[0024] Example 1:

[0025] like Figure 1 As shown in Figure 2, a high-speed punching machine for stainless steel thin plates includes a machine base 1. A platform 17 and a frame 2 are respectively provided on the top two sides of the machine base 1. A main shaft 6 is rotatably connected to the top of the frame 2, and a lower die 10 is fixed to the bottom of the frame 2. A stamping assembly and an upper die 9 are provided between the main shaft 6 and the lower die 10. The stamping assembly drives the upper die 9 to rise and fall. A drive assembly and a transmission assembly are respectively provided on both sides of the frame 2. The drive assembly drives the main shaft 6 to rotate, and the transmission assembly is connected to the end of the main shaft 6. The transmission assembly includes a feeding unit and a misalignment unit. The feeding unit is used to drive the platform 17 to move back and forth, and the misalignment unit is used to drive the upper die 9 to move left and right.

[0026] The high-speed punching equipment for stainless steel sheets in this embodiment uses a drive assembly. The main shaft 6 drives the stamping assembly to complete the stamping action on the sheet metal, and drives the transmission assembly to complete the feeding of the sheet metal and the left and right movement of the upper die 9. This achieves single motor 3 drive, which greatly saves the time between each action and improves the punching efficiency.

[0027] The drive assembly includes a motor 3, a belt 4 and two pulleys 5. The motor 3 is fixed below the machine base 1, and the two pulleys 5 are respectively sleeved on the output shaft of the motor 3 and the end of the main shaft 6. The belt 4 connects the two pulleys 5.

[0028] The stamping assembly includes an eccentric sleeve 7 and a pressure plate 8. The eccentric sleeve 7 is sleeved on the main shaft 6, and the pressure plate 8 is located below the eccentric sleeve 7 and in contact with the eccentric sleeve 7. Both sides of the pressure plate 8 move up and down along the guide rail 11, which is fixed to both sides of the frame 2. The upper die 9 is fixed to the pressure plate 8. When the eccentric sleeve 7 rotates, it will generate eccentric movement, periodically squeezing the pressure plate 8. With the help of the return spring 24, the pressure plate 8 can always be in contact with the eccentric sleeve 7.

[0029] The feeding unit includes an eccentric wheel 12, a first swing arm 13, a connecting rod 14, and a drive rod 15. The eccentric wheel 12 is sleeved on the end of the main shaft 6. The middle part of the first swing arm 13 is hinged to the side wall of the frame 2. A roller is provided at the top of the first swing arm 13, and the roller abuts against the outer wall of the eccentric wheel 12. The bottom end of the first swing arm 13 is hinged to one end of the connecting rod 14, and the other end of the connecting rod 14 is hinged to one end of the drive rod 15. The other end of the drive rod 15 is hinged to the machine base 1 and the drive rod 15 is hinged to the platform 17. Guide rods 16 are provided on both sides of the machine base 1. A slider is slidably fitted on the guide rod 16, and the slider is fixed to the bottom of the platform 17. When the eccentric wheel 12 rotates, the first swing arm 13 swings periodically. Through the transmission of the connecting rod 14 and the drive rod 15, the platform 17 is driven to move back and forth periodically along the guide rod 16.

[0030] The misalignment unit includes a drive gear 20, an eccentric gear 21, a second swing arm 22, and a push block 23. The drive gear 20 is sleeved on the end of the main shaft 6. The eccentric gear 21 is rotatably connected to the side wall of the frame 2. The eccentric gear 21 has an annular protrusion on the side away from the side wall of the frame 2, and the height of one end of the protrusion gradually decreases towards the other end. The middle part of the second swing arm 22 is hinged to the frame 2. The top end of the second swing arm 22 abuts against the protrusion through a roller, and the bottom end of the second swing arm 22 abuts against the push block 23 through a roller. The push block 23 is fixed to the pressure plate 8. Guide posts are provided at both ends of the pressure plate 8. The guide posts are fixed to the machine base 1. A return spring 24 is sleeved on the guide post and is located between the machine base 1 and the push block 23. The guide post has a certain elasticity. Due to the unevenness of the protrusion, the second swing arm 22 swings once when the eccentric gear 21 rotates one revolution, which works in conjunction with the return function of the guide post. This causes the pusher block 23 to move left and right once, thereby achieving a certain distance displacement between the upper row of holes and the lower row of holes.

[0031] The top of the platform 17 is provided with a positioning strip 18; one end of the positioning strip 18 is sleeved on the slide rod, and the slide rod is fixed to one end of the platform 17; therefore, the positioning strip 18 can move along the slide rod, thereby adjusting according to the width of the thin plate, which has good adaptability.

[0032] The top of the platform 17 is provided with a pressure rod 19. The two ends of the pressure rod 19 are rotatably connected to the platform 17 through torsion springs. Pressure plates are evenly distributed on the pressure rod 19. The pressure plates press the thin plate onto the platform 17. The torsion springs can provide pressure to the pressure rod 19 and the pressure plates, so that the pressure plates always press the thin plate. The torsion springs can be adjusted to adjust the pressure of the pressure plates to adapt to different thicknesses of thin plates.

[0033] Each of the four corners of the machine base 1 is provided with a shock-absorbing support leg 25, and the shock-absorbing support leg 25 is fitted with a shock-absorbing spring, which is used to buffer the vibration of the machine base 1.

[0034] Working principle: Motor 3 drives the main shaft 6 to rotate via belt 4 and pulley 5, which in turn drives the eccentric wheel 12 to rotate. The rotation of the eccentric wheel 12 causes the first swing arm 13 to swing. Through the transmission of connecting rod 14 and drive rod 15, the platform 17 moves forward along the guide rod 16 to realize the feeding of the thin plate. At this time, the thin plate enters the lower die 10, which then drives the eccentric sleeve 7 to move eccentrically, causing the pressure plate 8 and the upper die 9 to press down. Together with the lower die 10, the thin plate is punched. Then the eccentric wheel 12 and the eccentric sleeve 7 continue to rotate, but the upper die 9 and the lower die 10 still press down on the thin plate to ensure the punching quality. The platform 17 moves backward, and the above operation is repeated to realize the feeding and punching of the thin plate. At the same time, the main shaft 6 can also drive the drive gear 20 to rotate, causing the second swing arm 22 to swing and drive the push block 23 to move, so that the pressure plate 8 can move left and right a certain distance, thereby realizing the staggered setting of two rows of holes.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
