These parts or components are usually used in the manufacture of various products such as automobiles, electronic devices, household appliances, building structures, etc. In the process of sheet metal part processing, in order to ensure that the processed sheet metal parts have high repeatability and consistency in size and shape, stamping dies need to be used.

[0003] In the prior art, there are the following defects: during the stamping process of existing sheet metal parts, since small waste chips may fall off during the stamping process of sheet metal parts, if the waste chips are not cleaned up, it is easy to affect the precision of subsequent sheet metal part stamping. Common stamping machines require manual cleaning, and the cleaning process may cause wear of the die. Secondly, most dies are installed by bolts, and in actual operation, additional tools are needed to twist the bolts multiple times for disassembly and assembly, which is rather cumbersome in actual operation and cannot further improve the disassembly and assembly efficiency. Therefore, a stamping die for sheet metal part processing is proposed to solve the above problems. Content of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a stamping die for sheet metal part processing, aiming to improve the problem that manual cleaning in the prior art may cause wear of the die by waste chips.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figures 1 - 3, an embodiment provided by the present utility model: a stamping die for sheet metal part processing, including a processing table 1. A hydraulic rod is arranged at the upper end of the processing table 1, and the movable end of the hydraulic rod is connected to the upper die through a mounting seat 7. The upper die and the lower die 8 cooperate to complete the entire stamping process. This is prior art and will not be elaborated here. The disassembly and assembly methods of the upper die and the lower die 8 are the same. A rotating shaft 2 is penetrated and rotatably connected to the inner wall of the processing table 1. The rotating shaft 2 is the rotation point of the connecting plate 6 and can drive the connecting plate 6 to flip through the rotating shaft 2. A limiting mechanism is arranged on the inner wall of the rotating shaft 2. The left end of the rotating shaft 2 is fixedly connected to a connecting plate 6. The connecting plate 6 mainly serves to connect and support the mounting seat 7. The top end of the connecting plate 6 is fixedly connected to a mounting seat 7. The inner wall of the mounting seat 7 is inserted with a lower die 8. The lower die 8 is prior art and different models of the lower die 8 can be used according to different processing techniques. This will not be elaborated here. A collection box 9 is inserted into the inner wall of the processing table 1. The collection box 9 can collect the waste chips generated by sheet metal stamping, facilitating subsequent centralized cleaning. A blower gun 10 is arranged on the left side wall of the processing table 1. The blower gun 10 is prior art and is connected to an existing air duct, enabling the blower gun 10 to generate sufficient wind force to blow off the waste chips on the surface of the lower die 8.

[0032] Referring to Figures 2 - 5 , a limiting block 12 is elastically connected to the right inner wall of the mounting seat 7 through a positioning spring 11. The upper end of the limiting block 12 is beveled. When the bevel surface is squeezed, the limiting block 12 will move horizontally along the inner wall of the mounting seat 7. The right end of the limiting block 12 is fixedly connected to a U-shaped frame 13. The U-shaped frame 13 mainly serves to connect the limiting block 12, and the limiting block 12 can be driven to move through the U-shaped frame 13. A fixing plate 14 is fixedly connected to the inner wall of the lower die 8. The fixing plate 14 is located at the insertion position of the limiting block 12 and the lower die 8. The right inner wall of the mounting seat 7 is fixedly connected to one end of the positioning spring 11. When the limiting block 12 moves to the right, it will compress the positioning spring 11. When resetting, the elastic force of the positioning spring 11 is used to drive the limiting block 12 to reset. The other end of the positioning spring 11 is fixedly connected to the right end of the limiting block 12. The limiting block 12 is slidably connected to the inner wall of the mounting seat 7. The limiting block 12 is inserted into the side wall of the lower die 8. A notch corresponding to the limiting block 12 is opened on the side wall of the lower die 8, enabling the limiting block 12 to be inserted into its notch to limit the entire lower die 8. The limiting block 12 is inserted into the outer wall of the fixing plate 14. An opening corresponding to the fixing plate 14 is opened at the lower end of the limiting block 12, enabling the opening to coincide with the fixing plate 14, increasing the stability of the entire lower die 8 after connection.

[0033] Referring to Figures 1 - 3, the connecting plate 6 is rotatably connected to the inner wall of the processing table 1. There is a certain gap at the turning point of the connecting plate 6 on the processing table 1, which can meet the normal turning of the connecting plate 6 without causing movement interference. The limiting mechanism includes a pull plate 4. The outer wall of the pull plate 4 has a convex part, which can make the convex part of the pull plate 4 slide on the inner wall of the rotating shaft 2, or make the convex part of the pull plate 4 drive the rotating shaft 2 to rotate. The pull plate 4 is slidably connected to the inner wall of the rotating shaft 2. A plug 5 is fixedly connected to the inner side wall of the pull plate 4. The left end of the pull plate 4 is elastically connected to the rotating shaft 2 through a return spring 3. The left end of the pull plate 4 is fixedly connected to one end of the return spring 3. When the pull plate 4 moves to the right, it will stretch the return spring 3. When resetting, the return spring 3 is used to drive the pull plate 4 to reset. The other end of the return spring 3 is fixedly connected to the left end inner wall of the rotating shaft 2. The plug 5 is inserted into the right end side wall of the processing table 1. As Figure 1 shown, symmetrically arranged notch openings are provided on the processing table 1, which can allow the plug 5 to be inserted into the notch openings to limit the position of the entire rotating shaft 2.

[0034] Working principle: First, when it is necessary to clean the waste chips on the surface of the lower mold 8, only need to pull the pull plate 4 to drive the plug 5 to move to the right and stretch the return spring 3, so that the plug 5 is separated from the notch opening on the right end side wall of the processing table 1. Then rotate the pull plate 4 to drive the rotating shaft 2, the connecting plate 6, the mounting seat 7 and the lower mold 8 to turn 180 degrees, so that the lower mold 8 enters the inside of the processing table 1 and faces downward. Then release the pull plate 4 and use the reverse elastic force of the return spring 3 to drive the pull plate 4 and the plug 5 to reset to the right, so that the plug 5 is inserted into the notch opening on the right end side wall of the processing table 1. At this time, start the air gun 10 to make the wind generated by the air gun 10 blow off the waste chips attached to the surface of the lower mold 8. After the cleaning is completed, turn off the air gun 10 so that the waste chips fall into the collection box 9 for collection due to their own gravity. When using the lower mold 8, according to the above operation steps, first release the limit on the rotating shaft 2 and the connecting plate 6, turn 180 degrees to make the lower mold 8 face upward for use, and finally insert the plug 5 into the notch opening on the right end side wall of the processing table 1 for limiting.

[0035] When the lower mold 8 is worn or replaced, only need to move the U-shaped frame 13 to drive the limit block 12 to move to the right and compress the positioning spring 11, so that the limit block 12 is separated from the side wall notch opening of the lower mold 8 and the fixed plate 14. Then take out the lower mold 8 from the inner wall of the mounting seat 7. Then release the U-shaped frame 13 and use the reverse elastic force of the positioning spring 11 to drive the limit block 12 to reset. When installing different models of the lower mold 8, only need to insert the lower mold 8 into the inner wall of the mounting seat 7, so that the bottom end of the mounting seat 7 presses the inclined surface of the limit block 12, so that the limit block 12 drives the U-shaped frame 13 to move to the right and compress the positioning spring 11. When the side wall notch opening of the lower mold 8 coincides with the limit block 12, use the reverse elastic force of the positioning spring 11 to drive the limit block 12 and the U-shaped frame 13 to reset, so that the limit block 12 is respectively inserted into the side wall notch opening of the lower mold 8 and the fixed plate 14. The installation is simple and convenient and the connection is stable.

[0036] 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 for 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.
