Stretching device and method for silicon bronze welding wire production and processing

Abstract

The invention discloses a stretching device and method for silicon bronze welding wire production and processing, and belongs to the technical field of silicon bronze welding wire stretching devices. The stretching device comprises a preheating mechanism, a stretching machine, a cooling machine and a winding machine. When the welding wire is stretched every time, the preheating mechanism is used for conducting waste heat treatment on the welding wire, so that stretching of the welding wire is more stable and smoother, after stretching is conducted for a period of time, a cutting mechanism is used for cutting off and removing redundant waste residues accumulated on the left side of a thickness control plate, interference between the accumulated waste residues and the welding wire is avoided, The accumulated waste residues not only can lead to difficulty in pulling of the stretching machine, but also can be in contact and interaction with subsequent welding wires, so that scratches are generated on the surfaces of the stretched welding wires, the quality of the welding wires is reduced, and the welding wires are not easily produced, the cutting mechanism cuts off and takes out the accumulated waste residues from time to time, so that the influence of the waste residues on the welding wires is avoided; and stretching processing of the welding wire is facilitated.

Description

technical field [0001] The invention relates to the technical field of silicon bronze welding wire stretching devices, in particular to a stretching device and method for silicon bronze welding wire production and processing. Background technique [0002] Silicon bronze welding wire has a large demand in domestic and foreign markets, especially in the fields of automobile, military industry, chemical industry, shipbuilding, etc. Silicon bronze welding wire is widely used due to its low melting point, good welding performance and beautiful weld seam. Welding of automobile body surfaces. [0003] In the preparation process of the existing silicon bronze welding wire, it is necessary to draw the crude silicon bronze welding wire, but because the silicon bronze welding wire is in the wire drawing process, the direct cold drawing of the welding wire is not conducive to forming a fine welding wire, and the welding wire is in the drawing process. In the welding wire and wire drawi...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of stretching device and method for the production and processing of silicon bronze welding wire, in order to solve the above-mentioned background technology, in the preparation process of existing silicon bronze welding wire, it is necessary to draw the rough silicon bronze welding wire, However, during the drawing process of silicon bronze welding wire, direct cold drawing of the welding wire is not conducive to the formation of fine welding wire, and during the drawing process of the welding wire, material accumulation is easy to form between the welding wire and the drawing wire, and the accumulated excess material will not only affect the quality of the drawn welding wire The size of the hollowing, and it will also affect the welding wire, resulting in scratches on the surface of the welding wire, etc., reducing the quality of the welding wire
