Description

Technical Field

[0001] This utility model relates to the field of drawing technology, and in particular to a heat treatment drawing device for anti-fracture wire. Background Technology

[0002] When drawing steel wire, annealing is usually required before drawing. Since annealing takes time, the workpiece is in prolonged contact with the external environment during drawing, leading to decreased workpiece quality and lower efficiency. To address this, patent document CN109663826 B addresses this issue by designing a gas storage tank to create a circulating flow, allowing the ultra-thin tube to react with an inert gas to form a protective layer. This prevents oxidation of the ultra-thin tube with oxygen, ensuring workpiece quality. An electric push rod positions the ultra-thin tube between the first and second guide wheels, preventing deviation or knotting. Under the action of a sliding rod, slip ring, and strong spring, the push-pull rod keeps the extrusion rod in constant contact with the ultra-thin tube, preventing it from becoming tangled during winding and affecting the process. However, this patent lacks an additional structure between the wire drawing die and the wheels to prevent wire breakage. This poses a risk of wire breakage between the drawing die and the wheels during heat treatment drawing due to excessive instantaneous drawing force.

[0003] To solve the above problems, it is necessary to improve the structure of the drawing equipment based on the structure disclosed in CN109663826 B, so as to solve the above technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a heat treatment drawing device for anti-fracture wire.

[0005] The anti-fracture wire heat treatment drawing equipment provided by this utility model includes a fixed bracket, on which two symmetrically distributed mounting rods are fixedly installed, and guide rollers for guiding wire drawing are installed on the two mounting rods. Two rotating frames rotatably connected are installed on both sides of the guide rollers, and a rotatably connected sliding ring is installed on each of the rotating frames.

[0006] The two sliding rings on the same side of the guide roller are both sleeved on the same mounting rod and slidably connected to the mounting rod. The mounting rod is fitted with a spring and a tension sensor for monitoring the spring tension.

[0007] The mounting bracket is equipped with a lubricant box for applying lubricant to the wire.

[0008] Preferably, a central column is fixedly installed in the middle of the mounting rod, and springs are sleeved on the mounting rods on both sides of the central column.

[0009] Preferably, the tension sensor is fixedly installed on the intermediate column, and the sensing element of the tension sensor is fixedly embedded in the surface of the intermediate column.

[0010] Preferably, one end of the spring is fixedly connected to the sensing plate of the tension sensor embedded in the cylindrical surface of the intermediate column, and the other end of the spring is fixedly connected to the corresponding sliding ring.

[0011] Preferably, both ends of the material box are fixedly fitted with symmetrically distributed wire tubes, and the wire tubes and the guide rollers have grooves that correspond to each other.

[0012] Preferably, the material box is equipped with a threaded powder inlet pipe for adding powder to the material box.

[0013] Preferably, the fixing bracket is equipped with a material box for coating the wire with anti-rust liquid.

[0014] Compared with related technologies, the anti-fracture wire heat treatment drawing equipment provided by this utility model has the following beneficial effects:

[0015] Because the guide roller has a downward convex structure compared to the material boxes on both sides, a portion of the wire that is pulled around the guide roller forms a reserved wire section. Therefore, when the wire pulling wheel is started, the guide roller rises, allowing the reserved wire section to slide outward, thus providing cushioning for the taut cable. This avoids the risk of the wire breaking instantly due to sudden pulling or equipment vibration causing large swings, effectively reducing the risk of wire breakage during wire pulling.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 4 This utility model provides a heat treatment drawing device for anti-breakage wire, which includes a fixed bracket 5. The fixed bracket 5 is fixedly installed on the mounting plate of the patent with publication number CN109663826 B, so that the guide roller 1 is located between the wire wheels of the drawing die.

[0024] In the embodiments of this utility model, please refer to Figures 1 to 4 Two symmetrically distributed mounting rods 2 are fixedly installed on the fixed bracket 5, and guide rollers 1 for guiding wire pulling are installed on the two mounting rods 2. Two rotating frames 11 are rotatably connected to each other on both sides of the guide rollers 1. Each rotating frame 11 is equipped with a rotatably connected sliding ring 12. The two sliding rings 12 on the same side of the guide roller 1 are sleeved on the same mounting rod 2 and slidably connected to the mounting rod 2. A spring 3 is sleeved on the mounting rod 2, and a tension sensor 4 for monitoring the tension of the spring 3 is provided. Specifically:

[0025] A central column 21 is fixedly installed in the middle of the mounting rod 2, and springs 3 are sleeved on the mounting rods 2 on both sides of the central column 21. The tension sensor 4 is fixedly installed on the central column 21, and the sensing plate of the tension sensor 4 is fixedly embedded in the cylindrical surface of the central column 21. One end of the spring 3 is fixedly connected to the sensing plate of the tension sensor 4 embedded in the cylindrical surface of the central column 21, and the other end of the spring 3 is fixedly connected to the corresponding sliding ring 12.

[0026] It should be noted that the wire route is as follows: passing through the drawing die on the patent with publication number CN109663826 B → material box 6 on one side of the fixed bracket 5 → lower wheel surface of the guide roller 1 → material box 6 on the other side of the fixed bracket 5 → winding to the drawing wheel on the patent with publication number CN109663826 B;

[0027] When the wire is heat-treated and drawn, the wire passes over the lower surface of the guide roller 1, causing the guide roller 1 to be subjected to a pulling force from the upper side of the wire. At this time, the guide roller 1 drives the rotating frame 11 to slide outward along the mounting rod 2 away from the middle column 21 through the sliding ring 12. As a result, the guide roller 1 rises. At the same time, the spring 3 is stretched and the tensile stress is monitored by the tension sensor 4. Since the guide roller 1 has a convex structure compared with the material boxes 6 on both sides, a portion of the drawn wire that passes over the guide roller 1 constitutes a reserved wire portion. Therefore, when the wire drawing wheel in patent CN109663826 B is started, the guide roller 1 rises, so that the reserved wire portion can slide outward, allowing the cable at the taut point to be buffered. This avoids the risk of the wire breaking instantly due to sudden pulling or equipment vibration causing the wire to swing wildly. This effectively reduces the risk of wire breakage during drawing.

[0028] In the embodiments of this utility model, please refer to Figures 1 to 4 The fixed bracket 5 is equipped with a material box 6 for coating the wire with anti-rust liquid, and two sets of symmetrically distributed material boxes 6 are fixedly installed on the mounting rod 2. Both ends of the material box 6 are fixedly fitted with symmetrically distributed wire tubes 7, and the wire tubes 7 and the guide roller 1 have wire grooves corresponding to each other. The material box 6 is equipped with a threaded powder inlet pipe 8 for adding powder to the material box 6.

[0029] It should be noted that: by inverting the container containing the rust inhibitor and fixing its outlet to the threaded powder inlet pipe 8, the rust inhibitor can be provided to the material box 6, so that the rust inhibitor can be applied after the wire is pulled.

[0030] In this embodiment, a container containing other coating reagents can also be installed on the material box 6 to coat the drawn wire with other reagents.

[0031] The working principle of the anti-fracture wire heat treatment drawing equipment provided by this utility model is as follows:

[0032] When the wire is heat-treated and drawn, the wire passes over the lower surface of the guide roller 1, causing the guide roller 1 to be subjected to a pulling force from the upper side of the wire. At this time, the guide roller 1 drives the rotating frame 11 to slide outward along the mounting rod 2 away from the middle column 21 through the sliding ring 12. As a result, the guide roller 1 rises. At the same time, the spring 3 is stretched and the tensile stress is monitored by the tension sensor 4. Since the guide roller 1 has a convex structure compared with the material boxes 6 on both sides, a portion of the drawn wire that passes over the guide roller 1 constitutes a reserved wire portion. Therefore, when the wire drawing wheel in patent CN109663826 B is started, the guide roller 1 rises, so that the reserved wire portion can slide outward, allowing the cable at the taut point to be buffered. This avoids the risk of the wire breaking instantly due to sudden pulling or equipment vibration causing the wire to swing wildly. This effectively reduces the risk of wire breakage during drawing.

[0033] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
