The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, pipe cutting machine of the present invention, comprise frame 1 and be fixed on the support 2 in frame 1, on support 2, be provided with motor 3, the interior rotation of support 2 is provided with pipe box 4, support 2 is stretched out respectively at the two ends of pipe box 4, one end of pipe box 4 is provided with driven pulley 5, on the output shaft of motor 3, be provided with driving pulley 6, between driving pulley 6 and driven pulley 5, by belt 7, be connected, the other end of pipe box 4 is provided with knife rest 8, on described pipe box 4, slide and be provided with the pushing disc 9 matching with knife rest 8, pushing disc 9 is enclosed within on pipe box 4, on pushing disc 9 circumferencial directions, be provided with a circle groove 10, one side of pushing disc 9 is provided with propulsion plant, propulsion plant comprises the cylinder 11 being fixed on support 2 and is hinged on the pushing ram 12 on support 2, one end of pushing ram 12 is hinged with and advances bearing 13, advance bearing 13 to be positioned at groove 10 and advance the periphery of bearing 13 and the two side of groove 10 to offset, the pin joint place of pushing ram 12 is fixed with V-arrangement depression bar 14, the pin joint of the corner of depression bar 14 and pushing ram 12 is fixed, the piston rod of one end of depression bar 14 and cylinder 11 is hinged, in frame 1, be provided with a stepping guide rail 15 consistent with tubing throughput direction, the direction that the upper surface of stepping guide rail 15 enters from tubing tilts to the direction of going out, the other end of depression bar 14 is hinged with the last item rolling at stepping guide rail 15 upper surfaces and holds 16.
As shown in Figure 3, the upper surface of described stepping guide rail 15 is stepped.In incising pipes, a circle equal thickness is first cut in realization, then feed like this, and then cutting one circle, incremental, is so more conducive to the stability of feed, avoids depth of cut to increase always, produces tubing and beats.In the time of actual production, the length of each step of ladder meets knife rest and turns around, and last item holds 16 and just covers a step.The height of step is unsuitable excessive, avoids jolting.
In order to improve the stability of feed, and cutter feed and withdrawing are steady, as shown in Figure 4, on described knife rest 8, radially slide and be provided with cutter 17, two pairs of 18 and rose reamers 19 of compacting wheel, on cutter 17 and rose reamer 19, be hinged with respectively roller 20, on pushing disc 9, be provided with the guide plate 21 of two insertion knife rests 8, on guide plate 21, be respectively arranged with the skewed slot 22 matching with roller 20, the axioversion of the opening direction of skewed slot 22 and pipe box 4, and pushing disk 9 is in roller 20 lays respectively at corresponding skewed slot 22.Two pairs of compacting wheels 18 are symmetrically distributed on knife rest 8.
For iron filings being discharged fast, avoid the cutting of tubing to exert an influence, in described frame 1, be provided with dust catcher 23, dust catcher 23 is positioned under knife rest 8.
Not inclined to one side when guaranteeing that tubing enters pipe cutting machine, and steadily enter, be positioned at tubing throughput direction and be provided with bracket in described frame 1, bracket comprises the riser 24 being fixed in frame 1, the upper end of riser 24 is provided with V-arrangement supporting plate 25, and supporting plate 25 is met to that end of tubing downward-sloping.
Support 2 is slidably arranged in frame 1 by guide rail 26.The outside, two ends of pipe box 4 is respectively arranged with a pair of Kazakhstan furan 27 and drives the clamping cylinder 28 of breathing out furan 27 work.Breathing out furan 27 is separately fixed on support 2.
The course of work of the present invention is: as shown in Figure 1, tubing enters pipe box 4 from the bracket on the right, when tubing reaches the length that needs cutting, clamping cylinder 28 drives Kazakhstan furan 27 to clamp tubing, then starter motor 3, and motor 3 rotates by driving pulley 6, belt 7 and driven pulley 5 driving sleeves 4, and pipe box 4 band movable knife racks 8 rotate, because pushing disc 9 inserts in knife rest 8 by guide plate 21, so pushing disc 9 also rotates thereupon.Because tubing is to be carried and come by hauling machine above, that is to say that tubing also has certain translational speed, so support 2 is under the effect of tubing, on the guide rail 26 of frame 1, moves.Because stepping guide rail 15 is fixed in frame 1, thus last item hold 16 can on stepping guide rail 15, move.Support 2 is in moving process, cylinder 11 promotes depression bar 14 all the time, making last item hold 16 is pressed on stepping guide rail 15 all the time, because the upper surface of stepping guide rail 15 tilts, therefore last item holds 16 a trend from high to lower, and depression bar 14 clockwise rotates with respect to pin joint, and now pushing ram 12 also clockwise rotates, thereby utilize, advance bearing 13 that pushing disc 9 is pushed away to the right, pushing disc 9 is near knife rest 8.Under the effect of cutter 17 skewed slot 22 on guide plate 21, along knife rest 8, radially move inward, be cutter 17 feeds and tubing is carried out to ring cutting, thereby realize the cutting to large-scale wall thickness tubing, knife rest 8 is in the process of rotating, compacting wheel 18 is clamping tubing all the time, prevents that the long middle bent that causes of tubing from affecting cutting effect.After having cut, can carry out chamfering with 19 pairs of tubing of rose reamer.
