Description

A brake pad backplate blank stamping equipment Technical Field

[0001] This invention relates to the field of brake pad backplate production technology, specifically to a brake pad backplate blank stamping equipment. Background Technology

[0002] Brake pads, also known as brake discs, are safety components in automotive braking systems that use friction to decelerate vehicles. They consist of a steel plate, a heat insulation layer, and friction blocks, and require regular inspection and replacement to ensure safety. In the production and processing of brake pad backing plates, stamping is one of the core processes. However, existing brake pad backing plate blank stamping equipment encounters many problems in practical use.

[0003] Chinese patent CN115815427B discloses a brake pad stamping device, belonging to the field of brake pad processing equipment. It includes an upper die base and a lower die base, with an upper die and a lower die fitted between them. A moving mechanism is also fitted between the upper and lower die bases to control the movement of the upper and lower dies. An upper die connecting mechanism is also fitted between the upper die base and the upper die. U-shaped placement grooves are formed at the four corners of the top surface of the lower die base, and a lever is fitted inside each groove. The two sides of the middle portion of the lever are movably connected to the inner walls of the two sides of the placement groove. A moving plate is fitted inside the placement groove. The device can be moved manually using the moving mechanism, reducing the labor intensity of workers. Furthermore, the moving mechanism allows for more accurate positioning, avoiding the need for manual movement where partial force causes the upper and lower dies to be in an off-center position, requiring gradual adjustment.

[0004] Existing brake pad backplate blank stamping equipment lacks a precise sheet metal pre-positioning structure, making it prone to warping and misalignment during sheet metal conveying. This results in substandard contour and hole accuracy of the stamped backplate blank, leading to a high defect rate. After stamping, scrap material tends to stick to the mold surface, requiring manual removal. This not only reduces production efficiency but also poses safety hazards due to manual operation and can cause blockages in the scrap discharge channel. To address these issues in existing technology, there is an urgent need to develop a brake pad backplate blank stamping equipment with precise positioning and automatic material discharge and ejection capabilities. This would improve the stamping accuracy and production efficiency of the backplate blank, while reducing production safety hazards and equipment maintenance costs. Summary of the Invention

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0024] As shown in Figures 1-9, a brake pad backplate blank stamping equipment includes a stamping machine 1 and a feeding platform 2. The feeding platform 2 is located at the feed inlet of the stamping machine 1. The equipment also includes: a die unloading platform 3, a flattening assembly 4, a punch mechanism 5, a die assembly 6, an ejection assembly 7, a control assembly 8, and a discharge mechanism 9. The die unloading platform 3 is fixedly located at the lower end of the inner side of the stamping machine 1 housing. The flattening assembly 4 is located around the die unloading platform 3 for positioning the sheet metal. The punch mechanism 5 includes a preview assembly 51 and a punch assembly 52. ​​The preview assembly 51 is rotatably mounted on... The stamping machine 1 uses a light beam to pre-position the stamping position of the sheet metal inside the stamping moving parts. The punch assembly 52 is located at the bottom of the stamping moving parts of the stamping machine 1 and is detachable and replaceable. The mold assembly 6 is located inside the mold unloading platform 3 and is slidably connected to the inner wall of the mold unloading platform 3. The discharge mechanism 9 is located inside the mold assembly 6 and is used to intercept and discharge waste material. The ejection assembly 7 is used to push the formed back plate blank out of the mold unloading platform 3. The control assembly 8 is located outside the stamping machine 1 and controls the connection of each component.

[0025] The mold unloading platform 3 serves as the core load-bearing foundation of the equipment. Its square frame structure ensures the installation and sliding space of the mold component 6, and provides a smooth channel for the falling of waste material and the discharge of blanks. The holes at its lower end are precisely aligned with the waste holes of the mold block 61, ensuring that the waste material falls directly for collection. The discharge port 31 on the side is set opposite to the unloading component 7, so that the pushing and discharge of the formed blanks is unobstructed, improving the unloading efficiency.

[0026] In an optional embodiment, the mold assembly 6 includes a model block 61, a positioning platform 62, and a slow-lifting mechanism 63. The end face of the model block 61 is a back plate model, and a waste hole is provided in the center. The model block 61 is slidably connected to the inner wall of the mold unloading platform 3. The positioning platform 62 is sleeved on the outside of the model block 61 and is slidably connected to the outer wall of the model block 61. The positioning platform 62 is fixedly connected to the mold unloading platform 3. A pad block 621 is provided on the upper surface of the positioning platform 62. The slow-lifting mechanism 63 is used to support the model block 61.

[0027] In this embodiment, the end face contour of the model block 61 is precisely matched with the forming size of the brake pad back plate blank. It is the core mold component for sheet metal stamping. It can slide up and down along the inner wall of the mold blanking table 3 and cooperate with the punch mechanism 5 to complete the stamping action. The positioning table 62 provides radial positioning for the model block 61 to prevent the model block 61 from shifting during the sliding process and to ensure stamping accuracy. The pad block 621 on it cooperates with the convex key of the push block 91 to realize the position limitation of the push block 91, which provides a basis for the normal operation of the material discharge mechanism 9. Moreover, through the combination of the pad block 621 and the convex key of the push block 91, the positioning table 62 can support and fix the model block 61, preventing the model block 61 from falling down during punching and causing the stamping action to be chaotic.

[0028] In an optional embodiment, the gradual lifting mechanism 63 includes a side ear 631, a support spring 632, and a damping lifting rod 633. The side ear 631 is fixedly disposed on the outer surface of the model block 61. The damping lifting rod 633 has a damping effect when it extends. The upper end of the damping lifting rod 633 is fixedly connected to the side ear 631. The support spring 632 is disposed on the outside of the damping lifting rod 633 and has the function of supporting the side ear 631.

[0029] In this embodiment, the side lug 631 provides support for the connection between the gradual lifting mechanism 63 and the mold block 61. During stamping, the mold block 61 slides downward under the pressure of the punch mechanism 5, causing the side lug 631 to compress the support spring 632 and the damping lifting rod 633, so that the support spring 632 stores elastic potential energy. After stamping is completed, the elastic potential energy of the support spring 632 is released, pushing the side lug 631 to drive the mold block 61 to rise. The damping lifting rod 633 plays a damping buffering role on the upward movement of the mold block 61, avoiding the impact caused by the instantaneous reset of the spring force of the mold block 61, reducing the wear of the mold block 61 with the positioning table 62 and the mold unloading table 3, extending the service life of the mold, and providing pushing time for the discharge of the back plate blank after molding, avoiding the problem of the mold block 61 carrying the back plate rising instantly and affecting the next stamping.

[0030] In an optional embodiment, the discharge mechanism 9 includes a pushing block 91 and a reset elastic band 92. The pushing block 91 is slidably connected to the inside of the model block 61 and extends through the waste hole of the model block 61. The upper end of the pushing block 91 is provided with a chamfer and a recessed platform 911. The upper surfaces of the two symmetrically distributed pushing blocks 91 are at different heights. One end of the reset elastic band 92 is connected to the model block 61 and the other end is connected to the pushing block 91, and is used to pull the pushing block 91 to reset.

[0031] In this embodiment, the chamfer at the upper end of the pushing block 91 facilitates the punching post 522 to push the pushing block 91 to slide to both sides after punching, and at the same time, it prevents the waste from getting stuck between the pushing block 91 and the waste hole when the waste slides down the inclined surface; the two sets of pushing blocks 91 have different upper surface heights, so that the falling waste will flip after contact and fall smoothly through the gap between the pushing blocks 91, realizing the rapid discharge of waste; the recessed platform 911 provides space for the punching post 522 to fall and be accommodated and engaged. The punching column 522 can push the push block 91 to slide to both sides, and then the sinking platform 911 can be used to push the push block 91 to descend. After the push block 91 is misaligned with the pad block 621, the push block 91 continues to push the model block 61 to descend, providing space for the subsequent stamping of the back plate. The reset elastic band 92 is made of highly elastic rubber. After the push block 91 is slid by external force, it can quickly reset the push block 91 by its own elasticity, ensuring the cyclic use of the discharge mechanism 9.

[0032] In an optional embodiment, the lower surface of the push block 91 is provided with a protruding key, which contacts the pad block 621.

[0033] In this embodiment, when the protruding key of the pushing block 91 is precisely engaged with the pad block 621 of the positioning table 62, the position of the pushing block 91 is limited, which can effectively intercept the pressure generated during punching that causes the model block 61 to descend; when the punching column 522 pushes the pushing block 91 to slide to both sides, the protruding key and the pad block 621 are misaligned, and the sliding of the pushing block 91 is unrestricted. The punching column 522 pushes the pushing block 91 and causes the model block 61 to slide downward. The cooperation between the protruding key and the pad block 621 realizes the linkage control between the position of the pushing block 91 and the movement of the model block 61. The structure is ingeniously designed and requires no additional driving components.

[0034] In an optional embodiment, the mold unloading platform 3 is generally in the shape of a directional frame, the model block 61 penetrates through the upper surface of the mold unloading platform 3, the lower end of the mold unloading platform 3 is provided with a hole that communicates with the waste hole of the model block 61, the side of the mold unloading platform 3 is provided with a discharge port 31, and the unloading component 7 is provided on the inner side of the mold unloading platform 3 away from the discharge port 31.

[0035] In this embodiment, the square frame structure of the mold unloading platform 3 is made of high-strength alloy material, which has good structural strength and rigidity and can withstand the huge pressure during the stamping process. The size of the hole at the lower end is slightly larger than the waste hole of the mold block 61 to ensure that the waste falls smoothly into the waste collection box below. The edge of the discharge port 31 on the side is chamfered and ground to prevent the formed blank from being scratched during the discharge process and to ensure the surface quality of the product.

[0036] In an optional embodiment, the punch assembly 52 includes a punch block 521, a punching post 522, and a pressing block 523. The punch block 521 is connected to the punching machine 1 by screws. The punching post 522 is provided on the surface of the punch block 521. The position of the punching post 522 corresponds to the scrap hole on the surface of the mold block 61. Pressing blocks 523 are connected to both sides of the punch block 521. The pressing blocks 523 are connected to the punch block 521 by springs. A guide rod is provided at the center of the spring. The pressing blocks 523 are used to form a back plate shape with the punch block 521.

[0037] In this embodiment, the punch block 521 is detachably connected to the stamping machine 1 with screws, which facilitates the replacement of the punch assembly 52 according to the production needs of back plate blanks of different specifications, thus improving the equipment versatility; the punching column 522 and the scrap hole position of the mold block 61 are precisely aligned to ensure the accuracy of the punching position; the pressing block 523 contacts the plate before the punch block 521 during the stamping process, pre-pressing and fixing the plate to prevent the plate from shifting during the stamping process; the cooperation of the spring and the guide rod determines the movement trajectory of the pressing block 523, preventing the pressing block 523 from conflicting with the punch block 521; at the same time, the pressing block 523 and the punch block 521 form a whole back plate shape during the stamping process, ensuring the contour accuracy of the back plate blank.

[0038] In an optional embodiment, the flattening assembly 4 consists of two sets of rollers and two sets of pressing shafts. The two sets of rollers are respectively arranged on the front and rear sides of the die unloading table 3 for transporting the stamped sheet metal. The two sets of pressing shafts are connected to the stamping machine 1 by screws and are arranged on both sides above the sheet metal.

[0039] In this embodiment, the flattening component 4 can adjust the conveying speed through the control component 8 to keep it synchronized with the conveying speed of the material conveying platform 2, thereby achieving stable conveying of the sheet material. The contact pressure between the pressing shaft and the sheet material can be adjusted by adjusting the tightness of the screw, which can both flatten and limit the sheet material without scratching the surface of the sheet material. The two sets of pressing shafts are placed above the sheet material to flatten it from both sides, effectively solving the problem of warping and offset of the sheet material during the conveying process and ensuring the flatness of the sheet material on the mold component 6.

[0040] In an optional embodiment, the unloading assembly 7 is an electric telescopic rod with a push plate at the free end, and the telescopic rod has the function of quickly extending and retracting.

[0041] In this embodiment, the electric telescopic rod of the ejector assembly 7 adopts a servo electric cylinder, which has high operating accuracy and adjustable extension speed. The push plate at its free end is made of soft rubber material. The contour of the push plate matches the edge of the back plate blank, so that it can fit tightly against the surface of the blank when pushing the blank, preventing the blank from sliding or falling during the pushing process. The rapid extension and retraction function of the telescopic rod allows the formed blank to be quickly pushed out of the mold unloading table 3 after stamping, improving the unloading efficiency and freeing up space for the next stamping operation, ensuring the continuity of production.

[0042] In use, first, according to the specifications of the brake pad backplate blank to be produced, replace the appropriate punch assembly 52, and fix the punch block 521 to the stamping machine 1 with screws. Adjust the rotation angle of the preview assembly 51 so that the laser positioning instrument projects a laser positioning line that matches the stamping contour of the backplate blank. Then, place the cut and flattened steel plate on the feeding platform 2, and transport the plate to the bottom of the punch mechanism 5 through the feeding platform 2. During the conveying process, the plate is flattened by the roller conveyor of the flattening assembly 4 and pressed by the pressing shaft, and is stably placed on the upper surface of the mold assembly 6. The operator fine-tunes the position of the plate according to the laser positioning line to complete the precise positioning. During stamping, the control assembly 8 controls the stamping moving parts of the stamping machine 1 to move downward. In motion, the punch mechanism 5 descends synchronously, with the punching column 522 descending first to contact and punch the sheet metal. The falling scrap material flips upon contact with two sets of push blocks 91 of unequal heights, falling through the gap between the push blocks 91 into the scrap collection box below the die unloading platform 3. After punching, the punching column 522 continues to descend, its bottom end entering the sinking platform 911 of the push block 91 and pushing the push block 91 to slide to both sides, causing the protruding key on the lower surface of the push block 91 to misalign with the pad block 621 of the positioning platform 62. The punching column 522 continues to push the push block 91 to follow its descent, and the push block 91 drives the mold block 61 to slide downward along the inner wall of the die unloading platform 3, compressing the slow-lifting mechanism 63. The support spring 632 and the damping lifting rod 633 retract; after the punch mechanism 5 continues to descend, the punch block 521 and the pressing block 523 jointly contact the plate, performing a secondary punching on the plate, so that the plate is punched and formed according to the end face contour of the mold block 61. The punched back plate blank falls into the frame of the mold unloading table 3; after the punching is completed, the control component 8 controls the punching motion parts of the punching machine 1 to move upward and reset, the punch block 521 and the punching column 522 rise synchronously, and the pressing block 523 is pressed against the surface of the formed back plate blank by the elastic force of the spring, preventing the blank from rising with the punch mechanism 5; at the same time, the control component 8 controls the electric telescopic rod of the unloading component 7 to extend quickly, and the telescopic rod pushes The push plate moves towards the discharge port 31, pushing the formed back plate blank out of the discharge port 31 and onto the mold unloading table 3, where it falls into the finished product collection box below. After the unloading is completed, the electric telescopic rod quickly retracts and resets. After the punch mechanism 5 is fully reset, the support spring 632 of the slow lifting mechanism 63 releases its elastic potential energy, pushing the side ear 631 to drive the model block 61 to rise slowly. The damping lifting rod 633 dampens and buffers the upward movement of the model block 61. At the same time, the reset elastic band 92 of the discharge mechanism 9 pulls the push block 91 to slide and reset towards the center, so that the protruding key at the lower end of the push block 91 is precisely engaged with the pad block 621 of the positioning table 62. The equipment returns to its initial state and waits for the next punching and stamping operation.
