Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of stamping dies, and in particular to a feeding mechanism for stamping dies. Background Technology
[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). At room temperature, pressure is applied to the material using dies mounted on a press, causing it to separate or plastically deform, thereby achieving the desired shape. They are a common type of industrial production mold.
[0003] Currently, in the process of stamping sheet metal, automatic feeding is generally accomplished by automated equipment. For example, patent CN219402038U discloses a stamping die feeding mechanism. When using this device, the sheet metal to be processed can be placed in the feeding tray 13. Then, the motor 402 is started in the forward direction. The motor 402 drives the first rotating shaft 403 and the rotating rod 404 to rotate synchronously, so that the fixed column 406 can move from the lower right side to the lower left side of the limiting groove 8. The fixed column 406 can drive the moving rod 407 and the moving plate 408 to move synchronously. Then, the sheet metal to be processed is sent to the lower part of the stamping machine 11 by the pneumatic suction cup 409. While the fixed column 406 can drive the moving rod 407 to slide back and forth in the first slide rail 4010, the first slide rail 4010 and the limiting block 5 can drive the limiting baffle 4011 to slide outside the second slide rail 6. When the limiting baffle 4011 moves to both sides of the limiting plate 7, it can be buffered by the buffer damper 10. Then, the above movement is repeated continuously.
[0004] This patent utilizes a pneumatic suction cup to move the sheet metal to the bottom of the stamping machine, which avoids manual loading and improves safety. However, the method of using a pneumatic suction cup to load the sheet metal from top to bottom has certain drawbacks. When the pneumatic suction cup detaches from the sheet metal, there is a certain distance between the sheet metal and the stamping machine. After the sheet metal falls, it will generate a certain vibration, which can easily cause the stamping position of the sheet metal to deviate, directly affecting the processing quality of the sheet metal. It is also necessary for the staff to manually support and confirm the position before the stamping operation, resulting in low loading accuracy. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 This utility model provides a technical solution: a feeding mechanism for a stamping die, including a stacking box 1, which has a front opening and an upper opening structure. A lifting component 2 is fixedly connected to the left side of the stacking box 1, and a feeding plate 3 is fixedly connected to the right side of the stacking box 1. Two feeding components 4 are fixedly connected to the upper surface of the feeding plate 3, and two pushing components 5 are fixedly connected to the upper surface of the feeding plate 3. Two strip grooves are opened on the right side of the feeding plate 3, and guide components 6 are slidably connected to the inner walls of the two strip grooves.
[0023] The lifting component 2 is used to lift the sheet metal and move it onto the feeding tray 3. The feeding component 4 is used to move the sheet metal to the right. The pushing component 5 is used to push the sheet metal out of the feeding tray 3 and move it onto the stamping die. The guiding component 6 is used to guide the sheet metal to prevent it from shifting position.
[0024] Furthermore, the lifting component 2 includes a positioning frame 201. A slide groove is formed on the right side of the positioning frame 201. A first servo motor 202 is fixedly connected to the inner bottom wall of the slide groove. A threaded rod 203 is fixedly connected to the output end of the first servo motor 202. The top end of the threaded rod 203 is rotatably connected to the inner top wall of the slide groove. A transmission block 204 is slidably connected to the inner wall of the slide groove. The transmission block 204 is threadedly connected to the threaded rod 203. A fixing frame 205 is fixedly connected to the right side of the transmission block 204. A first electric push rod 206 is fixedly connected to the inner wall of the fixing frame 205. The output end of the first electric push rod 206 is fixed... A support frame 207 is connected, and a horizontal plate 208 is fixedly connected to the bottom end of the support frame 207. Four pneumatic suction cups 209 are fixedly connected to the lower surface of the horizontal plate 208. After the first servo motor 202 is started, it drives the transmission block 204 to descend through the threaded rod 203 until the four pneumatic suction cups 209 below the horizontal plate 208 contact the material and adsorb the material. At this time, the first servo motor 202 drives the material to rise to the height of the feeding plate 3, and the first electric push rod 206 drives the horizontal plate 208 and the material to move to the position above the feeding plate 3. At this time, the pneumatic suction cups 209 close, and the material falls into the feeding plate 3.
[0025] Furthermore, the feeding assembly 4 includes a second servo motor 401. The front and rear inner walls of the feeding tray 3 are provided with fixing grooves. Four rotating shafts 402 are rotatably connected to the inner bottom wall of the fixing grooves. The output end of the second servo motor 401 is fixedly connected to the top end of any rotating shaft 402. Feeding friction wheels 403 are fixedly connected to the surface of the rotating shaft 402. A transmission sprocket 404 is fixedly connected to the surface of every two adjacent rotating shafts 402. A chain 405 is connected between every two transmission sprockets 404. The front and back sides of the plate can contact the two sets of feeding friction wheels 403 in the feeding tray 3. At this time, the second servo motor 401 starts and can drive the rotating shaft 402 to rotate. Through the transmission sprocket 404 and the chain 405, it can drive the two sets of four feeding friction wheels 403 to rotate synchronously, thereby driving the plate to move to the right.
[0026] Furthermore, the pushing component 5 includes a third servo motor 501, the output end of which is fixedly connected to a circular shaft 502. Rotating grooves are provided on both the front and back of the feeding disc 3. The bottom end of the circular shaft 502 is rotatably connected to the inner bottom wall of the rotating groove, and a pushing plate 503 is fixedly connected to the surface of the circular shaft 502. After the sheet material is separated from the feeding friction wheel 403, it moves to the position of the two pushing plates 503. At this time, the third servo motor 501 starts and drives the pushing plate 503 to rotate through the circular shaft 502. The two pushing plates 503 can drive the sheet material to continue moving to the right until it is separated from the feeding disc 3 and moves onto the stamping die, without the need for manual feeding by the operator.
[0027] Furthermore, the guide assembly 6 includes an extension frame 601, with a guide plate 602 fixedly connected to the upper surface of the extension frame 601. A strip frame 603 is fixedly connected to the lower surface of the feed tray 3 at positions corresponding to the two strip slots. The strip frame 603 has an open structure at the top. A second electric push rod 604 is fixedly connected to the left inner wall of the strip frame 603. A connecting plate 605 is fixedly connected to the output end of the second electric push rod 604. The connecting plate 605 is slidably connected to the inner bottom wall of the strip frame 603, and extends into the interior of the strip slot and is fixedly connected to the left side of the extension frame 601. After the second electric push rod 604 is started, it can drive the extension frame 601 to move to the right through the connecting plate 605, and at the same time drive the guide plate 602 to extend onto the stamping die. At this time, the sheet metal is pushed to the right by the push assembly 5 and moves onto the stamping die. The front and rear positions of the sheet metal are blocked by the guide plate 602, thereby ensuring that the sheet metal can move to the accurate position of the stamping die.
[0028] Working principle: First, the boards are stacked in the stacking bin 1. When feeding is required, the first servo motor 202 is turned on. The first servo motor 202 drives the transmission block 204 to descend through the threaded rod 203, so that the four pneumatic suction cups 209 under the horizontal plate 208 come into contact with the boards. After the pneumatic suction cups 209 pick up the boards, the first servo motor 202 drives the horizontal plate 208 to rise to the height of the feeding plate 3. At the same time, the first electric push rod 206 drives the support frame 207 to move to the right until the boards move to the position above the feeding plate 3. At this time, the pneumatic suction cups 209 are turned off, and the boards fall into the feeding plate 3. At the same time, the two second servo motors 401 are started, and the transmission sprockets 404 and chains 4 05 drives four rotating shafts 402 to rotate synchronously, thereby driving the sheet metal to move to the right through two sets of feeding friction wheels 403 until the sheet metal disengages from the feeding friction wheels 403. At this time, the second electric push rod 604 starts and drives the extension frame 601 to move to the right through the connecting plate 605. The extension frame 601 drives the guide plate 602 to extend to the stamping die position. At the same time, the third servo motor 501 starts and drives the push plate 503 to rotate towards the middle position of the feed plate 3 through the circular shaft 502. The two push plates 503 can drive the sheet metal to continue to move to the right until the sheet metal disengages from the feed plate 3 and moves onto the stamping die, completing the automatic feeding operation of the sheet metal, and the position is more accurate.
