Full-automatic straight welding wire machining production line

Abstract

The invention discloses a full-automatic straight welding wire machining production line. The full-automatic straight welding wire machining production line comprises a paying-off machine, a wheel-type straightener, a compressing skiving unit, a traction coiling block, a wire feeding straightening system and a flying shear number pressing machine, wherein the paying-off machine, the wheel-type straightener, the compressing skiving unit, the traction coiling block, the wire feeding straightening system and the flying shear number pressing machine are arranged in sequence in a spaced mode in the horizontal direction. The full-automatic straight welding wire machining production line has the advantage of achieving continuous machining of skiving, straightening, cutting-off and number marking of metal straight welding wires. Due to the fact that the wire feeding straightening system comprises two set of wire feeding mechanisms, and a pressing wheel straightening mechanism is arranged between the two sets of the wire feeding mechanisms, a straightened metal straight welding wire can be kept to be in a linear state all the time. According to each wire feeding mechanism, due to the facts that an upper synchronous track and a lower synchronous track are adopted to carry out pneumatic opening and pneumatic closing through a power air cylinder arranged on a lower sliding plate, and two rows of synchronous pressing wheels are adopted on a wire pressing position to carry out tight pressing through the synchronous tracks, the contact area between a wire and the wire pressing position can be increased, and the full-automatic straight welding wire machining production line is beneficial to keeping the linear characteristic of the wire. Due to the fact that the synchronous tracks are used for feeding the wire in a clamping mode, the number of scratches on the surface of the wire is reduced, quality of the surface of the wire is effectively ensured, and the follow-up cleaning working procedure and the follow-up polishing working procedure of the wire are omitted.

Description

Technical field [0001] The invention relates to the processing and production of metal welding wires, in particular to a full-automatic straight welding wire processing production line. Background technique: [0002] Metal straight wire, such as aluminum alloy straight wire, is mostly used for welding high-speed rail car bodies, aviation, ships, handicrafts and other fields. In the drawing process of welding wire, one or more annealing is required, and there must be an oxide film and oil stain on its surface. This not only affects the appearance quality of the welding wire, but also directly affects the welding quality. Defects such as pores or oxidized inclusions appear at the weld, resulting in the deterioration of the structure at the weld and the reduction of mechanical properties. [0003] At present, the oxide film and oil dirt on the surface of the straight wire are mostly removed by chemical treatment processes (alkali washing, acid washing). There are many pits on the su...

AI Technical Summary

Problems solved by technology

The shortcomings of its existence are mainly as follows: 1. Low production efficiency, high labor intensity, and cumbersome procedures

2. In order to remove the dirt and grease on the surface of the welding wire, chemical cleaning is required, the labor intensity of the workers is high, the efficiency is low, the working environment is poor, and the environment is seriously polluted

3. The rotating straightening process is very easy to form spiral lines on the surface of the straight welding wire, which affects the brightness and quality of the wire surface
