The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0037] An embodiment of the present application provides a hot forming punching device for automotive part production. The schematic diagram of the hot forming punching device for automotive part production is as Figures 1-6 shown. The hot forming punching device for automotive part production includes a workbench 10. At multiple top corners on the upper surface of the workbench 10, there are connecting top columns 20. The tops of the multiple top columns 20 are connected to a top plate 30. On the plate body of the top plate 30, there is a punching mechanism 40 connected.

[0038] The punching mechanism 40 includes a cylinder 41 connected to the upper surface of the plate body of the top plate 30, a lifting plate 42 connected to the execution end of the cylinder 41, and a punching tool 43 connected to the lifting plate 42. On the lower surface of the plate body of the lifting plate 42, there is a shielding assembly 44 connected.

[0039] The shielding assembly 44 includes a plurality of telescopic rods 441 connected to the lower surface of the lifting plate 42. The plurality of telescopic rods 441 are arranged around the punching tool 43. At the bottom end of the rod body of the telescopic rod 441, there is a brush 442 connected.

[0040] It should be noted that in this embodiment, the stable framework constructed by the top columns 20 and the top plate 30 provides a reliable installation foundation for the punching mechanism 40. The lifting plate 42 driven by the cylinder 41 realizes precise lifting control of the punching tool 43. The setting of the shielding assembly 44 effectively blocks the splashing of debris during punching, protects the working environment, and at the same time, the brush 442 can clean the impurities on the surface of the parts to a certain extent, improving the product quality.

[0041] Optionally, please refer to the attached Figure 5 and 6 . The punching tool 43 includes a chassis 431 connected to the upper surface of the plate body of the lifting plate 42. The upper surface of the chassis 431 is connected to the execution end of the cylinder 41. Inside the chassis 431, there is a motor 432 connected to the upper surface of the top plate 30. The execution end of the motor 432 is connected to a punching head 433.

[0042] In this embodiment, the chassis 431 moves along with the lifting plate 42, and the motor 432 is fixed on the upper surface of the top plate 30 and located inside the chassis 431. After the motor 432 is powered on and operates, its execution end drives the punching head 433 to rotate at a high speed. When the cylinder 41 pushes the lifting plate 42 to descend, the rotating punching head 433 performs punching operations on the components. The above structural design enables the motor 432 to stably provide power for the punching head 433, and the punching head 433 rotating at a high speed can efficiently complete the punching operation, ensuring the punching efficiency and quality. At the same time, the chassis 431 plays a certain protective role for the motor 432, extending the service life of the motor.

[0043] Optionally, please refer to the attached Figure 2 and 3 , the telescopic rod 441 includes a guide rod 4411 connected to the lower surface of the lifting plate 42 and a sliding outer rod 4412 slidably connected to the outer surface of the rod body of the guide rod 4411, and adjacent sliding outer rods 4412 abut against each other;

[0044] A spring 4414 is sleeved on the outer surface of the guide rod 4411. One end of the spring 4414 abuts against the outer surface of one end of the sliding outer rod 4412, and the other end of the spring 4414 abuts against the lower surface of the lifting plate 42.

[0045] In this embodiment, during the descent of the lifting plate 42, the guide rod 4411 moves downward along with the lifting plate 42, and the sliding outer rod 4412 slides downward on the guide rod 4411. Since adjacent sliding outer rods 4412 abut against each other, they jointly form a relatively tight shielding structure. The spring 4414 is compressed during this process. When it comes into contact with the surface of the component, the elastic force of the spring 4414 enables the telescopic rod 441 to adapt to the thickness change of the component. This structural design of the telescopic rod 441 gives it good flexibility and adaptability, enabling it to closely fit the surfaces of components with different thicknesses, enhancing the shielding effect of the shielding assembly 44, and effectively preventing debris from splashing out through the gaps between the telescopic rods 441. At the same time, the buffering effect of the spring 4414 can prevent the brush 442 from exerting excessive pressure on the surface of the component and damaging the component.

[0046] Optionally, please refer to the attached Figure 3 and 4 , a retaining ring 4413 is connected to the outer surface of one end of the guide rod 4411 extending into the sliding outer rod 4412, and the retaining ring 4413 is slidably connected to the inner wall surface of the sliding outer rod 4412.

[0047] In this embodiment, during the telescopic process of the telescopic rod 441, the guide rod 4411 slides within the sliding outer rod 4412, and the anti - detachment ring 4413 moves together with the guide rod 4411, always contacting the inner wall of the sliding outer rod 4412, restricting the sliding range of the sliding outer rod 4412 on the guide rod 4411 and preventing it from falling off the guide rod 4411. The design of the anti - detachment ring 4413 greatly improves the structural stability and reliability of the telescopic rod 441, ensures that the shielding assembly 44 can work properly during long - term use, avoids the failure of the shielding function caused by the detachment of the sliding outer rod 4412, and guarantees the continuity and safety of the device operation.

[0048] Optionally, please refer to the appendix Figure 5 and 6 , a chip suction head 421 is embedded in the plate body of the lifting plate 42. The chip suction head 421 is located between multiple guide rods 4411, and the inner cavity of the chip suction head 421 is connected to the dust suction fan 422 through a hose.

[0049] In this embodiment, when the punching operation is carried out, the dust suction fan 422 is started, creating a negative pressure in the inner cavity of the chip suction head 421. Since the chip suction head 421 is embedded in the lifting plate 42 and located between multiple guide rods 4411, the chips generated by punching are sucked into the chip suction head 421 under the action of the negative pressure, and then are transported to the dust suction fan 422 through the hose connected to the inner cavity of the chip suction head 421 for collection. The chip suction device can timely and effectively suck the chips generated during the punching process, further reducing the splashing of chips in the working environment, significantly improving the cleanliness of the working environment, and at the same time reducing the wear risk of the chips to the running parts of the equipment, improving the service life of the equipment and the product quality.

[0050] Optionally, please refer to the appendix Figure 4 and 5 , the chip suction head 421 is a ring - shaped hollow structure, and a plurality of dust suction ports 423 are provided on the lower surface of the chip suction head 421. The middle hole of the ring - shaped chip suction head 421 is used for the punching head 433 to pass through.

[0051] In this embodiment, the ring - shaped hollow structure of the chip suction head 421 and the plurality of dust suction ports 423 on its lower surface work together to expand the chip suction range. Under the negative pressure generated by the dust suction fan 422, the chips are sucked into the chip suction head 421 from each dust suction port 423. The middle hole of the ring - shaped chip suction head 421 allows the punching head 433 to pass through, enabling the chip suction head 421 to perform dust suction operations on the area where chips are generated at a close distance when the punching head 433 is working. The above - mentioned structural design enables the chip suction head 421 to absorb the chips generated by punching more comprehensively and efficiently, improves the dust suction efficiency, ensures the timely cleaning of chips in the working area, and provides a cleaner and safer working environment for the punching operation.

[0052] Optionally, please refer to the appendixFigure 4 The lower surface of the chip suction head 421 is connected with a guiding ring 424, and the guiding ring 424 can be abutted against the outer surface of the sliding outer rod 4412.

[0053] In this embodiment, during the descending process of the telescopic rod 441, the guiding ring 424 descends together with the chip suction head 421. When the guiding ring 424 contacts the outer surface of the sliding outer rod 4412, it plays a guiding role for the sliding outer rod 4412, making the sliding of the sliding outer rod 4412 on the guiding rod 4411 more stable. At the same time, the guiding ring 424 also enhances the connection stability between the chip suction head 421 and the telescopic rod 441. The setting of the guiding ring 424 improves the stability of the telescopic rod 441 during the telescopic process, reduces the sway of the sliding outer rod 4412, so that the shielding assembly 44 can better play the shielding role, and at the same time ensures the position accuracy of the chip suction head 421 during the working process, improving the chip suction effect.

[0054] Optionally, please refer to the attached Figure 4 and 5 , the ring height of the guiding ring 424 is greater than the length of the guiding rod 4411.

[0055] In this embodiment, since the ring height of the guiding ring 424 is greater than the length of the guiding rod 4411, during the entire telescopic stroke of the telescopic rod 441, the guiding ring 424 can always contact the sliding outer rod 4412 and play a guiding role. Whether the telescopic rod 441 is in the extended state or the retracted state, the guiding ring 424 can provide stable guiding support for the sliding outer rod 4412.

[0056] Based on the same inventive concept, this embodiment also provides a hot forming punching method for automobile part production, including the following steps:

[0057] Step 1, placing the automobile part to be punched on the workbench 10;

[0058] Step 2, starting the air cylinder 41, so that the execution end of the air cylinder 41 pushes the lifting plate 42 to descend, driving the shielding assembly 44 and the punching device 43 to descend together;

[0059] Step 3, during the descending process of the shielding assembly 44, the telescopic rod 441 extends, so that the brush 442 contacts the surface of the part;

[0060] Step 4, starting the motor 432, and the motor 432 drives the punching head 433 to rotate at a high speed to perform a punching operation on the punching position.

[0061] Optionally, please refer to the attached drawings. At the same time as step 4, start the dust suction fan 422, and suck away the chips generated by punching through the chip suction head 421.

[0062] The specific operation mode of the present invention is as follows:

[0063] When using the punching device for thermoformed automotive parts, first place the workbench 10 on a stable working site, install the ejector pin 20 and the top plate 30, and ensure the stability of the frame structure. Then install the punching mechanism 40, firmly install components such as the cylinder 41 and the punch 43, and connect the circuits and air paths between the components.

[0064] Install and debug the shielding assembly 44 to ensure that the telescopic rod 441 can extend and retract normally and the position of the brush 442 is appropriate. Install the chip suction device, connect the hose between the chip suction head 421 and the dust suction fan 422, and debug the dust suction effect.

[0065] Place the automotive part to be punched on the workbench 10, start the cylinder 41, and the cylinder 41 drives the lifting plate 42 to descend. At this time, the telescopic rod 441 of the shielding assembly 44 descends with the lifting plate 42, and the brush 442 contacts the surface of the part, playing a role in shielding debris. At the same time, the motor 432 starts, driving the punch head 433 to rotate at high speed to perform a punching operation on the punching position. During the punching process, the dust suction fan 422 sucks away the generated debris through the chip suction head 421 to keep the working environment clean.

[0066] The above has made an exemplary description of the present invention in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as this non-substantial improvement is made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
