Description

Technical Field

[0001] The present invention belongs to the technical field of motorcycle brake pad processing, and particularly relates to a punching device for brake pads. Background Art

[0002] Motorcycle brake pads are important components used in the braking system of motorcycles. They are usually composed of friction materials and metal substrates. The friction materials are made of organic materials, semi-metals or ceramics, which can contact and rub against the brake disc during braking to generate frictional force to decelerate the motorcycle; the metal substrates are made of steel, aluminum alloy or copper alloy, providing structural support and heat dissipation functions. The processing steps of motorcycle brake pads are as follows: First, the prepared materials are cut by a cutting device into appropriately sized blocks, and then the metal substrate is formed, usually by stamping or casting processes, to make it the basic shape of the brake pad required. Then, it is punched to facilitate its installation on the brake pad pressing plate through fixing bolts in the later stage. Finally, the friction material is coated on the metal substrate using an adhesive to complete the processing of the entire brake pad.

[0003] When punching brake pads currently, usually the brake pads are first placed on a punching die, and the punching device automatically punches them. However, the existing punching die structure design is relatively simple, only having a single-type die. The punching and discharging of the brake pads are almost carried out simultaneously. If the discharging is not timely, it greatly affects the punching efficiency of the brake pads. And the existing punching die positioning is not accurate enough, greatly reducing the punching efficiency of the brake pads. Summary of the Invention

A machine base is fixedly connected to the other side of the inner wall of the processing table. A first motor is fixedly installed on the top of the machine base.

[0011] Through the above technical solution, the first motor is started. The first motor drives the first connecting shaft to rotate through the output shaft, and then drives the connecting seat, the semi-circular block and the limiting rod to rotate, so that the limiting rod rotates within the corresponding notch. When the first connecting shaft continues to rotate, it drives the hemispherical rotating block to rotate. When the limiting rod rotates 360 degrees, the hemispherical rotating block rotates 90 degrees, and then drives the rotating shaft and the turntable to rotate 90 degrees. While the first connecting shaft rotates, it drives the cam to rotate, so that the protruding part of the cam presses one end of the top of the arc-shaped block, and the arc-shaped block is rotated to drive the second connecting shaft and the first connecting ear to lift upward, and then drives the third connecting shaft to lift upward, so that the third connecting shaft drives the second connecting ear to lift upward through the third connecting ear, the second rotating seat, the fourth connecting ear and the first rotating seat, and then drives the connecting block to rise, so that the connecting block drives the two movable rods and the connecting plate to rise, and then drives the plurality of ejector rods to rise, realizing the ejection of the subsequent brake pad metal substrate, facilitating the feeding mechanism to feed. The rotation and ejection of the brake pad metal substrate can be completed through the first motor, greatly improving the processing efficiency.

[0012] Further, the annular slide bar is slidably connected with the annular chute. A plurality of semi-circular grooves and a plurality of notches are respectively formed on the outer side of the hemispherical rotating block, and the plurality of semi-circular grooves and the plurality of notches are evenly distributed on the hemispherical rotating block. The other end of the second connecting ear is rotatably connected with the connecting block. The other end of the third connecting ear is rotatably connected with the fourth support seat. The first rotating seat is fixedly connected with the second rotating seat through a connecting column. One end of the output shaft of the first motor is fixedly connected with the other end of the first connecting shaft.

[0013] Through the above technical solution, after the semi-circular block rotates 180 degrees, the limiting rod just drives the hemispherical rotating block to rotate 90 degrees. At this time, the semi-circular block just fits with the next semi-circular groove, realizing the limiting effect.

[0014] Further, a positioning groove is formed at the center of the top of the punching die. Two punching holes are formed at the inner edge of the positioning groove at the top of the punching die. A plurality of through ejector holes are formed at the center position of the positioning groove at the top of the punching die. Two through collecting grooves are formed at one end of the punching die. Limiting grooves are respectively formed on both sides of the inner walls of the two collecting grooves in the punching die.

[0015] Through the above technical solution, the positioning groove can position the brake pad metal substrate, providing certain stability when the punching mechanism punches. The chips after the brake pad is punched fall into the corresponding collecting groove through the punching. The two collecting grooves collect the punched chips, facilitating the subsequent discharging mechanism to discharge.

[0016] Further, the feeding mechanism includes a driving roller rotatably connected to one side of the feeding frame, and a plurality of driven rollers rotatably connected to the other side of the feeding frame near the driving roller. A feeding belt is sleeved between the driving roller and the plurality of driven rollers. A plurality of evenly distributed positioning feeding plates are fixedly connected to the feeding belt. A second motor is fixedly connected to one side of the front end of the feeding frame, and the rear end of the output shaft of the second motor is fixedly connected to the front end of the driving roller.

[0017] Through the above technical solution, when feeding the metal base material of the brake pad, the staff places the metal base material of the brake pad into the positioning feeding plate at one end of the feeding belt. There are holes on the positioning feeding plate with the same area as the metal base material of the brake pad, which is convenient for the subsequent material transfer mechanism to feed it. Start the second motor, so that the second motor drives the driving roller to rotate through the output shaft, and cooperate with a plurality of driven rollers to drive the feeding belt to drive, realizing the feeding of the metal base material of the brake pad.

[0018] Further, the material transfer mechanism includes a first support frame fixedly connected to the front end of the top of the processing table. A fixing plate is fixedly connected to the top of the first support frame. An arc-shaped groove is formed in the fixing plate. A first slide rail is fixedly connected to one side of the first support frame. A slider is slidably connected to the first slide rail. A third motor is fixedly installed at the other side of the top of the first support frame near the fixing plate. One end of the output shaft of the third motor is fixedly connected to a movable ear. The upper end of the movable ear is rotatably connected to a connecting rod. One end of the outer wall of the connecting rod is rotatably connected to a second slide rail. The other end of the outer wall of the connecting rod slides in the arc-shaped groove. The second slide rail is slidably connected to the slider. The bottom end of the second slide rail is fixedly connected to a mounting plate. A plurality of electromagnetic blocks are installed at the bottom of the mounting plate. Buffer sleeves are installed at the outer sides of the corresponding electromagnetic blocks at the bottom of the mounting plate.

[0019] Through the above technical solution, when the metal base material of the brake pad is conveyed to the other end through the feeding belt, start the third motor, so that the third motor drives the movable ear to rotate through the output shaft, so that the movable ear provides a swinging force for the second slide rail, so that the second slide rail slides downward under the limiting action of the slider, and at the same time the slider slides on the first slide rail. The downward sliding of the second slide rail drives the mounting plate to move downward, and then drives a plurality of electromagnetic blocks and the corresponding buffer sleeves to move downward. The plurality of buffer sleeves first contact the surface of the metal base material of the brake pad to achieve a buffering effect. The second slide rail slides downward again to drive the plurality of electromagnetic blocks to contact the surface of the metal base material of the brake pad to suck the surface of the metal base material of the brake pad. The output shaft of the third motor rotates in reverse, and places the metal base material of the brake pad on the feeding belt into the positioning groove on the punching die. The third motor performs reciprocating driving, so as to realize the orderly feeding of the metal base material of the brake pad. It not only has high efficiency, but also does not require manual feeding, preventing the subsequent punching mechanism from accidentally injuring the staff during punching.

[0020] Further, the punching mechanism includes a second support frame fixedly connected to one side of the top of the processing table. A hydraulic cylinder is fixedly installed on the top of the second support frame. The bottom end of the piston of the hydraulic cylinder is fixedly connected to a first punching plate. Four corners of the bottom of the first punching plate are fixedly connected with first springs. The bottoms of the plurality of first springs are fixedly connected to a second punching plate. Four corners of the top of the second punching plate are fixedly connected with guide rods. The plurality of guide rods are respectively located inside the corresponding first springs and penetrate through the first punching plate. Two mounting seats are fixedly connected to the center of the bottom of the first punching plate. Punching needles are installed at the bottoms of the two mounting seats.

[0021] Through the above technical solution, when the brake pad metal substrate on the punching die rotates to below the two punching needles, the hydraulic cylinder is started at this time, so that the hydraulic cylinder pushes the first punching plate, a plurality of first springs, a plurality of guide rods and the second punching plate through the piston, so that the second punching plate first fits with the top of the punching die and also fits with the surface of the brake pad metal substrate at the same time. When the piston of the hydraulic cylinder is pushed downward again, it drives the two mounting seats and the corresponding punching needles to move downward, realizing punching the brake pad metal substrate with the two punching needles.

[0022] Further, the material discharging mechanism includes two push blocks arranged in the punching die. The two push blocks are respectively slidably connected to the corresponding collecting grooves. The outer ends of both ends of the two push blocks are fixedly connected with limiting blocks. The plurality of limiting blocks are respectively slidably connected to the corresponding limiting grooves. One ends of the two limiting blocks are fixedly connected with push rods. Second springs are fixedly installed at one ends of the two limiting blocks and on the outer sides of the corresponding push rods. One ends of the two push rods are fixedly connected with a first push plate.

[0023] Through the above technical solution, when the first push plate is pushed, it drives the two push rods to push, so that the two push rods respectively drive the push blocks connected thereto to push, realizing pushing the punching chips in the collecting grooves onto the corresponding discharging racks. After the pushing mechanism finishes pushing, the two second springs reset, driving the corresponding push blocks and push rods to reset, facilitating subsequent material discharging treatment again and preventing the chips from accumulating together and affecting the processing of the brake pads.

[0024] Further, the pushing mechanism includes a first fixed seat fixedly connected to one side of the rear end of the top of the processing table. A first fixed ear is fixedly connected to the top of the first fixed seat. A first air cylinder is fixedly installed at the bottom of one end of the first fixed ear. One end of the piston of the first air cylinder is fixedly connected to a second push plate.

[0025] Through the above technical solution, when the punching die rotates 90 degrees again through the turntable, the first air cylinder is started at this time, so that the first air cylinder pushes the second push plate through the piston, and the second push plate pushes the first push plate, realizing the discharging treatment of the two collecting grooves.

[0026] Further, the blanking mechanism includes a second fixed seat fixedly connected to the other side of the front end of the top of the processing table. A second fixed ear is fixedly connected to the top of the second fixed seat. A second air cylinder is fixedly installed at the bottom of one end of the second fixed ear. One end of the piston of the second air cylinder is fixedly connected to a third push plate, and the third push plate is located above one of the punching dies.

[0027] Through the above technical solution, after the punching die rotates 90 degrees through the turntable, at this time, the rotating ejection mechanism ejects the punched brake pad metal substrate, so that it is located above the punching die. The second air cylinder is started, so that the second air cylinder pushes the third push plate through the piston, so that the third push plate pushes the brake pad metal substrate, and the brake pad metal substrate is pushed onto the blanking rack, completing the blanking of the brake pad metal substrate.

[0028] The beneficial effects of the present invention are as follows: (1) By designing the punching die and using the positioning groove on the punching die, the brake pads can be quickly positioned, improving the punching accuracy of the brake pads. At the same time, there are multiple punching dies, which can perform multiple processes simultaneously, loading, punching and discharging the brake pads, and do not affect the overall processing process, improving the overall processing efficiency. (2) By designing the feeding mechanism, the material transfer mechanism and the rotating ejection mechanism, the three mechanisms cooperate with each other, and the brake pads can be loaded orderly without manual loading by the staff, preventing the stamping equipment from accidentally injuring the staff. At the same time, the processing efficiency of the device is greatly improved. In the rotating ejection mechanism, only one motor is needed to achieve the rotating and ejecting effects, and the functionality is strong. (3) Through the punching mechanism, the discharging mechanism and the blanking mechanism of the present invention, cooperating with the rotating ejection mechanism, the chips in the punching die can be discharged orderly, preventing blockage and affecting subsequent punching. Cooperating with the rotating ejection mechanism, the punched brake pads can be blanked. Each mechanism cooperates with each other, the rhythm is compact, and there is no need for manual loading and unloading by the staff, and the efficiency is high. Description of the Drawings

One end of the outer wall of the connecting rod 607 is rotatably connected with a second slide rail 606. The other end of the outer wall of the connecting rod 607 slides in the arc-shaped groove 603. The second slide rail 606 is slidably connected with the slider 605. The bottom end of the second slide rail 606 is fixedly connected with a mounting plate 610. A plurality of electromagnetic blocks 611 are installed at the bottom of the mounting plate 610. Buffer sleeves 612 are installed at the bottom of the mounting plate 610 and at positions outside the corresponding electromagnetic blocks 611. When the metal substrate of the brake pad is conveyed to the other end through the feeding belt 503, the third motor 609 is started, so that the third motor 609 drives the movable ear 608 to rotate through the output shaft, so that the movable ear 608 provides a swinging force for the second slide rail 606, so that the second slide rail 606 slides downward under the limiting action of the slider 605. At the same time, the slider 605 slides on the first slide rail 604. The downward sliding of the second slide rail 606 drives the mounting plate 610 to move downward, thereby driving a plurality of electromagnetic blocks 611 and the corresponding buffer sleeves 612 to move downward. The plurality of buffer sleeves 612 initially contact the surface of the metal substrate of the brake pad to achieve a buffering effect. The second slide rail 606 slides downward again to drive a plurality of electromagnetic blocks 611 to contact the surface of the metal substrate of the brake pad to achieve adsorption and fixation on the surface of the metal substrate of the brake pad. The output shaft of the third motor 609 rotates in reverse to place the metal substrate of the brake pad on the feeding belt 503 into the positioning groove 41 on the punching die 4. The third motor 609 performs reciprocating driving, so as to realize the orderly feeding of the metal substrate of the brake pad, which not only has high efficiency and does not require manual feeding, but also prevents the subsequent punching mechanism 7 from accidentally injuring the staff during operation.

[0048] As Figures 1-12As shown in the figure, a punching mechanism 7 is fixedly installed on one side of the top of the processing table 1. The punching mechanism 7 includes a second support frame 701 fixedly connected to one side of the top of the processing table 1. A hydraulic cylinder 702 is fixedly installed on the top of the second support frame 701. The bottom end of the piston of the hydraulic cylinder 702 is fixedly connected to a first punching plate 703. Four corners of the bottom of the first punching plate 703 are fixedly connected with first springs 704. The bottoms of the plurality of first springs 704 are fixedly connected to a second punching plate 705. Four corners of the top of the second punching plate 705 are fixedly connected with guide rods 706. The plurality of guide rods 706 are respectively located inside the corresponding first springs 704 and penetrate through the first punching plate 703. Two mounting seats 707 are fixedly connected to the center of the bottom of the first punching plate 703. Punching needles 708 are installed at the bottoms of the two mounting seats 707. When the brake pad metal substrate on the punching die 4 rotates to below the two punching needles 708, the hydraulic cylinder 702 is started at this time, so that the hydraulic cylinder 702 pushes the first punching plate 703, the plurality of first springs 704, the plurality of guide rods 706 and the second punching plate 705 through the piston, so that the second punching plate 705 first fits with the top of the punching die 4 and at the same time fits with the surface of the brake pad metal substrate. When the piston of the hydraulic cylinder 702 is pushed downward again, it drives the two mounting seats 707 and the corresponding punching needles 708 to move downward, realizing punching the brake pad metal substrate with the two punching needles 708.

[0049] As Figures 1-8 shown, a discharging mechanism 8 is installed on each of the plurality of punching dies 4. The discharging mechanism 8 includes two pushing blocks 801 arranged in the punching die 4. The two pushing blocks 801 are respectively slidably connected to the corresponding collecting grooves 44. Both ends of the outer sides of the two pushing blocks 801 are fixedly connected with limiting blocks 802. The plurality of limiting blocks 802 are respectively slidably connected to the corresponding limiting grooves 45. One ends of the two limiting blocks 802 are fixedly connected with push rods 803. Second springs 804 are fixedly installed at one ends of the two limiting blocks 802 and located outside the corresponding push rods 803. One ends of the two push rods 803 are fixedly connected with a first pushing plate 805. When the first pushing plate 805 is pushed, it drives the two push rods 803 to be pushed, so that the two push rods 803 respectively drive the pushing blocks 801 connected thereto to be pushed, realizing pushing the chips in the collecting groove 44 onto the corresponding discharging racks 11. After the pushing mechanism 9 finishes pushing, the two second springs 804 are reset, driving the corresponding pushing blocks 801 and push rods 803 to be reset, facilitating subsequent discharging treatment again and preventing the chips from accumulating together and affecting the processing of the brake pads.

[0050] As Figures 1-13As shown in the figure, a pushing mechanism 9 is fixedly installed on one side of the rear end of the top of the processing table 1. The pushing mechanism 9 includes a first fixed seat 901 fixedly connected to one side of the rear end of the top of the processing table 1. A first fixed ear 902 is fixedly connected to the top of the first fixed seat 901. A first air cylinder 903 is fixedly installed at the bottom of one end of the first fixed ear 902. One end of the piston of the first air cylinder 903 is fixedly connected to a second push plate 904. When the punching die 4 rotates another 90 degrees through the turntable 304, at this time, the first air cylinder 903 is started, so that the first air cylinder 903 pushes the second push plate 904 through the piston, and the second push plate 904 pushes the first push plate 805, realizing the discharging process of the two collecting grooves 44.

[0051] As Figures 1-13 shown in the figure, a blanking mechanism 10 is fixedly installed on the other side of the front end of the top of the processing table 1. A discharging rack 11 is fixedly connected to the center of the rear end of the top of the processing table 1. A blanking rack 12 is fixedly connected to the other side of the center of the top of the processing table 1. The blanking mechanism 10 includes a second fixed seat 1001 fixedly connected to the other side of the front end of the top of the processing table 1. A second fixed ear 1002 is fixedly connected to the top of the second fixed seat 1001. A second air cylinder 1003 is fixedly installed at the bottom of one end of the second fixed ear 1002. One end of the piston of the second air cylinder 1003 is fixedly connected to a third push plate 1004. The third push plate 1004 is located on the top of one of the punching dies 4. After the punching die 4 rotates another 90 degrees through the turntable 304, at this time, the rotary ejecting mechanism 3 ejects the brake pad metal substrate, so that it is located above the punching die 4. The second air cylinder 1003 is started, so that the second air cylinder 1003 pushes the third push plate 1004 through the piston, and the third push plate 1004 pushes the brake pad metal substrate, so that the brake pad metal substrate is pushed onto the blanking rack 12, completing the blanking of the brake pad metal substrate.

[0052] The working principle of this embodiment is as follows. The staff places the brake pad metal substrate into the positioning feeding plate 504 at one end of the feeding belt 503, and starts the second motor 505, so that the second motor 505 drives the driving roller 501 to rotate through the output shaft, and cooperates with a plurality of driven rollers 502 to drive the feeding belt 503 to transmit, realizing the feeding of the brake pad metal substrate;

[0053] When the metal substrate of the brake pad is sent to the other end of the feeding belt 503, the third motor 609 is started, so that the third motor 609 drives the movable ear 608 to rotate through the output shaft, so that the movable ear 608 provides a swinging force to the second slide rail 606, so that the second slide rail 606 slides downward under the limiting action of the slider 605. At the same time, the slider 605 slides on the first slide rail 604. The downward sliding of the second slide rail 606 drives the mounting plate 610 to move downward, and then drives a plurality of electromagnetic blocks 611 to contact the surface of the metal substrate of the brake pad, realizing the adsorption and fixation of the surface of the metal substrate of the brake pad. Then, under the action of the third motor 609, the adsorbed metal substrate of the brake pad is placed into the positioning groove 41 on the punching die 4;

[0054] At this time, the first motor 331 is started. The first motor 331 drives the first connecting shaft 308 to rotate, and then drives the connecting seat 309, the half-ring block 310 and the limiting rod 311 to rotate, so that the limiting rod 311 rotates in the corresponding notch 3062. When the first connecting shaft 308 continues to rotate, it drives the hemispherical rotating block 306 to rotate. When the limiting rod 311 rotates 360 degrees, the hemispherical rotating block 306 rotates 90 degrees, and then drives the rotating shaft 302 and the turntable 304 to rotate 90 degrees. Through the turntable 304, the placed metal substrate of the brake pad is rotated 90 degrees (at this time, another adjacent punching die 4 is rotated under the transfer mechanism 6 to prepare for feeding), so that it rotates to the position below the two punching needles 708. At this time, the hydraulic cylinder 702 is started, so that the hydraulic cylinder 702 pushes the first punching plate 703, a plurality of first springs 704, a plurality of guide rods 706 and the second punching plate 705 through the piston, so that the second punching plate 705 first fits with the top of the punching die 4 and also fits with the surface of the metal substrate of the brake pad. When the piston of the hydraulic cylinder 702 is pushed downward again, it drives the two mounting seats 707 and the corresponding punching needles 708 to move downward, realizing the punching of the metal substrate of the brake pad by the two punching needles 708;

[0055] Then start the first motor 331 to rotate 90 degrees again through the turntable 304, and rotate the punched metal substrate of the brake pad to the position close to the pushing mechanism 9 (at this time, another adjacent punching die 4 is rotated under the punching mechanism 7 to prepare for punching). At this time, the first cylinder 903 is started, so that the first cylinder 903 pushes the second push plate 904 through the piston, so that the second push plate 904 pushes the first push plate 805, and then pushes the two push rods 803, so that the two push rods 803 drive the push blocks 801 connected to them to push respectively, realizing the pushing of the chips in the collecting groove 44 to the corresponding discharge rack 11;

[0056] Restart the first motor 331 to rotate the turntable 304 by another 90 degrees, rotating the punched brake pad metal substrate to a position close to the blanking mechanism 10 (at this time, another nearby punching die 4 is rotated to be close to the pushing mechanism 9 for discharging). At this time, while the driven first motor 331 drives the first connecting shaft 308 to rotate, it also drives the cam 312 to rotate, causing the protruding part of the cam 312 to squeeze one end of the top of the arc-shaped block 315, causing the arc-shaped block 315 to be rotated to drive the second connecting shaft 314 and the first connecting ear 316 to lift upward, and then driving the third connecting shaft 317 to lift upward. The third connecting shaft 317 drives the second connecting ear 324 to lift upward through the third connecting ear 326, the second rotating seat 329, the fourth connecting ear 327, and the first rotating seat 328, and then drives the connecting block 322 to lift upward, causing the connecting block 322 to drive the two movable rods 319 and the connecting plate 320 to lift upward, and then driving the multiple ejector rods 321 to lift upward, realizing the ejection of the punched brake pad metal substrate. Start the second cylinder 1003, so that the second cylinder 1003 pushes the third push plate 1004 through the piston, and the third push plate 1004 pushes the brake pad metal substrate, pushing the brake pad metal substrate onto the blanking rack 12, realizing the blanking of the brake pad metal substrate.

[0057] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
