Multiple-tungsten-wire truing device

Abstract

The invention provides a multi-tungsten wire shaping device, which includes: at least four sets of retractable wheels, each set of retractable wheels includes a wire unwinding wheel for rolling the tungsten wire to be shaped and a winding wheel for the tungsten wire after shaping. Winding wheel; a flame device, the wire unwinding wheel of each group of retracting and unwinding wheels is arranged next to the inlet end of the flame device, and the wire winding wheel of each group of retracting and releasing wheels is arranged beside the outlet end of the flame device, The tungsten wire pulled out from the wire reel in the unwinding wheel all passes through the flame device and is convoluted on the wire reel for heat treatment and shaping of the tungsten wire to be shaped; a motor; a reduction box whose input shaft is connected to the motor; and The transmission mechanism is connected between the output shaft of the reduction box and the winding wheels of each set of retractable and unwinding wheels, so as to drive the winding wheels of all sets of retracting and unwinding wheels to rotate simultaneously. Beneficial effects of the present invention: Realize simultaneous shaping of more than four tungsten wires.

Description

technical field [0001] The invention relates to tungsten wire manufacturing equipment, in particular to a multi-tungsten wire shaping device. Background technique [0002] In the tungsten wire preparation process, firstly, two semi-finished tungsten wires need to be twisted into a twist-shaped finished tungsten wire. This process needs to be realized by a wire winding machine; The semi-finished tungsten wires are not glued together, and they are still independent of each other. Therefore, after the wire winding work, the finished tungsten wire needs to pass through a flame device with a temperature of 700°C to 800°C to fix the finished tungsten wire. A tungsten wire shaping device is used to achieve this step. [0003] In the prior art, the tungsten wire shaping device includes a flame device. The inlet end of the flame device is provided with a wire-feeding wheel, and the outlet end of the flame device is provided with a winding wheel. After the tungsten wire is released f...

Problems solved by technology

The problem that this device exists is: 1) in the prior art, there is only one wire reel and wire reel, so only one tungsten wire can be pulled between them, so that the whole shaping process is carried out at a slow speed, which cannot meet industrialization requirements. Rapid production needs; 2) Manually turn the winding wheel to complete the tungsten wire retraction, which is time-consuming and laborious, and manual operation does not guarantee that the speed of each section passing through the flame device is the same, so the same tungsten wire has different heat treatment effects for each section, which cannot meet the requirements. Uniform shaping effect requirements
