Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing:

[0018] Such as figure 2 , image 3 As shown, the modified strengthening device of the present invention includes a friction wheel set and a stretching wheel set. The friction wheel set and the stretching wheel are assembled on the frame 1 and driven by a transmission device 2. The friction wheel set consists of a guide wheel 3, a friction wheel The wheel 4 and the pressing wheel 6 are composed of the guide wheel 3 before the friction wheel 4, the friction wheel 4 is tangent to the pressing wheel 6, the temperature regulating water tank 17 is installed in front of the friction wheel group, and two groups of pulleys are installed behind the friction wheel group. The stretching wheel set, the first stretching wheel set is composed of rollers 5 and 7, the second stretching wheel set is composed of rollers 9, 10 and 11, the stretching wheel 5 of the first stretching wheel set a...

Abstract

The present invention relates to detonating tube production process and apparatus in explosion technology. The detonating tube modifying process in a modifying intensifier includes the following steps: properly cooling the detonating tube to 2-30 deg.c; compacting and stretching cooled detonating tube with one group of friction wheels and stretching wheels; heating the detonating tube surface under stretching at 100-500 deg.c; and re-cooling to 2-30 deg.c and stetching. The said process can improve the molecule orientation of detonating plastic tube and raise the tensile strength and oil resistance, and the present invention makes it possible to produce detonating tube of high strength in low cost.

Description

technical field [0001] The invention relates to a production process and equipment for a detonator in the technical field of blasting, in particular to a detonator modification process and a modification enhancement device. Background technique [0002] Detonation tube is a plastic hose used to transmit detonation signals. The tube body is single-layer or double-layer plastic. The outer diameter of the tube is about 3mm, the inner diameter is about 1.3mm, and the inner wall is coated with explosives. The key component of the nonel has long been widely used at home and abroad. The single-layer detonators made of polyethylene plastic currently occupy a major share of the detonator market because of their simple manufacture and low price. The nonel tube that existing low-density polyethylene plastics is made, its production method is that after the nonel tube comes out from the extrusion die mouth, it is made by cooling and setting. Due to direct cooli...
