DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] Please see attached Figure 1-2 The utility model provides an aluminum plate shearing mechanism, including a side slider 10, a side support 20, a crossbeam 30, a shearing knife 40, a shearing roller 50 and a linkage; the crossbeam 30 extends in the left and right directions, and a side slider 10 is fixed at each end of the crossbeam 30, so that a feeding space is formed between the two side sliders 10; the side slider 10 is a front-to-back mirror-symmetrical structure, and each side slider 10 is slidably connected to a side support 20 front and back, so that the side slider 10 is suspended; the shearing knife 40 is fixedly connected to the crossbeam 30, and its lower side protrudes from the lower surface of the crossbeam 30; the shearing roller 50 is located in the feeding space and corresponds to the shearing knife 40; the linkage is connected to the side slider 10 and the shearing roller 50, so that the shearing roller 50 rises and falls in the feeding space, and the side slider 10 moves forward and backward along the side support at the same time; when the shearing roller 50 rises to the highest point, the shearing roller 50 and the shearing knife 40 cut the aluminum plate.

[0030] The side support 20 provides stable support for the side slider 10, so that the slider 10 is completely suspended in the air, and no other guides or fixings are required, which simplifies the structure of the entire shearing mechanism and facilitates maintenance; the shearing knife 40 is fixed to the front side of the beam 30 by screws, which makes it easy to observe the rust and damage on the surface of the shearing knife 40.

[0031] In a specific embodiment, the aluminum plate passes through the feeding space along the front-to-back direction and moves between the shearing knife 40 and the shearing roller 50, and the cutting and pushing process is specifically as follows: in the initial state, the side slider 10 is in the middle position in the front-to-back direction, the shearing roller 50 is at the lowest point, the shearing roller 50 is separated from the shearing knife 40, and the aluminum plate is transported forward; during shearing, the side slider 10 moves backward along the side support 20, the shearing roller 50 rises to the highest point and cooperates with the shearing knife 40 to cut the aluminum plate, and then the side slider 10 moves forward along the side support 10, and the shearing roller 50 moves forward with the side slider 10 to contact the end face of the cut aluminum plate, and then pushes the aluminum plate forward; repeat the above process to achieve continuous cutting of the aluminum plate. The improved aluminum plate shearing mechanism realizes the pushing function after the aluminum plate is sheared, which effectively avoids the problem of aluminum plate retention.

[0032] In the present application, the specific structure of the side slider 10 is as follows: the side slider 10 includes a side slider body 110, and side slider bosses 120 are respectively provided at the front and rear ends of the side slider body 110; in each of the side slider bosses 120, side rollers 130 are respectively rotatably provided on the top and bottom surfaces of the side slider bosses 120, and the axes of the side rollers 130 extend in the left and right directions; the side surfaces of the side slider bosses 120 are recessed inwardly, which can reduce part of the weight and reduce the supporting pressure of the side support 20.

[0033] In the present application, the specific structure of the side support 20 and the assembly relationship between it and the side slider 10 are as follows: the side support 20 includes a side support body 210, and the side support body 210 has side support bosses 220 arranged in mirror symmetry on the upper and lower sides, the side slider boss 120 is arranged between the two side support bosses 220, and the side roller 130 is rollingly connected to the side support boss 220; by respectively arranging the side support bosses 220 on the upper and lower sides of the side slider boss 120, the side slider boss 120 is clamped The support not only provides a moving carrier for the side slider 10 in the front-to-back direction, but also prevents the side slider 10 from tipping over in the longitudinal direction due to the clamping of the side slider boss 120; similarly, since the specific shape of the side support seat body 210 is a plate, the outer side of the measuring slider body 110 is restricted by the measuring support seat body 210, preventing the side slider 10 from deviating to the left and right during the front-to-back movement. Therefore, the side support seat 20 has a comprehensive limiting function, ensuring that the side slider 10 can slide along a predetermined direction even in a suspended state, without the need to set other additional limiting parts, and is easy to maintain.

[0034] In the present application, in order to increase the connection strength between the side support body 210 and the side support boss 220 , a side support support 230 is provided between the side support body 210 and the side support boss 220 , and the side support support 230 is provided on a side away from the side slider boss 120 .

[0035] As a specific embodiment of the present application, the linkage part includes a linkage cam 60, and an accommodating cavity 111 is arranged on the side slider body 110 along the left-right direction, and the linkage cam 60 is hidden in the accommodating cavity 111; the left and right sides of the linkage cam 60 are respectively eccentrically provided with a first linkage shaft 610 and a second linkage shaft 620, the first linkage shaft 610 is used to connect the rotating drive member, and the second linkage shaft 620 is used to connect the shearing roller 50; wherein, when the linkage cam 60 rotates eccentrically, it contacts the cavity wall of the accommodating cavity 111 and drives the side slider body 110 to move forward and backward, and at the same time drives the shearing roller 50 to rise and fall.

[0036] In this embodiment, the eccentric rotation characteristic of the cam 60 is utilized to decompose the eccentric rotation of the cam into the forward and backward movement of the side slider 10 and the lifting and lowering movement of the shearing roller 50, thereby realizing the processing effect of the dual functions of shearing and pushing, effectively avoiding the problem of aluminum plate retention. At the same time, when the cam is fed, the movement trajectory of the shearing roller 50 is arc-shaped to avoid scratching the aluminum plate.

[0037] Specifically, the rotary drive member is a motor.

[0038] Furthermore, it is only necessary to arrange a linkage member on one of the side sliders 10, while the other side slider 10 is directly connected to the shear roller 50 by a bearing (not shown), thereby further saving costs.

[0039] In order to reduce the weight of the cross beam 30 and alleviate the load, a plurality of hollow portions 310 are provided at intervals along the left-right direction on the cross beam 30 , and the hollow portions 310 penetrate the cross beam 30 along the front-back direction.

[0040] In order to prevent the aluminum plate from bouncing up when shearing, a stopper 320 is provided on the side of the beam 30, and the stopper 320 is not lower than the bottom surface of the shearing knife 40; when the aluminum plate bounces up after shearing, it is blocked by the stopper 320, which effectively prevents the aluminum plate from bouncing up and injuring people or flying out of the working environment.

[0041] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
