[0002] Automobile parts are various components and assemblies that make up an automobile, including engines, transmission systems, chassis, bodies, and interiors, etc., and usually need to be manufactured through precise stamping forming processes. During the stamping forming process, metal sheets are processed by dies through blanking, stretching, bending, etc. to form the required part shapes. In order to ensure the surface quality of the parts, prevent die damage, and improve production efficiency, an anti-chip accumulation structure must be used during stamping. This structure can prevent metal chips and residues from accumulating on the die surface, reduce surface defects and die wear caused by chip accumulation, while reducing the maintenance frequency, extending the die life, improving production stability and overall efficiency. By using the anti-chip accumulation structure, the part quality during the production process and the efficient and stable operation of the production line can be guaranteed.

[0003] In most cases, the existing anti-chip accumulation structures place the metal sheet on the lower template, and adjust the flow rate of the highly volatile stamping oil through a control valve according to production needs, so that the highly volatile stamping oil flows through the pipeline and the outlet at the punching edge, and sprays out from the punching edge of the punch to wash away the possible fine metal chips staying there. However, during use, the chips still fall on the workpiece along with the stamping oil, thus polluting the workpiece. Therefore, an anti-chip accumulation structure for stamping forming of automobile parts is proposed to solve the above problems. Content of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides an anti-chip accumulation structure for stamping forming of automobile parts, aiming to improve the problem that the anti-chip structure adopted in the existing technology is simple in structure and relatively single in function, and cannot meet the use requirements, resulting in chips falling on the workpiece along with the stamping oil and polluting the workpiece.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Refer to Figure 1 、 Figure 2 and Figure 3, An embodiment provided by the present utility model: An anti-chip accumulation structure for stamping forming of automotive parts, including a driving rod 1. A mounting plate 2 is fixedly connected to the lower end of the driving rod 1. A stamping head 3 is fixedly connected to the lower surface of the mounting plate 2. A first connecting rod 4 is slidably connected inside the mounting plate 2. A connecting block 5 is fixedly connected to the upper surface of the first connecting rod 4. A first spring 6 is sleeved on the outer wall of the first connecting rod 4. A first annular block 7 is fixedly connected to the lower surface of the first connecting rod 4. A second annular block 8 is fixedly connected to the lower surface of the first annular block 7. A plurality of collection holes 9 are penetrated and opened inside the second annular block 8. A connecting hose 10 is fixedly connected through one side inside the second annular block 8. One end of the connecting hose 10 is fixedly connected to a fixed box 11. The fixed box 11 is fixedly connected to the upper surface of the mounting plate 2. A collection assembly 12 for collecting debris is installed inside the fixed box 11. A negative pressure box 15 is fixedly connected to the upper surface of the fixed box 11. A third connecting rod 19 is fixedly connected to the upper surface of the connecting block 5. A connecting plate 18 is fixedly connected to the upper surface of the third connecting rod 19. A piston assembly for transmitting gas is installed inside the negative pressure box 15. A connecting pipe 13 is fixedly connected between the fixed box 11 and the negative pressure box 15. A one-way valve 14 is fixedly connected to the outer wall of the connecting pipe 13; The collection assembly 12 includes a collection box 1201. The collection box 1201 is slidably connected inside the fixed box 11. A hollowed-out net 1202 is fixedly connected inside the collection box 1201; The piston assembly includes a second connecting rod 17. The second connecting rod 17 is slidably connected inside the negative pressure box 15. A piston plate 16 is fixedly connected to the lower surface of the negative pressure box 15;

[0023] Specifically, the driving rod 1 drives the movement of the mounting plate 2, thereby driving the stamping head 3 to accurately stamp the workpiece; during this process, some debris will remain on the outer wall of the second annular block 8; when the mounting plate 2 returns to its original position, the reaction force of the first spring 6 drives the third connecting rod 19 on the upper surface of the connecting block 5 to move upward. At this time, the third connecting rod 19 further drives the second connecting rod 17 to move upward; as the second connecting rod 17 moves, the piston plate 16 also moves accordingly, so that the debris is sucked into the inside of the second annular block 8 through the collection holes 9; these debris are then transmitted to the inside of the collection box 1201 through the connecting hose 10 for collection and processing; when it is necessary to clean the debris, just pull the collection box 1201 to conveniently clean and process the debris, thereby ensuring the cleanliness and normal operation of the equipment.

[0024] Refer to Figure 1 、 Figure 2 and Figure 3, on the outer wall of the first annular block 7, a cylindrical block 20 is fixedly connected. There are two cylindrical blocks 20 arranged symmetrically left and right; inside both cylindrical blocks 20, a sliding block 21 is slidably connected. Inside the sliding block 21, a sliding rod 22 is fixedly connected; a second spring 23 is sleeved on the outer wall of the sliding rod 22, and the sliding rod 22 is slidably connected inside the cylindrical block 20; one end of the sliding rod 22 is fixedly connected to an oiling block 24, and the oiling block 24 is slidably connected inside the first annular block 7; one end of the first connecting rod 4 is fixedly connected to the upper surface of the mounting plate 2, and the other end of the first connecting rod 4 is fixedly connected to the lower surface of the connecting block 5;

[0025] Specifically, when the second annular block 8 resets, an appropriate amount of stamping oil is added inside the first annular block 7; when the first annular block 7 passes by the outer wall of the stamping head 3, at this time, through the reaction force of the second spring 23, the sliding block 21 is driven to slide smoothly; during this process, the movement of the oiling block 24 further drives the movement of the sliding rod 22. Through the movement of the sliding rod 22, the oiling block 24 performs a telescopic action; at this time, the stamping oil will be evenly smeared on the outer wall of the stamping head 3 by the oiling block 24, thus achieving the effect of precise adaptive smearing according to different stamping head diameters; through the smearing of the stamping oil, not only can the wear caused by friction during stamping be effectively reduced, but also it can play a role in lubricating and maintaining the stamping head 3, extend the service life of the equipment, and ensure its efficient and stable operation.

[0026] Working principle: During use, the driving rod 1 drives the mounting plate 2 to move, thereby driving the stamping head 3 to stamp the workpiece. At this time, debris will remain on the outer wall of the second annular block 8. When the mounting plate 2 resets, at this time, through the reaction force of the first spring 6, the third connecting rod 19 on the upper surface of the connecting block 5 is driven to move. At this time, the third connecting rod 19 drives the second connecting rod 17 to move upward. At this time, through the movement of the second connecting rod 17, the piston plate 16 is driven to move, and then the debris is sucked into the second annular block 8 through the collection hole 9. At this time, the debris will be transmitted to the inside of the collection box 1201 through the connecting hose 10 for collection and processing. At this time, by pulling the collection box 1201, the effect of cleaning the debris is achieved;

[0027] Secondly, when the second annular block 8 resets, by adding stamping oil inside the first annular block 7, when the first annular block 7 passes by the outer wall of the stamping head 3, at this time, through the reaction force of the second spring 23, the sliding block 21 is driven to slide. At this time, through the movement of the oiling block 24, the sliding rod 22 is further driven to move. Through the movement of the sliding rod 22, the oiling block 24 is driven to expand and contract. At this time, the stamping oil will be smeared on the outer wall of the stamping head 3 by the oiling block 24, thus achieving the effect of adaptive smearing according to different stamping head diameters. By smearing the stamping oil on the outer wall of the stamping head 3, the effect of maintaining the stamping head 3 is further achieved.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
