Description

Technical Field

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

[0002] A brake disc refers to a brake force generated by clamping the brake disc with a brake caliper when the vehicle is braking. The material of the brake disc is mainly gray cast iron. In order to meet the needs of production and use, it is often necessary to emboss the brake disc by stamping during production. The Chinese patent announcement number CN112025962B discloses a stamping device for forming automobile brake discs, which includes a base displacement assembly, a mold fixing mechanism, a blanking assembly and a punching machine body. The displacement assembly is fixedly mounted on the top of the base, and a groove is provided on the upper surface of the displacement assembly. The mold fixing mechanism includes a mold fixing block, a mold lifting assembly, a mold assembly, a third slider, two groups of anti-slip plates and several groups of fixing pins. The third slider is slidably connected in the first slide groove of the displacement assembly, has automatic unloading, and reduces labor intensity. The present invention can automatically clean the surface of the brake disc in batches, thereby improving work efficiency.

[0003] In the above-mentioned prior art, brake discs are often stamped using a stamping machine, the principle of which is to use hydraulic or mechanical force to drive the upper die on the stamping end close to the lower die to stamp the workpiece placed on the lower die. When used in 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 to load and unload materials manually, which wastes manpower and is limited by the experience of the staff. 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 use costs. For this reason, a stamping device for brake disc production is proposed. Summary of the invention

[0004] In order to solve the problems of waste of manpower affecting stamping quality and high construction and use costs of mechanical arms during stamping loading and unloading of existing brake discs, the present invention provides a stamping device for brake disc production.

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

[0006] A stamping device for producing brake discs comprises a base, a stamping end is mounted on the base, an upper die is mounted on the stamping end, a lower die is mounted on the base, the lower die is located at the bottom side of the upper die, a movable clamping mechanism for clamping the brake disc during loading and unloading and positioning the brake disc during stamping is mounted on the base, the movable clamping mechanism is located at one side of the lower die, a mounting frame is mounted on the base, a transmission mechanism for driving the movable clamping mechanism to move when the stamping end moves is mounted on the mounting frame, an upper and lower disc mechanism for loading the brake disc is mounted on the mounting frame, the upper and lower disc mechanism is located at the top side of the movable clamping mechanism, a rotating mechanism for loading and unloading the brake disc is mounted on the upper and lower disc mechanism, when stamping the brake disc, multiple brake discs are placed on the upper and lower disc mechanisms, the rotating mechanism is started, and the rotating mechanism pushes the brake disc to the movable clamping mechanism for fixing, and as the stamping process proceeds, the stamping end drives the upper die to approach the lower die, and drives the transmission mechanism in the process The mechanism moves, and the transmission mechanism moves to drive the brake disc on the movable 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 to prevent stamping deformation. At this time, when the stamping end continues to slide, it contacts the top side of the movable clamping mechanism to make the movable clamping mechanism release the clamping of the brake disc, and stamping is performed through the upper and lower dies. After the stamping is completed, the upper die is reset away from the lower die as the stamping end resets, and the lower die ejects the stamped brake disc. At this time, the movable clamping mechanism automatically clamps the brake disc again, and as the stamping end resets, the stamped brake disc is clamped to the bottom side of the upper and lower disc mechanism, and the movement of the upper and lower disc mechanism is triggered. The movement of the upper and lower disc mechanism pushes the next brake disc to be stamped onto the movable clamping mechanism and extrude the stamped brake disc. The stamped brake disc is transmitted to the next process along the conveyor belt, eliminating the frequent manual loading and unloading process. Compared with traditional robotic arms, it has a simple structure and low construction cost.

[0007] Furthermore, the movable clamping mechanism includes a T-shaped slide, which is slidably mounted on the base, a T-shaped slide groove is provided on the base, the T-shaped slide is slidably mounted in the T-shaped slide groove, a fixed ring is installed on the T-shaped slide, a sliding rod is slidably mounted on the fixed ring, an arc end clamp is installed on the sliding rod, an arc end pressure block is installed on the arc end clamp, the arc end pressure 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 end clamp. The T-shaped slide is mounted on the T-shaped slide When sliding on the groove, it drives the fixed ring to slide. When the brake disc falls between the two arc end clamps, the brake disc is clamped under the action of the reset elastic force of the clamping spring, and when the arc end pressure block is squeezed at the stamping end, the sliding rod is driven to slide away from each other on the fixed ring, thereby releasing the clamping of the brake disc, and resets and re-clamps the brake disc after stamping. When the brake disc moves to the bottom side of the upper and lower disc mechanism after stamping, the upper and lower disc mechanism moves to squeeze out the stamped brake disc and clamp the next brake disc to be stamped between the two arc end clamps for continuous stamping process.

[0008] Further, the transmission mechanism includes a connecting plate, which is installed on the stamping end, a driven slide rod is installed on the connecting plate, a transmission plate is slidably installed on the driven slide rod, the transmission plate is installed on the mounting frame, a through hole is opened on the transmission plate, the driven slide rod is slidably installed in the through hole, a limited slide groove is opened on the transmission plate, a limited slider is slidably installed in the limited slide groove, a wedge-shaped slider is slidably installed on the limited slider, a wedge-shaped slide groove is opened on the transmission plate, the wedge-shaped slide groove is connected with the limited slide groove, the wedge-shaped slider is slidably installed in the limited slide groove, a hollow rotating shaft is installed on the limited slider, a rotating plate is rotatably installed on the hollow rotating shaft, a rotating shaft block is rotatably installed on the rotating plate, and the rotating shaft block is installed on the T-shaped slide seat When the punching 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 slider to slide in the wedge-shaped slide groove, and at the same time drives the limiting slider to slide in the limiting slide groove, so that the rotating plate rotates on the hollow rotating shaft and the rotating shaft block, and then drives the T-shaped slide and the brake disc to slide. When the wedge-shaped slider slides to the bottom side of the wedge-shaped slide groove, the driven sliding rod continues to slide, causing the wedge-shaped slider to slide along the inner wall of the wedge-shaped slide groove into the limiting slider. 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, thereby facilitating the positioning of the brake disc and preventing stamping deformation.

[0009] Furthermore, the limit slide block is provided with a sliding cavity, a sliding block is slidably installed in the sliding cavity, the wedge-shaped slide block is installed on the sliding block, a sliding locking shaft is installed on the sliding block, the sliding locking shaft is slidably installed on the hollow rotating shaft, a compression spring is movably sleeved on the sliding locking shaft, one end of the compression spring is installed on the limit slide block, and the other end of the compression spring is installed on the sliding block, and a locking hole block is installed on the transmission plate, which is adapted to the sliding locking shaft. When the wedge slide block slides along the inner wall of the wedge-shaped slide groove, it drives the sliding block to slide in the sliding cavity, thereby facilitating the wedge slide to slide into the limit slide, and in this process, the sliding block slides and drives the sliding locking shaft to slide out on the hollow rotating shaft and slide into the locking hole block, thereby completing the fixation of the structure and preventing the limit slide from resetting and driving the brake disc to reset when the driven slide rod slides, thereby improving the scientificity and practicality of the structure.

[0010] Furthermore, a connecting slide shaft is installed in the T-shaped slide groove, a sliding hole is opened on the T-shaped slide seat, the connecting slide shaft is slidably installed in the sliding hole, a return spring is slidably installed on the connecting slide shaft, one end of the return spring is installed on the base, and the other end of the return spring is installed on the T-shaped slide seat. Through the setting of the return spring, after the stamping is completed, the wedge-shaped slide block is driven to reset during the reset process of the driven slide rod, thereby driving the T-shaped slide seat to reset under the action of the reset elastic force of the return spring, thereby moving the stamped brake disc to the bottom side of the upper and lower disc mechanism.

[0011] Furthermore, a spherical end is provided on the driven slide rod, and the spherical end contacts the wedge-shaped slide block. The setting of the spherical end reduces the contact area between the driven slide rod and the wedge-shaped slide block, facilitates the sliding of the wedge-shaped slide block, and further improves the scientificity and practicality of the structure.

[0012] Furthermore, the upper and lower disc mechanism includes a U-shaped frame, which is installed on the mounting frame. The U-shaped frame is located on one side of the transmission plate, and the U-shaped frame is located on the top side of the fixed ring. A limit rotating rod is rotatably installed on the U-shaped frame, and a turning plate is installed on the limit rotating rod. A friction block is installed on the turning plate, and the friction block is made of rubber material. When the brake disc is placed, the brake disc is fixed by the spacing between adjacent turning plates. When the limit rotating rod rotates, the turning plate is driven to rotate, and the rotation of the turning plate pushes the brake disc to move on the U-shaped frame.

[0013] Furthermore, the rotating mechanism includes a swivel seat, which is installed on a U-shaped frame. A worm is rotatably installed on the swivel seat, a rotating gear is rotatably installed on the U-shaped frame, a worm wheel is installed on the rotating gear, the worm wheel is meshed with the worm, and 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 wheels on both sides to rotate in opposite directions. When the worm wheels on both sides rotate, the rotating gear drives the chain to move, thereby driving the driven gears on both sides to rotate in opposite directions, thereby facilitating the pushing of the brake disc.

[0014] Furthermore, a stepper motor is installed on the rotating seat, the main shaft of the stepper motor is installed on the worm, and an infrared sensing switch is installed on the base. The infrared sensing switch is located on the bottom side of the T-shaped slide. The infrared sensing switch is electrically connected to the stepper motor. Through the setting of the stepper motor, the worm can be rotated to a certain angle, so that the driven gears on both sides can be rotated 90 degrees each time the worm wheel rotates, thereby realizing the ejection of a brake disc. It should be noted that when the fixed ring is located on the bottom side of the U-shaped frame, the infrared sensing switch just senses the T-shaped slide to realize a single triggering of the stepper motor.

[0015] Furthermore, a conveyor belt is installed on the base, and the conveyor belt is located on the bottom side of the U-shaped frame. Through the setting of the conveyor belt, the brake disc that is separated from the movable clamping mechanism after stamping can fall on the conveyor belt and be transmitted to the next process, which is conducive 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] The present invention, through the arrangement of the driven sliding rod, the rotating plate, the arc end clamping block, the turning plate and the like, realizes that when the brake disc is stamped, the movement of the stamping end drives the movement of the rotating plate and the arc end clamping block, thereby automatically clamping the brake disc for loading and unloading before and after stamping, and automatically releasing the clamping during the stamping process, thereby facilitating the positioning of the brake disc and the lower die and preventing stamping deformation, and realizing a continuous stamping process in conjunction with the rotation of the turning plate, thereby eliminating frequent manual loading and unloading and having a simple structure and low construction cost compared to a robotic arm.

[0018] The present invention reduces the contact area between the driven slide rod and the wedge-shaped slide block by setting the spherical end, facilitates the sliding of the wedge-shaped slide block, and further improves the scientificity and practicality of the structure.

[0019] The present invention facilitates the sliding of the wedge-shaped slider into the limit slider by arranging the lock hole block, the sliding block, the sliding lock shaft, etc., and can prevent the limit slider from resetting when the driven slide rod slides, thereby driving the brake disc to reset, thereby improving the scientificity and practicality of the structure.

The rotating mechanism 9 pushes the brake disc to the movable clamping mechanism 6 for fixing. As the stamping process proceeds, the stamping end 2 drives the upper die 3 to approach the lower die 4. During the stamping process, the transmission mechanism 7 is driven 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, thereby realizing the positioning of the brake disc and the die to prevent stamping deformation.
