Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal parts, and specifically relates to a continuous stamping die for sheet metal parts. Background Technique

[0002] Sheet metal is a comprehensive cold working process for metal sheets, including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as automobile body), etc. Its remarkable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts. Sheet metal parts referred to in different industries are generally different and are mostly used for calling during assembly.

[0003] After retrieval, the existing patent (publication number: CN218079959U) discloses a stamping die, which includes an upper die base and a lower die base. The upper die base is provided with a lower pressing surface and a pressing head, the lower die base is provided with a receiving surface, a pressing groove is recessed in the receiving surface, and the receiving surface is also provided with a groove. The stamping die further includes a blanking device, and the blanking device includes a blanking block slidably connected to the upper die base. The blanking block protrudes downward from the lower pressing surface, and the blanking block is always subjected to an elastic force that approaches or moves away from the pressing head in the horizontal direction; after the upper die base presses down, the blanking block can be pressed by the lower die, so that the blanking block overcomes the gradually increasing elastic force and slides in the direction away from the pressing head to be received in the groove. Beneficial effects: After stamping is completed, the upper die base rises. At this time, the blanking block will be gradually reset under the action of the elastic force. When reset to the initial position, because it is close to the edge of the pressing head, the pressing head and the metal part are separated, avoiding strip material, and there is no need for manual strip material separation.

[0004] However, in the working process of stamping sheet metal parts with the existing continuous stamping die for sheet metal parts, the raw material of the sheet metal part is easy to overflow inside the injection mold during stamping. After stamping is completed, the sheet metal part needs to be demolded, and during demolding, the sheet metal part is easy to adhere to the inner wall of the stamping die, resulting in difficult demolding and other phenomena, thereby greatly reducing the practicability of the stamping die.

[0005] Therefore, a continuous stamping die for sheet metal parts is proposed for the above problems. Content of the Utility Model

[0027] Among them: during the working process of the continuous stamping die for sheet metal parts when stamping the sheet metal parts, by setting the demolding mechanism 3, it can be avoided that during the working process of stamping the sheet metal parts, the raw material of the sheet metal parts is likely to overflow inside the injection mold during stamping. After stamping is completed, the sheet metal parts need to be demolded, and when demolding, the sheet metal parts are easily adhered to the inner wall of the stamping die, resulting in difficult demolding and other phenomena, thereby greatly reducing the practicality of the stamping die.

[0028] Please refer to Figure 2 , a continuous stamping die for sheet metal parts, the demolding mechanism 3 includes a chute a301, the chute a301 is opened on the surface of the lower die 2, a slider a302 is arranged inside the chute a301, a rack 303 is arranged on the surface of the slider a302, a gear 304 is meshed and connected on one side of the rack 303, a rotating shaft 305 is sleeved inside the gear 304, a handle 306 is arranged on one side of the rotating shaft 305, a connecting block 307 is arranged above the rack 303, a hinge a3071 is arranged on one side of the connecting block 307, a support block 3072 is arranged above the hinge a3071, a hinge b3073 is arranged on one side of the support block 3072, a telescopic rod 3074 is arranged on one side of the hinge b3073, a chute b3075 is opened on the surface of the telescopic rod 3074, a slider b3076 is arranged inside the chute b3075, a telescopic sleeve 3077 is arranged on the surface of the slider b3076, and a blade 3078 is arranged on one side of the telescopic sleeve 3077.

[0029] Among them: During the working process of the continuous stamping die for sheet metal parts to stamp the sheet metal parts, the handle 306 can be rotated first. Under the action of the handle 306, the handle 306 drives the rotating shaft 305 to rotate, the rotating shaft 305 drives the gear 304 to rotate, the gear 304 drives the rack 303 to move, the rack 303 drives the connecting block 307 to move, and the connecting block 307 drives the blade 3078 to move. Thus, the surface of the sheet metal part can be easily scraped by the blade 3078, and then the sheet metal part can be demolded, avoiding the raw material of the sheet metal part from easily overflowing inside the injection mold during stamping. After stamping is completed, the sheet metal part needs to be demolded. And during demolding, the sheet metal part is easily adhered to the inner wall of the stamping die, resulting in difficult demolding and other phenomena. At the same time, under the action of the chute a301 and the slider a302, the moving position of the rack 303 can be limited.

After stamping is completed, the sheet metal part needs to be demolded. And during demolding, the sheet metal part is likely to adhere to the inner wall of the stamping die, resulting in difficult demolding and other phenomena. At the same time, under the action of the chute a 301 and the slider a 302, the moving position of the rack 303 can be limited.

Thus, the angle of the blade 3078 can be adjusted. At the same time, under the action of the chute b 3075 and the slider b 3076, the telescopic sleeve 3077 can be driven to extend, and then the telescopic sleeve 3077 drives the blade 3078 to extend. Secondly, by providing a damping mechanism 4, the spring 404 can be welded below the lower die 2 first. Under the telescopic and resetting action of the spring 404, the lower die 2 can be damped. And under the action of the slide rail 402 and the pulley 403, the spring 404 can be prevented from shaking.
