Description

Technical Field

[0001] The present invention relates to the technical field of stamping dies, and in particular to a stamping die for producing electromechanical products. Background Art

[0002] In modern manufacturing, stamping technology is widely used in numerous fields, including automotive, electronics, and aerospace, thanks to its high efficiency, high precision, and ability to achieve large-scale production. As the core equipment in the stamping process, stamping dies directly determine the quality and production efficiency of stamped products.

[0003] In the traditional stamping process, when the die and sheet metal begin to contact, the stamping force is instantly applied to the sheet metal. Due to the extremely complex stress state of the sheet metal in the initial stage, the stress distribution in the contact area between the die and the sheet metal is extremely uneven, often resulting in excessive pressure in localized areas of the sheet metal. This uneven stamping force can easily cause localized deformation of the sheet metal, resulting in dents and warping. Summary of the Invention

The telescopic cylinders are provided with two groups, one group of telescopic cylinders is connected to the top surface of the die, and the end of the telescopic cylinder is connected to a first pressing plate, and the other group of telescopic cylinders is connected to the top surface of the die base, and the end of the telescopic cylinder connected to the top surface of the die base is connected to a second pressing plate, and one side of the second pressing plate is connected to a guide groove, and a connecting block is provided inside the guide groove, and a die assembly is embedded in the connecting block, and the die assembly includes a suspension rod, and the bottom end of the suspension rod is connected to a pressing plate, and the pressing plate is located between the punch and the stamping plate, so the suspension rod is connected in a transverse sliding manner inside the guide groove.

[0006] Furthermore, the mutual approach between the die and the die base drives the first pressing plate and the second pressing plate to approach each other. The first pressing plate and the second pressing plate are used to clamp and fix the stamping plate. One side of the stamping plate is attached to the die, and the other side is attached to the second pressing plate.

[0007] Furthermore, the die and punch are matched, and the punch is used to punch the stamping plate. During the stamping process, the punch penetrates the through hole opened on the surface of the stamping plate until it passes through the stamping plate and fits with the die.

[0008] Furthermore, the inner wall of the pressing plate is filled with magnets, and the pressing plate is adsorbed on one side of the stamping plate through the magnets. The pressing plate moves by sliding inside the guide groove through the suspension rod. A limiting device is provided on the suspension rod, and the limiting device can limit the position of the suspension rod in the guide groove.

[0009] Furthermore, an oil tank is provided inside the press plate, the oil tank is evenly distributed inside the press plate, the oil tank is filled with lubricating liquid, a cover plate is connected to the top of the press plate, the cover plate is used to cover the top opening of the oil tank, the cover plate and the press plate are slidably connected, and a reset structure is provided at the connection, the reset structure is used to cover the cover plate on the top opening of the oil tank.

[0010] Furthermore, a push plate is connected to the top of the punch, a through groove is provided on the die base, and the push plate is used to push the cover plate away from the top opening of the oil tank.

[0011] Furthermore, the upper surface of the guide plate is also connected to a photoelectric component, which includes a supporting column, a guide rod embedded in the interior of the supporting column, and a parallel lamp connected to the bottom end of the guide rod, which is suspended on the bottom end of the supporting column through the guide rod.

[0012] Furthermore, the parallel lamp is arranged between the mold base and the guide plate, and the parallel lamp slides inside the supporting column through the guide rod to achieve longitudinal movement.

[0013] Furthermore, the parallel lamp emits parallel light, which passes through the die base and irradiates the die plate. The projection generated by the parallel light irradiating the die plate is projected onto the stamping plate.

[0014] Furthermore, a photoelectric sensor transmitting end and a receiving end are installed inside the parallel lamp. The photoelectric sensor transmitter transmits a light signal, which is reflected after contacting the stamping plate and is finally received by the photoelectric sensor receiving end.

[0015] Compared with the prior art, the beneficial effects of the present invention include: the set pressing plate can cover the stamping surface of the stamping plate during stamping, thereby limiting the warping of the stamping plate caused by the acting force, eliminating the warping of the stamping plate, reducing deformation, avoiding damage to the stamping plate structure caused by excessive pulling of the internal structure, and maximizing the stability of the structure of the stamping part. Secondly, as the punch passes through the inside of the pressing plate, it pushes the movement of the cover plate, so that the oil inside the oil tank can flow to the corresponding through hole in a targeted manner, which can reduce the friction between the punch and the die, and also reduce the friction between the punch and the pressing plate, thereby improving the lubrication effect and reducing the wear of the mold.

[0022] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0023] According to one embodiment of the present invention, Figure 1-12A stamping die for producing electromechanical products includes a die 11 and a guide plate 14. A guide post 12 is connected to the side of the die 11. A die base 13 is connected to the guide post 12 away from the die 11. The guide post 12 is used to connect the die 11 and the die base 13. A punch 15 is embedded in the die base 13. A stamping plate 16 is embedded between the die 11 and the punch 15. The punch 15 and the die base 13 are slidably connected. The guide plate 14 is installed on the operating platform and is used to support the punch 15. It is slidably connected to the punch 15. When the stamping plate 16 is stamped, the stamping plate 16 is embedded between the die 11 and the punch 15. As the punch 15 and the die 11 continue to approach each other, the punch 15 cuts the stamping plate 16, thereby stamping the stamping plate 16. In order to increase the accuracy of the stamping, the stamping plate 16 is fixed by the fixing component 3. The fixed stamping plate 16 can reduce shaking during the stamping process, thereby making the landing point of the punch 15 more accurate.

[0024] The top surface of the die 11 is connected to a fixing assembly 3, which includes a telescopic cylinder 31. The telescopic cylinder 31 is provided with two groups, one of which is connected to the top surface of the die 11, and the end of the telescopic cylinder 31 is connected to the first pressing plate 32. The other group of telescopic cylinders 31 is connected to the top surface of the die base 13, and the end of the telescopic cylinder 31 connected to the top surface of the die base 13 is connected to the second pressing plate 33. The die 11 and the die base 13 are close to each other, which drives the first pressing plate 32 and the second pressing plate 33 to approach each other. The first pressing plate 32 and the second pressing plate 33 are used to clamp and fix the stamping plate 16. One side of the stamping plate 16 is attached to the die 11, and the other side It is adhered to the second pressing plate 33, and one side of the second pressing plate 33 is connected to a guide groove 34, and a connecting block 35 is provided inside the guide groove 34. In the fixation of the stamping plate 16, the stamping plate 16 is embedded between the first pressing plate 32 and the second pressing plate 33, and the first pressing plate 32 and the second pressing plate 33 are continuously approached by the expansion of the telescopic cylinder 31, thereby limiting the position of the stamping plate 16. After the stamping plate 16 is fixed, one side of the stamping plate 16 can also be adhered to the surface of the die 11, and the stamping plate 16 is supported by the die 11. When the punch 15 hits the surface of the stamping plate 16, the stamping plate 16 is shaped.

[0025] During the stamping process, in order to prevent the punch 15 from initially contacting the stamping plate 16 and causing local warping of the stamping plate 16, the die plate 42 can be directly used to clamp the stamping plate 16, thereby limiting the warping of the stamping plate 16. The specific operation is as follows: The interior of the connecting block 35 is embedded with a die assembly 4, and the die assembly 4 includes a suspension rod 41, the bottom end of the suspension rod 41 is connected to a die plate 42, the inner wall of the die plate 42 is filled with a magnet, and the die plate 42 is adsorbed on one side of the stamping plate 16 by the magnet, and the die plate 42 slides inside the guide groove 34 through the suspension rod 41. A limiting device is provided on the suspension rod 41, and the limiting device can limit the position of the suspension rod 41 in the guide groove 34. An oil tank 46 is provided inside the die plate 42, and the oil tank 46 is evenly distributed inside the die plate 42. The interior of the oil tank 46 is filled with lubricating liquid, and the top of the die plate 42 is connected to a cover plate 43, and the cover plate 43 is used to cover the top of the oil tank 46 The cover plate 43 and the pressing plate 42 are slidably connected, and a reset structure is provided at the connection, which is used to cover the cover plate 43 on the top opening of the oil tank 46. The top of the punch 15 is connected with a push plate 44, and a through groove 45 is provided on the die base 13. The push plate 44 is used to push the cover plate 43 out of the top opening of the oil tank 46. The pressing plate 42 is between the punch 15 and the stamping plate 16, so the suspension rod 41 is connected to the inside of the guide groove 34 for horizontal sliding. The die 11 and the punch 15 are matched, and the punch 15 is used to stamp the stamping plate 16. During the stamping process, the punch 15 passes through the through hole opened on the surface of the pressing plate 42 until it passes through the stamping plate 16 until it fits with the die 11.

[0026] During the stamping process, the die and the surface of the stamped part are in direct contact and produce relative motion, which will generate a large friction force. The lubricating liquid stored in the oil tank 46 can flow out to form a lubricating film between the punch 15 and the stamping plate 16, separating the surface of the die and the stamped part, avoiding direct contact, thereby significantly reducing the friction force. In addition, during the process of the punch 15 applying pressure to the stamping plate 16 for stamping, the stamping plate 16 will be subjected to a strong impact force, which is prone to local warping or displacement. The adsorption force of the magnet can effectively enhance the restraining effect of the die plate 42 on the stamping plate 16, so that the stamping plate 16 always maintains a stable state during the stamping process. This stable constraint helps to suppress the deformation of the stamping plate 16, making the stamping plate 16 smoother after stamping, and greatly reducing the damage to the internal structure. The magnet adsorption can ensure the position accuracy of the stamping plate 16 at the microscopic level, avoiding it from slight displacement before stamping, thereby ensuring that the starting position of the stamping is accurate.

[0027] During stamping, the stamping plate 16 is first embedded between the die 11 and the punch 15, and one side of the stamping plate 16 is tightly fitted to the surface of the die 11. Then, the pressing plate 42 is pushed so that the suspension rod 41 at the top of the pressing plate 42 slides inside the guide groove 34. The pressing plate 42 is fitted to the other side of the stamping plate 16 by sliding. After it is fully fitted, the position of the suspension rod 41 is limited by the limiting device, wherein the limiting device is composed of an insert rod and a pin. By inserting the insert rod into the corresponding pin, the position of the suspension rod 41 is limited. At this time, both sides of the stamping plate 16 are restricted. Constraint, then the punch 15 and the guide plate 14 slide relative to each other, the punch 15 can be pushed by the hydraulic rod, so that the punch 15 passes through the inside of the die base 13 and gradually approaches the die plate 42. When the punch 15 and the die plate 42 are in contact, the punch 15 continues to push, and the punch 15 will be embedded in the inside of the die plate 42 until it completely passes through the die plate 42. At this time, the punch 15 will be pressed onto the surface of the stamping plate 16, and then the force of the punch 15 on the stamping plate 16 causes the stamping plate 16 to deform. Finally, the punch 15 cuts the stamping plate 16, and the punch 15 is embedded in the inside of the die 11 to complete the stamping. During this stamping process, a through hole matching the stamping part is set through the pressing plate 42, so that the punch 15 can pass through the interior of the pressing plate 42, thereby completing the stamping of the stamping plate 16. During this period, when the punch 15 just contacts the stamping plate 16, the deformation of the stamping plate 16 caused by the applied force will also be suppressed under the constraint of the pressing plate 42, thereby suppressing the deformation of the stamping plate 16. This stamping method makes the stamping plate 16 smoother after stamping, and can also reduce the internal structural damage of the stamping plate 16 caused by excessive deformation, and stabilize the structure of the formed part after stamping.

[0028] The upper surface of the guide plate 14 is also connected to a photoelectric component 2, which includes a supporting column 21, a guide rod 22 embedded inside the supporting column 21, and a parallel lamp 23 connected to the bottom end of the guide rod 22. The parallel lamp 23 is suspended at the bottom end of the supporting column 21 through the guide rod 22. The parallel lamp 23 is arranged between the mold base 13 and the guide plate 14. The parallel lamp 23 slides inside the supporting column 21 through the guide rod 22 to achieve longitudinal movement. The parallel lamp 23 emits parallel light, and the parallel light passes through the mold base 13 and shines on the pressing plate 42. The projection generated by the parallel light shining on the pressing plate 42 is projected onto the stamping plate 16. A photoelectric sensor transmitting end and a receiving end are installed inside the parallel lamp 23. The photoelectric sensor transmitter emits a light signal, which is reflected after contacting the stamping plate 16 and is finally received by the photoelectric sensor receiving end.

[0029] In addition, during stamping, some of the plates to be stamped may have local defects due to improper placement. In order to avoid this problem, when the stamping plate 16 is embedded between the die 11 and the punch 15, the stamping plate 16 is clamped by the first pressing plate 32 and the second pressing plate 33. Then the descent of the guide rod 22 drives the descent of the parallel lamp 23. When the parallel lamp 23 descends until it corresponds to the opening of the die base 13, the parallel lamp 23 is lit. After being lit, the parallel lamp 23 emits parallel light, and then this parallel light passes through the interior of the die base 13 and illuminates the die. On the plate 42, the parallel light irradiated on the stamping template 42 will project a projection, and a signal will be sent out through the transmitting end of the photoelectric sensor inside the parallel lamp 23, and the transmitted signal will be received after being reflected by the stamping plate 16, so as to judge whether the projection can completely fall into the surface of the stamping plate 16. When the projection completely falls into the surface of the projection, the problem of missing corners can be avoided as the punch 15 is stamped, thereby reducing the problem of stamping defects. When the projection cannot completely fall on the stamping plate 16, the position of the stamping plate 16 is manually adjusted to improve the pass rate.

[0030] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
