[0037] like Figures 1 to 3As shown, in one embodiment, a punching mechanism 1 includes a base 10 and a punching assembly 20. The base 10 is provided with a die groove 13, which is used to carry a die 30. The punching assembly 20 includes a pressing plate 21, a push seat 22, a top seat 23, an elastic member 24 and two punching blocks 25. The pressing plate 21 is slidably arranged on the base 10, the push seat 22 is arranged on the pressing plate 21, one end of the top seat 23 is penetrated by the pressing plate 21, the elastic member 24 is sleeved on the top seat 23, and the elastic member 24 pushes the top seat 23 and the pressing plate 21 respectively. The two punching blocks 25 are respectively slidably connected to the push seat 22 and the top seat 23, and the two punching blocks 25 have an angle with respect to the sliding direction of the top seat 23. When the pressing plate 21 drives the push seat 22 and the top seat 23 to move downward at the same time, the top seat 23 abuts against the base 10 to press the workpiece, and the push seat 22 simultaneously pushes the two punching blocks 25 to punch the two sides of the workpiece at the same time.

[0038] It should be noted that the base 10 has a U-shaped structure, with corresponding push grooves and top grooves extending vertically on both sides, which are interconnected. The push grooves extend through the upper and lower surfaces of the base 10, while the top grooves extend from the upper surface of the base 10 to the inner bottom wall of the base 10. Furthermore, the two ends of the pressure plate 21 slide within the push grooves and top grooves, respectively, allowing the pressure plate 21 to move up and down relative to the base 10. Furthermore, a push seat 22 is provided on the side of the pressure plate 21 facing the base 10, and the push seat 22 slides within the push grooves. When the pressure plate 21 slides up and down, it drives the push seat 22 to move up and down relative to the base 10. Furthermore, the pressure plate 21 has two perforations, both located at the end of the pressure plate 21 away from the push seat 22. One end of the top seat 23 is provided through the two perforations, while the other end of the top seat 23 away from the pressure plate 21 slides within the top groove. The push seat 22 and the top seat 23 are located at opposite ends of the pressure plate 21. Furthermore, two adjacent side surfaces of one punching block 25 are slidably connected to one side surface of the push seat 22 and the top seat 23, respectively, and two adjacent side surfaces of the other punching block 25 are slidably connected to the other side surfaces of the push seat 22 and the top seat 23, respectively. When the push seat 22 approaches the top seat 23, the two punching blocks 25 are pushed to slide outward toward the two side surfaces of the top seat 23. Furthermore, the elastic member 24 is a spring structure, and the elastic member 24 is sleeved on the top seat 23. The elastic member 24 pushes the pressure plate 21 and the top seat 23 respectively. In this way, when the pressure plate 21 moves downward, the pressure plate 21 will simultaneously drive the push seat 22 and the top seat 23 to slide downward along the push groove and the top groove, so that the top seat 23 can slide close to the inner bottom wall of the base 10, so that the top seat 23 and the base 10 can jointly press the workpiece. Since an elastic member 24 is sleeved on one end of the top seat 23 facing the pressure plate 21, after the pressure plate 21 drives the top seat 23 to abut against the base 10, the pressure plate 21 can continue to drive the push seat 22 to slide downward, thereby causing the push seat 22 to simultaneously push the two punching blocks 25 to slide outward along the two sides of the top seat 23, so that the two punching blocks 25 punch the two side surfaces of the workpiece at the same time. In this way, the punching process of the right-angle structure workpiece can be completed quickly, thereby improving production efficiency and reducing production costs. Furthermore, when the pressure plate 21 drives the push seat 22 and the top seat 23 to move upward, the push block 222 on the push seat 22 will drive the two punching blocks 25 to move upward. At the same time, since the top seat 23 is provided with an elastic member 24, when the pressure plate 21 rises, the elastic member 24 pushes the top block 232 on the top plate 231 to keep it in contact with the base 10, thereby causing the top block 232 to pull the two punching blocks 25 downward. In this way, the push block 22 and the top block 232 move in two opposite directions, respectively, to pull the two punching blocks 25 closer to each other, thereby causing the two punching blocks 25 to move away from the two side edges of the workpiece.

[0039] like Figure 5As shown, in one embodiment, the push seat 22 includes a push plate 221 and a push block 222. The push plate 221 is arranged on the pressure plate 21, and the push block 222 is arranged on one end of the push plate 221 close to the pressure plate 21. The two sides of the push block 222 away from the pressure plate 21 are respectively slidably connected to the two punching blocks 25.

[0040] It should be noted that the push plate 221 is disposed on the end of the pressure plate 21 away from the top seat 23, and the portion of the push plate 221 away from the pressure plate 21 slides in the push groove. The push block 222 is disposed on the side surface of the push plate 221 facing the top seat 23, and the push block 222 is located in the top groove. Furthermore, two cams are disposed on the end of the push block 222 away from the pressure plate 21. The angle between the two cams is 90 degrees, and the angle between the two cams is toward the top block 232. Furthermore, grooves are formed on one side of each of the two punching blocks 25, and the two grooves are respectively engaged with the two cams in a one-to-one correspondence. In this way, the two punching blocks 25 can slide apart or slide closer to each other at a 90-degree angle toward the end of the push block 222 away from the pressure plate 21.

[0041] like Figure 6 As shown, in one embodiment, the top seat 23 includes a top plate 231 and a top block 232. One end of the top plate 231 is passed through the pressure plate 21, and the top block 232 is arranged on the end of the top plate 231 away from the pressure plate 21. The top block 232 is slidably connected to the two punching blocks 25 on the two side surfaces facing the pressure plate 21, and the elastic member 24 is sleeved on the top plate 231, and the elastic member 24 pushes the top plate 231 and the pressure plate 21 respectively.

[0042] It should be noted that the top plate 231 includes an angle plate and two guide posts. The angle plate is shaped like a right triangle. One end of each guide post is located on one end of the angle plate's hypotenuse, while the other ends of the two guide posts extend through two holes in the pressure plate 21 and extend from the other side of the pressure plate 21. A retaining plate is provided on the end of each guide post extending from the side of the pressure plate 21 away from the angle plate. The retaining plate prevents the angle plate from completely sliding off the pressure plate 21. Furthermore, two elastic members 24 are provided. Each elastic member 24 is respectively mounted on the two guide posts and positioned between the angle plate and the pressure plate 21. The two elastic members 24 push against the angle plate and the pressure plate 21, respectively, to keep the angle plate away from the pressure plate 21. Furthermore, the top block 232 is shaped like a square. The top block 232 is located on the end of the angle plate away from the two guide posts, and the right-angled end of the top block 232 overlaps with the right-angled end of the angle plate. Two chute slots are defined on the right-angled end of the top block 232, away from the right-angled end of the angle plate. The angle between the two chute slots is 90 degrees, and the angle between the two chute slots faces the push block 222. Furthermore, the two punching blocks 25 are each provided with a slide rail on one side adjacent to the chute slots, and both slide rails engage with the two chute slots. Thus, when the push block 222 is moved downward, it forces the two punching blocks 25 to slide toward each side along the right-angled end of the top block 232, allowing the two punching blocks 25 to punch holes on both sides of the workpiece.

[0043] like Figure 3 、 Figures 7 to 10 As shown, in one embodiment, the punching block 25 includes a punch block 251 and a punch 252. The two adjacent side surfaces of the punch block 251 are slidingly connected to the push block 222 and the top block 232 respectively. A rib groove 2511 and a circular groove 2512 are provided on the punch block 251, and the rib groove 2511 and the circular groove 2512 are connected to each other. The punch 252 is clamped with the rib groove 2511 and the circular groove 2512, and the punch 252 is used to punch the workpiece.

[0044] It should be noted that a ribbed groove 2511 and a circular groove 2512 are respectively formed on the end of the punch 251 away from the cam. The circular groove 2512 is formed at the farthest end of the punch 251 away from the chute. The ribbed groove 2511 is formed on the side of the circular groove 2512 facing the chute. The ribbed groove 2511 and the circular groove 2512 are interconnected. The punch 252 is located in both the ribbed groove 2511 and the circular groove 2512. It should be noted that the circumscribed circle diameter of the ribbed groove 2511 is larger than the diameter of the circular groove 2512. When one end of the punch 252 is located in the ribbed groove 2511, the circular groove 2512 can clamp one end of the punch 252 and allow the other end of the punch 252 to extend from the circular groove 2512. Furthermore, a screw hole 2513 is formed on the punch 251, extending from the outer wall of the punch 251 into the ribbed groove 2511. When the punch 252 is inserted into the rib groove 2511 , a screw is screwed into the punch 252 through the screw hole 2513 , so that the punch 252 is detachably fixed to the punch block 251 .

[0045] like Figure 10 As shown, in one embodiment, one end of the punch 252 is a prismatic structure that is adapted to the rib groove 2511, and the other end of the punch 252 is a cylindrical structure that is adapted to the circular groove 2512. When the prismatic structure of the punch 252 is stuck in the rib groove 2511, the punch 252 cannot rotate and cannot slide off the punch block 251, and the other end of the punch 252 extends from the circular groove 2512, so that the punch 252 punches a circular hole in the workpiece.

[0046] In one embodiment, one end of the punch 252 is a prismatic structure that fits within the rib groove 2511, while the other end of the punch 252 is an elliptical structure. When the prismatic structure of the punch 252 is engaged within the rib groove 2511, the punch 252 cannot rotate or slide out of the punch block 251, while the other end of the punch 252 extends from the circular groove 2512, allowing the punch 252 to punch an elliptical hole in the workpiece. Furthermore, the engagement between the punch 252 and the rib groove 2511 can be adjusted by rotating to adjust the angle of the elliptical structure, thereby allowing the punch 252 to punch an elliptical hole at a fixed angle in the workpiece.

[0047] In one embodiment, two circular punches 252 are simultaneously mounted on the two punch blocks 251 to punch two circular holes on both sides of the workpiece.

[0048] In one embodiment, two punches 252 with elliptical structures are simultaneously mounted on the two punch blocks 251 to punch two elliptical holes on both sides of the workpiece.

[0049] In one embodiment, two punch blocks 251 are simultaneously mounted with an elliptical punch 252 and a circular punch 252 to punch an elliptical hole and a circular hole on two sides of the workpiece, respectively.

[0050] It should be noted that the punch block 251 can be flexibly replaced with punches 252 of various shapes according to production requirements to meet production diversification.

[0051] like Figure 1 、 Figure 5 As shown, in one embodiment, the push seat 22 further includes a shear block 223 . The shear block 223 is disposed on one end of the push plate 221 away from the pressing plate 21 . The shear block 223 is used to shear the workpiece.

[0052] It should be noted that one end of the shear block 223 is located at the end of the pressure plate 21 away from the two perforations, while the other end of the shear block 223 slides within the push groove. Both the shear block 223 and the angle plate are located on the side of the pressure plate 21 facing the base 10. The shear block 223 also tends to be a triangular structure, with the right-angled end of the shear block 223 facing the base 10. The pressure plate 21 drives the shear plate to shear the workpiece on the base 10.

[0053] It should be noted that the inner bottom of the base 10 is a right-angle structure, and the die groove 13 is opened at the inner bottom of the base 10, so that the die groove 13 is also a right-angle shape, and the die groove 13 is located at the end of the base 10 close to the shear plate. When the die 30 is installed in the die groove 13, the die 30 will be on the same horizontal line as the other end of the base 10. In this way, when the workpiece is placed on the inner bottom of the base 10 and the workpiece extends from the two opposite sides of the push seat 22 and the top seat 23 respectively, when the pressure plate 21 simultaneously drives the push seat 22 and the top seat 23 to move downward, the clamping plate and the top block 232 on the top seat 23 will first press the workpiece, and at the same time, the push block 222 on the push seat 22 will push the two punching blocks 25 to punch the workpiece. At the same time, the push seat 22 drives the shear block 223 to shear off the workpiece extending from one side of the push seat 22. Furthermore, when a punching process is completed on the workpiece, the pressure plate 21 will drive the shear block 223, the push block 222 and the top block 232 to slide upward, so that the workpiece can continue to be dragged from the side of the top seat 23 to the side of the push seat 22, which makes the external push seat 22 away from the side of the top seat 23 where the punching is completed, and then move downward through the pressure plate 21, so that the top seat 23 presses the workpiece downward while the push plate 221 drives the push block 222 to push the two punching blocks 25 along the two sides of the top block 232 to punch the two sides of the workpiece. At the same time, the push plate 221 also drives the shear block 223 to shear off the workpiece where the punching has been completed. In this way, the above actions are repeated continuously, and the punching and shearing processes can be completed automatically and continuously to improve production efficiency and reduce production costs.

[0054] like Figure 4 As shown, in one embodiment, a through hole 11 is further defined on the base 10 , and the through hole 11 extends from the outer wall of the base 10 to the mold cavity 13 .

[0055] It should be noted that the through hole 11 extends from the side surface of the base 10 away from the shear block 223 to the side wall of the mold groove 13, so that when the mold 30 is placed in the mold groove 13, it can be screwed together by screws to prevent the mold 30 from loosening and shifting during the punching process.

[0056] like Figures 1 to 4 As shown, in one embodiment, a waste hole 12 is further provided on the base 10 , and the waste hole 12 is communicated with the mold cavity 13 .

[0057] It should be noted that there are two waste holes 12, which extend from the two opposite outer walls of the base 10 to the two ends of the die groove 13 respectively, and are connected to the punching position of the mold 30, so that the waste after the punch 252 punches the workpiece can be discharged from the two waste holes 12 respectively.

[0058] like Figures 1 to 3 As shown, in one embodiment, a plurality of connection holes 211 are provided on one end of the pressing plate 21 away from the top seat, and each connection hole 211 is used to connect a driving device, for example, the driving device is a cylinder or a punch press.

[0059] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
