A tin wire automatic forming shearing machine and its tin wire shearing method

Abstract

The invention discloses a tin wire fully-automatic forming and shearing machine and a tin wire shearing method thereof. The machine is used for extruding and processing a continuous packaged cylindrical tin wire to form flat tin strips according with welding requirements and having a specific length, and comprises a forming mechanism for extruding the cylindrical tin wire to form the flat tin strips, a driving mechanism for driving the forming mechanism to extrude the tin wire, a feeding mechanism for sending the packaged cylindrical tin wire to the forming mechanism, a cutting mechanism for shearing the extrusion-formed tin strips to form the specific length, and a frame for installing above mechanisms. The machine has the advantages of automatic completion of feeding, forming and cutting of the tin wire, concise structure, and small occupied space, and the tin strips produced by using the tin wire fully-automatic forming and shearing machine have same thickness and consistent length, and are a finished product which can be directly used, so the welding quality and the welding rate are greatly improved, the appearances of welding points are uniform and consistent, and the welded fraction defective is greatly reduced.

Description

technical field [0001] The invention relates to a device for preprocessing tin wire, in particular to an automatic tin wire forming mechanism and a tin wire cutting method for preprocessing tin wire into a shape convenient for welding. Background technique [0002] Existing automotive glass is generally prepared by cooling ordinary glass at high temperature. The windshield used in automobiles is often surrounded by black borders for the purpose of beautifying the glass, and the rear windshield is often printed with heating wires on the glass due to defrosting requirements. The heating device can eliminate frost in the heating area on the outer surface of the glass. Ability. Since tempered glass cannot be reprocessed, in the process of preparing windshield tempered glass, ordinary glass must be wrapped with black borders and printed with heating wires (the ends are equipped with busbars), and then heated for tempering. [0003] The tempered windshield obtained by tempering ...

AI Technical Summary

Problems solved by technology

In the process of welding the electric insert, it is necessary to use tin wire to weld the electric insert on the glass. The supply state of the tin wire is generally a roll of cylindrical tin wire, and the continuous tin wire is in the welding process. It is extremely inconvenient to use. In order to facilitate welding, the current common method is to manually use scissors to cut the tin wire into tin strips with a length of about 1cm. However, it takes 2 to 3 hours to process a roll of tin wire into sections of tin strips. Time-consuming, time-consuming and labor-intensive, and the obtained tin bars are of different lengths, which cannot meet the needs of production. It is also easy to affect the welding quality of the electric plug because the length of the tin bars does not meet the requirements, resulting in a waste of human and material resources.
