According to the crumb-free cutting device of the circular steel tube, a lifting mechanism (4) of an air cylinder or an oil cylinder is arranged on a machine frame (3), the lifting-up or falling-down of the lifting mechanism (4) is driven by a motor (5), a disc slicing cutter (6) is arranged on a cutter frame, a support frame (2) is assembled on the machine frame and below the disc slicing cutter (6), two support rollers (1) capable of freely rotating horizontally are assembled on the support frame (2) side by side, an axis of each support roller (1) is parallel to a rotating axis of the disc slicing cutter (6), a steel tube (G) to be cut is placed on the two support rollers (1), the blade of the disc slicing cutter (6) is V-shaped, and the included angle alpha of the V is 15-22 degrees, and an included angle of a connection line of the axis of the steel pipe (G) and the axis of the disc slicing cutter (6) and a vertical line is 8-15 degrees. The crumb-free cutting device of the circular steel tube is simple in structure, convenient to use, and free of crumbs.

Description

A kind of round steel pipe chipless shearing device
Technical field
The utility model relates to the cut-out equipment of steel pipe, particularly relates to a kind of chipless shearing device of steel pipe.
Background technology
Steel pipe, producing and use procedure, often need to be to long steel pipe cutting, the shearing device of prior art be by flat thin grinding wheel under high-speed rotation with steel pipe cutting, the method is cut off first with the wearing part steel pipe, and incision is jagged, and cutting off in addition has a large amount of metal flying chips in operation, to environment, all influential to product.A kind of chipless cutting-off method is separately arranged, adopt laser cutting, but must have corresponding laser equipment and facility to drop into, cut off mouth as calcination, differ and satisfy surely customer requirements.Therefore, in daily production and processing, urgently wish a kind of convenience, practical cutter for steel tubes.
The utility model content
The purpose of this utility model is for above-mentioned shortcomings and deficiencies of the prior art, intends providing a kind of smear metal that do not have, cutter for steel tubes simple in structure, easy to use.
The purpose of this utility model is realized by following technical scheme.
A kind of round steel pipe chipless shearing device is characterized in that:
Elevating mechanism by cylinder or oil cylinder is set on frame, and elevating mechanism rises or falls by motor (5) and drives, and is arranged on the disk slicer on knife rest;
Below the disk slicer, assemble carriage on frame, configuration level free to rotate two backing rolls arranged side by side on carriage, the axis of backing roll is parallel with the rotation of disk slicer;
Shelve steel pipe to be cut off on two backing rolls;
The edge of a knife of described disk slicer is in the shape of the letter V, and the angle α of V word is 15-22 degree;
The line in described steel pipe axle center and disk slicer axle center, with the angle β of vertical line be 8-15 degree.
Further, the diameter of described backing roll equals 0.6-1.2 diameter of steel tube.
Further, the diameter of described disk slicer is 150-250mm.
Further, described motor is through speed changer driver plate slicer.
Adopt the technical program, during operation, long steel pipe to be cut off is placed on two backing rolls, form a rounded projections arranged, then gauge tap, start the elevating mechanism of cylinder or oil cylinder, allow the disk slicer that is arranged on knife rest by motor-driven fall downwards, at this moment, disk slicer contact steel pipe, the rotation of disk slicer passes to steel pipe, the rotation of steel pipe passes to again the backing roll rotation of two of belows, slowly continue decline disk slicer, steel pipe is cut off under the acting in conjunction of rolling, cutting and push, and does not have smear metal to occur.
It is a kind of simple in structure that advantage of the present utility model and beneficial effect, the utility model provide, the cutter for steel tubes that there is no smear metal easy to use.
Description of drawings
Fig. 1 is the structure chart of the utility model round steel pipe chipless shearing device one embodiment, and disk slicer parts are positioned at the rise Status view;
Fig. 2 is that Fig. 1 disk slicer parts are positioned at and fall the dissengaged positions view;
Fig. 3 is the structural representation of the utility model disk slicer, backing roll and steel pipe fitting, and disk slicer parts are positioned at the rise Status view;
Fig. 4 is that Fig. 3 disk slicer parts are positioned at and fall the dissengaged positions view.
In figure: the 1st, backing roll, the 2nd, carriage, the 3rd, frame, the 4th, elevating mechanism, the 5th, motor, the 6th, disk slicer, G are steel pipes.
The specific embodiment
Further describe structure of the present utility model below in conjunction with accompanying drawing.
A kind of round steel pipe chipless shearing device arranges the elevating mechanism 4 by cylinder or oil cylinder on frame 3, elevating mechanism 4 rises or falls by motor 5 and drives, and is arranged on the disk slicer 6 on knife rest;
Below disk slicer 6, assembling carriage 2 on frame 3, configuration level free to rotate two backing rolls 1 arranged side by side on carriage 2, the axis of backing roll 1 is parallel with the rotation of disk slicer 6;
Shelve steel pipe G to be cut off on two backing rolls 1;
The edge of a knife of described disk slicer 6 is in the shape of the letter V, and the angle α of V word is 15-22 degree;
The line in described steel pipe G axle center and disk slicer 6 axle center, with the angle β of vertical line be 8-15 degree.
In order to reach the purpose of this utility model, the angle α of the edge of a knife V word of described disk slicer 6 is necessary for 15-22 degree; The line in described steel pipe G axle center and disk slicer 6 axle center is necessary for 8-15 degree with the angle β of vertical line, just can reach steel pipe and roll, is being cut off the effect that does not have smear metal to occur under the acting in conjunction of incision and extruding.
The diameter of described backing roll 1 equals 0.6-1.2 steel pipe G diameters, can obtain in scope and cut off preferably effect.
The diameter of described disk slicer 6 is 150-250mm, can reach the cut-out effect.
Described motor 5 according to the rotating speed of motor 5, through speed changer, reaches the cut-out purpose through speed changer driver plate slicer 6.
