Description

Technical Field

[0001] This utility model relates to the field of hole-opening device technology, and more specifically, to a hole-opening device for automotive gasket production. Background Technology

[0002] A hole-making device is a mechanical device used to make holes in objects. It is widely used in industries, construction, home decoration and other fields. Its function is to process round, square or other shapes of holes in materials by cutting, punching and other methods to meet the needs of subsequent processing or installation. It is especially widely used in the production of automotive gaskets.

[0003] For example, Chinese Patent Publication No. CN202323612067.4 discloses a hole-opening device for metal gaskets, comprising: a hole-opening machine body; a movable chuck movably mounted on the top of the hole-opening machine body; and an automatic loading and unloading device. By lowering the connecting plate, suction cups contact the metal gaskets on the carrier plate and adsorb them using negative pressure. Another set of suction cups adsorbs the metal gaskets after hole opening. The first electric telescopic rod retracts, causing the connecting plate to rise. When the motor starts, the threaded rod rotates, and the movable block moves to one side. When the suction cup with the unopened gasket moves above the movable chuck, it stops moving. The connecting plate lowers, and after the metal gasket contacts the movable chuck, the suction cup releases its adsorption, allowing the movable chuck to clamp the metal gasket. At this point, the metal gasket with the hole open falls onto the inclined plate. Subsequently, the second electric telescopic rod pushes the movable chuck below the drilling needle to open the hole. Using this structure, the loading and unloading of metal gaskets can be performed simultaneously, achieving the effect of improving work efficiency.

[0004] However, in the aforementioned technical solutions, gaskets, as crucial sealing and cushioning components in the automotive parts manufacturing process, directly impact the overall performance of the production line through their drilling accuracy and efficiency. Traditional gasket drilling methods typically employ a single mold for batch processing. This approach offers certain efficiency advantages when dealing with large-volume production tasks of a single specification. However, with the increasing demand for personalization and diversification in the automotive industry, small-batch, multi-variety production models are gradually becoming mainstream. In this context, the traditional single-mold drilling method reveals significant limitations: long mold changeover times and high costs, difficulty in quickly responding to diverse order requirements for gasket shape, size, and specifications, resulting in low production efficiency and an inability to meet the market's stringent requirements for product diversity and delivery time. Utility Model Content

[0005] The main objective of this invention is to provide a hole-opening device for automotive gasket production. This device effectively addresses the issue that in the production of automotive parts, gaskets, as crucial sealing and buffering elements, directly impact the overall performance of the production line due to their hole-opening accuracy and efficiency. Traditional gasket hole-opening methods typically employ a single mold for batch processing. While this approach offers efficiency advantages for large-volume production tasks of single specifications, the increasing demand for personalization and diversification in the automotive industry has led to the rise of small-batch, multi-variety production models. In this context, the traditional single-mold hole-opening method reveals significant limitations: long mold changeover times and high costs, difficulty in quickly responding to diverse order requirements for gasket shape, size, and specifications, resulting in low production efficiency and an inability to meet the market's stringent requirements for product diversity and delivery time.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a hole-opening device for automotive gasket production, comprising a base, a first groove provided on the base, an electric push rod and a moving component provided in the first groove, a plurality of through slots and a plurality of lower molds provided on the moving component, a sliding column slidably provided in the through slots, a spring and a hole-opening cutter fixedly provided on one side of the sliding column, a second groove provided between the lower mold and the through slot, and a plurality of directional markers provided on the outer wall surface of one side of the moving component.

[0007] Preferably, the electric push rod is fixedly installed in the first groove, and the spring is fixedly installed in the through groove.

[0009] Preferably, the movable component includes a component base, on which a threaded post is threadedly disposed, the threaded post being rotatably connected to the base, and a motor being disposed on one side of the threaded post.

[0010] Preferably, the movable component has a cleaning ring fixedly disposed on the inner wall surface of the channel, and a guide slider is slidably disposed on one side of the component base.

[0011] Preferably, the component base slides in the first groove, the motor is fixedly mounted on the base, and the guide slider is fixedly mounted in the first groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) This utility model first installs different hole-opening tools and lower molds onto the moving component. Then, the motor drives the threaded column to rotate, and the threaded column moves the component base to one side. The hole-opening tool moves with the component base, and the required hole-opening tool and lower mold are moved to the position directly below the electric push rod. Then, the raw material is placed in the second groove. The electric push rod is used to press the sliding column located directly below the electric push rod. The spring deforms, and the sliding column drives the hole-opening tool to move towards the raw material to open the hole. When it is necessary to switch the hole-opening tool and lower mold as needed, the above steps can be repeated to quickly complete the switching of the hole-opening tool and lower mold, which improves flexibility and versatility. It can adapt to the hole-opening requirements of gaskets of different shapes, sizes and specifications. It is especially suitable for small-batch, multi-variety production mode, so that the production line can quickly respond to different order requirements. Attached Figure Description

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 and Figure 2As shown, an opening device for producing automotive gaskets includes a base 1. A first groove 2 is provided on the base 1. An electric push rod 3 and a moving component 4 are provided in the first groove 2. A plurality of through slots 5 and a plurality of lower molds 9 are provided on the moving component 4. A sliding column 7 is slidably provided in the through slot 5. A spring 6 and an opening cutter 8 are fixedly provided on one side of the sliding column 7. A second groove 10 is provided between the lower molds 9 and the through slots 5. A plurality of pointers 11 are provided on the outer wall surface of one side of the moving component 4.

[0020] like Figure 3 As shown, in another embodiment of the present invention, the movable component 4 includes a component base 401, a threaded post 402 is threaded on the component base 401, the threaded post 402 is rotatably connected to the base 1, and a motor 403 is provided on one side of the threaded post 402.

[0021] The movable component 4 has a cleaning ring 404 fixedly installed on the inner wall surface of the through groove 5, and a guide slider 405 is slidably installed on one side of the component base 401.

[0022] When the component base 401 needs to be moved, the motor 403 first drives the threaded column 402 to rotate, and then the threaded column 402 moves the component base 401 to one side. The cleaning ring 404 is responsible for cleaning the surface of the cutting part of the hole-opening tool 8 when the hole-opening tool 8 retracts into the through groove 5, so as to prevent impurities from adhering to the surface of the cutting part of the hole-opening tool 8.

[0023] The working principle of an opening device for automotive gasket production:

[0024] In use, firstly, different punching tools 8 and lower molds 9 are installed on the moving assembly 4. Then, the motor 403 drives the threaded column 402 to rotate, and the threaded column 402 moves the assembly base 401 to one side. The punching tool 8 moves with the assembly base 401, moving the required punching tool 8 and lower mold 9 directly below the electric push rod 3. Then, the raw material is placed in the second groove 10, positioned directly below the electric push rod 3. The electric push rod 3 is then moved towards the moving assembly 4, pressing the sliding column 7 located directly below it, causing the sliding column 7 to move towards the second groove 10. The spring 6 deforms, and the sliding column 7 moves the punching tool 8. The punching tool 8 is moved towards the raw material to punch a hole. After punching, the electric push rod 3 returns to its original position, and the spring 6 rebounds, causing the punching tool 8 to retract into the through groove 5. At this time, the cleaning ring 404 is used to clean the surface of the cutting part of the punching tool 8 to prevent impurities from adhering to the surface of the cutting part of the punching tool 8. When it is necessary to switch between the punching tool 8 and the lower mold 9 as needed, the above steps can be repeated to quickly complete the switching between the punching tool 8 and the lower mold 9, which improves flexibility and versatility and can adapt to the punching requirements of gaskets of different shapes, sizes and specifications. It is especially suitable for small-batch, multi-variety production mode, enabling the production line to quickly respond to different order requirements.

[0025] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
