Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die unloading device. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) in cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the required parts.

[0003] The existing stamping die unloading devices are divided into two types: rigid unloading devices and elastic unloading devices. Currently, most of them use elastic unloading devices. After the stamping process of the stamping die is completed, the product needs to be taken out. Currently, the product is taken out manually and by robots. Manual removal increases the labor intensity, and the structure of robot removal is complex, and the use cost and maintenance cost are high. Therefore, the utility model proposes a stamping die unloading device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a stamping die unloading device, including a workbench 1, a punch 2 and a sliding frame 3. The workbench 1 is provided with a punch 2 on one side, and the workbench 1 is provided with a sliding frame 3 on the top. A slide rail 4 is provided on one side of the workbench 1, and a clamping mechanism is provided on the slide rail 4. A pushing mechanism is provided between the punch 2 and the sliding frame 3. A metal disc is placed in the clamping mechanism, and the clamping mechanism clamps the metal disc. Multiple metal discs are directly stacked and placed on one side of the clamping mechanism. After the punch 2 moves downward, it punches the metal disc, removes the waste at the center of the metal disc to form a complete metal ring piece. When the punch 2 moves upward to reset, the punch 2 drives the lowest end of the stacked metal discs to move toward the clamping mechanism through the pushing mechanism, so as to extrude the metal ring piece out of the internal discharge of the clamping mechanism and feed new metal discs into it.

[0019] A group of fixed feet 11 are symmetrically fixedly connected on both sides of the workbench 1, and the top of the fixed feet 11 is fixedly connected to a limiting rod 10. A plurality of metal discs are arranged inside the limiting rod 10. The plurality of metal discs are stacked on each other and stored on one side of the clamping mechanism through the limiting rod 10.

[0020] The clamping mechanism includes a clamping block 12, a connecting frame 13 and a double-headed cylinder 15. A double-headed cylinder 15 is installed on one side of the bottom of the workbench 1, and both ends of the double-headed cylinder 15 are fixedly connected to the connecting frame 13. The clamping blocks 12 are symmetrically slidably connected to the two sides of the slide rail 4. One side of the workbench 1 is symmetrically provided with a strip groove 14. The top of the connecting frame 13 passes through the interior of the strip groove 14 and is fixedly connected to the bottom of the clamping block 12. The output end of the double-headed cylinder 15 is fixed to the clamping block 12 through the connecting frame 13. The double-headed cylinder 15 can drive the clamping block 12 to slide on the slide rail 4. When the double-headed cylinder 15 drives the two clamping blocks 12 to approach the metal disc at the same time, the two sides of the metal disc can be clamped to fix it under the punch 2. When the output end of the double-headed cylinder 15 drives the clamping block 12 away from the metal disc, the clamping block 12 no longer clamps the metal ring formed by stamping, and it can be pushed out of the clamping mechanism.

[0021] The top height of the slider 5 is equal to the height of the metal disc at the bottom end of the limiting rod 10, and the positions are parallel front and back. The positions of the punch 2 and the slide rail 4 are parallel up and down. The pushing mechanism includes a slider 5, a support rod 6, a rotating rod 7, a connecting rod 8 and a linkage rod 9. The slider 5 is slidably connected inside the sliding frame 3. A support rod 6 is provided on one side of the sliding frame 3. The top of the support rod 6 is hinged with a rotating rod 7. One end of the rotating rod 7 is hinged with a side of the punch 2, and the other end of the rotating rod 7 is hinged with a connecting rod 8. An articulated seat 17 is fixed on the top of the slider 5, and one end of the connecting rod 8 is hinged with one side of the articulated seat 17. The shape of the rotating rod 7 is set to an L-shaped structure. The two ends of the rotating rod 7 are fixedly connected with connecting shafts. The linkage rod 9 and one end of the connecting rod 8 are both provided with When the punch 2 is moved upward, the punch 2 drives the rotating rod 7 to rotate clockwise through the linkage rod 9, and the sliding frame 3 limits the slider 5 to only move in a straight line. The rotating rod 7 pulls the slider 5 toward the clamping mechanism through the connecting rod 8, thereby pushing the metal disc at the bottom end of the limit rod 10 into the clamping mechanism, and the metal disc simultaneously squeezes out the metal ring sheet stamped in the clamping mechanism, thereby driving the metal disc to feed and the metal ring sheet to automatically feed out. When the punch 2 moves downward, the punch 2 drives the rotating rod 7 to rotate counterclockwise through the linkage rod 9, and the rotating rod 7 drives the slider 5 away from the clamping mechanism through the connecting rod 8, and the slider 5 exits the range of the limit rod 10. The metal disc at the bottom of the limit rod 10 automatically falls into the inside of the sliding frame 3 due to gravity, and its position is parallel to the front and back of the slider 5.

[0022] A through groove 16 is provided on one side of the workbench 1, and an arc groove is provided on the inner side of the clamping block 12. The diameter of the through groove 16 is equal to the diameter of the punch 2. The waste formed by the metal disc during the stamping process can fall to the bottom of the workbench 1 through the through groove 16 to avoid it staying on the workbench 1 and affecting the stamping operation.

[0023] When the punch 2 is moved upward by the stamping die unloading device, the punch 2 drives the rotating rod 7 to rotate clockwise through the linkage rod 9, and the sliding frame 3 limits the slider 5 to only linear movement. The rotating rod 7 pulls the slider 5 toward the clamping mechanism through the connecting rod 8, thereby pushing the metal disc at the bottom end of the limit rod 10 into the clamping mechanism, and the metal disc simultaneously squeezes out the stamped metal ring in the clamping mechanism, thereby driving the metal disc to feed and the metal ring to automatically feed out. When the punch 2 moves downward, the punch 2 drives the rotating rod 7 to rotate counterclockwise through the linkage rod 9, and the rotating rod 7 drives the slider 5 away from the clamping mechanism through the connecting rod 8, and the slider 5 exits the range of the limit rod 10. The metal disc at the bottom of the limit rod 10 automatically falls into the inside of the sliding frame 3 due to gravity, and its position is parallel to the front and back of the slider 5.
