Description

Swinging pipe cutting apparatus with multi knife cutter

The utility model relates to a kind of device that is used to cut various metallic conduits, particularly relates to a kind of swing multitool pipe cutter.

As everyone knows, domestic existing various pipe cutters its to manage mechanism admittedly nearly all be three pair rollers that are on the same circumference that 120 ° of angles are distributed on body, because in the practice of construction process, body, roller shaft and be difficult to keeping parallelism by the axis of three objects in Pipe Cutting road, event is deviation slightly, just can increase the running resistance of roller, make body depart from the cut point of setting, so that influence cutting effect.For example: Chinese patent " hand cut device " (GG86203304U), form with the feed cover that has the cutting tool tool rest by a kind of solid pipe box that has three holding screws, except having above-mentioned shortcoming, because can not axial location, so installation accuracy is poor, cutting section is irregular, with pipe fitting axis out of plumb, when cutting than long pipe fittings, also need the operator constantly to help, use inconvenience, and be easy to press from both sides cutter, breaking, handgrip need rotate 360 ° or the like, because prior art has above-mentioned deficiency, has limited being extensive use of of pipe cutter.

The purpose of this utility model be just to overcome above-mentioned the deficiencies in the prior art part and provide a kind of cut effectively various metallic conduits, running steadily, otch is neat and the swing multitool pipe cutter vertical with the pipeline axial line.

The purpose of this utility model is to realize like this, that is: swing multitool pipe cutter, comprise Hough body by upper and lower organization, conjuncted bolt, cutting knife, it is characterized in that a universal mechanism and the multi-cutting machine structure of managing admittedly that is contained on the Hough body, one be stuck in the upper machine body both ends pass through that slide block, bolt connect with it, drive upper and lower sprocket wheel rotation and realize feed and promote complete machine is realized cutting around the rotation of pipe fitting axis driving mechanism.Wherein: universally manage machine admittedly and promote complete machine is realized cutting around pipe fitting axis rotation driving mechanism.Wherein: universal main effect of managing mechanism admittedly is whether the pipeline that no matter is cut has out-of-roundness, unevenness, all can make body and pipeline remain on same axis, make body steady when conduit axis turns round, make the otch in institute Pipe Cutting road smooth and perpendicular with its axis.

Concrete structure of the present utility model is provided by the following drawings:

Fig. 1 is an overall construction drawing of the present utility model;

Fig. 2 is Figure 1A-A cutaway view;

Fig. 3 is the universal profile of managing mechanism admittedly of the utility model.

Below with reference to accompanying drawing concrete structure of the present utility model and working condition are further described.

Referring to accompanying drawing 1-3, the swing multitool pipe cutter of the utility model comprises the Hough body of being made up of upper and lower body 2,3, cutting knife 20, conjuncted bolt 1, it is characterized in that a universal mechanism 26 of managing admittedly that is contained on the Hough body 2,3, multi-cutting machine structure 27 and driving mechanism 28.Wherein:

The universal mechanism 26 of managing admittedly is by being 120 ° of insertion Hough bodies 2 that angle is uniform, in 3 radial holes, its hollow part is equipped with three of spring 30 and is rolled bar 18, universal bearing supports 19 hinged with the sphere that rolls bar 18 and that further connect by bearing pin 31, paired universal bearing support 19 left sides that are installed in symmetrically, the roller set 17 of right both sides, screw rod 32 with the insertion end thread connection of rolling bar 18, handle 14 with the external part Joint of screw rod 32, with the coaxial mounted ratchet 22 of the pair roller in each roller set 17, restriction ratchet 22 turns to the ratchet 23 of (controlling the Hough body with this turns to), and the spring 24 that forces ratchet 23 to withstand ratchet 22 is all the time formed with the nut 25 that the spring base function is arranged.In this mechanism, turn handle 14 can change the distance of three roller set apart from the center, so that adapt to the cutting of different tube diameters.In addition, because each roller set 17 is made up of 4 rollers, certain span is arranged between every pair roller, and joining in addition universal bearing support 19 is that sphere is hinged with rolling bar 18, so, after on three groups of rollers 17 are pressed in by the Pipe Cutting part, even pipe fitting has hole point scar knot or is the elliptical tube face, body also can be fixed on exactly by on the Pipe Cutting part and vertical with the axial line of pipe fitting, thereby guarantees that the otch section is vertical with the pipe fitting axial line, in cutting process, make the complete machine running steady, light.

Multi-cutting machine structure 27 is by three knife bars 16 in the radial hole that is the uniform insertion Hough body 2,3 of 120 ° of angles, and with the upper and lower sprocket wheel 6,15 of knife bar 16 thread connection, toolsetting bolt 13 and cutting knife 20 are formed.Because upper and lower sprocket wheel 6,15 is arranged on the different circumference, so, it is also corresponding with it to realize feed screw 8,9 feed, that be contained in swing arm 5 sides to stir sprocket wheel 6,15 rotations, so that by adjusting the position of feed screw 8,9, cutter is cut in the cutting of realization hilted broadsword, double-pole cutting or three.

Driving mechanism 28 is by swing arm 5, and connect and the feed screw 8,9 that have tightening handle 7,10 of side thread with it 11 is formed with left and right the pawling that the pin that is contained in two inboards is hinged.

The course of work of the present utility model is such: at first, with upper machine body 3 across by on the Pipe Cutting road, to go up then, lower body 2,3 close up, the conjuncted bolt 1 of turn, fastening nut, complete machine just is fixed tightly in by on the Pipe Cutting road, at this moment, as long as pull swing arm 5 along clockwise direction, just can make a left side, pawl and 11 enter Hough body 2 in the right side, teeth groove on 3, driving complete machine turns clockwise around conduit axis, realize cutting, a left side, pawl and 11 stride into different teeth groove in the right side, the amplitude of oscillation just has greatly; little variation; this just help according to the hole down or Ground Operation space and position of human body choose at random the amplitude of oscillation, reach easy to operate purpose.When swing arm 5 was returned in the counterclockwise direction, feed screw 8 or 9 just can be stirred upper sprocket wheel 6 or lower sprocket 15 rotations, and the knife bar 16 of thread connection moves downward thereby drive with it, realizes feed.When only needing one cutter cut, need feed screw 9 is screwed out, make Hough body 2,3 in turning course, feed screw 9 can not contact lower sprocket 15; In like manner, when two cuttves of need cut, need feed screw 8 is screwed out, the size of the depth of cut is then decided by the depth degree of upper and lower sprocket wheel 6,15 teeth groove of feed screw 8,9 insertions, that is: when the top of feed screw 8,9 is positioned at the tooth top portion of upper and lower sprocket wheel 6,15, the angle of revolution of sprocket wheel is little, and the depth of cut is also little; Vice versa.Be symmetricly set on two toolsetting bolts 13 of every knife bar 16 ends, both can be used to clamp cutting knife 20, can be used to again adjust its left and right position, that is: the depth of cut is also little; Otherwise it is right.Be symmetricly set on two toolsetting bolts 13 of every knife bar 16 ends, both can be used to clamp cutting knife 20, can be used to adjust its left and right position again, that is: both three cutting knifes 20 can be transferred on same cross section, it can be transferred on left and right or three cross sections, left, center, right again, so both can reduce the hilted broadsword area of cut, disperse cutting resistance, prolong cutter life, make it to cut brisk, and the phenomenon that can avoid pressing from both sides cutter, knife takes place.

The utility model compared with prior art, it is smooth vertical, easy to install to have an otch, is difficult for the characteristics such as folder cutter, breaking, not only is adapted to ground, also is applicable to the lower operation in hole.
