Technical Field
[0001] The utility model relates to the technical field of hydraulic presses, and particularly relates to a positioning mechanism for the operation of a hydraulic press. Background Art
[0002] A hydraulic press is a mechanical device that uses hydraulic transmission and hydraulic control technologies to perform operations such as workpiece forming, processing, and stamping. Hydraulic presses are widely used in fields such as metal processing, plastic molding, and rubber product production. Hydraulic presses include hydraulic punching presses, hydraulic presses, hydraulic bending machines, and hydraulic shearing machines, etc. Among them, the hydraulic shearing machine is mainly used for shearing metal articles. The metal article to be sheared is placed on the workbench of the hydraulic shearing machine. The pressing hydraulic cylinder drives the pressing rod to rotate around the rotating shaft, so that the pressing rod presses obliquely on the metal article. Then the shearing hydraulic cylinder drives the cutter on the tool rest to rotate downward to realize the shearing of the metal article. The pressing rod and the pressing hydraulic cylinder installed on the pressing rod are the positioning mechanism for the operation of the hydraulic press. After positioning the metal article, it is sheared, improving the safety and stability during the shearing process.
[0003] When the hydraulic shearing machine of the hydraulic press is in use, the pressing hydraulic cylinder drives the pressing rod to rotate, so that the pressing rod presses obliquely on the metal article to realize the positioning of the metal article and then shear it. When positioning a cylindrical metal article, the cylindrical metal article is obliquely squeezed by the pressing rod, and the cylindrical metal article is likely to roll on the workbench, and the positioning of the cylindrical metal article is not stable and reliable enough. Therefore, this application provides a positioning mechanism for the operation of a hydraulic press to meet the requirements. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a positioning mechanism for the operation of a hydraulic press to solve the technical problem that when positioning a cylindrical metal article, the cylindrical metal article is obliquely squeezed by the pressing rod, and the cylindrical metal article is likely to roll on the workbench, and the positioning of the cylindrical metal article is not stable and reliable enough.
[0005] To solve the above technical problems, the present utility model provides the following technical solution: A positioning mechanism for a hydraulic press includes a workbench. A bracket is fixed on the workbench, and a driving member is fixed on the bracket. The telescopic end of the driving member movably penetrates through the bracket and is fixed with a long bar. Two vertical bars are fixed to the bottom of the long bar, and connecting seats are fixed to the bottoms of the two vertical bars. The two connecting seats are respectively slidably connected to the two sides of the inner wall of the bracket. A pressing plate is arranged between the two connecting seats. Rope grooves are formed on both sides of the pressing plate, and steel wires are arranged in the rope grooves. A square box and a positioning column are respectively fixed to the top of the pressing plate. A slider is slidably connected to the inner wall of the square box. The bottom of the slider is fixed to one end of the steel wire, and the other end of the steel wire is fixed with a round sleeve. The round sleeve is rotatably connected in the connecting seat. A spring and a columnar block are respectively fixed to the bottom of the slider. The bottom of the spring is fixed to the top of the pressing plate. The columnar block is located inside the spring. A positioning sleeve is fixed to the bottom of the long bar, and the inner wall of the positioning sleeve is slidably connected to the circumferential surface of the positioning column.
[0006] Preferably, a guiding component is arranged on the side of the connecting seat. The guiding component includes a guiding block fixed to the side of the connecting seat, and a guiding groove is formed on the side of the inner wall of the bracket. The guiding block is slidably connected in the guiding groove.
[0007] Preferably, the guiding block is in an isosceles trapezoid shape, and the shape of the guiding groove is adapted to the shape of the guiding block.
[0008] Preferably, notches are arranged on both sides of the pressing plate.
[0009] Preferably, the width of the long bar is less than the height of the long bar.
[0010] Preferably, the central axis of the vertical bar is perpendicular to the central axis of the long bar.
[0011] Preferably, the driving member is a hydraulic cylinder.
[0012] Preferably, a curved surface is arranged on the inner wall of the rope groove.
[0013] Preferably, a plurality of pressing blocks are fixed to the bottom of the pressing plate, and the pressing blocks are located below the steel wires.
[0014] Preferably, the pressing blocks are in a frustum of a pyramid shape.
[0015] Compared with the prior art, the present utility model has at least the following beneficial effects: In the above solution, through the setting of the driving member, the steel wire and the pressing plate, after placing a cylindrical metal object on the workbench, the driving member is started to make the steel wire and the pressing plate move downward. When the pressing plate is flat on the cylindrical object, the steel wire continues to move downward and wraps around both sides of the cylindrical metal object. Through the cooperation of the pressing plate and the steel wire, the cylindrical metal object is prevented from moving on the workbench, thereby realizing stable and reliable positioning of the cylindrical metal object.
[0016] Through the setting of the pressing block, when the pressing plate presses on the cylindrical metal object, the frustum-shaped pressing block contacts the cylindrical metal object, and the frustum-shaped pressing block increases the friction between the pressing plate and the cylindrical metal object, thereby further improving the positioning stability of the cylindrical metal object.

[0028] Such as Figures 1-4As shown in the figure, an embodiment of the utility model provides a positioning mechanism for a hydraulic press, including a workbench 1, a bracket 2 is fixed on the workbench 1, a driving member 3 is fixed on the bracket 2, the telescopic end of the driving member 3 movably penetrates through the bracket 2 and is fixed with a long bar 4, two vertical bars 5 are fixed at the bottom of the long bar 4, connection seats 6 are fixed at the bottoms of the two vertical bars 5, and the two connection seats 6 are respectively slidably connected to the two sides of the inner wall of the bracket 2. A pressing plate 7 is arranged between the two connection seats 6, and the two connection seats 6 are respectively located on the left side and the rear side of the pressing plate 7. Rope grooves 8 are formed on both sides of the pressing plate 7, steel wire ropes 16 are arranged in the rope grooves 8, a square box 11 and a positioning column 17 are respectively fixed at the top of the pressing plate 7, a slider 12 is slidably connected to the inner wall of the square box 11, the bottom of the slider 12 is fixedly connected to one end of the steel wire rope 16, the other end of the steel wire rope 16 is fixed with a round sleeve 10, the round sleeve 10 is rotatably connected in the connection seat 6, a rotating shaft is fixed on the inner wall of the connection seat 6, and the round sleeve 10 is movably sleeved on the rotating shaft, so as to realize the rotational connection between the round sleeve 10 and the connection seat 6. One end of the steel wire rope 16 is connected to the round sleeve 10, and the other end passes through the rope groove 8 and is connected to the bottom of the slider 12. When the steel wire rope 16 moves downward, the pressing plate 7 can be driven to move downward through the rope groove 8. Springs 13 and columnar blocks 14 are respectively fixed at the bottom of the slider 12, the bottom of the spring 13 is fixedly connected to the top of the pressing plate 7, the columnar block 14 is located inside the spring 13, a positioning sleeve 18 is fixed at the bottom of the long bar 4, and the inner wall of the positioning sleeve 18 is slidably connected to the circumferential surface of the positioning column 17. When the pressing plate 7 moves downward, the positioning column 17 is driven to move downward along the inner wall of the positioning sleeve 18. The positioning of the pressing plate 7 is realized through the cooperation between the positioning column 17 and the positioning sleeve 18, preventing the pressing plate 7 from rotating in the front-back direction when the cutter shears the cylindrical metal article, and ensuring the stable positioning state of the pressing plate 7 for the cylindrical metal article.
[0029] As Figure 2 shown, in this embodiment, a guiding assembly 9 is arranged on the side surface of the connection seat 6. The guiding assembly 9 includes a guiding block 91 fixed on the side surface of the connection seat 6, a guiding groove 92 is formed on the side surface of the inner wall of the bracket 2, and the guiding block 91 is slidably connected in the guiding groove 92. When the connection seat 6 moves, the guiding block 91 is driven to move along the inner wall of the guiding groove 92. The guiding block 91 plays a guiding role in the movement of the connection seat 6, making the vertical movement of the connection seat 6 smoother.
[0030] As Figure 3 shown, in this embodiment, the guiding block 91 is in an isosceles trapezoid shape, and the shape of the guiding groove 92 is adapted to the shape of the guiding block 91. The guiding ability of the guiding groove 92 for the guiding block 91 is increased through the isosceles trapezoid shape, thereby improving the guiding ability for the connection seat 6.
[0031] As Figure 2As shown, in this embodiment, notches are provided on both sides of the pressing plate 7. When the steel wire rope 16 bends on the side of the pressing plate 7, a section of the steel wire rope 16 will not come into contact with the cylindrical metal object, resulting in a positioning dead angle. Through the design of the notches, when the steel wire rope 16 wraps around both sides of the cylindrical metal object, it directly bends at the notches, reducing the positioning dead angle when the steel wire rope 16 bends on the side of the pressing plate 7, thereby improving the positioning stability of the cylindrical metal object.
[0032] As Figure 4 shown, in this embodiment, the width of the long bar 4 is less than the height of the long bar 4, effectively preventing the long bar 4 from bending and deforming under force.
[0033] As Figure 2 shown, in this embodiment, the central axis of the vertical bar 5 is perpendicular to the central axis of the long bar 4.
[0034] As Figure 1 shown, in this embodiment, the driving member 3 is a hydraulic cylinder. By means of hydraulic drive, the pressing plate 7 and the steel wire rope 16 achieve stable positioning of the cylindrical metal object, and the pressure for pressing down the cylindrical metal object is increased, thereby ensuring the positioning stability of the cylindrical metal object.
[0035] As Figure 2 shown, in this embodiment, the inner wall of the rope groove 8 is provided with a curved surface, which corresponds to the bending portion of the steel wire rope 16. The curved surface enables the steel wire rope 16 to move more smoothly in the rope groove 8.
[0036] As Figure 2 shown, in this embodiment, a plurality of pressing blocks 15 are fixed to the bottom of the pressing plate 7. The pressing blocks 15 are located below the steel wire rope 16. When the pressing plate 7 presses on the cylindrical metal object, the pressing blocks 15 come into contact with the cylindrical metal object, and the friction force between the pressing plate 7 and the cylindrical metal object is increased by using the pressing blocks 15, thereby improving the positioning stability of the cylindrical metal object.
[0037] As Figure 2 and Figure 4 shown, in this embodiment, the pressing block 15 is in the shape of a frustum of a pyramid. The frustum of a pyramid shape can effectively prevent the pressing block 15 from deforming itself, thereby improving the service life of the pressing block 15.
[0038] Working principle: After placing the cylindrical metal object on the workbench 1, start the driving member 3. The piston rod of the driving member 3 extends to drive the long bar 4 to move downward. The long bar 4 drives the two connecting seats 6 to move downward along the inner side wall of the bracket 2 through the vertical rod 5. The connecting seat 6 drives the guiding block 91 to move downward along the inner wall of the guiding groove 92. The guiding block 91 guides the movement of the connecting seat 6, making the vertical movement of the connecting seat 6 smoother. The connecting seat 6 drives the steel wire rope 16 to move downward through the round sleeve 10. The steel wire rope 16 drives the pressing plate 7 to move downward. When the pressing plate 7 is flatly pressed on the cylindrical object, the pressing plate 7 stops moving downward. The connecting seat 6 continues to drive the steel wire rope 16 to move downward. At this time, the steel wire rope 16 drives the slider 12 to move downward along the inner wall of the square box 11 and compress the spring 13. The spring 13 is in a compressed state. At the same time, the slider 12 drives the columnar block 14 to continue moving downward until the columnar block 14 fits against the top of the pressing plate 7. After the fit, the driving member 3 stops driving the connecting seat 6 to move downward. At this time, the two steel wire ropes 16 are looped on both sides of the cylindrical metal object. Through the cooperation of the pressing plate 7 and the steel wire rope 16, the cylindrical metal object is prevented from moving on the workbench 1, thereby realizing the stable and reliable positioning of the cylindrical metal object. After positioning the cylindrical metal object, the shearing hydraulic cylinder drives the cutter to rotate downward to shear the cylindrical metal object. After the shearing is completed, the piston rod of the driving member 3 shortens to drive the connecting seat 6 to move upward through the long bar 4 and the vertical rod 5. The connecting seat 6 no longer pulls the steel wire rope 16. At this time, the slider 12 drives the top of the steel wire rope 16 to move upward under the elastic force of the spring 13, making the steel wire ropes 16 looped on both sides of the cylindrical metal object gradually change to a horizontal state. Then the connecting seat 6 continues to move upward to drive the steel wire rope 16 to drive the pressing plate 7 to move upward to separate the pressing plate 7 from the cylindrical metal object. After separation, the cylindrical metal object is taken off the workbench 1 or the cylindrical metal object is moved to perform shearing processing again. When the pressing plate 7 moves downward, it drives the positioning column 17 to move downward along the inner wall of the positioning sleeve 18. Through the cooperation of the positioning column 17 and the positioning sleeve 18, the pressing plate 7 is prevented from rotating in the front-back direction when the cutter shears the cylindrical metal object, ensuring the flat and stable positioning state of the pressing plate 7 on the cylindrical metal object.

In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model even without the description of these details.
[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
