Description

Technical Field

[0001] This utility model relates to the field of brass solder production technology, and in particular to a stretching device for brass solder production. Background Technology

[0002] As is well known, welding wire is a metal wire used as filler metal or as a conductor for welding. Welding wire made of iron-brass material is called iron-brass welding wire. Welding wire is a type of wire that is produced by multiple stretching passes to create wires of various specifications.

[0003] However, the welding wire is subjected to extrusion during the stretching process, making heat dissipation crucial. Therefore, water-based lubricant is used as a heat dissipation and lubrication material during the stretching process, ensuring that the welding wire is immersed in the water-based lubricant. However, the fluid-blocking structures at both ends, such as guide grooves, designed to control lubricant loss, passively restrict the welding wire path, causing it to deviate from the die axis. This can easily create an angle between the welding wire and the stretching die, resulting in poor quality of the stretched welding wire. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where fluid-blocking structures, such as guide grooves, designed at both ends of the equipment to control lubricant loss passively restrict the welding wire path, causing it to deviate from the mold axis. This results in an angle easily forming between the welding wire and the stretching mold, leading to poor quality of the welding wire stretching. Therefore, this invention proposes a stretching device for brass solder production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Design a stretching device for brass solder production, including a machine body, a fixed base connected to the bottom of the machine body, winding components on both sides of the top of the fixed base, a stretching die assembly in the middle of the machine body, connecting seats on both sides of the top of the machine body, guide rollers rotatably mounted on both connecting seats, fixed beams connected to both sides of the machine body of the stretching die assembly, first guide wheels connected to the bottom of both fixed beams, the outer sides of the bottom of the two first guide wheels guiding the stretching die assembly, and an anti-deviation mechanism on one of the fixed beams for guiding the welding wire into the stretching die assembly at a predetermined angle.

[0006] Preferably, the two fixed beams and the two connecting seats are arranged symmetrically around the stretching die assembly.

[0007] Preferably, the anti-deviation mechanism includes a connecting frame fixed on a fixed beam, the extension direction of the connecting frame being perpendicular to the axial direction of the first guide wheel, an adjustment mechanism being provided on the connecting frame, and the anti-deviation mechanism also includes a pair of second guide wheels, one of which is fixed on the fixed beam, and the other of which is connected to the connecting frame through the adjustment mechanism.

[0008] Preferably, the adjustment mechanism includes a threaded rod threadedly connected to a connecting frame, a guide groove provided on the inner side of the connecting frame, one end of the threaded rod being connected to the wheel frame of a movably arranged second guide wheel via a bearing, a long rod being fixedly connected to the wheel frame of the second guide wheel, and one end of the long rod being slidably disposed in the guide groove.

[0009] Preferably, a rotating block is installed on the outer side of the threaded rod, and the outer side of the rotating block is provided with anti-slip texture.

[0010] Preferably, there are two guide grooves and two long rods, and the two long rods and guide grooves are symmetrically arranged around the movable second guide wheel.

[0011] Preferably, the threaded surface of the threaded rod, the surface of the long rod, and the sliding contact surface of the guide groove are all provided with a wear-resistant coating.

[0012] Preferably, the connecting seat is provided with a lifting component, the actuating end of the lifting component is connected to a cleaning roller, the roller surface of the cleaning roller is arranged opposite to the roller surface of the guide roller, and the vertical projection of the cleaning roller is located on the guide roller.

[0013] The stretching device for brass solder production proposed in this utility model has the following advantages: 1. During the stretching process, the welding wire passes sequentially through the guide channel formed between the guide roller and the pair of second guide rollers on this side, and then passes through the first guide roller on this side. Subsequently, the welding wire passes through the stretching die assembly and is sequentially guided to the first guide roller and guide roller on the other side, and finally reaches another winding assembly. This makes it less likely for the welding wire to form a non-perpendicular angle with the die opening of the stretching die assembly, thereby greatly improving the stability of the stretching process.

[0014] 2. The threaded rod moves the movable second guide wheel within the connecting frame, increasing the distance between the two second guide wheels. This allows welding wires of different diameters to be guided effectively through the two second guide wheels, thus increasing the practicality of the device.

[0015] 3. The welding wire on the guide roller is cleaned by the cleaning roller, so that the water-based lubricant content on the surface of the welding wire is very low during the storage process after stretching, thus making it less likely for water droplets to fall off the stored welding wire.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-4 A stretching device for brass solder production includes a body 1, a fixed base 2 fixedly connected to the bottom of the body 1, a winding assembly 3 fixedly installed on both sides of the top of the fixed base 2, a stretching die assembly 4 disposed in the middle of the interior of the body 1, a connecting base 5 fixedly connected to both sides of the top of the body 1, a guide roller 6 rotatably disposed on both connecting bases 5, a fixed beam 7 fixedly connected to both sides of the body 1, a first guide wheel 8 connected to the bottom of both fixed beams 7, the outer side of the bottom of the two first guide wheels 8 guides the stretching die assembly 4, and an anti-deviation mechanism is disposed on one of the fixed beams 7 to guide the welding wire into the stretching die assembly 4 at a predetermined angle. The anti-deviation mechanism includes a connecting frame 9 fixed on the fixed beam 7. The extension direction of the connecting frame 9 is perpendicular to the axis of the first guide wheel 8. An adjustment mechanism is provided on the connecting frame 9. The anti-deviation mechanism also includes a pair of second guide wheels 10, one of which is fixed on the fixed beam 7, and the other is connected to the connecting frame 9 through the adjustment mechanism.

[0023] Operating Procedure: After connecting the external cooling mechanism to the machine body 1, inject water-based lubricant into the machine body. Securely mount the welding wire coil to be processed onto the winding assembly 3 on one side, and manually lead out the welding wire end. Pass it sequentially through the guide channel formed between the guide roller 6 and the paired second guide rollers 10 on that side, and then through the first guide roller 8 on that side. Subsequently, guide the welding wire through the stretching die assembly 4, and sequentially guide it to the first guide roller 8 and guide roller 6 on the other side, finally reaching another winding assembly 3. After threading is complete, simultaneously and slowly start the winding assemblies 3 on both sides, allowing the welding wire to begin moving smoothly under tension. During the stretching process, the welding wire is less likely to form a non-perpendicular angle with the die opening of the stretching die assembly 4, thus greatly improving the stability of the stretching process. Moreover, the welding wire is immersed in water-based lubricant during the stretching process, allowing the heat generated during the stretching process to be carried away, reducing the probability of abnormal deformation during the stretching process, thereby improving the quality of the stretched welding wire.

[0024] Example 2: In Example 1, the center distance between the two first guide wheels 10 is fixed. When processing welding wires of different specifications, the fixed distance can lead to partial mismatches, making it difficult for thicker welding wires to pass through. Based on Example 1, optimizations are made, referencing... Figure 1-4 The adjustment mechanism includes a threaded rod 11 threadedly connected to a connecting frame 9. A guide groove 13 is provided on the inner side of the connecting frame 9. One end of the threaded rod 11 is connected to the wheel frame of a movable second guide wheel 10 via a bearing. A long rod 12 is fixedly connected to the wheel frame of the second guide wheel 10. One end of the long rod 12 is slidably disposed in the guide groove 13. A rotating block 14 is fixedly installed on the outer side of the threaded rod 11. An anti-slip guide groove 13 is provided on the outer side of the rotating block 14. There are two long rods 12. The two long rods 12 and the guide groove 13 are symmetrically arranged around the movable second guide wheel 10.

[0025] By using a torque wrench to rotate the rotating block 14, the rotating block 14 rotates the threaded rod 11, and the threaded rod 11 moves the movable second guide wheel 10 within the connecting frame 9, increasing the distance between the two second guide wheels 10. This allows welding wires of different diameters to be guided well by the two second guide wheels 10, thereby increasing the practicality of the device. Combined with the symmetrical structure, the workload can be distributed, making the force acting on the threaded rod 11, long rod 12 and other transmission components more even, thereby reducing uneven wear and making the device operate stably.

[0026] Example 3: Although symmetrical arrangement reduces uneven wear in Example 2, the long rod 12 and guide groove 13 are in sliding friction contact, which is prone to wear after long-term operation, increasing the clearance between them and affecting the fit. Based on Example 1, optimizations are made, referring to... Figure 1-4Two fixed beams 7 and two connecting seats 5 are symmetrically arranged around the stretching die assembly 4, making it easier to control the stroke before and after the welding wire is stretched, and avoiding excessive stroke on one side. The threaded surface of the threaded rod 11, the surface of the long rod 12, and the sliding contact surface of the guide groove 13 are all provided with a wear-resistant coating. The wear-resistant coating is formed by spraying nickel-based alloy powder, which makes the surfaces of the threaded rod 11, the long rod 12, and the guide groove 13 more wear-resistant, thereby reducing wear during operation and improving the practicality of the device.

[0027] Example 4: In Example 1, after the welding wire is stretched, during the winding process, the welding wire is bent upwards at an angle. The water-based lubricant on the surface of the welding wire will largely return to the machine body 1, and some water-based lubricant will remain on the surface of the welding wire. This allows for optimization of the welding wire based on Example 1. (Refer to...) Figure 1-2 A lifting assembly 15 is provided on the connecting seat 5. The actuating end of the lifting assembly 15 is connected to a cleaning roller 16. The roller surface of the cleaning roller 16 is arranged opposite to the roller surface of the guide roller 6, and the vertical projection of the cleaning roller 16 is located on the guide roller 6. The cleaning roller 16 cleans the welding wire on the guide roller 6, so that the water-based lubricant content on the surface of the stretched welding wire is very low during the storage process, thus making it less likely for water droplets to fall from the stored welding wire.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
