Drawing speed and drawing rhythm control technology aiming at stranded wire relaxation

Abstract

The invention discloses a rhythm and speed control technology for preventing a stranded wire from relaxing due to an inertia effect when the stranded wire is cut, and belongs to the processing field of cord type explosive devices. The technology comprises the following steps of (1) building a stranded wire cutting model; (2) determining undetermined parameters in the stranded wire cutting model through a lot of cutting experiments according to the cutting model; and (3) maintaining a stranded wire relaxation degree within an allowable range, on-line adjusting stranded wire drawing speed and length by a mechanical hand, and achieving an optimal effect. According to the technology provided by the invention, the situation that the stranded wire is relaxed due to the inertia effect after being drawn and cut for multiple times can be remarkably improved; and through building the stranded wire cutting model, the drawing speed and the drawing rhythm of the stranded wire are on-line coordinated by utilizing a functional principal and a rotational inertia concept, and the stranded wire can be effectively prevented from being relaxed by utilizing software, so that the stranded wire in different lengths is quickly and accurately cut, the production efficiency is improved, and the cost is saved.

Description

technical field [0001] The invention relates to a technology for preventing slack in twisted wires by adding a cable-like pyrotechnic device, which reduces the cumulative effect of inertia of the twisted wires by controlling the pulling speed and rhythm of the twisted wires, thereby avoiding slack in the twisted wires. Background technique [0002] Cutting the stranded wire refers to the process of pulling out the required length of the stranded wire by the manipulator, and then cutting it. Generally, there are three types of lengths required: 0.5m, 1m, and 2m. The following problems exist in the cutting process of stranded wire: [0003] In the pulling and cutting process of the twisted wire, after the completion of one pulling and cutting process, the twisted wire will continue to rotate due to inertia; after multiple pulling and cutting actions are completed, due to the accumulation of inertia, the twisted There will be slack in the line, which will affect the follow-up ...
