[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The gantry shear with a material pressing structure is provided with an extrusion component group. The current gantry shear lacks a material pressing structure to press the metal plate. The loose metal plate will move or deviate during the shearing process, which will cause the metal plate to be unevenly cut and inaccurately sized, thereby reducing the practicality of the gantry shear. In the corresponding designed extrusion component group, when it is necessary to cut the metal plate on the material transport rack, the hydraulic rod is controlled and the hydraulic rod is contracted to drive the mobile rack to move downward. The downward movement of the mobile rack will drive the pressure block and the bottom plate to apply an extrusion force to the metal plate on the material transport rack, thereby making the metal plate more compact. The side frame body and the slide groove of the mobile frame are used to improve the stability of the mobile frame when it moves up and down. The bottom tooth-shaped protrusion of the bottom plate It can improve the clamping effect of the metal plate. After the metal plate is pressed, the metal plate will not shake when the gantry shear body cuts it, which makes the cut smoother. After cutting, the hydraulic rod is controlled to extend to release the squeeze on the metal plate, so that the metal plate can be moved to continue cutting. The design of this extrusion component group and the introduction of the pressing structure ensure that the metal plate remains flat and stable during cutting, reducing the possibility of position movement or offset, so the cut is smoother and the size is more accurate. The telescopic design of the hydraulic rod can quickly release the clamping of the metal plate, which is convenient for material movement and switching of work processes. The design of the tooth-shaped protrusion improves the stability of the pressing structure, ensuring that it will not loosen or offset during work.
[0014] 2. The gantry shears with a material pressing structure are provided with a shielding component group. The current gantry shears lack a protective structure. Metal chips are easily ejected from the metal plate during shearing, which will cause harm to nearby operators and equipment. In the corresponding designed shielding component group, when the cutting operation is performed, the shielding box is pushed to and released from the gantry shear body. After the release, the metal chips flying out when the gantry shear body cuts the metal plate will be blocked inside by the shielding box and the tempered glass, and will not splash onto nearby operators. After the cutting structure is completed, the shielding box can be directly pushed out through the bottom track to keep it away from the gantry shear body. At this time, the cut material can be collected. The tempered glass is mainly to ensure that the operator can view the cutting status of the gantry shear body and facilitate real-time adjustment and control. The design of this shielding component group can effectively capture and prevent metal fragments from splashing, thereby reducing the risk of injury to nearby operators and equipment. When using the gantry shears, the operator does not need to worry too much about the splashing of metal chips, so he can focus more on work and improve work efficiency.
