Description
The utility model relates to a kind of device of bending pipe fitting, especially pipe fitting is bent to spiral device.
In the prior art, pipe fitting is not curved the isolated plant of spiral element, but adopt two kinds of fairly simple methods, first method is to be carried out on a garden columnar shaft that semi-round groove arranged by curved pipe fitting, and the spiral internal diameter size of the diameter of garden columnar shaft by by bend pipe spare spirality the time determined.Curve different spiral bend pipes and just need corresponding semi-round groove garden columnar shaft, so not only increased cost, and its garden tube section distortion of the pipe fitting that is bent is very big, what have has just been become waste product by bend pipe spare; Another kind method is being filled up sand in the bend pipe spare, heating then, in the hot spirality that bends to, though can significantly reduce the generation of waste product in this way, curve behind the spiral pipe fitting sand in the pipe be difficult to remove clean, copper pipe especially, the sand that has is with regard in adhesion or the embedding copper pipe inwall, in use, these sands can split away off in the oil circuit, damage Hydraulic Elements.
The utility model provides a kind of isolated plant of bending pipe fitting, and it can curve straight tube the spiral element of qualified differently curved radius, and quality is good, the yield rate height.
For achieving the above object, the utility model can be realized by following scheme: this bending pipe fitting device comprises buncher, transmission mechanism, driving shaft and driven shaft.Be respectively equipped with driving gear and big grooved wheel at driving shaft middle part and upper end, be respectively equipped with driven gear and small grooved wheel at driven shaft middle part and upper end; Along having half identical garden shape groove of diameter on the outer garden of big small grooved wheel; Big grooved wheel just in time contacts with small grooved wheel is in the same plane, and half garden shape groove on the big small grooved wheel formed cavity just in time tightens and is bent pipe fitting in the contact position.
The above-mentioned driving gear and the driven gear number of teeth equate, intermesh; Between big grooved wheel bottom and transmission mechanism, be provided with fixedly half chests body on the driving shaft, between small grooved wheel bottom and transmission mechanism, be provided with movable half chests body on the driven shaft; Movable half chests body both sides are provided with the axis of guide, and fixedly the both sides of half chests body are provided with fairlead, and fixedly half chests body and movable half chests body connect into an integral body by the axis of guide and fairlead; Also respectively be provided with a pull bar in the fixing both sides of half chests body, pull bar is connected with the external distolateral connecting rod of movable half chests, and its connecting rod middle part is provided with and compresses cam and compression axis, and the compression axis skewer goes into to compress in the cam, form a linkage like this, can remove movable half chests body.
After adopting such structure, because the driving gear and the driven gear number of teeth are equal, so driving shaft equates that with driven shaft angular speed direction is opposite; Again since half garden shape groove of big grooved wheel and small grooved wheel formed cavity just in time tightens the pipe fitting that is bent in the contact position, when sheave rotates, produced different frictional force in the pipe fitting both sides, the contacted side of pipe fitting and big grooved wheel makes pipe fitting produce stretcher strain, and make pipe fitting produce compression with the contacted side of small grooved wheel, straight tube just is bent to helix tube like this, can obtain the spiral element of differently curved radius by the revolution of adjusting buncher, so do not exist straight tube to be curved the situation of waste product, product percent of pass height.Be provided with movable half chests body and linkage in addition, can send to easily and be bent pipe fitting and easily the helix tube of bending taken out from sheave.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model bending pipe fitting device;
Fig. 2 is the vertical view of bending pipe fitting device shown in Figure 1;
Fig. 3 is the schematic diagram of bending pipe fitting device shown in Figure 1;
Bending pipe fitting device illustrated in figures 1 and 2 comprises buncher 1, transmission mechanism 2, driving shaft 3 and driven shaft 9, be respectively equipped with at driving shaft 3 middle parts and driven shaft 9 middle parts that the number of teeth equates, intermeshing driving gear 5 and driven gear 11, driving shaft 3 and driven shaft 9 upper ends also are respectively equipped with big grooved wheel 6 and small grooved wheel 8; Along having half identical garden shape groove of diameter on the outer garden of big small grooved wheel; Big grooved wheel 6 and small grooved wheel 8 are in the same plane just in time to be contacted, and the formed cavity 7 of half garden shape groove of its contact position just in time tightens by bend pipe spare.Because the driving gear 5 and driven gear 11 numbers of teeth equate, therefore driving shaft 3 and driven shaft 9 rotating speeds equate and direction is opposite, when sheave rotates, make the pipe fitting both sides produce different frictional force, pipe fitting and big grooved wheel 6 contacted sides make pipe fitting produce stretcher strain, then make pipe fitting produce compression with small grooved wheel 8 contacted sides, straight tube is bent to helix tube like this.
Between big or small sheave bottom and transmission mechanism 2 tops, be respectively equipped with fixedly half chests body 4 and movable half chests body 10 on this external driving shaft 3 and the driven shaft 9, movable half chests body 10 and fixedly half chests body 4 connect integral body of formation by fairlead 17 and the fixed guide axle on movable half chests body 10 both sides 16 on fixing half chests body 4 both sides.Fixedly half chests body 4 both sides also respectively are provided with a pull bar 14, and pull bar 14 links to each other with movable half chests body 10 outer distolateral connecting rods 15, forms a linkage, and connecting rod 15 middle parts also are provided with and compress cam 12 and compression axis 13, and compression axis 13 skewers go into to compress in the cam 12.Rotatably compressing axle 13 makes and compresses cam 12 rotation, when compressing cam 12 and rotate to the released position, movable half chests body 10 is removable, leave fixedly half chests body 4, this moment, small grooved wheel 8 was removed simultaneously, between the big small grooved wheel bigger distance has been arranged, bending helix tube is taken out from sheave easily, also the pipe fitting that is bent can have been sent in the middle of the big small grooved wheel easily.When compressing, movable half chests body 10 cooperates with the axis of guide 16 by guide pin bushing 17 with fixing half chests body 4 and is connected.
Fig. 3 has provided the crooked schematic diagram of bending pipe fitting device, and the number of teeth of two gears equates Z among the figure
1=Z
2, so the angular speed of driving shaft 3 and driven shaft 9 equates.The radius R of big grooved wheel 6 is greater than the radius r of small grooved wheel 8, and the linear velocity WR that has produced big grooved wheel 6 outer gardens thus is bigger than the linear velocity Wr in small grooved wheel 8 outer gardens.Therefore straight tube and big grooved wheel 6 contacted sides are stretched, and are extruded with small grooved wheel 8 contacted sides, and straight tube is realized helically bent with regard to being bent to the garden arc like this.Can obtain the toroidal bend of differently curved radius by the revolution of adjusting speed governing 1, this apparatus structure is simple, and applicability is strong, product percent of pass is high.
