Description

Technical Field

[0001] The utility model relates to the technical field of metal shearing, in particular to a gantry shear used for disassembling automobiles. Background Art

[0002] In the process of recycling and reusing scrapped car frames, gantry shears are used to perform shearing operations on the scrapped car frames to improve the efficiency of car disassembly and reduce labor costs. Gantry shears are a kind of metal processing equipment, mainly used for shearing metal materials. The gantry shear adopts a door-type frame structure, which consists of an upper crossbeam, a lower crossbeam and two side columns. It has high rigidity and stability. The main structure is welded with high-quality steel. After heat treatment, it has high strength and hardness and can withstand large shearing forces. During the working process, the cutter body is driven downward by hydraulic or electric motor to shear the metal inside the frame. Since the car frame will accumulate at the bottom of the cutter body during the shearing process, if it is not moved to the outside of the cutter body in time, it will easily affect the subsequent downward shearing of the cutter body. Therefore, it is necessary to move the sheared metal.

[0003] In the related art, when using a gantry shear, an inclined material guide seat is generally installed inside the frame at the bottom of the cutter body to guide the sheared material obliquely so that the sheared material moves out of the bottom of the cutter body.

[0004] However, during the current use of the gantry shears, due to the limited guiding range of the inclined material guide seat, if the material accumulated on the front side of the material guide seat is transferred in time, the material that subsequently falls to the top of the material guide seat will be difficult to move forward and will still accumulate at the bottom of the cutter body, affecting the operation of the cutter body, resulting in cumbersome material shearing movement, affecting the convenience and stability of material shearing movement.

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1-4 The utility model provides a technical solution: a gantry shear for automobile dismantling, comprising a gantry shear body 1 and a material pushing mechanism, a knife body 2 is installed on the front side of the interior of the gantry shear body 1, and a material guide seat 3 is installed on the bottom of the interior of the gantry shear body 1. When the gantry shear body 1 is used in conjunction with the knife body 2, a thrust for moving forward can be applied to the automobile frame metal after shearing by the knife body 2, so that the material located in front of the material guide seat 3 moves forward, providing space for the metal guided by the guide seat after subsequent shearing by the knife body 2 to move forward, avoiding the situation where the metal accumulates at the bottom of the knife body 2 after shearing, interfering with the subsequent shearing work of the knife body 2, thereby improving the convenience and stability of material shearing movement.

[0032] Reference Figures 1-4In a preferred embodiment, the material pushing mechanism includes a connecting rod 4, which is movably connected to both sides of the front side of the cutter body 2, a fixed plate 5 is fixedly connected to the rear side of the bottom of the connecting rod 4, and a movable plate 6 is movably connected to the rear side of the top of the connecting rod 4, a lifting rod 7 is movably connected to the front side of the connecting rod 4, and a pushing plate 8 is fixedly connected to the bottom of the lifting rod 7. A force seat 9 is fixedly connected to the bottom of the front side of the gantry shear body 1 by bolts, and the tops of both sides of the pushing plate 8 are fixedly connected to a force frame 10 in contact with the force seat 9, connecting the force mechanism It is arranged inside the movable plate 6, and the movable plate 6 cooperates with the fixed plate 5 to install and connect the connecting rod 4 and the cutter body 2, so that the lifting rod 7 connects the push plate 8 to the cutter body 2 through the connecting rod 4, and the force seat 9 is connected to the gantry shear body 1 through the bolt. When the cutter body 2 moves downward to shear the car frame inside the gantry shear body 1, the connecting rod 4 drives the push plate 8 to move downward through the lifting rod 7 and contacts the metal after shearing on the front side of the gantry shear body 1. At this time, the force frame 10 moves downward with the push plate 8. After the bottom of the force frame 10 contacts the top of the force seat 9, since the force frame 10 and the force seat 9 are in contact with each other at an inclined surface, as the force frame 10 moves downward with the push plate 8, it applies a moving force to the push plate 8 to the front side, pushing the material after shearing at the front side of the gantry shear body 1, and providing a guiding movement space for the material guided by the subsequent guide seat. The connecting force mechanism includes a connecting hole 11, a connecting frame 12, a screw groove 13 and a screw rod 14. The connecting hole 11 is opened inside the movable plate 6, and the connecting frame 12 is movably connected to the connecting hole 1 1, a screw groove 13 is opened on the rear side of the top of the connecting rod 4, and the screw 14 is threadedly connected to the inside of the screw groove 13. The top of the screw 14 is fixedly connected to the bottom of the connecting frame 12. When the movable plate 6 is used with the connecting rod 4, the user can provide a medium for the actual connection and tightening force of the movable plate 6, and perform force connection between the movable plate 6 and the connecting rod 4, avoiding the situation that it is difficult for the movable plate 6 to cooperate with the fixed plate 5 to connect the connecting rod 4 and the blade body 2 stably when in use, thereby improving the connection force effect of the movable plate 6.

[0033] Reference Figure 3The lifting and lowering of the movable plate 6 is achieved by rotating the screw 14 and the screw 14, so that the movable plate 6 and the connecting rod 4 can be lifted and lowered.

[0034] Reference Figure 3 When the telescopic rod 20 is used in conjunction with the lifting rod 7, the telescopic rod 20 is applied to the lifting rod 7 to apply a reset pulling force to the lifting rod 7 to move backward, so as to avoid the situation that the lifting rod 7 is difficult to drive the pushing plate 8 to return to its original position when the lifting plate 8 is used.

[0035] Reference Figure 2The outer side of the slider 28 is fixedly connected to the inner wall of the expansion slot 23, and the spring 26 is provided inside the push groove 25. One end of the spring 26 is fixedly connected to the inner wall of the expansion slot 23, and the other end of the spring 26 is fixedly connected to the inner wall of the push groove 25. When the pushing plate 8 is used in conjunction with the cutter body 2, the downward contact range of the pushing plate 8 is expanded to avoid the pushing plate 8 from having difficulty in contacting the material on the front side of the material guide seat 3 during operation, resulting in the inability to push the material, thereby improving the pushing effect of the pushing plate 8. Both sides of the expansion plate 24 are provided with a slide groove 27, and the top of the slide groove 27 is slidably connected to a slider 28. The outer side of the slider 28 is fixedly connected to the inner wall of the expansion slot 23. When the spring 26 is used in conjunction with the expansion plate 24, the expansion plate 24 can be slidably limited between the expansion slot 23 to avoid the expansion plate 24 from being separated from the expansion slot 23 during use, thereby improving the working stability of the expansion plate 24.

[0036] Specifically, the working process or working principle of the gantry shears for automobile disassembly is as follows: when in use, the connecting rod 4 is first moved to the front side of the cutter body 2, and the protruding horizontal plate position on the surface of the cutter body 2 is in contact with the connecting rod 4 and located on the inner side of the movable plate 6 and the fixed plate 5, and then the screw rod 14 is rotated by hand to match the screw groove 13, and a downward moving force is applied to the movable plate 6 through the connecting frame 12 and the connecting hole 11, so that the movable plate 6 cooperates with the fixed plate 5 to clamp and connect the connecting rod 4 and the cutter body 2, prompting the lifting rod 7 and the pushing plate 8 to be located in front of the cutter body 2. On the side, in preparation for the subsequent pushing of the material located in front of the material guide seat 3, during this process, the lifting column 16 follows the movable plate 6 to move inside the lifting hole 15, and performs lifting and connecting work between the movable plate 6 and the connecting rod 4. At the same time, the limiting ring 17 cooperates with the limiting disk 18 to limit the range between the movable plate 6 and the connecting rod 4 during the lifting process through the lifting column 16, and then the force seat 9 is installed at the bottom of the front side of the gantry shear body 1 through the bolts, in preparation for the subsequent application of forward force to the push plate 8 by the force frame 10. When the cutter body 2 moves downward to the gantry When the car frame inside the shear body 1 is shearing, the connecting rod 4 drives the push plate 8 to move downward through the lifting rod 7. At this time, the expansion plate 24 that is protruding from the expansion slot 23 under the thrust of the spring 26 contacts the sheared metal on the front side of the guide seat 3. At the same time, the slider 28 cooperates with the slide groove 27 to perform a sliding connection and limit work between the expansion plate 24 and the expansion slot 23. In this process, the force frame 10 moves downward with the push plate 8. When the bottom of the force frame 10 contacts the top of the force seat 9, the force frame 10 and the force seat 9 are tilted. The inclined surfaces contact, and as the force-applying frame 10 follows the push plate 8 to move downward, it applies a moving force to the push plate 8 toward the forward side, so that the push plate 8 cooperates with the expansion plate 24 to push the material sheared in front of the material guide seat 3, providing a guiding movement space for the material guided by the subsequent guide seat, so that the material sheared by the cutter body 2 moves downward and is guided to the forward side through the material guide seat 3. During the process, the telescopic rod 20 follows the connecting rod 4 to move forward inside the telescopic slot 19, and pulls the tension spring 22 to extend forward, preparing for the subsequent pulling of the lifting rod 7 and the push plate 8 to reset.

[0037] It should be noted that the gantry shear body 1, the blade body 2 and the material guide seat 3 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
