Description

Technical Field

[0001] The invention relates to the technical field of wire rope cutting, and in particular to a high-precision rust-proof wire rope cutting device. Background Art

[0002] Steel wire rope is a spiral steel wire bundle twisted together according to certain rules with steel wires that meet the requirements of mechanical properties and geometric dimensions. Steel wire rope is composed of steel wire, rope core and grease. Steel wire rope is first twisted into strands by multiple layers of steel wires, and then a certain number of strands are twisted into a spiral rope with the rope core as the center. In material handling machinery, it is used for lifting, traction, tensioning and bearing. Steel wire rope has high strength, light weight, stable operation, not easy to break suddenly, and reliable operation.

[0003] At present, most wire ropes are cut into flat ends by cutting. In this way, more margin needs to be left when the ends are tied and fixed after cutting, otherwise it is not easy to fix them firmly. Summary of the invention

[0004] In order to solve the deficiencies in the prior art, the present invention provides a high-precision rust-proof steel wire rope cutting device.

[0005] The technical solution of the present invention is:

[0006] The present invention provides a high-precision rust-proof wire rope cutting device, comprising a rotating drum, which is rotatably installed on a bracket, two shafts are symmetrically arranged inside the rotating drum along the central axis, both ends of the shafts are installed on the inner side of a slide rail radially arranged on the inner wall of the rotating drum through a first slider, the first slider and the inner wall of the rotating drum are connected through a first electric push rod, two sliding sleeves are symmetrically arranged on the shaft along the center, the inner end of the sliding sleeve is provided with a cutting blade, the rotation center line of the cutting blade has an angle α with the center line of the shaft, the bottom of the cutting blade is biased toward the center side of the shaft, and the sliding sleeve is connected to the corresponding first slider through a second electric push rod.

[0007] Furthermore, clamping components are arranged inside the drum and outside the cutting blades.

[0008] Furthermore, a rolling structure is provided inside the clamping assembly.

[0009] Furthermore, the clamping assembly includes two clamping sleeves symmetrically arranged along the central axis of the rotating drum, the outer ends of the clamping sleeves are fixedly connected to the second slider outside the slide rail, and the second slider is connected to the rotating drum through a third electric push rod.

[0010] Furthermore, the rolling structure includes a plurality of rollers evenly distributed inside the clamping sleeve.

[0011] Furthermore, the sliding sleeve has a mounting sleeve whose central axis forms an angle α with the central axis of the shaft, and the cutting blade is rotatably mounted on the outer ring of the mounting sleeve.

[0012] Furthermore, a fixed sleeve is fixedly mounted on the bracket and sleeved on the outside of the rotating drum. A gear ring is arranged on the outside of the rotating drum. The rotating drum can be driven to rotate through the gear ring by an added driving device.

[0013] The beneficial effects achieved by the present invention are:

[0014] The cut end of the wire rope after cutting by the present invention has a certain taper. The end of the wire rope with a taper can be closer to the end position when fixed and bundled, which cannot be achieved by the traditional cutting method. The cross-section after cutting by the traditional cutting method is flat. Due to the shrinkage of the steel wire, the traditional end bundling often has to leave more margins, so the cutting length is not accurate enough. The present device can cut the length more accurately, and the end of the wire rope after cutting does not require more margins for bundling. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] To facilitate those skilled in the art to understand the present invention, specific implementations of the present invention are described below with reference to the accompanying drawings.

[0019] like Figures 1 to 3 As shown, the present invention provides a high-precision rust-proof steel wire rope cutting device, comprising a rotating drum 1, which is rotatably mounted on a bracket 2, two shafts 3 are symmetrically arranged along the central axis inside the rotating drum 1, both ends of the shaft 3 are mounted on the inner side of a slide rail 5 radially arranged on the inner wall of the rotating drum through a first slider 4, the first slider 4 and the inner wall of the rotating drum 1 are connected through a first electric push rod 6, two sliding sleeves 7 are symmetrically mounted along the center of the shaft 3, the inner end of the sliding sleeve 7 is mounted on the rotating drum with a cutting blade 8, the rotation center line of the cutting blade 8 has an angle α with the center line of the shaft 3, the bottom of the cutting blade is biased toward the center side of the shaft, the sliding sleeve is connected to the corresponding first slider through a second electric push rod 9, clamping assemblies are arranged on the outer sides of the cutting blades inside the rotating drum, a rolling structure is arranged inside the clamping assembly, and the rust-proof steel wire rope passing through the center line of the rotating drum is clamped by the clamping assembly.

[0020] like Figure 2As shown, the clamping assembly includes two clamping sleeves 10 symmetrically arranged along the central axis of the rotating drum. The outer end of the clamping sleeve 10 is fixedly connected to a second slider 11 outside the slide rail 5. The second slider 11 is connected to the rotating drum through a third electric push rod 12. A plurality of rollers 13 are evenly distributed inside the clamping sleeve 10. When the two clamping sleeves 10 are close to each other, the outer surface of the rust-proof steel wire rope 17 is evenly compressed by the plurality of rollers 13.

[0021] The sliding sleeve 7 has a mounting sleeve 14 whose central axis forms an angle α with the central axis of the shaft. The cutting blade is rotatably mounted on the outer ring of the mounting sleeve. This design can make the installation of the cutting blade more convenient.

[0022] A fixing sleeve 15 is fixedly mounted on the bracket 2 and sleeved on the outer side of the drum. A gear ring 16 is arranged on the outer side of the drum. The drum can be driven to rotate through the gear ring by an added driving device.

[0023] Usage process: When in use, pass the rust-proof steel wire rope through the center of the drum, clamp the steel wire rope on both sides of the cutting blade through two clamping assemblies, then the drum rotates slowly under the drive of the driving device, and the first electric push rod slowly extends, and the cutting blade cuts the steel wire rope while rotating around it. At the same time, the second electric push rod also slowly extends to ensure that the cutting blade moves in the direction of its own blade. After cutting, the cut end of the steel wire rope has a certain taper (such as Figure 3 As shown in the figure, the end of the tapered wire rope can be closer to the end position when fixed and tied, which is impossible to achieve with the traditional cutting method. The cross section after cutting with the traditional cutting method is flat. Due to the shrinkage of the steel wire, the traditional end bundling often leaves more margin, resulting in the cutting length not being accurate enough. The device can cut the length more accurately, and no more margin is needed for bundling the end of the wire rope after cutting.

[0024] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
