Description

Technical Field

[0001] This utility model belongs to the field of workpiece stamping technology, specifically a multi-station integrated stamping die for a brake disc dust cover. Background Technology

[0002] Brake disc dust covers are an important component of automotive braking systems. They are mainly used to protect the brake discs and related components from external impurities such as dust, mud, and water stains, ensuring the normal operation of the braking system and extending its service life.

[0003] Stamping is a key step in the production of brake disc dust covers. It enables efficient and high-precision production of brake disc dust covers. When stamping brake disc dust covers, the workpiece to be stamped is placed on the lower die, and then the upper die is pressed down by the drive mechanism, so that the workpiece is formed under the extrusion of the two dies. However, after stamping, the workpiece may become stuck in the die groove due to various factors, making it difficult to remove. At the same time, most existing impact dies are single-station dies. When the upper die is pressed down by the drive mechanism to extrude the workpiece, other operations cannot be performed at the same time, resulting in low work efficiency.

[0004] Therefore, this utility model provides a multi-station integrated stamping die for a brake disc dust cover. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A multi-station integrated stamping die for a brake disc dust cover, comprising a lower die and multiple upper dies; the top of the lower die has multiple die slots; the number of upper dies is the same as the number of die slots; multiple sliding grooves are opened in the middle of the lower die; a first push rod is slidably connected to the middle of the sliding groove; a pair of guide rods are installed at the bottom of the lower die; a support frame is slidably connected to the middle of the pair of guide rods; multiple second push rods are fixedly connected to the top of the support frame; a first connecting plate is fixedly connected to the bottom of the side wall of the upper die; second connecting plates are fixedly connected to the top of both ends of the support frame; the second connecting plates have a certain elasticity; hooks are provided at the bottom of the side wall of the first connecting plate and the top of the side wall of the second connecting plate; Through the above structure, while stamping is being performed at some stations, workpieces at other stations can be picked up and adjusted, improving work efficiency. Simultaneously, after stamping is completed, the workpiece can automatically detach from the die slot, reducing the inconvenience of removing workpieces due to overly tight fit.

[0007] Preferably, a limiting block is fixedly connected to the side wall of the lower mold; a fixing frame is fixedly connected to the side wall of the lower mold; a bearing frame is rotatably connected to the middle of the fixing frame; a fixing block is fixedly connected to the side wall of the second connecting plate; the side wall of the limiting block and the top of the fixing block are both inclined; with the above structure, after the workpiece is ejected from the mold groove, the second connecting plate and the first connecting plate can be automatically separated, and the bearing frame can be automatically supported so that the workpiece can always be in a lifted state, while the upper mold can rise to a higher height, making the space for removing the workpiece more spacious and improving the convenience of operation.

[0008] Preferably, a magnet is fixed to the side wall of the second connecting plate; the support frame is made of magnetic material; through the above structure, an attractive force can be generated at the bottom of the support frame, so that the bottom of the support frame can move quickly under the fixed block under the influence of the attractive force, thereby stably supporting the fixed block when the second connecting plate descends, and improving the applicability of the device.

[0009] Preferably, the bottom of the fixing block is provided with a slot; the slot is located above the end of the magnet; with the above structure, when the fixing block is supported by the support frame, the bottom of the support frame is embedded in the slot and is difficult to detach, reducing the occurrence of the support frame falling due to the separation of the support frame and the fixing block.

[0010] Preferably, a wear-resistant sheet is bonded to the top of the side wall of the fixing block; the wear-resistant sheet is made of a smooth and wear-resistant material; through the above structure, the friction between the second connecting plate, the limiting block and the first connecting plate can be reduced, thereby reducing the wear of the components. When the wear-resistant sheet is worn to a certain extent, it can be easily separated and replaced.

[0011] Preferably, the bottom of the lower mold is provided with a pair of threaded grooves; the top end of the guide rod is threaded into the inside of the threaded grooves; with the above structure, when the mold is not installed and used, the guide rod can be separated from the lower mold, thereby making the bottom of the lower mold flat, which is convenient for storing the lower mold and reduces the inconvenience caused by the support frame and other components at the bottom of the lower mold for storage.

[0012] Preferably, the slide groove has multiple grooves in the middle; the multiple grooves are evenly distributed in the middle of the slide groove; through the above structure, the air inside the slide groove can circulate freely through the grooves, reducing the situation where some air is difficult to escape when the components are tightly fitted, resulting in high pressure that hinders the sliding of the first push rod. On the other hand, this setting can make the first push rod fit more closely with the top of the slide groove through the manufacturing process, reducing the gap between the slide groove and the first push rod, thereby reducing the impact of a large gap on the stamping quality of the product.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The multi-station integrated stamping die for brake disc dust cover described in this utility model, through the arrangement of lower die, die groove, upper die, slide groove, first ejector rod, guide rod, bearing frame, second ejector rod, first connecting plate, and second connecting plate, allows for the handling and adjustment of workpieces at other stations while stamping is being performed at some stations, thereby improving work efficiency. At the same time, after stamping is completed, the workpiece can be automatically detached from the die groove, reducing the occurrence of workpieces being too tightly fitted, which would make removal inconvenient.

[0015] 2. The multi-station integrated stamping die for brake disc dust cover described in this utility model, through the setting of limiting blocks, fixing frames, bearing frames, and fixing blocks, can automatically separate the second connecting plate and the first connecting plate after the workpiece is ejected from the mold groove, and automatically support the bearing frame so that the workpiece can always be in a lifted state, while the upper die can rise to a higher height, making the space for removing the workpiece more spacious and improving the convenience of operation.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4As shown in the figure, a multi-station integrated stamping die for a brake disc dust cover according to an embodiment of the present invention includes a lower die 1 and multiple upper dies 13; the top of the lower die 1 has multiple die slots 12; the number of upper dies 13 is the same as the number of die slots 12; multiple sliding grooves 14 are opened in the middle of the lower die 1; a first push rod 15 is slidably connected to the middle of the sliding groove 14; a pair of guide rods 16 are installed at the bottom of the lower die 1; a support frame 17 is slidably connected to the middle of the pair of guide rods 16; multiple second push rods 18 are fixedly connected to the top of the support frame 17; the upper dies 13... A first connecting plate 19 is fixedly connected to the bottom of the side wall of the support frame 17; a second connecting plate 110 is fixedly connected to the top of both ends of the support frame 17; the second connecting plate 110 has a certain elasticity; hooks are provided at the bottom of the side wall of the first connecting plate 19 and the top of the side wall of the second connecting plate 110; during operation, multiple workpieces to be stamped are placed on different mold slots 12, and then the upper mold 13 is driven down by the drive mechanism to stamp the workpieces on the mold slots 12. After the upper mold 13 is lowered to the lowest point, the hooks at the bottom of the first connecting plate 19 will engage with the second connecting plate 110. The top hooks are staggered. After stamping, the upper mold 13 rises and separates from the lower mold 1 as the drive mechanism operates. At this time, the first connecting plate 19 drives the second connecting plate 110 to rise synchronously through the hooks, thereby driving the support frame 17 and the second ejector rod 18 to rise. The rising second ejector rod 18 inserts into the slide groove 14 and pushes the first ejector rod 15 to rise, thereby lifting the workpiece that has been stamped and embedded in the mold groove 12. When it is necessary to lower the support frame 17, the second connecting plate 110 can be pressed to bend the second connecting plate 110 and connect it to the first ejector rod 15. The connecting plate 19 separates, allowing the support frame 17 and the second push rod 18 to descend. Since the multiple mold slots 12 and the upper mold 13 are set in pairs, while stamping one workpiece, operations such as placing the workpiece and taking out the finished product can be performed at another station. With the above structure, while stamping is being performed at some stations, workpieces at other stations can be picked up and adjusted, improving work efficiency. At the same time, after stamping is completed, the workpiece can automatically detach from the inside of the mold slot 12, reducing the situation where the workpiece is too tightly fitted, which would make it inconvenient to take it out.

[0024] like Figures 1 to 4As shown, a limiting block 2 is fixedly connected to the side wall of the lower mold 1; a fixing frame 21 is fixedly connected to the side wall of the lower mold 1; a bearing frame 22 is rotatably connected to the middle of the fixing frame 21; a fixing block 23 is fixedly connected to the side wall of the second connecting plate 110; the side wall of the limiting block 2 and the top of the fixing block 23 are both inclined. During operation, due to the limited length of the first connecting plate 19, if the first connecting plate 19 is not separated from the second connecting plate 110 after the second connecting plate 110 is raised to its highest position, the first connecting plate 19 and the upper mold 13 will have difficulty continuing to rise, otherwise it will damage the components. Therefore, the gap between the upper mold 13 and the lower mold 1 is limited, which will have a certain impact on the removal of the workpiece. Through the setting of the limiting block 2 and the bearing frame 22, during the rising process of the second connecting plate 110, the bottom of the bearing frame 22 will first contact the top of the fixing block 23 and be pushed by the inclined top of the fixing block 23. The support frame 22 is rotated, and then the second connecting plate 110 continues to rise, causing the fixing block 23 to enter the support frame 22. Then, the top of the second connecting plate 110 will contact the inclined surface of the limiting block 2, causing the top of the second connecting plate 110 to be blocked from moving, thereby separating the second connecting plate 110 from the first connecting plate 19. Then the second connecting plate 110 will fall, but at this time the support frame 22 will lift the fixing block 23, making it difficult for the support frame 17 to continue falling. Then the upper mold 13 and the first connecting plate 19 can rise to a higher height. With the above structure, after the workpiece is ejected from the mold groove 12, the second connecting plate 110 and the first connecting plate 19 can be automatically separated, and the support frame 17 can be automatically supported so that the workpiece can always be in the lifted state. The upper mold 13 can rise to a higher height, making the space for removing the workpiece more spacious and improving the convenience of operation.

[0025] like Figures 3 to 4 As shown, a magnet 3 is fixed to the side wall of the second connecting plate 110; the support frame 22 is made of magnetic material; during operation, when the upper mold 13 rises too quickly, the bottom end of the support frame 22 is easily pushed away from the fixed block 23 by the rapidly rising fixed block 23, and does not return to below the fixed block 23 when the first connecting plate 19 and the second connecting plate 110 separate and the second connecting plate 110 falls, making it difficult for the support frame 22 to lift the fixed block 23. However, by setting the magnet 3, a magnetic force can be generated on the bottom end of the support frame 22, so that the bottom end of the support frame 22 can move quickly to below the fixed block 23 under the influence of the magnetic force, thereby stably supporting the fixed block 23 when the second connecting plate 110 descends, improving the applicability of the device.

[0026] like Figure 4As shown, a slot 4 is provided at the bottom of the fixing block 23; the slot 4 is located above the end of the magnet 3; during operation, when the fixing block 23 is supported by the support frame 22, the vibration generated by the operation of the equipment may be transmitted to the support frame 22 and the fixing block 23, causing the support frame 22 to be affected and gradually shift in position from the fixing block 23. Therefore, the support frame 22 may be affected and separate from the fixing block 23, causing the support frame 17 to fall. By setting the slot 4, when the fixing block 23 is supported by the support frame 22, the bottom of the support frame 22 can be inserted into the slot 4 and is difficult to detach, reducing the occurrence of the support frame 17 falling due to the separation of the support frame 22 and the fixing block 23.

[0027] like Figure 4 As shown, a wear-resistant sheet 5 is bonded to the top of the side wall of the fixing block 23; the wear-resistant sheet 5 is made of smooth and wear-resistant material; by setting the wear-resistant sheet 5, the friction between the second connecting plate 110, the limiting block 2, and the first connecting plate 19 can be reduced, thereby reducing the wear of the components. When the wear-resistant sheet 5 is worn to a certain extent, it can be easily separated and replaced.

[0028] like Figure 3 As shown, a pair of threaded grooves 6 are provided at the bottom of the lower mold 1; the top end of the guide rod 16 is threaded into the inside of the threaded groove 6; during operation, when the mold is not installed and used, the guide rod 16 can be separated from the lower mold 1, thereby making the bottom of the lower mold 1 flat, which is convenient for storing the lower mold 1 and reduces the inconvenience caused to the storage of the lower mold 1 by components such as the support frame 17 at the bottom of the lower mold 1.

[0029] like Figure 3 As shown, multiple grooves 7 are provided in the middle of the slide groove 14; the multiple grooves 7 are evenly distributed in the middle of the slide groove 14; through the above structure, the air inside the slide groove 14 can circulate freely through the grooves 7, reducing the situation where some air is difficult to escape when the components are tightly fitted, resulting in high pressure that hinders the sliding of the first push rod 15. On the other hand, this arrangement can make the first push rod 15 fit more closely with the top of the slide groove 14 through the manufacturing process, reducing the gap between the slide groove 14 and the first push rod 15, thereby reducing the impact of a large gap on the stamping quality of the product.

[0030] During operation, multiple workpieces requiring stamping are placed on different die slots 12. The upper die 13 is then lowered via a drive mechanism to stamp the workpieces on the die slots 12. After the upper die 13 reaches its lowest point, the hooks at the bottom of the first connecting plate 19 interlock with the hooks at the top of the second connecting plate 110. After stamping is complete, the upper die 13 rises with the operation of the drive mechanism, separating from the lower die 1. At this time, the first connecting plate 19 drives the second connecting plate 110 to rise synchronously via the hooks, thereby causing the support frame 17 and the second ejector rod 18 to rise. The rising second ejector rod 18 inserts into the slide groove 14 and pushes the first ejector rod 15 upward, thus embedding the workpiece into the die slot. The workpiece, after being stamped within 12 minutes, is lifted. When it is necessary to lower the support frame 17, the second connecting plate 110 can be pressed to bend it and separate it from the first connecting plate 19, thereby allowing the support frame 17 and the second ejector rod 18 to descend. Since the multiple die slots 12 and the upper die 13 are set in pairs, while stamping one workpiece, operations such as placing the workpiece and removing the finished product can be performed at another station. Due to the limited length of the first connecting plate 19, if the first connecting plate 19 is not separated from the second connecting plate 110 after the second connecting plate 110 has risen to its highest point, the first connecting plate 19 and the upper die 13 will be difficult to continue rising, otherwise it will damage the component. Damage to the upper mold 13 and lower mold 1 results in a limited gap, which affects the removal of the workpiece. Through the setting of the limiting block 2 and the bearing frame 22, during the rising process of the second connecting plate 110, the bottom of the bearing frame 22 first contacts the top of the fixing block 23 and is pushed by the inclined top of the fixing block 23, causing the bearing frame 22 to rotate. Then, the second connecting plate 110 continues to rise, causing the fixing block 23 to enter the bearing frame 22. Next, the top of the second connecting plate 110 contacts the inclined surface of the limiting block 2, obstructing the movement of the top of the second connecting plate 110, thereby separating the second connecting plate 110 from the first connecting plate 19. Subsequently, the second connecting plate 110 will fall. However, at this time, the support frame 22 will lift the fixing block 23, making it difficult for the support frame 17 to continue falling. Then the upper mold 13 and the first connecting plate 19 can rise to a higher height. With the setting of the magnet 3, the bottom of the support frame 22 can be attracted, so that the bottom of the support frame 22 can be quickly moved under the fixing block 23 due to the attraction. With the setting of the slot 4, when the fixing block 23 is supported by the support frame 22, the bottom of the support frame 22 will be stuck in the slot 4 and difficult to get out. When the mold is not installed and used, the guide rod 16 can be separated from the lower mold 1, so that the bottom of the lower mold 1 becomes flat and it is easy to store the lower mold 1.
