Wire cutting and stripping method and mechanism

Abstract

The invention provides a method and a device for peeling, trimming and stripping conducting wires while the conducting wires are wound at the waist parts of wire clusters with high efficiency, simple structure and low cost. A trimming and stripping mechanism comprises an upper rotating wheel and a lower rotating wheel which synchronously rotate; the upper rotating wheel and the lower rotating wheel are provided with an upper rotating shaft and a lower rotating shaft; the end parts of the upper rotating shaft and the lower rotating shaft are connected with an upper wrapping post and a lower wrapping post; the upper rotating shaft and the lower rotating shaft are connected with a turnover mechanism; a trimming and stripping cutter is arranged between the upper rotating wheel and the lower rotating wheel; after the wire clusters are wound on a pair of upper and lower wrapping posts, the upper rotating wheel and the lower rotating wheel synchronously rotate for 180 degrees, and the conducting wires at the rear ends of the wire clusters pass through a knife edge; the trimming and stripping cutter is closed, wire sheathes are cut by a left stripping knife and a right stripping knife, and meanwhile, the conducting wires are cut by a trimming knife; a pair of opposite upper and lower rotating shafts synchronously rotates, so as to drive the wrapping posts and the wire clusters to rotate, multiple loops of conducting wires are wound at the waist parts of two wire clusters to form a wire bundle.

Description

technical field [0001] The invention relates to a wire cutting and stripping method and mechanism. Background technique [0002] The domestic process technology and automation level of the nonel nonel industry used in civil blasting equipment is relatively low. For more than ten years, the domestic nonel industry has adopted labor-intensive methods for detonating off-line and manual operation. The main process method, the labor intensity is particularly large, the production efficiency is very low, and the cost is high, which has seriously affected the popularization and utilization of this technology and the market share. [0003] Later, a winding machine (winding mechanism) with a higher degree of automation appeared. It can be used to complete the winding of "8" shape, "O" shape, □ shape, △ shape and other wire handles. The winding step is that the planar link mechanism drives the traction tube used to pass through the wire to move, wind the wire on the winding post to ...

AI Technical Summary

Problems solved by technology

In this wire stripping method, the wires can be cut and stripped after winding multiple turns of wires around the waist of the wire harness to form a wire handle, which is inefficient.

The corresponding wire winding mechanism, wire cutting mechanism and stripping mechanism (including the wire cutter for cutting the wire sheath or the heating device for heating and melting the wire sheath, and the external power device for pulling the wire sheath) are very complicated and costly.
