Description

Cut off chamfering control device and pipe cutting machine

Technical field

The utility model relates to and a kind of cuts off chamfering control device and pipe cutting machine, particularly a kind of for cutting off thin-wall circular tube and the cut-out chamfering control device of chamfering and cut off the pipe cutting machine of many for thin-wall circular tube clamped one time.

Background technology

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

1, lathe cuts off chamfer machining mode:

The external diameter of lathe chuck clamping pipe or internal diameter, often expect when will cut off tube wall that pipe swings very large, go to connect also dangerous with hand, tune also will clamp and chamfering for the second time, in addition, the size of institute's chamfering, only with hand strength, does not control by mechanical unified scale, and use follow-rest and tailstock frequently, the low labour intensity of working (machining) efficiency is also large.

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

Clamp the external diameter of pipe with vice, bands for band clamps chamfering expecting to use lathe chuck second time instead after under pipe saw, also will reverse end for end afterwards to clamp chamfering for the third time on lathe.The processing thin-walled pipe of bands for band not only the life-span short, noise is also large, and 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:

From above material pipe diameter, feed is until down sawed-off, the not only sawed-off time is long, and sawed-off after both ends of the surface out of plumb again, by to the material collection of pipe and the carrying of secondary, in the chamfering of the Special chamfering machine clamping material pipe external diameter next used, often occur that pipe radius is lopsided very large, another side does not also pour into angle, the carbide cutter tool often pinching and tipping of die cast, in addition also will along with the difference of pipe thickness, tool position on frequent adjustment rotary head, have impact on the raising of working (machining) efficiency and quality.

4, saw blade or hand operated grinding wheel cut off chamfer machining mode:

The large contaminated environment of noise, end finish difference of cutting, again can not chamfering.

5, the chamfer machining mode of pincers worker file:

Player whose turn comes next's next procedure is with the concentricity of the internal diameter of pipe and pipe two chamfer for working standard, and artificial file chamfering, not only of poor quality, labour intensity is also large, can not meet the requirement of operating accuracy at all.

The processing mode of above five kinds of cut-out chamferings, there is a common ground, in cut-out processing, tape measure used is not only long but also soft, hand-held also inconvenient, have impact on the raising of certainty of measurement, in addition at the external diameter to light-wall pipe, during four times mechanical is fixedly clamped, not only cause the change of the circularity of pipe, cylindricity precision, under also potential impact, road is to expect bore, and two chamfer inclined-planes are the raising of benchmark manufacturing procedure and machining accuracy.

The patent No. is 201210264520.4, the utility model patent that utility model name is called " otch both ends of the surface being carried out to the differential pipe cutting machine of inside and outside chamfered edge processing " simultaneously, after solving the cut-out of circle material pipe, otch both ends of the surface is carried out to a difficult problem for inside and outside chamfered edge processing.But clamped one time only can cut off chamfering one place, this processing scheme, in reduction device fabrication and maintenance cost, reduce the infringement of material pipe to out-of-roundness in clamping external diameter, the upper demand all having improvement to improve of enhancing productivity.

Applicant for the material pipe fabrication design patent No. of small size diameter is: ZL201320588694.6, utility model name is called: " cutting off the pipe cutting machine of chamfering while of chamfering one lathe tool and clamped one time cut-out ", clamped one time can be accomplished, multistage cuts off, and chamfering can be carried out to rib inside and outside the both ends of the surface of otch further, improve production efficiency and product quality, but still need to solve the cut-out problem for Large Diameter Pipeline, long size material pipe, the control cutting off rear chamfering accuracy is also left to be desired simultaneously.
