Method and device for processing and manufacturing braided lead head of oil pumping unit

Abstract

The invention provides an oil pumping unit hair pigtail lead head machining and manufacturing method and device and belongs to the technical field of oil field oil pumping unit repair and maintenance. In the operating process, the two ends of a steel wire rope well cut without reserving allowance are fixed to a support together, a hammer is used for striking a lead head into the steel wire rope through a steel wire rope through hole in a working end face so that a certain end of the steel wire rope and the tail end of the lead head can be flush and fixed firmly, a steel nail with the size of 8 mm*35 mm is smashed into the steel wire rope center in the tail end of the lead head so that the diameter of the steel wire rope can be enlarged, then three bolts with the front ends possessing taper and the diameter phi of 12 mm are screwed into bolt fixing holes, the bolts are embedded in gaps of the steel wire rope and cut off from the cylinder surface of the lead head after achieving force of a certain degree, and the tail end is sealed through electric welding.

Description

technical field [0001] The invention relates to a method and device for processing and manufacturing a braided lead head of an oil pumping unit, and belongs to the technical field of maintenance of oil pumping units. Background technique [0002] When the hair braid is made, two people must cooperate to complete it. Cut the steel wire rope to the required size and leave 2cm margin at both ends, put the existing lead head into the steel wire rope from the working end to leave a margin, fix it on the bench vise, and use gas welding by one person to roast the steel wire rope margin head for each single strand Red, another person bends the roasted red single-strand steel wire with pliers, and then smashes the steel wire into the expansion hole of the lead head with a steel drill hammer. Repeat the above method to smash each strand of steel wire in order, and finally use gas welding Roast the remaining ends of the steel wires red, beat all the steel wires into the lead head hole...

AI Technical Summary

Problems solved by technology

It takes more than an hour to make a braid, which is time-consuming and labor-intensive. It is also necessary to prevent burns. Because the heating time is too long, the strength of the hook of the steel wire rope is greatly reduced. The well affects production, and the braids need to be remade, resulting in waste of materials
