Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, and in particular relates to a stamping equipment for automotive parts processing. Background Technology

[0002] Automotive parts stamping equipment is a specialized mechanical device used to apply external force to metal sheets through pressure and dies, causing them to undergo plastic deformation or separation. The stamping equipment places steel, sheet metal or steel strip on the stamping die, and the stamping device above applies pressure to the steel through the stamping head, causing it to undergo plastic deformation or separation, thereby obtaining automotive parts of the required shape and size.

[0003] In the prior art, Chinese utility model patent CN222036528U discloses a stamping device for automotive parts, relating to the field of automotive parts processing technology. It solves the technical problem of inconvenient stamping head replacement due to the lack of a mechanism connecting the stamping head and the stamping cylinder, which makes stamping head replacement inconvenient after changing the stamping die. The device includes a worktable with an L-shaped side plate mounted at its center. A circular top plate is connected to the horizontal end of the side plate, and a stamping cylinder is fixedly inserted at its center. A connecting assembly is connected to the lower end of the stamping cylinder. A mounting hole is provided on the upper surface of the worktable, and the stamping die is slidably fitted into the mounting hole. This utility model, through the setting of the connecting assembly, facilitates the replacement of the stamping head and effectively limits its movement after replacement.

[0004] In existing technologies, the connection components facilitate the replacement of the stamping head, improving the practicality of the device. However, there are still some shortcomings in overall use:

[0005] First, after the sheet metal is stamped, the sheet metal parts need to be manually removed from the mold, which is a cumbersome operation. At the same time, some parts will get stuck inside the mold and are extremely difficult to remove, which is time-consuming, laborious, and inefficient. Since the edges of the stamped parts will have burrs, manual unloading can also cause the parts to cut the workers, posing a significant safety hazard.

[0006] Secondly, the existing stamping devices do not have the effect of limiting the stamping head, and the positioning effect of the stamping head is poor, which makes it easy to cause stamping misalignment when the mold is closed. In the high-speed stamping process, even a small misalignment can lead to deviation in part specifications and reduce product quality. In more serious cases, a large misalignment can also cause damage to the mold. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, this invention provides a stamping device for processing automotive parts. This invention solves the technical problems of low work efficiency and the risk of worker injury caused by manual unloading of sheet metal after stamping. Furthermore, it addresses the issue of misalignment of stamping dies leading to reduced product quality.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a stamping equipment for processing automotive parts, comprising a base, a material feeding groove in the middle of the base, a stamping head slidably mounted above the material feeding groove, two symmetrically arranged molds slidably mounted on the upper surface of the base, the molds being drivenly connected to the stamping head, an embedding groove being formed inside the two molds, a push rod being slidably mounted inside the embedding groove, a push plate adapted to the embedding groove being fixedly mounted at one end of the push rod inside the mold for ejecting the stamped part, a fixing block being fixedly mounted at one end of the push rod outside the mold, a first spring being fixedly mounted between the side of the fixing block and the outer side of the mold through which the push rod passes, and downwardly inclined through holes being formed on the opposite surfaces of the two push plates.

[0009] In a stamping machine used for processing automotive parts, two symmetrically arranged grooves are formed on the upper surface of the base. A lead screw is rotatably installed inside the groove. The die is threadedly engaged with the surface of the lead screw and slides inside the groove.

[0010] In a stamping machine used for processing automotive parts, a column is fixedly installed on the upper surface of the base, a top plate is fixedly installed on the upper surface of the column, a hydraulic cylinder is fixedly installed on the top of the top plate, a limit plate is fixedly installed at the output end of the hydraulic cylinder, and the lower surface of the limit plate is fixed to the upper surface of the stamping head.

[0011] In a stamping equipment used for processing automotive parts, air pumps are fixedly installed on both sides of the base, the air outlet of the air pumps is connected to a duct, the push plate is hollow, and the push plate is connected to the duct.

[0012] In stamping equipment used for processing automotive parts, the end of the conduit near the air pump is a telescopic tube, and the section inside the mold is a straight tube.

[0013] In a stamping machine used for processing automotive parts, four rectangular limiting posts are fixedly installed on the upper surface of the base, and the top of the limiting posts slides through the upper surface of the limiting plate.

[0014] In a stamping machine used for processing automotive parts, a second spring is fitted at the bottom of the limiting post.

[0015] In a stamping machine used for processing automotive parts, the die is located on both sides of the blanking trough, and a collection box is provided below the blanking trough, with a screen fixedly installed inside the collection box.

[0016] In summary, compared with the prior art, the stamping equipment for processing automotive parts provided by this utility model has the following beneficial effects:

[0017] 1. This utility model, through the design of molds, push plates, and through holes, can automatically position and fix the sheet metal during stamping, eliminating the need for manual positioning, ensuring stamping accuracy, and greatly improving work efficiency. After stamping, it can also automatically open the mold, push out the finished parts, and blow away the waste, preventing residual waste from accumulating on the inner surface of the mold and causing unevenness in subsequent stamped parts, thus improving the performance. At the same time, it eliminates the need for manual material unloading, speeding up work efficiency.

[0018] 2. This utility model, through the setting of a limiting plate, a limiting post, and a second spring, can limit the stamping head, ensuring the accuracy of stamping and preventing misalignment of the stamping head. At the same time, it can reduce vibration during stamping, ensuring that vibration and deviation do not occur at the moment the stamping head contacts the sheet metal, thus greatly improving product quality.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1:

[0026] refer to Figure 1 A stamping device for processing automotive parts includes a base 10, with a support leg 11 fixedly installed on the lower surface of the base 10, a controller 12 provided on the front surface of the base 10 for controlling the electrical equipment in the device, a feeding groove 13 opened in the middle of the base 10 for discharging the parts after stamping, and a collection box 14 provided below the feeding groove 13 for collecting the discharged parts.

[0027] Further reference Figure 1 A column 15 is fixedly installed on the upper surface of the base 10. A top plate 16 is fixedly installed on the top of the column 15. A hydraulic cylinder 17 is fixedly installed on the top of the top plate 16. The output end of the hydraulic cylinder 17 slides through and a limit plate 18 is fixedly installed at the end. A punching head 19 is fixedly installed on the lower surface of the limit plate 18. In use, the controller 12 controls the hydraulic cylinder 17 to work, so that the hydraulic cylinder 17 drives the limit plate 18 and the punching head 19 to move downward, and punch the sheet metal to obtain automotive parts of the required shape and size.

[0028] Further reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The upper surface of the base 10 has two symmetrically arranged sliding grooves 20. A lead screw 21 is rotatably installed inside the two sliding grooves 20. The surface of the lead screw 21 is threaded with a mold 23 that slides inside the sliding groove 20. Servo motors 22 that drive the lead screw 21 are fixedly installed on both sides of the base 10. In use, the operator places the workpiece between the two molds 23. When stamping, the servo motor 22 rotates clockwise, driving the lead screw 21 connected to it to rotate. While the lead screw 21 rotates, the mold 23 is limited by the sliding groove 20, so that the threaded mold 23 can slide in the center inside the sliding groove 20, thereby centering and clamping the sheet metal. There is no need for manual positioning by the operator, which not only speeds up the work efficiency but also reduces safety hazards.

[0029] It should be noted that the stamping head 19 and the mold 23 in the attached drawings can be customized according to the actual production situation, and are not limited to the shapes shown in the attached drawings. They are existing technologies and will not be described in detail in this solution.

[0030] Further reference Figure 1 , Figure 3 and Figure 4The mold 23 has an internal embedding groove 27. A push rod 24 is slidably installed inside the embedding groove 27. A push plate 28 is fixedly installed at one end of the push rod 24 inside the mold 23. The push plate 28 is adapted to the embedding groove 27. A fixing block 25 is fixedly installed at the outer end of the push rod 24 outside the mold 23. A first spring 26, which is penetrated by the push rod 24, is fixedly installed between one side of the fixing block 25 and the outer side of the mold 23. When the sheet metal is placed between the two molds 23 for stamping, the two molds 23 are aligned and clamp and position the sheet metal. At this time, the sheet metal will push the push plate 28 outward, causing the first spring 26 to elastically deform and stretch until the push plate 28 is pressed into the embedding groove 27, thus completing the clamping and limiting of the sheet metal. After stamping is completed, the same The servo motor 22 rotates counterclockwise, causing the two molds 23 to separate to the sides, making it easier for the part to be removed from the molds 23. At this time, the pressure of the first spring 26 disappears, causing the first spring 26 to contract and reset, thereby resetting the push rod 24. The push plate 28 connected to it is then reset, pushing the part outward until the part leaves one of the molds 23 and falls into the feeding trough 13 for collection by the collection box 14. The push plate 28 is designed to push the part out, preventing it from sticking to one of the molds 23 and falling into the feeding trough 13. It can automatically push out and collect the formed part without the need for manual feeding by the operator, greatly speeding up the work efficiency and preventing the operator from being accidentally injured by end face burrs, thus greatly improving safety.

[0031] It should be noted that the embedding groove 27 and push plate 28 in the attached drawings can be customized according to actual production conditions and are not limited to the shapes shown in the attached drawings. They are existing technologies and will not be described in detail in this solution.

[0032] Further reference Figure 3 and Figure 4 The push plate 28 is hollow, and its opposite side has a downwardly inclined through hole 29. Air pumps 30 are fixedly installed on both sides of the base 10. The air outlet of the air pump 30 is connected to a duct 31. The end of the duct 31 near the air pump is a telescopic tube, and the end inside the mold 23 is a straight tube. The duct 31 is connected to the push plate 28. After stamping, when the push plate 28 pushes out the part, the air pump 30 works, sending gas into the push plate 28 through the duct 31 and spraying it out through the through hole 29. Since the through hole 29 is downwardly inclined, the sprayed gas sprays onto the lower surface of the mold. With the push plate 28 moving forward, the residual debris in the mold can be blown into the collection box 14, avoiding the accumulation of debris on the surface of the mold 23, which would cause unevenness on the surface of the stamped part and improve the stamping effect.

[0033] Furthermore, refer to Figure 4The collection box 14 is equipped with a screen 34, which is used to trap the parts on its surface when collecting parts, so that the stamping waste continues to fall below for collection. Because the falling parts have impact force, the parts impact the screen 34, causing the screen 34 to vibrate under pressure, which facilitates the falling of waste. Example 2:

[0034] A stamping equipment for processing automotive parts, further illustrated in Embodiment 1, is provided with reference to [reference needed]. Figure 1 Four rectangular limiting posts 32 are fixedly installed on the upper surface of the base 10. The limiting posts 32 slide through the upper surface of the limiting plate 18, and a second spring 33 is sleeved on the lower part of the limiting posts 32. When the sheet metal is stamped, the limiting plate 18 moves downward under the guidance of the limiting posts 32 and compresses the second spring 33. This can ensure the stability of the stamping head 19 when it moves downward to stamp, prevent misalignment during high-speed stamping, and at the same time, the second spring 33 can provide shock absorption to ensure that vibration and displacement are avoided at the moment the stamping head contacts the sheet metal, thereby improving product quality.

[0035] It should be noted that the second spring 33 is made of a damping material that absorbs energy and reduces vibration when compressed, and does not exhibit a rebound phenomenon. This is existing technology and will not be described in detail in this solution.
