Description

Technical Field

[0001] The present invention relates to the technical field of stamping devices, and particularly relates to a stamping device for producing brake discs. Background Art

[0002] A brake disc refers to a component that generates braking force when the vehicle brakes by clamping the brake disc with a brake caliper. Its main material is gray cast iron. To meet the production and usage requirements, during the production of brake discs, embossing is often required through stamping. The patent with the Chinese patent publication number CN112025962B discloses a stamping device for forming automotive brake discs, which includes a base displacement component, a die fixing mechanism, a blanking component, and a stamping machine body. The displacement component is fixedly installed on the top of the base, and a groove is provided on the upper surface of the displacement component. The die fixing mechanism includes a die fixing block, a die lifting component, a die component, a third slider, two anti - detachment plates, and several groups of fixing pins. The third slider is slidably connected in the first chute of the displacement component, which has the advantages of automatic unloading, reducing labor intensity. The present invention can batch - clean the surface of brake discs automatically and improve work efficiency.

[0003] In the above - mentioned prior art, during the stamping of brake discs, it is often carried out by a stamping machine. Its principle is to drive the upper die on the stamping end to approach the lower die by hydraulic or mechanical force to stamp and form the workpiece placed on the lower die. When applied to the stamping process of brake discs, the brake disc needs to be placed on the lower die before stamping and taken out after stamping. There are mainly two methods. One is manual loading and unloading, which wastes manpower and is limited by the experience of the staff, and there is a possibility that the brake disc is not aligned with the lower die, affecting the stamping quality. The other is to use a robotic arm to replace manual loading and unloading, which has high construction and usage costs. Therefore, a stamping device for producing brake discs is proposed. Summary of the Invention

[0004] To solve the problems that in the prior art, during the stamping loading and unloading of brake discs, manual operation wastes manpower and affects stamping quality, and using a robotic arm has high construction and usage costs, the present invention provides a stamping device for producing brake discs.

[0005] The present invention specifically adopts the following technical solutions to achieve the above - mentioned purpose:

[0006] A stamping device for manufacturing brake discs, comprising a base, on which a stamping end is installed, an upper die is installed on the stamping end, a lower die is installed on the base, the lower die is located on the bottom side of the upper die, an active clamping mechanism for clamping the brake disc during loading and unloading and positioning the brake disc during stamping is installed on the base, the active clamping mechanism is located on one side of the lower die, a mounting frame is installed on the base, a transmission mechanism for driving the active clamping mechanism to move when the stamping end moves is installed on the mounting frame, a disc loading and unloading mechanism for loading the brake disc is installed on the mounting frame, the disc loading and unloading mechanism is located on the top side of the active clamping mechanism, a rotating mechanism for loading and unloading the brake disc is installed on the disc loading and unloading mechanism. When stamping the brake disc, a plurality of brake discs are placed on the disc loading and unloading mechanism, the rotating mechanism is started, and the rotating mechanism pushes the brake disc onto the active clamping mechanism for fixation. As the stamping process progresses, when the stamping end drives the upper die to approach the lower die, it drives the transmission mechanism to move. The movement of the transmission mechanism drives the brake disc on the active clamping mechanism to slide to the top side of the lower die and stop, thereby realizing the positioning of the brake disc and the die, preventing stamping deformation. At this time, when the stamping end continues to slide, it contacts the top side of the active clamping mechanism, causing the active clamping mechanism to release the clamping of the brake disc, and stamping is performed through the upper die and the lower die. After stamping, the upper die returns away from the lower die with the stamping end. The lower die ejects the stamped brake disc. At this time, the active clamping mechanism automatically clamps the brake disc again, and with the return of the stamping end, the stamped brake disc is clamped to the bottom side of the disc loading and unloading mechanism, and the disc loading and unloading mechanism is triggered to move. The movement of the disc loading and unloading mechanism pushes the next brake disc to be stamped onto the active clamping mechanism and extrudes the stamped brake disc. The stamped brake disc is transported to the next process along the conveyor belt, eliminating the need for manual frequent loading and unloading. Compared with the traditional robotic arm, the structure is simple and the construction cost is low.

[0007] Further, the active clamping mechanism includes a T-shaped sliding seat, which is slidably installed on the base. A T-shaped sliding groove is formed on the base, and the T-shaped sliding seat is slidably installed in the T-shaped sliding groove. A fixed ring is installed on the T-shaped sliding seat. A sliding rod is slidably installed on the fixed ring. An arc-shaped end clamping block is installed on the sliding rod. An arc-shaped end pressing block is installed on the arc-shaped end clamping block. The arc-shaped end pressing block is located on the bottom side of the stamping end. A clamping spring is movably sleeved on the sliding rod. One end of the clamping spring is installed on the fixed ring, and the other end of the clamping spring is installed on the arc-shaped end clamping block. When the T-shaped sliding seat slides on the T-shaped sliding groove, it drives the fixed ring to slide. When the brake disc falls between the two arc-shaped end clamping blocks, it is clamped by the restoring elastic force of the clamping spring. And when the stamping end presses the arc-shaped end pressing block, it drives the sliding rod to slide away from each other on the fixed ring, thereby releasing the clamping of the brake disc, and clamping the brake disc again after stamping. When the stamped brake disc moves to the bottom side of the disc loading and unloading mechanism, the movement of the disc loading and unloading mechanism extrudes the stamped brake disc and clamps the next brake disc to be stamped between the two arc-shaped end clamping blocks for continuous stamping process.

[0008] Further, the transmission mechanism includes a connecting plate which is mounted on the stamping end. A driven sliding rod is mounted on the connecting plate. A transmission plate is slidably mounted on the driven sliding rod. The transmission plate is mounted on the mounting frame. A through hole is formed in the transmission plate, and the driven sliding rod is slidably mounted in the through hole. A limiting sliding groove is formed in the transmission plate, and a limiting sliding block is slidably mounted in the limiting sliding groove. A wedge-shaped sliding block is slidably mounted on the limiting sliding block. A wedge-shaped sliding groove is formed in the transmission plate, and the wedge-shaped sliding groove communicates with the limiting sliding groove. The wedge-shaped sliding block is slidably mounted in the limiting sliding groove. A hollow rotating shaft is mounted on the limiting sliding block. A rotating plate is rotatably mounted on the hollow rotating shaft. A rotating shaft block is rotatably mounted on the rotating plate. The rotating shaft block is mounted on the T-shaped sliding seat. When the stamping end slides close to the lower die, it drives the connecting plate to slide. The sliding of the connecting plate drives the driven sliding rod to slide on the transmission plate. The sliding of the driven sliding rod drives the wedge-shaped sliding block to slide in the wedge-shaped sliding groove, and at the same time drives the limiting sliding block to slide in the limiting sliding groove, so that the rotating plate rotates on the hollow rotating shaft and the rotating shaft block, and further drives the T-shaped sliding seat and the brake disc to slide. When the wedge-shaped sliding block slides to the bottom side of the wedge-shaped sliding groove, when the driven sliding rod continues to slide, the wedge-shaped sliding block slides along the inner wall of the wedge-shaped sliding groove into the limiting sliding block. At this time, the clamped brake disc just slides to the top side of the lower die. When the driven sliding rod continues to slide in the through hole, the brake disc no longer moves, which facilitates the positioning of the brake disc and prevents stamping deformation.

[0009] Further, a sliding cavity is formed in the limiting sliding block, and a sliding block is slidably mounted in the sliding cavity. The wedge-shaped sliding block is mounted on the sliding block. A sliding locking shaft is mounted on the sliding block. The sliding locking shaft is slidably mounted on the hollow rotating shaft. A compression spring is movably sleeved on the sliding locking shaft. One end of the compression spring is mounted on the limiting sliding block, and the other end of the compression spring is mounted on the sliding block. A locking hole block is mounted on the transmission plate, and the locking hole block is adapted to the sliding locking shaft. When the wedge-shaped sliding block slides along the inner wall of the wedge-shaped sliding groove, it drives the sliding block to slide in the sliding cavity, which facilitates the wedge-shaped sliding block to slide into the limiting sliding block. And in this process, the sliding of the sliding block drives the sliding locking shaft to slide out on the hollow rotating shaft and slide into the locking hole block, so as to complete the fixation of the structure, prevent the limiting sliding block from resetting to drive the brake disc to reset when the driven sliding rod slides, and improve the scientificity and practicality of the structure.

[0010] Further, a connecting sliding shaft is mounted in the T-shaped sliding groove. A sliding hole is formed in the T-shaped sliding seat, and the connecting sliding shaft is slidably mounted in the sliding hole. A return spring is slidably mounted on the connecting sliding shaft. One end of the return spring is mounted on the base, and the other end of the return spring is mounted on the T-shaped sliding seat. Through the arrangement of the return spring, after the stamping is completed, when the driven sliding rod resets, it drives the wedge-shaped sliding block to reset, and thus drives the T-shaped sliding seat to reset under the reset elastic force of the return spring, so as to move the stamped brake disc to the bottom side of the upper and lower disc mechanism.

[0011] Further, a spherical end is provided on the driven sliding rod. The spherical end is in contact with the wedge-shaped slider. Through the provision of the spherical end, the contact area between the driven sliding rod and the wedge-shaped slider is reduced, facilitating the sliding of the wedge-shaped slider and further improving the scientificity and practicality of the structure.

[0012] Further, the upper and lower disc mechanism includes a U-shaped frame. The U-shaped frame is installed on the mounting frame. The U-shaped frame is located on one side of the transmission plate and on the top side of the fixed ring. A limiting rotating rod is rotatably installed on the U-shaped frame. A rotating vane is installed on the limiting rotating rod. A friction block is installed on the rotating vane. The friction block is made of rubber material. When placing the brake disc, the brake disc is fixed by the spacing between adjacent rotating vanes. When the limiting rotating rod rotates, it drives the rotating vane to rotate, and the rotating vane rotates to push the brake disc to move on the U-shaped frame.

[0013] Further, the rotating mechanism includes a rotating base. The rotating base is installed on the U-shaped frame. A worm is rotatably installed on the rotating base. A rotating gear is rotatably installed on the U-shaped frame. A worm gear is installed on the rotating gear. The worm gear meshes with the worm. A driven gear is installed on the limiting rotating rod. The driven gear and the rotating gear are meshed with the same chain. When the worm rotates, it drives the worm gears on both sides to rotate in opposite directions. When the worm gears on both sides rotate, they drive the chain to move through the rotating gear, thereby driving the driven gears on both sides to rotate in opposite directions, thus facilitating the pushing of the brake disc.

[0014] Further, a stepping motor is installed on the rotating base. The main shaft of the stepping motor is installed on the worm. An infrared induction switch is installed on the base. The infrared induction switch is located on the bottom side of the T-shaped sliding seat. The infrared induction switch is electrically connected to the stepping motor. Through the provision of the stepping motor, it is convenient for the worm to rotate a certain angle, so that each time the worm gear rotates, it drives the driven gears on both sides to rotate 90 degrees, and then a brake disc is pushed out. It should be noted that the infrared induction switch just senses the T-shaped sliding seat when the fixed ring is located at the bottom side of the U-shaped frame to achieve a single trigger of the stepping motor.

[0015] Further, a conveyor belt is installed on the base. The conveyor belt is located on the bottom side of the U-shaped frame. Through the provision of the conveyor belt, it is convenient for the brake disc that has been stamped and separated from the movable clamping mechanism to fall on the conveyor belt and be transported to the next process, which is beneficial to the continuous stamping process and improves the convenience of use of the structure.

[0016] The beneficial effects of the present invention are as follows:

[0017] In the present invention, through the settings of a driven slide rod, a rotating plate, an arc-end clamping block, a rotating page plate, etc., when stamping a brake disc, the movement of the stamping end drives the movement of the rotating plate and the arc-end clamping block, realizing automatic clamping of the brake disc for loading and unloading before and after stamping, and automatically releasing the clamping during the stamping process, facilitating the positioning of the brake disc with the lower die, preventing stamping deformation, and realizing a continuous stamping process in cooperation with the rotation of the rotating page plate. This saves the need for frequent manual loading and unloading, and compared with a robotic arm, the structure is simple and the construction cost is low.

[0018] In the present invention, through the setting of the spherical end, the contact area between the driven slide rod and the wedge-shaped slider is reduced, facilitating the sliding of the wedge-shaped slider, and further improving the scientificity and practicality of the structure.

[0019] In the present invention, through the settings of a lock hole block, a sliding block, a sliding lock shaft, etc., it is convenient for the wedge-shaped slider to slide into the limit slider, and at the same time, it can prevent the limit slider from resetting and driving the brake disc to reset when the driven slide rod slides, improving the scientificity and practicality of the structure.

When stamping the brake disc, a plurality of brake discs are placed on the upper and lower disc mechanism 8, the rotating mechanism 9 is started, and the rotating mechanism 9 pushes the brake disc onto the movable clamping mechanism 6 and fixes it. As the stamping process progresses, when the stamping end 2 drives the upper die 3 to approach the lower die 4, it drives the transmission mechanism 7 to move. The movement of the transmission mechanism 7 drives the brake disc on the movable clamping mechanism 6 to slide to the top side of the lower die 4 and stop, so as to realize the positioning of the brake disc and the mold and prevent stamping deformation. At this time, when the stamping end 2 continues to slide, it contacts the top side of the movable clamping mechanism 6, causing the movable clamping mechanism 6 to release the clamping of the brake disc. The brake disc is stamped by the upper die 3 and the lower die 4. After stamping, the upper die 3 returns away from the lower die 4 with the stamping end 2, and the lower die 4 ejects the stamped brake disc. At this time, the movable clamping mechanism 6 automatically clamps the brake disc again, and clamps the stamped brake disc to the bottom side of the upper and lower disc mechanism 8 with the reset of the stamping end 2, and triggers the movement of the upper and lower disc mechanism 8. The movement of the upper and lower disc mechanism 8 pushes the next brake disc to be stamped onto the movable clamping mechanism 6 and extrudes the stamped brake disc. The stamped brake disc is transported to the next process along the conveyor belt 10, eliminating the need for manual frequent loading and unloading.

An arc-end pressing block 606 is mounted on the arc-end clamping block 605. The arc-end pressing block 606 is located at the bottom side of the stamping end 2. A clamping spring 607 is movably sleeved on the sliding rod 604. One end of the clamping spring 607 is mounted on the fixed ring 603, and the other end of the clamping spring 607 is mounted on the arc-end clamping block 605. When the T-shaped sliding seat 601 slides on the T-shaped sliding groove 602, it drives the fixed ring 603 to slide. When the brake disc falls between the two arc-end clamping blocks 605, the brake disc is clamped under the reset elastic force of the clamping spring 607. And when the stamping end 2 presses the arc-end pressing block 606, it drives the sliding rod 604 to slide away from each other on the fixed ring 603, thereby releasing the clamping of the brake disc, and resetting to clamp the brake disc again after the stamping is completed.

The sliding of the connecting plate 701 drives the driven sliding rod 702 to slide on the transmission plate 703. The sliding of the driven sliding rod 702 drives the wedge-shaped sliding block 706 to slide in the wedge-shaped sliding groove 707, and at the same time drives the limiting sliding block 705 to slide in the limiting sliding groove 704, so that the rotating plate 710 rotates on the hollow rotating shaft 709 and the rotating shaft block 711, and further drives the T-shaped sliding seat 601 and the brake disc to slide. When the wedge-shaped sliding block 706 slides to the bottom side of the wedge-shaped sliding groove 707, when the driven sliding rod 702 continues to slide, the wedge-shaped sliding block 706 slides along the inner wall of the wedge-shaped sliding groove 707 into the limiting sliding block 705. At this time, the clamped brake disc just slides to the top side of the lower die 4. When the driven sliding rod 702 continues to slide in the through hole 708, the brake disc no longer moves, which facilitates the positioning of the brake disc and prevents stamping deformation.

[0037] Refer to Figures 1-6, in the embodiment of the present invention, a sliding cavity 712 is formed in the limit slider 705. A sliding block 713 is slidably installed in the sliding cavity 712.

A lock hole block 716 is installed on the transmission plate 703. The lock hole block 716 is adapted to the sliding lock shaft 715. When the wedge-shaped slider 706 slides along the inner wall of the wedge-shaped chute 707, it drives the sliding block 713 to slide in the sliding cavity 712, so as to facilitate the wedge-shaped slider 706 to slide into the limit slider 705. During this process, the sliding of the sliding block 713 drives the sliding lock shaft 715 to slide out on the hollow rotating shaft 709 and slide into the lock hole block 716, thereby completing the fixation of the structure and preventing the limit slider 705 from resetting to drive the brake disc to reset when the driven sliding rod 702 slides, improving the scientificity and practicality of the structure.

One end of the return spring 719 is installed on the base 1, and the other end of the return spring 719 is installed on the T-shaped sliding seat 601. Through the arrangement of the return spring 719, it is realized that during the reset process of the driven sliding rod 702 after stamping, the wedge-shaped slider 706 is driven to reset, and thus the T-shaped sliding seat 601 is driven to reset under the reset elastic force of the return spring 719, so as to move the stamped brake disc to the bottom side of the upper and lower disc mechanism 8.

When the worm 902 rotates, it drives the worm gears 904 on both sides to rotate in opposite directions. When the worm gears 904 on both sides rotate, they drive the chain 906 to move through the rotating gear 903, thereby driving the driven gears 905 on both sides to rotate in opposite directions, thus facilitating the pushing of the brake disc.

[0042] Refer to Figures 1-8 , in the embodiment of the present invention, a stepping motor 907 is installed on the rotating seat 901.
