Description

Technical Field

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

[0002] In the precise process of welding wire production, every step is crucial, especially the transformation process from tin block melting to the final welding wire forming. This process starts with the heating and melting of tin blocks, followed by the precise addition and mixing of flux (rosin) with the molten tin, and the formation of a preliminary tin bar shape through an extruder. Subsequently, these relatively thick-diameter tin bars need to undergo stretching and thinning to transform into standard welding wires.

[0003] To achieve this complex and delicate production process, modern welding wire manufacturing industries adopt highly integrated tin bar processing equipment. Based on a stable support frame, the core component - an extruder is mounted on it. The extruder is ingeniously designed, not only having a feeding port for easy input of tin blocks, but also having an efficient heating source inside 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 material. To smoothly and stably transport the flux into the extruder, the storage tank is connected to the extruder through a precise connecting pipe and is powered by an external pressure pump.

[0004] However, during the operation of traditional pressure pumps, it may inadvertently compress and inject air containing moisture into the storage tank. Once these moisture enters the flux system, it will directly contaminate the originally pure flux, and then be wrapped inside the tin bar during the extrusion molding process. When the tin bar containing moisture is subsequently stretched and processed into a welding wire, the moisture may cause various adverse consequences, including but not limited to the decline in the surface quality of the welding wire, the weakening of welding performance, and even potential 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, to solve the problems in the above related technologies that external moisture may contaminate the flux, affect the use performance of the subsequent finished welding wire, and pose safety hazards.

[0006] An extrusion molding device for tin bar production provided by this application adopts the following technical solutions:

[0007] An extrusion molding device for tin bar production, including a base platform, on which there is an extrusion machine for extruding tin blocks, a feeding component for feeding tin blocks, and an extrusion component for placing the fed tin blocks into the extrusion machine; on the side of the base platform, there is a storage tank for storing flux and a pressure tank for storing dry air and providing pressure. A feeding pipe for connecting the extrusion machine is fixed on the storage tank, a pressurizing pipe for connecting the storage tank is fixed on the pressure tank, and a control valve is arranged on the pressurizing pipe.

[0008] By adopting the above technical solution, the air that has been filtered is pre-stored in the pressure tank. During the system processing and forming process, the control valve can be activated, so that the flux in the storage tank enters the extrusion machine together under the action of the pressure tank, and finally the molten tin mixed with the flux is extruded and formed together; since the air stored in the pressure tank is dry and filtered air and does not contain moisture, the possibility that external moisture may contaminate the flux and affect the forming quality of the welding wire is reduced.

[0009] Optionally, a first pressure regulating valve is fixed at the end of the pressurizing pipe close to the pressure tank, and a second pressure regulating valve is fixed at the end close to the storage tank. 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.

[0010] 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 pressures in the pressure tank and the storage tank are adjusted, thereby avoiding the reduction of the air pressure in the pressure tank after a period of time and affecting the subsequent feeding of the flux, and improving the use performance of the extrusion molding device.

[0011] Optionally, the feeding component includes a lifting cylinder fixed on the base platform, a lifting plate fixed at the upper end of the lifting cylinder, and a feeding slide rail fixed on the base platform; a limiting groove for placing tin blocks is opened on the lifting plate, the feeding slide rail is arranged obliquely as a whole, and the end of the feeding slide rail close to the lifting plate is the lowest point; when the lifting plate moves up and down, it can coincide with the feeding port of the extrusion machine and the lowest point of the feeding slide rail.

[0012] By adopting the above technical solution, during the feeding process of the tin blocks, multiple tin blocks are pre-placed inside the feeding slide rail, and the tin blocks slide along the feeding slide rail in the direction close to the lifting plate; when the lifting plate moves to the state of coinciding with the lowest point of the feeding slide rail, the tin block on the lowest side of the feeding slide rail slides into the limiting groove, and then the lifting plate is lifted to the position coinciding with the feeding port of the extrusion machine, and then the tin block in the limiting groove is extruded into the extrusion machine through the extrusion component; in this way, the feeding process of the tin blocks is realized, which is convenient for the subsequent melting and extrusion processing of the tin blocks.

[0013] Optionally, a support frame for supporting the storage tank is provided on the side surface of the base platform. A support plate is fixedly provided at the upper end of the support frame, and two mutually staggered and perpendicular support rods are fixedly provided at the lower end of the support frame. A plurality of supports are fixedly provided on the side surface of the support rod away from the support frame.

[0014] By adopting the above technical solution, during the installation of the storage tank, first place the support frame on the ground so that the supports are in contact with the ground, and then place the storage tank on the upper side surface of the support plate, thereby realizing the installation of the storage tank.

[0015] Optionally, a receiving member for supporting the pressure tank is provided on the side surface of the base platform. The receiving member includes a receiving plate and a plurality of limiting rods fixedly provided on the receiving plate. The ends of the plurality of limiting rods away from the receiving plate are jointly fixedly provided with a limiting ring sleeved on the outer periphery of the pressure tank.

[0016] By adopting the above technical solution, during the application of the pressure tank, due to the application setting of the receiving member, the pressure tank can be inserted vertically into the inside of the limiting ring, so that the bottom end of the pressure tank is in contact with the upper side surface of the receiving plate, and the receiving plate is placed on the ground, thereby realizing the support and limitation of the pressure tank.

[0017] Optionally, a plurality of universal wheels are fixedly provided on the bottom side of the receiving plate, and a traction pull rod is hinged on the side edge of the receiving plate. A traction handle is fixedly provided at the end of the traction pull rod away from the receiving plate.

[0018] By adopting the above technical solution, when the position of the pressure tank needs to be moved, the user can drive the movement of the receiving plate by pulling the traction handle and the traction pull rod, which is convenient for moving and adjusting the position of the pressure tank according to actual needs.

[0019] Optionally, an adjusting member is provided above the base platform. The adjusting member includes a first fixing ring and a second fixing ring sleeved on the common outer periphery of a plurality of limiting rods. The first fixing ring is located above the second fixing ring; a first adjusting rod and a second adjusting rod are hinged on the traction pull rod. The other end of the first adjusting rod is hinged to the outer peripheral surface of the first fixing ring, and the other end of the second adjusting rod is hinged to the outer peripheral surface of the second fixing ring; when the traction pull rod rotates, it drives the first fixing ring and the second fixing ring to slide reciprocally along the length direction of the limiting rod.

[0020] By adopting the above technical solution, when the traction pull rod rotates, it drives the first adjusting rod and the second adjusting rod to rotate, and the first adjusting rod and the second adjusting rod respectively drive the first fixing ring and the second fixing ring to move up and down. However, the first fixing ring and the second fixing ring have a limited up and down movement distance, thereby limiting the rotation range of the traction pull rod.

[0022] By adopting the above technical solution, when the first fixing ring and the second fixing ring slide up and down, the outer peripheral surface of the pressure tank can be cleaned by the cleaning cotton, reducing the possibility of external dust or other stains adhering to the outer peripheral surface of the pressure tank; the too-long pressure pipe can be wound inside the relief ring groove, better collecting and arranging the pressure pipe.

[0023] Optionally, a locking plate is hinged to the side surface of the traction pull rod, a locking through hole is formed in the locking plate, a plurality of locking screw holes capable of coinciding with the locking through hole are formed in the first adjusting rod and the second adjusting rod, and a locking screw for passing through the locking through hole and then screwing into the locking screw hole is arranged above the base.

[0024] By adopting the above technical solution, when the traction handle rotates to the vertical state, the locking through hole can coincide with the corresponding locking screw hole; when the traction handle rotates downward to the limit position, the locking through hole can coincide with the corresponding locking screw hole, thereby realizing the locking of the state of the traction pull rod.

[0025] Optionally, a locking block is fixedly arranged on the base, and a locking convex block is fixedly arranged on the locking block; locking notches for placing the locking block are formed in the side surfaces of the first fixing ring and the second fixing ring close to each other, and locking sinking grooves for inserting the locking convex block are formed in the inner wall of the locking notch; the side surfaces of the first fixing ring and the second fixing ring close to each other can abut against and be fixed.

[0026] By adopting the above technical solution, when the traction rod rotates, it will drive the first fixing ring and the second fixing ring to move up and down, and the side surfaces of the first fixing ring and the second fixing ring close to each other can abut against and be locked, so that the locking convex block is inserted into the locking sinking groove, thereby realizing the locking of the installation position of the pressure tank and reducing the possibility of the pressure tank moving and sliding in the natural state during the application of the forming device.

[0027] In summary, the present application includes at least the following beneficial technical effects:

[0028] 1. Since the air stored in the pressure tank is air that has been dried and filtered and does not contain moisture, the possibility that external moisture may contaminate the flux and affect the forming quality of the welding wire is reduced; due to the combined setting of the first pressure regulating valve and the second pressure regulating valve, the air pressures in the pressure tank and the material storage tank are regulated, thereby avoiding the reduction of the air pressure in the pressure tank after a period of time and affecting the subsequent feeding of the flux, and improving the use performance of the extrusion forming device.
