Description

Technical Field

[0001] This utility model relates to the technical field of metal pressure processing, specifically to an adjustable installation structure for a wear-resistant liner plate of a wire spinning machine. Background Technology

[0002] In high-speed wire rod rolling production lines, the wire coiler, as a key terminal piece of equipment, undertakes the core task of winding high-temperature rolled wire (such as rebar and wire rod) into regular coils through high-speed rotation. Its operational stability directly determines the wire forming quality and production efficiency. To ensure production safety, the wire coiler is usually equipped with a protective cover. This cover prevents personnel from accidentally touching the high-speed rotating wire coiler head and also prevents foreign objects from falling in and causing equipment malfunctions. It is an indispensable safety protection component for the wire coiler. During the operation of the wire coiler, the high-speed moving wire is prone to friction and collision with the inner wall of the protective cover, leading to rapid wear of the inner wall. Therefore, wear-resistant liners are usually installed in the area of ​​the inner wall of the protective cover that comes into contact with the wire. The wear-resistant liners absorb friction and impact, protecting the protective cover itself from damage. At the same time, the smooth surface of the wear-resistant liners guides the wire to move smoothly, extending the service life of the protective cover and ensuring the quality of the wire.

[0003] Currently, the installation method of wear-resistant liners for existing spinning machines generally adopts a single fixed bolt connection structure: that is, bolt holes are pre-set on the back of the wear-resistant liner, and the wear-resistant liner is rigidly fixed by passing the bolt through the hole and tightening it with the threaded hole on the inner wall of the protective cover.

[0004] The shortcomings of the above-mentioned existing technical solutions are: wear-resistant liners are prone to localized uneven wear during use (such as faster wear in the area near the outlet of the spinneret). Since the position of the wear-resistant liner cannot be finely adjusted due to the installation of the fixing bolts, when the wear in a local area reaches its limit, even if other areas are still intact, the entire wear-resistant liner needs to be replaced, resulting in serious waste of materials and increasing the frequency of wear-resistant liner replacement and downtime maintenance time. Utility Model Content

[0005] This utility model provides an adjustable installation structure for wear-resistant liners of spinning machines, which can solve the problems in the prior art where wear-resistant liners are prone to localized uneven wear during use. Due to the fixed bolt installation, the position of the wear-resistant liners cannot be finely adjusted. When the wear in a local area reaches its limit, even if other areas are still intact, the entire wear-resistant liner needs to be replaced, resulting in serious waste of materials and increasing the frequency of wear-resistant liner replacement and downtime maintenance.

[0006] An adjustable mounting structure for a wear-resistant liner of a spinning machine includes a protective cover, a mounting base, a limiting plate, a wear-resistant liner, and an adjustment component. The protective cover has a circular structure, and its inner wall has a through groove arranged along the axis of the protective cover. One end of the mounting base is slidably disposed in the through groove. The limiting plate is horizontally fixedly connected to the other end of the mounting base. The end of the wear-resistant liner has a limiting slot that slidably engages with the limiting plate. The adjustment component is disposed on the protective cover and is used to adjust the position within the through groove of the mounting base.

[0007] According to one embodiment of the present invention, the adjusting assembly includes a threaded rod, which is rotatably disposed horizontally within a through groove, and the mounting base has a threaded hole that engages with the threaded rod. The adjusting assembly also includes an adjusting motor, which is fixedly connected to a protective cover, and the output end of the adjusting motor is coaxially fixedly connected to the threaded rod.

[0008] According to one embodiment of this utility model, the adjusting assembly includes a threaded rod, which is rotatably disposed horizontally within a through groove, and the mounting base has a threaded hole that mates with the threaded rod. The adjusting assembly also includes an adjusting handwheel and an anti-slip sleeve. The adjusting handwheel is rotatably connected to a protective cover, and is coaxially fixedly connected to the threaded rod. The anti-slip sleeve is fitted onto the side of the adjusting handwheel.

[0009] According to one embodiment of this utility model, the adjusting assembly includes a telescopic rod, which is fixedly connected to a protective cover, and the telescopic end of the telescopic rod is fixedly connected to a mounting base. The telescopic rod is an electric push rod.

[0010] According to one embodiment of this utility model, the side of the limiting insert plate is fixedly provided with symmetrically arranged limiting blocks, and the limiting slot has a limiting groove that slides with the limiting blocks. Both the limiting blocks and the limiting grooves are L-shaped.

[0011] According to one embodiment of the present invention, a recessed groove is formed at the opening of the limiting slot, a baffle is slidably arranged in the recessed groove, a screw hole is formed at the bottom of the recessed groove, and a through hole is formed in the baffle that communicates with the screw hole. A screw is inserted through the screw hole and the through hole.

[0012] The advantages of this utility model compared to the prior art are: By adjusting the component to drive the mounting base to slide along the through groove, the unworn area of ​​the wear-resistant liner can be moved to the friction concentration point, avoiding the problem of replacing the entire wear-resistant liner after local wear reaches its limit. Since local uneven wear can be compensated for through adjustment, the overall replacement cycle of the wear-resistant liner is greatly extended, reducing the number of times the spinning machine is shut down due to the replacement of the wear-resistant liner.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0018] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0019] like Figures 1 to 3 As shown, an adjustable mounting structure for a wear-resistant liner of a spinning machine includes a protective cover 1, a mounting base 2, a limiting plate 5, a wear-resistant liner 3, and an adjustment component 4. The protective cover 1 has a circular structure, and the inner wall of the protective cover 1 has a through groove 7 arranged along the axis of the protective cover 1. One end of the mounting base 2 is slidably disposed in the through groove 7. The limiting plate 5 is horizontally fixedly connected to the other end of the mounting base 2. The end of the wear-resistant liner 3 has a limiting slot 6 that is slidably connected to the limiting plate 5. The adjustment component 4 is disposed on the protective cover 1 and is used to adjust the position within the through groove 7 of the mounting base 2.

[0020] During the initial installation phase, one end of the mounting base 2 slides along the through groove 7 on the inner wall of the protective cover 1 to a preset position, and the mounting base 2 is fixed by the adjusting component 4; then the limiting slot 6 at the end of the wear-resistant liner 3 is aligned with the limiting insert 5 at the other end of the mounting base 2, and the wear-resistant liner 3 is pushed in the horizontal direction so that the limiting insert 5 is fully embedded in the limiting slot 6, completing the initial splicing of the wear-resistant liner 3 and the mounting base 2. At this time, the wear-resistant liner 3 forms a stable connection with the protective cover 1 through the mounting base 2, and its inner wall is adapted to the movement trajectory of the wire.

[0021] When the wear-resistant liner 3 experiences localized uneven wear, the mounting base 2 is driven to slide along the through groove 7 by the adjusting component 4. This pushes the mounting base 2 to move the wear-resistant liner 3 towards the unworn area, transferring the contact position between the wire and the wear-resistant liner 3 to the intact area. This ensures that the unworn part of the wear-resistant liner 3 accurately bears the friction of the wire, preventing the mounting base 2 from shifting due to vibration during high-speed operation. At this time, the wear-resistant liner 3 returns to a stable working state and can continue to withstand the friction and impact of the wire.

[0022] When the wear-resistant liner 3 is completely worn and needs to be replaced, simply pull out the old wear-resistant liner 3 along the direction of the limiting insert 5, replace it with a new wear-resistant liner 3, and then reposition it by engaging with the insert through the limiting slot 6. The replacement can be completed without disassembling or modifying the protective cover 1.

[0023] By adjusting the mounting base 2 along the through groove 7, the unworn area of ​​the wear-resistant liner 3 can be moved to the friction concentration point, avoiding the problem of replacing the entire wear-resistant liner 3 after local wear reaches its limit. Since local uneven wear can be compensated by adjustment, the overall replacement cycle of the wear-resistant liner 3 is greatly extended, reducing the number of times the spinning machine is shut down due to the replacement of the wear-resistant liner 3.

[0024] According to one embodiment of the present invention, the adjusting assembly 4 includes a threaded rod 8, which is rotatably disposed in a horizontal state within a through groove 7, and the mounting base 2 has a threaded hole 9 that mates with the threaded rod 8. The adjusting assembly 4 also includes an adjusting motor 10, which is fixedly connected to the protective cover 1, and the output end of the adjusting motor 10 is coaxially fixedly connected to the threaded rod 8.

[0025] When the wear-resistant liner 3 shows localized uneven wear, the adjusting motor 10 is started to rotate forward or backward according to the direction of uneven wear. The threaded rod 8 drives the mounting base 2 to move precisely, so that the unworn area of ​​the wear-resistant liner 3 is aligned with the friction point of the wire. After the adjustment is in place, the motor is de-energized. The thread locking force of the threaded rod 8 can prevent the mounting base 2 from shifting due to vibration.

[0026] According to one embodiment of this utility model, the adjusting assembly 4 includes a threaded rod 8, which is rotatably disposed horizontally within a through groove 7, and the mounting base 2 has a threaded hole 9 that mates with the threaded rod 8. The adjusting assembly 4 also includes an adjusting handwheel and an anti-slip sleeve. The adjusting handwheel is rotatably connected to the protective cover 1, and the adjusting handwheel is coaxially fixedly connected to the threaded rod 8. The anti-slip sleeve is fitted onto the side of the adjusting handwheel.

[0027] When the wear-resistant liner 3 is partially worn, rotate the adjusting handwheel to fine-tune the threaded rod 8, so that the mounting base 2 moves the wear-resistant liner 3 to the unworn area. During the adjustment process, the sliding resistance of the mounting base 2 can be felt by rotating the handwheel to avoid over-adjustment. The anti-slip sleeve can increase the friction of the hand and prevent slippage during operation in high-temperature environments.

[0028] According to one embodiment of this utility model, the adjusting component 4 includes a telescopic rod, which is fixedly connected to the protective cover 1, and the telescopic end of the telescopic rod is fixedly connected to the mounting base 2. The telescopic rod is an electric push rod. When the wear-resistant liner 3 is partially worn, the electric push rod is controlled to extend or retract according to the direction of wear. The telescopic end drives the mounting base 2 to move horizontally, so that the unworn area of ​​the wear-resistant liner 3 bears the friction of the wiring. After adjustment, the push rod is braked and locked to prevent the mounting base 2 from shifting.

[0029] According to one embodiment of this utility model, the side of the limiting insert plate 5 is fixedly provided with symmetrically arranged limiting blocks 11, and the limiting slot 6 has a limiting groove 12 that slides with the limiting blocks 11. Both the limiting blocks 11 and the limiting groove 12 are L-shaped. When splicing the wear-resistant liner 3, the limiting slot 6 is aligned with the limiting insert plate 5, and the wear-resistant liner 3 is pushed horizontally so that the L-shaped limiting blocks 11 are embedded in the L-shaped limiting groove 12. At this time, the transverse and longitudinal structures of the blocks can respectively limit the wear-resistant liner 3 from disengaging along the length direction of the insert plate and from shifting perpendicular to the direction of the insert plate.

[0030] According to one embodiment of this utility model, a recessed groove 13 is formed at the opening of the limiting slot 6, and a baffle 14 is slidably disposed in the recessed groove 13. A screw hole 16 is formed at the bottom of the recessed groove 13, and a through hole 15 communicating with the screw hole 16 is formed in the baffle 14. A screw 17 is inserted through the screw hole 16 and the through hole 15. When splicing the wear-resistant liner 3, the limiting insert 5 is first inserted into the limiting slot 6, and then the baffle 14 is slid along the recessed groove 13 to cover the opening of the slot, so that the through hole 15 of the baffle 14 is aligned with the screw hole 16 at the bottom of the recessed groove 13. The screw 17 is then screwed into the screw hole 16 through the through hole 15 to lock the position of the baffle 14. The baffle 14 can prevent the limiting insert 5 from coming out of the slot opening, forming a secondary fixation. When replacing the wear-resistant liner 3, unscrew the screw 17, and slide the baffle 14 to expose the slot. Then, pull out the old wear-resistant liner 3, replace it with the new wear-resistant liner 3, reinstall the baffle 14, and tighten the screw 17.

[0031] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
