Description

Line former and one-time forming module of polygonal bending angle Technical Field The invention relates to the technical field of wire rod forming, in particular to a wire forming device and a multi-angle one-time forming module. Background In the manufacture of electrical equipment such as motors and transformers, wire windings are widely used because of their advantages such as high space utilization and good electrical conductivity. Such windings are typically formed from flat copper or aluminum wire by precision bending to form a specific spatial shape and angle, such as a U-or I-wire. Aiming at the U-shaped line, the top structure of the U-shaped line is mainly divided into two types: One is a basic angular structure (shown as a U1 position in the figure) formed by two straight sides and one inner angle, and the other is a polygonal structure (shown as a U1 position in the figure) similar to an isosceles trapezoid formed by three straight sides and two inner angles. For the second type of U-shaped line (namely an approximate isosceles trapezoid structure formed by three sections of straight edges and two inner angles), bending processing is mainly performed in a sequential forming mode at present. The method generally needs to gradually complete bending at all angles through a plurality of single-step bending procedures or changing different dies. However, this process has the following significant limitations: 1. the production efficiency is low, and the production process is complex and the beat is long due to the multi-operation; 2. In the continuous bending process, the wire rod needs to be positioned and clamped for many times, so that accumulated errors are easy to generate, the critical dimensions such as bending angles, spacing and the like are influenced, and the consistency of products is reduced; 3. The molding difficulty is high, and the middle line segment is generally short, so that the positioning and the control are difficult in successive bending, and the processing difficulty is further increased.
