Production technology of rigid fuse

Abstract

The invention relates to the manufacturing technique for detonators, especially the process for preparing rigid igniting head which comprises the following steps, pressing comb teeth, injection molding, shaping, soldering bridge wires, automatically dipping powder, drying the igniting heads and soldering leg wires. The process can realize production automation, increased production efficiency, and guaranteed quality of products.

Description

technical field

[0001] The invention belongs to the production process of a detonator, in particular to the production process of a rigid drug head. technical background

[0002] The traditional detonator ignition charge is elastic, that is, the end of the wire is used as an electrode to connect with the bridge wire, and then the twisted wire is fixed with a plastic fixing plug. Due to the unreliable fixing of the wire, the wire is still easy to move in the fixing plug, so in the process of packaging, welding, dipping, transportation, etc., if it is slightly squeezed, the bridge wire is easy to break, and the entire drug head becomes a waste product ; Many processes in the existing production technology need to be manually operated, which has caused the problems of low production efficiency and difficult quality assurance.
