High-precision punching mold of nut plate

Abstract

The invention relates to a high-precision punching mold of a nut plate. The high-precision punching mold comprises a lower mold plate, an upper mold base and a lower mold base, wherein the upper end of the lower mold plate is connected with the lower mold base through a foot pad, a cushion block is installed at the upper end of the lower mold base, a lower fixing plate is installed at the upper end of the cushion block, a pre-punching fixing sleeve, a deburring fixing sleeve, a chamfering inner angle floating sleeve and a fine punching hole fixing sleeve are sequentially arranged from left toright on the lower fixing plate, an upper fixing plate is installed at the lower end of the upper mold base, a plurality of punches are fixedly arranged at the lower end of the upper fixing plate, a material pressing plate connected with an upper part nitrogen spring in the upper mold base is arranged below the upper fixing plate, a material discharging plate connected with the chamfering inner angle floating sleeve is arranged above the lower fixing plate, a lower part nitrogen spring is installed on the upper side of the lower mold plate, the upper end of the lower part nitrogen spring is connected with a top plate, and the upper side of the top plate is vertically provided with a floating ejector rod, wherein the upper end of the floating ejector rod abuts against the lower end of the chamfering inner angle floating sleeve. According to the mold, the structure is reasonable, the punching is free of burrs, the precision is high, and the demoulding is rapid and accurate.

Description

technical field [0001] The invention relates to the field of punching dies, in particular to a high-precision punching die for a nut plate. Background technique [0002] The punching of plates is now mostly realized by stamping dies. The process of the current continuous punching die is relatively simple, and the punched holes are likely to have burrs, and it is difficult to form chamfers, and the thickness of the two sides is likely to be different, resulting in poor accuracy. High, and often scratches the mold during demoulding. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-precision punching die for a nut plate, which has a reasonable structure, no burrs in the punching, high precision, and fast and accurate demoulding. [0004] The technical solution adopted by the present invention to solve its technical problems is: provide a high-precision punching die for nut plates, including a lower template, ...
