Description

Technical Field

[0001] This utility model relates to the technical field of automotive molds, and in particular to a protective mechanism for stamped parts in automotive manufacturing. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube and profile, causing plastic deformation or separation, thereby obtaining a workpiece with the required shape and size. Automotive stamping parts, as the name suggests, are metal stamping parts that make up automotive components, and they all need to be stamped by a stamping machine during the manufacturing process.

[0003] During the stamping operation, workers are prone to losing focus due to prolonged monotonous and repetitive operations. Because the pressure generated by the stamping machine is extremely high during stamping, if workers lose focus, it can lead to serious work-related accidents, posing a significant safety hazard to both the company and the workers. Therefore, it is necessary to provide a stamping part protection device during the stamping process.

[0004] An existing patent (publication number: CN211866435U) discloses a protective device for stamping parts in automobile manufacturing. This utility model effectively prevents workers from stepping on the power pedal due to lack of concentration during long-term monotonous operation, resulting in failure to complete material changing or cleaning, thus causing serious work-related accidents.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, during the stamping process of existing automotive stamping parts, the lower die of the stamping machine bears the stamping parts for an extended period of time. As a result, particles or impurities that are detached from the stamping parts fall onto the surface of the lower die. Due to the lack of an effective protective and cleaning mechanism, these residual particles and impurities will cause uneven pits to form on the surface of the stamped parts in subsequent stamping processes, seriously affecting the quality of automotive stamping parts.

[0006] Therefore, a protective mechanism for stamped parts in automobile manufacturing is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a protective mechanism for stamped parts in automobile manufacturing. This mechanism can solve the problem that during the stamping process of existing automobile stamped parts, particles or impurities that fall off the stamped parts due to the long-term bearing of the stamped parts by the lower die of the stamping machine will fall onto the surface of the lower die. Due to the lack of an effective protective and cleaning mechanism, these residual particles and impurities will cause uneven pits to form on the surface of the stamped parts in subsequent stamping processes, which seriously affects the quality of automobile stamped parts.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a protective mechanism for stamped parts in automobile manufacturing, including a stamping table, a lower mold provided on the top of the stamping table, uprights provided at the four corners of the top of the stamping table, a stamping structure provided on the top of the uprights, and a protective cleaning mechanism provided between the stamping structure and the stamping table.

[0009] The protective cleaning mechanism includes a cavity formed on the front side of the top of the stamping table. A fan is installed on the bottom side inside the stamping table, and the output end of the fan is connected to an elastic tube. The top of the elastic tube passes through the top side of the stamping table and extends into the cavity. Telescopic spring columns are installed on both sides inside the cavity. A multi-hole nozzle is bolted to the top of the telescopic spring column. The bottom of the multi-hole nozzle is connected to the bottom of the elastic tube. A touch sensor is installed on the top of the multi-hole nozzle. An automatic controller is bolted to the left side of the stamping table. A touch-proof structure is installed on the top of the cavity, and the touch-proof structure is located at the bottom of the stamping structure.

[0010] Preferably, the touch-resistant structure includes a protective frame disposed on the front side of the bottom of the stamping structure, the protective frame being located at the top of the cavity.

[0011] Preferably, the protective frame has a transparent panel inside, which is made of tempered glass.

[0012] Preferably, a touch rod is bolted to the bottom of the protective frame, and the touch rod is located on top of the touch sensor.

[0013] Preferably, the stamping structure includes a fixing plate fixedly connected to the top of the upright, and a hydraulic cylinder is bolted to the top of the fixing plate, with the telescopic end of the hydraulic cylinder penetrating through the top of the fixing plate.

[0014] Preferably, the extension end of the hydraulic cylinder is bolted with a lifting plate, the front side of the lifting plate is bolted to the rear side of the protective frame, the lifting plate is slidably connected to the outside of the upright, and an upper mold is provided at the bottom of the lifting plate.

[0015] Preferably, a collection groove is provided on the rear side of the top of the stamping table, and a collection box is provided inside the collection groove.

[0016] Preferably, transparent acrylic sheets are bolted to both sides of the lifting plate, and docking grooves are provided on both sides of the top of the stamping table, with the docking grooves located at the bottom of the transparent acrylic sheets.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up a protective cleaning mechanism, before the automotive stamping part is placed on top of the lower die for stamping, a blower delivers gas through an elastic tube to a multi-hole nozzle. At this time, the multi-hole nozzle effectively blows away particles and impurities remaining on the surface of the lower die, preventing damage to subsequent stamping parts. This greatly improves the surface smoothness and overall quality of the automotive stamping parts, ensuring production stability and product consistency. Then, the automotive stamping part is placed on top of the lower die. At this point, the stamping structure drives the anti-touch structure downwards, and the anti-touch structure contacts and triggers the touch sensor. After receiving the signal, the controller shuts off the fan, and the multi-hole nozzle, after being squeezed, compresses the telescopic spring column downward, thus hiding the multi-hole nozzle inside the cavity. At the same time, the anti-touch structure is also located on the front side of the lower mold and the stamping structure, further protecting the stamped parts during stamping. Conversely, after the stamping is completed, the stamping structure drives the anti-touch structure back to its initial position, and then the anti-touch structure disengages from the contact sensor. After feedback to the controller, the fan is started, and the telescopic spring column disengages from the compression and ejects the multi-hole nozzle to blow away and clean the particles and impurities remaining on the surface of the lower mold.

[0019] 2. By setting up a stamping structure, this application can accurately apply appropriate pressure to automotive stamping parts. Combined with a protective cleaning mechanism, it can ensure the stamping effect while further reducing the probability of stamping failure or defective products caused by impurities, thereby improving production efficiency, reducing production costs, and providing a strong guarantee for efficient and high-quality production in the automotive manufacturing industry.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A protective mechanism for stamped parts in automobile manufacturing includes a stamping table 1, a lower mold 2 on the top of the stamping table 1, uprights 3 at the four corners of the top of the stamping table 1, a stamping structure 4 on the top of the uprights 3, and a protective cleaning mechanism 5 between the stamping structure 4 and the stamping table 1.

[0029] The protective cleaning mechanism 5 includes a cavity 51 located on the front side of the top of the stamping table 1. A fan 52 is installed on the bottom side inside the stamping table 1. The output end of the fan 52 is connected to an elastic tube 53. The top of the elastic tube 53 passes through the top side of the stamping table 1 and extends into the cavity 51. Telescopic spring columns 54 are installed on both sides inside the cavity 51. A multi-hole nozzle 55 is bolted to the top of the telescopic spring column 54. The bottom of the multi-hole nozzle 55 is connected to the bottom of the elastic tube 53. A touch sensor 56 is installed on the top of the multi-hole nozzle 55. An automatic controller 57 is bolted to the left side of the stamping table 1. A touch-proof structure 58 is installed on the top of the cavity 51. The touch-proof structure 58 is located at the bottom of the stamping structure 4.

[0030] In this embodiment: by setting a stamping structure 4 and a protective cleaning mechanism 5, the stamping structure 4 is used to apply pressure to the automotive stamping part placed on the lower mold 2 to realize the stamping forming operation. Before each stamping, the fan 52 of the protective cleaning mechanism 5 is in working condition, and the gas is delivered to the multi-hole nozzle 55 through the elastic tube 53. The multi-hole nozzle 55 sprays airflow onto the surface of the lower mold 2 to remove particles and impurities remaining on the surface of the lower mold 2, ensuring a clean stamping environment. When the stamping structure 4 moves downward, the contact-resistant structure 58 moves downward accordingly. Once the contact-resistant structure 58 touches the touch sensor 56, the touch sensor 56 immediately transmits a signal to the automatic controller 57. 7. The control fan 52 is turned off, and the stamping structure 4 continues to descend for stamping. At this time, the telescopic spring column 54 is compressed by the multi-hole nozzle 55, causing the multi-hole nozzle 55 to be hidden in the cavity 51. Meanwhile, the anti-contact structure 58 is located on the front side of the stamping area to play a protective role, preventing foreign objects from entering the key stamping parts. After stamping is completed, the stamping structure 4 rises and resets, and the anti-contact structure 58 rises and disengages from the touch sensor 56. The automatic controller 57 restarts the fan 52, and the telescopic spring column 54 extends and pushes out the multi-hole nozzle 55 to continue cleaning the surface of the lower mold 2 in preparation for the next stamping. This cycle effectively ensures the quality of the stamped parts and the stability of production.

[0031] Specifically, such as Figure 3 As shown, the touch protection structure 58 includes a protective frame 581 disposed on the front side of the bottom of the stamping structure 4, and the protective frame 581 is located on the top of the cavity 51.

[0032] Specifically, such as Figure 3 As shown, a transparent plate 82 is provided inside the protective frame 581, and the transparent plate 82 is made of tempered glass.

[0033] Specifically, such as Figure 3 As shown, a touch rod 583 is bolted to the bottom of the protective frame 581, and the touch rod 583 is located on top of the touch sensor 56.

[0034] In this embodiment: by setting the touch protection structure 58, during the stamping process, the protective frame 581 moves synchronously with the stamping structure 4. When the stamping starts, the touch rod 583 at the bottom of the protective frame 581 first contacts the touch sensor 56 and feeds back to the automatic controller 57. The automatic controller 57 controls the fan 52 to stop working and simultaneously squeezes the multi-hole nozzle 55 into the cavity 51 for concealment, ensuring that the lower mold 2 area is ready for stamping. At the same time, the tempered glass transparent plate 82 inside can protect the operator from observing the stamping area while avoiding interference with the stamping process. This ensures that the automotive stamping parts are formed in a relatively clean and safe environment, reduces defective products caused by foreign objects, and improves production quality.

[0035] Specifically, such as Figure 3As shown, the stamping structure 4 includes a fixing plate 41 fixedly connected to the top of the upright 3. A hydraulic cylinder 42 is bolted to the top of the fixing plate 41, and the telescopic end of the hydraulic cylinder 42 passes through the top of the fixing plate 41.

[0036] Specifically, such as Figure 3 As shown, the extension end of the hydraulic cylinder 42 is bolted with a lifting plate 43. The front side of the lifting plate 43 is bolted to the rear side of the protective frame 581. The lifting plate 43 is slidably connected to the outside of the upright 3. An upper mold 44 is provided at the bottom of the lifting plate 43.

[0037] In this embodiment: by setting up a stamping structure 4, the hydraulic cylinder 42 receives power from the power source and its telescopic end drives the lifting plate 43 to slide up and down along the upright 3. When stamping is required, the hydraulic cylinder 42 pushes the lifting plate 43 down, so that the upper mold 44 at the bottom closes with the lower mold 2, and applies sufficient pressure to the automotive stamping part placed on the lower mold 2, so that it undergoes plastic deformation to achieve the required shape. This structural design can accurately control the stamping stroke and pressure, ensure the consistency of stamping accuracy and force, thereby ensuring the dimensional accuracy and forming quality of the stamping part, improving production efficiency and product qualification rate, and adapting to the high-quality, mass production requirements of stamping parts in automobile manufacturing.

[0038] Specifically, such as Figure 5 As shown, a collection groove 6 is provided on the rear side of the top of the stamping table 1, and a collection box 7 is provided inside the collection groove 6.

[0039] Specifically, such as Figure 5 As shown, transparent acrylic plates 8 are bolted to both sides of the lifting plate 43, and docking grooves 9 are provided on both sides of the top of the stamping table 1. The docking grooves 9 are located at the bottom of the transparent acrylic plates 8.

[0040] In this embodiment: by setting up a collection trough 6, a collection box 7 and a transparent acrylic plate 8, during the stamping process, the transparent acrylic plate 8 moves with the lifting plate 43 and cooperates with the docking grooves 9 on both sides of the stamping table 1 to further seal the stamping area and reduce the range of splashing impurities and particles during stamping. After the stamping is completed, the particles and impurities that are blown off or fall off will fall into the collection box 7 in the collection trough 6 under the action of gravity, which is convenient for centralized treatment and avoids the accumulation of impurities around the stamping table 1, which will affect the operation of the equipment and the working environment.

[0041] Working Principle: In the manufacturing process of automotive stamping parts, firstly, the hydraulic cylinder 42 fixed at the top of the fixed plate 41 is driven. The telescopic end of the hydraulic cylinder 42 is connected to the lifting plate 43. The lifting plate 43 drives the bottom upper mold 44 to close with the lower mold 2. During operation, the hydraulic cylinder 42 receives power and pushes the lifting plate 43 down along the upright 3, applying precise and sufficient pressure to the automotive stamping part placed in the lower mold 2, causing the stamping part to be plastically deformed to the required shape. Before each stamping, the blower 52 is controlled by the automatic controller 57 to operate, generating gas that is delivered to the multi-hole nozzle 55 through the elastic tube 53. The multi-hole nozzle 55 sprays gas onto the surface of the lower mold 2 to remove residual impurities. When the lifting plate 43 drives the upper mold 44 down, the protective frame 581 moves down accordingly. After its bottom contact rod 583 touches the contact sensor 56, the signal is transmitted to the automatic controller 57, which shuts off the blower 52. At the same time, the lifting plate 43 continues to descend, driving the upper mold 44 to stamp. When the nozzle 55 is compressed, the telescopic spring column 54 retracts and hides inside the cavity 51. The transparent plate 82 inside the protective frame 581 blocks foreign objects from the front and allows operators to observe the stamping area, avoiding interference with operation or misjudgment due to obstructed vision. This ensures that the stamped parts are formed in a clean and safe environment, reducing defective products and improving production quality. After stamping, the lifting plate 43 is brought back by the telescopic end of its hydraulic cylinder 42 to achieve reset. At this time, the touch rod 583 at the bottom of the protective frame 581 disengages from the touch sensor 56, the automatic controller 57 restarts the blower 52, and the telescopic spring column 54 pushes out the multi-hole nozzle 55 to blow away and clean the particles and impurities remaining on the surface of the lower mold 2, ensuring the quality of subsequent stamping. Furthermore, the impurities that are blown off or fall off fall into the collection box 7 in the collection groove 6 behind the stamping table 1 under the action of gravity, which is convenient for centralized treatment, preventing the accumulation of impurities from affecting the operation of the equipment and the working environment, and maintaining the stability and sustainability of production.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
