Description

Technical Field

[0001] The utility model relates to the technical field of tin material processing, in particular to tin processing wire drawing equipment with a cleaning function. Background Art

[0002] Wire drawing is a metal processing technology. In metal pressure processing, the metal is forced through the die under the action of external force, the metal cross-sectional area is compressed, and the technical processing method of obtaining the required cross-sectional area shape and size is called metal wire drawing technology. The tool that changes its shape and size is called a wire drawing die. The solder wire is composed of tin alloy and additives. The alloy components are divided into tin-lead and lead-free additives that are evenly poured into the middle part of the tin alloy. Different types of solder wires have different additives. The additive part is to improve the auxiliary heat conduction of the solder wire during the welding process, remove oxidation, reduce the surface tension of the material to be welded, remove oil stains on the surface of the material to be welded, and increase the welding area. The characteristic of the solder wire is a tin alloy wire with a certain length and diameter. It can be used with an electric soldering iron or laser in the welding of electronic components.

[0003] Announcement No. CN 211803130 U discloses a wire drawing device for tin wire processing. By setting an adjustment structure, the adjusting knob can be turned to drive the threaded rod to rotate. The threaded rod can be rotated to drive the extrusion block to rotate. The extrusion block moves, so that the movable plate is squeezed and starts to move downward, and finally the tensioning roller can be moved to a suitable position, so that the tensioning roller can be adjusted according to different tin wires, ensuring that the tin wire can be subjected to the most appropriate tensioning force during wire drawing, effectively avoiding the problem of tin wire breakage or uneven stretching diameter during wire drawing. However, the patent still has the following problems in actual use:

[0004] Although the wire drawing device for tin wire processing adjusts the tension of the wire drawing by setting an adjustment structure, thereby avoiding the problem of breakage of the tin wire or uneven stretching diameter during the wire drawing process, the wire drawing device for tin wire processing does not have a relevant cleaning structure to clean the surface of the tin wire. The dust and impurities on the surface of the tin wire will affect the diameter of the tin wire drawing, and will also affect the unevenness of the tin wire. When winding, the uniformity of the winding cannot be guaranteed, thereby affecting the winding length of the tin wire.

[0005] A tin processing wire drawing device with a cleaning function is proposed to solve the above-mentioned problems. Utility Model Content
