AI Technical Summary

Technical Problem

During the flat bottom of existing metal detonator shells, it is difficult to ensure the consistency of flatness and dimensions of the bottom of each detonator shell, resulting in unstable product quality and difficult to achieve high-precision positioning and flatness control.

Method used

A metal detonator shell flat bottom mold is designed, using a combined structure of casing and annular clamping sleeve. The casing ensures the position of the detonator shell accurately and firmly fixes and adjusts through the annular clamping sleeve to ensure the accuracy and efficiency of the flat bottom process.

Benefits of technology

By using a combined structure of the sleeve and annular sleeve, the position of the detonator shell in the mold is accurate and the pressure is uniform, and a flatter and even bottom surface is achieved, which improves operating efficiency and product quality stability.

Abstract

The utility model discloses a metal detonator shell flat bottom die which comprises a bottom plate, a sleeve fixing base is arranged above the bottom plate, a sleeve is fixedly arranged above the sleeve fixing base, a fixing clamping base is arranged on the side face of the sleeve fixing base, a fixing bolt is connected to the upper portion of the fixing clamping base in a screwed mode, and the fixing bolt is connected to the lower portion of the fixing clamping base in a screwed mode. A sleeve clamping groove is formed in the side face of the sleeve, a sleeve rod is fixedly arranged on the inner side of the sleeve, and a lower die plate is fixedly arranged above the sleeve rod. According to the utility model, the detonator shell is sleeved by using the sleeve, so that the accurate position of the detonator shell in the mold can be ensured, the deviation or dislocation in the flat bottom process can be avoided, the pressure can be ensured to uniformly act on the bottom of the detonator shell by using the sleeve, the local stress is prevented from being too large or too small, and the smoother and more uniform bottom surface can be obtained.
