Description

Technical Field

[0001] The present invention relates to the technical field of guide equipment for wire bead winding machines, and in particular to a winding guide equipment for a wire bead winding machine with a circular cross-section. Background Art

[0002] At present, circular cross-section wire rings are usually wound using a winding machine. The working principle of the winding machine is to place the object to be wound in the center of the turntable, start the turntable motor to rotate, and naturally drive the turntable to rotate, so that the object is wound around the periphery.

[0003] When winding the wire ring, the existing winding machine will pass the ring core through the center of the turntable, and then pass one end of the circular cross-section steel wire through the guide roller and the winding device in turn, and then spot weld it to the surface of the ring core to fix it. Finally, the motor is started to drive the turntable in the winding device to rotate, which can drive the steel wire to be wound on the surface of the ring core. After passing through the guide roller, part of the movement trajectory of the steel wire is up and down reciprocating swing. Therefore, when the steel wire swings up or down, the steel wire will squeeze the guide roller, thereby causing the pressure at the contact point between the steel wire and the guide roller to increase. Excessive pressure may cause plastic deformation of the steel wire, thereby affecting the quality of the wire ring.

[0004] Based on this, we propose a winding guide device for a circular cross-section wire ring winding machine. Summary of the Invention

[0009] Preferably, the lubrication mechanism further comprises an airbag fixedly connected to the upper end of the U-shaped frame, the side wall of the airbag is fixedly connected to a one-way oil inlet pipe, the inner wall of the airbag is fixedly connected to a one-way oil outlet pipe, and the other end of the one-way oil outlet pipe is fixedly connected to a rotary joint.

[0010] Preferably, a tensioning mechanism is installed on the installation box, and the tensioning mechanism includes a slide groove opened on the side wall of the installation box, the inner wall of the slide groove is slidably connected to a slider, and the side wall of the slider is rotatably connected to a tensioning wheel through a pin shaft, and the driving wheel, driven wheel and tensioning wheel are connected by a synchronous belt.

[0011] Preferably, the tensioning mechanism further comprises a sliding rod fixedly connected to the inner wall of the slide groove, the side wall of the sliding rod is slidably connected to the slider, the side wall of the sliding rod is sleeved with a first spring, and the two ends of the first spring are respectively fixedly connected to the side wall of the slider and the inner wall of the slide groove.

[0012] Preferably, two pressure rods are symmetrically and slidably connected to the inner wall of the installation groove, and one end of the two pressure rods close to each other is fixedly connected to an arc-shaped damping plate.

[0013] Preferably, a resistance adjustment mechanism is installed on the U-shaped frame, and the resistance adjustment mechanism includes two first cavities symmetrically opened in the U-shaped frame, and a second cavity is opened in the U-shaped frame. One end of the two first cavities is connected to the second cavity, and the inner wall of the second cavity is symmetrically slidably connected to two fixed rods, one end of the two fixed rods extends into the first cavity and is fixedly connected to a slide cylinder, one end of the pressure rod extends into the slide cylinder, and a second spring is fixedly connected between the inner wall of the slide cylinder and the pressure rod.

[0014] Preferably, the resistance adjustment mechanism also includes a moving block slidably connected to the inner wall of the second cavity, the side wall of the moving block is symmetrically connected to two connecting rods, the other ends of the two connecting rods are respectively connected to one end of the two fixed rods, the inner wall of the second cavity is connected to a second screw, and the side wall of the second screw is threadedly connected to the moving block.

[0015] Preferably, one end of the second lead screw passes through the side wall of the U-shaped frame and is fixedly connected to a cross nut.

[0016] The present invention has the following beneficial effects: 1. By setting up a guiding mechanism, the guide roller can move with the swing of the steel wire during the steel wire winding process, which not only keeps the pressure at the contact point between the steel wire and the guide roller within a reasonable range, but also reduces the bending curvature of the steel wire, thereby preventing the steel wire from producing plastic deformation due to the swing of the steel wire; 2. By setting a torsion spring, the pressure will be reduced accordingly during the movement of the guide roller until the pressure is reduced to the point that the guide roller can no longer rotate. At this time, the guide roller will stop rotating. When the steel wire begins to swing downward, the pressure between the steel wire and the guide roller will be reduced to the minimum, and the friction will be reduced to the minimum. At this time, the torsion spring can overcome the friction and drive the rotating shaft to rotate in the opposite direction to reset, thereby driving the first lead screw to rotate in the opposite direction, driving the slide to move downward to reset, and driving the guide roller to move slowly downward, so that the guide roller always keeps in contact with the steel wire, limiting the position of the steel wire, and preventing the steel wire from swinging back and forth during its travel, causing the travel route to deviate and making the winding irregular. 3. By setting up a lubrication mechanism, the pressure between the steel wire and the guide roller increases. When the guide roller moves, the movement of the U-shaped frame will squeeze the airbag, and then the lubricating oil in the airbag will enter the hollow groove through the one-way oil outlet pipe, and then the lubricating oil will enter the oil inlet cavity through the connecting groove. Finally, the lubricating oil will flow out through multiple oil outlet holes, lubricating the steel wire, reducing the stress between the steel wire and the guide roller, and further reducing the risk of plastic deformation of the steel wire. 4. By setting up a damping adjustment mechanism and adjusting the resistance between the arc-shaped damping plate and the rotating shaft, the torque required for the rotation of the rotating shaft can be adjusted. Therefore, when guiding the softer steel wire, the torque required for the rotation of the rotating shaft is smaller. At this time, during the winding process, when the pressure between the steel wire and the guide roller increases by a very small amplitude, the guide roller can also make corresponding movements to reduce the stress, and the reaction is more sensitive, which can effectively ensure that the softer steel wire will not produce plastic deformation. For the harder steel wire, the torque required for the rotation of the rotating shaft is greater. At this time, during the winding process, when the pressure between the steel wire and the guide roller needs to increase by a large amplitude, the guide roller can make corresponding movements to reduce the stress, and the reaction is slower, which can ensure that the guide roller provides sufficient pressure to limit it.

[0019] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Reference Figure 1 - Figure 8 A winding guide device for a circular cross-section wire ring winding machine includes a mounting base 1 and further includes: The guiding mechanism includes two mounting boxes 2 fixedly connected to the side walls of the mounting seat 1, and the inner wall of each mounting box 2 is slidably connected to a slide 3, and the side wall of the slide 3 is fixedly connected to two adjusting rods 4. One end of the two adjusting rods 4 passes through the side wall of the mounting box 2 and is fixedly connected to a U-shaped frame 5. The inner wall of the U-shaped frame 5 is symmetrically provided with two mounting grooves 6. The inner walls of the two mounting grooves 6 are rotatably connected to a rotating shaft 7. The ends of the two rotating shafts 7 close to each other are fixedly connected to a guide roller 8. The inner wall of the mounting box 2 is rotatably connected to the first wire. Rod 9, the side wall of the first screw 9 is threadedly connected to the skateboard 3, the inner wall of the mounting box 2 is rotatably connected to the rotating rod 10, the side wall of the rotating rod 10 is fixedly connected to the first bevel gear 11, the side wall of the first screw 9 is fixedly connected to the second bevel gear 12, the first bevel gear 11 is meshed with the second bevel gear 12, one end of one of the rotating shafts 7 passes through the side wall of the U-shaped frame 5 and is fixedly connected to the driving wheel 13, one end of the rotating rod 10 passes through the side wall of the mounting box 2 and is fixedly connected to the driven wheel 14, and the driving wheel 13 is connected to the driven wheel 14 through a synchronous belt.

[0021] Furthermore, under normal circumstances, when the steel wire is traveling in a linear manner, the surface pressure of the two guide rollers 8 on the steel wire is moderate, which can maintain the necessary limiting pressure on the steel wire and will not cause excessive pressure on the steel wire to cause plastic deformation. Moreover, under the pressure at this time, the friction force generated between the steel wire and the guide rollers 8 when traveling in a linear manner will not cause the guide rollers 8 to rotate. In the winding process of the wire ring, the steel wire will swing upward or downward along the winding device. At this time, the steel wire will gradually increase the pressure on the guide rollers 8. As the pressure increases, the steel wire may produce plastic deformation, and when the pressure increases, the friction force between the steel wire and the guide rollers 8 will increase. When the friction force increases to cause the guide rollers 8 to rotate, the rotation of the guide rollers 8 will drive the rotating shaft 7 to rotate, thereby driving the driving wheel 13 to rotate, driving the driven wheel 14 to rotate, and then driving the rotating rod 10 to rotate, driving the first bevel gear 11 to rotate, thereby driving the second bevel gear 12 to rotate, and driving the first lead screw 9 to rotate, so that the slide plate 3 slides upward (such as Figure 5 As shown in the figure), the slide plate 3 will move upward through the adjusting rod 4, thereby driving the U-shaped frame 5 to move upward, and driving the guide roller 8 to move upward. At this time, due to the upward displacement of the guide roller 8, the pressure between the guide roller 8 and the steel wire will be reduced, and the bending curvature of the steel wire will also be reduced, thereby preventing the steel wire from being plastically deformed due to the swinging of the steel wire. On the contrary, when the steel wire swings downward, the guide roller 8 below will move downward synchronously.

[0022] A torsion spring 15 is fixedly sleeved on the side wall of one of the rotating shafts 7 , and one end of the torsion spring 15 is fixedly connected to the inner wall of the mounting groove 6 .

[0023] Furthermore, during the movement of the guide roller 8, the pressure will decrease accordingly until the pressure is reduced to the point that the guide roller 8 can no longer rotate. At this time, the guide roller 8 will stop rotating, and when the steel wire begins to swing downward, the pressure between the steel wire and the guide roller 8 will be reduced to the minimum, and the friction will be reduced to the minimum. At this time, the torsion spring 15 can overcome the friction and drive the rotating shaft 7 to rotate in the opposite direction and reset, and then drive the first screw 9 to rotate in the opposite direction, drive the slide plate 3 to move downward and reset, and drive the guide roller 8 to move slowly downward, so that the guide roller 8 always keeps in contact with the steel wire, limits the steel wire, and avoids the steel wire from swinging back and forth during its travel, causing the travel route to deviate and making the winding irregular.

[0024] A lubrication mechanism is installed on the guide roller 8, which includes an oil inlet chamber 16 opened in the guide roller 8. A plurality of oil outlet holes 17 are opened on the inner wall of the oil inlet chamber 16. A hollow groove 18 is opened in one of the rotating shafts 7. The hollow groove 18 is connected to the oil inlet chamber 16 through a connecting groove 19. The side wall of the U-shaped frame 5 is fixedly connected to the rotary joint 20 through a bracket. One end of the rotating shaft 7 passes through the side wall of the U-shaped frame 5 and is fixedly connected to the rotary joint 20.

[0025] The lubrication mechanism also includes an airbag 21 fixedly connected to the upper end of the U-shaped frame 5, and a one-way oil inlet pipe 22 is fixedly connected to the side wall of the airbag 21. The other end of the one-way oil inlet pipe 22 is connected to an external container for storing lubricating oil, and the one-way oil inlet pipe 22 only allows external lubricating oil to enter the airbag 21. A one-way oil outlet pipe 23 is fixedly connected to the inner wall of the airbag 21. The one-way oil outlet pipe 23 only allows the lubricating oil in the airbag 21 to be discharged, and the other end of the one-way oil outlet pipe 23 is fixedly connected to the rotary joint 20.

[0026] Furthermore, the pressure between the steel wire and the guide roller 8 increases, so that during the movement of the guide roller 8, the movement of the U-shaped frame 5 will squeeze the airbag 21, and then the lubricating oil in the airbag 21 will enter the hollow groove 18 through the one-way oil outlet pipe 23, and then the lubricating oil will enter the oil inlet chamber 16 through the connecting groove 19, and finally the lubricating oil will flow out through multiple oil outlet holes 17, lubricating the steel wire, reducing the stress between the steel wire and the guide roller 8, and further reducing the risk of plastic deformation of the steel wire. The lubricating oil will only be pumped out when the pressure between the steel wire and the guide roller 8 increases, and will not be pumped out under normal circumstances, which can effectively reduce the waste of lubricating oil. When the guide roller 8 is reset, the airbag 21 will be stretched. At this time, the external lubricating oil will be sucked into the airbag 21 through the one-way oil inlet pipe 22 for storage.

[0027] A tensioning mechanism is installed on the installation box 2, and the tensioning mechanism includes a slide groove 24 opened on the side wall of the installation box 2. A slider 25 is slidably connected to the inner wall of the slide groove 24, and the side wall of the slider 25 is rotatably connected to the tensioning wheel 26 through a pin shaft. The driving wheel 13, the driven wheel 14 and the tensioning wheel 26 are connected by a synchronous belt.

[0028] The tensioning mechanism also includes a slide rod 27 fixedly connected to the inner wall of the slide groove 24. The side wall of the slide rod 27 is slidably connected to the slider 25. The side wall of the slide rod 27 is sleeved with a first spring 28. The two ends of the first spring 28 are respectively fixedly connected to the side wall of the slider 25 and the inner wall of the slide groove 24.

[0029] It should be noted that when the U-shaped frame 5 moves, it will drive the driving wheel 13 to move. At this time, the slider 25 will move under the action of the first spring 28, thereby driving the tensioning wheel 26 to move horizontally, so that the synchronous belt always remains taut, thereby ensuring effective power transmission.

[0030] Two pressure rods 29 are symmetrically and slidably connected to the inner wall of the installation groove 6 , and one end of the two pressure rods 29 close to each other is fixedly connected to an arc-shaped damping plate 30 .

[0031] A resistance adjustment mechanism is installed on the U-shaped frame 5, which includes two first cavities 31 symmetrically opened in the U-shaped frame 5, a second cavity 32 opened in the U-shaped frame 5, one end of each of the two first cavities 31 is connected to the second cavity 32, and two fixed rods 33 are symmetrically slidably connected to the inner wall of the second cavity 32, one end of the two fixed rods 33 extends into the first cavity 31 and is fixedly connected to a slide cylinder 34, one end of the pressure rod 29 extends into the slide cylinder 34, and a second spring 35 is fixedly connected between the inner wall of the slide cylinder 34 and the pressure rod 29.

[0032] The resistance adjustment mechanism also includes a moving block 36 that is slidably connected to the inner wall of the second cavity 32. The side wall of the moving block 36 is symmetrically connected to two connecting rods 37. The other ends of the two connecting rods 37 are respectively connected to one end of the two fixed rods 33. The inner wall of the second cavity 32 is connected to a second lead screw 38, and the side wall of the second lead screw 38 is threadedly connected to the moving block 36.

[0033] One end of the second lead screw 38 passes through the side wall of the U-shaped frame 5 and is fixedly connected to a cross nut 39 .

[0034] Furthermore, when guiding steel wires of different hardness, the cross nut 39 can be rotated by an external plum blossom screwdriver, which can drive the second lead screw 38 to rotate, and then drive the moving block 36 to slide in the second cavity 32. The moving block 36 will drive the two fixed rods 33 to slide closer to each other or away from each other through the connecting rod 37, thereby changing the compression degree of the second spring 35. The greater the compression degree of the second spring 35, the greater the reaction force provided to the arc damping plate 30, and the greater the pressure applied by the arc damping plate 30 to the rotating shaft 7. Therefore, the damping of the rotating shaft 7 during rotation is greater, and the rotating shaft 7 requires a greater torque at this time. On the contrary, the smaller the compression degree of the second spring 35, the smaller the torque required for the rotation of the rotating shaft 7. Therefore, when guiding the softer steel wire, the cross nut 39 can be rotated by rotating the cross nut 39. The nut 39 reduces the compression degree of the second spring 35, and the torque required for the rotation of the shaft 7 is smaller. At this time, during the winding process, when the pressure between the steel wire and the guide roller 8 increases by a very small amplitude, the guide roller 8 can also make corresponding movements to reduce the stress, and the reaction is more sensitive, which can effectively ensure that the softer steel wire will not produce plastic deformation. On the contrary, for the harder steel wire, it will not easily produce plastic deformation, so the compression degree of the second spring 35 can be increased, and the torque required for the rotation of the shaft 7 is greater. At this time, during the winding process, when the pressure between the steel wire and the guide roller 8 needs to increase by a large amplitude, the guide roller 8 can make corresponding movements to reduce the stress, and the reaction is slower, which can ensure that the guide roller 8 provides sufficient pressure to limit it.

[0035] In the present invention, the mounting base 1 is fixed to the wire ring winding machine using bolts, and then one end of the wire is passed from the right side of the guide roller 8 to the left side (as shown in FIG. Figure 1 As shown), the steel wire is then passed through the winding device and finally spot welded to the coil core. During the winding process, the guide roller 8 can limit the movement of the steel wire to prevent the steel wire from swinging back and forth and causing irregular winding.

[0036] Under normal circumstances, when the steel wire is traveling in a linear manner, the surface pressure of the two guide rollers 8 on the steel wire is moderate, which can maintain the necessary limiting pressure on the steel wire and will not cause excessive pressure on the steel wire to cause plastic deformation. Moreover, under the pressure at this time, the friction force generated between the steel wire and the guide roller 8 when traveling in a linear manner will not cause the guide roller 8 to rotate. In the winding process of the wire ring, the steel wire will swing upward or downward along the winding device. At this time, the steel wire will gradually increase the pressure on the guide roller 8. As the pressure increases, the steel wire may produce plastic deformation, and when the pressure increases, the friction force between the steel wire and the guide roller 8 will increase. When the friction force increases to cause the guide roller 8 to rotate, the rotation of the guide roller 8 will drive the rotating shaft 7 to rotate, thereby driving the driving wheel 13 to rotate, driving the driven wheel 14 to rotate, and then driving the rotating rod 10 to rotate, driving the first bevel gear 11 to rotate, thereby driving the second bevel gear 12 to rotate, driving the first lead screw 9 to rotate, and causing the slide plate 3 to slide upward (such as Figure 5 As shown in the figure), the slide plate 3 will move upward through the adjusting rod 4, thereby driving the U-shaped frame 5 to move upward, and driving the guide roller 8 to move upward. At this time, due to the upward displacement of the guide roller 8, the pressure between the guide roller 8 and the steel wire will be reduced, and the bending curvature of the steel wire will also be reduced, thereby preventing the steel wire from being plastically deformed due to the swinging of the steel wire. On the contrary, when the steel wire swings downward, the guide roller 8 below will move downward synchronously.

[0037] During the movement of the guide roller 8, the pressure will decrease accordingly until the pressure is reduced to the point that the guide roller 8 can no longer rotate. At this time, the guide roller 8 will stop rotating, and when the steel wire begins to swing downward, the pressure between the steel wire and the guide roller 8 will be reduced to the minimum, and the friction will be reduced to the minimum. At this time, the torsion spring 15 can overcome the friction and drive the rotating shaft 7 to rotate in the opposite direction and reset, and then drive the first screw 9 to rotate in the opposite direction, drive the slide plate 3 to move downward and reset, and drive the guide roller 8 to move slowly downward, so that the guide roller 8 always keeps in contact with the steel wire, limits the steel wire, and avoids the steel wire from swinging back and forth during its travel, causing the travel route to deviate and making the winding irregular.

[0038] The pressure between the steel wire and the guide roller 8 increases, so that during the movement of the guide roller 8, the movement of the U-shaped frame 5 will squeeze the airbag 21, and then the lubricating oil in the airbag 21 will enter the hollow groove 18 through the one-way oil outlet pipe 23, and then the lubricating oil will enter the oil inlet chamber 16 through the connecting groove 19, and finally the lubricating oil will flow out through multiple oil outlet holes 17, which will lubricate the steel wire, reduce the stress between the steel wire and the guide roller 8, and further reduce the risk of plastic deformation of the steel wire. The lubricating oil will only be pumped out when the pressure between the steel wire and the guide roller 8 increases, and will not be pumped out under normal circumstances, which can effectively reduce the waste of lubricating oil. When the guide roller 8 is reset, the airbag 21 will be stretched. At this time, the external lubricating oil will be sucked into the airbag 21 through the one-way oil inlet pipe 22 for storage.

[0039] When guiding steel wires of different hardness, the cross nut 39 can be rotated by an external plum blossom screwdriver, which can drive the second lead screw 38 to rotate, and then drive the moving block 36 to slide in the second cavity 32. The moving block 36 will drive the two fixed rods 33 to slide closer to each other or away from each other through the connecting rod 37, thereby changing the compression degree of the second spring 35. The greater the compression degree of the second spring 35, the greater the reaction force provided to the arc damping plate 30, and the greater the pressure applied by the arc damping plate 30 to the rotating shaft 7. Therefore, the damping of the rotating shaft 7 when it rotates is greater, and the rotating shaft 7 requires a greater torque to rotate. On the contrary, the smaller the compression degree of the second spring 35, the smaller the torque required to rotate the rotating shaft 7. Therefore, when guiding the softer steel wire, the cross nut 3 9, so that the compression degree of the second spring 35 is reduced, and the torque required for the rotation of the shaft 7 is smaller. At this time, during the winding process, when the pressure between the steel wire and the guide roller 8 increases by a very small amplitude, the guide roller 8 can also make corresponding movements to reduce the stress, and the reaction is more sensitive, which can effectively ensure that the softer steel wire will not produce plastic deformation. On the contrary, for the harder steel wire, it will not easily produce plastic deformation, so the compression degree of the second spring 35 can be increased, and the torque required for the rotation of the shaft 7 is greater. At this time, during the winding process, when the pressure between the steel wire and the guide roller 8 needs to increase by a large amplitude, the guide roller 8 can make corresponding movements to reduce the stress, and the reaction is slower, which can ensure that the guide roller 8 provides sufficient pressure to limit it.
