[0026] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0027] like Figure 1-Figure 8 As shown, the aluminum plate trimming and shearing device includes a work surface 1, two groups of conveying roller groups 2 arranged on the work surface 1, and shearing components 3 symmetrically arranged at both ends of the conveying roller group 2, wherein the conveying roller group 2 includes a portal frame 4, an upper conveying roller 5 and a lower conveying roller 6 rotatably supported on the inner side of the portal frame 4.

[0028] The shearing assembly 3 includes a mounting seat 7, two rotating shafts 8 rotatably connected to the upper and lower sides of the mounting seat 7, two disc cutters 9 respectively fixedly connected to the two rotating shafts 8, and a cutting mechanism 10 arranged downstream of the disc cutters 9 along the conveying direction of the aluminum plate, wherein both ends of the conveying roller group 2 are provided with a vertically arranged fixed plate 11 extending along the conveying direction of the aluminum plate, a horizontally arranged support plate 12 is fixedly connected to the fixed plate 11, and the mounting seat 7 is slidably connected to the support plate 12.

[0029] The upper and lower disc knives 9 form a group, and several groups of disc knives 9 are arranged along the conveying direction of the aluminum plate. The two rotating shafts 8 are in the same vertical plane and are symmetrically arranged up and down. The two disc knives 9 are also symmetrically arranged up and down, and the blade tips 13 of the two disc knives 9 are arranged at intervals and correspond to each other in the vertical direction. Along the conveying direction of the aluminum plate, the interval between the upper and lower disc knives 9 of each group gradually decreases. The interval between the two disc knives 9 is less than the thickness of the aluminum plate. The cutting mechanism 10 includes a cutting knife 14, and the blade of the cutting knife 14 corresponds to the indentation of the aluminum plate. By arranging multiple groups of disc knives 9, and gradually reducing the interval between the upper and lower disc knives 9 of each group along the conveying direction of the aluminum plate, the thicker aluminum plate can be gradually indented by multiple groups of disc knives 9 when cutting the edges.

[0030] There is an angle of 30°-60° between the two disc cutters 9, and the disc cutter 9 has a blade portion 15, and the cross-sectional shape of the blade portion 15 is an isosceles triangle. The blade portion 15 has a first blade surface 16 and a second blade surface 17. The first blade surface 16 is located on a side of the disc cutter 9 away from the rotating shaft 8, and the bottom end of the first blade surface 16 of the disc cutter 9 located on the upper side and the top end of the first blade surface 16 of the disc cutter 9 located on the lower side pass through the same vertical line.

[0031] A driving member 18 for driving the two rotating shafts 8 is provided on the mounting seat 7. The driving member 18 includes a driving shaft 19 whose two ends are respectively rotatably connected to the mounting seat 7 and the fixed plate 11, an active bevel gear 20 fixedly connected to the driving shaft 19 and located in the mounting seat 7, a passive bevel gear 21 fixedly connected to the rotating shaft 8 and meshing with the active bevel gear 20, a worm gear 22 connected to the driving shaft 19, a worm 23 rotatably supported on the fixed plate 11 through an axle seat and meshing with the worm gear 22, and a driving motor 24 connected to the worm 23.

[0032] When the driving motor 24 drives the worm 23 to rotate, it also drives the worm wheel 22 on the same fixed plate 11 to rotate synchronously, so that the driving shaft 19 drives the active bevel gear 20 to rotate, and also drives the two passive bevel gears 21 to rotate synchronously, thereby driving the two disc cutters 9 to rotate synchronously to roll the aluminum plate.

[0033] The cutting mechanism 10 is arranged on the portal frame 4 of the conveying roller group 2 downstream along the conveying direction of the aluminum plate. The cutting mechanism 10 includes a mounting plate 25 fixedly connected to the portal frame 4, and a mounting groove 26 opened on the mounting plate 25 near one side of the aluminum plate. The cutting knife 14 is fixedly installed in the mounting groove 26, and the mounting groove 26 is V-shaped. The cutting knife 14 is set to be V-shaped to match the mounting groove 26, and the cross-section of the blade of the cutting knife 14 is a right-angled triangle with its right-angled side facing one side of the aluminum plate. By setting the mounting plate 25 and opening the mounting groove 26 on the mounting plate 25, the cutting knife 14 is installed in the mounting groove 26. Since the cutting knife 14 is V-shaped, when the indentation of the aluminum plate passes through the V angle of the cutting knife 14, it can generate an up and down squeezing force on the indentation, thereby ensuring the stability of the force between the aluminum plate and the cutting knife 14 and reducing the bending of the aluminum plate.

[0034] To facilitate replacement of the cutting knife 14, the cutting knife 14 includes a plurality of blade units 27. The blade units 27 are each provided with a mounting hole. A countersunk bolt 28 threadedly connected to the inner wall of the mounting groove 26 is provided in the mounting hole. By configuring the cutting knife 14 to be composed of a plurality of blade units 27, the blade units 27 can be easily replaced after the cutting knife 14 has been used for a long time.

[0035] In order to facilitate the adjustment of the position and spacing of each set of disc cutters 9, the worm wheel 22 has a center hole 29, the drive shaft 19 is slidably inserted into the center hole 29, and a spline 30 is provided between the drive shaft 19 and the inner wall of the center hole 29. The end surface of the worm wheel 22 close to the fixed plate 11 is fixedly connected to a first support ring 31, and the fixed plate 11 is fixedly connected to a second support ring 32 which is rotatably connected to the first support ring 31. The drive shaft 19 passes through the fixed plate 11 and extends to the other side. The drive shaft 19 extends to the other side of the fixed plate 11. An adjusting ring groove 33 is provided at one end, and an adjusting plate 34 is provided on the side of the fixed plate 11 away from the supporting plate 12. The adjusting plate 34 is parallel to the fixed plate 11 and is slidably connected to the fixed plate 11 through a plurality of guide rods 35. An adjusting hole 36 is provided on the adjusting plate 34 corresponding to the driving shaft 19. The adjusting ring grooves 33 are rotatably connected in the adjusting holes 36 one by one. An adjusting electric cylinder 37 is fixedly installed on the side of the adjusting plate 34 away from the fixed plate 11, and the piston rod of the adjusting electric cylinder 37 passes through the adjusting plate 34 and is fixedly connected to the fixed plate 11.

[0036] The rotating shaft 8 is a telescopic structure, and the rotating shaft 8 includes a rotating sleeve 38 rotatably connected to the mounting seat 7, an extension rod 39 slidably connected to the rotating sleeve 38, a spline 30 provided between the rotating sleeve 38 and the extension rod 39, an adjusting nut 40 rotatably connected to the end face of the rotating sleeve 38, and an axial connecting member 41 provided between the adjusting nut 40 and the rotating sleeve 38, wherein the axial connecting member 41 includes a limiting ring groove 42 provided on the end face of the rotating sleeve 38, and a connecting ring 43 fixedly connected to the end face of the adjusting nut 40 and rotatably connected to the limiting ring groove 42, and the cross sections of the limiting ring groove 42 and the connecting ring 43 are both T-shaped. When the rotating shaft 8 needs to be telescopic, the extending rod 39 is moved axially along the rotating sleeve 38 under the limit of the spline 30 by rotating the adjusting nut 40, so as to perform telescopic adjustment.

[0037] When the spacing of the cutting edges needs to be adjusted, the adjusting electric cylinder 37 is started to drive the adjusting plate 34 to move. With the cooperation of the adjusting ring groove 33 and the adjusting hole 36, the disc cutter 9 on the same side of the aluminum plate can be driven to move synchronously, thereby adjusting the spacing between the disc cutters 9 on both sides to adapt to aluminum plates of different sizes. By setting the rotating shaft 8 as a telescopic structure and the rotating shaft 8 being inclined, when the rotating shaft 8 is extended or retracted, the disc cutter 9 can be driven to move axially along the rotating shaft 8. This displacement can be decomposed into vertical displacement and horizontal displacement. The disc cutter 9 can compensate for its horizontal displacement by adjusting the extension and retraction of the adjusting electric cylinder 37, while retaining the vertical displacement of the disc cutter 9, that is, the spacing between the upper and lower disc cutters 9 can be adjusted to adapt to aluminum plates of different thicknesses.

[0038] The mounting plate 25 is located between the cutting knife 14 and the conveying roller group 2 and is provided with a grinding wheel 44. The grinding wheel 44 is located on the side of the mounting plate 25 close to the aluminum plate, and the end surface of the grinding wheel 44 close to the aluminum plate and the surface of the cutting knife 14 close to the aluminum plate are located in the same horizontal plane. A grinding motor 45 connected to the grinding wheel 44 is fixedly installed on the other side of the mounting plate 25. When the aluminum plate has high process requirements, the cut edges of the aluminum plate are directly polished and smoothed by the grinding wheel 44 after cutting.

[0039] The implementation principle of the present invention is: When the aluminum plate is pulled and transported by the conveying roller group 2, its two sides pass between the upper and lower disc knives 9. Since there is a gap between the blade tips 13 of the disc knives 9, an indentation is squeezed out of the aluminum plate passing between the upper and lower disc knives 9. Since the upper and lower sides of the aluminum plate are subjected to force at the same time, the aluminum plate will not bend while being squeezed out of the indentation. When the indentation on the aluminum plate passes through the cutting knife 14, the cutting knife 14 cuts off the waste edge along the indentation, thereby completing the trimming process. The shear surface is flat and will not bend. No leveling is required. Products with lower process standards do not need to be polished after cutting, which reduces process steps and reduces production costs.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
