While punching, the output end of the motor drives the synchronous wheel 1 to rotate, and the synchronous wheel 2 also rotates therewith, so that the roller also rotates together, and the sheet material is sent forward while being punched.

Therefore, a fixed plate is installed on one side of the base, and the interior of the fixed plate is slidably equipped with telescopic rod 2. The limit rod moves back and forth through the connecting rod to repeatedly push the telescopic rod 2 downward, so that the top of the telescopic rod 2 repeatedly knocks and vibrates the collection frame to make the internal corners fall off, making cleaning more convenient.

[0018] 3. The present invention uses the setting of structures such as the positioning plate and the spring 1. Since the size of the cut sheet material itself is not necessarily regular, it may be offset when being pushed. Therefore, a positioning plate is slidably installed inside the bracket, and the sheet material is placed inside the bracket. Since a spring 1 is provided on one side of the positioning plate, the positioning plate will always be close to the sheet material and push the sheet material to one side so that it will not be offset, and the practical effect is better.

Through the arrangement of the motor 27 and the roller 34 and other structures, the output end of the motor 27 drives the rocker 26 to rotate, and the rocker 26 drives the connecting plate 24 to move up and down through the connecting rod 25, so that the connecting plate 24 drives the two push rods 23 to move up and down for punching. While punching, the output end of the motor 27 drives the synchronous wheel 1 35 to rotate, and the synchronous wheel 2 29 also rotates therewith, so that the roller 34 also rotates together, and the sheet material is punched while being sent forward, and the punching of corners and cutting are carried out at the same time, so that there is no deviation during punching, which reduces the cost.

[0031] See also Figure 2The bottom of the bracket 22 is fixedly connected to the collection frame by screws, one side of the connecting rod 25 is fixedly connected to the limiting rod by screws, one side of the base 33 is fixedly connected to the fixing plate 19 by screws, the fixing plate 19 is provided with a through slot inside, the inside of the through slot is slidably connected to the telescopic rod 20, the top of the telescopic rod 20 is inclined, one end of the limiting rod is slidably connected to the top of the telescopic rod 20, the bottom of the through slot is welded with a spring 21, the other end of the spring 21 is welded to the outer circumference of the telescopic rod 20, through the telescopic rod 20 and the collection frame With the arrangement of structures such as frames, when the edges and corners punched by the punching column 2 fall into the interior of the collection frame, although the interior of the collection frame is inclined, since the punched parts are all metal sheets, the edges and corners may not fall off. Therefore, a fixed plate 19 is installed on one side of the base 33, and a telescopic rod 20 is slidably assembled inside the fixed plate 19. The limit rod moves back and forth through the connecting rod 25 to repeatedly push the telescopic rod 20 downward, so that the top of the telescopic rod 20 repeatedly knocks and vibrates the collection frame to make the internal edges and corners fall off, making cleaning more convenient.

[0032] See also Figure 1 A sliding groove is provided at the bottom of the connecting plate 24, and the connecting rod 25 is slidably connected inside the sliding groove.

[0033] See also Figure 6 A groove is provided inside the bracket 22, and the push plate 8 is slidably connected inside the groove. Four symmetrically arranged circular grooves are provided inside the bracket 22, and the telescopic rod 9 is fixedly connected to the bottom wall of the circular groove by screws.

[0034] See also Figure 6 Four symmetrically arranged punching holes 10 are formed inside the bracket 22 , and the four punching columns 2 are slidably connected inside the punching holes 10 .

[0035] See also Figure 3 A T-shaped slot 18 is provided inside the square plate 15 2 , and the pressing block 17 is slidably connected inside the T-shaped slot 18 .

[0036] See also Figure 8 Four symmetrically arranged straight grooves are provided inside the straight plate 1, and the top of the punching column 2 is slidably connected inside the straight grooves.

[0037] The specific implementation process is as follows: the output end of the motor 27 drives the rocker 26 to rotate, and the rocker 26 drives the connecting rod 25 to rotate. Since the other end of the connecting rod 25 is slidably connected to the inside of the connecting plate 24, the connecting plate 24 will move up and down, so that the connecting plate 24 simultaneously drives the two push rods 23 to move up and down for punching. While punching, the output end of the motor 27 drives the synchronous wheel 1 35 to rotate, and the synchronous wheel 1 35 drives the synchronous wheel 2 29 to rotate through the synchronous belt 2 31. The synchronous wheel 2 29 drives the semi-annular gear 4 to rotate through the synchronous belt 1 30. The semi-annular gear 4 drives the one-way shaft gear 5 to rotate indirectly, so that the roller 34 also rotates indirectly together, and the sheet material is clamped between the roller 34 and the bracket 22 and moves forward together, and then stamping is performed, and the punching of corners and cutting are performed simultaneously, so that there will be no Offset, when the corners punched by the punching column 2 fall into the inside of the collection frame, although the inside of the collection frame is inclined, since the punched parts are all metal sheets, the corners may not fall off. Therefore, a fixed plate 19 is installed on one side of the base 33, and a telescopic rod 20 is slidably installed inside the fixed plate 19. The limit rod moves back and forth through the connecting rod 25 to push the telescopic rod 20 downward repeatedly, so that the top of the telescopic rod 20 repeatedly knocks and vibrates the collection frame to make the internal corners fall off, making cleaning more convenient, and an inlet pipe 13 and an outlet pipe 14 are arranged inside the bracket 22. Since friction is generated during punching, the mold temperature will be too high, resulting in more serious wear. Therefore, an inlet and outlet pipe 14 is provided inside the bracket 22 to cool the bracket 22 and extend its service life.

[0038] Embodiment 2:

[0039] See also Figure 7 A slide groove is provided inside the bracket 22, and a positioning plate 11 is slidably connected inside the slide groove. Several evenly arranged springs 12 are welded on one side of the bracket 22, and the other end of the spring 12 is welded to one side of the positioning plate 11. Through the setting of the positioning plate 11 and the spring 12 and other structures, since the size of the cut sheet material itself is not necessarily regular, it may be offset when pushed. Therefore, a positioning plate 11 is slidably assembled inside the bracket 22, and the sheet material is placed in the bracket 22. Since a spring 12 is provided on one side of the positioning plate 11, the positioning plate 11 will always be close to the sheet material and push the sheet material to one side, so that it will not be offset, and the practical effect is better.

[0040] The specific implementation process is as follows: place the sheet material from one side of the bracket 22 into the bottom of the roller 34. Since the width of the sheet material itself may have errors, the punching will be offset when the sheet material slides forward. Therefore, a positioning plate 11 is slidably installed on one side of the bracket 22. The sheet material is squeezed by the positioning plate 11 so that the sheet material is tightly attached to one side of the bracket 22 without offset, and can be adjusted according to the width of the sheet material, so that the practical effect is better.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
