Embodiment Construction

[0016] Such as figure 1 As shown, the manufacturing method of the reel variable-pitch broken-line rope groove of the present invention is the starting point control method, the method for maintaining the consistency of the inflection point, and the variable-pitch broken-line rope required for processing the reel variable-pitch broken-line rope groove on a large sleeping car. The processing method of the groove, the processing and manufacturing method composed of the track forming method of the section point of the rope groove, A, the starting point control method:

[0017] The drawing design has clear requirements for the starting point, and controlling the starting point position is of great significance to ensure the consistency of the inflection point. According to the manufacturing process, after the rough turning of the outer circle of the workpiece is completed, it is installed on the machine tool with large tooling, and the positioning is strictly aligned. First select...

Abstract

The invention discloses a processing and manufacturing method for a winding drum variable pitch broken line rope troughs, consisting of a starting point control method, an inflexion consistency keeping method, a variable pitch broken line trough processing method and a rope trough section point track forming method which are required when the winding drum variable pitch broken line rope trough is processed on large sleeping car. The winding drum variable pitch broken line rope trough processed by utilizing the manufacture method has the advantages of meeting design requirement, improving process quality, leading the process and manufacture of the winding drum variable pitch broken line rope trough to come true, providing equipment guarantee for large hydro-junction engineering and mine deep well exploitation and having wide application and popularization value.

Description

Technical field: [0001] The invention belongs to the technical field of reel rope groove processing and manufacturing, and in particular relates to a method for processing and manufacturing a reel variable-pitch broken line rope groove. Background technique: [0002] Hoists and mine hoists usually use drums to rotate and wind steel ropes to lift gates or materials. The rope grooves on the drum are mainly for the convenience of rope arrangement, to reduce the friction and extrusion between the steel ropes, and to prevent the rope from being stuck, and these are of great significance to improve the service life and reliability of the steel ropes. [0003] Generally, the rope groove of the reel is a spiral rope groove, and the processing mainly adopts the method of planing grooves on a flat plate and then rolling, or turning on a large horizontal car by turning threads. These methods are acceptable for processing helical rope grooves, but not for processing broken line grooves...
