Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a method for machining rope grooves for winch drums. Background Technology

[0002] To effectively limit the position of the winch wire rope, a rope groove is usually made on the drum. Currently, the common method for machining the rope groove is to use a profile cutting tool on a horizontal lathe. However, due to structural limitations, horizontal lathes cannot machine large drums, such as drums with a diameter of 1.3 meters and a length of 0.8 meters. Especially when machining a large rope groove on the drum, the tool needs to cut a large groove in one go, which puts a lot of force on the tool and can easily damage the tool during the machining process.

[0003] In the past, large vertical lathes were mainly used to machine the beveling of cylindrical end faces and inner and outer surfaces. In order to meet production needs and maximize the processing capacity of machine tools, it is necessary to invent a method to solve the problem of the limitations of machine tools when machining the rope grooves of large rollers and to effectively utilize large vertical lathes. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides a method for machining rope grooves for winch drums. By clamping a large drum onto a large vertical lathe, the rope grooves of the drum can be machined using the large vertical lathe by setting the program of the large vertical lathe.

[0005] To achieve the above objectives, the technical solution of the present invention is: a method for processing rope grooves for winch drums, comprising the following steps:

[0006] S1. Anti-deformation setting for the roller: Two or more reinforcing frames are installed inside the roller to enhance the structural strength of the roller.

[0007] S2. Clamp the roller onto the chuck of the vertical lathe; clamp the cutting tool and set the tool.

[0008] S3. Start the machine to begin processing. The roller rotates around the axis, and the cutter moves in a straight line from top to bottom. The movement of the cutter from the upper surface of the roller to the lower surface of the roller is counted as one pass.

[0009] S4. The starting point of the next tool movement is offset relative to the previous tool movement. The angle, the movement trajectory of the cutting tool tip is distributed in an arc;

[0010] S5. The roller rope groove can be machined after N passes.

[0011] The above method processes the rope groove of the large roller by clamping the large roller on a large vertical lathe, setting the program of the large vertical lathe to process the rope groove, and offsetting the cutter relative to the previous tool path The complete rope groove is processed after N times of turning, and is formed by being divided into multiple processes, so that the size of the rope groove processed each time is not too large, and the cutting position is adjusted in real time according to the cutting position after each tool path, so that the cut rope groove is more reliable. The method utilizes existing equipment, improves the utilization rate of the equipment, and can process large roller rope grooves.

[0012] Further, the reinforcing frame is a cross reinforcing frame, and the reinforcing frame is welded by channel steel and is connected with the roller by spot welding. The setting can effectively strengthen the strength of the roller and prevent deformation, and the reinforcing frame can be removed after processing.

[0013] Further, the depth of the rope groove is

[0014] Further,

[0015] Further, the cutting edge of the cutter is a circular arc shape.

[0016] Further, the radius of the circular arc cutting edge is equal to the radius of the rope groove.

[0017] The above setting can make the processing process smooth, and the size of the processed rope groove is accurate and the surface roughness is low. BRIEF DESCRIPTION OF DRAWINGS
