Abstract
The utility model discloses an online roll-cutting machine for a steel pipe. The machine comprises a rack, a motor, a rotating roller and roll-cutting structures. The motor is arranged on the rack. One end of the rotating drum is connected with a main shaft of the motor through a belt. The roll-cutting structures are arranged in the rotating drum. The bottom of the rack is supported on a guide rail through rollers. Three round holes are uniformly formed on the same circumference of the rotating drum. Each roll-cutting structure comprises a support frame and a cutting tool arranged on the support frame on the inner side of the rotating drum. Each support frame has a transverse H-shaped design. The transverse H-shaped support frames are clamped in the round holes. Springs are arranged between the exteriors of the round holes and the support frames. The machine is simple in structure; the three round holes are uniformly reserved on the same circumference of the rotating drum, and the transverse H-shaped support frames are arranged in the round holes, so that the machine is convenient to use; and moreover, a rotating drum roll-cutting mode is adopted, and is high in cutting efficiency, low in noise, high in cutting quality and rational and practical in structure compared with a flying saw cutting mode of the conventional technology.
Description
Technical field
The utility model belongs to steel pipe cutting technique field, is specifically related to the online slitting mill of a kind of steel pipe.
Background technology
Slitting mill is mainly used in the cutting of steel pipe, traditional main employing of steel pipe cutting flies to saw cutting on line, kerf quality is bad so on the one hand, there is burr, another also exists the sawing process noise larger, seriously polluted, and slitting mill is to complete the cutting to steel pipe under the effect of revolving force by the cutting tool in swivelling pipe, its noise is little and kerf quality is better, yet the cutting tool of the slitting mill of prior art is to complete cutting process by chute and gear, existence due to gear, make the slitting mill cutting accuracy be subject to certain impact, and gear is also generally by the hydraulic system complete operation, structure is comparatively complicated, cost is higher.
Summary of the invention
The purpose of this utility model is to provide the online slitting mill of a kind of steel pipe simple in structure, that cut quality is good.
The technical scheme that realizes the utility model purpose is the online slitting mill of a kind of steel pipe, comprise frame, be arranged on the motor on frame, the swing roller that one end is connected by belt with electric machine main shaft and be arranged on the rolling cut structure in swing roller, the bottom of described frame by roller supporting on guide rail, evenly be provided with three circular holes on the same circumference of described swing roller, described rolling cut structure comprises bracing frame and is arranged on bracing frame, the cutting tool of described swing roller inboard, support frame as described above becomes the design of " work " word, described " work " shaped support frame is fastened in described circular hole, be provided with spring between the outside of described circular hole and bracing frame.
Be provided with locating slot on described circular hole, support frame as described above is provided with the anti-rotation projection of the vertical setting matched with described locating slot, and described anti-rotation projection is arranged in described locating slot.
Its operation principle is summarized as follows: starter motor, swing roller starts rotation under the effect of motor, when rotating to certain speed, under the effect of centripetal force, when centripetal force is greater than the elastic force of spring, " work " shaped support frame starts to the swing roller medial movement, inner cutting tool is progressively contacted with cut part, and complete cutting, when motor stops, the rotating speed of swing roller is slack-off gradually, the elastic force of the spring of " work " shaped support frame is greater than centripetal force, bracing frame is outwards resetted, cutting tool is resetted, complete once cutting.
The utlity model has positive effect: on simple in structure, the same circumference on swing roller of the present utility model, evenly have three circular holes, and be provided with " work " shaped support frame in circular hole, easy to use, and employing swing roller rolling cut, comparing the sawing that flies of conventional art cuts, cutting efficiency is high, and noise is little and cut quality is high, practicality rational in infrastructure.
The accompanying drawing explanation
For content of the present utility model is more likely to be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that A-A in Fig. 1 is to cut-away view;
The structural representation that Fig. 3 is circular hole and bracing frame combination.
The specific embodiment
(embodiment 1)
Fig. 1 to Fig. 3 has shown a kind of specific embodiment of the present utility model, and wherein Fig. 1 is structural representation of the present utility model; Fig. 2 is the structural representation that the A-A in Fig. 1 is circular hole and bracing frame combination to cut-away view: Fig. 3.
See Fig. 1 to Fig. 3, the online slitting mill of a kind of steel pipe, comprise frame 1, be arranged on the motor 2 on frame 1, the swing roller 4 that one end is connected by belt 3 with motor 2 main shafts and the rolling cut structure 5 be arranged in swing roller 4, the bottom of described frame 1 is supported on guide rail 7 by roller 6, evenly be provided with three circular holes 41 on the same circumference of described swing roller 4, described rolling cut structure 5 comprises bracing frame 51 and is arranged on bracing frame 51, the cutting tool 52 of described swing roller 4 inboards, 51 one-tenth " work " word designs of support frame as described above, described " work " shaped support frame 51 is fastened in described circular hole 41, be provided with spring 53 between the outside of described circular hole 41 and bracing frame 51.
Be provided with locating slot 411 on described circular hole 41, support frame as described above 51 is provided with the anti-rotation projection 511 of the vertical setting matched with described locating slot 411, and described anti-rotation projection 511 is arranged in described locating slot 411.
Its operation principle is summarized as follows: starter motor, swing roller starts rotation under the effect of motor, when rotating to certain speed, under the effect of centripetal force, when centripetal force is greater than the elastic force of spring, " work " shaped support frame starts to the swing roller medial movement, inner cutting tool is progressively contacted with cut part, and complete cutting, when motor stops, the rotating speed of swing roller is slack-off gradually, the elastic force of the spring of " work " shaped support frame is greater than centripetal force, bracing frame is outwards resetted, cutting tool is resetted, complete once cutting.
Obviously, above-described embodiment of the present utility model is only for the utility model example clearly is described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection domain of the present utility model.
