Description

Technical Field

[0001] The utility model relates to the field of automobile parts processing equipment, in particular to a punching mechanism for automobile interior parts. Background Art

[0002] In the automobile manufacturing industry, during the production process of interior parts such as seat cushions and leather, precise punching operations are often required for subsequent assembly and function realization. Currently, in order to enhance the high-class sense of the interior of the vehicle, the leather used for automobile seat cushions is punched and patterned to improve the breathability of the leather while enhancing the aesthetics of the interior. However, the existing automobile interior punching equipment cannot firmly fix the interior parts, resulting in large errors during the punching operation. During punching, leather waste will accumulate on the working table of the punching machine, reducing the punching effect and affecting work efficiency. Summary of the Utility Model

[0003] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a punching mechanism for automobile interior parts, which is used to solve the problems of large punching errors and lack of waste treatment devices in the prior art.

[0004] To achieve the above purpose and other related purposes, the present utility model provides the following technical solutions:

[0005] A punching mechanism for automobile interior parts includes a working table, a punching device arranged at the upper end of the working table, and a material receiving device arranged at the lower end of the working table. The punching device includes a bottom plate, a vertical plate fixed to the bottom plate, and a top plate fixed to the top end of the vertical plate. A punching driving unit is arranged on the top plate. A punch is arranged on the output shaft of the punching driving unit. Mounting plates are symmetrically arranged at the left and right ends of the punch. A guiding device is arranged between the mounting plates and the top plate. A material pressing device is arranged at the lower end of the mounting plate.

[0006] Implementing the above technical solution, the punching driving unit is installed on the top plate. The punching driving unit generates driving force through a motor or a hydraulic power source and transmits it to the punch via the output shaft, enabling the punch to perform rapid reciprocating motion in the vertical direction to complete the punching action. The mounting plates symmetrically arranged at the left and right ends of the punch, and the guiding device ensures the linearity and stability of the punch during the up and down movement, preventing processing errors caused by deflection. The function of the material pressing device is to press the interior part to be processed tightly on the working table before punching, avoiding workpiece displacement caused by vibration or external force during the punching process, thereby affecting the punching accuracy and quality. The present application effectively reduces the rejection rate caused by processing errors and improves the punching quality through precise punching and stable workpiece fixation.

[0007] In an embodiment of the present utility model, a cushion plate is provided on the bottom plate, an adsorption device is provided on the cushion plate, a through blanking hole is formed in the middle of the adsorption device, the cushion plate and the bottom plate, a collecting hopper is provided at the lower end of the blanking hole, and the material receiving device is provided at the lower end of the collecting hopper.

[0008] To achieve the above technical solution, the cushion plate is placed on the bottom plate, and an adsorption device is configured on the cushion plate. This device can generate sufficient adsorption force to stably adsorb the workpiece placed on it, ensuring that the workpiece will not displace during the punching process and maintaining the accuracy of the punching position. After punching is completed, the punched waste will fall through the through blanking hole in the middle of the cushion plate, the adsorption device and the bottom plate, and fall into the material receiving device through the collecting hopper. The design of the collecting hopper and the material receiving device realizes the automatic collection of punching waste, eliminating the need for frequent manual cleaning, improving production efficiency, and reducing the labor intensity of operators. The waste is effectively collected and managed, avoiding the mess at the production site and reducing environmental pollution.

[0009] In an embodiment of the present utility model, the guiding device includes a guide sleeve provided on the top plate, a guide post passing through the guide sleeve, the lower end of the guide post is fixed on the mounting plate, and a buffer spring is sleeved on the guide post between the mounting plate and the top plate.

[0010] To achieve the above technical solution, the guide sleeve is fixed on the top plate, and the guide post passes through the guide sleeve, with its lower end connected to the mounting plate, forming a linear guiding structure. The buffer spring is sleeved on the guide post between the mounting plate and the top plate. When the punch moves downward for punching operation, the buffer spring can absorb the impact force generated at the moment of contact between the punch and the workpiece, reducing the vibration impact on the punch and the entire punching device. At the same time, it also helps the punch to smoothly return to the initial position after punching, avoiding hard collision and extending the service life.

[0011] In an embodiment of the present utility model, the blanking device includes a blanking spring located at the lower end of the mounting plate, a blanking plate located at the lower end of the blanking spring, and a blanking protrusion located at the lower end of the blanking plate.

[0012] To achieve the above technical solution, the blanking device is arranged at the lower end of the mounting plate. Its function is to preload pressure before punching. When the punching driving unit drives the punch to descend, the blanking spring is compressed, generating sufficient pressure to tightly press the blanking plate and the blanking protrusion against the workpiece, preventing the workpiece from displacing due to vibration during punching. The blanking protrusion can be designed according to the specific shape of the workpiece to directly contact and apply force to a specific part of the workpiece, ensuring the stability of the workpiece during punching.

[0013] In an embodiment of the present utility model, the adsorption device includes an adsorption plate, an adsorption cavity located at the lower end of the adsorption plate, and a plurality of adsorption holes formed in the adsorption plate and communicating with the adsorption cavity.

[0014] To implement the above technical solution, the adsorption plate is located above the backing plate and is in direct contact with the workpiece. It is usually made of non-magnetic material to avoid unnecessary magnetic interference with metal workpieces. The adsorption cavity is arranged below the adsorption plate and is connected to an external vacuum pump or negative pressure source through a pipeline or channel. When the vacuum pump or negative pressure source is turned on, a negative pressure is generated in the adsorption cavity. The adsorption holes are opened on the adsorption plate and communicate with the adsorption cavity. The number and distribution depend on the size and shape of the workpiece. When a negative pressure is formed in the adsorption cavity, the air between the workpiece surface and the adsorption plate is pumped out through the adsorption holes to form an adsorption force, thereby firmly fixing the workpiece on the adsorption plate.

[0015] In an embodiment of the present invention, the material receiving device includes a material receiving box, universal wheels located at the lower end of the material receiving box, and a handle provided on the material receiving box.

[0016] To implement the above technical solution, the design purpose of the material receiving device is to facilitate the collection and treatment of waste generated during the punching process. The universal wheels are installed at the lower end of the material receiving box, enabling the material receiving box to move easily. The handle is provided on the material receiving box, usually on the side, for easy pushing and pulling of the material receiving box by the operator.

[0017] As described above, a punching mechanism for automotive interior parts of the present invention has the following beneficial effects: The punching drive unit is installed on the top plate. The punching drive unit generates a driving force through a motor or a hydraulic power source and transmits it to the punch via the output shaft, enabling the punch to perform rapid reciprocating motion in the vertical direction to complete the punching action. The mounting plates symmetrically arranged at the left and right ends of the punch, and the guiding device ensures the linearity and stability of the punch during the up and down movement, preventing processing errors caused by deflection. The function of the blank holding device is to press the interior part to be processed tightly on the workbench before punching, avoiding workpiece displacement caused by vibration or external force during the punching process, thereby affecting the accuracy and quality of punching. Through precise punching and stable workpiece fixation in this application, the rejection rate caused by processing errors is effectively reduced, and the punching quality is improved.

[0024] The punching drive unit 5 is installed on the top plate 4. The punching drive unit 5 generates a driving force through a motor or a hydraulic power source and transmits it to the punch 6 via the output shaft, enabling the punch 6 to perform rapid reciprocating motion in the vertical direction to complete the punching operation. The mounting plates 7 symmetrically arranged at the left and right ends of the punch 6, and the guiding device ensures the linearity and stability of the punch 6 during the up and down movement, preventing processing errors caused by deflection. The function of the blank holding device is to press the interior part to be processed against the workbench 1 before punching, avoiding workpiece displacement caused by vibration or external force during the punching process, thereby affecting the punching accuracy and quality. In this application, through precise punching and stable workpiece fixation, the reject rate caused by processing errors is effectively reduced, and the punching quality is improved.

[0025] A backing plate 2 is provided with a cushion plate 8, and an adsorption device is provided on the cushion plate 8. A through blanking hole 9 is formed in the middle of the adsorption device, the cushion plate 8, and the backing plate 2. A collecting hopper 10 is provided at the lower end of the blanking hole 9, and the receiving device is provided at the lower end of the collecting hopper 10. The above technical solution mainly relates to the process of waste material treatment after punching. Specifically, the cushion plate 8 is placed on the backing plate 2, and an adsorption device is configured on the cushion plate 8. This device can generate sufficient adsorption force to stably adsorb the workpiece placed on it, ensuring that the workpiece will not be displaced during the punching process and maintaining the accuracy of the punching position. After punching, the punched waste materials (such as metal chips, plastic sheets, etc.) will fall through the through blanking hole 9 in the center of the cushion plate 8, the adsorption device, and the backing plate 2, and fall into the receiving device through the collecting hopper 10. The design of the collecting hopper 10 and the receiving device realizes the automatic collection of punching waste materials, eliminating the need for frequent manual cleaning, improving production efficiency, and reducing the labor intensity of operators. The waste materials are effectively collected and managed, avoiding the mess at the production site and reducing environmental pollution.

The lower end of the guide post 12 is fixed on the mounting plate 7, and a buffer spring 13 is sleeved on the guide post 12 between the mounting plate 7 and the top plate 4. The guide sleeve 11 is fixed on the top plate 4, and the guide post 12 passes through the guide sleeve 11 and is connected to the mounting plate 7 at its lower end, forming a linear guiding structure. The buffer spring 13 is sleeved on the guide post 12 between the mounting plate 7 and the top plate 4. When the punch 6 moves downward for punching operation, the buffer spring 13 can absorb the impact force generated at the moment when the punch 6 contacts the workpiece, reducing the vibration impact on the punch 6 and the entire punching device. At the same time, it also helps the punch 6 to smoothly return to the initial position after punching, avoiding hard collision and extending the service life.

[0027] The blanking pressure device includes a blanking pressure spring 14 at the lower end of the mounting plate 7, a blanking pressure plate 15 at the lower end of the blanking pressure spring 14, and a blanking pressure protrusion 16 at the lower end of the blanking pressure plate 15. The blanking pressure device is arranged at the lower end of the mounting plate 7, and its function is to preload pressure before punching. When the punching driving unit 5 drives the punch 6 to descend, the blanking pressure spring 14 is compressed, generating sufficient pressure to tightly press the blanking pressure plate 15 and the blanking pressure protrusion 16 against the workpiece, preventing the workpiece from being displaced due to vibration during punching. The blanking pressure protrusion 16 can be designed according to the specific shape of the workpiece and is used to directly contact and apply force to a specific part of the workpiece to ensure the stability of the workpiece during punching.

[0028] The adsorption device includes an adsorption plate 17, an adsorption cavity 18 located at the lower end of the adsorption plate 17, and a plurality of adsorption holes 19 formed in the adsorption plate 17 and communicating with the adsorption cavity 18. The adsorption plate 17 is located above the backing plate 8 and is in direct contact with the workpiece. It is usually made of non-magnetic material to avoid unnecessary magnetic interference with the metal workpiece. The adsorption cavity 18 is arranged below the adsorption plate 17 and is connected to an external vacuum pump or negative pressure source through a pipeline or a channel. When the vacuum pump or negative pressure source is turned on, negative pressure is generated in the adsorption cavity 18. The adsorption holes 19 are formed in the adsorption plate 17 and communicate with the adsorption cavity 18. The number and distribution thereof are determined according to the size and shape of the workpiece. When negative pressure is formed in the adsorption cavity 18, the air between the workpiece surface and the adsorption plate 17 is pumped out through the adsorption holes 19 to form an adsorption force, thereby firmly fixing the workpiece on the adsorption plate 17.

[0029] The material receiving device includes a material receiving box 20, universal wheels 21 located at the lower end of the material receiving box 20, and a handle 22 arranged on the material receiving box 20.
