Description

Technical Field

[0001] The present application relates to the technical field of steel plate cut-to-length shearing, and in particular to a protective device for cutting medium and thick plates to length. Background Art

[0002] In the process of producing medium and thick plates, it is necessary to cut the medium and thick plates into specified lengths according to customer requirements. Cutting to length is usually done on a cut-to-length shear.

[0003] The cut-to-length shear generally includes a frame, a shearing part and conveying rollers. There are at least two sets of conveying rollers, which are located on both sides of the shearing part. A set of conveying rollers consists of two, which are distributed up and down and have adjustable spacing, and are used to clamp and convey medium and thick plates of different thicknesses.

[0004] During use, there have been cases where the cutting blade of the cut-to-length shears has partially broken and splashed out. Although increasing the maintenance frequency can reduce the occurrence of this situation, there are still safety risks. Therefore, a protective device is needed on the cut-to-length shears to reduce the risk of splashing out after the blade breaks. Utility Model Content

[0025] The following is combined with Figure 1-2 This application is described in further detail.

[0026] The embodiment of the present application discloses a protective device for cutting to length of medium and thick plates.

[0027] refer to Figure 1, a protective device for medium and thick plate cut-to-length shears, is used to modify the existing cut-to-length shears to increase the safety of use. It includes a frame plate 1, a bottom plate 2, a protective plate 3 and a cut-to-length shear equipment body 5. The middle part of the cut-to-length shear equipment body 5 is the shearing part. There are multiple frame plates 1, which are vertically arranged and welded to the side walls on both sides of the channel of the cut-to-length shear equipment body 5 for the plate to pass through. Two frame plates 1 form a group, and four groups are installed on the cut-to-length shear equipment body 5, with two groups distributed on both sides of the shearing part of the cut-to-length shear equipment body 5. Each group of frame plates 1 contains two, and the bottom plate 2 is welded and fixed to the bottom ends of the two frame plates 1 in each group. The protective plate 3 is inserted between the two frame plates 1 in the two opposite groups of frame plates 1. The middle part of the bottom of the protective plate 3 is extended downward. The top of the protective plate 3 is inclined upward in the direction of the shearing part of the cut-to-length shear equipment body 5. The protective plate 3 is a light-transmitting acrylic plate.

[0028] Two opposing frame plates 1 far from the shearing part of the cut-to-length device body 5 are welded and fixed with protective rods 12, and the protective rods 12 are arranged horizontally. In the two frame plates 1 of the same group, the frame plate 1 far from the shearing part of the cut-to-length device body 5 is vertically and equidistantly provided with a plurality of positioning holes 11, and the positioning holes 11 can be threadedly connected with bolts for the bottom of the protective plate 3 to abut.

[0029] By welding the frame plate 1 and the bottom plate 2 on the cut-to-length shearing equipment body 5, space is provided for the installation of the protective plate 3, and then the protective plate 3 is inserted into the position between the frame plates 1. The protective plate 3 is used to intercept the flying debris during shearing, thereby improving the safety of the equipment. The protective plate 3 is made of light-transmitting material, so the working status of the shearing part can be easily observed. The setting of the protective rod 12 can effectively improve the strength of the protective plate 3, thereby increasing the service life of the protective plate 3. The upward tilt setting of the top of the protective plate 3 can effectively intercept the top area, further improving the protective effect. The setting of the positioning hole 11 can effectively lift the protective plate 3 to adapt to the passage of medium and thick plates of different thicknesses, thereby improving the protective effect.

[0030] refer to Figure 2 The body of the cut-to-length shearing equipment is welded with a stabilizing plate 4 on both sides of the shearing part. The side wall of the stabilizing plate 4 is provided with a plurality of slots 41, and the top of the protective plate 3 is pressed against the slots 41. The stabilizing plate 4 is provided to effectively support the top of the protective plate 3, thereby improving the installation stability of the protective plate 3. After the top of the protective plate 3 is pressed against the slots 41, the protective plate 3 is pressed against one of the frame plates 1 at the same time, thereby improving the stability of the installation of the protective plate 3 and reducing the influence of the vibration of the equipment on the protective plate 3.

[0031] The implementation principle of the medium and thick plate cut-to-length shear protection device of the present application embodiment is as follows: by welding the frame plate 1, the bottom plate 2 and the stabilizing plate 4 on the frame body 5 of the cut-to-length shear equipment, and inserting the protective plate 3 between the frame plates 1, the debris that may splash out during the cut-to-length shearing process is intercepted, thereby effectively improving the safety of the cut-to-length shear equipment. The setting of the protective plate 3 against the card slot 41 can effectively improve the stability of the installation of the protective plate 3 itself, and at the same time, together with the protective rod 12, improve the safety and reliability of the protective plate 3 after installation.

[0032] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
