[0026] like Figures 1-6 As shown, this invention illustrates an adjustable metal casting punching device according to one embodiment of the present invention. It includes a punching table 1, with a support frame 2 fixedly connected to the top of the punching table 1. A punching machine 201 is fixedly connected to the top of the support frame 2. A sliding frame 502 is provided on the upper surface of the punching table 1. A sliding table 505 is slidably connected to the inner wall of the sliding frame 502. A clamping plate 506 is rotatably connected to the top of the sliding table 505. A lead screw 504 is threadedly connected to the inner wall of the sliding frame 502. The outer wall of the lead screw 504... The inner wall of the sliding table 505 is threadedly connected to the stamping table 1. The end of the stamping table 1 away from the sliding table 505 is fixedly connected to the connecting plate 4. The outer wall of the connecting plate 4 is fixedly connected to the connecting shaft 401. One end of the connecting shaft 401 is fixedly connected to the positioning pin 5. The outer wall of the positioning pin 5 is sleeved with the replacement mold 501. The end of the replacement mold 501 away from the positioning pin 5 is sleeved with the outer wall of the clamping plate 506. The outer wall of the connecting shaft 401 is rotatably connected to the ratchet 402. The end of the ratchet 402 away from the connecting plate 4 is provided with the clamping assembly 6.

[0027] It should be noted that the top of the sliding table 505 is provided with two fixing blocks. One side of the fixing block is provided with a shaft. The outer wall of one of the shafts is rotatably connected to the inner wall of the clamping plate 506. The other end of the clamping plate 506 is an open ring. The operator can unfold the sliding table 505 by flipping one end of the clamping plate 506. A concave space will be formed in the middle of the sliding table 505. The replacement mold 501 can be replaced or taken out through this space. Metal parts can also be installed. The other shaft is used to lock the open ring of the clamping plate 506. By locking the open ring with the shaft, the clamping plate 506 is laterally locked, and the concave space is also closed.

[0028] For example, such as Figure 3 As shown, a stamping rod 202 is slidably connected to the output end of the stamping machine 201, and a stamping plate 3 is fixedly connected to the bottom end of the stamping rod 202.

[0029] It should be noted that the output end of the stamping machine 201 is connected to the stamping rod 202, and the bottom end of the stamping rod 202 is fixedly connected to the stamping plate 3. When the operator needs to perform a punching operation, the stamping plate 3 pushes the stamping rod 202 through the output end, and the stamping rod 202 is forced to push the stamping plate 3 to perform the punching.

[0030] For example, such as Figure 4 As shown, a plurality of guide rods 101 are fixedly connected around the upper surface of the stamping table 1, near the end of the support frame 2. The outer wall of the guide rods 101 is slidably connected to the inner wall of the stamping plate 3. A stamping die 301 is fixedly connected to the bottom of the stamping plate 3. A plurality of buffer rods 302 are slidably connected to the inner wall of the stamping plate 3, near the end of the stamping die 301. A pressure plate 303 is fixedly connected to the bottom end of the plurality of buffer rods 302.

[0031] It should be noted that the top periphery of the stamping plate 3 is provided with multiple sliding holes, which are slidably connected to the outer wall of the guide rod 101. The guide rod 101 is used to stably guide the stamping of the stamping plate 3. The inner wall of the stamping plate 3 is provided with multiple sliding grooves, and the inner wall of the pressing plate 303 is provided with multiple round holes corresponding to the stamping die 301. When the stamping plate 3 pushes the pressing plate 303 and the stamping die 301 to punch, the pressing plate 303 will first contact the top of the metal part and squeeze and fix it. The pressing plate 303 is resisted and causes the buffer rod 302 to be stationary on the top of the metal part. The stamping plate 3 drives the stamping die 301 to press down, and the sliding round hole of the stamping die 301 punches the metal part and punches.

[0032] For example, such as Figure 4 As shown, a push rod 304 is fixedly connected to the outer wall of the pressing plate 303, and a pawl 403 is rotatably connected to the outer wall of the connecting plate 4 at the end away from the connecting shaft 401. The outer wall of the pawl 403 meshes with the inner wall of the ratchet 402. A spring 404 is fixedly connected to the top of the pawl 403, and a limiting plate 405 is fixedly connected to the upper surface of the connecting plate 4. The bottom end of the limiting plate 405 is fixedly connected to the top end of the spring 404.

[0033] It should be noted that the connecting shaft 401 is fixedly installed in the middle of the outer wall of the limiting plate 405. The ratchet 402 is rotatably connected to the outer wall of the connecting shaft 401. At the same time, one side of the ratchet 402 contacts the bottom of the push rod 304. When the stamping die 301 stamps, the pressing plate 303 drives the push rod 304 to press down. The push rod 304 presses down one side of the ratchet 402, causing the ratchet 402 to rotate at a fixed angle. The other side of the ratchet 402 slides away from the pawl 403. The pawl 403 is pushed upward by the force of the ratchet 402 to compress the spring 404. When the punching is finished, the push rod 304 slides upward, and the spring 404 pushes the pawl 403 back. The pawl 403 is forced back to its original position and continues to engage with the ratchet 402, thereby realizing the self-locking of the ratchet 402.

[0034] For example, such as Figure 5 As shown, two sliding rods 503 are symmetrically fixedly connected to the inner wall of the sliding frame 502 at the end away from the lead screw 504. The outer wall of the sliding rod 503 is slidably connected to the inner wall of the sliding table 505.

[0035] It should be noted that the sliding rod 503 is symmetrically and fixedly connected to the inner wall of the sliding frame 502. The inner wall of the sliding frame 502 is provided with a transverse sliding groove. The bottom of the sliding table 505 is provided with a sliding strip. The sliding table 505 is slidably connected to the inner wall of the sliding groove. A knob is provided at one end of the lead screw 504. The operator can rotate the knob to drive the lead screw 504 to rotate. The rotation of the lead screw 504 pushes the sliding table 505 to slide through the threaded connection. The sliding table 505 achieves stable sliding inside the sliding frame 502 through the sliding strip and the sliding rod 503.

[0036] For example, such as Figure 6 As shown, the clamping assembly 6 includes a clamping disc 601 fixedly connected to the outer wall of the ratchet 402. The inner wall of the clamping disc 601 is slidably connected to the outer wall of the connecting shaft 401. Two sliding grooves 604 are symmetrically arranged on the inner wall of the clamping disc 601. Two sliding clamping blocks 603 are slidably connected to the inner wall of the sliding grooves 604. A lead screw 602 is threadedly connected to the inner wall of the two sliding clamping blocks 603. The outer wall of the lead screw 602 is rotatably connected to the inner wall of the sliding groove 604.

[0037] It should be noted that the surface of the lead screw 602 is provided with threads at both ends that are opposite to each other. Each thread is connected to a sliding clamping block 603. The sliding clamping block 603 is composed of a sliding block and a clamping block. The sliding block is slidably connected to the inner wall of the sliding groove 604. The inner wall of the sliding block is threadedly connected to the lead screw 602. After the operator rotates the lead screw 602, the lead screw 602 pushes multiple sliding clamping blocks 603 to slide synchronously in opposite directions through multiple threads. When clamping, one inner wall of the metal part needs to be sleeved on the outer wall of the clamping block. When multiple sliding clamping blocks 603 slide synchronously in opposite directions, the clamping block will clamp from the inner wall of the metal part, thereby fixing the metal part.

[0038] The specific operation is as follows: the operator can quickly change the replacement mold 501 by rotating the lead screw 504. When the lead screw 504 rotates, it pushes the sliding table 505 along the outer wall of the sliding rod 503 through the threaded connection. The sliding table 505 then drives the clamping plate 506 to slide on the inner wall of the sliding frame 502. When the clamping plate 506 slides away from one end of the replacement mold 501, the operator can flip the clamping plate 506. After the clamping plate 506 is flipped, sliding space will be freed up. At this time, the operator can take out the replacement mold 501 through the sliding space. After taking it out, a replacement mold 501 of a different size is used for pressing holes. During installation, the other end of the replacement mold 501 needs to be sleeved on the outer wall of the positioning pin 5 for positioning and support. When the replacement mold 501 is supported... After fixing, the operator needs to attach the metal part to the outer wall of the replacement mold 501. During the attachment process, the inner wall of one end of the metal part needs to be aligned with the outer wall of multiple sliding clamps 603. Then, the operator needs to manually rotate multiple lead screws 602. After rotation, the lead screws 602 will push the multiple sliding clamps 603 to slide on the inner wall of the sliding groove 604 through the threaded connection. The multiple sliding clamps 603 clamp and fix one end of the metal part. After clamping, the operator needs to rotate the lead screw 504 in the opposite direction, so that the sliding table 505 slides in the opposite direction on the inner wall of the sliding frame 502. Then, the sliding table 505 drives the clamping plate 506 to slide towards one end of the new replacement mold 501, and continues to clamp and fix one end of the replacement mold 501 through sliding.

[0039] After the metal parts are installed and secured, the operator needs to start the stamping machine 201. The stamping machine 201 pushes the stamping rod 202 and the stamping plate 3 through the output end. The stamping plate 3 slides downward along the outer wall of multiple guide rods 101 to stamp. At the same time, the stamping plate 3 presses down on the stamping die 301 and the pressing plate 303. When the pressing plate 303 contacts the top of the metal part, the pressing plate 303 is resisted by the metal part and pushes the buffer rod 302 in the opposite direction. The buffer rod 302 and the pressing plate 303 press against the top of the metal part. At this time, the stamping plate 3 pushes the stamping die 301 to slide on the outer wall of the buffer rod 302, and punches holes in the metal part through the stamping die 301. At the same time, the pressing plate 303 drives the push rod 201 to push the metal part during stamping. When rod 304 slides downward, push rod 304 pushes one side of ratchet 402, causing ratchet 402 to rotate at a small angle. At this time, ratchet 402 drives clamping plate 601 to rotate, and clamping plate 601 drives the clamped metal part to rotate. When pressing plate 303 finishes one round of stamping and rises, pressing plate 303 drives push rod 304 to leave ratchet 402. The other side of ratchet 402 is self-locked by pawl 403. At the same time, the top of pawl 403 resists ratchet 402 through spring 404. In this way, each round of stamping by stamping machine 201 will drive the metal part to rotate at an equal angle through ratchet 402. Through multiple rounds of rotating stamping, the full punching operation on the outer wall of the metal part is achieved.
