Description

Technical Field

[0001] This utility model relates to the field of stainless steel wire processing technology, specifically a roller drawing mechanism. Background Technology

[0002] During hot rolling of wire rod, the resulting wire rod exhibits significant out-of-roundness. This is typically addressed using cold drawing with dies, but this involves surface treatment of the metal, increasing processing costs, causing environmental pollution, and resulting in high sliding friction and energy consumption. Under the same pressure, smaller diameter rollers can generate greater rolling force; however, it's impossible to install a larger shaft on smaller diameter rollers to maintain this rolling force. This leads to insufficient pressure on the wire rod during processing, failing to meet processing requirements. Utility Model Content

[0003] The purpose of this invention is to provide a roller drawing mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a roller drawing mechanism, comprising a support frame and a work frame mounted on the support frame, wherein multiple sets of roller assemblies for processing wire bodies are mounted on the work frame; the roller assembly includes a mounting frame, a positioning frame is slidably connected inside the mounting frame, and a work roller is rotatably connected inside the positioning frame; a support roller is also rotatably connected inside the positioning frame via a bearing, and the support roller abuts against the work roller.

[0005] Furthermore, a motor for driving the work roller to rotate is mounted on the mounting frame.

[0006] Furthermore, a drive screw is rotatably connected to the positioning frame, and the drive screw is threadedly connected to the mounting frame.

[0007] Furthermore, the work frame has multiple sets of mounting slots for mounting the mounting frame.

[0008] Furthermore, a first extension frame is fixedly connected to the work frame, and a positioning hole is provided on the first extension frame. The wire body is slidably connected to the first extension frame through the positioning hole.

[0009] Furthermore, a second extension frame is fixedly connected to the work frame away from the first extension frame, and a positioning element is provided between the second extension frame and the wire body.

[0010] Furthermore, the positioning component includes two connecting rods that slide against each other on the second extension frame, and each connecting rod is fixedly connected with an adapter ring that is adapted to the wire body after rolling; an elastic element is provided between each connecting rod and the second extension frame, and the elastic force of the elastic element drives the adapter ring to abut against the wire body.

[0011] Furthermore, the elastic element includes a positioning spring, the second extension frame has a sliding groove, the connecting rod is slidably connected to the second extension frame through the sliding groove, and the positioning spring is installed between the sliding groove and the connecting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In this roller drawing mechanism, when the wire body passes through multiple working sections, the rotating work roller performs rolling operations on the wire body. During the rotation of the work roller, the support roller rotates, providing support force to the work roller and further improving the stability of the roller drawing mechanism during operation. Simultaneously, this roller drawing mechanism not only addresses the issue of roll installation space but also meets the rolling force requirements of the wire, and can pull out the processed wire with less force, improving processing efficiency and reducing costs and energy consumption. Preferably, the work roller is triangular with a convex surface, and the support roller is in close contact with the work roller (concave-convex fit), and the two rollers can roll on the frame, thereby further improving the stability of the roller drawing mechanism during operation. Furthermore, the axis of the support roller in this roller drawing mechanism is much larger than the axis of the work roller. Since the smaller diameter roller can generate a larger rolling force, it can further improve the rolling effect on the wire body. This application can also solve the problem of non-roundness of hot-rolled raw materials, so it can be used as a cold-drawing die to make finished products. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a roller drawing mechanism, including a support frame 1 and a working frame 2 installed on the support frame 1. The working frame 2 is equipped with multiple sets of roller assemblies for processing wire body 9. The roller assembly includes a mounting frame 3, a positioning frame 5 is slidably connected inside the mounting frame 3, and a working roller 4 is rotatably connected inside the positioning frame 5. A support roller 6 is also rotatably connected inside the positioning frame 5 through a bearing 7, and the support roller 6 abuts against the working roller 4.

[0023] Specifically, the roller forming mechanism includes a support frame 1 and a work frame 2 mounted on the support frame 1. Multiple sets of support legs are provided at the bottom of the support frame 1, and each support leg has an anti-slip pad on its bottom to improve the stability of the mechanism during operation. Multiple sets of roller assemblies for processing the wire body 9 are mounted on the work frame 2. Specifically, the roller assemblies are arranged in a circular array around the center of the wire body 9, and the angle between two adjacent roller assemblies is 120° to meet operational requirements. The roll assembly includes a mounting frame 3, inside which a positioning frame 5 is slidably connected, and a work roll 4 is rotatably connected inside the positioning frame 5. A support roll 6 is also rotatably connected inside the positioning frame 5 via a bearing 7. The support roll 6 abuts against the work roll 4. Therefore, during use, when the wire body 9 passes through multiple sets of work rolls 4, the work rolls 4 rotate to roll the wire body 9, and during the stroke of the work rolls 4, they drive the support roll 6 to rotate. At this moment, the rotation of the support roll 6 provides support force to the work rolls 4, further improving the stability of the roll pulling mechanism during operation. Simultaneously, this roll pulling mechanism not only meets the requirements of roll installation space but also satisfies the rolling force requirements of the wire, and can pull out the processed wire with less force, improving processing efficiency and reducing costs and energy consumption. Preferably, the work roll 4 is triangular with a convex surface, and the support roll 6 fits against the work roll 4 (convex-concave fit), and the two rolls can roll on the frame, thereby further improving the stability of the roll pulling mechanism during operation. Specifically, the axis of the support roller 6 in the roller drawing mechanism is much larger than the axis of the work roller 4. Since the smaller diameter roller can generate a larger rolling force, the rolling effect on the wire body can be further improved.

[0024] In the embodiments provided by this utility model, a motor 8 for driving the work roller 4 to rotate is installed on the mounting frame 3, providing power for the rotation of the work roller 4 and further meeting the work requirements.

[0025] In the embodiment provided by this utility model, a drive screw 16 is rotatably connected to the positioning frame 5, and the drive screw 16 is threadedly connected to the mounting frame 3. This allows for adjustment of the state between multiple sets of work rollers 4 according to work requirements, thereby improving the applicability of the roller pulling mechanism. Furthermore, a positioning element is provided between the positioning frame 5 and the mounting frame 3. The positioning element includes a positioning strip fixedly connected to the positioning frame, and a positioning groove adapted to the positioning strip is provided on the mounting frame 3. The positioning strip and the positioning groove are slidably connected to improve the stability of the positioning frame 5 when sliding. Specifically, the shaft on the work roller 4 is also mounted on the positioning frame 5 via the positioning element. When the positioning frame 5 slides, it drives the work roller 4 to slide.

[0026] In the embodiments provided by this utility model, the work frame 2 has multiple sets of mounting slots for mounting the mounting frame 3, thereby improving the stability of the mounting frame 3 during installation.

[0027] In the embodiment provided by this utility model, a first extension frame 10 is fixedly connected to the work frame 2. The first extension frame 10 has a positioning hole. The wire body 9 is slidably connected to the first extension frame 10 through the positioning hole, so that the wire body 9 can be initially positioned through the positioning hole to meet the work requirements.

[0028] In the embodiments provided by this utility model, a second extension frame 11 is fixedly connected to the work frame 2 away from the first extension frame 10. A positioning element is provided between the second extension frame 11 and the wire body 9. By setting the positioning element, the processed wire body 9 can be limited so that the wire body 9 before processing and the processed wire body 9 are on the same horizontal line, which meets the work requirements.

[0029] In the embodiments provided by this utility model, the positioning component includes two connecting rods 13 that are slidably connected to the second extension frame 11. Each connecting rod 13 is fixedly connected with an adapter ring 12 that is adapted to the wire body 9 after rolling. An elastic element is provided between each connecting rod 13 and the second extension frame 11. The elastic force of the elastic element drives the adapter ring 12 to abut against the wire body 9, resulting in better performance.

[0030] In the embodiments provided by this utility model, the elastic element includes a positioning spring 14, a sliding groove 15 is provided on the second extension frame 11, the connecting rod 13 is slidably connected to the second extension frame 11 through the sliding groove 15, and the positioning spring 14 is installed between the sliding groove 15 and the connecting rod 13 to improve the stability of the adapter ring 12 when sliding.
