Description

Technical Field

[0001] This invention relates to the field of steel wire processing technology, specifically to an end face grinding device for steel wire processing. Background Technology

[0002] A steel wire end face grinding device is a device used to grind the end face of a steel wire to a smooth finish during the steel wire processing process. Existing steel wire end face grinding devices require personnel to hand-grind the end face of the steel wire and cannot grind the end faces of multiple steel wires simultaneously.

[0003] According to the end face grinding device for steel wire processing described in patent number CN216298828U, the device can grind the end faces of multiple steel wires simultaneously by setting a fixing mechanism, an alignment mechanism, and a clamping mechanism. The grinding mechanism allows the device to grind the end faces of multiple steel wires without the need for a person to hold the grinding device, which increases the work efficiency of the user. However, the grinding effect is poor, and it cannot quickly grind a large number of steel wires. Furthermore, it cannot grind the sides during grinding, which affects the grinding effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an end-face grinding device for steel wire processing, which solves the problems mentioned above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel wire end face grinding device, comprising a grinding box, a guide assembly for feeding steel wire is provided on the top of the grinding box, a grinding block driven by a drive mechanism is movably connected to the inner cavity of the grinding box, a grinding groove and a feeding groove are respectively opened in the inner cavity of the grinding block, a partition block is separated between the feeding groove and the grinding groove, the horizontal height of the partition block is higher than the lowest surface of the feeding groove, a top rod is fixedly connected to the top of the grinding block, a sleeve is slidably connected to the surface of the top rod, a guide block is fixedly connected to the inner cavity of the grinding box, the top end of the sleeve is rotatably connected to the inner cavity of the guide block, an arc plate is movably connected to the inner cavity of the guide block through a sliding groove, one side of the arc plate extends through and to the outside of the guide block, a ball bearing that abuts against the surface of the steel wire is rolledly connected to the surface of the arc plate, the arc plate and the sleeve are connected by a connecting rod, a limit groove is provided between the guide block and the grinding box, and the limit groove is connected to the sliding groove. The inner cavity of the moving groove is connected. In use, the steel wire is placed into the guide assembly, and after the steel wire is spread out, it falls into the limiting groove in the guide block. Then, the bottom end falls into the grinding groove of the grinding block. At this time, the drive mechanism drives the grinding block to reciprocate. The rough particles in the grinding groove grind the end of the steel wire. At the same time, the sleeve is driven to reciprocate within the guide block by the cooperation of the push rod and the sleeve. The sleeve drives the arc plate to reciprocate through the connecting rod. The ball bearings on the surface abut against the steel wire, causing the steel wire to rotate while reciprocating, so that all surfaces can be effectively ground. After grinding, the drive mechanism drives the grinding block to move downward first. At this time, the separator does not block the side of the steel wire. Then the grinding block rotates and moves the feeding groove below the steel wire. The steel wire loses the lower limit and slides out along the feeding groove to complete the processing and collection. Then the grinding block rotates and moves the grinding groove below the limiting groove to start grinding the end of the next batch of steel wire. A large number of steel wire ends can be processed at once.

[0006] As a further aspect of the present invention: the guiding assembly includes a feed hopper fixed to the top of the grinding box, the inner cavity of the feed hopper having an annular placement cavity, and a spreading wheel driven by a motor rotatably connected to the inner cavity of the feed hopper, the spreading wheel extending into the inner cavity of the annular placement cavity. In use, the steel wire is placed in the feed hopper, and then the motor drives the spreading wheel to rotate. The spreading wheel rotates and contacts the steel wire in the inner cavity of the annular placement cavity, spreading the steel wire flat in the annular placement cavity, facilitating the feeding of the steel wire and effectively preventing blockage.

[0007] As a further aspect of the present invention: the driving mechanism includes a lifting cylinder fixed in the inner cavity of the grinding box, and a rotating motor is fixedly connected to the top end of the piston rod of the lifting cylinder. The output shaft end of the rotating motor is fixedly connected to the bottom of the grinding block. In use, the rotating motor is driven to lift and lower by the lifting cylinder, thereby driving the grinding block to lift and lower. The grinding block is driven to rotate by the rotating motor to grind the end of the steel wire.

[0008] As a further aspect of the present invention: one end of the connecting rod penetrates and extends into the inner cavity of the arc-shaped plate. The inner cavity of the arc-shaped plate has an inner groove that slides and connects with the surface of the connecting rod. A limiting plate is fixedly connected to the surface of the connecting rod. A return spring that abuts against one end of the limiting plate is sleeved on the surface of the connecting rod. The other end of the return spring is fixedly connected to one side of the arc-shaped plate. In use, the ball bearings on the surface of the arc-shaped plate abut against the surface of the steel wire. Under the counter-thrust, the arc-shaped plate squeezes the return spring and moves toward the connecting rod, preventing the arc-shaped plate from exerting excessive pressure on the surface of the steel wire, which would cause the steel wire to be squeezed and deformed. When the feed chute moves below the steel wire, the sleeve drives the connecting rod to rotate, causing the arc-shaped plate to rotate into the guide block. At this time, the arc-shaped plate is squeezed and the return spring retracts into the sliding groove in the guide block.

[0009] As a further aspect of the present invention: both sides of the arc-shaped plate are provided with arc-shaped surfaces, and the inner cavity of the sliding groove is provided with a guide groove. The guide groove contacts the arc-shaped surface to squeeze the arc-shaped plate and drive the arc-shaped plate to retract the compression reset spring.

[0010] As a further aspect of the present invention: multiple connecting rods are provided and evenly distributed on one side of the arc-shaped plate, and the movement of the arc-shaped plate is guided by the connecting rods.

[0011] As a further aspect of the present invention: there is a guide groove communicating with the limiting groove between the guide block and the grinding box, and the guide groove facilitates the steel wire to fall into the limiting groove for processing.

[0012] As a further aspect of the present invention: two feeding grooves and two grinding grooves are provided, and they are symmetrically distributed within the grinding block. The feeding groove is provided through the grinding block from top to bottom.

[0013] In use, the steel wire is placed into the guide assembly and then into the feed hopper. The motor drives the spreading wheel to rotate, which contacts the steel wire inside the annular placement cavity, spreading the wire evenly within the cavity. This facilitates wire feeding and effectively prevents blockage. After spreading, the wire falls into the limiting groove within the guide block, and then its bottom end falls into the grinding groove of the grinding block. The drive mechanism then drives the grinding block to reciprocate, grinding the end of the wire with the coarse particles in the grinding groove. A lifting cylinder drives the rotating motor to raise and lower the grinding block, which in turn grinds the end of the wire. Simultaneously, the top rod and sleeve work together to drive the sleeve to reciprocate within the guide block. The sleeve, through a connecting rod, drives the arc plate to reciprocate, with ball bearings on its surface contacting the steel wire, causing the wire to rotate simultaneously during the reciprocating motion, ensuring even grinding of all surfaces. Both can be effectively polished. After polishing, the drive mechanism drives the polishing block to move downwards first. At this time, the separator does not block the side of the steel wire. Then the polishing block rotates and moves the feeding groove below the steel wire. The steel wire loses the lower limit and slides out along the feeding groove to complete the processing and collection. In use, the ball bearings on the surface of the arc plate abut against the surface of the steel wire. Under the reverse thrust, the arc plate squeezes the return spring and moves towards the connecting rod to prevent the arc plate from squeezing the surface of the steel wire too much, causing the steel wire to be squeezed and deformed. When the feeding groove moves below the steel wire, the sleeve drives the connecting rod to rotate, causing the arc plate to rotate into the guide block. At this time, the arc plate is squeezed and the return spring is retracted into the sliding groove in the guide block. Then the polishing block rotates and moves the polishing groove below the limit groove to start polishing the end of the next batch of steel wire. A large number of steel wire ends can be processed at once.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This invention involves placing steel wire into a guide assembly, where the wire is spread out and falls into a limiting groove within the guide block. Then, the bottom end falls into a grinding groove in a grinding block. The grinding block reciprocates, and the rough particles in the grinding groove grind the end of the steel wire. This effectively grinds the bottom and sides of a large quantity of steel wire. The steel wire rotates while reciprocating, ensuring that all surfaces are effectively ground. After grinding, the wire can be quickly discharged.

[0016] 2. In use, the steel wire is placed in the feed hopper, and then the motor drives the flattening wheel to rotate. The rotating flattening wheel contacts the steel wire in the annular placement cavity, flattening the steel wire inside the annular placement cavity, which facilitates the feeding of the steel wire and effectively prevents blockage.

[0023] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0024] Please see Figure 1-5This invention provides a technical solution: a steel wire end face grinding device, including a grinding box 1. A guide assembly for feeding steel wire is provided on the top of the grinding box 1. A grinding block 5, driven by a driving mechanism, is movably connected to the inner cavity of the grinding box 1. A grinding groove 10 and a feeding groove 22 are respectively opened in the inner cavity of the grinding block 5. A partition block 23 separates the feeding groove 22 and the grinding groove 10. The horizontal height of the partition block 23 is higher than the lowest surface of the feeding groove 22. A top rod 11 is fixedly connected to the top of the grinding block 5, and a sliding connection is made to the surface of the top rod 11. A guide block 4 is fixedly connected to the inner cavity of the sleeve 12 and the grinding box 1. The top end of the sleeve 12 is rotatably connected to the inner cavity of the guide block 4. An arc-shaped plate 15 is movably connected to the inner cavity of the guide block 4 through a sliding groove 25. One side of the arc-shaped plate 15 extends through and to the outer side of the guide block 4. A ball bearing 20 that abuts against the surface of the steel wire is rolled on the surface of the arc-shaped plate 15. The arc-shaped plate 15 and the sleeve 12 are connected by a connecting rod 14. A limiting groove 9 is separated between the guide block 4 and the grinding box 1. The limiting groove 9 communicates with the inner cavity of the sliding groove 25. In use, the steel wire is placed into the guide assembly, and after it spreads out, it falls into the limiting groove 9 in the guide block 4. Then, the bottom end falls into the grinding groove 10 of the grinding block 5. At this time, the drive mechanism drives the grinding block 5 to reciprocate. The rough particles in the grinding groove 10 grind the end of the steel wire. Meanwhile, the sleeve 12 is driven to reciprocate within the guide block 4 by the cooperation of the push rod 11 and the sleeve 12. At this time, the sleeve 12 drives the arc plate 15 to reciprocate through the connecting rod 14. The ball bearings 20 on the surface abut against the steel wire, causing the steel wire to move in... While reciprocating, it rotates, ensuring that all surfaces are effectively ground. After grinding, the drive mechanism drives the grinding block 5 to move downwards. At this time, the separator 23 does not obstruct the side of the steel wire. Then, the grinding block 5 rotates to move the feeding groove 22 below the steel wire. The steel wire loses its lower limit and slides out along the feeding groove 22 to complete the processing and collection. Then, the grinding block 5 rotates to move the grinding groove 10 below the limiting groove 9, and the end grinding of the next batch of steel wires is carried out again. A large number of steel wire ends can be processed at once.

[0025] The guiding assembly includes a feed hopper 2 fixed to the top of the grinding box 1. The inner cavity of the feed hopper 2 has an annular placement cavity 24. The inner cavity of the feed hopper 2 is rotatably connected to a spreading wheel 3 driven by a motor. The spreading wheel 3 extends into the inner cavity of the annular placement cavity 24. In use, the steel wire is placed in the feed hopper 2, and then the motor drives the spreading wheel 3 to rotate. The spreading wheel 3 rotates and contacts the steel wire in the inner cavity of the annular placement cavity 24, spreading the steel wire flat in the annular placement cavity 24, which facilitates the feeding of the steel wire and effectively prevents blockage.

[0026] The driving mechanism includes a lifting cylinder 6 fixed in the inner cavity of the grinding box 1. A rotary motor 7 is fixedly connected to the top of the piston rod of the lifting cylinder 6. The output shaft end of the rotary motor 7 is fixedly connected to the bottom of the grinding block 5. In use, the lifting cylinder 6 drives the rotary motor 7 to lift and lower, thereby driving the grinding block 5 to lift and lower. The rotary motor 7 drives the grinding block 5 to rotate to grind the end of the steel wire.

[0027] One end of the connecting rod 14 passes through and extends into the inner cavity of the arc plate 15. The inner cavity of the arc plate 15 has an inner groove 16 that slides and connects with the surface of the connecting rod 14. A limit plate 18 is fixedly connected to the surface of the connecting rod 14. A return spring 17 that abuts against one end of the limit plate 18 is sleeved on the surface of the connecting rod 14. The other end of the return spring 17 is fixedly connected to one side of the arc plate 15. In use, the ball bearings 20 on the surface of the arc plate 15 abut against the surface of the steel wire. Under the counter-thrust, the arc plate 15 squeezes the return spring 17 and moves toward the connecting rod 14 to prevent the arc plate 15 from exerting too much pressure on the surface of the steel wire, which would cause the steel wire to be squeezed and deformed. When the feed chute 22 moves below the steel wire, the sleeve 12 drives the connecting rod 14 to rotate, which in turn drives the arc plate 15 to rotate into the guide block 4. At this time, the arc plate 15 is squeezed and the return spring 17 retracts into the sliding groove 25 in the guide block 4.

[0028] Arc-shaped surfaces 19 are provided on both sides of the arc plate 15, and guide grooves 21 are provided in the inner cavity of the sliding groove 25. The guide grooves 21 contact the arc-shaped surfaces 19 and squeeze the arc plate 15, causing the arc plate 15 to squeeze the return spring 17 to retract.

[0029] Multiple connecting rods 14 are provided and evenly distributed on one side of the arc plate 15. The connecting rods 14 are used to guide the movement of the arc plate 15.

[0030] There is a guide groove 8 between the guide block 4 and the grinding box 1, which is connected to the limiting groove 9. The guide groove 8 facilitates the steel wire to fall into the limiting groove 9 for processing.

[0031] There are two feeding grooves 22 and two grinding grooves 10, which are symmetrically distributed in the grinding block 5. The feeding groove 22 runs through the grinding block 5 from top to bottom.

[0032] In use, the steel wire is placed into the guide assembly and then into the feed hopper 2. The motor drives the spreading wheel 3 to rotate, which contacts the steel wire inside the annular placement cavity 24, spreading the wire evenly within the cavity. This facilitates wire feeding and effectively prevents blockage. After spreading, the wire falls into the limiting groove 9 within the guide block 4, and then its bottom end falls into the grinding groove 10 of the grinding block 5. The drive mechanism then drives the grinding block 5 to reciprocate, passing through the grinding groove 10. The internal rough particles grind the end of the steel wire. The lifting cylinder 6 drives the rotating motor 7 to raise and lower, causing the grinding block 5 to move up and down. The rotating motor 7 drives the grinding block 5 to rotate and grind the end of the steel wire. Simultaneously, the top rod 11 and the sleeve 12 work together to cause the sleeve 12 to reciprocate within the guide block 4. The sleeve 12, through the connecting rod 14, drives the arc-shaped plate 15 to reciprocate. The ball bearings 20 on the surface abut against the steel wire, causing the steel wire to rotate while reciprocating, ensuring that all surfaces are ground. After effective grinding, the drive mechanism drives the grinding block 5 to move downwards. At this time, the separator 23 does not block the side of the steel wire. Then, the grinding block 5 rotates and moves the feeding groove 22 below the steel wire. The steel wire loses its lower limit and slides out along the feeding groove 22 to complete the processing and collection. In use, the ball bearings 20 on the surface of the arc plate 15 abut against the surface of the steel wire. Under the counter-thrust, the arc plate 15 squeezes the return spring 17 and moves towards the connecting rod 14 to prevent the arc plate 15 from squeezing the surface of the steel wire too much, causing the steel wire to be squeezed and deformed. When the feeding groove 22 moves below the steel wire, the sleeve 12 drives the connecting rod 14 to rotate, causing the arc plate 15 to rotate into the guide block 4. At this time, the arc plate 15 is squeezed and the return spring 17 retracts into the sliding groove 25 in the guide block 4. Then, the grinding block 5 rotates and moves the grinding groove 10 below the limit groove 9 to grind the end of the next batch of steel wire. A large number of steel wire ends can be processed at once.
