Description

Technical Field

[0001] This utility model relates to the field of welding wire processing technology, specifically to a wire take-up protection device for welding wire production. Background Technology

[0002] Flux-cored welding wire, also known as powder-cored welding wire or tubular welding wire, is made of materials with good plasticity, such as low-carbon steel or low-alloy steel. The manufacturing process involves first rolling a steel strip into a U-shaped cross-section, then filling the U-shaped steel strip with a pre-mixed amount of welding powder, pressing it tightly with a rolling mill, and finally drawing it into flux-cored welding wires of different specifications.

[0003] After the flux-cored welding wire is processed, it is fed into the wire guide by a wire guide machine for winding and coiling, which facilitates subsequent packaging and transportation. To ensure the stability of the winding, the welding wire is under tension between the wire guide machine and the wire guide machine, and is subjected to a large force. If the welding wire breaks due to excessive force, the broken wire will rebound at high speed and may injure nearby operators, causing injury and jeopardizing safe production in the workshop. In addition, because the welding wire is thin, it is not easy to observe. If workshop personnel do not pay attention and touch the welding wire during high-speed winding, they may be injured by the wire, causing a safety accident. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a wire winding protection device for welding wire production. It utilizes a movable sleeve to cover the welding wire, and the movable sleeve, in conjunction with the rotating support, moves synchronously with the welding wire during winding without interfering with the wire's movement. This significantly improves the safety of welding wire winding and reduces the occurrence of safety accidents.

[0005] This utility model is achieved through the following technical solution:

[0006] A wire take-up protection device for welding wire production is provided, which is installed between a wire guide and a wire feeder. It includes a movable sleeve that is sleeved on the welding wire between the two. One end of the movable sleeve is mounted on a movable seat of the wire feeder via a connecting seat, and the other end of the movable sleeve is movably mounted on the frame of the wire guide via a rotating support. The rotating support includes a support platform fixed on the frame of the wire guide, which is located directly below the welding wire. A rotating seat is rotatably mounted on the support platform via a bearing seat and a bearing. A positioning ring sleeved on the end of the movable sleeve is connected to the rotating seat. The diameter of the positioning ring is larger than the outer diameter of the movable sleeve.

[0007] Preferably, the movable sleeve has a long opening along its length to facilitate threading.

[0008] Furthermore, the inner diameter of the movable sleeve is larger than the diameter of the welding wire.

[0009] The inner diameter of the movable sleeve is larger than the diameter of the welding wire, so that the welding wire and the inner cavity of the movable sleeve form a buffer cavity. If the welding wire breaks, the welding wire can release stress in the buffer cavity and the movable sleeve can absorb the breaking force of the welding wire, thereby reducing the injury to personnel when the welding wire breaks.

[0010] Preferably, the outer peripheral wall of the movable sleeve is provided with a glossy coating.

[0011] By applying a glossy coating to the outer wall of the movable sleeve, it can serve as a warning, making it easier for workshop personnel to notice and reducing the occurrence of injuries due to accidental contact.

[0012] The beneficial effects of this utility model are:

[0013] This utility model's wire take-up protection device utilizes a movable sleeve covering the outer circumference of the welding wire. One end of the movable sleeve is connected to the movable seat of the wire guide via a connecting seat, while the other end is connected to the frame of the wire guide machine in conjunction with a rotating support. When the welding wire is taken up, the movable seat moves laterally back and forth, causing the welding wire to move laterally back and forth synchronously. As the welding wire moves, it applies force to the movable sleeve, and the other end of the movable sleeve applies force to the positioning ring. The positioning ring rotates synchronously on the support platform via a rotating seat, allowing the movable sleeve to move synchronously with the welding wire without interference between them. The outer circumference of the welding wire is always covered by the movable sleeve. Even if the welding wire breaks, the movable sleeve can absorb the breaking force, thereby ensuring that the broken welding wire will not cause injury to personnel, reducing the occurrence of safety accidents, and improving workshop safety.

[0020] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0021] A wire take-up protection device for welding wire production is installed between the wire guide 6 and the wire feeder 1. It includes a movable sleeve 4 fitted onto the welding wire 3 between the two. The inner diameter of the movable sleeve 4 is larger than the diameter of the welding wire 3. The movable sleeve 4 can be made of steel pipe. For ease of installation, the movable sleeve 4 has a long slot 11 along its length for easy wire threading. The welding wire 3 can directly enter the movable sleeve 4 through the long slot 11, eliminating the need to enter from one end and exit from the other, greatly improving installation convenience. In this embodiment, the outer wall of the movable sleeve 4 is coated with a yellow coating, which is highly visible, improving visibility and making it easy for workshop personnel to identify, reducing the risk of accidental contact and enhancing safety.

[0022] One end of the movable sleeve 4 is mounted on the movable seat 2 of the wire guide 1 via the connecting seat 9, and the other end of the movable sleeve 4 is movably mounted on the frame of the wire guide machine 6 via the rotating support. The rotating support includes a support platform 7 fixed on the frame of the wire guide machine 6. The support platform 7 is located directly below the welding wire 3. A rotating seat 10 is rotatably mounted on the support platform 7 via a bearing seat 12 and a bearing 8. A positioning ring 5 is connected to the rotating seat 10 and sleeved on the end of the movable sleeve 4. The diameter of the positioning ring 5 is larger than the outer diameter of the movable sleeve 4.

[0023] The working principle of this utility model:

[0024] The wire take-up protection device of this utility model is installed on the welding wire 3 between the wire guide 6 and the wire feeder 1. The welding wire 3 enters the inner cavity of the movable sleeve 4 through the elongated through-hole 11 on the movable sleeve 4 for easy installation and disassembly. After the wire feeder 1 is started, the movable seat 2 on the wire feeder 1 will move laterally back and forth to guide the welding wire 3 to move and be evenly wound. At this time, the movable seat 2 will drive the connecting seat 9 and the movable sleeve 4 on the connecting seat 9 to move synchronously. The end of the welding wire 3 that passes through the wire guide 6 remains in a stable position. The welding wire 3 swings laterally back and forth with the rotating support part on the frame of the wire guide 6 as the center. When the welding wire 3 swings, it will exert a force on the movable sleeve 4. After the movable sleeve 4 is subjected to force, the starting end will exert a force on the positioning ring 5. The positioning ring 5 rotates on the support platform 7 through the rotating seat 10, so that the movable sleeve 4 can swing synchronously with the welding wire 3 without interfering with the movement of the welding wire 3. Thus, it can move synchronously with the welding wire 3, so as to protect the welding wire 3.

[0025] When the welding wire 3 breaks unexpectedly, the two ends of the broken wire 3 will move in opposite directions and move away from each other. Without the limiting effect of the movable sleeve 4, the two ends of the welding wire 3 will swing in a wide range, which could easily injure the staff around the equipment. However, because the movable sleeve 4 is installed around the welding wire 3 and can move synchronously with it, the welding wire 3 is in the inner cavity of the movable sleeve 4. During the process of moving away from the broken wire, it will come into contact with the inner cavity of the movable sleeve 4 and most of the destructive force will be absorbed by the movable sleeve 4, thus preventing injury to the surrounding staff, greatly improving the safety of the workshop and reducing the occurrence of accidents.
