Irrotational anchor thread machining device for over-length cable

Abstract

The invention relates to an irrotational anchor thread machining device for an over-length cable. The irrotational anchor thread machining device is reconstructed on a Q1322 pipe threading machine. A main shaft turning head, a tool feeding and driving mechanism, a centre mechanism and a clamping component which is used for clamping the cable are newly added. The clamping component is installed on a sliding box; the main shaft turning head comprises a main shaft chuck backrest disc, a main shaft turning head body, three cutter components, and an additional chuck ring which is connected to the main shaft turning head body. The cutter feeding and driving mechanism comprises a transmission box, a main shifting fork component and a driven shifting fork component. The centre mechanism comprises a centering expansion head, a centering expansion shell, an alignment disc and an adjusting rod. The cable is transversely fed in a manner of moving the sliding box forwards and backwards; and the cutter is fed through the cutter feeding and driving mechanism. According to the irrotational anchor thread machining device for the over-length cable, in the machining process, the cable does not need to be laid straight, and the cable can be directly coiled on a cable coil. The precision of the machined thread is high, the machining efficiency is high, and requirements on operators are low.

Description

technical field [0001] The invention relates to a thread processing device, in particular to an anchor head thread processing device with a non-rotating superlong cable. Background technique [0002] With the strengthening of national infrastructure construction, there are more and more large-scale bridge constructions, and a large number of new-type integral extruded steel strand cables are applied to modern bridge construction. There are only two manufacturers of steel strand cables in China, and the applicant of this application is one of them. [0003] Restricted by the structure of the cable, the adjusting thread of the anchor head of the cable is processed after the entire cable is extruded. At present, there are mainly two ways to process the thread of the anchor head. Install the lathe and turn the thread directly on the lathe. Another processing method is to install a set of tooling similar to water pipe cutting on the main shaft of the lathe to process the thread....

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide an ultra-long pulley that does not need to be straightened during the processing process, but can be directly coiled on the cable reel, and the processed thread has high precision, high processing efficiency, and low requirements on the operator. An anchor head thread processing device that does not rotate the cable to solve the problems of difficult processing, high processing cost, low processing efficiency and poor processing quality
