Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic shears, in particular to an inlaid alloy blade hydraulic shear. Background Art

[0002] Hydraulic shears are one of the products of rescue tools. Hydraulic shears are like a big mouth for biting things. They can bite through metal and other materials used in vehicles. They have high strength, great power, small size, light weight and excellent quality. In modern industrial production, especially in the metal processing and composite material processing industries, efficient cutting tools are the key to ensuring product quality and production efficiency. Traditional cutting equipment often has problems such as low cutting accuracy, inconvenient blade replacement and short service life. These problems are more prominent especially when facing the cutting operation of high-strength and high-hardness materials.

[0003] Existing hydraulic shears usually use a fixed blade structure. Once the blade is worn or damaged, the entire cutting assembly needs to be disassembled and replaced, which is not only time-consuming and labor-intensive, but may also affect production progress. In addition, due to the limitations of the blade fixing method, it is difficult to achieve rapid replacement and adjustment of the blade while ensuring cutting accuracy, which to a certain extent limits its application in the field of high-precision cutting.

[0032] To better understand the purpose, structure, and function of the present utility model, the inlaid alloy blade hydraulic shear of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] As Figures 1-7 shown, the embodiments of the present utility model provide an inlaid alloy blade hydraulic shear, including a support member 100 for hand-held support, and a cutting blade 200 installed on one side of the support member 100 for cutting an article. The cutting blade 200 is fitted and installed inside the support member 100, and a hydraulic working part 300 for driving the support member 100 to rotate and cut is fixedly installed on one side of the support member 100.

[0034] The support member 100 includes a fixing member 120 fixedly installed on one side of the hydraulic working part 300 for support, and a rotating frame 130 movably installed on one side of the fixing member 120 for driving the cutting blade 200 to rotate and cut. An expansion member 110 for driving the rotating frame 130 installed on one side to rotate is movably installed inside the fixing member 120, and the other end of the expansion member 110 is connected to the hydraulic working part 300.

[0035] When a cutting operation needs to be performed using a hydraulic shear, the hydraulic working part 300 can drive the telescopic member 110 to move, thereby driving the rotatable frame 130 movably installed on one side to rotate, driving the cutting blade 200 installed in a fitting manner inside to open and close for cutting. The cutting blade 200 fitted and installed inside the rotatable frame 130 can be replaced to ensure the normal use of the cutting blade 200 and avoid poor cutting effects caused by wear of the cutting blade 200.

[0036] Positioning rods 121 for installing the rotatable frame 130 are fixedly installed on both sides of the fixing member 120. The ends of the positioning rods 121 are movably installed on one side of the rotatable frame 130 through mounting shafts. The inner side of the rotatable frame 130 is connected to the telescopic member 110 through a connecting shaft. When the rotatable frame 130 rotates for cutting, the fixedly installed positioning rods 121 can support it. The hydraulic working part 300 drives the telescopic member 110 to retract inward, thereby driving the cutting blade 200 to rotate and cut, ensuring the stability of the rotatable frame 130 and having a better supporting effect.

[0037] A telescopic rod 111 for driving the telescopic member 110 to move telescopically is fixedly installed on one side of the telescopic member 110. The telescopic rod 111 is fixedly connected to the output end of the hydraulic working part 300. The telescopic member 110 is driven to move through the telescopic rod 111 and the hydraulic working part 300, thereby driving the rotatable frame 130 to open and close, enabling the rotatable frame 130 to open and close stably.

[0038] A shaft body 131 for installing the telescopic member 110 and the positioning rod 121 is arranged at one end of the rotatable frame 130. An installation groove 132 for installing the cutting blade 200 is formed inside the rotatable frame 130. A clamping member 500 for clamping and fixing the cutting blade 200 is movably installed inside the installation groove 132.

[0039] The clamping member 500 includes a movable frame 510 fitted and installed inside the installation groove 132 for fixing the cutting blade 200 and a push plate 520 fixedly installed on one side of the movable frame 510 for fixing the blade. An anti-slip gasket can be coated outside the push plate 520 to prevent sliding during the blade clamping process. A telescopic screw rod 540 for pushing the movable frame 510 to move and clamp is rotatably installed on one side of the movable frame 510 through a bearing.

[0040] When fixing the cutting blade 200, the cutting blade 200 can be inserted into the installation groove 132. Then, the telescopic screw rod 540 is rotated to push the movable frame 510 to move inward, thereby pushing the push plate 520 to clamp and fix inward, ensuring the stable installation of the cutting blade 200. At the same time, it is convenient to replace the cutting blade 200, and the fixing is simple.

[0041] The interior of the installation groove 132 is provided with a threaded hole 134 for driving the moving frame 510 to move. The telescopic screw rod 540 is threadedly installed inside the threaded hole 134. The outer end of the telescopic screw rod 540 is connected to a rotating handle. The threaded hole 134 can install the telescopic screw rod 540 and at the same time extend to the outside of the rotating frame 130 for installation. The rotating handle can adjust the telescopic screw rod 540, which is convenient for operation.

[0042] A limiting rod 133 for moving the moving frame 510 is fixedly installed inside the installation groove 132. A limiting hole 530 for limiting and fixing the moving frame 510 is penetrated through the upper end of the moving frame 510. The limiting rod 133 is movably installed inside the limiting hole 530. During the movement of the clamping member 500, the limiting rod 133 and the limiting hole 530 are matched for limiting operation to prevent the moving frame 510 from rotating and offsetting during movement.

[0043] A cleaning part 600 for cleaning the side of the cutting blade 200 is fitted and installed at the edge of the installation groove 132. The cleaning part 600 can be made of materials such as a brush or a sponge. The cleaning part 600 can be arranged in a U shape and is fixedly installed on the outer edge of the installation groove 132. During the installation of the cutting blade 200, the externally installed cleaning part 600 can wipe the installed part when the cutting blade 200 is inserted into the installation groove 132, removing the dust and impurities adhered to its upper end, preventing dust particles from entering the installation groove 132, and avoiding the existence of particulate impurities on the contact surface between the push plate 520 and the cutting blade 200 during the fixing of the cutting blade 200, which affects the fixing of the cutting blade 200.

[0044] A magnet part 610 for installing and adsorbing the cleaning part 600 is arranged at the upper end of the cleaning part 600. The magnet part 610 is adsorbed and installed at the notch opened at the edge of the installation groove 132 and can be firmly installed by screws. It can be temporarily adsorbed and fixed by the magnet part 610, which is convenient for installing and positioning the cleaning part 600.

[0045] A lifting frame 400 for assisting the user in holding work is movably installed at the upper end of the support member 100. The lifting frame 400 is movably installed on both sides of the collar arranged at the upper end of the support member 100 through bearings. When the user operates, the lifting frame 400 can assist the user, which is convenient for holding and fixing.

[0046] Working principle of the inlaid alloy blade hydraulic shear: When it is necessary to use the hydraulic shear for cutting operations, the hydraulic working part 300 can drive the telescopic part 110 to move, thereby driving the rotatable frame 130 movably installed on one side to rotate, driving the cutting blade 200 installed inside in a fitted manner to open and close for cutting. The cutting blade 200 fitted and installed inside the rotatable frame 130 can be replaced to ensure the normal use of the cutting blade 200 and avoid poor cutting effects caused by wear of the cutting blade 200. When fixing the cutting blade 200, the cutting blade 200 can be inserted into the installation groove 132, and then the telescopic screw rod 540 is rotated to push the movable frame 510 to move inward, thereby pushing the push plate 520 to clamp and fix inward, ensuring the stable installation of the cutting blade 200 and at the same time facilitating the replacement of the cutting blade 200, with simple fixation.
