Description

Technical Field

[0001] The utility model relates to the technical field of metal plate processing, in particular to a self-adjusting plate shearing machine. Background Art

[0002] A shearing machine is a mechanical device used to shear metal materials (such as steel and aluminum). It is primarily used to cut large metal sheets into the desired size. Its working principle is to cut the material into shape through the relative motion of the blades. The main types are divided into mechanical shears: using a mechanical transmission system to shear the blades via a crank or gear; hydraulic shears: using a hydraulic system to drive the blades, with higher shearing force and precision, suitable for processing thick plates; electric shears: driven by an electric motor, suitable for shearing small and thin plates. Applied in the metalworking and construction industries: used in the production of steel structures, fences, automobiles, and other industries, shears play an important role in metalworking, improving production efficiency and processing accuracy.

[0003] When existing shearing machines are used to shear metal plates of different thicknesses, workers are required to make adjustments before starting, and they cannot make adjustments by themselves. If workers neglect to make adjustments, when reducing the thickness of thinner metal plates, the auxiliary clamping force may be too large, causing deformation of the metal plates, which may cause uneven shearing edges, burrs or notches, and ultimately affect the processing quality of the metal plates.

[0004] Therefore, it is urgent to provide a self-adjusting shearing machine to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the shortcomings of the above-mentioned prior art and provide a self-adjusting shearing machine.

[0006] In order to solve the above technical problems, a technical solution adopted by the present invention is as follows: a self-adjusting shearing machine is provided, comprising a support frame, a wheel pulley assembly is installed on the top of the support frame, and a moving mechanism is installed on the top of the support frame and at the center of the wheel pulley assembly;

[0007] The moving mechanism is provided with a fixing mechanism, a cutting table is fixedly connected to one side of the top of the support frame, and a mounting frame is fixedly connected to one side of the top of the support frame and close to the top of the cutting table;

[0008] A clamping mechanism is installed on one side of the top of the mounting frame, a shearing mechanism is installed on the other side of the top of the mounting frame, and a metal plate is provided on the top of the wheel skating assembly.

[0009] The utility model is further configured as follows: the moving mechanism includes two slide rails fixedly connected to the top of the support frame, the top of the support frame and close to the two slide rails are fixedly connected with racks, the two slide rails are slidably connected with fixed seats, the front end centers of the two fixed seats are fixedly installed with motors, the outer walls of the two motor output shafts are fixedly connected with gears, and the two gears are respectively engaged with corresponding racks.

[0010] Through the above technical solution, when the fixing mechanism clamps the metal plate and needs to be fed and sheared, the motor is started. The motor drives the gear to rotate through the output shaft, and the gear engages and rotates on the corresponding rack, thereby driving the fixing seat to move to one side, thereby realizing automatic feeding of the metal plate, eliminating the need for manual feeding and achieving high efficiency.

[0011] The utility model is further configured as follows: the fixing mechanism includes two connecting seats, the two connecting seats are respectively fixedly connected to the top of the fixing seat, the two connecting seats are threadedly connected to a threaded rod, the bottom ends of the two threaded rods are rotatably connected to a clamping plate, and the top ends of the two threaded rods are fixedly connected to a handwheel.

[0012] Through the above technical solution, when clamping the metal plate, the staff places the metal plate on the pulley assembly, places one side of it on two fixed seats and aligns it, turns the handwheel, drives the threaded rod connected to it to rotate, thereby driving the clamping plate to move downward, clamping the metal plate on the fixed seat, and facilitating subsequent automatic feeding.

[0013] The utility model is further configured as follows: one side of the front end of the two fixing seats is fixedly connected to a connecting frame, the front ends of the two connecting frames are fixedly installed with a cylinder, and one end of the two cylinder pistons is fixedly connected to a magnetic block.

[0014] Through the above technical solution, before the metal plate is clamped, the cylinder is started to drive the magnetic blocks connected to it to move to the same horizontal position. The two magnetic blocks are attracted to one side of the metal plate, which makes it convenient to place the metal plate neatly and prevents the metal plate from being offset when clamped, thereby improving the subsequent alignment and shearing accuracy. After the shearing of the metal plate is completed, the two magnetic blocks are reset, and the staff loosens the handwheel to quickly unload the material, which is simple to operate.

[0015] The utility model is further configured as follows: two laser sensors are installed on one side of the mounting frame.

[0016] Through the above technical solution, when the metal plate is sent to the position below the two laser sensors, the two laser sensors start working to measure the thickness of the metal plate. According to the thickness, they know how much pressure to apply to it to prevent the metal plate from being deformed due to excessive pressure, and to prevent the metal plate from being offset during shearing due to insufficient pressure. The two laser sensors transmit the information to the clamping mechanism.

[0017] The utility model is further configured as follows: the clamping mechanism includes a plurality of first hydraulic cylinders fixedly connected to one side of the top of the mounting frame, a movable frame fixedly connected between the bottom ends of the plurality of first hydraulic cylinder pistons, a plurality of evenly distributed limit rods slidably connected to the movable frame, a fitting plate fixedly connected between the bottom ends of the plurality of limit rods, and springs sleeved on the outer sides of the plurality of limit rods.

[0018] Through the above technical solution, when the metal plate moves to the position below the laminating plate, multiple first hydraulic cylinders are started, and the multiple first hydraulic cylinders push the movable frame through the piston, so that the movable frame pushes multiple springs, thereby pushing the laminating plate to laminarize the metal plate on the cutting table, making it convenient for the subsequent shearing mechanism to align and shear, and at the same time preventing the metal plate from moving during the shearing process, thereby improving the cutting accuracy.

[0019] The utility model is further configured as follows: the shearing mechanism includes a plurality of second hydraulic cylinders fixedly connected to the other side of the top of the mounting frame, a cutter is fixedly connected between the bottom ends of the plurality of second hydraulic cylinder pistons, and one side of the cutter is in contact with one side of the laminating plate.

[0020] Through the above technical solution, when shearing the metal plate, multiple second hydraulic cylinders are started, and the multiple second hydraulic cylinders push the cutter through the piston, so that the cutter cuts the metal plate downward, and the cutter remains parallel to the laminating plate and one side of the cutting table.

[0021] The beneficial effects of the utility model are as follows:

[0022] 1. This utility model uses laser sensors and a clamping mechanism. The two laser sensors can measure the thickness of the metal plate before cutting. Based on the thickness, the amount of pressure to be applied can be determined. This prevents excessive pressure from causing deformation of the metal plate and insufficient pressure from causing displacement of the metal plate during shearing, thereby greatly improving the shearing accuracy of the metal plate.

[0023] 2. The utility model uses a moving mechanism and a fixing mechanism to first suck the metal plate through two magnetic blocks before clamping it, which is convenient for the staff to clamp it horizontally and prevent the metal plate from shifting during the clamping process, affecting the subsequent shearing quality.

[0031] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0032] See also Figures 1-6 The two gears 305 are meshed with the corresponding racks 302, and then the fixed seat 303 is driven to move to one side, so that the metal plate 10 can be automatically fed to the workpiece 10 by the fixing means 304.

[0033] like Figure 1-4As shown, the mobile mechanism 3 is provided with a fixing mechanism 4, which includes two connecting seats 401, and the two connecting seats 401 are respectively fixedly connected to the top of the fixing seat 303, and the two connecting seats 401 are both threadedly connected with a threaded rod 402, and the bottom ends of the two threaded rods 402 are rotatably connected to the clamping plate 403, and the top ends of the two threaded rods 402 are fixedly connected to the handwheel 404. When clamping the metal plate 10, the staff places the metal plate 10 on the roller skate assembly 2, places one side of the metal plate 10 on the two fixing seats 303 and aligns them, and rotates the handwheel 404 to drive the threaded rod 402 connected thereto to rotate, thereby driving the clamping plate 403 to move downward, clamping the metal plate 10 on the fixing seat 3 03, to facilitate subsequent automatic feeding, the front end side of the two fixed seats 303 is fixedly connected to the connecting frame 405, the front end of the two connecting frames 405 are fixedly installed with cylinders 406, and one end of the pistons of the two cylinders 406 is fixedly connected to the magnetic block 407. Before the metal plate 10 is clamped, the cylinder 406 is started to drive the magnetic block 407 connected thereto to move to the same horizontal position. The two magnetic blocks 407 suck on one side of the metal plate 10, which is convenient for arranging the metal plate 10 neatly and preventing the metal plate 10 from being offset when clamping, thereby improving the subsequent alignment and shearing accuracy. After the shearing of the metal plate 10 is completed, the two magnetic blocks 407 are reset, and the staff loosens the handwheel 404 to quickly unload the material, which is simple to operate.

[0034] like Figure 1-5 As shown, two laser sensors 7 are installed on one side of the mounting frame 6. When the metal plate 10 is sent to the position below the two laser sensors 7, the two laser sensors 7 start to work and measure the thickness of the metal plate 10. According to the thickness, it is known how much pressure to apply to it to prevent the metal plate 10 from being deformed due to excessive pressure, and to prevent the metal plate 10 from being offset during shearing due to insufficient pressure. The two laser sensors 7 transmit the information to the clamping mechanism 8.

[0035] like Figure 1-6As shown, a cutting table 5 is fixedly connected to one side of the top of the support frame 1, a mounting frame 6 is fixedly connected to one side of the top of the support frame 1 and close to the top of the cutting table 5, a clamping mechanism 8 is installed on one side of the top of the mounting frame 6, and the clamping mechanism 8 includes a plurality of first hydraulic cylinders 801 fixedly connected to one side of the top of the mounting frame 6, a movable frame 802 is fixedly connected between the bottom ends of the pistons of the plurality of first hydraulic cylinders 801, a plurality of evenly distributed limiting rods 803 are slidably connected to the movable frame 802, and the bottom ends of the plurality of limiting rods 803 are fixedly connected between each other. There is a laminating plate 804, and springs 805 are sleeved on the outer sides of multiple limit rods 803. When the metal plate 10 moves to the position below the laminating plate 804, multiple first hydraulic cylinders 801 are started, and multiple first hydraulic cylinders 801 push the movable frame 802 through the piston, so that the movable frame 802 pushes multiple springs 805, thereby pushing the laminating plate 804 to laminarize the metal plate 10 on the cutting table 5, making it convenient for the subsequent shearing mechanism 9 to align and shear, and at the same time preventing the metal plate 10 from moving during the shearing process, thereby improving the cutting accuracy.

The shearing mechanism 9 includes a plurality of second hydraulic cylinders 901 fixedly connected to the other side of the top of the mounting frame 6, and a cutter 902 is fixedly connected between the bottom ends of the pistons of the plurality of second hydraulic cylinders 901. One side of the cutter 902 is in contact with one side of the laminating plate 804. When shearing the metal plate 10, the plurality of second hydraulic cylinders 901 are started, and the plurality of second hydraulic cylinders 901 push the cutter 902 through the piston, so that the cutter 902 cuts the metal plate 10 downward, and the cutter 902 remains parallel to the laminating plate 804 and one side of the cutting table 5.

[0037] When the utility model is in use, the two cylinders 406 are started to drive the magnetic blocks 407 connected thereto to move to the same horizontal position. The staff places the metal plate 10 on the wheel pulley assembly 2, places one side of the metal plate 10 on the two fixing seats 303, and sucks one side of the outer wall of the metal plate 10 through the two magnetic blocks 407. The hand wheel 404 is turned to drive the threaded rod 402 connected thereto to rotate, thereby driving the clamping plate 403 to move downward, clamping the metal plate 10 on the fixing seat 303, and then starting the motor 304. The motor 304 rotates through the output shaft to drive the gear 305 to rotate. The gear 305 engages and rotates on the corresponding rack 302, thereby driving the fixing seat 303 to move to one side. When the metal plate 10 is sent to the two laser sensors, the gear 305 is engaged and rotated. When the metal plate 10 is moved to the lower position of the sensor 7, the two laser sensors 7 start to work and measure the thickness of the metal plate 10. The two laser sensors 7 transmit the information to the clamping mechanism 8. When the metal plate 10 moves to the lower position of the bonding plate 804, multiple first hydraulic cylinders 801 are started. Multiple first hydraulic cylinders 801 push the movable frame 802 through the piston, so that the movable frame 802 pushes multiple springs 805, thereby pushing the bonding plate 804 to bond the metal plate 10 to the cutting table 5, and then multiple second hydraulic cylinders 901 are started.
