Description

Technical Field

[0001] The present invention relates to the technical field of bead wire surface processing, in particular to a device for improving the surface roughness of a bead wire. Background Art

[0002] The bead wire is a steel wire embedded in the edge of the rubber tire. During the manufacturing process, the bead wire is clamped in the tire during the vulcanization process. The bead wire has to withstand extremely complex alternating loads and impact loads during tire use, which requires the bead wire to have good adhesion to the rubber. The bead wire must not only be firmly bonded to the rubber, but also cannot separate prematurely due to aging and hardening of the rubber during use.

[0003] At present, in order to roughen the surface of the bead wire, pickling, acid bath or sand bath are usually used. Although these methods can roughen the surface of the bead wire, they will also completely destroy the entire coating on the surface of the bead wire. Therefore, it will cause the bead wire to rust after long-term use, affecting the service life of the tire.

[0004] Based on this, we propose a device for improving the surface roughness of the tire bead wire. Summary of the Invention

A first spring is fixedly connected between the conductive sliding plug and the inner wall of the sliding cylinder.

[0012] Preferably, a resistance sleeve is embedded in the inner wall of one of the sliding cylinders. An annular electromagnet is fixedly connected to the inner wall of the sliding groove. A second spring is sleeved on the side wall of the limiting rod. The two ends of the second spring are respectively fixedly connected to the inner wall of the sliding groove and the side wall of the magnetic block.

[0013] Preferably, a cooling mechanism is installed on the fixing frame. The cooling mechanism includes a cooling block fixedly connected to the upper ends of the two fixing frames.

[0017] The present invention has the following beneficial effects:

[0018] 1. By setting up a grinding mechanism and a driving mechanism, the driving motor can drive the grinding roller to operate, grinding the surface of the bead wire to form arc grooves, thereby increasing the roughness of the bead wire surface. Compared with pickling, acid bath and other methods, it will not damage the coating on the surface of the bead wire;

[0019] 2. By setting up an annular electromagnet and a fixing mechanism, when the bead wire is squeezed by the fixing plate at the beginning, if the diameter of the bead wire is larger, the position of the conductive slider will be closer to the mounting frame. At this time, the resistance of the resistor sleeve connected to the circuit will be smaller, and the current flowing into the annular electromagnet will be larger, and the magnetism generated by the annular electromagnet will be stronger, which will generate a stronger suction force on the magnetic block, so that the position of the magnetic block is closer to the edge of the disc, which will increase the reciprocating swing amplitude of the push-pull frame, and the reciprocating stroke of the spline sleeve will increase, thereby increasing the stroke of the grinding roller. Therefore, the entire device can automatically adjust the stroke of the grinding roller according to the thickness of the bead wire to avoid inadequate grinding of the bead wire surface;

[0020] 3. By setting up a cooling mechanism, during the grinding process, when the magnetic block rotates eccentrically, it will synchronously drive the cross bar to slide back and forth through the second connecting rod, and then drive the slide plate to slide back and forth in a sealed manner. Under the action of the slide plate, the coolant will be pumped into the pump cylinder through the one-way liquid inlet pipe, and then the coolant in the pump cylinder will be squeezed into the liquid inlet cavity through the one-way liquid supply pipe. The coolant will then be sprayed out through multiple spray holes to cool the bead wire and grinding roller, ensuring that the bead wire will not be damaged;

[0021] 4. The thicker the bead wire, the more heat will be generated on its surface during grinding. Therefore, the change in the position of the magnetic block will increase the reciprocating stroke of the slide in the pump cylinder, and then more coolant will be pumped into the liquid inlet chamber. Therefore, the entire device can automatically adjust the amount of pumped coolant according to the thickness of the bead wire, thereby achieving better cooling effect and avoiding coolant waste.

[0022] 5. By setting the electric push rod and the arc plate, when it is necessary to adjust the surface roughness of the bead wire, the electric push rod can be driven to extend and retract to drive the arc plate to move, thereby equivalently changing the diameter of the driven wheel. Therefore, the rotation speed of the winding roller can be changed. If the winding roller rotates faster during the meshing of the sector gear and the second gear, the bead wire will move a longer distance. As a result, the arc grooves ground between the bead wires will be more sparsely distributed. On the contrary, they will be more densely distributed. Therefore, the surface roughness of the bead wire can be independently adjusted according to the actual situation, and the scope of application is wider. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0034] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementations disclosed below.

[0035] Refer to Figure 1 - Figure 10 , a device for improving the surface roughness of bead wire, comprising a base 1, and a mounting frame 2 fixedly connected to the upper end of the base 1;

[0036] A grinding mechanism, the grinding mechanism includes two first mounting plates 3 fixedly connected to the inner bottom of the mounting frame 2. A spline shaft 4 is rotatably connected to the side wall of one of the first mounting plates 3. A spline sleeve 5 is slidably connected to the side wall of the spline shaft 4. One end of the spline sleeve 5 penetrates through the side wall of the mounting frame 2 and is fixedly connected to a grinding roller 6. Two second mounting plates 7 are symmetrically and fixedly connected to the inner top of the mounting frame 2. A fixed shaft 8 is rotatably connected to the side walls of the two second mounting plates 7 facing each other. A push-pull frame 9 is rotatably connected to the side wall of the fixed shaft 8. Two connecting shafts 48 are symmetrically and slidably connected to the side wall of the spline sleeve 5. One end of the push-pull frame 9 is respectively rotatably connected to the side walls of the two connecting shafts 48;

[0037] A driving mechanism is installed on the first mounting plate 3. The driving mechanism includes a worm 16 rotatably connected to the side wall of the first mounting plate 3. One end of the worm 16 penetrates through the side wall of the first mounting plate 3 and is fixedly connected to a spline shaft 4. The inner wall of the mounting frame 2 is fixedly connected with a motor 18. The output end of the motor 18 is fixedly connected with a sector gear 19. One end of the worm 16 penetrates through the side wall of the first mounting plate 3 and is fixedly connected with a first gear 20.

[0038] It should be noted that an annular groove is formed in the side wall of the spline sleeve 5, and the connecting shaft 48 is slidably connected to the inner wall of the annular groove to ensure that the spline sleeve 5 can rotate synchronously.

[0039] The grinding mechanism further includes two third mounting plates 10 symmetrically and fixedly connected to the inner top of the mounting frame 2. A rotating shaft 11 is rotatably connected to the side walls of the two third mounting plates 10 close to each other. One end of the rotating shaft 11 penetrates through the side wall of the third mounting plate 10 and is fixedly connected with a disc 12. A chute 47 (as shown in Figure 6 shown) is formed in the side wall of the disc 12. A magnetic block 13 is slidably connected to the inner wall of the chute 47. A limiting rod 14 is fixedly connected to the inner wall of the chute 47. The side wall of the limiting rod 14 is slidably connected to the magnetic block 13. A first connecting rod 15 is rotatably connected to the side wall of the magnetic block 13. The other end of the first connecting rod 15 is rotatably connected to the side wall of the push-pull frame 9.

[0040] Further, when the driving motor 18 rotates, it drives the sector gear 19 to rotate. When the sector gear 19 rotates to mesh with the first gear 20, it drives the first gear 20 to rotate, and then drives the worm 16 to rotate, drives the spline shaft 4 to rotate, thereby driving the spline sleeve 5 to rotate, driving the grinding roller 6 to rotate. And when the worm 16 rotates, it synchronously drives the worm gear 17 to rotate, and then drives the rotating shaft 11 to rotate, thereby driving the disc 12 to rotate, driving the magnetic block 13 to rotate eccentrically. Then the magnetic block 13 drives the push-pull frame 9 to swing back and forth through the first connecting rod 15, and then drives the spline sleeve 5 to move first in the direction close to the fixing frame 21 and then reset. Thus, the grinding roller 6 rotates and advances at the same time, grinding the surface of the bead wire, so that an arc-shaped groove is ground on the surface of the bead wire, thereby improving the roughness of the surface of the bead wire. Compared with methods such as pickling and acid bath, it will not damage the coating on the surface of the bead wire.

[0041] A fixing mechanism is installed on the base 1. The fixing mechanism includes two fixing frames 21 symmetrically and fixedly connected to the upper end of the base 1. Two sliding cylinders 22 are symmetrically and fixedly connected to the side wall of the mounting frame 2. A conductive sliding plug 23 is slidably connected to the inner walls of the two sliding cylinders 22. A push rod 24 is fixedly connected to the side wall of the conductive sliding plug 23. One end of the push rod 24 penetrates through the side wall of the sliding cylinder 22 and the inner wall of the fixing frame 21 and is fixedly connected with a fixing plate 25. A first spring 26 is fixedly connected between the conductive sliding plug 23 and the inner wall of the sliding cylinder 22.

[0042] A resistor sleeve 27 is embedded in the inner wall of one of the slides 22, an annular electromagnet 28 is fixedly connected to the inner wall of the slide groove 47, a second spring 29 is sleeved on the side wall of the limit rod 14, and the two ends of the second spring 29 are respectively fixedly connected to the inner wall of the slide groove 47 and the side wall of the magnetic block 13. The resistor sleeve 27, the conductive slide plug 23, the annular electromagnet 28 and the external power supply are electrically connected through wires.

[0043] Furthermore, when the tire bead wire is squeezed by the fixed plate 25 at the beginning, if the diameter of the tire bead wire is larger, the position of the conductive slider 23 will be closer to the mounting frame 2. At this time, the resistance of the resistor sleeve 27 connected to the circuit will be smaller, and the current passed into the annular electromagnet 28 will be larger, and the magnetism generated by the annular electromagnet 28 will be greater, which will generate a stronger suction force on the magnetic block 13, so that the position of the magnetic block 13 is closer to the edge of the disc 12, and the amplitude of the reciprocating swing of the push-pull frame 9 will increase, and the reciprocating stroke of the spline sleeve 5 will increase, thereby increasing the stroke of the grinding roller 6. Therefore, the entire device can automatically adjust the stroke of the grinding roller 6 according to the thickness of the tire bead wire to avoid inadequate grinding of the tire bead wire surface.

[0044] A cooling mechanism is installed on the fixed frame 21, and the cooling mechanism includes a cooling block 30 fixedly connected to the upper ends of the two fixed frames 21, a liquid inlet cavity 31 is provided in the cooling block 30, and a plurality of liquid spray holes 32 are provided on the inner wall of the liquid inlet cavity 31, a pump cylinder 33 is fixedly connected to the inner wall of the mounting frame 2, a slide plate 34 is sealingly and slidingly connected to the inner wall of the pump cylinder 33, a one-way liquid inlet pipe 35 is fixedly connected to the side wall of the pump cylinder 33, the other end of the one-way liquid inlet pipe 35 is communicated with an external container for storing coolant, and the one-way liquid inlet pipe 35 only allows coolant to enter the pump cylinder 33, the pump cylinder 33 is communicated with the liquid inlet cavity 31 through a one-way liquid supply pipe 36, and the one-way liquid supply pipe 36 only allows the coolant in the pump cylinder 33 to enter the liquid inlet cavity 31.

[0045] The cooling mechanism also includes a cross bar 37 fixedly connected to the side wall of the slide 34. One end of the cross bar 37 passes through the side wall of the pump cylinder 33 and is rotatably connected to a second connecting rod 38. The other end of the second connecting rod 38 is rotatably connected to the side wall of the magnetic block 13.

[0046] It should be noted that a pin is fixedly connected to the side wall of the magnetic block 13 , and one end of the first connecting rod 15 and the second connecting rod 38 are both rotatably connected to the pin.

[0047] Furthermore, during the grinding process, when the magnetic block 13 rotates eccentrically, it will synchronously drive the cross bar 37 to reciprocate and slide through the second connecting rod 38, and then drive the sliding plate 34 to reciprocate and slide in a sealed manner. Under the action of the sliding plate 34, the coolant will be pumped into the liquid pumping cylinder 33 through the one-way liquid inlet pipe 35. Then, the coolant in the liquid pumping cylinder 33 will be squeezed into the liquid inlet cavity 31 through the one-way liquid supply pipe 36. Then, the coolant will be ejected through a plurality of liquid spraying holes 32 to cool the bead wire and the grinding roller 6, ensuring that the bead wire will not be damaged.

[0048] It is worth mentioning that for thicker bead wires, more heat will be generated on their surfaces during grinding. Therefore, when the position of the magnetic block 13 changes, the reciprocating stroke of the sliding plate 34 in the liquid pumping cylinder 33 will increase, and further, more coolant will be pumped into the liquid inlet cavity 31. Therefore, the entire device can automatically adjust the amount of coolant pumped according to the thickness of the bead wire, so as to achieve a better cooling effect and also avoid waste of coolant.

[0049] Four vertical plates 39 are fixedly connected to the upper end of the base 1. Among them, the side walls of the two vertical plates 39 on the same side that are close to each other are jointly rotatably connected with a winding roller 40. The side wall of the first mounting plate 3 is rotatably connected with a rotating rod 41, and a second gear 42 is fixedly connected to the side wall of the rotating rod 41.

[0050] A driving wheel 43 is fixedly connected to the side wall of the rotating rod 41. One end of one winding roller 40 penetrates through the side wall of the vertical plate 39 and is fixedly connected with a driven wheel 44. A plurality of electric push rods 45 are fixedly connected to the side wall of the driven wheel 44, and the active ends of the plurality of electric push rods 45 are all fixedly connected with arc-shaped plates 46. The driving wheel 43 and the arc-shaped plate 46 are connected by a synchronous belt.

[0051] It should be noted that the synchronous belt has a certain elasticity. Even when the arc-shaped plate 46 is in the position closest to the driven wheel 44, the tension of the synchronous belt is sufficient to provide enough friction force to drive the driven wheel 44 to rotate by the driving wheel 43.

[0052] Furthermore, when it is necessary to adjust the surface roughness of the bead wire, the electric push rod 45 can be driven to expand and contract to drive the arc-shaped plate 46 to move, which is equivalent to changing the diameter of the driven wheel 44. Therefore, the rotation speed of the winding roller 40 can be changed. If the winding roller 40 rotates faster during the meshing of the sector gear 19 and the second gear 42, the bead wire will move a longer distance. Furthermore, the arc-shaped grooves ground between the bead wires will be more sparsely distributed. On the contrary, they will be more densely distributed. Therefore, the surface roughness of the bead wire can be independently adjusted according to the actual situation, and the applicable range is wider.

[0053] In the present invention, one end of the bead wire is passed through between the fixing frames 21, and one end thereof is fixed to the surface of one of the winding rollers 40. The fixing plate 25 presses the bead wire under the action of the first spring 26, so that the section of the bead wire in contact with the grinding roller 6 remains linear, and no matter how the bead wire is conveyed, the section of the bead wire in contact with the grinding roller 6 always remains in the same position.

[0054] Then the driving motor 18 rotates to drive the sector gear 19 to rotate. When the sector gear 19 rotates to mesh with the first gear 20, it drives the first gear 20 to rotate, and then drives the worm 16 to rotate, drives the spline shaft 4 to rotate, thereby driving the spline sleeve 5 to rotate, drives the grinding roller 6 to rotate, and the rotation of the worm 16 synchronously drives the worm wheel 17 to rotate, and then drives the rotating shaft 11 to rotate, thereby driving the disc 12 to rotate, drives the magnet 13 to rotate eccentrically. Furthermore, the magnet 13 drives the push-pull frame 9 to swing back and forth through the first connecting rod 15, and then drives the spline sleeve 5 to move first in the direction close to the fixing frame 21 and then reset, so that the grinding roller 6 rotates and advances at the same time to grind the surface of the bead wire, so that an arc-shaped groove is ground on the surface of the bead wire. When the sector gear 19 rotates to mesh with the second gear 42, it drives the second gear 42 to rotate, thereby driving the rotating rod 41 to rotate, and then drives the driving wheel 43 to rotate, drives the driven wheel 44 to rotate, and then drives the winding roller 40 to rotate by a certain angle, so that the bead wire is translated by a certain distance, and then the surface of the bead wire can be ground again. Repeating this process, arc-shaped grooves will be ground on the surface of the bead wire, thereby increasing the roughness of the surface of the bead wire.

[0055] During the grinding process, when the magnet 13 rotates eccentrically, it synchronously drives the cross bar 37 to slide back and forth through the second connecting rod 38, and then drives the slide plate 34 to slide in a reciprocating and sealed manner. Under the action of the slide plate 34, the coolant is pumped into the liquid pump cylinder 33 through the one-way liquid inlet pipe 35, and then the coolant in the liquid pump cylinder 33 is squeezed into the liquid inlet cavity 31 through the one-way liquid supply pipe 36, and then the coolant is sprayed out through a plurality of liquid spraying holes 32 to cool the bead wire and the grinding roller 6, ensuring that the bead wire will not be damaged.

[0056] When the tire bead wire is squeezed by the fixed plate 25 at the beginning, if the diameter of the tire bead wire is larger, the position of the conductive slider 23 will be closer to the mounting frame 2. At this time, the resistance of the resistor sleeve 27 connected to the circuit will be smaller, and the current passed into the annular electromagnet 28 will be larger, and the magnetism generated by the annular electromagnet 28 will be greater, which will generate a stronger suction force on the magnetic block 13, so that the position of the magnetic block 13 is closer to the edge of the disc 12, and the amplitude of the reciprocating swing of the push-pull frame 9 will increase, and the reciprocating stroke of the spline sleeve 5 will increase, thereby increasing the stroke of the grinding roller 6. Therefore, the entire device can automatically adjust the stroke of the grinding roller 6 according to the thickness of the tire bead wire to avoid inadequate grinding of the tire bead wire surface.

[0057] As for the thicker the tire bead wire, more heat will be generated on its surface during grinding. Therefore, the change in the position of the magnetic block 13 will increase the reciprocating stroke of the slide 34 in the pump cylinder 33, and then more coolant will be pumped into the liquid inlet chamber 31. Therefore, the entire device can automatically adjust the amount of pumped coolant according to the thickness of the tire bead wire, so as to achieve better cooling effect and avoid waste of coolant.

[0058] When the roughness of the tire bead wire surface needs to be adjusted, the electric push rod 45 can be driven to extend and retract, driving the arc plate 46 to move, which is equivalent to changing the diameter of the driven wheel 44, so the rotation speed of the winding roller 40 can be changed. If the winding roller 40 rotates faster during the engagement between the sector gear 19 and the second gear 42, the tire bead wire will move a longer distance, and the arc grooves ground between the tire bead wires will be distributed more sparsely, on the contrary, they will be distributed more densely. Therefore, the roughness of the tire bead wire surface can be adjusted independently according to actual conditions, and the scope of application is wider.

[0059] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
