Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts production, in particular to a stamping die for automobile parts with high plasticity. Background Art

[0002] With the rapid development of the automobile industry, stamping technology, as a major metal forming process, occupies an important position in the manufacture of automobile parts. Stamping dies are crucial tools in the stamping process, which directly affect the molding quality and production efficiency of automobile parts.

[0003] Specifically, the common auto parts stamping dies on the market currently have the following shortcomings:

[0004] A. Traditional stamping dies for auto parts are usually designed for specific parts with fixed shapes, sizes and stamping parameters. This fixed-structured die has great limitations when facing the stamping needs of various types of auto parts. For example, when it is necessary to stamp parts of different shapes or sizes, the entire die often needs to be replaced, which not only increases production costs, but also takes a lot of time for die replacement and debugging, seriously affecting production efficiency.

[0005] B. During the stamping process, the repeated stamping action of the mold will cause heat accumulation, which will increase the mold temperature. Excessive temperature will affect the performance of the mold, such as causing the mold to deform, which will in turn affect the dimensional accuracy of the stamped parts and reduce the quality of the stamped parts. At the same time, it will also shorten the service life of the mold, increase the frequency of mold maintenance and replacement, and further increase production costs.

[0006] In addition, impurities such as metal chips may be generated during the stamping process. If these impurities remain in the stamping work area, on the one hand, they will affect the surface finish of the stamped parts, and on the other hand, they may affect the matching accuracy between the mold and the parts, resulting in deviations in the size of the stamped parts. Summary of the invention

DETAILED DESCRIPTION

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] A stamping die for automobile parts with high plasticity according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0036] like Figures 1 to 8 As shown, an embodiment of the present invention provides a stamping die for automotive parts with high plasticity, a working frame 31, a fixing groove 16 is opened inside the working frame 31, a receiving plate 17 is provided inside the fixing groove 16, a first cylindrical spiral buffer 22 is provided at the bottom of the receiving plate 17, and the other end of the first cylindrical spiral buffer 22 is provided at the bottom of the inner cavity of the fixing groove 16, a part body 12 is provided inside the receiving plate 17, a fixed cylinder 1 is provided at the four corners of the inner wall of the receiving plate 17, a clamping plate 13 is provided inside the receiving plate 17, two groups of clamping plates 13 are provided, and the two groups of clamping plates 13 are clamped together on both sides of the part body 12, four groups of fixed cylinders 1 are provided, and the part body 12 is provided between the four groups of fixed cylinders 1, and a telescopic connecting rod 14 is provided on one side of the two groups of clamping plates 13.

[0037] In a specific application of the embodiment of the present invention, in the initial state, the component body 12 is first placed inside the receiving plate 17, and the two sets of clamping plates 13 are in the initial position when no external force is applied. When the component body 12 needs to be stamped, the two sets of clamping plates 13 approach the component body 12 according to the size of the component body 12 and finally tightly clamp the two sides of the component body 12. At the same time, the four sets of fixed cylinders 1 limit and position the component body 12 in space, determine the exact position of the component inside the receiving plate 17, and prevent it from moving in the horizontal direction.

[0038] During the stamping process, when the stamping force acts on the receiving plate 17, the receiving plate 17 will move downward. At this time, the first cylindrical spiral buffer 22 at the bottom of the receiving plate 17 starts to work, and the spiral structure inside the first cylindrical spiral buffer 22 has certain elasticity and damping characteristics. When the receiving plate 17 is pressed down, the spiral structure inside the buffer will be compressed, converting the stamping force into elastic potential energy and heat energy (due to the damping effect) to store and consume part of it, thereby reducing the instantaneous impact force on the component body 12.

[0039] In a possible embodiment, a limiting cylinder 4 is provided above the fixed cylinder 1, a first magnetic washer 2 is provided on the top surface of the fixed cylinder 1, a damping buffer rod 3 is provided inside the fixed cylinder 1, a matching second magnetic washer 6 is provided on the bottom surface of the limiting cylinder 4, and a plug-in rod 5 is provided inside the limiting cylinder 4.

[0040] In a specific application of the embodiment of the present invention, the limiting cylinder 4 is installed above the fixed cylinder 1. Due to the magnetic attraction of the first magnetic washer 2 and the second magnetic washer 6, the limiting cylinder 4 can be quickly and accurately positioned at a suitable position above the fixed cylinder 1, and this magnetic connection can pre-fix the relative positions of the two to a certain extent, facilitating subsequent assembly operations. At the same time, the damping buffer rod 3 is in a ready state inside the fixed cylinder 1, and the plug-in rod 5 is also in an initial position inside the limiting cylinder 4. The various components cooperate with each other to form the prototype of the overall mold structure, waiting for the start of the stamping operation.

[0041] When pressure is applied to the mold, the pressure is first transmitted to the limiting cylinder 4. The limiting cylinder 4 will not excessively move vertically downward due to the limitation of the fixed cylinder 1 below (through the relative position relationship and magnetic connection between the two). At this time, as the pressure increases, the damping buffer rod 3 slowly compresses or deforms according to its internal damping characteristics (depending on the specific structure of the damping buffer rod 3, such as hydraulic damping or elastic damping, etc.), thereby absorbing part of the stamping energy and preventing the impact force from causing excessive damage to the mold in an instant.

[0042] When the stamping operation is completed and the applied pressure is removed, the damping buffer rod 3 gradually returns to its initial state due to its own elastic recovery or hydraulic balance recovery characteristics. The limiting cylinder 4 returns to its initial relative position under the attraction of the magnetic gasket and the cooperation between other components, and the entire mold structure returns to the state before stamping, ready for the next stamping operation.

[0043] In a possible embodiment, an electric retractor control button 20 is provided inside the fixed groove 16, and the electric retractor control button 20 is electrically controlled and connected to the electric retractor 11 through a conductive line. The top surface of the inner cavity of the working cylinder body is provided with an electric retractor 11, and the working end of the electric retractor 11 is provided with a limiting top cover 7, and a vent hole 8 is opened on the side of the limiting top cover 7, and the stamping die 10 is arranged inside the limiting top cover 7; a punch body 9 is provided on the top surface of the limiting top cover 7, and a punch body control button 21 is provided inside the fixed groove 16, and the punch body control button 21 is electrically controlled and connected to the punch through a conductive line, a stamping die 10 is provided between the four groups of limiting cylinders 4, and the working end of the punch body 9 is connected to the stamping die 10, and the size of the limiting top cover 7 is smaller than the size of the receiving plate 17.

[0044] In a specific application of the embodiment of the present invention, after the receiving plate 17 descends and touches the electric retractor control button 20 and the punch body control button 21, the punch body 9 and the electric retractor 11 start working autonomously. Before stamping, the electric retractor 11 can adjust the height position of the limit cover 7 to adapt to different stamping starting state requirements. For example, if thicker automotive parts materials need to be stamped, the limit cover 7 may need to be adjusted to a higher position to provide sufficient working space for the stamping die 10.

[0045] When the stamping operation is started, the punch body 9 begins to work under the control of the electric retractor 11, and its working end applies pressure to the stamping die 10. The four groups of limit cylinders 4 limit the lateral movement of the stamping die 10 to ensure the accuracy of the stamping direction. On the one hand, the limit cover 7 is controlled by the position of the electric retractor 11, and on the other hand, the punch body 9 on its top surface applies downward pressure, so that the stamping die 10 can accurately perform stamping operations on automotive parts placed in appropriate positions. At the same time, the air vents 8 continuously balance the internal air pressure to ensure the stability of the stamping process (during the stamping process, the air vents on the side of the limit cover can ensure the air pressure balance during the stamping process. If there are no air vents, the air inside the limit cover 7 will be compressed during stamping, which may produce a large reaction force, affecting the stamping effect or causing damage to the components.).

[0046] After the stamping is completed, the punch body 9 stops working, and the electric retractor 11 can adjust the position of the limit top cover 7 again as needed, so as to facilitate the removal of the stamped automobile parts and components and prepare for the next stamping operation.

[0047] In a possible embodiment, a limiting groove 15 is opened in the inner cavity of the working frame 31, and extension plates 24 are provided on both sides of the outer wall of the receiving plate 17, and the extension plates 24 are arranged inside the limiting groove 15. A second cylindrical spiral buffer 23 is provided at the bottom of the extension plate 24, and the other end of the second cylindrical spiral buffer 23 is arranged at the bottom of the inner cavity of the limiting groove 15; a hydraulic cylinder 19 is provided inside the working frame 31, and the hydraulic cylinder 19 is provided in two groups. The working end of the hydraulic cylinder 19 is provided with an L-shaped limiting plate 18, and the shape of the L-shaped limiting plate 18 is set to be concave, and the other end of the L-shaped limiting plate 18 is clamped to the outer side of the receiving plate 17.

[0048] In a specific application of the embodiment of the present invention, when the stamping die 10 is not working, the receiving plate 17 is located in the limiting groove 15 through the extension plate 24, the second cylindrical spiral buffer 23 is in a natural state, and the L-shaped limiting plate 18 of the hydraulic cylinder 19 is clamped on the outside of the receiving plate 17 to fix the receiving plate 17 in the initial position in the working frame 31. When the stamping operation of the component body 12 is performed, the equipment will apply pressure to the workpiece on the receiving plate 17. At this time, the receiving plate 17 will be subjected to downward pressure, and because the receiving plate 17 is constrained by the L-shaped limiting plate 18, it can only move downward in the vertical direction.

[0049] As the receiving plate 17 moves downward, the second cylindrical spiral buffer 23 at the bottom of the extension plate 24 begins to be compressed, and the spiral structure inside the buffer undergoes elastic deformation, converting part of the stamping energy into elastic potential energy for storage, thereby reducing the direct impact of the receiving plate 17 on other components. At the same time, the L-shaped limit plates 18 of the two sets of hydraulic cylinders 19 continue to apply a fixing force to the receiving plate 17 to prevent the receiving plate 17 from horizontal displacement or rotation during the stamping process, ensuring that the stamping operation is carried out according to the predetermined trajectory.

[0050] When the stamping operation is finished, the pressure applied to the stamping die 10 and the receiving plate 17 is removed. At this time, the compressed second cylindrical spiral buffer 23 releases elastic potential energy, pushing the receiving plate 17 to move upward back to the initial position, and the L-shaped limit plate 18 of the hydraulic cylinder 19 still keeps the receiving plate 17 clamped and fixed, preparing for the next stamping operation.

[0051] In a possible embodiment, the vacuum cleaner 25 and the cooler 28 are respectively arranged on both sides of the working frame 31, the working end of the vacuum cleaner 25 is provided with an impurity conveying pipe 26, and the working end of the cooler 28 is provided with an aerosol conveying pipe 29, and the impurity conveying pipe 26 and the aerosol conveying pipe 29 are both provided with filter plates 27 inside.

[0052] In a specific application of the embodiment of the present invention, a suction generating device is provided inside the vacuum cleaner 25. When the motor is started, the fan rotates at a high speed, forming a negative pressure zone at the entrance of the impurity conveying pipe 26. Under the action of the negative pressure, impurities (such as metal chips, dust, etc.) in the working area are sucked into the impurity conveying pipe 26. Since a filter plate 27 is provided inside the impurity conveying pipe 26, larger impurity particles will be blocked by the filter plate 27 to avoid damage to the internal structure of the vacuum cleaner 25. Impurities blocked by the filter plate 27 will gradually accumulate on the side of the filter plate 27 close to the working area, while the filtered air can continue to enter other parts of the vacuum cleaner (such as the exhaust passage, etc.) through the filter plate 27, and finally the impurities and air are separated, so as to achieve the purpose of cleaning the working area.

[0053] The cooler 28 has a corresponding aerosol generating device inside (a cooling gas cooler forms aerosol by compressing gas and spraying the gas at high speed through a valve or nozzle; a cooling liquid mist cooler forms tiny droplets by atomizing the coolant, and the aerosol is transported to the working area or the mold surface through the aerosol delivery pipe 29). When the aerosol contacts the high-temperature stamping die 10 or the working area, the cooling medium (gas or liquid) in the aerosol will change state or conduct heat with the high-temperature object. For example, the droplets in the coolant mist will absorb heat and evaporate, or the cooling gas will exchange heat with the surface of the high-temperature stamping die 10, thereby taking away heat and reducing the temperature of the mold or the working area.

[0054] In a possible implementation, fixing columns 33 are provided at four corners of the bottom surface of the working frame 31 , wear-resistant pads 30 are provided on the bottom surfaces of the four fixing columns 33 , and wear-resistant grooves are provided on the bottom surfaces of the wear-resistant pads 30 .

[0055] In a specific application of the embodiment of the present invention, during the stamping process, the force applied by the equipment is first transmitted to the working frame 31 of the mold, and the fixed columns 33 at the four corners of the bottom surface of the working frame 31 transmit the force from the working frame 31 vertically downward to the work surface. Since the four fixed columns 33 are evenly distributed at the four corners of the bottom surface of the working frame 31, the uniform transmission of force can be ensured, so that the mold can maintain a stable working state on the workbench. For example, when stamping a larger-sized automobile body cover, the stamping pressure may reach several tons or even tens of tons. The fixed columns 33 can effectively and evenly distribute such a huge pressure to the work surface, avoiding deformation of the work surface or loose connection between the mold and the workbench due to excessive local pressure.

[0056] As the number of stamping increases, the wear pad 30, as a buffer and wear-resistant intermediate layer, bears most of the friction through its own wear-resistant material properties (such as the use of special alloy materials or composite materials). The wear-resistant pattern further improves the wear resistance by increasing the friction and contact area between the wear-resistant pad 30 and the work surface. During each stamping process, the slight friction and deformation between the wear-resistant pattern on the wear-resistant pad 30 and the work surface can effectively consume energy, while preventing the bottom surface of the fixing column 33 from directly wearing excessively with the work surface, thereby ensuring the stability and precision of the mold during long-term use.

[0057] In a possible implementation manner, a control panel 32 is provided on the outer wall of the working frame 31 , and the control panel 32 is electrically controlled and connected to the hydraulic cylinder 19 , the dust collector 25 , and the cooler 28 through conductive wires.

[0058] In a specific application of the embodiment of the present invention, the hydraulic cylinder 19, the vacuum cleaner 25 and the cooler 28 used in the device are mature existing technologies. The working principles of the hydraulic cylinder 19, the vacuum cleaner 25 and the cooler 28 are also well known to those skilled in the art and will not be described in detail here.

[0059] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0060] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
