Abstract
Description
Technical Field
[0001] This utility model relates to the field of gantry shearing machines, and in particular to a precision cutting gantry shearing machine. Background Technology
[0002] The gantry shear is a widely used shearing equipment in scrap metal recycling, metallurgy, and machining. With its high stability and powerful shearing force thanks to its gantry frame structure, it can efficiently cut various metal materials such as steel plates, reinforcing bars, scrap steel, and scrap iron. It is one of the core pieces of equipment in material reduction and resource recycling. This equipment typically consists of a gantry frame, a drive hydraulic cylinder, shearing blades, a worktable, and a material fixing structure. The hydraulic cylinder drives the shearing blades to reciprocate up and down, working in conjunction with the worktable to complete the shearing operation. It boasts advantages such as high shearing efficiency and a wide range of applicable materials.
[0003] Traditional gantry shears generally have design limitations in their material fixing structures. Their fixing components often only act at a single point near the shearing area, limiting and fixing only the material at the shearing contact point. When the material to be sheared is long, the end furthest from the shearing area will be suspended or free without effective restraint. During the shearing process, the material is prone to deflection, slippage, and other displacement due to uneven force. This not only causes uneven cuts and excessive dimensional deviations, significantly reducing cutting accuracy, but also may lead to abnormal force on the shearing blade due to material displacement, thus affecting the equipment's lifespan and even posing certain production safety hazards. Utility Model Content
[0004] The main objective of this invention is to provide a gantry shearing machine for precise cutting, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A precision cutting gantry shearing machine includes a gantry frame, on which a fixing component is fixedly installed. A shearing worktable is fixedly installed on the lower inner wall of the gantry frame, below the fixing component. An auxiliary fixing component is fixedly installed at the rear end of the fixing component. The auxiliary fixing component consists of a connecting frame and a fixing pressure plate. There are two connecting frames, which are symmetrically fixedly installed on the upper end of the fixing pressure plate. An auxiliary worktable is fixedly installed at the rear end of the shearing worktable. Two limiting components are symmetrically fixedly installed on the auxiliary worktable. The limiting components consist of a limiting hydraulic cylinder, a support rod, and a limiting plate. The support rod is fixedly installed on the piston rod of the limiting hydraulic cylinder, and the limiting plate is fixedly installed on the upper end of the support rod.
[0006] Preferably, a first hydraulic cylinder is fixedly installed on the upper side wall of the gantry frame, and a shearing component is slidably installed on the inner side of the gantry frame, the shearing component being fixedly connected to the piston rod of the first hydraulic cylinder.
[0007] Preferably, the fixing component is located behind the first hydraulic cylinder and the shearing member. The fixing component consists of a second hydraulic cylinder and a fixing block. The second hydraulic cylinder is fixedly installed on the upper side wall of the gantry frame, and the shearing member is slidably installed on the inner side of the gantry frame.
[0008] Preferably, the connecting bracket on the auxiliary fixing member is fixedly installed on the rear end of the fixing block by bolts, and the lower end of the fixing plate is flush with the lower end of the fixing block.
[0009] Preferably, the auxiliary workbench consists of a support plate and a support frame. The support frame is fixedly installed at the lower end of the support plate and at the rear end of the shearing workbench by bolts. The upper end of the support plate is flush with the upper end of the shearing workbench, and two guide rail grooves are symmetrically provided on the support plate.
[0010] Preferably, the limiting hydraulic cylinder on the limiting assembly is fixedly installed at the lower end of the support plate, the support rod is movably installed in the guide rail groove, and the limiting plate is movably installed at the upper end of the support plate.
[0011] Compared with the prior art, the present invention has the following beneficial effects: By setting auxiliary fixing components on the fixed assembly, an auxiliary worktable on the shearing table, and limiting components on the auxiliary worktable, the fixing blocks of the fixed assembly can be used to mainly fix the material near the shearing area, while the fixing plates of the auxiliary fixing components can simultaneously and auxiliaryly fix the rear end of the material near the shearing area. This achieves dual fixation of the material to be sheared. At the same time, the auxiliary worktable can stably support long materials. The limiting hydraulic cylinders in the two limiting components drive the limiting plates to move, and the distance between the two limiting plates can be adjusted according to the width of the material to laterally limit the extension of the material. Ultimately, this prevents the material from deflecting or slipping during the cutting process, greatly improving the cutting accuracy, ensuring a flat cut and accurate cutting dimensions. It also avoids abnormal stress on the shearing components due to material displacement, extends the service life of the equipment, reduces production safety hazards, and improves the overall stability and safety of the cutting operation.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0015] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a precision cutting gantry shearing machine includes a gantry frame 1, a fixing assembly 2 fixedly installed on the gantry frame 1, and a shearing worktable 3 fixedly installed on the lower inner wall of the gantry frame 1 below the fixing assembly 2. An auxiliary fixing component 4 is fixedly installed at the rear end of the fixing assembly 2. The auxiliary fixing component 4 consists of a connecting frame 11 and a fixing pressure plate 12. There are two connecting frames 11, symmetrically fixedly installed on the upper end of the fixing pressure plate 12. An auxiliary worktable 5 is fixedly installed at the rear end of the shearing worktable 3. Two limiting components 6 are symmetrically fixedly installed on the auxiliary worktable 5. The limiting components 6 consist of a limiting hydraulic cylinder 16, a support rod 17, and a limiting plate 18. The support rod 17 is fixedly installed on the piston rod of the limiting hydraulic cylinder 16, and the limiting plate 18 is fixedly installed on the upper end of the support rod 17. By setting the auxiliary fixing component 4 on the fixing assembly 2 and the auxiliary worktable 5 on the shearing worktable 3, the machine can achieve precise cutting. The auxiliary worktable 5 is equipped with limiting components 6, which can not only use the fixing blocks 10 of the fixing components 2 to mainly fix the material near the shearing area, but also use the fixing plates 12 of the auxiliary fixing components 4 to simultaneously fix the rear part of the material away from the shearing area, thus achieving dual fixation of the material to be sheared. At the same time, the auxiliary worktable 5 can stably support long materials. The limiting hydraulic cylinders 16 in the two limiting components 6 drive the limiting plates 18 to move, and can adjust the distance between the two limiting plates 18 according to the width of the material to laterally limit the extension of the material, ultimately preventing the material from deflecting or slipping during the cutting process. This greatly improves the cutting accuracy of the material, ensures a flat cut and accurate cutting dimensions, and also avoids abnormal stress on the shearing components 8 due to material displacement, extending the service life of the equipment, reducing production safety hazards, and improving the overall stability and safety of the cutting operation.
[0016] Specifically, a first hydraulic cylinder 7 is fixedly installed on the upper side wall of the gantry frame 1. A shearing component 8 is slidably installed on the inner side of the gantry frame 1, and the shearing component 8 is also fixedly connected to the piston rod of the first hydraulic cylinder 7. The fixing assembly 2 is located behind the first hydraulic cylinder 7 and the shearing component 8. The fixing assembly 2 consists of a second hydraulic cylinder 9 and a fixing block 10. The second hydraulic cylinder 9 is fixedly installed on the upper side wall of the gantry frame 1, and the shearing component 8 is slidably installed on the inner side of the gantry frame 1. The connecting bracket 11 on the auxiliary fixing component 4 is fixedly installed on the rear end of the fixing block 10 by bolts. The lower end of the fixing plate 12 is flush with the lower end of the fixing block 10. The auxiliary worktable 5 consists of a support plate 13 and... The support frame 14 is fixedly installed at the lower end of the support plate 13 and bolted to the rear end of the shearing table 3. The upper end of the support plate 13 is flush with the upper end of the shearing table 3. Two guide rail grooves 15 are symmetrically opened on the support plate 13. The limiting hydraulic cylinder 16 on the limiting assembly 6 is fixedly installed at the lower end of the support plate 13. The support rod 17 is movably installed in the guide rail groove 15. The limiting plate 18 is movably installed at the upper end of the support plate 13. The method of using this precision cutting gantry shear to cut long materials is as follows: First, place the long material to be cut on the upper end of the shearing table 3 and the auxiliary worktable 5, so that the material is in the two limiting positions. Between the two limiting plates 18 on the positioning component 6, and according to the required cutting length, the material position is adjusted so that the corresponding length of the front part of the material protrudes beyond the front end of the shearing worktable 3. Before cutting begins, the two limiting hydraulic cylinders 16 on the auxiliary worktable 5 are operated to move the support rod 17 within the guide rail groove 15, thereby driving the two limiting plates 18 to horizontally clamp the material. Then, the second hydraulic cylinder 9 in the fixing component 2 is activated to push the fixing block 10 downward. At the same time, the auxiliary fixing part 4 at the rear end of the fixing block 10 also moves downward. The fixing block 10 and the fixing plate 12 are used to squeeze and fix the material on the upper end of the shearing worktable 3 and the auxiliary worktable 5, completing the process. After the material is double-fixed, the first hydraulic cylinder 7 on the gantry 1 is activated, which drives the shearing piece 8 to move down and cut the part of the material protruding from the front end of the shearing table 3. After the cutting is completed, the first hydraulic cylinder 7 is controlled to drive the shearing piece 8 to reset, and then the second hydraulic cylinder 9 and the limit hydraulic cylinder 16 are controlled in sequence to make the fixing block 10 and the fixing plate 12 reset upward to release the material, and the two limit plates 18 are moved away from each other to release the material, thereby releasing the fixation of the material. Then, according to the required cutting length, the material is pushed forward by the corresponding length. The above clamping, fixing and cutting steps are repeated to complete the continuous and precise cutting operation of long materials.
[0017] It should be noted that the length of the support plate 13 in the auxiliary workbench 5 can be flexibly set according to actual usage needs. When the material to be cut daily is long, a longer support plate 13 can be selected to stably support the material and prevent it from sagging due to excessive length, ensuring the overall horizontal state of the material. When the material to be cut daily is short, a shorter support plate 13 can be used to save installation space. The length of the fixed pressure plate 12 must match the width of the support plate 13, so that the fixed pressure plate 12 can assist in fixing the material as it moves down with the fixed pressure block 10. The timing ensures that the coverage area of the fixed pressure plate 12 corresponds to the bearing area of the support plate 13, so that the material on the auxiliary workbench 5 is subjected to uniform downward pressure and fixing force, ensuring the effect of auxiliary fixing. When the material is fixed, the limiting plate 18 will be in the area between the shearing workbench 3 and the fixed pressure plate 12. This position can accurately limit the lateral displacement of the material, which will not interfere with the downward pressure and fixing of the material by the fixed pressure block 10 and the fixed pressure plate 12, and will also prevent the material from shifting to both sides when the shearing piece 8 is cutting, ensuring the accuracy of cutting.
[0018] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
