Description

Technical Field

[0001] This utility model relates to the technical field of metal sheet shearing line equipment, and more specifically, to a rear baffle swing mechanism applied to a shearing line palletizer. Background Technology

[0002] A sway shearing line is a production line equipment that automates the cutting of metal sheets (such as steel, aluminum, and stainless steel) to preset sizes and shapes. Its core component is a swaying shearing mechanism, which achieves rapid and precise cutting of the sheet metal through the swaying motion of the blade holder. Sway shearing lines typically integrate uncoiling, leveling, shearing, and stacking modules, making them suitable for large-scale, continuous metal sheet processing. They are widely used in metal processing, home appliance manufacturing, and automotive parts production.

[0003] Currently, the back gauge in sway shearing lines typically employs a multi-stage transmission mechanism, which suffers from drawbacks such as high cost, complex structure, and large size. Due to its large size, the back gauge cannot accommodate narrower sheet metal production, limiting its usability. For a long time, the industry has accepted this existing structure without effective improvement. This invention aims to solve the above problems by providing a back gauge swing mechanism that is simple in structure, has high transmission efficiency, and can adapt to the production needs of sheet metal of different widths. Utility Model Content

The left and right ends of the lead screw nut are fixed by two sets of bearing seats. A push plate is fixed on the left end of the lead screw. A force plate is provided on the right end of the rear baffle corresponding to the push plate. The force plate and the push plate are rotatably connected by a connecting rod. Both the force plate and the push plate are hinged to the connecting rod by pins.

[0007] Furthermore, a through slot is provided on the partition plate at the position corresponding to the chain, and the chain passes through the slot to connect the driving sprocket and the driven sprocket.

[0008] Furthermore, a back plate is fixed at the right end face of the transmission box behind the partition, and a movable hole adapted to the lead screw is opened on the back plate, into which the right end of the lead screw extends.

[0009] Furthermore, a circular movable slot is provided on the left end face of the transmission box at a position corresponding to the lead screw, and the diameter of the movable slot is greater than the length of the push plate.

[0010] Furthermore, two sets of connecting slides for connecting external equipment are fixed on the upper side of the transmission box.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] Example: Figures 1 to 6As shown, a rear baffle swing mechanism applied to a swaying shear line palletizer includes a transmission box 1 and a rear baffle 4. The transmission box 1 has a rear baffle spaced apart on its left side. Two sets of movable connecting lugs 5 are fixedly mounted on the right end face of the rear baffle 4. Two sets of fixed connecting lugs 6, adapted to the movable connecting lugs 5, are fixedly mounted on the left end face of the transmission box 1. The movable connecting lugs 5 and the fixed connecting lugs 6 are rotatably connected by pins 7, providing basic rotational support for the swing of the rear baffle 4. A position proximity switch 8 is installed near the lower corner of the left end face of the transmission box 1. The transmission box 1 is used to detect the position of the rear baffle 4 and achieve precise control of the swing position of the rear baffle 4. A partition 9 is vertically fixed inside the transmission box 1. A drive motor 2 is installed on the front side of the partition 9. A drive sprocket 16 is installed on the output end of the drive motor 2. A horizontal lead screw 18 is provided in the transmission box 1 behind the partition 9. A matching lead screw nut 21 is sleeved on the ring surface of the lead screw 18. A driven sprocket 22 is fixedly sleeved on the ring surface of the lead screw 21. The driven sprocket 22 is connected to the drive sprocket 16 through a chain 15, so that the power can be transmitted from the drive motor to the drive sprocket 16. The transmission from machine 2 to lead screw 18 drives lead screw nut 21 to rotate, which in turn drives lead screw 18 to move horizontally. The left and right ends of lead screw nut 21 are fixed by two sets of bearing seats 19, which restrict the horizontal movement of lead screw nut 21 and ensure the stability of lead screw 18's rotation. A push plate 11 is fixed to the left end of lead screw 18, and a force-bearing plate 13 is provided on the right end face of the rear baffle corresponding to the push plate 11. The force-bearing plate 13 and the push plate 11 are connected by a communication channel. The connecting rod 12 is rotatably connected, and the force plate 13 and the push plate 11 are both hinged to the connecting rod 12 via the pin 121. The push plate 11 moves by moving left and right through the lead screw 18, and then the back baffle 4 swings through the connecting rod 12. This design solves the problem that the back baffle 4 in the existing swing shearing equipment usually adopts a multi-stage transmission mechanism. This structure has the defects of high cost, complex structure and large size. Moreover, due to the large structural size, the back baffle 4 cannot adapt when the swing shearing line produces relatively narrow plates, resulting in limited use.

[0026] In this embodiment, a through slot 14 is provided on the partition 9 at a position corresponding to the chain 15, through which the chain 15 passes to connect the driving sprocket 16 and the driven sprocket 22. The slot 14 facilitates the passage of the chain 15 through the driving sprocket 16 and the driven sprocket 22, providing a channel for the connection of the chain 15.

[0027] In this embodiment, a back plate 10 is fixedly provided on the right end face of the transmission box 1 behind the partition 9. The back plate 10 has a movable hole 17 that is adapted to the lead screw 18. The right end of the lead screw 18 extends into the movable hole 17, which supports and guides the right end of the lead screw 18. At the same time, the right end of the lead screw 18 can extend and retract in the movable hole 17 without affecting the horizontal movement of the lead screw 18.

[0028] In this embodiment, a circular movable slot 20 is provided on the left end face of the transmission box 1 at a position corresponding to the lead screw 18. The diameter of the movable slot 20 is larger than the length of the push plate 11. The movable slot 20 provides space for the movement of the push plate 11 and the connecting rod 12, which can meet the changes in the angular position between the two without interfering with the changes in their displacement.

[0029] In this embodiment, two sets of connecting slides 3 for connecting external equipment are fixedly provided on the upper side of the transmission box 1. A threaded through hole 32 is provided at the center of the connecting slide 3, and sliding grooves 31 are symmetrically provided on the front and rear sides of the threaded through hole 32. This facilitates the stable connection and installation of the mechanism with external equipment. The threaded through hole 32 is used to connect the lead screw 18 on the swing shearing device, and the sliding groove 31 is used to connect the slide rod on the swing shearing device.

[0030] In this embodiment, the rear baffle 4 consists of a protective layer, a buffer pad 42, and a base plate 43. The buffer pad 42 is located on the left side of the base plate 43, and the protective layer is located on the left side of the buffer pad 42. The protective layer, the buffer pad 42, and the base plate 43 are fixedly connected by multiple sets of bolts. The multi-layer structure ensures the strength of the rear baffle 4 and also provides a certain buffering effect, protecting the sheet material and the rear baffle 4 itself.

[0031] The working principle of the rear baffle swing mechanism applied to a swing shearing line palletizer:

[0032] In actual use, the drive motor 2 rotates, which drives the drive sprocket 16 to rotate. The drive sprocket 16 transmits the power to the driven sprocket 22 through the chain 15. The driven sprocket 22 rotates, which in turn drives the screw nut 21 to rotate. Since the screw nut 21 is restricted by the bearing seats 19 at both ends, the screw nut 21 only rotates in its original position and does not produce any lateral displacement. Due to the rotation of the screw nut 21, the drive screw 18 moves horizontally, and then through the action of the connecting rod, the rear baffle 4 swings around the pin 7 as the center of rotation.

[0033] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
