Description

Technical Field

[0001] The invention relates to the technical field of automobile component stamping, in particular to one-step stamping forming equipment for automobile components and a use method thereof. Background Art

[0002] Automobiles are mainly composed of various accessories. Currently, many parts of automobiles can be directly stamped from metal materials, such as spring trays, spring seats, spring brackets, end covers, compression valve covers, compression valve sleeves, oil seal seats, bottom covers and other parts.

[0003] In the prior art, such as the Chinese patent application number: CN202010474061.7 "A stamping and forming device for new energy vehicle parts and its use method", includes a workbench, a stamping platform, a column, and a stamping cylinder. The column is vertically fixed on the side wall of the workbench, the stamping platform is fixed on the workbench, and the stamping cylinder is fixed at the bottom of the column. An upper mold is fixed on the piston rod at the output end of the stamping cylinder, and evenly distributed stamping rods are fixed on the bottom of the upper mold; the present invention transports the material to be stamped and formed through a conveying mechanism, and under the drive of the reciprocating drive mechanism, drives the first mounting plate to transport the material to the conveying trough and the lower mold in turn, and uses the stamping rod to stamp and form the material, and at the same time, the stamped material is transported out of the lower mold through the second mounting plate. The present invention can realize the automatic taking and placing of materials, and has the characteristics of high production efficiency.

[0004] However, in the prior art, during the stamping process of the stamping platform, when the number of processes for bending stamped parts increases, the cumulative error caused by the deviation of each process will also increase. Therefore, the different arrangement orders before and after the process will have a great impact on the size. Traditional stamping equipment has a maximum pressure limit. Therefore, if the material of the plate is relatively hard, the desired shape may not be directly obtained by stamping in this way. At this time, multiple stampings are required. Multiple stampings will not only directly affect the structural strength of the plate, but also lead to an extension of the stamping process time. Moreover, when it is necessary to punch out a bent part with a hole, if the hole is punched out first and then bent, the shape and position size of the hole will be slightly deformed when the part is bent, resulting in the shape of the hole not meeting the requirements. If the part is bent first and then punched, the shape of the part will be changed over a large area, which will affect the normal punching. Summary of the invention

[0005] The object of the present invention is to provide a one-time stamping forming device for automobile parts and a method of using the same, so as to solve the problem that during the stamping forming process of the stamping platform proposed in the above-mentioned background technology, when the number of processes for bending stamped parts increases, the cumulative error caused by the deviation of each process will also increase.

Therefore, if the material of the plate is relatively hard, the desired shape may not be directly obtained by stamping in this way. At this time, multiple stampings are required. Multiple stampings will not only directly affect the structural strength of the plate, but also lead to an extension of the stamping process time. Moreover, when it is necessary to punch out a bent part with a hole, if the hole is punched out first and then bent, the shape and position size of the hole will be slightly deformed when the part is bent, resulting in the shape of the hole not meeting the requirements. If the part is bent first and then punched, the shape of the part is changed over a large area at this time, which will affect the normal punching.

[0008] Preferably, a forming die is provided on the outer wall of the limiting pillar, the forming die is located on one side of the stamping platform, the forming die is located inside the limiting box, and a demoulding platform is provided between the forming die and the limiting box.

[0009] Preferably, the punching device includes a driving motor, one end of the driving motor is fixedly connected to a carrying platform, an extension panel is fixedly installed on the top of the carrying platform, a driving gear is movably installed between the carrying platform and the extension panel, and a driving rod of the driving motor is connected to the inside of the driving gear.

[0012] Preferably, the other end of the transmission support rod is movably connected to an external auxiliary rod, the number of the external auxiliary rods is set to four, and the angle between the four external auxiliary rods is ninety degrees, and reinforcement rods are fixedly connected to the outer walls of three of the four external auxiliary rods.

[0013] Preferably, an impact drill bit is fixedly mounted on one end of the external auxiliary rod, an anti-drop ring is movably mounted at the junction of the impact drill bit and the external auxiliary rod, and a limiting protrusion is fixedly mounted on the other end of the external auxiliary rod.

[0014] Preferably, the external auxiliary rod and the positioning hole are located on the same straight line, and the impact drill bit passes through the partition baffle through the provided positioning hole and is connected to the inside of the stamping platform.

[0015] Preferably, the four external auxiliary rods surround the movable rod, and one end of the mounting and connecting platform is fixedly connected to one side of the stamping platform.

[0016] A method for using a one-step stamping forming device for automobile parts comprises the following steps:

[0017] S1. Before use, pull the perspective panel and move it along the direction of the limit guide rail to expose the gap between the forming die and the stamping platform. Then put the plate to be stamped between the forming die and the stamping platform and fix it. Then start the cylinder to quickly push the movable rod to move, so as to drive the stamping platform to move, so that the stamping platform itself can obtain a certain amount of kinetic energy.

[0018] S2. When the active rod drives the stamping platform to move, the stamping platform itself will also operate, pushing the stamping die inside it toward the forming die. When the stamping platform comes into contact with the forming die, the forming die will not only be subjected to the pressure of the stamping platform, but also to the impact force when the stamping platform moves. The impact force and pressure combined can produce a greater stamping effect, so that the sheet can be formed into the shape of the finalized die at one time;

[0019] S3. When the punching platform completes the punching, the punching device starts to operate, and the driving motor drives the driving gear to rotate, and the driving gear pushes the docking gear plate to move, so as to achieve the purpose of pushing the transmission support rod to move. Since the other end of the transmission support rod is connected to the external auxiliary rod, and the external auxiliary rod is connected to the other three external auxiliary rods through the reinforcement rod, when the external auxiliary rod is pushed by the transmission support rod, the impact drill bit will be pushed into the interior of the stamping platform to complete the punching of the plate. At this time, the stamping platform and the plate are still in contact, so there will be no situation where the bending of the plate affects the punching and the bending of the plate affects the hole shape.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, the movable rod is pushed to move by the cylinder, so that the stamping platform itself has a certain kinetic energy before stamping. When the stamping platform contacts the forming mold, the mold will be subjected to the impact force of the stamping platform and the pressure of the stamping platform itself. The impact force is in the same direction as the pressure of the stamping platform on the forming mold, and can be superimposed together to obtain a stronger stamping force. Compared with traditional stamping equipment, this method has a stronger stamping force and can further break through the upper limit of pressure, so that the sheet can be directly stamped into the shape of the forming mold in one stamping, avoiding the need for secondary processing of the sheet, and helping to protect the structural strength of the sheet by reducing damage to the sheet.

[0022] 2. In the present invention, the punching device is connected to the stamping platform through the positioning hole on the partition baffle, and punching is performed immediately after the stamping is completed. The pressure of the stamping platform on the plate at this time is used to avoid the influence of punching on the shape of the plate. This method can effectively avoid the problem of punching out holes first and then bending, and the shape and position size of the holes will be slightly deformed when the parts are bent. Concentrating the two processes together can avoid the problem of bending the parts first and then punching, which will affect the shape of the parts and the problem of affecting normal punching.

Finally, the operator pulls open the perspective panel 9 to take out the parts after stamping.

[0040] Example 3

[0041] according to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7As shown, the punching device 4 includes a driving motor 41, one end of the driving motor 41 is fixedly connected to a carrying platform 49, an extension panel 413 is fixedly installed on the top of the carrying platform 49, a driving gear 414 is movably installed between the carrying platform 49 and the extension panel 413, a driving rod of the driving motor 41 is connected to the inside of the driving gear 414, a positioning bearing 412 is fixedly installed on one side of the extension panel 413, one end of the driving gear 414 is rotatably connected to the inside of the positioning bearing 412, one side of the carrying platform 49 is fixedly connected to an installation connection platform 415, the other side of the carrying platform 49 is fixedly installed with a limiting platform 411, the top of the limiting platform 411 is slidably connected to a docking tooth plate 410, one end of the docking tooth plate 410 is fixedly connected to a synchronization panel 42, and one side of the synchronization panel 42 is fixedly installed There is a transmission support rod 43, and the other end of the transmission support rod 43 is movably connected to an external auxiliary rod 44. The number of the external auxiliary rods 44 is set to four, and the angle between the four external auxiliary rods 44 is ninety degrees. Reinforcement rods 45 are fixedly connected to the outer walls of three of the four external auxiliary rods 44. An impact drill bit 46 is fixedly installed at one end of the external auxiliary rod 44, and an anti-drop ring 47 is movably installed at the intersection of the impact drill bit 46 and the external auxiliary rod 44. A limiting protrusion 48 is fixedly installed on the other end of the external auxiliary rod 44. The external auxiliary rod 44 and the positioning hole 39 are located on the same straight line. The impact drill bit 46 passes through the provided positioning hole 39 and penetrates the partition baffle 38 to be connected to the inside of the stamping platform 36. The four external auxiliary rods 44 surround the movable rod 35, and one end of the mounting connection platform 415 is fixedly connected to one side of the stamping platform 36.

[0042] In this embodiment, the punching device 4 starts to operate after the punching platform 36 and the forming mold 311 are in contact with each other. The entire punching device 4 is installed on one side of the punching platform 36 by installing the connecting platform 415. Four external auxiliary rods 44 surround the movable rod 35 to avoid affecting the movable rod 35 to drive the punching platform 36 to move. During operation, the driving motor 41 drives the driving gear 414 to rotate. The position of the driving gear 414 is determined by the positioning bearing 412 installed on the extension platform 411. The rotation of the driving gear 414 will directly push the docking tooth plate 410 to move along the direction of the limit platform 411. Since the docking tooth plate 410 is connected to the transmission support rod 43 through the synchronization panel 42, when the docking tooth plate 410 moves, it will drive the transmission support rod 43 to move together. Since the other end of the transmission support rod 43 is connected to the external auxiliary rod 44, and the external auxiliary rod 44 is connected to the other three external auxiliary rods 44 through the reinforcement rod 45, when the external auxiliary rod 44 is pushed by the transmission support rod 43, the impact drill bit 46 will be pushed into the interior of the stamping platform 36 to complete the punching of the plate. At this time, the stamping platform 36 and the plate are still in contact, so there will be no situation where the bending of the plate affects the punching and the bending of the plate affects the hole shape. When the impact drill bit 46 enters the inside of the stamping platform 36, the limiting protrusion 48 at the other end will limit the maximum moving range of the entire external auxiliary rod 44 into the stamping platform 36 to avoid the external auxiliary rod 44 from breaking, and the impact drill bit 46 is connected to the external auxiliary rod 44 through the anti-drop ring 47, which is convenient for disassembly and replacement.

[0043] The usage and working principle of the device are as follows: before use, pull the perspective panel 9 to move along the direction of the limiting guide rail 12 to expose the gap between the forming mold 311 and the stamping platform 36, and then put the plate to be stamped between the forming mold 311 and the stamping platform 36 and fix it, then start the cylinder 33 to quickly push the movable rod 35 to move, thereby driving the stamping platform 36 to move, so that the stamping platform 36 itself obtains a certain amount of kinetic energy. When the movable rod 35 drives the stamping platform 36 to move, the stamping platform 36 itself will also operate to push the stamping mold inside it toward the forming mold. When the stamping platform 36 comes into contact with the forming mold 311, the forming mold 311 will not only be subjected to the pressure of the stamping platform 36, but also to the impact force when the stamping platform 36 moves. The impact force and pressure are combined And then a greater stamping effect can be produced, so that the sheet can be formed into the shape of the finalized mold at one time. When the stamping platform 36 completes the stamping, the punching device 4 starts to operate, and the driving motor 41 drives the driving gear 414 to rotate, and the driving gear 414 pushes the docking gear plate 410 to move, so as to achieve the purpose of pushing the transmission support rod 43 to move. Since the other end of the transmission support rod 43 is connected to the external auxiliary rod 44, and the external auxiliary rod 44 is connected to the other three external auxiliary rods 44 through the reinforcement rod 45, when the external auxiliary rod 44 is pushed by the transmission support rod 43, the impact drill bit 46 will be pushed into the interior of the stamping platform 36 to complete the punching of the sheet. At this time, the stamping platform 36 and the sheet are still in contact, so there will be no situation where the bending sheet affects the punching and the bending sheet affects the hole type.

When the stamping platform (36) comes into contact with the forming die (311), the forming die (311) will not only be subjected to the pressure of the stamping platform (36), but also to the impact force when the stamping platform (36) moves. The impact force and the pressure are combined to produce a greater stamping effect, so that the sheet can be formed into the shape of the finalized die at one time; S3. After the punching platform (36) completes the punching, the punching device (4) starts to operate, the driving motor (41) drives the driving gear (414) to rotate, and the driving gear (414) pushes the docking tooth plate (410) to move, so as to achieve the purpose of pushing the transmission support rod (43) to move. Since the other end of the transmission support rod (43) is connected to the external auxiliary rod (44), and the external auxiliary rod (44) is connected to the other three external auxiliary rods (44) through the reinforcement rod (45), when the external auxiliary rod (44) is pushed by the transmission support rod (43), the impact drill bit (46) will be pushed into the inside of the punching platform (36) to complete the punching of the plate. At this time, the punching platform (36) and the plate are still in contact, so there will be no situation where the bending of the plate affects the punching and the bending of the plate affects the hole shape.
