Description

Technical Field

[0001] The utility model relates to the technical field of spring bending machines for the processing of crochet needles in textile machinery, and particularly relates to a spring bending machine for the processing of mechanical crochet needles. Background Art

[0002] A spring bending machine is a device that can bend spring steel into any shape. When processing mechanical crochet needles for textile machines, a spring bending machine is often used for bending. The spring steel enters the interior of the spring bending machine through the feeding port for straightening. When it comes out from the discharging port, multiple hydraulic rods and bending members at the discharging port bend the spring steel into a crochet needle. After the bending is completed, the spring steel is cut by a cutting block, thus completing the bending of the crochet needle.

[0003] The inventor found during the daily use of the spring bending machine that the size of the discharging port of a general spring bending machine is fixed. Due to the different diameters of the spring steel, the spring steel will shake inside the discharging port. When the discharging port needs to rotate, the spring steel cannot rotate with the discharging port, resulting in inaccurate bending and thus causing an impact. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a spring bending machine is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A spring bending machine for the processing of crochet needles in textile machinery, including an operating table, a bending machine is fixedly connected to the upper top of the operating table, an outlet is rotatably connected to the side of the bending machine, a discharging port is movably arranged at the outlet, a clamping device is arranged on the surface of the discharging port, a replacing device is arranged on the surface of the outlet, an oil cylinder is fixedly connected to the side of the bending machine, a hydraulic rod is fixedly connected to the side of the oil cylinder, a cutting block is fixedly connected to the surface of the hydraulic rod, a bending plate is fixedly connected to one end of the hydraulic rod, a bending rod is fixedly connected to one end of the hydraulic rod, the clamping device includes a rectangular frame fixedly connected to the surface of the discharging port, a bidirectional screw rod is rotatably connected to the interior of the rectangular frame, a rectangular plate is threadedly connected to the surface of the bidirectional screw rod, a sliding rod is fixedly connected to the side of the rectangular plate, one end of the sliding rod is inserted into the interior of the discharging port, and a clamping plate is fixedly connected to one end of the sliding rod.

[0006] The effects achieved by the above components are as follows: Under the action of the clamping plate, the spring steel can be fixed inside the outlet and the discharging port, so that when the outlet rotates, the spring steel can rotate together, thus achieving the clamping effect.

[0007] Preferably, ropes are fixedly connected to both ends of the clamping plate, and the ropes are arranged at the position of the maximum distance between the clamping plates.

[0008] The effect achieved by the above components is that under the action of the pulling rope, the two ends of the clamping plate move relative to each other, thereby achieving the effect of clamping the spring steel.

[0009] Preferably, an arc groove is formed on the side surface of the clamping plate, and a pulling rope is clamped inside the arc groove.

[0010] The effect achieved by the above components is that under the action of the arc groove, the pulling rope can be clamped into the inside of the arc groove, thereby causing the two ends of the clamping plate to contract and clamp the spring steel.

[0011] Preferably, a circular groove is formed on the side surface of the clamping plate, and a ball is rotatably connected inside the circular groove.

[0012] The effect achieved by the above components is that under the action of the ball, the friction between the spring steel and the clamping plate becomes smaller, so that the spring steel can be conveniently extended. When bending the spring steel, if the diameter of the spring steel is smaller than the diameter of the discharge port, turn the bidirectional screw by hand to make the rectangular plate move relative to each other, so that the sliding rod moves into the inside of the discharge port, thereby causing the surface of the spring steel to squeeze the pulling rope, so that the two ends of the clamping plate contract relative to each other, and then the pulling rope is clamped into the inside of the arc groove. Under the action of the ball, the friction between the spring steel and the clamping plate becomes smaller, so that the spring steel can be conveniently extended, thereby achieving the effect of clamping the spring steel. Therefore, when the outlet rotates, the spring steel can rotate with the outlet, thereby achieving the clamping effect.

[0013] Preferably, the replacement device includes a circular groove formed on the side surface of the outlet, a snap ring is fixedly connected inside the circular groove, a groove is clamped inside the circular groove, a convex block is inserted into the circular groove, one end of the convex block is fixedly connected to one end of the discharge port, a ring is fixedly connected to the surface of the convex block, and an annular groove is formed on the surface of the convex block.

[0014] The effect achieved by the above components is that under the action of the snap ring, the annular groove and the ring, the convex block can be inserted into the inside of the circular groove, thereby achieving the disassembly effect and thus achieving the effect of replacing the discharge port.

[0015] Preferably, a rectangular block is fixedly connected to the inner wall of the convex block, and a rectangular groove is clamped on the inner wall of the circular groove.

[0016] The effect achieved by the above components is that under the action of the rectangular block and the rectangular groove, the discharge port will not be misaligned when splicing with the outlet.

[0017] Preferably, a clamping rod is fixedly connected to the surface of the outlet, and one end of the clamping rod is inserted into the inside of the convex block.

[0018] The effects achieved by the above components are as follows: Under the action of the clamping rod, the bump can be fixed inside the outlet, thereby achieving the fixing effect.

[0019] Preferably, a first spring is sleeved on the surface of the clamping rod, and both ends of the first spring are fixedly connected to the surface of the outlet and the end of the clamping rod away from the outlet respectively.

[0020] The effects achieved by the above components are as follows: Under the action of the first spring, the clamping rod is inserted into the inside of the bump in a self-locking manner, thereby achieving the fixing effect. When the outlet needs to be replaced, the outlet fixed on the surface of the outlet is removed, and the new outlet is inserted into the inside of the circular groove through the bump. Under the combined action of the clamping ring, the annular groove and the circular ring, the bump can be inserted into the inside of the circular groove, thereby achieving the disassembly effect, and thus achieving the effect of replacing the outlet. During installation, under the action of the rectangular block and the rectangular groove, the outlet will not be misaligned when spliced with the outlet. When the bump is completely inserted into the inside of the circular groove, under the action of the first spring, the clamping rod is inserted into the inside of the bump in a self-locking manner, thereby achieving the fixing effect, and thus achieving the replacement effect.

[0021] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0022] In the present utility model, by setting the clamping device, when bending the spring steel, if the diameter of the spring steel is smaller than the diameter of the outlet, turn the bidirectional screw by hand to make the rectangular plate move relatively, so that the sliding rod moves towards the inside of the outlet, thereby making the surface of the spring steel squeeze the pull rope, and then making the two ends of the clamping plate contract relatively, and then making the pull rope snap into the arc groove. Under the action of the ball, the friction between the spring steel and the clamping plate becomes smaller, so that the spring steel can be conveniently extended, thereby achieving the effect of clamping the spring steel. Furthermore, when the outlet rotates, the spring steel can rotate with the outlet, thereby achieving the clamping effect, and thus solving the problem that the spring steel cannot rotate with the outlet due to the mismatch between the diameter of the spring steel and the outlet.

[0028] Example 1, as Figures 1-4 shown, a spring bending machine for processing crochet hooks for textile machinery includes an operating table 1. A bending machine 4 is fixedly connected to the upper top of the operating table 1. An outlet 10 is rotatably connected to the side of the bending machine 4. A discharge port 9 is movably arranged on the surface of the outlet 10. A clamping device 2 is arranged on the surface of the discharge port 9. A replacement device 3 is arranged on the surface of the outlet 10. An oil cylinder 5 is fixedly connected to the side of the bending machine 4. A hydraulic rod is fixedly connected to the side of the oil cylinder 5. A cutting block 6 is fixedly connected to the surface of the hydraulic rod. One end of the hydraulic rod is fixedly connected to a bending plate 7. One end of the hydraulic rod is fixedly connected to a bending rod 8. When it is necessary to bend the crochet hook, the spring steel is pulled to the position of the outlet 10 through the traction component inside the bending machine 4 and extends out from the inside of the discharge port 9. The hydraulic rod is extended and retracted by the oil cylinder 5. Under the action of the rotating block, one end of the spring steel is bent into an arc shape. The spring steel is bent under the cooperation of the bending rod 8 and the bending plate 7. When the spring steel extends to a certain length, under the action of the oil cylinder 5, the hydraulic rod extends, so that the cutting block 6 moves relatively, and then the spring steel is cut off, thus completing the bending of the crochet hook.

[0029] Refer to Figure 2, the clamping device 2 includes a rectangular frame 21 fixedly connected to the surface of the discharge port 9. A bidirectional screw 22 is rotatably connected inside the rectangular frame 21. A rectangular plate 23 is threadedly connected to the surface of the bidirectional screw 22. A slide bar 24 is fixedly connected to the side of the rectangular plate 23. One end of the slide bar 24 is inserted into the discharge port 9. A clamping plate 25 is fixedly connected to one end of the slide bar 24. Under the action of the clamping plate 25, the spring steel can be fixed inside the outlet 10 and the discharge port 9. Thus, when the outlet 10 rotates, the spring steel can rotate along with it, achieving the clamping effect. Pulling ropes 27 are fixedly connected to both ends of the clamping plate 25. The pulling ropes 27 are arranged at the position of the maximum distance between the two ends of the clamping plate 25. Under the action of the pulling ropes 27, the two ends of the clamping plate 25 move relatively, achieving the effect of clamping the spring steel. An arc groove 28 is formed on the side of the clamping plate 25. The pulling rope 27 is clamped inside the arc groove 28. Under the action of the arc groove 28, the pulling rope 27 can be clamped into the arc groove 28, causing the two ends of the clamping plate 25 to contract and clamp the spring steel. A circular groove is formed on the side of the clamping plate 25. A ball 26 is rotatably connected inside the circular groove. Under the action of the ball 26, the friction between the spring steel and the clamping plate 25 is reduced, making it convenient for the spring steel to extend. When bending the spring steel, if the diameter of the spring steel is smaller than that of the discharge port 9, turn the bidirectional screw 22 by hand to make the rectangular plate 23 move relatively, causing the slide bar 24 to move into the discharge port 9. As a result, the surface of the spring steel presses the pulling rope 27, causing the two ends of the clamping plate 25 to contract relatively, and the pulling rope 27 is clamped into the arc groove 28. Under the action of the ball 26, the friction between the spring steel and the clamping plate 25 is reduced, making it convenient for the spring steel to extend, achieving the effect of clamping the spring steel. Thus, when the outlet 10 rotates, the spring steel can rotate along with the outlet 10, achieving the clamping effect.

[0030] Refer to Figures 3-4, the replacement device 3 includes a circular groove opened on the side of the outlet 10. A clamping ring 35 is fixedly connected inside the circular groove. A groove is clamped inside the circular groove. A convex block 31 is inserted into the circular groove. One end of the convex block 31 is fixedly connected to one end of the discharge port 9. A circular ring 32 is fixedly connected to the surface of the convex block 31. A ring groove 34 is clamped on the surface of the convex block 31. Under the action of the clamping ring 35, the ring groove 34 and the circular ring 32, the convex block 31 can be inserted into the circular groove, thus achieving the disassembly function, and further achieving the function of replacing the discharge port 9. A rectangular block 33 is fixedly connected to the inner wall of the convex block 31. A rectangular groove 38 is clamped on the inner wall of the circular groove. Under the action of the rectangular block 33 and the rectangular groove 38, the discharge port 9 will not be misaligned when splicing with the outlet 10. A clamping rod 36 is fixedly connected to the surface of the outlet 10. One end of the clamping rod 36 is inserted into the convex block 31. Under the action of the clamping rod 36, the convex block 31 can be fixed inside the outlet 10, thus achieving the fixing function. A first spring 37 is sleeved on the surface of the clamping rod 36. Both ends of the first spring 37 are fixedly connected to the surface of the outlet 10 and the end of the clamping rod 36 away from the outlet 10. Under the action of the first spring 37, the clamping rod 36 is inserted into the convex block 31 in a self-locking state, thus achieving the fixing function. When it is necessary to replace the discharge port 9, the discharge port 9 fixed on the surface of the outlet 10 is removed, and the new discharge port 9 is inserted into the circular groove through the convex block 31. Under the combined action of the clamping ring 35, the ring groove 34 and the circular ring 32, the convex block 31 can be inserted into the circular groove, thus achieving the disassembly function, and further achieving the function of replacing the discharge port 9. During installation, under the action of the rectangular block 33 and the rectangular groove 38, the discharge port 9 will not be misaligned when splicing with the outlet 10. When the convex block 31 is completely inserted into the circular groove, under the action of the first spring 37, the clamping rod 36 is inserted into the convex block 31 in a self-locking state, thus achieving the fixing function, and further achieving the replacement function.

[0031] Working principle: When a spring bending machine for processing crochet hooks of a textile machine is needed and the crochet hook needs to be bent, the spring steel is pulled to the position of the outlet 10 through the traction component inside the bending machine 4 and extends out from the inside of the discharge port 9. The hydraulic rod is telescoped through the oil cylinder 5. Under the action of the rotating block, one end of the spring steel is bent into an arc-shaped hook. The spring steel is bent under the cooperation of the bending rod 8 and the bending plate 7. When the spring steel extends to a certain length, under the action of the oil cylinder 5, the hydraulic rod extends, and then the cutting block 6 moves relatively, and then the spring steel is cut off, thus completing the bending of the crochet hook. When bending the spring steel, if the diameter of the spring steel is smaller than the diameter of the discharge port 9, turn the bidirectional screw 22 by hand to make the rectangular plate 23 move relatively, and then make the sliding rod 24 move into the discharge port 9, so that the surface of the spring steel squeezes the pull rope 27, and then the two ends of the clamping plate 25 contract relatively, and then the pull rope 27 is clamped into the arc groove 28. Under the action of the ball 26, the friction between the spring steel and the clamping plate 25 becomes smaller, and then the spring steel can be conveniently extended, thus achieving the effect of clamping the spring steel. Then, when the outlet 10 rotates, the spring steel can rotate with the outlet 10, thus achieving the clamping effect. When the discharge port 9 needs to be replaced, remove the discharge port 9 fixed on the surface of the outlet 10, and insert the new discharge port 9 into the circular groove through the convex block 31. Under the combined action of the snap ring 35, the annular groove 34 and the ring 32, the convex block 31 can be inserted into the circular groove, thus achieving the disassembly effect, and then achieving the effect of replacing the discharge port 9. During installation, under the action of the rectangular block 33 and the rectangular groove 38, the discharge port 9 will not be misaligned when splicing with the outlet 10. When the convex block 31 is completely inserted into the circular groove, under the action of the first spring 37, the clamping rod 36 is inserted into the convex block 31 in a self-locking state, thus achieving the fixing effect, and then achieving the replacement effect.
