Abstract
A double-headed screw machining method includes setting screw lead as a, and setting pitch as s; firstly, turning a first screw thread, allowing the screw lead to be a, remaining a retracting groove, and retracting; turning reversely, returning to a starting point, allowing a workpiece to rotate to a center degree, and dividing a thread on the circumference of the end face of the screw thread; allowing a carriage of a lathe to move backwardly for a pitch s, then turning a second screw thread, and completing one head screw turning after multiple machining; then disassembling the workpiece, rotating for 180 degrees, clamping to the lathe, and turning screws on the other head; quenching a machined screw at the quenching temperature of 150 to 200 DEG C, cooling and performing annealing heat treatment, and adjusting the metallurgical structure of metal to meet the requirements. The screw lead a ranges from 1 to 4mm. The method is adaptable to producing double-headed screws with a long screw lead, and the screw produced by the method has the advantages of high accuracy, short periods, good quality, less steps and material efficiency.
Description
Technical field
The invention belongs to field of machining, particularly a kind of processing method of double thread.
Background technology
The continuous protruding lira spiral yarn shaped, that there is particular cross section of making on cylinder or circular cone bolt two head surfaces, for connecting bolt and nut, i.e. the screw thread of stud
Conventionally adopt at present the method for turning, but processing method is loaded down with trivial details conventionally, complexity, cycle production time is long.
Multiple-threaded conventional method for splitting has: axially divide collimation method: be to utilize upper slide rest to move, separated time in the helical pitch of screw thread, is divided into three kinds of upper slide rest scale method, dial gauge method and slip gauge methods, is applicable to directly enter method turning fine pitch multi start thread.Circumference divides collimation method: be to use changing of workpieces to cross certain angle separated time on the end face circumference of screw thread, according to different situations, can select respectively gear number separated time, Special indexing dish separated time, clasp nut adds the methods such as thread chasing dial separated time and pattern separated time, is applicable to a number is many, helical pitch is large multi start thread and multiple threaded worm turning.Current processing method is comparatively loaded down with trivial details to be unfavorable for producing.
Summary of the invention
The invention provides a kind of processing method of double thread, the accuracy of thread that this method is made is high, and the cycle is short, and quality is good, and step is few, saves material.
A processing method for double thread, comprises following technical process:
If lead is a, pitch is s.
First car article one threaded line, lead is a, reserves escape, withdrawing simultaneously.
Oppositely starting point is return in turning, makes changing of workpieces cross certain angle separated time on the end face circumference of screw thread.
The planker of lathe is a mobile pitch s backward, and then Vehicle Processing second threaded line, through repeatedly processing, completes the turning of the screw thread of.
Then unload workpiece, turn over 180 degree, again clamping to lathe, the screw thread of turning other end.
Finished screw rod is carried out to modifier treatment, refining temperature 150-200 degree Celsius, the heat treatment of withdrawing from a secret society or underworld gang after cooling, adjusts the structure of metal to reaching requirement.
Lead is that a is 1-4 millimeter.
Its advantage is:
This method be applicable to make long helical pitch double thread bar, the accuracy of thread that this method is made is high, the cycle is short, quality is good, step is few, saves material.
