Description

Technical Field

[0001] The present application relates to the technical field of tin bar processing, and in particular to an extrusion molding device for tin bar production. Background Art

[0002] In the precision process of solder wire production, every step is crucial, especially the transformation from melting the tin block to the final solder wire. This process starts with the heating and melting of the tin block, followed by the precise addition of flux (rosin) and mixing with the molten tin, which is then formed into a preliminary tin bar through an extruder. Next, these thicker tin bars need to be stretched and refined before they can be transformed into standard solder wire.

[0003] In order to achieve this complex and delicate production process, the modern solder wire manufacturing industry uses highly integrated tin bar processing equipment. The equipment is based on a stable bracket, on which is mounted the core component - the extruder. The extruder is cleverly designed, not only with a feed port for the quick insertion of tin blocks, but also with a built-in efficient heating source to ensure that the tin blocks can be evenly heated and completely melted. At the same time, the powerful power of the extrusion cylinder provides the necessary pressure support for the extrusion molding of the molten tin. In order to smoothly and stably transport the flux into the extruder, the storage tank is connected to the extruder through a precise connecting pipe and powered by an external pressure pump.

[0004] However, during operation, conventional pressure pumps may inadvertently compress air containing moisture and inject it into the storage tank. Once this moisture enters the flux system, it will directly contaminate the originally pure flux and then be wrapped into the tin bar during the extrusion molding process. When the tin bar containing moisture is subsequently stretched into welding wire, the moisture may cause a variety of adverse consequences, including but not limited to the decline in the surface quality of the welding wire, the weakening of welding performance, and even safety hazards during use. Summary of the invention

[0005] The purpose of this application is to provide an extrusion molding device for tin bar production, which solves the problem in the above-mentioned related technology that external moisture may contaminate the flux, affect the performance of subsequent finished welding wire, and pose a safety hazard.

[0006] The present application provides an extrusion molding device for producing tin bars, which adopts the following technical solution: An extrusion molding device for producing tin bars comprises a base, on which are arranged an extruder for extruding tin blocks, a feeding assembly for loading the tin blocks, and an extrusion assembly for placing the loaded tin blocks into the extruder; a storage tank for storing flux and a pressure tank for storing dry air and providing pressure are arranged on the side of the base, a feeding pipe for connecting to the extruder is fixedly arranged on the storage tank, a pressurizing pipe for connecting to the storage tank is fixedly arranged on the pressure tank, and a control valve is arranged on the pressurizing pipe.

[0007] By adopting the above technical scheme, the filtered air is stored in the pressure tank in advance, and during the system processing and molding process, the control valve can be started to allow the flux in the storage tank to enter the extruder together with the pressure tank, and finally the molten tin mixed with the flux is extruded together; because the air stored in the pressure tank is dry and filtered and does not contain moisture, the possibility of external moisture contaminating the flux and affecting the quality of welding wire molding is reduced.

The first pressure regulating valve is used to adjust the air pressure in the pressure tank, and the second pressure regulating valve is used to adjust the air pressure in the storage tank.

[0009] By adopting the above technical solution, due to the coordinated setting of the first pressure regulating valve and the second pressure regulating valve, the air pressure in the pressure tank and the storage tank is adjusted, thereby avoiding the air pressure in the pressure tank from decreasing after a period of time and affecting the subsequent feeding of flux, thereby improving the performance of the extrusion molding device.

[0011] By adopting the above technical scheme, during the tin block feeding process, multiple tin blocks are placed in advance inside the feed slide rail, so that the tin blocks slide along the feed slide rail toward the lifting plate; when the lifting plate moves to a state where it coincides with the lowest point of the feed slide rail, the tin blocks on the lowest side of the feed slide rail slide into the limiting groove, and then the lifting plate is lifted to a position where it coincides with the feed port of the extruder, and then the tin blocks in the limiting groove are extruded into the extruder through the extrusion assembly; thereby, the tin block feeding process is realized, which is convenient for the subsequent melting and extrusion processing of the tin blocks.
