Description

Technical Field

[0001] This utility model relates to the field of hydraulic shears, and in particular to a guiding device for hydraulic shears. Background Technology

[0002] Hydraulic shears, as a common cutting tool, are widely used in many fields such as industrial production, construction, and metal processing. According to the driving method, hydraulic shears are mainly divided into manual hydraulic shears and electric hydraulic shears. Among them, manual hydraulic shears are popular in some small-scale work scenarios or work environments with high mobility requirements due to their advantages such as simple operation and no need for external power supply. The main body of a manual hydraulic shear typically consists of a hydraulic system, an operating handle, and a shearing blade assembly. Its working principle is that by manually pressing the operating handle, the piston in the hydraulic system moves, causing the hydraulic oil to generate pressure, which in turn pushes the piston rod to extend or retract. The piston rod drives the moving blade head to reciprocate, cooperating with the fixed blade head to complete the cutting operation. In the operation of a manual hydraulic shear, the guiding device plays a crucial role. It ensures that the moving blade head maintains a stable trajectory during reciprocating motion, ensuring precise alignment between the moving and fixed blade heads, thereby improving the cutting accuracy and efficiency, while preventing wear or damage to the blade head due to misalignment, and extending the service life of the blade.

[0003] However, existing manual hydraulic shear guide devices have certain drawbacks. In actual use, the friction between the moving cutter head and the guide device is relatively high. This not only requires greater force to drive the moving cutter head during operation, increasing the operator's workload and reducing work efficiency, but also accelerates the wear of both the moving cutter head and the guide device, increasing maintenance costs and shortening the overall lifespan of the equipment. This, to some extent, limits the performance and application range of manual hydraulic shears. Utility Model Content

[0004] The main objective of this invention is to provide a guiding device for hydraulic shears, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A guiding device for a hydraulic shear includes a guiding assembly, which is fixedly mounted on a manual hydraulic shear body. A movable cutter head is fixedly mounted on the piston rod of the manual hydraulic shear body. A drag-reducing connecting assembly is slidably mounted inside the guiding assembly and is simultaneously connected to the movable cutter head. The drag-reducing connecting assembly consists of mounting plates, connecting blocks, a first rotating roller, and a second rotating roller. There are two mounting plates arranged symmetrically. There are two connecting blocks, each fixedly mounted at one end of a different mounting plate. There are two first rotating rollers, both of which are rotatably mounted within the two mounting plates.

[0007] Preferably, the inner wall of the guide component is provided with a cutter head mounting groove, and a fixed cutter head is fixedly installed in the cutter head mounting groove by bolts. The inner wall of the guide component is also provided with a guide rail receiving groove, and the guide rail receiving groove is connected to the cutter head mounting groove.

[0008] Preferably, two first roller grooves are symmetrically formed on the inner wall of the guide rail groove, and a second roller groove is also formed on the inner wall of the guide rail groove.

[0009] Preferably, the manual hydraulic shear body is equipped with an operating handle, the movable cutter head is fixedly connected to the piston rod of the manual hydraulic shear body by bolts, the movable cutter head is slidably mounted in the receiving guide groove, and the movable cutter head is provided with a through hole.

[0010] Preferably, the two mounting plates on the drag-reducing connection assembly are fixed together by bolts, and the two mounting plates are slidably installed in the receiving guide groove. The mounting plates have two first arc-shaped grooves and one second arc-shaped groove, and the two connecting blocks are inserted into the through holes opened on the moving cutter head.

[0011] Preferably, the first rotating roller is rotatably mounted in a first arc-shaped groove opened on two mounting plates, and the first rotating roller is simultaneously rotatably mounted in a first roller groove. The second rotating roller is rotatably mounted in a second arc-shaped groove opened on two mounting plates, and the second rotating roller is simultaneously rotatably mounted in a second roller groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By incorporating a drag-reducing connection component within the guide assembly and connecting the moving cutter head to the guide assembly via this component, the moving resistance of the moving cutter head can be reduced. This reduces the force required for the operator to drive the moving cutter head, effectively alleviating labor intensity and improving work efficiency. Simultaneously, it reduces friction between the moving cutter head and the guide assembly, thereby reducing wear on both components, lowering equipment maintenance costs, extending the overall service life of the equipment, and broadening the performance and application range of the manual hydraulic shears.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-5As shown, a guiding device for a hydraulic shear includes a guiding assembly 2, which is fixedly mounted on a manual hydraulic shear body 1. A movable cutter head 4 is fixedly mounted on the piston rod of the manual hydraulic shear body 1. A drag-reducing connecting assembly 3 is slidably mounted inside the guiding assembly 2 and is simultaneously connected to the movable cutter head 4. The drag-reducing connecting assembly 3 consists of mounting clamps 10, connecting blocks 13, a first rotating roller 14, and a second rotating roller 15. There are two mounting clamps 10 arranged symmetrically, and two connecting blocks 13 are fixedly mounted on one end of each of the two mounting clamps 10. There are two first rotating rollers 14, and both the first rotating roller 14 and the second rotating roller 15 are rotatably mounted on... Inside the two mounting plates 10, the inner wall of the guide assembly 2 is provided with a cutter head mounting groove 5. A fixed cutter head 6 is fixedly installed in the cutter head mounting groove 5 by bolts. The inner wall of the guide assembly 2 is also provided with a guide rail receiving groove 7, which is connected to the cutter head mounting groove 5. Two first roller grooves 8 are symmetrically opened on the inner wall of the guide rail receiving groove 7, and a second roller groove 9 is also opened on the inner wall of the guide rail receiving groove 7. An operating handle 16 is installed on the manual hydraulic shear body 1. The movable cutter head 4 is fixedly connected to the piston rod of the manual hydraulic shear body 1 by bolts. The movable cutter head 4 is slidably installed in the guide rail receiving groove 7. The movable cutter head 4 is provided with a through hole. When installing the movable cutter head 4, the movable cutter head 4 is first sleeved on the two connecting blocks 13 on the drag reduction connecting assembly 3 through the through hole, and then the movable cutter head 4 is... The piston rod is bolted to the main body 1 of the manual hydraulic shear. During use, the operator holds the operating handle 16 and manually presses it to drive the hydraulic system within the main body 1, causing the piston to move. The hydraulic oil generates pressure, pushing the piston rod to extend or retract. The piston rod drives the movable cutter head 4 to reciprocate within the guide rail groove 7. As the movable cutter head 4 moves, the two mounting plates 10 of the drag-reducing connecting assembly 3 slide within the guide rail groove 7. The first rotating roller 14 on the mounting plate 10 rotates within the first arc groove 11 and the first roller groove 8, while the second rotating roller 15 rotates within the second arc groove 12 and the second roller groove 9. Ultimately, the movable cutter head 4 cooperates with the fixed cutter head 6, which is fixedly installed in the cutter head mounting groove 5, to complete the shearing operation on the object placed between the movable cutter head 4 and the fixed cutter head 6. During use, the movable cutter head 4 and the mounting plates 10 do not contact the guide assembly 2, thus avoiding friction between them.

[0022] Specifically, the two mounting plates 10 on the drag-reducing connection assembly 3 are fixed together by bolts, and the two mounting plates 10 are slidably installed in the guide rail groove 7. The mounting plates 10 have two first arc-shaped grooves 11 and one second arc-shaped groove 12. Both connecting blocks 13 are inserted into the through holes on the moving cutter head 4. The first rotating roller 14 is rotatably installed in the first arc-shaped groove 11 on the two mounting plates 10, and simultaneously rotatably installed in the first roller groove 8. The second rotating roller 15 is rotatably installed in the second arc-shaped groove 12 on the two mounting plates 10, and simultaneously rotatably installed in the second roller groove 9. In this hydraulic shear guiding device... Lubricating oil needs to be added to the contact areas between the first roller 14 and the first arc groove 11 and the first roller groove 8, and to the contact areas between the second roller 15 and the second arc groove 12 and the second roller groove 9. Adding lubricating oil to these areas can reduce the frictional resistance of the first roller 14 and the second roller 15 when they rotate, and reduce the wear between them and the corresponding grooves. At the same time, it can also make the mounting clamp 10 slide more smoothly in the guide rail groove 7, further reduce the moving resistance of the moving cutter head 4, reduce the force required for the operator to drive the moving cutter head 4, improve work efficiency, and reduce the wear of the moving cutter head 4 and the guide assembly 2, reduce equipment maintenance costs, and extend the overall service life of the equipment.

[0023] Ultimately, by setting a drag-reducing connection component 3 within the guide component 2 and connecting the moving cutter head 4 to the guide component 2 via the drag-reducing connection component 3, the moving resistance of the moving cutter head 4 can be reduced. This reduces the force required by the operator to drive the moving cutter head 4, effectively reducing labor intensity and improving work efficiency. At the same time, it reduces friction between the moving cutter head 4 and the guide component 2, thereby reducing the wear of both the moving cutter head 4 and the guide component 2, lowering equipment maintenance costs, extending the overall service life of the equipment, and broadening the performance and application range of the manual hydraulic shears.

[0024] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
