Description

Technical Field

[0001] This utility model relates to a tool assembly for cutting large-diameter steel wire ropes, mainly used for spark-free cutting of steel wire ropes on engineering sites. Background Technology

[0002] Currently, due to increasingly stringent environmental protection requirements, there is an urgent need on construction sites for a large-diameter wire rope cutting machine to replace the existing flame cutting process. Small-diameter wire ropes can be cut directly with wire cutters or pliers; however, large-diameter wire ropes have a large diameter and high strength and toughness, making them impossible to cut with ordinary-sized scissors or pliers. Even large double-edged tools like scissors or pliers are ineffective due to the large diameter of the wire rope. Short-bladed scissors exert greater lateral force, causing the wire rope to slip easily, requiring multiple cuts for even a few successful cuts. Long-bladed scissors exert less lateral force, making the wire rope less prone to slippage, but their torsional resistance is reduced, making the blades more susceptible to twisting and bending, thus causing damage. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a tool assembly for cutting large-diameter steel wire ropes, which adopts a lightweight and easy-to-replace design for steel wire rope cutting.

[0004] This utility model is achieved through the following technical solution: a tool assembly for cutting large-diameter steel wire rope, comprising a moving blade, a stationary blade, and a hydraulic cylinder, wherein the moving blade is engaged with the stationary blade, the cylinder assembly of the hydraulic cylinder is connected to the stationary blade, and the piston rod of the hydraulic cylinder is connected to the moving blade.

[0005] The stationary blade adopts a U-shaped structure and has two cutting edges inside. The stationary blade is a double-edged structure with an arc-shaped obtuse angle.

[0006] The moving blade is a single-edged structure with an arc-shaped acute angle.

[0007] The stationary blade is provided with a through hole, which is connected to the hydraulic cylinder barrel assembly.

[0008] The beneficial effects of this invention are: the arc-shaped cutting edge prevents the wire rope from slipping, resulting in a high success rate in cutting the rope; the three parallel cutting edges prevent the tool from twisting, extending its lifespan; and the combination of acute and obtuse angle cutting edges effectively reduces operating costs.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model; the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In addition, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0015] like Figure 1 and Figure 2 The tool assembly shown includes a moving blade 1, a stationary blade 2, and a hydraulic cylinder 3 for cutting large-diameter steel wire ropes. The moving blade 1 is engaged with the stationary blade 2, the cylinder assembly of the hydraulic cylinder 3 is connected to the stationary blade 2, and the piston rod of the hydraulic cylinder 3 is connected to the moving blade 1.

[0016] The stationary blade 2 adopts a U-shaped structure and has two cutting edges inside. The stationary blade 2 is an arc-shaped obtuse-angled double-edged structure.

[0017] The moving blade 1 is a single-edged structure with an arc-shaped acute angle.

[0018] The stationary blade 2 is provided with a through hole 4, which is connected to the cylinder assembly of the hydraulic cylinder 3.

[0019] The moving blade 1 applies a compressive force to the wire rope, pushing it towards the edge of the stationary blade 2; the stationary blade 2 has two stationary blade edges 5; the three blades work together to cut the wire rope.

[0020] Moving blade 1 is a single-edged structure with an acute arc angle, which is lower in cost and features a lightweight and easy-to-replace design. Stationary blade 2 is a double-edged structure with an obtuse arc angle, which is more expensive but features a robust design with a long service life. Hydraulic cylinder 3 serves as the power source, and both moving and stationary blades are made of cold-work die steel, with the cutting tools undergoing vacuum quenching treatment.

[0021] The hydraulic cylinder 3 is driven to apply a compressive force to the wire rope, forcing it to the stationary blade edge 5. Pressure is continued to be applied to complete the shearing of the wire rope.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
