Description

Technical Field

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

[0002] Shearing machines are used to shear metal plates. The shearing machine blade relies on the shearing machine tool holder to shear the metal plate up and down through the mechanical hydraulic system to complete the process of shearing the plate. The blades used in shearing machines are generally required to have strong comprehensive performance. If the performance is not good, it is difficult to shear the plate, and it is easy to deform and break the blade during the shearing process. For shearing machine blades, the main factors affecting the performance of the blade are its processing and manufacturing process, including material selection, forging process, heat treatment process, etc. Different processing processes will have a greater impact on the performance of the blade.

[0003] Before the plate is formally sheared, it needs to be adjusted and corrected to ensure the accuracy of its position under the shear knife. Generally, the operator places it directly under the shear knife and makes adjustments, and finally relies on the positioning assembly to complete the positioning and clamping. Since it is corrected and adjusted under the shear knife, it is highly dangerous. In order to cope with the above technical problems, it is necessary to improve the above hydraulic cylinder shearing machine, so a hydraulic shearing machine with a correction structure is proposed.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely 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, rather than all of the embodiments.

[0021] Reference Figure 1-3 A hydraulic shearing machine with a correction structure comprises a fixed frame 1, a shearing knife 3 is provided on the fixed frame 1 through a hydraulic cylinder 2, a movable seat 4 is provided on the fixed frame 1, a plurality of rotating grooves 6 are provided on the upper end surface of the movable seat 4, a transmission cavity 12 is provided inside the movable seat 4, a movable screw 13 is provided in the rotating groove 6 through a supporting plate 11, a driving gear 14 is provided in the transmission cavity 12, the movable screw 13 is connected to the driving gear 14 through a rotating mechanism, a movable plate 7 is threadedly installed on the movable screw 13, an adjusting plate 8 is provided on the movable plate 7 through an adjusting mechanism, a movable screw 16 is provided on the fixed frame 1 through a motor, a movable block 17 is threadedly installed on the movable screw 16, a transmission shaft 18 connected to the driving gear 14 is rotatably provided on the movable block 17, a rack 20 is installed on the fixed frame 1, and the transmission shaft 18 is connected to the rack 20 through a transmission mechanism.

[0022] The rotating mechanism includes a rotating gear 15 mounted on the movable screw 13, and the driving gear 14 is meshed with the rotating gear 15. As shown in the figure, the driving gear 14 and the rotating gear 15 are both bevel gears, which are vertically meshed with each other. For details, please refer to the attached Figure 3 shown.

[0023] The adjustment mechanism includes an adjustment screw 9 threadedly mounted on the movable plate 7, on which an adjustment plate 8 is rotatably mounted. As shown in the figure, a rotating block is also provided on the adjustment screw 9, by means of which the rotation of the adjustment screw 9 can be achieved.

[0024] The transmission mechanism includes a transmission gear 19 installed on the transmission shaft 18, and the transmission gear 19 is meshed with a rack 20. When the transmission gear 19 follows the transmission shaft 18 and the moving block 17 to move, the transmission gear 19 can rotate under the action of the rack 20, thereby realizing the rotation of the driving gear 14.

[0025] Limit rods 10 are provided on the fixed frame 1, the rotating groove 6 and the adjustment plate 8. The three limit rods 10 slide through the moving block 17 and the movable plate 7 respectively. The function of the above-mentioned limit rods 10 is to limit, so as to prevent the adjustment plate 8 from rotating with the adjustment screw 9, to prevent the movable plate 7 from rotating with the movable screw 13, and to prevent the moving block 17 from rotating with the moving screw 16.

[0026] A protective pad is provided on the surface of the adjustment plate 8, and the protective pad is made of rubber material. The rubber protective pad can prevent the adjustment plate 8 from causing damage to the vertical outer wall of the plate.

[0027] When the utility model is used, in the initial state, the movable seat 4 is away from the shearing knife 3, and the spacing between the multiple movable plates 7 and the adjustment plate 8 is the largest. At this time, the plate is placed on the movable seat 4, and then the motor is started to drive the movable screw 16 to rotate. When the movable screw 16 rotates, the movable block 17 drives the transmission shaft 18 and other components to move, so that the movable seat 4 drives the plate to approach the shearing knife 3. In this process, the transmission gear 19 rotates under the action of the rack 20, thereby driving the transmission shaft 18 to rotate, and the transmission shaft 18 drives the active gear 14 to rotate. The active gear 14 cooperates with the rotating gear 15 to drive the movable screw 13 to rotate. When the movable screw 13 rotates, the movable plate 7 drives the adjustment plate 8 to move synchronously, and finally realizes the extrusion and fixing operation of the vertical outer wall of the plate. When it is directly below the shearing knife 3, the plate is in the most stable clamping state. At this time, the hydraulic cylinder 2 descends to drive the shearing knife 3 to realize the shearing operation of the plate, and the processing groove 5 is set to deal with the shearing knife 3.

[0028] In this solution, the four movable plates 7 and the adjustment plate 8 can clamp a square plate. Some plates are rectangular. In this case, two of the adjustment plates 8 need to be adjusted to create a distance between them and the movable plate 7. The adjustment screw 9 can be adjusted and rotated. After adjustment, the memory is formed.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
