Crimped pipe press-fitting unit suitable for overhead contact system dropper machining

Abstract

The invention discloses a crimped pipe press-fitting unit suitable for overhead contact system dropper machining, and belongs to the technical field of overhead contact system dropper machining. The crimped pipe press-fitting unit comprises a servo motor, a speed reducer, a coupling and a twin-twist lead screw; and through corresponding arrangement of external threads with the opposite rotating directions at the two ends of the twin-twist lead screw and corresponding arrangement of mounting blocks on the peripheries of the two ends of the twin-twist lead screw and molds on the mounting blocks,synchronous control over the two molds getting away or close can be effectively achieved, and a non-work state, a clamping state and a press-fitting state of the two molds are quickly switched. The crimped pipe press-fitting unit suitable for overhead contact system dropper machining is simple in structure and easy and convenient to operate, automatic clamping and automatic press-fitting of a crimped pipe can be effectively achieved, the precision and accuracy of clamping and press-fitting of the crimped pipe are ensured, the workload of manual operation in the overhead contact system droppermachining process is reduced, the matched press-fitting efficiency of the crimped pipe and a stranded wire is ensured, the cost of dropper machining is lowered, and the crimped pipe press-fitting unit has good application prospects and promotional value.

Description

technical field [0001] The invention belongs to the technical field of catenary hanging string processing, and in particular relates to a crimping tube pressing unit suitable for catenary hanging string processing. Background technique [0002] With the rapid development of my country's railway construction, new requirements are put forward for the technical quality standards of related components in the railway industry, and the requirements for the construction and maintenance accuracy of driving lines are getting higher and higher. In the railway line, the catenary is an important part to ensure the normal operation of the railway. It is connected to the electric railway power supply line and is responsible for supplying power to the entire electric locomotive traction system and train ancillary equipment. [0003] In the catenary system of the train, the suspension string is an indispensable structure, which is mainly used to stably hoist the contact line under the caten...

AI Technical Summary

Problems solved by technology

[0004] Due to the high requirements on the structural accuracy of catenary suspension strings in application, and the forms of suspension strings are different in different application scenarios, the current processing of catenary suspension strings is often carried out manually, or artificially pre-processed. The prefabrication and production of hanging strings with semi-automatic assembly line operation leads to low production efficiency and poor consistency of hanging strings, high scrap rate, which in turn affects the application cost of catenary hanging strings, and cannot fully guarantee the rapid development of high-speed railways development needs
