Abstract

A cutting and chamfering integrated lathe tool and a pipe cutter capable of clamping, cutting and chamfering at one time belongs to pipe processing equipment. A main cutting edge is arranged on the front cutter face in the front of a cutter handle, two symmetrical V-shaped grooves are respectively formed on two auxiliary cutting edges, so that both cutting and chamfering can be realized, the operation is flexible, and changing different lathe tools during chamfering is avoided. The pipe cutter adopts the cutting and chamfering integral lathe tool; a pushing bearing, a cone wedge push pipe and a plurality of cone wedge pipes, which are sequentially mounted on a cylindrical shaft, are connected together. Under the pushing action of a clamping cylinder piston and a conical head, a material pipe is firmly clamped by the external expansion of a C-shaped ring. The cutting and chamfering integrated lathe tool mounted on a sliding shaft lathe tool cutter rest can cut a plurality of pipes with different lengths and meanwhile chamfer the internal arris and the external arris of two end surfaces of notches within the range of a cone wedge pipe hollow cutter groove, in the process of material pipe cutting cutter withdrawing, on one set equipment and in the process of clamping the internal diameter of a thin-walled circular pipe.

Description

Cut off chamfering one lathe tool and clamped one time and cut off the pipe cutting machine of chamfering simultaneously

Technical field

The utility model relates to a kind of for cutting off the cut-out chamfering one lathe tool of thin-wall circular tube and the pipe cutting machine that clamped one time cuts off while chamfering, particularly relate to a kind of in clamped one time, can length cut off many, rib inside and outside otch both ends of the surface is carried out to the lathe tool of chamfer machining simultaneously, and the pipe cutting machine that adopts this lathe tool.

Background technology

In industrial production; thin-wall circular tube after cutting off also requires rib inside and outside otch both ends of the surface to carry out chamfer machining, also requires in the process of clamping pipe simultaneously; the circularity precision to material pipe can not cause damage, at present traditional Pipe Cutting processing mainly contains following four kinds of processing modes.

1, lathe cuts off chamfer machining mode:

Lathe chuck clamps external diameter or the internal diameter of pipe, often expects that pipe swings very large in the time of will cutting off tube wall, goes to connect also dangerous with hand, and tune also will clamp and chamfering for the second time, and uses frequently follow-rest and tailstock, and working (machining) efficiency is low.

2, sawing machine adds the cut-out chamfer machining mode of lathe:

With bench vice, clamp the external diameter of pipe, after bands for band is lower pipe saw, use lathe chuck instead and clamp for the second time chamfering, also will on lathe, reverse end for end to clamp for the third time afterwards chamfering, bands for band cuts off thin-wall circular tube, and not only noise is large, also often collapse tooth, the combined efficiency of these two kinds of equipment is not high yet.

3, sawing machine adds the cut-out chamfer machining mode of Special chamfering machine:

Because bands for band cuts off after pipe, often do not guarantee the perpendicularity of end face and tubular axis line, at the Special chamfering machine next using, clamp in the chamfering of material pipe external diameter, often occur that pipe radius is lopsided very large, another side does not also pour into angle, and the carbide cutter tool of die cast is pinching and tipping often, in addition also will be along with the difference of pipe thickness, readjust the tool position on rotary head, affected the raising of working (machining) efficiency and quality.

4, saw blade or hand operated grinding wheel cut off the chamfer machining mode of circular cone cutter or file

The large contaminated environment of noise, circular cone cutter only can voltage regulator tube end face the angle of the inside, the angle of outside not, and file chamfering, labour intensity is large, efficiency is low, of poor quality.

Above four kinds of processing modes that cut off chamfering, there is a common ground, at the external diameter to light-wall pipe, in mechanical being fixedly clamped, not only cause the circularity of pipe, the change of cylindricity precision, also under potential impact, the raising that is benchmark manufacturing procedure and machining accuracy of material bore is take in road.

The patent No. is 201210264520.4, and denomination of invention is the patent of invention of " simultaneously otch both ends of the surface being carried out the differential pipe cutting machine of inside and outside chamfered edge processing ", has solved after round material pipe cut-out a difficult problem of otch both ends of the surface being carried out to inside and outside chamfered edge processing.Power in scheme, it is extensive that transmission and control arrange coverage, and the external diameter of clamping material pipe, is finally cut off by 2 group of 4 cover on rotary head and chamfering tool completes.This processing scheme, all has to the infringement of out-of-roundness, on enhancing productivity the demand improving of improving in clamping external diameter reducing device fabrication and maintenance cost, minimizing material pipe.
