Description

Tube-severing machine for cutting metal tube and cement tube

The utility model relates to a kind of pipe cutter, more particularly relates to a kind of pipe cutter that is used for cutting metal pipe and armored concrete pipe of cement.

Carry in construction and installation in the various pipeline engineering such as running water, coal gas, oil, often must solve the cutting problem of pipe because of needs, particularly solve in the tubulature road and cut, at present creeping-type pipe cutting machines, fluid pressure type tube extruding machine used more because of damage needs the pipe in the maintain and replace, the electrodynamic type pipe cutter, the hand pipe cutter, but because of its unreasonable structure, therefore the caliber scope of cutting is narrower, generally about the poor 100mm in footpath, and be limited to the cutting metal pipe and can't cut the armored concrete pipe of cement.Along with the development of China's town and country urban construction, adopt the cement water-supply-pipe that cost is low, antiseptic property is good more and more widely, so people press for a kind of pipe cutter that can cut pipe of cement.

But the purpose of this utility model provides a kind of not only cutting metal pipe of rational in infrastructure, electronic, dual-use manual but also can cut the pipe cutter of armored concrete pipe of cement.

The purpose of this utility model is achieved by the following technical solution.

The utility model by the support that mechanic jacks is installed, have hinge type body, knife rest and the gearbox of forming clamp mechanism by four rhizoid bars and form, it is characterized in that: engine body exterior one side has a circumference guide rail, have one to be complementary with the circumference guide rail and on the described knife rest, a band dovetail groove is arranged on it and the middle carriage of cutter sweep is installed along the saddle of circumference guide rail rotation.One pair of gear ring interlock of splitting in the pinion of gearbox end and the body makes gear ring rotate the drive saddle in body and rotatablely moves along the circumference guide rail.Cutter sweep on the middle carriage, be made of cutter spindle, screw mandrel and cutter, two cutter spindles are loaded on the middle carriage side by side, and its lower end is installed carbide cutter tool and saw blade cutter respectively, be provided with screw mandrel in the cutter spindle, control cutter spindle along the pipeline radial motion by the handle of its end.One feed screw is arranged on the middle carriage, and there is a sprocket wheel its upper end, the saddle rotation, and middle carriage rotates thereupon, thereby stir the pile crown collision of sprocket on sprocket wheel and the body, make sprocket wheel rotate an angle, drive the middle carriage feeding, realize autofeed, therefore, the amount of feeding of cutter is controlled by the pile crown adjustment.

When on ground, during storehouse or workshop cutting pipeline, only need pipeline is hung onto on the V-type cylinder of jack, along cylinder pipeline is pushed into and passes body center to the position that needs cutting, adjust four rhizoid bars on the body, the fit adjustment knife rest, after pipeline being adjusted to the cutting center of cutter, with its clamping.Start electronic or manual gearbox, make the directly gear ring interlock of splitting of a pair in body of pinion in the gearbox, driving gear ring rotates in body, the saddle that gear ring one side and body circumference guide rail are complementary rotates along the circumference guide rail, middle carriage on the saddle rotates thereupon, the standard model unit head of installing on the middle carriage can carry out milling, grinding, chamfering, cutting to pipeline.As need the pipeline of having adorned is carried out maintain and replace, only need to remove support, body upper lift ring screw is unclamped, open body and snap into by on the Pipe Cutting road, fastening lifting bolt is adjusted clamping device, makes pipeline and machine form the rigidity one, can cut.

When cutting on the tube wall during thicker metal tube, two blades before and after only needing to install on the middle carriage, a first from left is right to be adjusted along the pipeline axial dislocation, gets final product two cuttves and cuts simultaneously, and the cutter grooving of this moment is wideer than cutter, can not cause knife and swaging clamp.

When cutting armored concrete pipe of cement, two cuttves are installed on middle carriage, an anti abrasive carbide cutter tool is adorned in the front, be used to cut cement, stone, the concrete of yellow sand, the machine hacksaw blade cutter (also available common machine hacksaw blade rubs and is clipped in the tool rest) of a high-speed steel is adorned in the back, when the front carbide cutter tool cuts to reinforcing bar, return the front cutter by the screw mandrel in the handle control cutter spindle, saw blade cutter with the back cuts reinforcing bar again, it is sawed-off with reinforcing bar promptly to utilize saw blade to center on pipeline, promptly finishes cutting with the remaining concrete part of front carbide cutter tool cutting again after reinforcing bar is sawed-off.

The utility model has the advantages that:, along the rotation of the circumference guide rail on the body, drive cutter and carry out the pipeline cutting, so otch is straight by saddle 1, because the utility model is rational in infrastructure, and body, pipeline all do not rotate during work.

2, since the feed system of cutter and cutter in a side of body, during use, not fragile body and cutter are two-pass control, it is big therefore to cut stroke.

3, the utility model not only can milling, grinding, chamfering, cutting metal pipe and can cut the pipe of cement of armored concrete.

The utility model will be further described in conjunction with the accompanying drawings by the following examples.

Embodiment:

(referring to Fig. 1,2,3,4) the hinge type body (1) that has a screw mandrel (5) that has four roots and tops band handles (6) to form clamp mechanism on the support (12) of mechanic jacks is installed, the outside side of body (1) has a circumference guide rail (2), be complementary with circumference guide rail (2) and along the middle carriage (7) that a band dovetail groove is arranged on the saddle (4) of its rotation, the cutter spindle (8) that two lower ends are equipped with carbide chip (10) and saw blade cutter (11) respectively is housed on it side by side, in cutter spindle (8), be provided with screw mandrel, control cutter spindle along the pipeline radial motion by the handle of its end, middle carriage has a feed screw on (7), there is a sprocket wheel (9) its upper end, saddle (4) rotates a circle, middle carriage (7) rotates thereupon, thereby stirs the pile crown collision of sprocket on sprocket wheel (9) and the body, makes sprocket wheel (9) rotation one angle, drive middle carriage (7) feeding, thereby realize autofeed.Gearbox (3) is installed on the body.One pair of gear ring interlock of splitting in pinion that gearbox (3) is terminal and the body makes gear ring rotate the drive saddle in body and rotatablely moves along the circumference guide rail.
