Description

Technical Field

[0001] This invention relates to the field of tipping mill technology, specifically to a tipping mill for profiled steel wire used in end gradient forming. Background Technology

[0002] In fields such as machinery manufacturing, automotive parts, and precision instruments, shaped steel wires, with their unique cross-sectional shapes, can adapt to the assembly and transmission needs of different scenarios, becoming a core component of many products. The rolling process of shaped steel wires is a crucial step in its production. It requires gradient rolling of the steel wire using rollers to form a pre-set shaped cross-section. Simultaneously, it is essential to ensure the dimensional accuracy and shape regularity of the rolled steel wire, avoiding problems such as ellipticity, deformation, and surface defects, thus ensuring subsequent assembly and performance.

[0003] Existing rolling equipment lacks a spiral rotation adjustment structure for steel wires. During the rolling process, irregularly shaped steel wires only move in a straight line without circumferential rotation. The squeezing pressure of the rolls easily causes the steel wires to be rolled into an elliptical shape, resulting in distorted cross-sectional shape and becoming unqualified products.

[0032] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 12 The present invention provides a technical solution: Example 1, such as Figure 1 , Figure 2 and Figure 3 As shown, the overall support base of the equipment is the workbench 10. The workbench 10 is made of high-strength rigid material and is used to support various functional components to ensure the stability of the equipment during operation. All functional components are directly or indirectly installed on the workbench 10.

[0034] The worktable 10 is equipped with a reducer 11 and a motor 12, which together form a drive assembly to provide power for the rotation of the rolls and regulate the speed. The input end of the reducer 11 is fixedly connected to the output end of the motor 12 through a coupling to ensure that the power of the motor 12 can be stably transmitted to the reducer 11. The reducer 11 is used to regulate the output speed of the motor 12 to avoid the speed being too high or too low and affecting the rolling accuracy. The output end of the reducer 11 is fixedly connected to the second roll 3 through a coupling, which can drive the second roll 3 to rotate, and cooperate with the first roll 2 to complete the rolling of the special-shaped steel wire, realizing the gradient forming of the end of the special-shaped steel wire.

[0035] The roll holder 1 is fixedly installed on the workbench 10 by bolts. It has a frame structure and is used to assemble the first roll 2 and the second roll 3. The first roll 2 and the second roll 3 are rotatably installed on the inner side of the roll holder 1. They are arranged parallel to each other and correspond to each other. They cooperate with each other through synchronous rotation to roll the special steel wire into shape, realize the gradient forming processing of the end of the special steel wire. The gap between the two can be adjusted according to the processing requirements during the rolling process.

[0036] A first slide groove 4 is provided on the top of the workbench 10. The first slide groove 4 is arranged along the length of the workbench 10 and is used to provide a sliding carrier for the L-shaped rod 5. The L-shaped rod 5 is slidably fitted inside the first slide groove 4. A hydraulic cylinder 13 is fixedly installed inside the workbench 10 by bolts. The hydraulic cylinder 13 is arranged along the length of the first slide groove 4, and its output end is fixedly connected to the L-shaped rod 5 by bolts. It is used to drive the L-shaped rod 5 to move along the first slide groove 4, thereby driving the subsequent components to move synchronously and adjusting the relative position of the shaped steel wire and the roll.

[0037] A transverse rail 6 is fixedly installed on the top of the L-shaped rod 5 by welding. The transverse rail 6 is arranged in a horizontal direction. The transverse rail 6 is fitted with a sliding plate 7 inside to assist in adjusting the lateral position of the equipment components and to meet the rolling orientation adjustment requirements of the shaped steel wire. A T-shaped groove is opened on the outer side of the sliding plate 7, and a hydraulic rod 14 is fixed in the T-shaped groove by screws. By activating the hydraulic rod 14, the limiting plate 15 welded to its output end moves upward, thereby limiting and fixing the tail of the clamped shaped steel wire to prevent relative slippage of the shaped steel wire during continuous axial traction, which could lead to the loss of control of the entire device.

[0038] Example 2, as follows Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, a reinforcing rod 9 is fixedly installed on the inner side of the roll seat 1 by welding. The reinforcing rod 9 is arranged horizontally and parallel to the transverse rail 6 to provide installation support for the sliding sleeve frame 91. The outer side of the reinforcing rod 9 is slidably fitted with the sliding sleeve frame 91. The gap between the sliding sleeve frame 91 and the outer wall of the reinforcing rod 9 is precisely matched, allowing it to slide smoothly along the reinforcing rod 9. A threaded hole is opened at the top of the sliding sleeve frame 91, and a No. 1 bolt 92 is threaded into the threaded hole. The bottom end of the No. 1 bolt 92 fits snugly against the outer wall of the reinforcing rod 9. By tightening the No. 1 bolt 92, the sliding sleeve frame 91 can be locked and fixed on the reinforcing rod 9, thereby positioning the sliding sleeve frame 91 and preventing it from sliding randomly.

[0039] The outer side of the sliding sleeve 91 is fixedly connected to the fixed cylinder 81 by welding, which drives the fixed cylinder 81 to move synchronously. The fixed cylinder 81 has a cylindrical hollow structure and a spiral groove 82 is provided inside. The spiral groove 82 extends spirally along the inner wall of the fixed cylinder 81 to provide a sliding and rotation trajectory for the first slider 83. The first slider 83 slides and fits into the spiral groove 82, while driving the positioning cylinder 84 to make a spiral movement.

[0040] The positioning cylinder 84 is fixedly connected to the outside of the first slider 83 by welding. It has a cylindrical hollow structure and is coaxially sleeved inside the fixed cylinder 81. It is used to sleeve and position the special-shaped steel wire to ensure that the special-shaped steel wire does not shift during the rolling process. The outside of the positioning cylinder 84 is fixedly connected to the threaded sleeve 85 by welding. The threaded sleeve 85 is connected to the positioning cylinder 84. The second bolt 86 is threadedly connected to the inside of the threaded sleeve 85. The second bolt 86 can extend into the inside of the positioning cylinder 84. By tightening the second bolt 86, its extended end is tightly abutted against the outer wall of the special-shaped steel wire, thereby locking and fixing the positioning cylinder 84 and the special-shaped steel wire, thus completing the positioning of the special-shaped steel wire.

[0041] A support ring 87 is fixedly installed inside the fixed cylinder 81 by welding. The support ring 87 has a ring structure and is coaxially sleeved on the outside of the positioning cylinder 84. Its inner side is slidably adapted to the positioning cylinder 84, providing guidance and support for the movement of the positioning cylinder 84, and ensuring that the positioning cylinder 84 does not deviate or shake during the movement. A bearing 88 is fixedly connected to the outside of the positioning cylinder 84 by interference fit. The outer ring of the bearing 88 is welded and fixed to the inner wall of the outer receiving plate 89, realizing the rotational connection between the outer receiving plate 89 and the positioning cylinder 84, and ensuring that the outer receiving plate 89 remains stationary when the positioning cylinder 84 rotates.

[0042] The bottom of the outer plate 89 is fixedly connected to the slide plate 7 by welding and can move synchronously with the slide plate 7. A first spring 80 is fixedly connected to the outer side of the outer plate 89 by welding. The end of the first spring 80 away from the outer plate 89 is fixedly connected to the outer end face of the fixed cylinder 81 by welding. The first spring 80 is in a stretched state and is used to provide elastic restoring force for the positioning cylinder 84. After rolling is completed, it drives the positioning cylinder 84 and the special steel wire to return to their original positions.

[0043] Example 3, as follows Figure 6 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, an air cylinder 801 is sleeved on the outside of the fixed cylinder 81. The air cylinder 801 is fixedly connected to the fixed cylinder 81 through a bracket. The air cylinder 801 has a hollow structure inside and is used to store gas. A piston rod 802 is slidably fitted inside the air cylinder 801. The piston rod 802 and the inner wall of the air cylinder 801 are precisely matched, and the sealing performance is good. It can slide smoothly along the air cylinder 801. The pistonless end of the piston rod 802 is fixedly connected to the outer plate 89 by welding. It can move synchronously with the outer plate 89 to realize the inflation and deflation of the air cylinder 801.

[0044] A flow assembly 803 is fixedly installed on the top of the air cylinder 801 by welding, which is used to allow the air cylinder 801 to flow and replenish the gas inside. The flow nozzle 31 of the flow assembly 803 is fixedly installed on the top of the air cylinder 801 by welding and communicates with the inside of the air cylinder 801. A second slide groove 32 is opened inside the flow nozzle 31. The second slide groove 32 is arranged in the vertical direction of the flow nozzle 31 to provide a sliding track for the second slider 33. The second slider 33 slides and fits into the inside of the second slide groove 32, and the gap between it and the inner wall of the second slide groove 32 is precisely matched. It can slide smoothly up and down along the second slide groove 32. The second slider 33 is made of the same material as the piston 34, so that the gas from the outside and the gas inside the flow nozzle 31 cannot flow between each other through the second slide groove 32.

[0045] A piston 34 is fixedly connected to the bottom of the second slider 33 by welding. The piston 34 slides and fits into the inside of the flow nozzle 31, sealing with the inner wall of the flow nozzle 31 to control the air passage of the flow nozzle 31. A second spring 36 is fixedly connected to the center of the top of the piston 34 by welding. A bracket plate 35 is fixedly connected to the end of the second spring 36 away from the piston 34 by welding. The bracket plate 35 is fixedly connected to the top of the flow nozzle 31 by welding to fix and support the second spring 36 and the hollow cylinder 37. A conical filter 302 is installed in the flow nozzle 31 by screws. It is made of rigid material to prevent bending and collapse. Several filter holes are opened on its top.

[0046] A hollow cylinder 37 is fixedly installed at the center of the bottom of the frame plate 35 by welding. The hollow cylinder 37 has a cylindrical hollow structure and is sleeved on the outside of the second spring 36. An adapter hole is opened on the outside of the hollow cylinder 37, and a spring rod 38 is slidably fitted in the adapter hole. A spring is coaxially fitted on the outside of the spring rod 38. One end of the spring is fixedly connected to the spring rod 38 by welding, and the other end is fixedly connected to the outside of the hollow cylinder 37 by welding, which is used for the elastic reset of the spring rod 38. A groove is opened inside the hollow cylinder 37, and a bottom cone rod 39 is slidably fitted in the groove. The bottom cone rod 39 can slide up and down along the groove, and its bottom fits against the top of the piston 34. A vertical groove 30 is opened on the outside of the bottom cone rod 39. The vertical groove 30 is arranged in the vertical direction of the bottom cone rod 39. An abutment head 301 is fixedly connected to the inside of the vertical groove 30 by welding. The abutment head 301 is arranged corresponding to the spring rod 38 and is used to abut against the spring rod 38.

[0047] An air jet assembly 804 is fixedly installed by welding at the end of the air cylinder 801 away from the piston rod 802. This assembly is used to spray gas to clean up the debris generated during the rolling of the shaped steel wire. One end of the air jet pipe 21 of the air jet assembly 804 is fixedly connected to the air cylinder 801 by welding and communicates with the inside of the air cylinder 801. The other end faces the meshing point of the first roll 2 and the second roll 3 to ensure that the gas can be accurately blown to the rolling part. A filter screen 22 is fixedly connected by welding at the end of the air jet pipe 21 away from the air cylinder 801. This filter screen is used to filter the debris generated during the rolling and forming of the shaped steel wire and prevent the debris from clogging the air jet pipe 21 or splashing into the equipment.

[0048] A support seat 23 is fixedly installed at the jet end of the jet pipe 21 by welding. A fixed shaft 24 is fixedly installed inside the support seat 23 by welding. A sealing plate 25 is rotatably installed on the outside of the fixed shaft 24. The size of the sealing plate 25 is adapted to the opening of the jet end of the jet pipe 21. It is used to seal the jet pipe 21 when it is not in the jet state to prevent debris from entering the interior of the jet pipe 21. Both ends of the sealing plate 25 are fixedly connected to elastic strips 26 by welding. The end of the elastic strip 26 away from the sealing plate 25 is fixedly connected to the outside of the jet pipe 21 by welding to provide elastic restoring force for the sealing plate 25 and ensure that the sealing plate 25 tightly seals the jet pipe 21 when it is not in the jet state.

[0049] The working principle of this invention is as follows: First, the front end of the shaped steel wire is inserted into the right end of the positioning cylinder 84 and moved to the left along its interior until it extends one-third of the length of the main body. Then, through the threaded engagement of the No. 2 bolt 86 and the threaded sleeve 85, the No. 2 bolt 86 is tightly abutted against the outer wall of the shaped steel wire, thereby firmly locking the shaped steel wire to the positioning cylinder 84 and completing the positioning and fixing of the shaped steel wire. Immediately afterwards, the hydraulic rod 14 is activated, causing the limiting plate 15 connected to its output end to move upward along the T-shaped groove until it fits against the tail end of the shaped steel wire, thereby achieving axial limiting of the shaped steel wire.

[0050] The hydraulic cylinder 13 is activated, and its output end drives the L-shaped rod 5 to move forward along the first slide groove 4. The transverse rail 6 fixed to the top of the L-shaped rod 5 moves forward along with it. Since the sliding plate 7 inside the transverse rail 6 is fixedly connected to the outer plate 89, and the outer plate 89 is rotatably connected to the positioning cylinder 84 through the bearing 88, the positioning cylinder 84 will drive the front end of the shaped steel wire to move between the first roll 2 and the second roll 3, thereby realizing the gradient rolling of the end of the shaped steel wire.

[0051] The reinforcing rod 9 is arranged parallel to the transverse rail 6, and the reinforcing rod 9, the adjusting part 8, and the sliding plate 7 are fixedly connected. This structural design allows the sliding sleeve 91, which is slidably connected to the reinforcing rod 9, and the sliding plate 7, which is slidably connected inside the transverse rail 6, to move synchronously. This, in turn, drives the adjusting part 8 and the shaped steel wire to achieve lateral displacement, thereby achieving the purpose of adjusting the rolling orientation of the shaped steel wire and effectively avoiding the problem of not being able to adjust the shaped steel wire position due to local wear of the rolls.

[0052] As the positioning cylinder 84 moves forward, the first slider 83, fixed on its outer side, moves synchronously forward along the spiral groove 82 opened on the inner wall of the fixed cylinder 81, driving the positioning cylinder 84 and the shaped steel wire to move forward in a spiral motion, and realizing the shaped steel wire to rotate 360°, preventing it from being rolled into an elliptical shape during the rolling process. At the same time, the motor 12 is started, and the output end of the motor 12 is connected to the reducer 11 through a coupling. The reducer 11 drives the first roll 2 and the second roll 3 to rotate forward, rolling the moving shaped steel wire.

[0053] After rolling is completed, hydraulic cylinder 13 retracts, motor 12 and reducer 11 reverse, driving the two rolls to rotate in opposite directions; simultaneously, positioning cylinder 84 and shaped steel wire are reset under the elastic tension of spring 80. Specifically, when the upper and lower rolls of the tipping mill rotate inward by about 50°, the shaped steel wire is swallowed and thinned, and then the rolls immediately rotate outward to expel the thinned steel wire, completing a single rolling cycle.

[0054] When the positioning cylinder 84 moves forward, the outer plate 89, connected to it via the bearing 88, moves forward synchronously, thereby compressing the first spring 80. Simultaneously, the piston rod 802, fixed to the outer plate 89, extends into the air cylinder 801, compressing the gas stored within and causing it to be ejected from the front end of the jet pipe 21. The ejected gas can blow away debris generated during the rolling of the shaped steel wire, preventing debris from getting stuck between the rolls and the shaped steel wire and causing equipment jamming. Furthermore, the gas must be filtered through the filter screen 22 before being ejected from the jet pipe 21. The ejected airflow impacts the sealing plate 25, causing it to deflect outwards around the fixed shaft 24, ensuring smooth airflow. After the airflow is ejected, the sealing plate 25 resets under the elastic force of the elastic strip 26, resealing the front end of the jet pipe 21 to prevent some debris from passing through the filter screen 22 and entering the jet pipe 21, causing blockage.

[0055] When the piston rod 802 extends into the air cylinder 801, the compressed gas also enters the flow nozzle 31 and pushes the piston 34 upward, causing the piston 34 and its connected second slider 33 to move upward along the second slide groove 32. At the same time, the piston 34 seals the air port at the top of the flow nozzle 31. During the upward movement of the piston 34, it pushes the bottom cone rod 39 upward and retracts it into the hollow cylinder 37. When the bottom cone rod 39 moves, the contact head 301 fixed on its outer side moves upward synchronously and collides with the spring rod 38. The compressed spring rod 38 stretches the spring on its coaxial ring side and extends outward, ensuring that the bottom cone rod 39 is smoothly retracted into the hollow cylinder 37. During this collision, the piston 34 remains in the area with a larger inner diameter of the flow nozzle 31. The vibration generated by the collision can cause the dust and impurities adhering to the surface of the piston 34 to fall off, achieving self-cleaning of the piston 34. The dust adhering to the piston 34 will fall onto the cone filter screen 302. The surface of the cone filter screen 302 that comes into contact with the dust is smooth and made of anti-static material. Therefore, when the dust is on the cone filter screen 302, it will accumulate on the circumferential side of the upper surface of the cone filter screen 302 under the action of gravity and be collected. At the same time, when the compressed gas enters the interior of the flow nozzle 31 from the bottom, it will not interfere with the accumulated dust. It will only flow upward from the filter hole at the top. In addition, the flow component 803 is smaller in volume than other structures, so the gas will quickly fill the flow nozzle 31 without interfering with the dust accumulated inside.

[0056] When the piston rod 802 extends from the air cylinder 801, the sealing plate 25 seals the front end of the jet pipe 21, creating a negative pressure suction inside the flow nozzle 31. This causes the piston 34 to move from the area with a smaller inner diameter to the area with a larger inner diameter within the flow nozzle 31. At this time, outside air is drawn into the air cylinder 801 through the gap between the piston 34 and the area with a larger inner diameter in the flow nozzle 31, stretching the second spring 36. Simultaneously, the bottom cone rod 39 detaches from the hollow cylinder 37 under its own gravity, returning to its initial position, awaiting the next impact of the piston 34, thus completing a full air circulation and cleaning process.

[0057] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made by those skilled in the art based on the above concepts without creative effort shall fall within the scope of protection of the present invention.
