Stamping device for precisely positioning plate half-moon

Abstract

The invention discloses a stamping device for precisely positioning a plate half-moon, and belongs to the technical field of blanking devices. The stamping device comprises a gasket, a driving block,a guide sliding block, a base, a male die, a fixed seat, a mounting block, a guide plate, a sliding block, a rotation stopping key, a rotating shaft pressing block, a sleeve, a rotating shaft mountingseat, a rotating shaft and a positioning sliding block. The guide plate is adopted for guiding, the gap between the guide plate and the guide sliding face is adjusted by additionally arranging the gasket on the back face of the guide plate, the position precision of the mounting block is improved, and therefore the half-moon position precision is improved. In this way, the influence of machiningerrors on the precision of the half-moon position can be compensated for, more accurate installation is achieved, the error value of the half-moon position degree is controlled within plus or minus 0.03 millimeter, the precision is high, the half-moon position adjusting process is not subjected to space limitation, and adjustment is convenient.

Description

technical field [0001] The invention belongs to the technical field of punching devices, and in particular relates to a punching device for precise positioning of half-moon plates. Background technique [0002] In the automatic stamping production of the outer panel of the hood, the stamping process after drawing requires the drawn part to provide an accurate positioning shape (abbreviation: half moon) for the precise positioning of the panel. Half-moon positioning shape. In the traditional blanking process for making half-moon positioning shapes of sheet parts, a via guide is applied between the shape punch and the binder ring of the drawing die. Due to the limitation of processing factors, the shape and position tolerance of the through hole of the pressure plate can only be controlled at a minimum of ±0.05mm, which affects the positioning accuracy of the subsequent sequence. This problem can only be solved by manual modification during the on-site debugging process. [...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a stamping device for finely positioning the half-moon of the plate to solve the technical problems of low accuracy of the traditional device for making the half-moon positioning shape of the plate, and the limited space for adjusting the position of the half-moon.
