A wire fitting crimping tube plastic part

Abstract

The invention relates to a reshaping part for a wire hardware pressing connecting tube. The reshaping part for the wire hardware pressing connecting tube comprises an upper steel channel and a lower steel channel which are vertically welded in an overlapped mode with the upper steel channel matched with the lower steel channel, wherein two reinforcing ribs are arranged on the lower steel channel, the lower steel channel is a U-type steel channel with an opening facing upwards, the two reinforcing ribs are vertically welded to the lower steel channel, a first channel opening and a third channel opening are formed between the two reinforcing ribs and the two sides of the lower steel channel respectively, and a second channel opening is further formed between the two reinforcing ribs and a base plate of the lower steel channel. In the reshaping process, the reshaping part is placed at the position of a lower die of a hydraulic machine in the direction of the pressing connecting tube, the bent part of the wire pressing connecting tube faces upwards, the concave part of the wire pressing connecting tube faces downwards, an upper die of the hydraulic machine is put down, and then the hydraulic machine is started for reshaping. Compared with the prior art, the reshaping part for the wire hardware pressing connecting tube is simple in structure, convenient to construct, capable of not only effectively ensuring that pressing connection of the pressing connecting tube is flat and straight, but also performing correction on a bent pipe, and applicable to reshaping expanded diameter wire hardware pressing connecting tubes or other wire hardware pressing connecting tubes.

Description

technical field [0001] The invention relates to the field of wire crimping technology, in particular to a plastic part for preventing crimping and bending of wire fittings crimping tubes. Background technique [0002] The crimping tube of the 1600 expanded diameter wire fittings is prone to bending during the crimping process. The subjective reasons for this phenomenon: 1) The hydraulic tongs are not placed flat. 2) When the crimping tube is put into the lower steel mold or when the crimping tube is moved during the crimping process, the crimping tube is inconsistent with the axis of the hydraulic pliers. 3) When the crimping tube is put into the steel mold, because the wire is not placed horizontally, an upward torque is generated. When crimping, the crimping tube deviates upward and sideways, causing the core of the crimping tube to be inconsistent with the axis of the hydraulic pliers. The objective reason is that the 1600-diameter expanded wire has a relatively long cr...

AI Technical Summary

Problems solved by technology

Due to the large number of modules, during the movement of the crimping tube from one mold to another, the offset error will be superimposed with the increase of the crimping module, causing the crimping tube to bend

In addition, the diameter of the wire is large, and the torque between the wire and the crimping tube is greater in a non-horizontal state, which will easily cause the fittings to shift during the crimping process, and the probability of bending after crimping the wire clip increases.
