Abstract

The invention relates to an open reduction method, used to product copier and printer. Wherein, it can replace welding and embedding, to shorten processing time, without changing elements. It comprises that the element via rotation of main axle of lathe generates friction with blade, to reach deformation temperature, via the transverse feeding of lathe, to be compressed and deformed to reduce the open, while its open shape can be fixed via the blade, feeding amount, and feeding numbers.

Description

Aluminum pipe, steel pipe necking down process

Affiliated technical field

The utility model technology is to use lathe that aluminum pipe and steel pipe are carried out reducing processing, makes it to become the axis products of hollow.

Background technology

The processing method of time middle empty class axis products has welding and splices at present, but the globality of splicing is not strong, the loosening easily or disengaging of two ends spindle nose.Weldering trace, weld seam appear again after the welding easily.Can't weld or long processing time when particularly tube wall is thin.

Summary of the invention

This technology can similarly be processed on common lathe, does not need to change any parts on the lathe, can do turning processing after machining at once, the loosening situation in weld seam and two ends can not occur, and process time is short.

This technology is mainly utilized the friction intensification principle of material and the at high temperature yielding characteristic of steel aluminum component.Earlier with tool steel or other material, half one end is processed into the shape of generatrix at aluminium axle or steel axle two ends, becomes the square type body of lathe handle of a knife to be clamped on the lathe cutter platform its another end mill before the processing.Again aluminum pipe to be processed or steel pipe are clamped on the lathe chuck.Start lathe, make the Work piece high-speed rotation.Rotate the feeding handle, make cutter longitudinally move to contact workpiece.At this moment produce friction between cutter and the workpiece, when workpiece temperature constantly raises, when the aluminium axle reaches softening temperature or steel axle and reaches softening temperature, continue the feeding cutter to desired size, workpiece just can be deformed under the condition of high temperature and require shape and size.

The beneficial effects of the utility model are to utilize lathe to be used to replace the welding job of pipe type element without any transformation.Process time is short, processing back solderless trace, and globality is strong.Simple to operate, the workman of meeting lathe can process at one time from being welded to turning.

Below in conjunction with accompanying drawing novel process is further specified.

Fig. 1 and Fig. 2 are the clamping and the manuscripts of this example.

Fig. 3 is the part schematic diagram after this example machines.

Among Fig. 1, earlier workpiece 1 is clamped on the chuck, length is that processing length adds about 20mm after the clamping, squeezing knife tool 3 is fixed on the cutter platform again, and the cutter end face is parallel with workpiece.Concrete processing method: start lathe, the speed rotation that makes workpiece 1 turn left right with per minute 800, quick rotation handle 4 traverse feed cutters 3 contact with workpiece until the end face of cutter 3, continue feeding cutter 0.5mm, cutter this moment cutting workpiece not, but make the certain frictional force of generation between workpiece 1 and the cutter 3, cutter stays for some time at this moment, specifically looking the material and the thickness of extruding, can crimp be principle workpiece can be heated to.The aluminum pipe friction 0.5 fen hour of thickness about 4mm can be continued feeding, up to asking size.If it is longer that extruded length needs, can not hold according to said method to repeat to push from workpiece to get final product.

Fig. 2 is the ongoing schematic diagram of processing.

Fig. 3 is the part schematic diagram after machining.

Claims

1. a novel processing technology can directly carry out reducing processing on engine lathe.

2. novel processing technology according to claim 1 is to utilize machined into, and does not carry out other transformation of the way, can directly carry out next step cutwork after finishing by this processes.

3. novel processing technology according to claim 1 is characterized in that: on lathe, will rotate after the piece-holder, utilize the friction of cutter and workpiece that workpiece is carried out the reducing extruding, and form the workpiece of similar two end axles position external diameter less than endoporus.
