Technical Field
[0001] The utility model relates to the technical field of metal cutting, in particular to a shearing device. Background Art
[0002] Metal sheet is a rectangular metal plate with a certain thickness and width, usually made of iron, steel, aluminum and other metals. Metal sheet is widely used in many industries such as construction, decoration, automobile, shipbuilding, aviation, electronics, machinery, etc. It can be used as structural parts, covering parts, decorative parts, etc. The processing methods of metal sheet include shearing, bending, stamping, cutting, etc., among which shearing is a more common method.
[0003] In the prior art, when a metal sheet is sheared by a shearing device, at the shearing position, the side of the metal sheet close to the cutter is prone to tilt up and down due to the cutting movement and extrusion of the cutter, which eventually causes deformation of the metal sheet at the shearing position, bringing difficulties to subsequent processing and increasing manual labor intensity. For this purpose, a shearing device is designed. Utility Model Content

Detailed Embodiments
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0019] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
[0020] Referring to Figures 1 - 3 , a shearing device includes a workbench 1. A U-shaped support frame 3 is fixedly connected to the middle position at the top of the workbench 1. Rectangular frames 5 are fixedly connected to both sides near the top inside the U-shaped support frame 3. Slide bars 501 are fixedly connected between the top and bottom of both ends inside the two rectangular frames 5. The same first T-shaped block 6 is slidably sleeved on the circumferential surfaces of the two slide bars 501 on the same side at different rectangular frames 5. Circular holes adapted to the slide bars 501 are opened at both ends of the first T-shaped block 6. The same second T-shaped block 7 is slidably connected to the circumferential surfaces of the other two slide bars 501. Circular holes adapted to the slide bars 501 are opened at both ends of the second T-shaped block 7. A spring 502 is sleeved at the bottom of each slide bar 501. A first rack 8 is fixedly connected to the side of the second T-shaped block 7 close to the first T-shaped block 6. A second rack 9 is fixedly connected to the side of the first T-shaped block 6 close to the second T-shaped block 7.
[0021] In this embodiment, an electric push rod 4 is fixedly connected to the top of the U-shaped support frame 3. The output end at the bottom of the electric push rod 4 penetrates through the U-shaped support frame 3 and is fixedly connected to a push plate 401. Two vertical plates 402 are fixedly connected to the bottom of the push plate 401. A gear 403 is rotatably connected to the bottom of the two vertical plates 402 through a rotating shaft.
[0022] In this embodiment, the gear 403 meshes with the first rack 8 and the second rack 9 respectively. Through the settings of the gear 403, the first rack 8 and the second rack 9, the first T-shaped block 6 and the second T-shaped block 7 can rise and fall synchronously and can also be adjusted relative to each other.
[0023] In this embodiment, a pressing plate 601 is fixedly connected to the bottom of the first T-shaped block 6, and a strip-shaped perforation 602 is opened on the pressing plate 601. A cutting knife 701 is fixedly connected to the bottom of the second T-shaped block 7, and the cutting knife 701 is adapted to the strip-shaped perforation 602, and the cutting knife 701 can pass through the strip-shaped perforation 602.
[0024] In this embodiment, a support platform 2 is fixedly connected to the middle of the top of the workbench 1. Rectangular holes 201 are opened at both ends of the support platform 2. A plurality of rollers 203 are rotatably connected between both ends of the two rectangular holes 201. With the setting of the rollers 203, it is relatively easy to load and unload metal plates.
[0025] In this embodiment, a strip hole 202 is opened in the middle of the top of the support platform 2, and the strip hole 202 is compatible with the cutter 701. When the cutter 701 is cutting, the setting of the strip hole 202 ensures that the support platform 2 will not hinder the cutting of the cutter 701.
[0026] Working principle: A shearing device, when in use, the metal sheet to be cut is placed on the support table 2, and the roller 203 is set to facilitate the sliding of the metal sheet on the support table 2, so that loading and unloading are more labor-saving. When the metal sheet is placed in the right position, the electric push rod 4 is started, so that the push plate 401 brings the vertical plate 402 and the gear 403 down, and the second T-block 7 and the first T-block 6 are driven to descend together through the gear 403, and the spring 502 is compressed. When the pressure plate 601 contacts the metal sheet, the gear 403 will rotate, so that the first T-block 601 is pressed down and the second T-block 7 is pressed down. The second T-block 7 descends with the cutter 701. As the electric push rod 4 continues to extend, the pressure plate 601 always presses the metal sheet tightly, and the cutter 701 will cut the metal sheet. When the cutter 701 descends, due to the rotation of the gear 403, the pressure plate 601 always presses the metal sheet, so that when the cutter 701 is cutting, the metal sheet will not be warped up at the cutting point. Until the cutting is completed, the electric push rod 4 is reset. Under the action of multiple springs 502, the second T-block 7 and the first T-block 6 will still be at the same height.
[0027] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below".
