Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic shearing machines, in particular to a hydraulic shearing machine. Background Art

[0002] A hydraulic shearing machine is a machine that uses a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap to apply shear force to metal plates of various thicknesses, so that the plates are broken and separated according to the required size. Although the existing device can quickly unload the cut plates during use, the device has a poor fixing effect during the cutting process of the plates during actual use, which makes the device easy to deviate during the actual cutting process, thereby reducing the cutting quality.

[0003] As disclosed in Chinese patent announcement No. CN218362351U, a new type of hydraulic shearing machine is disclosed. When in use, the worker first places the plate to be cut on the top of the workbench, and then the worker manually pushes the plate forward. When the front end of the plate is pushed to the appropriate position, the worker turns on the cylinder to drive the connecting plate to move downward, so that the lower fixing block arranged under the eight-shaped fixing plate fixes the plate. After the fixing is completed, the servo motor is turned on, and the threaded rod is driven to rotate by the servo motor. When the threaded rod rotates and the L-shaped front end fixing plate arranged outside moves forward, the L-shaped front end fixing plate fixes the front end of the plate. After the fixing is completed, the hydraulic cylinder is turned on, so that the hydraulic cylinder drives the cutting knife to move downward, and then the plate is sheared. During the shearing process, the slider moves inside the slide groove, so as to position the cutting knife to prevent the cutting knife from shifting. After the cutting is completed, the L-shaped front end fixing plate is moved backward, so that the cut plate falls into the aggregate box.

[0004] However, the new hydraulic shearing machine in the above application requires manual manpower to push the plates, which is time-consuming and labor-intensive when facing heavier plates, increasing the physical exertion of the staff, and the plates may become skewed during the manual pushing process. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a kind of hydraulic shearing machine. Utility Model Content

[0006] The purpose of the utility model is to provide a hydraulic shearing machine to solve the problem that the new hydraulic shearing machine proposed in the above background technology requires manual manpower to push the plate, which is time-consuming and labor-intensive when facing heavier plates, increases the physical exertion of the staff, and the plate may become skewed during the manual pushing of the plate.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hydraulic shearing machine, comprising a shearing machine and a shearing table, wherein the shearing table is opened at the front end of the shearing machine, and a calibration device and a shearing device are arranged on the shearing machine.

[0008] The calibration device includes a bidirectional motor, a transmission member, a connecting rod, and a calibration assembly. The bidirectional motor is installed inside the shearing table, two groups of the transmission members are respectively connected to the output ends on both sides of the bidirectional motor, two connecting rods are fixedly connected to the top of the transmission member, and two groups of the calibration assemblies are respectively installed on the inner side of the connecting rod.

[0009] A further improvement is that limiting grooves are respectively provided on the left and right sides of the upper surface of the shearing table, the transmission member is installed inside the limiting groove, the connecting rod is slidably connected to the inside of the limiting groove, and the bidirectional motor is started to drive the screw in the transmission member to rotate, thereby driving the threaded sleeve on the screw and the connecting rod on its top to move relative to each other along the limiting groove, thereby driving the calibration component to move relative to each other, clamping the plate in the center of the shearing table to complete the calibration work, avoiding the plate from being skewed and affecting the shearing of the plate.

[0010] A further improvement is that the calibration assembly includes a connecting column, a mounting plate, and rollers. The connecting column is fixedly connected to the inner top of the connecting rod, and the mounting plate is fixedly connected to the other end of the connecting column. Four groups of rollers are equidistantly installed inside the mounting plate through a rotating axis. When the two mounting plates move relative to each other, the rollers contact both sides of the plate, reducing friction and making loading easier.

[0011] A further improvement is that an alarm unit is also provided inside the calibration component, and the alarm unit includes a spring bin, a sliding rod, a flexible spring, and an electric contact. The spring bin is opened inside the connecting column, and the sliding rod is slidably connected to the inside of the spring bin, and its outer end is connected to the mounting plate. The two ends of the flexible spring are respectively fixedly connected to the inner wall of the spring bin and one end of the sliding rod, and the two electric contacts are respectively installed on the inner wall of the spring bin and the inner end of the sliding rod. When the roller contacts one side of the plate, the mounting plate continues to move relatively, thereby pushing the sliding rod to slide toward the inside of the spring bin and squeezing the flexible spring until the two electric contacts are in contact, sending an electrical signal, thereby stopping the bidirectional motor from running, avoiding excessive clamping and causing the plate to be squeezed and deformed.

[0012] A further improvement is that the shearing device comprises a shearing unit and a fixing unit.

[0013] The shearing unit includes a hydraulic cylinder, a shearing knife, and an engaging shearing knife. Several of the hydraulic cylinders are equidistantly installed inside the shearing machine. The shearing knife is fixedly connected to the bottom of the hydraulic cylinder. A mounting groove is provided at the rear end of the shearing table. The engaging shearing knife is installed inside the mounting groove. The hydraulic cylinder is started to push the shearing knife downward, and the engaging shearing knife at the bottom cooperates to complete the shearing process of the plate.

[0014] A further improvement is that the fixing unit includes a fixing plate, an electric push rod, a pressure plate, and a rubber pad, the fixing plate is fixedly connected to the upper front end of the shearing machine, a number of the electric push rods are equidistantly installed on the bottom of the fixing plate, the pressure plate is fixedly connected to the bottom of the electric push rod, and the rubber pad is adhered to the bottom of the pressure plate. Before shearing, the electric push rod is started to push the pressure plate downward, thereby fixing the plate from the top to prevent the plate from warping up during shearing and affecting subsequent shearing. The provision of the rubber pad prevents the pressure plate from being pressed down excessively, scratching the surface of the plate, and affecting the neatness and beauty of the plate after shearing.

[0015] A further improvement is that a conveyor belt is installed at the front end of the shearing machine, and a control box is installed on the right side of the shearing machine. The conveyor belt, calibration device and shearing device are electrically connected to the control box. The conveyor belt is used to automatically convey the plates, which improves the transportation efficiency and saves the workers' physical strength. The operation of the device is controlled by the control box.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The hydraulic shearing machine starts the bidirectional motor to drive the transmission part to rotate, so that the connecting rod on the top moves relatively along the limiting slide, thereby driving the calibration component to move relatively, clamping the plate in the center of the shearing table to complete the calibration work, avoiding the plate from skewing and affecting the shearing of the plate.

[0018] 2. In this hydraulic shearing machine, when the roller contacts one side of the plate, the mounting plate continues to move relatively, thereby pushing the slide bar to slide toward the inside of the spring compartment and squeezing the flexible spring until the two electrical contacts touch and send out an electrical signal, thereby stopping the bidirectional motor from running, avoiding excessive clamping that causes the plate to be squeezed and deformed.

[0019] 3. Before shearing, the hydraulic shearing machine starts the electric push rod to push the pressure plate down, thereby fixing the plate from the top to prevent the plate from warping up during shearing and affecting subsequent shearing. The setting of the rubber pad prevents the pressure plate from being pressed down too much and scratching the surface of the plate, affecting the neatness and beauty of the plate after shearing.
