Description

Technical Field

[0001] This utility model relates to the field of mold technology for manufacturing medium-flat pressing rings, specifically a stamping mold based on the manufacturing of medium-flat pressing rings. Background Technology

[0002] Existing die-casting for medium-flat blank holders typically involves cutting, pressing, shaping, welding, and grinding the weld joints. This process is complex, labor-intensive, and inefficient due to the low production efficiency of manual welding and grinding.

Therefore, a new stamping die for medium-flat blank holders was designed, reducing the original five-step process to three steps and replacing the welding and grinding processes. All steps are now mechanically executed, eliminating welding and grinding, resulting in more regular and flat blank holders. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figure 1-5A stamping die based on a flat blanking ring includes a blanking die A, a stretching die B, and a breaking die C. Each of the blanking die A, stretching die B, and breaking die C includes a lower die 1 and an upper die 2. The die also includes a frame for facilitating the opening and closing of the lower die 1 and the upper die 2. The frame includes a loading station, an opening / closing station, and an unloading station arranged in parallel. The frame also includes a lower slide rail 5 that runs horizontally through the loading station, the opening / closing station, and the unloading station, and an upper slide rail 6 located at the opening / closing station. The lower slide rail 5 and the upper slide rail 6 are supported by multiple support columns. The fixed connection also includes a lower sliding frame 3 and an upper sliding frame 4 arranged in a group. The lower mold 1 can be vertically locked inside the lower sliding frame 3, and the upper mold 2 is set at the bottom of the upper sliding frame 4 through an elastic tensioning mechanism. The lower sliding frame 3 and the upper sliding frame 4 can be guided and slidably engaged with the lower sliding rail 5 and the upper sliding rail 6, respectively. The upper sliding rail 6 is equipped with a laterally movable pressing mechanism. By changing the original five processes of cutting, pressing, shaping, welding, and grinding the weld joint in the production of the middle flat pressing ring to three processes of blanking, stretching and forming, and breaking the top, the manufacturing process is reduced and the production efficiency is improved.

[0023] Specifically, each of the four corners of the sliding frame 3 is fixedly equipped with a limiting strip 13 that slides vertically with the upper mold 2. The four limiting strips 13 facilitate vertical guidance of the upper mold 2 and the upper sliding frame 4 as a whole, and facilitate horizontal movement of the whole.

[0024] Specifically, the elastic stretching mechanism includes a tension spring 12. The upper mold 2 has a lifting and limiting slide groove on its side. A vertical slide rod 10 is fixedly installed on the upper slide frame 4, which slides with the upper mold 2 and extends into the lifting and limiting slide groove and is fixedly connected to the limiting block 11. The tension spring 12 is sleeved on the vertical slide rod 10, and the two sides of the tension spring 12 are fixedly connected to the upper slide frame 4 and the upper mold 2 respectively. Through the cooperation of the lifting and limiting slide groove, the tension spring 12, the vertical slide rod 10 and the limiting block 11, the upper mold 2 is automatically stretched up after being pressed down by the pressing mechanism. At the same time, through the cooperation of the limiting block 11 and the lifting and limiting slide groove, the descent height of the upper mold 2 is limited to prevent the upper mold 2 from separating from the upper slide frame 4.

[0025] Specifically, the pressing mechanism includes a movable slide 7 that can slide laterally on the upper slide rail 6. A downward-facing pressing block 8 is installed on the movable slide 7 via a lifting drive cylinder 9. A through groove is provided on the upper slide frame 4 for the pressing block 8 to pass through. By moving the movable slide 7 directly above the upper mold 2 to be pressed, the lifting drive cylinder 9 is activated to drive the pressing block 8 to press down and pass through the through groove to press the upper mold 2 down. Then, the pressing block 8 is reset upward by the lifting drive cylinder 9.

[0026] Specifically, it also includes a lateral movement assembly for driving the movable slide 7 to move laterally. The lateral movement assembly includes a screw 14 rotatably connected to the top of the upper slide rail 6 and a guide slide rod 15 arranged parallel to the screw 14 and fixedly connected to the lower mold 1. The movable slide 7 is threadedly connected to the pressure block 8 and the movable slide 7 is guided and slidably engaged with the guide slide rod 15. It also includes a drive motor 16 for driving the screw 14 to rotate. The drive motor 16 is fixedly installed on the top of the upper slide rail 6. The lateral movement assembly facilitates the lateral movement of the movable slide 7. When the drive motor 16 is started, the output shaft of the drive motor 16 rotates clockwise or counterclockwise, thereby driving the screw 14 to rotate clockwise or counterclockwise, thereby driving the movable slide 7 to move to the left or right, thus facilitating the adjustment of the lateral position.

[0027] In use, first place the lower sliding frame 3 with the lower mold 1 on it at the loading station, then place the upper sliding frame 4 with the upper mold 2 on its bottom above the lower mold 1, and then align the upper sliding frame 4 with the upper slide rail 6. Then push the lower sliding frame 3 and the upper sliding frame 4 together from the loading station into the opening and closing station. Then place the workpiece above the lower mold 1, and then the upper mold 2 can be moved down by the horizontally movable pressing mechanism. The upper mold 2 presses down and cooperates with the lower mold 1 to form a stamping process. After the stamping is completed, the upper mold 2 rises and resets under the action of the elastic tensioning mechanism, and then continues to push the whole thing to the unloading station. Finally, the lower mold 1 and the upper mold 2 can be unloaded together through the unloading station. Then the loading, stamping opening and closing and unloading operations can be performed at the same time.
