Technical Field
[0001] This application relates to the field of punching die technology, and in particular, to a punching die for automotive parts. Background Art
[0002] Automotive roof pillars are structural components that enhance the strength and stiffness of the vehicle body. Their main function is to resist impact forces during vehicle rollover or overturning, protecting the safety of drivers and passengers. Automotive roof pillars, also known as A-pillars, B-pillars, C-pillars, or D-pillars, are important components in the automotive body structure. These pillars connect the roof and the body, strengthening the strength and stiffness of the body.
[0003] During the actual production of automotive parts, it is often necessary to perform punching operations on automotive roof pillars with a certain shape so that they can be fitted and installed with other automotive components. For factories engaged in large-scale production or processing of automotive parts, improving the equipment for punching automotive roof pillars can greatly improve work efficiency and thus increase production. Utility Model Content
[0004] In order to improve the structure of the punching die for automotive roof pillars, while reducing the production cost of the die and making it more convenient to operate, thereby improving its work efficiency, this application provides a punching die for automotive parts.
[0005] The punching die for automotive parts provided by this application adopts the following technical solutions:
[0006] A punching die for automotive parts, used for punching the notch of a mud trough plate, includes a base, two support plates symmetrically arranged on both sides of the base, a mounting plate installed at the top ends of the two support plates, and two punching mechanisms symmetrically arranged at the upper end of the base. The punching mechanism includes a backing plate fixedly installed on the base and a cover plate installed on the top of the backing plate. A limiting groove is jointly formed on the side where the backing plate and the cover plate are close to each other. The mud trough plate is slidably arranged in the limiting groove. A punching block slidably penetrates through the top end of the cover plate. A punching head is fixedly installed at the lower end of the punching block. A discharge hole for discharging waste and slidably matched with the punching block is penetrated through the backing plate. A driving mechanism for driving the punching block to perform punching is arranged at the top end of the cover plate, and a pushing mechanism for pushing the mud trough plate out of the limiting groove is arranged on the base.
[0007] By adopting the above technical solution, the mud chute plate is clamped between the cover plate and the backing plate and is in sliding fit with the limiting groove along the length direction, which can not only ensure the accuracy during the punching of the mud chute plate, but also facilitate the quick feeding of the mud chute plate by the feeding mechanism after the punching operation, improving the working efficiency and accuracy of the equipment. At the same time, since the limiting groove matches the shape of the mud chute plate, the mud chute plate will not be bent due to uneven force during the punching process, improving the pass rate of the finished product.
[0008] Optionally, two first sliding grooves are symmetrically formed on one side of the two support plates close to each other, and both sides of the mounting plate are respectively slidably connected in the two first sliding grooves.
[0009] By adopting the above technical solution, the quick disassembly of the mounting plate can be realized, so as to facilitate the replacement of the parts of the driving mechanism, enabling the equipment to be adapted according to different part processing requirements and improving the operation flexibility of the equipment.
[0010] Optionally, the driving structure includes a plurality of support columns fixedly installed on the cover plate and a cylinder installed on the mounting plate. The telescopic rod of the cylinder penetrates through the mounting plate and is connected with a pressing plate. One end of the punching block far from the cover plate is fixedly connected to one side of the pressing plate far from the cylinder, and the pressing plate is slidably connected with all the support columns.
[0011] By adopting the above technical solution, when punching the mud chute plate is required, the cylinder located on the mounting plate drives the pressing plate to slide along the axis direction of the support column, and then the pressing plate squeezes the punching block located at its bottom, enabling the punching head to perform punching operation on the mud chute plate. The structure is simple, and it can avoid uneven force on the contact area of the punching block when being squeezed during the punching process, improving the structural stability of the equipment during operation.
[0012] Optionally, a limiting component for restricting the pressing plate from detaching from the plurality of support columns is arranged on the support column, including a limiting block arranged at one end of the plurality of support columns far from the cover plate. A second sliding groove with a T-shaped cross-section is formed through the middle of the limiting block, and the second sliding groove communicates with both ends of the limiting block along the vertical direction. A docking head is fixedly installed at the end of the telescopic rod of the cylinder, and the docking head is slidably arranged in the second sliding groove. One end of the docking head far from the cylinder is fixedly connected with the pressing plate.
[0013] By adopting the above technical solution, the second sliding groove can restrict the movement of the docking head along the punching direction, thus realizing the prevention of the pressing plate fixedly connected with the docking head from detaching from the support column while not affecting the sliding of the mounting plate and the cylinder fixedly arranged on the mounting plate. The structure is simple and easy to operate.
[0014] Optionally, a plurality of rubber stoppers for preventing the pressing plate from colliding with the support plate are provided on the cover plate. The rubber stoppers are in a conical structure, and the end with a larger cross-sectional dimension of the rubber stopper is fixedly connected to the upper end of the cover plate.
[0015] By adopting the above technical solution, the rubber stoppers can provide buffering for the pressing plate, avoiding the collision between the pressing plate and the cover plate during the punching process, which may cause damage to the equipment parts, and improving the stability and safety during the operation of the mold.
[0016] Optionally, the pushing mechanism includes a column fixedly installed on one side of the base plate along the length direction. A square hole is provided in the column along the length direction of the base plate. A pushing rod is slidably inserted into the square hole. One end of the pushing rod extends into the limiting groove and abuts against one end of the mud groove plate.
[0017] By adopting the above technical solution, the punched mud groove plate can be pushed outside the limiting groove, saving the overall manufacturing cost of the mold and improving the overall economic value of the mold.
[0018] Optionally, a receiving block is fixedly installed at one end of the base plate away from the column. A receiving groove flush with the limiting groove is provided at the upper end of the receiving block. The mud groove plate is movably placed in the receiving groove. Two positioning blocks are symmetrically installed on both sides of the receiving groove on the receiving block, and the two positioning blocks jointly clamp and position the mud groove plate.
[0019] By adopting the above technical solution, the pushing rod pushes the punched mud groove plate into the receiving block. Since the limiting groove is flush with the receiving groove, it can be ensured that the mud groove plate does not shake during the pushing process. At the same time, the two positioning blocks on the receiving block mainly play a limiting role on the mud groove plate.
[0020] Optionally, a plurality of positioning holes are symmetrically provided on both sides of the receiving groove on the receiving block. A waist-shaped hole is provided through the positioning block along the width direction of the receiving groove. A positioning bolt for fixing the positioning block is jointly inserted into the waist-shaped hole and the positioning hole.
[0021] By adopting the above technical solution, the distance between the two sides of the two positioning blocks close to each other can be adjusted, so that it can always play a limiting role on the mud groove plate and improve the adjustability of the mold.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. The present application can quickly punch the mud groove plate, thereby improving the working efficiency and finished product quality of the mold for punching the mud groove plate;
[0024] 2. The present application provides that the backing plate and the cover plate jointly form a limiting groove that matches the shape of the mud trough plate, which can ensure that the mud trough plate will not shake or bend during the processing, and improve the accuracy of the punching operation.
[0025] 3. In the present application, the mounting plate and the cylinder are installed in a sliding connection manner, so that the mold driving part can be easily disassembled, facilitating the installation and maintenance of the mold structure. Brief Description of the Drawings

Detailed Description of the Embodiment
[0033] The following is a further detailed description of the present application with reference to the Figures 1-6 drawings.
[0034] The embodiment of the present application discloses a punching die for automobile parts.
[0035] Refer to Figure 1, An automotive part punching die is used for punching the notch of the mud trough plate 1 on the automotive roof pillar to improve the working efficiency and quality of the punching process. The die body of this application specifically includes a base 2 arranged at the bottom, two support plates 3 symmetrically and fixedly arranged on opposite sides of the base 2, a mounting plate 4 connected to the two support plates 3 on both sides respectively, and two punching mechanisms 5 symmetrically arranged side by side inside the frame structure jointly formed by the base 2, the two support plates 3, and the mounting plate 4. Among them, the two support plates 3 are perpendicular to the base 2, and first sliding grooves 31 are respectively penetrated along the length direction on the inner sides of the two support plates 3 close to each other. The two sides of the mounting plate 4 are respectively slidably fitted inside the two first sliding grooves 31 to facilitate the quick installation and disassembly of the mounting plate 4.
[0036] Referring to Figure 2 , Specifically, the punching mechanism 5 includes a backing plate 51 fixedly installed on the base 2 and a cover plate 52 detachably arranged on the side of the backing plate 51 away from the base 2. Openings are respectively penetrated along the length direction on the sides of the cover plate 52 and the backing plate 51 close to each other, and the two openings on the cover plate 52 and the backing plate 51 jointly enclose a limiting groove 53. The mud trough plate 1 is slidably fitted in the limiting groove 53 to limit the mud trough plate 1 and prevent the mud trough plate 1 from shaking during punching, resulting in the deviation of the punching position.
[0037] Referring to Figure 2 and Figure 3 , Further, four support columns 54 are arranged near the corner positions on the side of the cover plate 52 away from the backing plate 51, and a pressing plate 55 is slidably sleeved on the four support columns 54 together. A cylinder 41 is arranged on the mounting plate 4, and the telescopic rod of the cylinder 41 penetrates the mounting plate 4 and its end is fixedly connected to the pressing plate 55 to drive the pressing plate 55 to slide along the axis direction of the support column 54. One end of the pressing plate 55 away from the cylinder 41 is fixedly connected with a punching block 56 that movably penetrates the cover plate 52, and a punching head 57 for punching and forming the mud trough plate 1 is detachably arranged at one end of the punching block 56 away from the pressing plate 55.
[0038] What is shown in the embodiment of this application is a structure of the punching mechanism 5, and the punching mechanism 5 in other prior arts applicable to this application can also provide technical support for the punching mechanism 5 in the claims of this application.
[0039] Preferably, a discharge hole 511 for discharging punching waste is penetrated on the backing plate 51, the discharge hole 511 penetrates the base 2, and the punching block 56 is movably fitted inside the discharge hole 511, so that during punching, the punching head 57 will not collide with the backing plate 51 and the base 2, improving the safety of the die during operation.
[0040] Referring to Figure 2 and Figure 3, a limiting component 6 for restricting the sliding of the pressing plate 55 to prevent it from separating from the support column 54 is provided on the support column 54. The limiting component 6 specifically includes limiting blocks 61 provided at one ends of the four support columns 54 away from the cover plate 52, and the limiting blocks 61 are fixedly connected to the ends of the four support columns 54. A T-shaped groove 611 communicating with the four vertical side surfaces of the limiting block 61 is formed through the middle of the limiting block 61 in the horizontal direction, and the larger cross-sectional dimension end of the T-shaped groove 611 is close to the pressing plate 55. A docking head 62 is integrally connected to the end of the telescopic rod of the air cylinder 41, and the docking head 62 is slidably connected in the T-shaped groove 611.
[0041] Further, two rubber cushion blocks 7 are symmetrically and fixedly provided at both ends of the cover plate 52 along the length direction of the T-shaped groove 611 to ensure that the pressing block does not collide with the cover plate 52 during the punching process of the mold on the mud trough plate 1, for protecting the integrity of the mold parts and providing a punching buffer effect. The rubber stop block is of a conical structure, and its cross-sectional area continuously decreases along the vertical direction upward, so as to make the buffer effect better.
[0042] Refer to Figure 4 and Figure 5 , a pushing mechanism 8 for pushing the mud trough plate 1 out of the limiting groove 53 is provided on the base 2, which includes a column 81 fixedly installed at one end of the base 2 along the length direction of the cushion plate 51. A square hole 811 is formed through the column 81 along the length direction of the cushion plate 51, and a pushing rod 82 is slidably inserted into the square hole 811. One end of the pushing rod 82 extends into the limiting groove 53 and abuts against the mud trough plate 1.
[0043] Refer to Figure 4 and Figure 6 , further, a receiving block 9 for placing the mud trough plate 1 pushed out of the limiting groove 53 by the pushing rod 82 is fixedly connected to one end of the cushion plate 51 away from the column 81. A receiving groove 91 communicating with the bottom end surface of the limiting groove 53 is formed through the upper end surface of the receiving block 9 along the sliding direction of the mud trough plate 1, and the receiving groove 91 is also adapted to the shape of the mud trough plate 1, so that the mud trough plate 1 slides more smoothly.
[0044] Refer to Figure 4 and Figure 6 , furthermore, four positioning holes 92 are symmetrically formed through both sides of the receiving groove 91 at the upper end of the receiving block 9. Positioning bolts are respectively inserted into the two positioning holes 93 on the same side, and the two positioning bolts are jointly connected to a positioning block 93. Waist-shaped holes 931 slidably matched with the positioning bolts are formed through both of the two positioning blocks 93 located on both sides of the receiving groove 91, so as to facilitate adjusting the distance between the two positioning blocks 93 to form a clamping effect on the mud trough plate 1.
[0045] Since the positioning bolt mainly functions to fix the positioning block 93 and belongs to a relatively common standard part, it is not shown in the attached drawings of this embodiment.
[0046] The implementation principle of a punching die for automobile parts in an embodiment of this application is as follows:
[0047] The air cylinder 41 drives the pressing plate 55 to slide back and forth along the axis direction of the support column 54, causing the punching block 56 fixedly connected to the pressing plate 55 to move up and down, and driving the punching head 57 located at the bottom of the punching block 56 to perform a punching operation on the mud groove plate 1 located in the limiting groove 53. During this process, the backing plate 51 and the cover plate 52 are always connected together and limit the mud groove plate 1 located inside the limiting groove 53 in the punching direction.
[0048] When the mud groove plate 1 is formed by punching, the pushing rod 82 located on the column 81 will push it out to the receiving groove 91 on the receiving block 9.
[0049] Moreover, since the mounting plate 4 and the docking head 62 are respectively slidably connected to the T-shaped grooves 611 on the two support plates 3 and the limiting block 61, the mounting plate 4 and the air cylinder 41 can be disassembled and replaced at any time to ensure the adjustability of the die.
[0050] The above are all preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: Any equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
