When the two dust suction plates 35 are displaced, the stamping parts at the upper end of the lower template 12 are pushed to be displaced, so that the stamping parts pass through the lower end of the air outlet plate 11 and fall to the upper end of the receiving platform 6, and the convex plate at one end of the receiving platform 6 blocks the stamping parts to prevent the stamping parts from falling from the upper end of the receiving platform 6 to the ground.

[0054] The working principle of the present invention is as follows: when the staff uses the device to perform stamping operations on metal sheets, the staff places the metal sheets on the upper end of the device body 1, and then starts the drive motor 17 through the control panel 2, and the drive motor 17 drives the drive shaft 18 to rotate clockwise, and the outer wall of the drive shaft 18 is threadedly connected with the inner wall of the first protrusion 20, so the first protrusion 20 moves toward the stamping bin 5, thereby driving the push plate 19 to move toward the stamping bin 5, and then driving the metal sheets to move toward the stamping bin 5;

[0055] When the drive shaft 18 rotates, because the drive shaft 18 is connected to one end of the installation shaft 28 through a synchronous belt, one end of the installation shaft 28 rotates, but the second one-way bearing 29 is provided so that the other end of the installation shaft 28 does not rotate;

[0056] When the push plate 19 is displaced, the second convex plate 21 is driven to be displaced, and the inner wall of the second convex plate 21 is threadedly connected to the outer wall of a group of limit shafts 22, so a group of limit shafts 22 rotate, and the two groups of limit shafts 22 are connected by a synchronous belt, so the two groups of limit shafts 22 rotate synchronously, and the outer walls of the two groups of limit shafts 22 are threadedly connected to the inner walls of the two groups of limit plates 23, respectively, so the two groups of limit plates 23 are displaced, thereby driving one end of the metal sheet to be displaced, and providing auxiliary support for one end of the metal sheet to prevent one end of the metal sheet from falling into the stamping bin 5, causing the metal sheet to be in an inclined state, affecting the subsequent stamping operation;

[0057] When the two sets of limit shafts 22 rotate, and the two sets of limit shafts 22 are connected to one end of the transmission shaft 24 through a synchronous belt, one end of the transmission shaft 24 rotates, but the setting of the first one-way bearing 25 prevents the other end of the transmission shaft 24 from rotating;

[0058] After the metal sheet is suspended on the upper end of the punching bin 5, the two sets of limit plates 23 move into the interior of the equipment body 1, release the auxiliary support on one end of the metal sheet, and the metal sheet falls into the punching bin 5, and then falls to the upper end of the lower template 12, and then the drive motor 17 is turned off and the hydraulic pump 7 is started;

[0059] When the hydraulic pump 7 is started, the hydraulic oil enters the first hydraulic cylinder 9 and the second hydraulic cylinder 14 through the first hydraulic pipe 8 and the second hydraulic pipe 13 respectively, thereby driving the first telescopic column 10 and the second telescopic column 15 to move, and then driving the lower template 12 and the upper template 16 to move, and the upper template 16 and the lower template 12 cooperate to perform stamping operations on the metal plate;

[0060] When the stamping operation is completed, the upper template 16 and the lower template 12 are reset, and the stamping part moves downward with the lower template 12, and then the staff starts the drive motor 17, and the drive motor 17 drives the drive shaft 18 to rotate counterclockwise, thereby driving the push plate 19 and the two sets of limit plates 23 to reset, and the other end of the transmission shaft 24 rotates, and the other end of the transmission shaft 24 is connected to the two sets of first linkage shafts 26 through a synchronous belt, so the two sets of first linkage shafts 26 rotate, and the outer walls of the two sets of first linkage shafts 26 are threadedly connected to the inner walls of the two ends of the first dust suction plate 27, and the outer wall thread grooves of the two sets of first linkage shafts 26 are reciprocating thread grooves, so the first dust suction plate 27 moves back and forth;

[0061] When the driving shaft 18 rotates counterclockwise, the installation shaft 28 is driven to rotate, and the installation shaft 28 is connected to a set of second linkage shafts 34 through a synchronous belt, so a set of second linkage shafts 34 rotates, and the two sets of second linkage shafts 34 are connected through a synchronous belt, and the two sets of second linkage shafts 34 rotate synchronously, and the outer walls of the two sets of second linkage shafts 34 are respectively threadedly connected to the inner walls of the two ends of the second dust collecting plate 35, and the thread grooves on the outer walls of the two sets of second linkage shafts 34 are reciprocating thread grooves, so the second dust collecting plate 35 moves back and forth;

[0062] When the second dust collecting plate 35 is displaced, the stamping part on the upper end of the lower template 12 is pushed to be displaced, so that the stamping part passes through the lower end of the air outlet plate 11 and falls to the upper end of the receiving platform 6, and the convex plate at one end of the receiving platform 6 blocks the stamping part to prevent the stamping part from falling from the upper end of the receiving platform 6 to the ground;

[0063] When the mounting shaft 28 rotates, the fan 31 is driven to rotate, so that airflow is generated inside the bellows 30, and the airflow is transmitted to the air outlet plate 11 through the air outlet pipe 38. When the stamping parts pass through the lower end of the air outlet plate 11, the airflow cools the stamping parts, thereby improving the stamping processing efficiency;

[0064] When airflow is generated inside the bellows 30, negative pressure is generated at the air inlet of the bellows 30, and the negative pressure is transmitted to the dust collecting box 33 through the suction plate 32, and the suction force is transmitted to the first dust suction plate 27 and the second dust suction plate 35 through the first dust suction pipe 37 and the second dust suction pipe 36. At the same time, the first dust suction plate 27 and the second dust suction plate 35 move back and forth, so the first dust suction plate 27 and the second dust suction plate 35 respectively absorb the iron filings remaining on the surface of the upper template 16 and the lower template 12 to prevent the iron filings from remaining on the surface of the upper template 16 or the lower template 12 and affecting the quality of the next group of stamping workpieces.

[0065] The present invention is provided with a bellows 30, a dust collecting box 33, a first dust collecting plate 27 and a second dust collecting plate 35. The first dust collecting plate 27 and the second dust collecting plate 35 respectively absorb the iron filings remaining on the surface of the upper template 16 and the lower template 12 to prevent the iron filings from remaining on the surface of the upper template 16 or the lower template 12 and affecting the quality of the next group of stamping workpieces.
