Double-screwing-direction threaded long screw rod production line and production process thereof

Abstract

The invention belongs to the technical field of screw rod production, and particularly relates to a double-screwing-direction threaded long screw rod production line and a production process thereof.The double-screwing-direction threaded long screw rod production line comprises a quenching and tempering treatment furnace for screw rod pre-heat treatment and an end face milling machine for screw rod end face milling treatment. A second mounting base is inserted through four mounting grooves, so that the distance between a first mounting base and the second mounting base is increased, screw rods with various lengths can be fixed through a positioning sleeve and a connecting sleeve, the applicability is improved, the second mounting base is inserted into mounting grooves with the adaptive lengths according to the lengths of the screw rods, threaded rods are screwed to be fixed to the second mounting base, then the screw rods sequentially penetrate through the connecting sleeve and the positioning sleeve, a clamping base is pressed downwards to fix the screw rods by rotating a positioning bolt on the inner side of the positioning sleeve, supporting of the screw rods is achieved, thensubsequent machining operation can be conducted, the supporting and fixing mode of the scheme is simple, and therefore the adjusting efficiency is effectively improved.

Description

Technical field[0001]The invention belongs to the technical field of screw production, and specifically relates to a double-rotation threaded long screw production line and a production process thereof.Background technique[0002]The double-rotating screw is the main and key part of industrial equipment. The screw must have good tensile, bending and fatigue strength, not only high hardness, wear resistance but also good toughness. It is distributed in metallurgy, machinery, petroleum, and electric power. , Building materials, shipbuilding and other industries.[0003]The existing double-rotating long screws need to be fixed during processing and production, milling, drilling, and rough and fine turning operations. However, due to the different lengths of the screws, the installation method of the support mechanism is too rigid and inconvenient for various The screw of the specification length is supported, which affects the processing operation to a certain extent.Summary of the inventi...

AI Technical Summary

Problems solved by technology

[0003] When the existing double-rotational long screw is processed and produced, the screw needs to be fixed during milling, drilling, and rough and fine turning operations. However, due to the different lengths of the screws, the installation method of the support mechanism is too rigid, which is not convenient for a variety of The screw rod of the specified length is supported, so that the processing operation is affected to a certain extent
