Strip flattening machine

Abstract

The invention relates to a strip flattening machine, belonging to forming equipment for solder brazing materials. The strip flattening machine consists of a front straightening roller electrode device, a flattening roller, a wire feeding wheel, a cutting-off device, a rear straightening roller electrode device and a transformer, wherein the front straightening roller electrode device and the rear straightening roller electrode device which are used for heating and straightening, the flattening roller for rolling an alloy wire to be flatten, the wire feeding wheel and the cutting-off device for cutting the flattened alloy wire are sequentially arranged on an advancing path of the alloy wire; and the front straightening roller electrode device and the rear straightening roller electrode device are connected with a heating electrode and the transformer. The invention has the advantages of reasonable structural design, high production efficiency, stable quality of products, easiness for control and durability.

Description

technical field [0001] The invention relates to a flattening machine, which belongs to brazing material forming equipment. Background technique [0002] The flattening machine is a kind of forming equipment in the flattening process of the non-ferrous metal rolling industry. It is widely used in the processing of brazing materials. Its working principle is: first, the disc-shaped alloy wire is heated by resistance to make it After softening, the bent wire is straightened by the straightening wheel, and then sent to the flattening device. After adjusting the pressing amount of the roller, after reaching the specified size, it is sent to the cutting device under the traction of the wire feeding wheel. Periodic cutting action is required for the length, and finally the strip-shaped flat material with the length, width and thickness up to standard. At present, the flattening and cutting machines on the market adopt the process of heating, straightening, flattening and cutting t...

AI Technical Summary

Problems solved by technology

At present, the flattening and cutting machines on the market adopt the process of heating, straightening, flattening and cutting to achieve the purpose of flattening and cutting. However, due to the use of box rolls, the rolls cannot dissipate heat in time during the flattening process, resulting in bearings Or the copper sleeve is often stuck, which greatly affects the production efficiency, and the cutting device adopts the reciprocating movement of the fixed-length movable device, and uses the signal of the proximity switch to control the punching and cutting of the punching machine. The failure of the proximity switch or the unbalanced and loose fixture will immediately cause wire The material is bent, curled and punched out, resulting in low efficiency and unstable product quality of traditional flattening machines
