Description
The utility model relates to a kind of tubing shearing device, particularly can with the supporting planetary pipe cutting machine that is used for online production of hot-rolled pipe machine.
In the cut-out of large and medium-sized caliber tubing, Japan Patent J59-69213 discloses a kind of planetary pipe cutting machine, it by milling cutter free-wheeling system, facing cutter around being formed by circumferential rotating mechanism of Pipe Cutting center line (being called for short turnover) and milling cutter feed mechanism.Wherein facing cutter turnover and milling cutter feeding transmission mechanism are by motor, gear, worm gear, worm screw composition, and its shortcoming is to be subjected to milling cutter chipping allowance limit production rate lower, can not be used for online production with pipe mill is supporting; Worm gear need easy to wear are often changed, so consume to be worth higher non-ferrous metal, cost is higher, and when particularly being used for online production and carrying out high production rate work with milling train is supporting, the worm gear wearing and tearing are even more serious, and maintenance cost is higher; When continuous cutting-off high temperature (more than 700-800 ℃) tubing, the heat of tubing can make the lubricating oil in the pipe cutting machine heat up so that be aging, thereby increases the consumption of lubricating oil; Mechanical clutch, adjusting that can not be flexible are adopted in the control of the milling cutter amount of feeding; Equipment size is bigger when cutting big tubing.
In order to overcome the above-mentioned shortcoming of existing planetary pipe cutting machine, the purpose of this utility model provide a kind of can be supporting with the hot-rolled pipe machine, big or middle caliber tubing, the productivity ratio height of continuous cutting-off high temperature (more than 700～800 ℃), consume that non-ferrous metal is few, the flexible planetary pipe cutting machine of adjusting of advance and retreat cutter.
Planetary pipe cutting machine of the present utility model has the free-wheeling system of disk-shaped tool, the circumferential rotating mechanism of disk-shaped tool, the radial movement mechanism of disk-shaped tool, be supported on cannulated sleeve pedestal (10) on the frame (59) by the inside and outside toothed ring gear (33) in bearing (46) and (36) and bearing (34) and (35), be installed on the cutterhead (22) on the gear shaft (16), it is characterized in that at cannulated sleeve pedestal (10) and be cut off heat insulation water collar (51) is installed between the pipe (57), on the decelerator (27) of dc motor output shaft and (39), be connected with impulse generator (50) and (48).
The disk-shaped tool of planetary pipe cutting machine described in the utility model is the disc cutting tool, can adopt different cutting tools according to different disconnect requests, as circular saw bit, circular peripheral-mill, plate-like grinding wheel etc.The configuration of cutter can be that the cutter configuration mode that just also can be taked the multitool configuration by Pipe Cutting footpath size, productivity ratio is looked in hilted broadsword configuration, double-pole arranged opposite and the uniform configuration of three cuttves etc., disk-shaped tool is fixed on the gear shaft (16) by nut (23), disk-shaped tool is realized rotation under the driving of motor (1), thereby tubing is cut.
Be in cannulated sleeve pedestal (10) and be an annular chuck by the heat insulation water collar between the Pipe Cutting (57), one end is supported on the cannulated sleeve pedestal (10) by bearing (52), the other end is fixed on the frame (59) with bolt (53) by screw hole (62), combine as a whole with frame (59), when planetary pipe cutting machine is worked, heat insulation water collar keeps relative static with frame (59), then relative slip is arranged with cannulated sleeve pedestal (10) by bearing (52), giving heat insulation water collar like this, the configuration of drainage system provides convenience, feed the cooling water that certain pressure is arranged in the heat insulation water collar, when cutting off the heat pipe material, the heat of tubing is passed to heat insulation water collar by radiation, take away by the water of discharging, heat insulation water collar has played heat insulation effect, make pipe cutting machine not reason cut off the heat pipe material and increase the consumption of lubricating oil.Subfeeder is inserted in the heat insulation water collar cavity and goes, and is opened on certain position, and the appropriate location that outlet pipe is installed on heat insulation water collar annular endplate is enough to all guarantee that heat insulation water collar is full of water and runs well.
Impulse generator (48) and (50) that connect by shaft coupling are gone up in reduction box (39) and (27) in two dc motors (37) that drive turnover of disk-shaped tool (22) and cannulated sleeve pedestal (10) and disk-shaped tool radial motion, (25), in order to the working speed n of control dc motor
37, n
25And the corner φ of eccentric adjusting sleeve gear shaft (19), can select the impulse generator of all kinds and specification for use by concrete condition, as photo-electric with electromagnetic type, but with photo-electric for well.When being used for the high production rate online production, the high impulse generator of precision can be selected for use, in the ordinary course of things, the low slightly or lower impulse generator of precision can be selected for use.
The rotation of disk-shaped tool (22), radial motion and the circumferential compound motion that has constituted disk-shaped tool that rotates, the working speed of dc motor (25) and (37) should satisfy following relationship around here:
