Description

Technical Field

[0001] The utility model relates to the technical field of plate shearing machines, in particular to a plate shearing machine for automatically fixing plates. Background Art

[0002] A shearing machine is a mechanical device specially used for cutting plates. The main function of a shearing machine is to shear plates by applying pressure and using cutting blades. Its design includes a bed frame and a blade that can move up and down. By controlling the blade to descend, force is applied to the plate to break and separate the plate into the required size.

[0003] During the plate shearing process, the plate will move or deflect due to the force of the blade, thus affecting the shearing accuracy. Therefore, the plate needs to be fixed during shearing. The commonly used fixing method is that workers press the plate with both hands to fix it. Although it is simple and convenient, workers press with both hands for a long time and need to take the plate frequently, which consumes a lot of physical strength and is prone to fatigue. Moreover, when physical strength decreases, the fixing effect of pressing with both hands is poor, which easily makes the sheared plate less accurate. Utility Model Content

[0004] The utility model aims to provide a shearing machine for automatically fixing plates, which has good fixing effect and reduces the workload of workers.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A plate shearing machine for automatically fixing plates comprises a workbench.

[0007] A U-shaped frame is installed on the upper surface of the workbench, a hydraulic cylinder is installed on the upper surface of the U-shaped frame, and the end of the telescopic end of the hydraulic cylinder penetrates to the lower side of the U-shaped frame, and a cutter is installed on the end of the telescopic end of the hydraulic cylinder.

[0008] A fixed block is installed on the outer surface of the cutter, and two movable rods are arranged inside the fixed block. Top plates are installed on the upper ends of the two movable rods, and a pressure block is installed at the bottom of the two movable rods. A non-slip rubber pad is arranged at the bottom of the pressure block, and a spring is sleeved on the outer surface of the movable rod.

[0009] It can be seen that when the cutter descends to cut, the pressure block will first contact the plate and compress the spring. The elastic force of the spring pushes the pressure block tightly against the plate to fix it, thereby avoiding the displacement of the plate during the cutting process. It can be automatically fixed without the need for workers to operate, reducing the workload of workers. The anti-slip rubber pad can increase the friction between the pressure block and the plate, further improving the fixing effect. The anti-slip rubber pad has a buffering effect, which can avoid damage to the plate during fixing. The fixing block is fixed on the cutter, and the pressure block is close to the cutter, which minimizes the deformation of the plate and has a compact structure. The pressure block moves with the cutter, and the work efficiency is high.

[0010] Furthermore, both sides of the U-shaped frame are provided with slide grooves, and the outer surfaces of both sides of the cutter are connected with sliders, and the ends of the sliders pass through the slide grooves and extend to the outside thereof, and the sliders are slidably connected to the inner walls of the slide grooves.

[0011] By setting the slide groove and the sliding block, the stability of the cutter when it is raised or lowered can be improved, thereby improving the shearing effect.

[0012] Furthermore, piston cylinders are installed on the outer surfaces of both sides of the U-shaped frame, and a piston rod is arranged inside the piston cylinder, and the end of the piston rod is connected to the slider. The outer surface of the piston cylinder near its upper end is connected to a connecting head, and a hose is connected to the connecting head, and an air nozzle is installed at the end of the hose.

[0013] When the cutter descends to cut, it drives the piston rod to be pulled outward through the slider. At this time, external air enters the piston cylinder through the air nozzle. When the cutting is completed, there may be plate debris left on the surface of the workbench. When the hydraulic cylinder drives the cutter to rise, the slider drives the piston rod to move upward, and then the air inside the piston cylinder can be quickly discharged from the air nozzle to blow away the plate debris, thereby avoiding the situation where the bottom debris causes the plate to be crushed during subsequent plate shearing.

[0014] Furthermore, an adjusting block is commonly sleeved on the outer surfaces of the two movable rods, and the two ends of the spring are respectively abutted against the pressing block and the adjusting block, a screw rod passes through and is threadedly connected to the interior of the fixed block, and the end of the screw rod is rotatably connected to the upper surface of the adjusting block.

[0015] When the elasticity of the spring decreases after the device has been used for a period of time, the screw can be turned to drive the adjusting block down, thereby compressing the spring, so that the spring can obtain greater elasticity under the condition of the same compression distance, ensuring the fixing effect of the pressing block on the plate.

[0016] Furthermore, a connecting rod is connected to the outer surface of the air nozzle, and an end of the connecting rod is connected to the U-shaped frame.

[0017] By setting the connecting rod, the position of the air nozzle can be fixed to avoid the situation in which the blowing direction of the air nozzle is changed due to vibration or other reasons during use, and the debris cannot be cleared away.

[0018] Furthermore, a notch is provided on the workbench, and the notch is a rectangular structure.

[0019] When the plate is laid flat on the workbench surface, it is inconvenient to quickly pick up the plate because the hand cannot touch the bottom of the plate. By setting the notch, after the plate is cut, the hand can grab the bottom of the plate from the notch, making it convenient to pick up. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The utility model is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-3 As shown, a shearing machine for automatically fixing plates includes a workbench 100, a U-shaped frame 101 is installed on the upper surface of the workbench 100, a hydraulic cylinder 102 is installed on the upper surface of the U-shaped frame 101, and the end of the telescopic end of the hydraulic cylinder 102 passes through the lower side of the U-shaped frame 101, and a cutter 103 is installed at the end of the telescopic end of the hydraulic cylinder 102; a fixed block 104 is installed on the outer surface of the cutter 103, and two movable rods 105 are penetrated inside the fixed block 104, and the upper ends of the two movable rods 105 are both installed with top plates 106, and the bottoms of the two movable rods 105 are jointly installed with pressure blocks 107, and the bottoms of the pressure blocks 107 are provided with anti-slip rubber pads, and the outer surfaces of the movable rods 105 are sleeved with springs 108.

[0026] The hydraulic cylinder 102 drives the cutter 103 to descend to shear the plate. As the cutter 103 descends, the pressure block 107 will first contact the plate, and as the cutter 103 continues to descend, the movable rod 105 is pushed upward to the upper side of the fixed block 104 and the spring 108 is compressed. The elastic force of the spring 108 pushes the pressure block 107 to press tightly against the plate to fix it, thereby avoiding the displacement of the plate during the shearing process, and can achieve automatic fixation without the need for worker operation, thereby reducing the workload of workers.

[0027] Specifically, a slide groove 200 is provided on both sides of the U-shaped frame 101, and a slider 201 is connected to the outer surfaces of both sides of the cutter 103, and the end of the slider 201 passes through the slide groove 200 and extends to its outside, and the slider 201 is slidably connected to the inner wall of the slide groove 200. Through the setting of the slide groove 200 and the slider 201, the stability of the cutter 103 during lifting and lowering can be improved, and the shearing effect can be improved.

[0028] Specifically, piston cylinders 300 are installed on the outer surfaces of both sides of the U-shaped frame 101, and a piston rod is arranged inside the piston cylinder 300, and the end of the piston rod is connected to the slider 201. The outer surface of the piston cylinder 300 near its upper end is connected to a connector 301, and a hose 302 is connected to the connector 301. An air nozzle 303 is installed at the end of the hose 302. When the cutter 103 descends for shearing, it drives the piston rod to be drawn outward through the slider 201. At this time, external air enters the piston cylinder 300 through the air nozzle 303. When the shearing is completed, sheet metal debris may remain on the surface of the workbench 100. When the hydraulic cylinder 102 drives the cutter 103 to rise, the slider 201 drives the piston rod to move upward, and then the air inside the piston cylinder 300 can be quickly discharged from the air nozzle 303 to blow away the sheet metal debris, thereby avoiding the situation where the bottom debris causes sheet metal crushing during subsequent sheet metal shearing.

[0029] Specifically, the outer surfaces of the two movable rods 105 are jointly sleeved with an adjusting block 400, and the two ends of the spring 108 are respectively abutted against the pressing block 107 and the adjusting block 400, and the interior of the fixed block 104 is penetrated by a screw 401 and threadedly connected, and the end of the screw 401 is rotatably connected to the upper surface of the adjusting block 400. When the elasticity of the spring 108 decreases after the device has been used for a period of time, the screw 401 can be twisted, and the screw 401 can drive the adjusting block 400 to descend, thereby compressing the spring 108, so that the spring 108 can obtain greater elasticity under the same compression distance, thereby ensuring the fixing effect of the pressing block 107 on the plate.

[0030] Specifically, the outer surface of the air nozzle 303 is connected to a connecting rod 500, and the end of the connecting rod 500 is connected to the U-shaped frame 101. By setting the connecting rod 500, the position of the air nozzle 303 can be fixed to avoid the situation in which the blowing direction of the air nozzle 303 is changed due to vibration or other reasons during use, and the debris cannot be cleared away.

[0031] Specifically, a notch 600 is provided on the workbench 100, and the notch 600 is a rectangular structure. When a plate is laid flat on the surface of the workbench 100, it is inconvenient to quickly pick up the plate because the hand cannot touch the bottom of the plate. Through the setting of the notch 600, after the plate is cut, the hand can grab the bottom of the plate from the notch 600, thereby facilitating the picking up.

[0032] The above is a detailed description of the utility model in combination with specific embodiments, and it cannot be determined that the specific implementation methods of the present invention are limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, making several equivalent substitutions or obvious modifications without departing from the concept of the present invention, and having the same performance or use, should be regarded as belonging to the patent protection scope of the utility model determined by the submitted claims.
