple, practicability is strong, the retainer lever can ensure the steelplate to be in steady location when being placed into the mould, and the location plate can ensure the steel plate to be reliably positioned in the compression molding process, so that plates can notstir and product quality after stamping is ensured.

Description

(1) Technical field [0001] The invention relates to an automobile mold positioning device, in particular to a tension spring type steel plate positioning device used for an automobile steel plate drawing die. (2) Background technology [0002] In the drawing process of stamping parts, conventional positioning standard parts are generally used for the initial positioning of sheets, but in the drawing process of parts with large surface fluctuations, due to the failure of conventional positioning methods, it is easy to cause unstable positioning and thus The movement of the sheet will affect the drawing quality on the one hand; on the other hand, it will cause damage to the surface of the workpiece, resulting in an increase in the scrap rate. At present, the selection of positioning methods in the drawing process of large undulating parts has been perplexing designers. How to effectively locate when conventional positioning parts fail to locate is a problem worth thinking abou...
