At the problems referred to above, the utility model provides the steel tube cutting machine that a kind of novel structure, efficient are higher, easy and simple to handle, can cut different tube diameters and wall thickness.
The cutting process of the utility model steel pipe is finished as follows: connect power supply, make motor drive slitting milling cutter rotation (principal cutting movement) by main transmission.Manually the swivel feeding wheel makes slitting milling cutter contact outer diameter of steel pipes by a cover depth-feed mechanism.Connect friction clutch by clutch shifter again, make the main motion motion of mechanism pass to circumferential feed motion mechanism.Then, realize that by bevel gear, worm and gear motion slitting milling cutter rotates along the steel pipe that is cut, and promptly carries out circumferential feed motion in the rotation cutting.Can also when cutting thick walled steel tube, constantly make the slitting milling cutter radial feed according to the wall thickness situation of being cut steel pipe simultaneously by the swivel feeding wheel.General circumferential feeding rotates a circle, the depth of cut 4～5mm radially, so to thin-walled (≤5mm) steel pipe, circumferential feeding one circle of slitting milling cutter can cut off steel pipe, for thick walled steel tube, swivel feeding can cut off steel pipe several times.
This steel tube cutting machine, comprise frame, slitting milling cutter, principal cutting movement part and circumferential, the radial feed motion parts, it is characterized in that said slitting milling cutter can carry out circumferentially being cut with feeding radially along cutting steel pipe in rotation (principal cutting movement), by hitch worm gear and swivel bearing being applied mechanically bolted is in the same place, the swivel bearing cover is in the same place with bolted with guiding fork, guiding fork links together by stirring lever pin and poke rod and floating bearing bracket, by three hitch, a swivel bearing cover, a shift fork, a shifting fork pin, a poke rod, stir lever pin for one, a guiding fork, the structure of a floating bearing bracket, realize the circumferential feeding cutting of slitting milling cutter, feed wheel is by gasket ring and worm gear axial location, the internal diameter engagement of the threaded external diameter peace of feed wheel dribbling screw thread, feed wheel rotates relative to the square position and promotes the square position displacement, promote the worm gear of poke rod by trough of belt with the square position with the shift fork of bolted and carry out displacement, make and stir lever pin drive floating bearing bracket together along the groove displacement in the guiding fork, like this by a feed wheel, a square position, shift fork, poke rod, stir fork shaft, guiding fork, the structure of floating bearing bracket realizes the radial feed cutting of slitting milling cutter.This steel tube cutting machine, it is characterized in that comprising two clamping plate in slitting milling cutter rotation (principal cutting movement) part, a driving lever seat, four ball rods, four groups of ball half-watts, two sliding sleeves, two sliding bars and two stage clips, two ball rods are with the clamping plate that are threaded, two ball rods are with the driving lever seat that is threaded, two groups of ball half-watts connect two ball rods and sliding bar with bolt, two groups of ball half-watts connect two ball rods and sliding sleeve with bolt, in order to realize when circumferential, stretch out the variation of sliding sleeve length for adapting to the required sliding bar direction of slitting milling cutter change in location with it during radial feed.
Use this steel tube cutting machine, can be at the construction field (site) and the factory floor operation, stock-removing efficiency is higher, and otch is smooth, and is easy and simple to handle, alleviated working strength of workers simultaneously.This machine cost is low, convenient maintenance, and to general construction and installation, engineering construction and machining manufacturing enterprise all are suitable for.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the overall schematic of steel tube cutting machine.
With reference to Fig. 1, the steel tube cutting machine profile is welded as a whole by frame 29, left bottom plate 26, right base plate 42.Left plate 21, right plate 67, upper cover plate 2, cover plate suitable for reading 80, left socle 14, right support 69 are fastenedly connected as a whole by bolt 24,68,1,19,25,62 and frame.The centre bore of left socle 14 is concentric with the centre bore of right support 69, and the aperture is 200mm, and this machine can cut the steel pipe of external diameter≤200mm.This machine is furnished with the footpath of joining that a cover has a different endoporus aperture and overlaps 12, joins the footpath and overlaps 12 and be threaded with swivel bearing cover 13, can select joining directly of suitable endoporus aperture to overlap 12 according to the outside dimension that is cut steel pipe 59 before this machine operation.After steel pipe 59 was cut position alignment tab milling cutter 79, it is fastening that steel pipe 59 left ends are connected tightening screw rod circumferentially uniform on the left socle 14 8 location by three, it must not be rotated or moves.Connect power supply, start motor 46, drive driving lever seat 72 and rotate by V belt 54, belt pulley 53, key 50, large belt wheel 51, pinion 52, duplicate gear 57, gear 71,2 ball rods 73 with threaded connection on the driving lever seat 72, opposite opened ball half-watt 74 connects as one by bolt 75 and contains the bulb of ball rod 73 and can do universal rotation with respect to bulb, ball half-watt 74 is fixedlyed connected with sliding sleeve 77 by bolt 75 again, is with the end sliding bar 78 that connects ball half-watt 74, ball rod 73 with quadrat method in the sliding sleeve 77.Like this, begin just to pass on the slitting milling cutter 79 that is installed on the floating axle 85 and is clamped by two clamping plate 81, make slitting milling cutter 79 rotations, constitute the main motion of cutting steel pipe 59 through the motion of above-mentioned design of part transmission and power from motor 46.Ball half-watt 74 has guaranteed the smooth transmission of slitting milling cutter 79 main motion on the
