Description

A kind of pipe end groove make-up machine

Technical field

The present invention relates to the welding of a kind of steel pipe or moulded the auxiliary equipment that uses in the bonding construction of pipe, particularly a kind of pipe end groove make-up machine.

Background technology

Existing steel pipe welding conditions requirement influences the pipeline construction quality for fear of weld defect in the time of the steel pipe butt joint, must carry out groove at the steel pipe welding ends and handle, and just carries out chamfering at welding ends;

Block steel pipe through regular meeting in the existing pipeline construction and carry out pipe fitting and install or manage butt joint, on-the-spotly generally use steel pipe groove make-up machine or utilize the angle grinding machine or gas welding is carried out the groove moulding to pipe end, the use electric beveler that also has; But, carrying out groove with the angle grinding machine, labour intensity is bigger, and efficient is lower; Use gas welding to be only applicable to carbon steel pipe, can not carry out groove to stainless steel tube and handle; And the electric beveler cost is higher and equipment receives specification limits, and on-the-spot universal use is less.

That uses in the pipeline construction also has a kind of pipe of moulding; Mould the bonding mode of the general employing of pipe butt joint and connect, according to the related specifications requirement, in order to guarantee bonding quality; Also to carry out the groove moulding at the bonding pipe pipe end of moulding; The method of existing on-the-spot groove moulding is to use angle grinding machine polishing moulding, and efficient is low on the one hand, and the groove Forming Quality is relatively poor on the other hand; A kind of in addition mode is to adopt the chamfering spanner to carry out the groove moulding, and to carry out the groove moulding inconvenient but this kind chamfering spanner is moulded pipe to major diameter.

Summary of the invention

Technical problem to be solved by this invention provides a kind of pipe end groove make-up machine, and it effectively improves the on-the-spot groove shaping efficiency of pipe end, improves the groove Forming Quality, and can reduce construction enterprises' equipment cost.

For solving the problems of the technologies described above, the technical scheme that the present invention adopted is: a kind of pipe end groove make-up machine is characterized in that: the groove shaped device that comprises central shaft, is fixedly mounted on the fixture of central shaft one end and is fixed on the central shaft middle part; Said fixture at least two structures identical and be distributed in the slider-crank mechanism on the central shaft circumference;

Said slider-crank mechanism comprises crank, connecting rod, fixed cover, sliding sleeve and setscrew nut; Said fixed cover is located at the central shaft left end; Journal stirrup on said crank one end and the fixed cover is hinged, its other end articulated linkage; The other end of said connecting rod is hinged with the journal stirrup of being located on the sliding sleeve circumference; Be slidingly matched between said sliding sleeve and the central shaft; Said setscrew nut contacts with the sliding sleeve right side and cooperates with central axle threads; Said crank and connecting rod hinge point are provided with support claw.

Said groove shaped device comprises cutterhead, the driving-disc of being located at the cutterhead right side of being located at said setscrew nut right side, the feed nut that cooperates with central axle threads of being located at the feed dish on driving-disc right side and being located at feed dish right side; Said cutterhead and driving-disc are slidingly matched with central shaft respectively; Said feed dish cooperates with the central shaft lead key; Be but that the radial groove of rectangle is provided be uniformly distributed with and knife rest radiai adjustment around its axis by means of the cross section on the said cutterhead left surface; Between said driving-disc left surface and the cutterhead right flank detent mechanism is set; Also be fixed with handle radially on the said driving-disc outer rim; Said feed is faced left and is arranged with two hump shape convexities on the side, and driving-disc right flank and the feed side of facing left is suitable.

Said knife rest is the rectangular strip structure that the middle part is provided with screwed hole, and its outer end is by means of bolt installation forming cutter; Said knife rest is by means of being bolted on the cutterhead left surface; Radially rectangular channel bottom on the said cutterhead left surface is provided with the screwed hole that is used for fixing knife rest of at least two radial equipartitions.

Said support claw comprises basic pawl and is fixedly mounted on the engaging nail on the basic pawl by means of screw rod.

Be arranged with two hump shape convexities on the said driving-disc left surface, face left side view and driving-disc of feed is suitable

The employing beneficial effect that technique scheme produced is: utilize two toggles realization central shafts that are symmetrically set in central shaft one end perhaps to mould the location on the inside pipe wall at steel pipe to be processed, at least two moulding cuttves are set, and perhaps moulding the mouth of pipe directly adjusts the moulding cutter position according to steel pipe to be processed on the cutterhead left surface; The hand-turned driving-disc drives the cutterhead rotation; And driving-disc right flank and feed are faced left delivering gear are set between the side, also in feed, realize the moulding of pipe end groove in the driving-disc rotary course; This shaping machine structure is simple; Need not the power set that provide external, only need manually-operated can accomplish steel pipe or mould the moulding of pipe pipe end groove, can guarantee the steel pipe welding quality or mould the pipe bonding quality; Can also improve efficiency of construction, for construction enterprises reduce equipment cost.
