Description

Technical Field

[0001] The present invention relates to the technical field of brake pad production, and more particularly to a sheet forming device for producing the steel back of an automobile brake pad. Background Art

[0002] Brake pads, also known as brake leathers, are the most critical safety parts in a car's braking system. The working principle of the brake is mainly based on friction. The friction between the brake pads and the brake disc, and between the tires and the ground, is used to convert the vehicle's kinetic energy into heat energy after friction to stop the car. When installing the brake pads, a steel back must be fixed on them. The steel back is then installed in the car's braking system. The production quality of the steel back determines how the brake pads perform during vehicle driving.

[0003] When pressing the brake pad, the existing device places the steel sheet on the upper end of the workbench and passes through the upper pressing block (the shape of the brake pad). Since the brake pad needs to have a mounting hole when installing, the mounting hole will also be punched out during the stamping. When the punching head applies impact force to the steel sheet, certain burrs will appear on the inner wall of the mounting hole. At the same time, the steel sheet will be deformed by the downward force, and burrs will also appear at the lower end of the mounting hole. In this way, the staff will need to process the mounting hole position of the brake pad in the later stage before it can be used, which is a large workload and affects the processing efficiency of the brake pad.

[0004] Therefore, a sheet forming device for producing the steel back of an automobile brake pad is proposed. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) Through the provision of the first spring, when the moving block is reset, the one-way bearing acts to cause the rotating rod to drive the grinding disc and the grinding block to rotate, thereby grinding the burrs on the inner wall and the lower end of the mounting hole, making the mounting hole smoother. In this way, when the mounting hole is used later, the staff does not need to grind it again, which reduces manpower and improves the processing effect.

[0020] (2) The moving block drives the piston block to move, and the air pressure inside the rotating rod is increased through the first air pipe. The air pressure pushes the rectangular block to move. The rectangular block exerts a certain pressure on the inner wall of the mounting hole. The grinding block drives the rectangular block to rotate, which can better grind the mounting hole and improve the processing effect.

[0021] (3) The second air pipe is provided to enable the suction head to absorb dust, and the dust generated when the upper end of the moving block is polished is properly sucked out and falls into the inside of the chute, which can reduce the cleaning workload of the staff on the upper end of the moving block and improve the convenience of use.

[0022] (4) The pressing block always exerts a certain pressure on the steel sheet, and the hole-opening rod is retracted into the interior of the pressing block, so that the steel sheet is in a stable state. At the same time, the steel sheet is subjected to downward pressure, which increases the friction between the burr at the lower end of the mounting hole and the grinding disc, thereby improving the grinding effect of the burr.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 7 A sheet forming device for producing the steel back of an automobile brake pad comprises a processing table 1, the upper end of the processing table 1 is fixedly connected to a support rod 2, the upper end of the support rod 2 is fixedly connected to a top plate 3, the support rod 2 is used for supporting so that the top plate 3 is in a stable state, electric rods 4 are provided on both sides of the top plate 3, the electric rod 4 is a driving device, and its output end can perform telescopic movement, the output end of the electric rod 4 is provided with a pressure block 6, the electric rod 4 can drive the pressure block 6 to move up and down, a grinding assembly is provided inside the processing table 1, and the grinding assembly is used to grind the mounting holes of the brake pad;

[0034] The grinding mechanism includes a limiting groove 9 provided inside the processing table 1, and the steel sheet to be processed is placed in the limiting groove 9 at the upper end of the processing table 1. The shape of the limiting groove 9 is the shape of a brake. The internal sliding connection of the limiting groove 9 is provided with a moving block 10, and the moving block 10 can move up and down inside the limiting groove 9. The internal rotation of the moving block 10 is connected to a rotating rod 20, and the rotating rod 20 can rotate inside the moving block 10. The upper end of the rotating rod 20 is fixedly connected to a grinding disc 21, and the rotation of the rotating rod 20 drives the grinding disc 21 to rotate. A grinding block 22 is provided at the upper end of the grinding disc 21, and the grinding block 22 is slidably connected to the rotating rod 20. The grinding block 22 can move up and down relative to the rotating rod 20, and the lower end of the rotating rod 20 is fixed. A threaded rod 19 is fixedly connected, and both sides of the interior of the processing table 1 are fixedly connected with a one-way bearing 12. The one-way bearing 12 is a prior art. The inner ring and the outer ring can be locked in one direction and move in one direction. I will not go into details about this. The inner ring of the one-way bearing 12 and the rod wall of the threaded rod 19 are spirally transmitted. The lower end of the moving block 10 is fixedly connected with a rod 16. The movement of the moving block 10 drives the rod 16 to move. The lower end of the moving block 10 is fixedly connected with a first spring 17. The moving block 10 compresses the first spring 17 when it moves. When the upper end of the moving block 10 is not under pressure, the moving block 10 moves upward inside the limit groove 9, and the first spring 17 is sleeved on the outside of the rod 16;

[0035] During operation, the steel sheet to be processed is placed on the upper end of the processing table 1, at the position of the limit slot 9. At this time, the electric rod 4 drives the pressure block 6 to move downward, and under the action of the limit slot 9, the steel sheet is punched. It should be noted that when the brake pad is punched, it is necessary to punch out a mounting hole. The interior of the pressure block 6 is provided with a hole-opening mechanism. During the punching process, the moving block 10 is forced to move downward, compressing the first spring 17. The movement of the moving block 10 drives the threaded rod 19 to move downward. At this time, the inner ring and the outer ring of the one-way bearing 12 are in an active state, and the inner ring and the outer ring rotate relative to each other. The threaded rod 19 moves downward without rotating. When the stamping is completed, the electric rod 4 drives the pressure block 6 to move upward. At this time, the moving block 10 moves upward under the action of the first spring 17. At this time, the inner ring and the outer ring of the one-way bearing 12 are in a locked state, so when the threaded rod 19 moves upward, it will rotate. When the threaded rod 19 rotates, it drives the rotating rod 20 to rotate. The rotation of the rotating rod 20 drives the grinding disc 21 and the grinding block 22 to rotate. In this way, during processing, through the provided first spring 17, when the moving block 10 is reset, under the action of the one-way bearing 12, the rotating rod 20 drives the grinding disc 21 and the grinding block 22 to rotate, and then grinds the burrs on the inner wall and the lower end of the mounting hole, making the mounting hole smoother. In this way, when used later, the staff does not need to grind again, which reduces manpower and improves the processing effect.

[0036] like Figure 7As shown, first limit blocks 40 are provided at the front and rear positions of the inner wall of the limit groove 9. The first limit blocks 40 are used to limit the downward movement of the moving block 10 and can provide a stable support effect for the moving block 10 after the moving block 10 moves a certain distance.

[0037] like Figure 2-4 As shown, a cavity 11 is provided at the lower end of the processing table 1, and an air cylinder 13 is fixedly connected to the interior of the cavity 11, and a piston block 15 is sealed and slidably connected to the interior of the air cylinder 13. The piston block 15 can move up and down inside the air cylinder 13, and the upper end of the piston block 15 is fixedly connected to the lower end of the rod 16. The movement of the rod 16 drives the piston block 15 to move. Both sides of the upper end of the air cylinder 13 are fixedly connected to the first air pipe 18, and the first air pipe 18 is used for air guiding. Both sides of the lower end of the moving block 10 are rotatably connected to the air blocks 23, and the lower end of the rotating rod 20 is evenly provided with air holes 24. The air blocks 23 always wrap the air holes 24, so that when working, the rotating rod 20 rotates continuously, and the gas of the air block 23 can still enter the interior of the rotating rod 20. , both sides of the upper end of the inner part of the grinding block 22 are slidably connected with rectangular blocks 30, and the rectangular block 30 can move inside the grinding block 22, and the inner part of the grinding block 22 is slidably connected with a top block 34. The movement of the top block 34 makes the two grinding blocks 22 move to both sides, and the lower end of the rectangular block 30 is matched with the top block 34 for an inclined setting. The left side of the upper end of the air cylinder 13 is fixedly connected with a pressure valve 35, and the pressure valve 35 is a prior art to prevent the air pressure at the upper end of the air cylinder 13 from being too high. Rectangular openings 14 are provided on both sides of the lower end of the air cylinder 13. When the piston block 15 moves downward, the lower end of the air cylinder 13 is provided with a rectangular opening 14, which can keep the air pressure of the air cylinder 13 at the lower end of the piston block 15 unchanged, thereby preventing the air pressure at the lower end from affecting the movement of the piston block 15;

[0038] When the moving block 10 moves upward, it drives the rod 16 to move upward, and the rod 16 moves upward to drive the piston block 15 to move upward. The upward movement of the piston block 15 increases the air pressure of the air cylinder 13 at the upper end of the piston block 15, and the gas at the upper end of the air cylinder 13 is introduced into the interior of the air block 23 through the first air pipe 18, and the gas is passed into the interior of the rotating rod 20 through the air hole 24. At this time, the air pressure pushes the grinding block 22 to move upward. When the grinding block 22 moves up to a certain distance, the air pressure pushes the top block 34 to move upward. When the top block 34 moves up, the two rectangular blocks 30 slide outward and fit with the inner wall of the mounting hole. In this way, when the grinding block 22 rotates, the air pressure pushes the rectangular block 30 to move. The rectangular block 30 has a certain pressure on the inner wall of the mounting hole. The grinding block 22 drives the rectangular block 30 to rotate, which can better grind the mounting hole and improve the processing effect.

[0039] like Figure 5As shown, a second spring 31 is fixedly connected to the inside of the opposite side of the two rectangular blocks 30. The setting of the second spring 31 can reset the rectangular block 30. When the moving block 10 moves downward, the rectangular block 30 is no longer affected by the force of the top block 34 and then contracts. It should be noted that the second spring 31 makes the two rectangular blocks 30 have mutual pulling force. In this way, only when the grinding block 22 is completely moved up, the top block 34 has enough pressure to push the two rectangular blocks 30 apart, thereby ensuring the normal operation.

[0040] like Figure 5 As shown, the inside of the rotating rod 20 is fixedly connected to a round block 32, and the inside of the round block 32 is slidably connected to a slide rod 33. The upper end of the slide rod 33 is fixedly connected to the lower end of the grinding block 22. The grinding block 22 moves up and down, driving the slide rod 33 to move upward relative to the round block 32. When the rotating rod 20 rotates, it drives the round block 32 to rotate, the round block 32 drives the slide rod 33 to move, and the movement of the slide rod 33 drives the grinding block 22 to move. In this way, the grinding block 22 can rotate synchronously with the rotating rod 20, thereby ensuring the grinding work.

[0041] like Figure 7 As shown, inclined grooves 36 are provided at the front and rear positions of the processing table 1. The inclined surfaces of the inclined grooves 36 have a certain guiding function. The front and rear positions of the gas cylinder 13 are fixedly connected to second gas pipes 38. The second gas pipes 38 are used to guide gas. The upper end of the second gas pipe 38 is fixedly connected to an air suction head 37. An opening is provided at the position of the air suction head 37 inside the processing table 1. A one-way valve 39 is fixedly connected to the wall of the second gas pipe 38. The one-way valve 39 is a prior art and can pass gas in one direction. Cover plates 8 are provided at the front and rear positions of the processing table 1.

[0042] The moving block 10 drives the rod 16 to move downward, and the rod 16 drives the piston block 15 to move downward. At this time, the air pressure at the upper end of the air cylinder 13 is reduced, and the suction head 37 is dusted through the second air pipe 38. The dust generated when the upper end of the moving block 10 is polished is properly sucked away and falls into the inside of the chute 36. This can reduce the cleaning workload of the staff on the upper end of the moving block 10 and improve the convenience of use. In the later stage, he can clean the dust by opening the cover 8. The setting of the one-way valve 39 can prevent the suction head 37 from jetting and affecting the work.

[0043] like Figure 6As shown, the interior of the pressure block 6 is slidably connected with a cross plate 25, and the cross plate 25 can move up and down relative to the pressure block 6. The lower end of the cross plate 25 is fixedly connected to the hole rod 28. The movement of the cross plate 25 drives the hole rod 28 to move. The upper end of the cross plate 25 is fixedly connected to the output end of the electric rod 4. The movement of the electric rod 4 drives the cross plate 25 to move, and the output end of the electric rod 4 is slidably connected to the upper end of the pressure block 6. The lower ends of the cross plate 25 are fixedly connected with third springs 29 on both sides. The setting of the third spring 29 makes it possible for the cross plate 25 and the pressure block 6 to have an interaction force. The third spring 29 is sleeved on the outer side of the hole rod 28, and the inner wall of the pressure block 6 is fixedly connected with second limit blocks 27 on both sides to prevent the third spring 29 from being damaged when the pressure block 6 moves downward. The interior of the pressure block 6 is fixedly connected with a vertical rod 26. The vertical rod 26 provided makes the movement of the cross plate 25 more stable, and the rod wall of the vertical rod 26 is slidably connected to the interior of the cross plate 25.

[0044] The electric rod 4 drives the cross plate 25 to move downward. At this time, the pressure block 6 moves downward under the action of gravity. After the pressure block 6 contacts the steel sheet, the electric rod 4 continues to drive the cross plate 25 to move downward. The pressure block 6 drives the hole-opening rod 28 to move downward. The movement of the cross plate 25 has a downward thrust on the third spring 29. The third spring 29 has a downward thrust on the pressure block 6, and then punches the steel sheet. The hole-opening rod 28 continues to move downward to punch the position of the brake pad mounting hole. At this time, the grinding block 22 moves toward the inside of the rotating rod 20. When the work is completed, the electric rod 4 moves upward to drive the cross plate 25 to move upward. The movement of the cross plate 25 drives the hole-opening rod 28 relative to the pressure block 6 Move upward. It should be noted that at this time the elastic force of the third spring 29 is greater than the elastic force of the first spring 17, so that the cross plate 25 can move upward relative to the pressure block 6, so that the pressure block 6 has a certain pressure on the steel sheet when it moves upward, and the hole-opening rod 28 is retracted into the inside of the pressure block 6. At this time, the grinding block 22 moves up against the waste material and passes through the mounting hole. In this way, when working, since the pressure block 6 always has a certain pressure on the steel sheet, and the hole-opening rod 28 is retracted into the inside of the pressure block 6, the steel sheet is in a stable state. At the same time, the steel sheet is subjected to downward pressure, which increases the friction between the burr at the lower end of the mounting hole and the grinding disc 21, thereby improving the grinding effect of the burr.

[0045] like Figure 1 As shown, both sides of the pressing block 6 are fixedly connected with support blocks 7, and the interior of the support block 7 is slidably connected with a stabilizing rod 5. The lower end of the stabilizing rod 5 is fixedly connected to the upper end of the processing table 1 and the lower end of the top plate 3, so that the movement of the pressing block 6 is more stable.

[0046] Working principle: When working, the steel sheet to be processed is placed on the upper end of the processing table 1, at the position of the limit slot 9. At this time, the electric rod 4 drives the pressure block 6 to move downward, and under the action of the limit slot 9, the steel sheet is stamped. It should be noted that when the brake pad is stamped, it is necessary to punch out a mounting hole. The inside of the pressure block 6 is provided with a hole-opening mechanism. During the stamping process, the moving block 10 is forced to move downward, compressing the first spring 17. The movement of the moving block 10 drives the threaded rod 19 to move downward. At this time, the inner ring and the outer ring of the one-way bearing 12 are in an active state, and the inner ring and the outer ring rotate relative to each other. The threaded rod 19 moves downward without rotating. When the stamping is completed, the electric rod 4 drives the pressure block 6 to move upward. At this time, the moving block 10 moves upward under the action of the first spring 17. At this time, the inner ring and the outer ring of the one-way bearing 12 are in a locked state. Therefore, when the threaded rod 19 moves upward, it will rotate. When the threaded rod 19 rotates, it drives the rotating rod 20 to rotate. The rotation of the rotating rod 20 drives the grinding disc 21 and the grinding block 22 to rotate. In this way, during processing, through the provided first spring 17, when the moving block 10 is reset, under the action of the one-way bearing 12, the rotating rod 20 drives the grinding disc 21 and the grinding block 22 to rotate, thereby grinding the burrs on the inner wall and the lower end of the mounting hole, making the mounting hole smoother. In this way, when used later, the staff does not need to grind again, which reduces manpower and improves the processing effect.

[0047] Furthermore, when the moving block 10 moves upward, the rod 16 moves upward, and the rod 16 moves upward to drive the piston block 15 to move upward. The upward movement of the piston block 15 increases the air pressure of the air cylinder 13 at the upper end of the piston block 15, and the air at the upper end of the air cylinder 13 is introduced into the interior of the air block 23 through the first air pipe 18, and the air is passed into the interior of the rotating rod 20 through the air hole 24. At this time, the air pressure pushes the grinding block 22 to move upward. When the grinding block 22 moves up to a certain distance, the air pressure pushes the top block 34 to move upward. When the top block 34 moves up, the two rectangular blocks 30 slide outward and fit against the inner wall of the mounting hole. In this way, when the grinding block 22 rotates, the air pressure pushes the rectangular block 30 to move. The rectangular block 30 has a certain pressure on the inner wall of the mounting hole. The grinding block 22 drives the rectangular block 30 to rotate, which can better grind the mounting hole and improve the processing effect.

[0048] Furthermore, the second spring 31 is provided to reset the rectangular block 30. When the moving block 10 moves downward, the rectangular block 30 is no longer subjected to the force of the top block 34 and thus contracts. It should be noted that the second spring 31 causes the two rectangular blocks 30 to have a mutual pulling force. In this way, only when the grinding block 22 is completely moved upward does the top block 34 have sufficient pressure to push the two rectangular blocks 30 apart, thereby ensuring normal operation.

[0049] Furthermore, the moving block 10 drives the rod 16 to move downward, and the rod 16 drives the piston block 15 to move downward. At this time, the air pressure at the upper end of the air cylinder 13 is reduced, and the second air pipe 38 is provided to enable the suction head 37 to absorb dust, and the dust generated when the upper end of the moving block 10 is polished is properly sucked away and falls into the inside of the chute 36. This can reduce the cleaning workload of the staff on the upper end of the moving block 10 and improve the convenience of use. In the later stage, he can clean the dust by opening the cover 8. The setting of the one-way valve 39 can prevent the suction head 37 from jetting and affecting the work.

[0050] Furthermore, the electric rod 4 drives the cross plate 25 to move downward. At this time, the pressure block 6 moves downward under the action of gravity. After the pressure block 6 contacts the steel sheet, the electric rod 4 continues to drive the cross plate 25 to move downward. The pressure block 6 drives the hole-opening rod 28 to move downward. The movement of the cross plate 25 has a downward thrust on the third spring 29. The third spring 29 has a downward thrust on the pressure block 6, and then punches the steel sheet. The hole-opening rod 28 continues to move downward to punch the position of the brake pad mounting hole. At this time, the grinding block 22 moves toward the inside of the rotating rod 20. When the work is completed, the electric rod 4 moves upward to drive the cross plate 25 to move upward. The movement of the cross plate 25 drives the hole-opening rod 28 to press relatively. Block 6 moves upward. It should be noted that at this time the elastic force of the third spring 29 is greater than the elastic force of the first spring 17, so that the cross plate 25 can move upward relative to the pressure block 6, so that the pressure block 6 has a certain pressure on the steel sheet when it moves upward, and the hole-opening rod 28 is retracted into the inside of the pressure block 6. At this time, the grinding block 22 moves up against the waste material and passes through the mounting hole. In this way, when working, since the pressure block 6 always has a certain pressure on the steel sheet, and the hole-opening rod 28 is retracted into the inside of the pressure block 6, the steel sheet is in a stable state. At the same time, the steel sheet is subjected to downward pressure, which increases the friction between the burr at the lower end of the mounting hole and the grinding disc 21, thereby improving the grinding effect of the burr.

Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
