[0002] Metal sheets refer to flat sheets made of metal. Common metal materials include aluminum, steel, copper, zinc, magnesium, etc. They can be divided into thin plates, medium plates and thick plates according to their thickness. Metal sheets usually need to be sheared during the production and processing process, so special shearing equipment is required.

[0003] A feeding device for metal sheet stamping and shearing automation equipment is disclosed in the Chinese utility model patent with announcement number CN219664958U. The device can push the metal sheet onto the conveyor belt through a pushing device, effectively avoiding the situation where the metal sheets need to be placed manually in sequence, thereby greatly improving the work efficiency. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] When the device is actually used, due to the influence of friction, the plate is prone to skew during the pushing process. In addition, the device lacks an integrated structure that can perform position correction, which easily causes the shearing edge of the plate to shift, thereby reducing the processing quality of the plate. For this reason, we provide a plate shearing device. Utility Model Content

[0005] In order to solve the problem in the above background technology that it is difficult to correct the position of the plate, which easily causes the shearing edge of the plate to shift, thereby reducing the processing quality of the plate, the utility model provides a plate shearing device.

[0006] The utility model adopts the following technical solution to achieve: a plate shearing device, comprising:

[0007] A shearing table, wherein the top of the shearing table is fixedly connected to a fixing frame, the top center of the fixing frame is fixedly connected to an electric push rod, the telescopic end of the electric push rod is fixedly connected to a connecting plate, and the bottom of the connecting plate is fixedly connected to a shearing knife;

[0008] An automatic correction component, the automatic correction component comprises four groups of movable plates symmetrically and movably arranged on the top of the shearing table, a push plate is arranged on one side of the movable plate, a cross bar is symmetrically and fixedly connected to one side of the push plate, and the cross bar and the movable plate are slidably connected, a spring is sleeved on the outside of the cross bar, brackets are symmetrically and fixedly connected to both sides of the connecting plate, and a connecting rod is hinged between the bracket and the movable plate through a hinge;

[0009] An automatic downward pressing component comprises a connecting frame symmetrically fixedly connected to the connecting plate, the connecting frame is symmetrically and slidably connected with vertical rods, connecting seats are provided on both sides of the shearing knife and the connecting seats are fixedly connected to two groups of vertical rods on the same side, a pressure roller is rotatably connected to the connecting seat, and a spring 2 is provided on the outer sleeve of the vertical rod.

[0010] As a further improvement of the above solution, a shearing groove is provided on the top of the shearing platform at a position corresponding to the shearing knife.

[0011] As a further improvement of the above solution, one end of the cross bar and the top end of the vertical bar are fixedly connected to a limiting plate.

[0012] As a further improvement of the above solution, two ends of the spring 1 are fixedly connected to the moving plate and the pushing plate respectively.

[0013] As a further improvement of the above solution, two ends of the second spring are fixedly connected to the connecting frame and the connecting seat respectively.

[0014] As a further improvement of the above solution, the bottom of the movable plate is fixedly connected to a limiting slider, and the top of the shearing table is provided with a limiting slot corresponding to the position of the limiting slider and is slidably connected to the limiting slider.

[0015] As a further improvement of the above solution, grooves are symmetrically provided on both sides of the top of the shearing table, and guide rollers are rotatably connected inside the grooves.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. When the electric push rod pushes the shear knife to move vertically downward, the utility model utilizes the hinge effect between the bracket and the push plate and the connecting rod, and the sliding cooperation between the limit slider and the limit slide groove, so that the two sets of movable plates can be pushed to move inward at the same time. When the movable plate moves, it can push the push plate to get close to the plate, so that the position of the plate can be automatically corrected. At the same time, when the push plate first contacts the plate, the shear knife continues to move downward, so that the movable plate can slide on the cross bar and compress the spring 1, so that it can play a certain buffering role to ensure that the shear knife can smoothly cut the plate, and the utility model is highly practical.

[0018] 2. When the electric push rod pushes the shearing knife to move vertically downward, the utility model can also drive the two sets of pressure rollers to move downward together. When the two sets of pressure rollers come into contact with the plate, the shearing knife continues to move downward, so that the connecting frame slides on the outside of the vertical rod and compresses the second spring, which can not only limit the plate to prevent the plate from warping up during shearing, but also play a buffering role to ensure that the plate can be cut smoothly, further improving the practicality of the device.

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] Embodiment 1:

[0027] Please combine Figure 1-4 , a plate shearing device of this embodiment includes:

[0028] A shearing table 1, the top of the shearing table 1 is fixedly connected with a fixing frame 2, the top center of the fixing frame 2 is fixedly connected with an electric push rod 3, the telescopic end of the electric push rod 3 is fixedly connected with a connecting plate, the bottom of the connecting plate is fixedly connected with a shearing knife 4, and a shearing groove is provided at the top of the shearing table 1 corresponding to the position of the shearing knife 4, so as to ensure that the plate can be cut smoothly;

[0029] Automatic correction component, the automatic correction component includes four groups of movable plates 101 symmetrically and movably arranged on the top of the shearing table 1, a push plate 102 is arranged on one side of the movable plate 101, a cross bar 103 is symmetrically and fixedly connected to one side of the push plate 102, and the cross bar 103 is slidably connected to the movable plate 101, a spring 104 is sleeved on the outside of the cross bar 103, and the two ends of the spring 104 are respectively fixedly connected to the movable plate 101 and the push plate 102, and brackets 105 are symmetrically and fixedly connected to both sides of the connecting plate, and a connecting rod 106 is hinged between the bracket 105 and the movable plate 101 through a hinge, and the bottom of the movable plate 101 is fixedly connected to a limiting slider 6, and a limiting slide groove is provided at the position of the limiting slider 6 at the top of the shearing table 1 corresponding to the limit slide groove and is slidably connected to the limit slide groove 6, which can play a certain guiding role in the horizontal movement of the movable plate 101;

[0030] An automatic pressing component includes a connecting frame 201 symmetrically fixedly connected to the connecting plate, and a vertical rod 202 is symmetrically slidably connected to the connecting frame 201. Connecting seats 203 are provided on both sides of the shearing knife 4, and the connecting seats 203 are fixedly connected to the two groups of vertical rods 202 on the same side. A pressure roller 204 is rotatably connected to the connecting seat 203. A spring 205 is provided on the outer sleeve of the vertical rod 202, and the two ends of the spring 205 are respectively fixedly connected to the connecting frame 201 and the connecting seat 203. One end of the cross bar 103 and the top of the vertical rod 202 are fixedly connected to the limiting plate 5, which can prevent the cross bar 103 from being detached from the movable plate 101 and the vertical rod 202 from the connecting frame 201.

[0031] The implementation principle of a plate shearing device in the embodiment of the present application is as follows: first, the plate is placed on the shearing table 1, and then the plate is moved to the bottom of the shearing knife 4 by the rotation cooperation of the guide roller 7, and then the electric push rod 3 is started, and the shearing knife 4 is driven to move vertically downward by the electric push rod 3, so that the plate can be sheared, and in the process of the vertical downward movement of the shearing knife 4, the hinge effect between the bracket 105 and the push plate 102 and the connecting rod 106, and the sliding cooperation between the limit slider 6 and the limit slide groove are used to push the two groups of moving plates 101 to move inward at the same time. When the moving plate 101 moves, it can push the push plate 102 to get close to the plate, so that the position of the plate can be automatically corrected. At the same time, when the push plate 102 first contacts the plate, due to the shearing knife 4 The continued downward movement of the knife 4 allows the movable plate 101 to slide on the cross bar 103 and compress the spring 104, thereby playing a certain buffering role to ensure that the shear knife 4 can smoothly cut the plate. At the same time, when the electric push rod 3 pushes the shear knife 4 to move vertically downward, it can also drive the two sets of pressure rollers 204 to move downward together. When the two sets of pressure rollers 204 come into contact with the plate, due to the continued downward movement of the shear knife 4, the connecting frame 201 will slide on the outside of the vertical rod 202 and compress the spring 2 205, which can not only limit the plate to prevent the plate from warping up during shearing, but also play a buffering role to ensure that the plate can be smoothly cut. Finally, the electric push rod 3 is controlled to drive the shear knife 4 to reset to take away the sheared plate.

The guide rollers 7 and the pressure rollers 204 are on the same vertical line. The guide rollers 7 are provided to facilitate the movement of the plates on the shearing table 1, thereby saving manpower.

[0034] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
