Abstract
The invention provides a screw friction welding method. A firm integrity is formed through high-heat melting generated by high-speed friction of the thick and thin parts of a screw. The method is characterized by including the steps of firstly, designing and machining the thick and thin parts of the screw; secondly, fixing the thick part of the screw on the chuck of the spindle of a friction welding machine, and allowing the thick part to rotate at high speed; thirdly, fixing the thin part of the screw on the other chuck of a slide carriage, and allowing the thin part to move towards the thick part along the slide carriage; fourthly, immediately cutting off power when the thin part and the thick part are in end face contact high-speed friction and generate high-heat melting; fifthly, slowly cooling the welding parts; sixthly, precisely processing the surface of the screw formed by welding. The method has the advantages that tension tests show that no evident difference exists between the turning moment and the torque of the screw manufactured by the method and those of screws machined by coarse materials, a large amount of manpower and material resources is saved, work efficiency is increased greatly, and the ideal effects of energy conservation and emission reduction and cost lowering are achieved.

Screw mandrel is widely used in the plant equipment such as various bench vices, lathe, is very important a kind of mechanical part, and screw mandrel is due to the purposes characteristic of self, and diameter is widely different.Recent research shows, the processing and manufacturing of screw mandrel is mainly still confined to carry out blank processing with coarse fodder, this coarse fodder blank processing method operation is difficult, but also can cause the significant wastage of the resources such as material in process and artificial, electric power, cause processing cost higher, and yield poorly, there is no the market competitiveness, can not meet people to enhancing product performance, energy-saving and emission-reduction, the requirement that reduces the cost, increase work efficiency.
Summary of the invention
For solving operation difficulty, material and the serious problem of energy waste existing in existing screw mandrel machining manufacture, the invention provides a kind of screw mandrel friction welding method, the method processes thick, thin two parts of screw mandrel by design in advance, then utilize thick, the thin two parts high-speed friction of screw mandrel to produce high heat fusing and form a firmly integral body.The method is simple to operate, farthest utilizes raw material, has saved the energy, has reduced production cost.
The present invention is specifically achieved through the following technical solutions:
A screw mandrel friction welding method, the method produces high heat fusing by thick, the thin two parts high-speed friction of screw mandrel and forms a firmly integral body, and its feature comprises following steps:
(1) two different parts of design processing screw mandrel thickness;
(2) by the thick partial fixing of screw mandrel on the chuck of friction-welding machine main shaft, make its High Rotation Speed;
(3) on another chuck on slide carriage, it is moved to thick part along slide carriage the thin partial fixing of screw mandrel;
(4) when thin part produces high heat fusing with thick part end contact high-speed friction, instant power-off;
(5) welding position is carried out to Slow cooling;
(6) precision processing is carried out on screw mandrel surface welding being formed.
Described friction-welding machine is the equipment of electromagnetic clutch High Rotation Speed that drives through belt pulley speed change by motor.
The High Rotation Speed rotating speed of described step (2) reaches 3600 revs/min.
Described step (4) power-off is immediately to electromagnetic clutch power-off.
Described step (5) Slow cooling refers at 200-350 ℃ and is incubated 2-6 hour.
Described step (6) precision processing refers to removes residue, polishing to screw mandrel surface.
Beneficial effect of the present invention is the screw mandrel that utilizes friction welding method to make, through doing pull test, the screw mandrel that its torque and moment of torsion process with coarse fodder, without significant difference, meet the plant equipment such as bench vice according to People's Republic of China's light industry standard (QB/T 1558.3-1995) quality requirement to screw mandrel, and can save a large amount of human and material resources, reduced raw-material waste, greatly improved operating efficiency, reached energy-saving and emission-reduction, the ideal effect reducing costs.
