[0026] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0027] As Figures 1 to 6 shown, a high-speed gantry punching machine provided by an embodiment of the present utility model includes a frame 1 and a crankshaft connecting rod mechanism. The crankshaft connecting rod mechanism is provided on the frame 1. The punching unit is further included. The punching unit includes a slide rail 2 and a stamping head 3. The output end of the crankshaft connecting rod mechanism is connected to the slide rail 2. The stamping head 3 is provided on the slide rail 2. Two positioning plates 4 are symmetrically arranged on both sides of the slide rail 2. A plurality of perforations 5 are evenly opened on the two positioning plates 4. A T-shaped round rod 6 is slidably installed in each of the perforations 5. A spring 7 is sleeved on each of the T-shaped round rods 6. The bottom ends of the T-shaped round rods 6 are commonly connected to a tightening plate 8. A rubber plate 9 is provided at the bottom end of the tightening plate 8.

[0028] Specifically, the frame body 1 is an installation frame for carrying the crankshaft connecting rod mechanism. The crankshaft connecting rod mechanism includes a driving member 10. The driving member 10 is installed at the top end of the frame body 1. The output end of the driving member 10 is connected with a first synchronous pulley 11. A driving circular rod 12 is rotatably installed on the frame body 1. One end of the driving circular rod 12 penetrates through the frame body 1 and is connected with a second synchronous pulley 13. The second synchronous pulley 13 and the first synchronous pulley 11 are connected and driven by a first synchronous belt 14; Two crankshaft bodies 15 are symmetrically installed on the driving circular rod 12. A connecting rod body 16 is rotatably connected to each of the two crankshaft bodies 15. A pressing rod 17 is rotatably connected to each of the two connecting rod bodies 16. An inverted U-shaped frame 18 is installed at the bottom end of the frame body 1. Two through grooves 19 are symmetrically formed at the top end of the U-shaped frame 18. The two pressing rods 17 are respectively slidably installed in the corresponding through grooves 19. A slide rail 2 is commonly installed at the bottom ends of the two pressing rods 17. A sliding rod 20 is slidably installed in the slide rail 2. A plurality of punching heads 3 are evenly arranged at the bottom end of the sliding rod 20;Both ends of the sliding rod 20 are provided with a plurality of first threaded holes 21. Both ends of the slide rail 2 are provided with a plurality of second threaded holes 22. Each first threaded hole 21 is threadedly connected to a second threaded hole 22 through a threaded rod 23. The bottom end of the U-shaped frame 18 is provided with a bottom plate 24. A lower die 25 is arranged on the U-shaped frame 18. A plurality of through holes 26 adapted to the punching heads 3 are evenly arranged on the lower die 25. An intermittent feeding mechanism is arranged on the frame body 1. The intermittent feeding mechanism feeds the punching material by the synchronous rotation of two feeding rollers. The way of intermittent feeding of the intermittent feeding mechanism is common knowledge in the art and will not be elaborated. When the intermittent feeding mechanism conveys the punching material to a suitable punching position on the lower die 25, the driving member 10 (the driving member 10 is a device whose conveying end can perform forward and reverse movements, preferably a motor) is started to drive the first synchronous wheel 11 to rotate. The first synchronous wheel 11 and the second synchronous wheel 13 are driven by a first synchronous belt 14 to rotate each other, so that the first synchronous wheel 11 drives the second synchronous wheel 13 to rotate. The second synchronous wheel 13 drives the driving round rod 12 to rotate. The driving round rod 12 drives the two crankshaft bodies 15 to rotate. The two crankshaft bodies 15 drive the connecting rod bodies 16 connected thereto to rotate. The two connecting rod bodies 16 drive the pressing rods 17 connected thereto to move towards the bottom end in the through groove 19. The two pressing rods 17 synchronously drive the slide rail 2 to move towards one end of the lower die 25. The slide rail 2 drives the positioning plate 4 to move towards one end of the lower die 25. The positioning plate 4 drives the pressing plate 8 and the rubber plate 9 to first press against the punching material through the T-shaped round rod 6, so that the pressing plate 8 and the rubber plate 9 perform a positioning operation on the punching material. Since the pressing plate 8 and the rubber plate 9 press and position the punching material, the pressing plate 8 and the rubber plate 9 slide tightly on the punching material, so that the spring 7 is in a stretched state. And the elastic force of the spring 7 acts on the pressing plate 8 and the rubber plate 9, making the pressing and positioning of the pressing plate 8 and the rubber plate 9 on the punching material more stable. At the same time, the slide rail 2 drives the sliding rod 20 to move towards one end of the lower die 25. The sliding rod 20 drives the punching head 3 to move towards one end of the lower die 25, so that the punching head 3 performs a punching operation on the punching material. By the punching head 3 being adapted to the through holes 26 on the lower die 25, the punching head 3 punches the punching material into the required shape. And because the pressing plates 8 and the rubber plates 9 on both sides of the slide rail 2 press and position the punching material, the punching position of the punching head 3 on the punching material is more accurate, improving the punching quality of the punching material. When the punching of the punching material is completed, the crankshaft connecting rod mechanism drives the punching head 3 to slide out of the through hole 26, and then the intermittent feeding mechanism continues to feed the punching material until the punching material moves to the next punching position. Repeating the above operations can continuously punch the punching material, improving the punching efficiency of the punching material.;

[0029] When it is necessary to adjust the positions of the adjusting sliding rod 20 and the stamping head 3, since the spacing between the first threaded holes 21 on the sliding rod 20 is the same as the spacing between the second threaded holes 22 on the slide rail 2, and the number of the first threaded holes 21 on the sliding rod 20 is less than the number of the second threaded holes 22 on the slide rail 2, the staff uses a tool to screw out the threaded rod 23 from the second threaded hole 22, and then pushes the sliding rod 20 to slide within the slide rail 2, so that the sliding rod 20 drives the stamping head 3 to move to a suitable stamping position. Then, the threaded rod 23 is screwed into the second threaded hole 22, so that the threaded rod 23 positions the sliding rod 20 and the stamping head 3, enabling the stamping head 3 to perform accurate stamping operations on the stamping material. When it is necessary to replace the stamping head 3, the staff uses a tool to screw out the threaded rod 23 from the second threaded hole 22, then pushes the sliding rod 20 out of the slide rail 2, slides the new sliding rod 20 and the stamping head 3 into the slide rail 2, and then screws the threaded rod 23 into the second threaded hole 22, so that the threaded rod 23 positions the sliding rod 20 and the stamping head 3, and the replacement operation of the stamping head 3 can be realized, with convenient replacement and adjustment.

[0030] In the prior art, when a high-speed gantry punching machine performs stamping operations on materials, since the materials are relatively thin and not limited, the materials may shift during stamping, resulting in deviation of the stamping positions of the materials and affecting the stamping quality of the materials.

[0031] The beneficial effects of this embodiment are as follows: The crankshaft connecting rod mechanism drives the slide rail 2 and the stamping head 3 to move downward. The slide rail 2 drives the positioning plate 4 to move downward. The positioning plate 4 drives the pressing plate 8 and the rubber plate 9 to first press against the stamping material through the T-shaped round rod 6, so that the pressing plate 8 and the rubber plate 9 position the stamping material. Then, the slide rail 2 drives the stamping head 3 to perform stamping operations on the stamping material. Since the pressing plate 8 and the rubber plate 9 press and position the stamping material, the pressing plate 8 and the rubber plate 9 are pressed by the stamping material, causing the spring 7 to be in a stretched state. And the elastic force of the spring 7 acts on the pressing plate 8 and the rubber plate 9, making the pressing and positioning of the stamping material by the pressing plate 8 and the rubber plate 9 more stable. Since the pressing plates 8 and the rubber plates 9 on both sides of the slide rail 2 press and position the stamping material, the stamping position of the stamping head 3 on the stamping material is more accurate, improving the stamping quality of the stamping material.

[0032] In another embodiment provided by the present utility model, a collection unit is provided on the U-shaped frame 18. The collection unit is used for collecting stamping waste. The collection unit includes a collection frame 27. The collection frame 27 is arranged between the inner walls of the U-shaped frame 18. A driven shaft 28 is rotatably installed on the collection frame 27. A driven plate 29 is installed on the driven shaft 28. A collection box 30 is installed on the driven plate 29. One end of the driven shaft 28 penetrates through the U-shaped frame 18 and is connected with a driven gear 31. A rack 32 is installed on the side wall of the slide rail 2. The rack 32 and the driven gear 31 are meshed with each other. An arc-shaped panel 38 is arranged on the side wall of the U-shaped frame 18. The center of the arc-shaped panel 38 coincides with the center of the driven shaft 28.

[0033] Specifically, when the stamping head 3 finishes stamping the stamping material, the waste material stamped by the stamping head 3 on the stamping material falls into the collection box 30. Then, the crankshaft connecting rod mechanism drives the stamping head 3 to slide out of the through hole 26. The slide rail 2 drives the rack 32 to slide upward. Since the rack 32 and the driven gear 31 are meshed with each other, the rack 32 drives the driven gear 31 to rotate 180 degrees. The driven gear 31 drives the driven shaft 28 to rotate 180 degrees. The driven shaft 28 drives the collection box 30 to rotate 180 degrees through the driven plate 29, so that the opening of the collection box 30 faces downward, and the waste material in the collection box 30 slides out of the collection box 30. When the crankshaft connecting rod mechanism drives the stamping head 3 to move downward next time, the slide rail 2 drives the rack 32 to move downward. The rack 32 drives the driven gear 31 to rotate 180 degrees. The driven gear 31 drives the driven shaft 28 to rotate 180 degrees. The driven shaft 28 drives the collection box 30 to rotate 180 degrees through the driven plate 29, so that the collection box 30 is aligned with the through hole 26 on the lower die 25. The collection box 30 collects the waste material stamped by the stamping head 3 on the stamping material. By repeating the above operations, each time the stamping head 3 performs stamping, the collection box 30 can collect the stamping waste. There is no need for staff to perform secondary collection and treatment on the waste material. And since the center of the arc-shaped panel 38 coincides with the center of the driven shaft 28, when the collection box 30 rotates back and forth by 180 degrees, the arc-shaped panel 38 can perform a closing operation on the opening of the collection box 30. Only when the opening of the collection box 30 faces upward (that is, the opening of the collection box 30 is aligned with the through hole 26 on the lower die 25) and the opening faces downward, the opening of the collection box 30 is not closed. Through the setting of the arc-shaped panel 38, the opening of the collection box 30 can be closed, preventing the waste material in the collection box 30 from being thrown out of the collection box 30 during rotation and causing the waste material to be randomly placed on the bottom plate, and enabling stable collection of the waste material.

[0034] In another embodiment provided by the present utility model, conveying rollers 33 are symmetrically installed on the U-shaped frame 18, and the two conveying rollers 33 are connected by a conveying belt 34. One end of one of the conveying rollers 33 penetrates through the U-shaped frame 18 and is connected with a third synchronous pulley 35. A fourth synchronous pulley 36 is coaxially connected to the second synchronous pulley 13, and the fourth synchronous pulley 36 and the third synchronous pulley 35 are connected by a second synchronous belt 37.

[0035] Specifically, when the opening of the collection box 30 faces downward, the waste materials in the collection box 30 fall onto the conveying belt 34. When the second synchronous pulley 13 rotates, the second synchronous pulley 13 drives the fourth synchronous pulley 36 to rotate through the second synchronous belt 37. The fourth synchronous pulley 36 drives the conveying roller 33 connected thereto to rotate, and the conveying roller 33 drives the conveying belt 34 to rotate, so that the conveying belt 34 conveys the waste materials, facilitating the staff to collect the waste materials. Moreover, by driving the fourth synchronous pulley 36 to rotate through the second synchronous pulley 13, the fourth synchronous pulley 36 drives the conveying belt 34 to convey the waste materials through the conveying roller 33, without setting a power unit on the conveying roller 33 to drive the conveying roller 33 to rotate, reducing the cost of waste material collection.

[0036] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
