Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel wire processing technology, and in particular to a steel wire cutting device. Background Technology
[0002] Steel wire is a type of metal wire with a circular or irregular cross-section, produced by processing hot-rolled wire rods through pickling, annealing, drawing, and other processes. The main processes in steel wire production include raw material selection, removal of iron oxide scale, drying, coating treatment, heat treatment, wire drawing, and plating treatment. It is a basic and important industrial raw material and product with high strength and high elasticity, and is widely used in construction, transportation, manufacturing, and all aspects of daily life.
[0003] However, in existing technologies, steel wires are typically cut as needed during processing. Most cutting devices currently have a guide frame. The steel wire is passed through the guide hole of the guide frame before being cut. However, the guide hole of the guide frame is usually designed to be a fixed size. This causes the steel wire to wobble inside the guide hole when cutting steel wires of different radii. As a result, the steel wire may bend during cutting. Slight bending requires manual straightening, which is troublesome. Excessive bending will affect the strength of the steel wire and cause it to break and become unusable. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a wire cutting device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wire cutting device, comprising: a base plate, a support frame fixedly installed on the top of the base plate, a hydraulic rod fixedly installed on the top of the support frame, a pressure plate fixedly installed through the bottom end of the hydraulic rod, a cutter fixedly installed at the bottom of the pressure plate, a guide structure provided on the top of the base plate, the guide structure including a guide frame, the guide frame fixedly installed on the top of the base plate, four guide arc plates provided on the inner side of the guide frame, a movable plate fixedly installed on one side of each of the four guide arc plates, a movable column fixedly installed on one side of each of the four movable plates, a turntable rotatably installed on one side of the guide frame, the turntable having four arc grooves, the four movable columns respectively disposed on the inner side of the four arc grooves and slidingly contacting the turntable, a limit block fixedly installed at one end of each of the four movable columns, and a buffer structure provided between the base plate and the support frame.
[0006] In a preferred embodiment, four fixing blocks are fixedly installed on one side of the guide frame, and rectangular grooves are opened in the middle of the four movable plates. The four fixing blocks are respectively disposed on the inner side of the four rectangular grooves and slide in contact with the four movable plates respectively.
[0007] In a preferred embodiment, an external gear ring is fixedly installed on the outer side of the turntable, a protective frame is fixedly installed on the top of the guide frame, and a gear is rotatably installed on one side of the protective frame, with the external gear ring and the gear meshing together.
[0008] In a preferred embodiment, a connecting shaft is fixedly installed on one side of the gear, one end of the connecting shaft passes through one side of the protective frame and is rotatably connected to the protective frame, a worm gear is fixedly installed on one end of the connecting shaft, a worm is rotatably installed on the inner side of the protective frame, the worm gear and the worm are meshed together, and a throttle is fixedly installed on one end of the worm through the top of the protective frame.
[0009] In a preferred embodiment, the buffer structure includes two upper connecting seats, both of which are fixedly installed on the bottom of the pressure plate, and an upper buffer pad is fixedly installed on the bottom of each of the two upper connecting seats.
[0010] In a preferred embodiment, two lower connecting seats are fixedly installed on the top of the base plate, and a lower buffer pad is fixedly installed on the top of each of the two lower connecting seats. The two upper connecting seats are respectively on the same vertical line as the two lower connecting seats.
[0011] In a preferred embodiment, two guide rods are fixedly installed between the base plate and the support frame. Both guide rods pass through the pressure plate and slide in contact with the pressure plate. Two buffer springs are fixedly installed between the base plate and the pressure plate.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. This utility model, through its guide structure, allows the four moving columns to slide within the four arc grooves according to their arc changes when the turntable rotates. This, in turn, drives the four moving plates and their guide arc plates on one side to move in a corresponding centered or outward direction. This allows for radius adjustment based on the different radii of the steel wires, effectively improving the applicability of the device. 2. Through the buffer structure, the two upper buffer pads and two lower buffer pads come into contact during cutting, which effectively buffers the impact force generated by the downward movement of the pressure plate. Then, the elastic deformation of the two buffer springs provides secondary buffering, which effectively absorbs and reduces the huge impact force generated during the cutting process, prevents the device from being damaged due to instantaneous rigid contact, and improves the performance of the device.

Detailed Implementation
[0020] 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. Example
[0021] like Figure 1-5As shown, this utility model provides a technical solution: a wire cutting device, comprising: a base plate 11, a support frame 12 fixedly installed on the top of the base plate 11, a hydraulic rod 13 fixedly installed on the top of the support frame 12, a pressure plate 14 fixedly installed through the bottom end of the hydraulic rod 13 through the support frame 12, a cutter 15 fixedly installed at the bottom of the pressure plate 14, a guide structure 2 provided on the top of the base plate 11, the guide structure 2 including a guide frame 21, the guide frame 21 fixedly installed on the top of the base plate 11, four guide arc plates 201 provided on the inner side of the guide frame 21, a movable plate 22 fixedly installed on one side of each of the four guide arc plates 201, a movable column 23 fixedly installed on one side of each of the four movable plates 22, a turntable 24 rotatably installed on one side of the guide frame 21, the turntable 24 having four arc grooves 25, the four movable columns 23 respectively disposed on the inner side of the four arc grooves 25 and slidingly contacting the turntable 24, and a limit block 26 fixedly installed at one end of each of the four movable columns 23. A buffer structure 3 is provided between the guide frame 21 and the support frame 12. Four fixing blocks 27 are fixedly installed on one side of the guide frame 21. A rectangular slide groove 28 is opened in the middle of each of the four moving plates 22. The four fixing blocks 27 are respectively set inside the four rectangular slide grooves 28 and slide in contact with the four moving plates 22. An external gear ring 29 is fixedly installed on the outer side of the turntable 24. A protective frame 210 is fixedly installed on the top of the guide frame 21. A gear 21 is rotatably installed on one side of the protective frame 210. 1. The external gear ring 29 and the gear 211 are meshed and connected. A connecting shaft 212 is fixedly installed on one side of the gear 211. One end of the connecting shaft 212 passes through one side of the protective frame 210 and is rotatably connected to the protective frame 210. A worm gear 213 is fixedly installed on one end of the connecting shaft 212. A worm 214 is rotatably installed on the inner side of the protective frame 210. The worm gear 213 and the worm 214 are meshed and connected. A throttle 215 is fixedly installed on one end of the worm 214 through the top of the protective frame 210.
[0022] In this embodiment, by cooperating with the four movable columns 23 and the four arc-shaped grooves 25 of the turntable 24, the positions of the four movable columns 23 can slide within the four arc-shaped grooves 25 according to the arc changes of the four arc-shaped grooves 25 when the turntable 24 rotates. This drives the four movable plates 22 and the guide arc plate 201 on one side to move accordingly to center or expand outward. Thus, the radius can be adjusted according to the steel wires of different radii, effectively improving the applicability of the device. By cooperating with the fixed block 27 and the rectangular slide groove 28, the fixed block 27 can effectively control the movable plates 22. 2. Limiting is implemented to ensure that when the turntable 24 rotates, it can stably drive the four moving plates 22 to move in the center or outward, avoiding the situation where the rotation angle of the moving plates 22 changes and affects the position of the four guide arc plates 201. This effectively ensures the reliability of the structure. Through the meshing of the worm gear 213 and worm 214, a self-locking effect can be achieved after the device is adjusted. This prevents the device from rotating during conveying, which would change the position of the four guide arc plates 201 and affect the conveying effect of the steel wire. This improves the stability of the structure. Example
[0023] like Figure 1 , 2 As shown in Figure 6, the buffer structure 3 includes two upper connecting seats 31, both of which are fixedly installed on the bottom of the pressure plate 14. An upper buffer pad 32 is fixedly installed on the bottom of each of the two upper connecting seats 31. Two lower connecting seats 33 are fixedly installed on the top of the base plate 11. A lower buffer pad 34 is fixedly installed on the top of each of the two lower connecting seats 33. The two upper connecting seats 31 and the two lower connecting seats 33 are on the same vertical line. Two guide rods 35 are fixedly installed between the base plate 11 and the support frame 12. Both guide rods 35 pass through the pressure plate 14 and slide in contact with the pressure plate 14. Two buffer springs 36 are fixedly installed between the base plate 11 and the pressure plate 14.
[0024] In this embodiment, by setting the two upper connecting seats 31 and the two lower connecting seats 33 to be located on the same vertical line, when the hydraulic rod 13 drives the pressure plate 14 to move downward, the two upper connecting seats 31 and the two upper buffer pads 32 at their bottom can stably land on the top positions of the two lower connecting seats 33 and the two lower buffer pads 34 at their top. Then, through the contact between the two upper buffer pads 32 and the two lower buffer pads 34, the impact force generated by the downward movement of the pressure plate 14 is effectively buffered initially. Then, through the elastic deformation of the two buffer springs 36, a secondary buffer is provided, thereby effectively absorbing and mitigating the huge impact force generated during the cutting process and preventing structural damage to the device due to instantaneous rigid contact. The two guide rods 35 can effectively guide the movement of the pressure plate 14, ensuring that the pressure plate 14 can always maintain a horizontal state during the up and down movement, thereby ensuring that the device can be accurately aligned during cutting and effectively preventing the device from deviating during cutting.
[0025] Working principle: like Figure 1-6 As shown, during use, the steel wire is conveyed through the four guide arc plates 201. When it moves to the required cutting length, the hydraulic rod 13 is activated. The hydraulic rod 13 drives the pressure plate 14 and the cutter 15 at its bottom to move downward, thereby cutting the steel wire. During the cutting process, the two upper connecting seats 31 and the two upper buffer pads 32 at their bottom can stably rest on the top positions of the two lower connecting seats 33 and the two lower buffer pads 34 at their top. Then, through the contact between the two upper buffer pads 32 and the two lower buffer pads 34, the impact force generated by the downward movement of the pressure plate 14 is initially buffered. Then, through the elastic deformation of the two buffer springs 36, a secondary buffer is provided, thereby effectively absorbing and mitigating the huge impact force generated during the cutting process, preventing structural damage to the device due to instantaneous rigid contact, and improving the device's performance. When it is necessary to cut steel wires of different radii, rotating the handle 215 drives the worm gear 214 to rotate, which in turn drives the worm wheel 213 to mesh and rotate. Then, through the connecting shaft 212, the gear 211 is driven to rotate, which in turn drives the external gear ring 29 to mesh and rotate, causing the turntable 24 to rotate. This causes the moving columns 23 inside the four arc-shaped grooves 25 to move accordingly, thereby causing the four moving plates 22 and the guide arc plate 201 on one side to move accordingly to center or expand in four directions. Thus, the device can be adjusted according to the radius of the steel wire, keeping the steel wire in a straight line during cutting and avoiding bending of the steel wire after cutting, which would affect subsequent use. This effectively improves the applicability of the device.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
