Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts stamping technology, and more specifically to an automotive parts stamping processing device. Background Technology
[0002] Stamping is a key process in automobile manufacturing. 60% to 70% of the metal parts of automobiles need to be formed by stamping. On average, there are about 1,500 stamped parts on each car. They are widely used in body panels, interior support parts, structural reinforcement parts, seat systems, instrument systems, exhaust systems and powertrains. Stamping is a production equipment that uses molds to apply external force to raw materials such as sheet metal, causing them to undergo plastic deformation or separation, thereby obtaining automobile parts with the required shape, size and performance.
[0003] The shortcomings of the existing technology: The stamping processing equipment in the existing technology usually performs reciprocating motion continuously, impacting the operating table and stamping template. Therefore, the continuous stamping operation of the equipment can easily cause the edge of the operating table to crack. At the same time, during the stamping process of the sheet metal, the uneven distribution of material may lead to uneven stamping pressure, which affects the product quality of the parts. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a stamping processing device for automotive parts, which solves the problems in the prior art where the continuous stamping operation of the existing device easily leads to cracking of the edge of the operating table, and uneven material distribution easily leads to uneven stamping pressure, affecting the quality of the parts.
[0005] This utility model provides the following technical solution: a stamping processing device for automotive parts, including an operating table and a stamping machine set at its top, a stamping plate is fixedly connected to the extended end of the stamping machine, a stamping groove is opened in the middle of the top of the operating table, buffer components are provided at both ends of the stamping plate, pressing grooves are opened on both sides of the stamping groove, and a stamping table is provided in the inner cavity of the stamping groove.
[0006] The buffer assembly includes a fixing rod fixedly connected to the side of the stamping plate. A pressure plate is fixedly connected to one side of the bottom end of the fixing rod, and two first buffer pads are fixedly connected to the other side of the bottom end of the fixing rod. A protective edge is fixedly connected to one side of the inner wall of the pressure plate.
[0007] Preferably, the position of the pressing plate corresponds to the position of the pressing groove and is movably connected to its inner cavity, and the protective edge is located at the connection between the fixed rod and the stamping plate.
[0008] Preferably, the stamping plate is located above the stamping table, and the stamping plate 3 is movably connected to the inner cavity of the stamping groove.
[0009] Preferably, the inner wall of the protective edge is arc-shaped, the top edge of the stamping table is arc-shaped, and the protective edge is movably connected to the top edge of the stamping table.
[0010] Preferably, a nitrogen spring is fixedly connected to the bottom end of the first buffer pad, and a second buffer pad is sleeved in the middle of the nitrogen spring. The nitrogen spring is set on the operating table, and the second buffer pad is located at the top of the operating table.
[0011] Preferably, the outer surface of the stamping machine is provided with a fixing plate, and the bottom end of the fixing plate is provided with two auxiliary hydraulic push rods, the protruding ends of the auxiliary hydraulic push rods being fixedly connected to the top two sides of the stamping plate.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This utility model prevents excessive instantaneous impact force from the stamping plate by incorporating a buffer assembly. When the stamping machine pushes the stamping plate downwards, the nitrogen springs on both sides absorb the impact force of the stamping plate, providing a certain buffering effect and ensuring a smoother downward stamping process. At the same time, when the stamping plate is stamped downwards, the first and second buffer pads prevent the stamping plate from continuously impacting the operating table and stamping table, avoiding damage to the operating table and stamping template caused by the strong impact force of continuous reciprocating motion, effectively increasing the service life of the device. In addition, the buffer assembly effectively reduces the vibration and noise generated by the device.
[0014] 2. This utility model applies appropriate pressing force to the material at the edge of the device by providing a pressing plate and a pressing groove, preventing wrinkling during the stamping process. At the same time, when the stamping machine drives the stamping plate downward for stamping operation, two auxiliary hydraulic push rods push the two sides of the stamping plate to increase the pressure on both sides of the stamping plate, ensuring that the pressure on the stamped plate is more uniform. This avoids uneven force distribution on both sides of the material due to uneven stamping plate distribution, which would affect the product quality after stamping. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The stamping processing device for automotive parts involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] This utility model provides a stamping device for automotive parts, such as... Figure 1 - Figure 4 As shown, it includes an operating table 1 and a stamping machine 2 set on its top. A stamping plate 3 is fixedly connected to the extended end of the stamping machine 2. A stamping groove 4 is opened in the middle of the top of the operating table 1. Buffer components 5 are provided at both ends of the stamping plate 3. Pressing grooves 6 are opened on both sides of the stamping groove 4. A stamping table 7 is provided in the inner cavity of the stamping groove 4.
[0022] Furthermore, such as Figure 2 and Figure 3 As shown, the buffer assembly 5 includes a fixing rod 51 fixedly connected to the side of the stamping plate 3. A pressure plate 52 is fixedly connected to one side of the bottom end of the fixing rod 51, and two first buffer pads 53 are fixedly connected to the other side of the bottom end of the fixing rod 51. A protective edge 54 is fixedly connected to one side of the inner wall of the pressure plate 52.
[0023] Furthermore, such as Figure 3 As shown, the position of the pressing plate 52 corresponds to the position of the pressing groove 6 and is movably connected to its inner cavity. The protective edge 54 is located at the connection between the fixed rod 51 and the stamping plate 3. During the use of the device, the extension of the protruding end of the stamping machine 2 pushes the stamping plate 3 to move downward, and performs a stamping operation on the plate on the stamping table 7. While the stamping plate 3 is stamping downward, it drives the pressing plates 52 on both sides to move downward into the inner cavity of the pressing groove 6. The pressing plates 52 prevent insufficient pressure on both sides of the stamping plate 3 and the stamping table 7, which would cause wrinkles or other issues to appear on the side of the stamped plate.
[0024] Furthermore, such as Figure 2As shown, the stamping plate 3 is located above the stamping table 7. The stamping plate 3 is movably connected to the inner cavity of the stamping groove 4. The stamping groove 4 determines the position of the stamping table 7, ensuring that the stamping position of the stamping plate 3 remains consistent each time, thus preventing the stamped parts from shifting and affecting the product quality of the parts.
[0025] Furthermore, such as Figure 3 As shown, the inner wall of the protective edge 54 is set to be arc-shaped, and the top edge of the stamping table 7 is set to be arc-shaped. The protective edge 54 is movably connected to the top edge of the stamping table 7. Since the stamping process requires repeated stamping operations, when the stamping plate 3 stamps the stamping table 7 downwards, the edge of the stamping table 7 is subjected to pressure impact for a long time, which is prone to cracking. The protective edge 54 with arc-shaped inner wall and the arc-shaped edge effectively prevent the right-angle edge from being squeezed and easily cracking.
[0026] Furthermore, such as Figure 3 and Figure 4 As shown, a nitrogen spring 55 is fixedly connected to the bottom end of the first buffer pad 53, and a second buffer pad 56 is sleeved in the middle of the nitrogen spring 55. The nitrogen spring 55 is set on the operating table 1, and the second buffer pad 56 is located at the top of the operating table 1. When the nitrogen spring 55 is subjected to external force, the nitrogen will generate pressure changes in the container, thereby generating elastic force. When the external force disappears, the nitrogen spring will return to its original state. During the downward pressing process of the stamping plate 3, the nitrogen spring 55 can effectively absorb and release the impact energy of the stamping plate 3 through the compression and expansion process of nitrogen, playing a buffering role. At the same time, it can reduce vibration and noise, and prevent the stamping plate 3 from being pressed too hard, which could cause the plate being pressed to crack. At the same time, the nitrogen spring 55 effectively increases the uniformity of pressure during the downward pressing process of the stamping plate 3. The first buffer pad 53 and the second buffer pad 56 prevent the impact force generated between the stamping plate 3 and the operating table 1 from causing damage to the operating table 1, effectively increasing the service life of the device.
[0027] Furthermore, such as Figure 1 As shown, a fixed plate 8 is provided on the outer surface of the stamping machine 2. Two auxiliary hydraulic push rods 9 are provided at the bottom end of the fixed plate 8. The extended ends of the auxiliary hydraulic push rods 9 are fixedly connected to the top two sides of the stamping plate 3. When the stamping plate 3 is continuously driven by the stamping machine 2 to move up and down reciprocally, the two auxiliary hydraulic push rods 9 push the two sides of the stamping plate 3 to increase the pressure on both sides of the stamping plate 3. This ensures that the pressure on the stamped plate is more uniform and avoids uneven force distribution on both sides of the material due to uneven distribution of the stamped plate, which would affect the product quality after stamping.
[0028] The working principle of this utility model is as follows: First, the stamping table 7 is installed in the inner cavity of the stamping groove 4. The sheet metal to be stamped is placed on the stamping table 7. Then, the stamping machine 2 is started. Through the extension and retraction of the output end of the stamping machine 2, the stamping plate 3 is driven downward to stamp the sheet metal on the stamping table 7, so that the sheet metal is stamped into automotive parts. During the stamping process, the stamping plate 3 drives the pressure plates 52 on both sides to move downward into the inner cavity of the pressure groove 6. The pressure plates 52 prevent insufficient pressure on both sides of the stamping plate 3 and the stamping table 7, which would cause wrinkles or other problems on the sides of the stamped sheet metal. The stamping plate 3 is continuously driven by the stamping machine 2 to reciprocate up and down to perform stamping operations on automotive parts. At the same time, two auxiliary hydraulic push rods 9 push the sides of the stamping plate 3 to increase the pressure on both sides of the stamping plate 3, ensuring that The pressure on the stamped sheet is more uniform. Since the edge of the stamping table 7 is subjected to pressure impact for a long time, it is prone to cracking. The protective edge 54 of the arc-shaped inner wall and the arc-shaped edge effectively prevent the right-angle edge from being squeezed and cracking. During the downward stamping process of the stamping plate 3, the stamping energy is absorbed by the nitrogen spring 55, which plays a certain buffering role. At the same time, it can reduce vibration and noise, and avoid excessive pressure of the stamping plate 3 downward, which would cause the stamped sheet to crack. At the same time, the nitrogen spring 55 effectively increases the uniformity of pressure during the downward stamping process of the stamping plate 3. The first buffer pad 53 and the second buffer pad 56 prevent the impact force generated between the stamping plate 3 and the operating table 1 from damaging the operating table 1, effectively increasing the service life of the device.
