Description

Technical Field

[0001] This utility model relates to the field of steel wire heat treatment technology, and in particular to an adjustable heat treatment device for steel wire. Background Technology

[0002] Adjustable heat treatment equipment for steel wire is a special heat treatment processing equipment for steel wire or similar metal materials. It has adjustable parameters such as temperature, time and tension to meet the heat treatment needs of different materials, specifications and performance requirements.

[0003] Currently, in the operation of steel wire heat treatment equipment, the coiled steel wire is first installed on an uncoiling frame. Then, the free end of the wire passes through multiple support frames and enters the heat treatment equipment for quenching and tempering, thereby improving the hardness, strength, and wear resistance of the steel wire. After being removed from the heat treatment equipment, the wire immediately enters a cooling device for rapid cooling. After being removed from the cooling device, the wire tension is adjusted by a tension control device to prevent deformation or breakage. Finally, the wire is coiled by a coiling device and is ready for market use. However, the distance between the uncoiling end of the wire and the heat treatment equipment is relatively large, necessitating the use of support frames to prevent the wire from moving into the heat treatment area. The wires in the equipment sag significantly due to their own weight (excessive sag can cause the wires to touch the ground, suffer friction damage, or become entangled). Existing support frames, which support and guide the wires, have through holes on their outer walls. During transmission, the free end of the wire passes through these holes first to prevent the amount of wire on the unwinding roller from decreasing and causing a change in the wire's position. However, the diameter of the through holes on existing transmission frames is not adjustable. If the diameter of the wire to be transmitted is larger than the diameter of the through hole, the support frame needs to be replaced. If the diameter of the through hole is too large, the wire is prone to sag during transmission, requiring workers to replace it with a support frame that matches the wire diameter. This increases the time and effort required for wire heat treatment and reduces the efficiency of the heat treatment process. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an adjustable heat treatment device for steel wire, which aims to improve the problems in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable heat treatment device for steel wire, comprising:

[0006] The adjustment frame has a support plate fixedly installed on one side, and the bottom of the support plate is fitted with fastening bolts through threaded engagement.

[0007] Adjustable components are located at both ends of the adjustment frame. These components can limit the movement of steel wires of different diameters, preventing the wires from sagging as they enter the heat treatment equipment.

[0008] As a further description of the above technical solution:

[0009] The adjusting component includes a drive disc and support blocks. Both ends of the adjusting frame are rotatably mounted with drive discs via rotating shafts. Multiple support blocks are fixedly installed in a ring-shaped distribution at one edge of each of the two drive discs. Each of the multiple support blocks has an insertion hole on one side for supporting the steel wire.

[0010] As a further description of the above technical solution:

[0026] 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.

[0027] Reference Figure 1-4 One embodiment of this utility model is an adjustable heat treatment device for steel wire, comprising:

[0028] The adjustment frame 1 has a support plate fixedly installed on one side. The bottom of the support plate is fitted with fastening bolts through threaded connection. The support plate at the bottom of the adjustment frame 1 can support the adjustment frame 1, and the fastening bolts at the bottom of the support plate can connect it to the ground, thereby improving the stability of the adjustment frame 1 (this is existing technology and will not be described in detail here).

[0029] Both ends of the adjusting frame 1 are rotatably mounted with drive discs 3 via rotating shafts. Multiple support blocks 4 are fixedly installed in a ring at one edge of each drive disc 3. Each support block 4 has a through hole for supporting the steel wire on one side. The multiple support blocks 4 are of different sizes, and the through holes on one side of the multiple support blocks 4 are of different diameters. When the steel wire needs to be transferred to the heat treatment equipment, a suitable support block 4 is selected according to the diameter of the steel wire so that the diameter of the through hole matches the diameter of the steel wire. Then, the drive disc 3 is rotated until the selected support block 4 is rotated directly above the adjusting frame 1 so that steel wires of different sizes can pass smoothly through the through hole.

[0030] Support cylinders 2 are symmetrically fixed on both sides of the top of the adjusting frame 1. Positioning pins 10 are slidably installed in the inner cavity of each of the two support cylinders 2. Positioning holes 12 that are compatible with the positioning pins 10 are arranged in a ring at the edge of the two drive discs 3 away from the support block 4. The number of positioning holes 12 is the same as the number of support blocks 4. The number of multiple positioning holes 12 opened at one end of the drive disc 3 is the same as the number of support blocks 4. At the same time, multiple positioning holes 12 correspond one-to-one with multiple support blocks 4. After the selected support block 4 is rotated to the top of the adjusting frame 1, it is pushed to slide along the axis of the positioning pin 10 until the end of the positioning pin 10 away from the support cylinder 2 is inserted into the inner cavity of the positioning hole 12 located directly above the adjusting frame 1. This can limit the rotation of the drive disc 3 and prevent the drive disc 3 from rotating when the steel wire passes through the inner cavity of the insertion hole, thus improving the smoothness and stability of the steel wire passing through the inner cavity of the insertion hole.

[0031] A top-compression spring 11 is fixedly installed on the inner wall of the support cylinder 2 away from its opening end. One end of the top-compression spring 11 is rotatably connected to one end of the positioning column 10. The outer walls of both positioning columns 10 are slidably fitted with guide tubes 8 connected to the top of the adjusting frame 1, and the outer walls of both positioning columns 10 are fixedly installed with limit blocks 9. One end of the guide tube 8 is provided with a receiving groove that matches the limit block 9. The top-compression spring 11 can provide a thrust to the positioning column 10 to move closer to the drive disk 3. When the drive disk 3 needs to be rotated, the positioning column 10 is pushed along the axial direction of the positioning column 10. Positioning post 10 is moved into the inner cavity of support cylinder 2, causing limiting block 9 to move out of the receiving groove until limiting block 9 moves between support cylinder 2 and guide tube 8. Then, it rotates along the axis of positioning post 10, causing limiting block 9 and receiving groove to be misaligned. Immediately afterwards, the thrust applied to the outer wall of positioning post 10 is removed. At this time, top pressure spring 11 converts elastic potential energy into kinetic energy for positioning post 10 to move until one side of limiting block 9 is tightly attached to one end of guide tube 8, and positioning post 10 can be moved out of the positioning hole 12.

[0032] When it is necessary to limit the drive disk 3, continuously rotate the positioning post 10 until the central axis of the limiting block 9 and the central axis of the receiving groove coincide. At this time, the force on one side of the limiting block 9 disappears, and the top pressure spring 11 can continue to release elastic potential energy, so that the positioning post 10 continues to move along the axial direction until one side of the limiting block 9 is in contact with the inner wall of the receiving groove. At this time, one end of the positioning post 10 is inserted into the inner cavity of the through hole, thus achieving the limitation of the drive disk 3.

[0033] Multiple insertion holes have annularly distributed sliding grooves inside their cavities. Limiting posts 5 are slidably installed within the cavities of these grooves. One end of each limiting post 5 is rotatably fitted with a limiting ball 7 for limiting the wire, while the other end is fixedly fitted with a return spring 6 connected to the inner wall of the sliding groove. When the wire is inserted into the cavity of the insertion hole, the outer wall of the wire adheres to the outer wall of the limiting ball 7, pressing against it and causing the limiting post 5 to move inward into the sliding groove. At this time, the return spring 6 is compressed, thus the multiple limiting balls 7 press and limit the outer wall of the wire, preventing friction between the outer wall and the inner wall of the insertion hole during movement and avoiding wear on the outer wall. As the wire moves, the limiting balls 7 rotate tangentially to the wire, reducing friction and improving the smoothness of the wire's movement.

[0034] The drive disk 3, support block 4, and positioning column 10 constitute an adjustment component. The adjustment component can limit the movement of steel wires of different diameters to prevent the steel wires from sagging when entering the heat treatment equipment. When heat treating steel wires of different sizes, the position of the support block 4 can be adjusted by rotating the drive disk 3, thereby adjusting the size of the insertion hole according to the size of the steel wire. This reduces the time and effort required for steel wire heat treatment and improves the efficiency of steel wire heat treatment.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
