Description
Technical field
The utility model is the tubing processing taper thread rolling mill of using about for example processing and forming such as gas pipe and pipe joint.
Background technology
In general, the method that forms taper thread in the end of pipe has two kinds of machining and plastic workings.With the method for machining is to wait wall thickness part with gradient ground excision pipe with lathe, forms screw thread with shape.Therefore compare with not cut thicker position, the meat at useful groove position thick (cut back) just becomes very thin on mechanical strength, and its result is to form problem on the intensity or on the decay resistance.On the other hand, be with other machineries pipe to be formed the plastic working of the taper surface of needed taper thread in advance with the method for plastic working in the end of tubing, use threaded rolling running roller forming cone screw thread then.Have the multiple operation screw-thread rolling machine complex structure of pressing mechanism and rolling mechanism simultaneously, volume is big, for gas piping such engineering of mating formation, needs the roving operation occasion loaded down with trivial details inconvenience of operation that just seems.The processing of existing tubing with taper thread rolling method is: construct a rolling head, make this rolling head have that several rollings are centered around rolling head axis circumferencial direction with running roller and the pitch of the defined that staggers distribution installation on axis direction.These rollings have the circular conical surface part that equates with desirable taper angle separately with running roller.Their (rolling running rollers) are made up of two positions: one is to become skewed installation with the angle of inclination corresponding to desirable screw thread effective diameter place lead angle with the tubing axis, the band ditch position of using as roll forming; Another is adjacent with band ditch position with this roll forming, and is bigger slightly than the tapering of above-mentioned conical surface part, the taper band ditch position of using do extrusion modling.Make that this rolling head is relative with tubing to turn round,, and on the end face of tubing, carry out tapering extrusion process and squeezing thread processing operation very longly by the rolling running roller by relatively moving of above-mentioned rolling running roller or tubing.Be described as follows with reference to accompanying drawing 7～accompanying drawing 10: rolling running roller 10 has the circular conical surface part that equates with desirable taper angle.It is made up of two positions: one is the roll forming screw thread position 1 (for example becoming the taper seat of 1 ° of 47 ' angle with the running roller axis X) with the lead angle θ that approximately equates with desirable screw thread effective diameter place lead angle; Another is adjacent with this roll forming screw thread position 1, have the tapering bigger slightly (for example 8 °) than above-mentioned conical surface part tapering, the screw thread position of using do extrusion modling 3,7th is for running roller 10 being installed to rolling head 9 described later (Fig. 8) is gone up and the hole that cooperates with axle.Fig. 8, Fig. 9 are side view and the sectional drawings that the cylindric rolling head 9 of top illustrated rolling running roller 10 is installed.Several (being 5 on the figure) rolling running rollers 10 11 are fixed on suitable separately position ordinatedly with separately axle separately among the figure.Each 11 shaft core line Y round rolling head 9 length directions is distributed in shaft core line Y with this rolling head 9 and is on the periphery of round a at center, by rolling head bottom 9 ' on axially extending bore 17 be connected with rolling head 9.There is groove 12 axle two ends of 11, after it inserts through hole 17, collar 14 are snapped in the groove, make axle 11 be fixed in the axis X direction.On the other hand, rolling head-shield 15 is housed, on rolling head-shield 15, has the through hole 17 that equates with the quantity of axle 11 ' and in order to allow the hole of being passed through by the pipe 30 (Figure 10) of processing and forming 19 at the peristome of rolling head 9.With from rolling head bottom 9 ' end of going up outstanding axle 11 is the same, also be installed with in end outstanding from rolling head-shield 15 collar 14 '.In this wise, axle 11 and rolling running roller 10 are installed on the rolling head 9 pivotally.Figure 10 is a side view of roughly representing to have the taper thread rolling mechanism 20 of rolling head 9, on the figure, is connecting the motor 13 that rotary motive power is provided to the rolling head 9 that contains rolling running roller 10.Motor 13 and rolling head 9 are installed on the basic part 23 of this mechanism 20 by motor support platform 21, and can slide in axis Y direction (being length direction) with respect to basic part 23, also promptly, can move on the sliding axle 25 of motor support platform 21 in basic part 23.The pipe 30 of doing moulding processing is by hold assembly 27 clampings that are arranged on the basic part 23.The 29th, the clamping lever of clamping pipe 30 usefulness on the hold assembly 27 is firm with pipe 30 clampings with the way of manually rotation.Needs are done pipe 30 right side from figure of moulding processing and inserted, contact the back with rolling running roller 10 with holding handle 29 stubborn pressures, make the axial line of pipe become coaxial shape to be fixed with the shaft core line Y of motor 13 and rolling head 9 at it by clamping part 27.Rolling running roller 10 as previously mentioned, has the product conical surface part tapering finished than rolling big slightly tapering, the screw thread position of using do extrusion modling 3 (form of thread 5 is omitted among the figure), therefore, the pipe 30 that is inserted into does not need to contact with the intersection point of running roller end face 31 (being the bight) with the periphery at extrusion modling screw thread position 3, as long as and leave on the periphery at screw thread position 3.After pipe 30 is fixed, but the operator makes rolling head 9 revolutions with regard to starter 13.Along with the revolution of rolling head 9, be contained on the rolling head 9 can be rotating each 11 be center steering (revolution) also with axis Y, simultaneously, axle 11 and the rolling running roller 10 that is contained on the axle 11 also are center steering (rotation) with the axis X.On each rolling running roller 10 just like the preceding described form of thread 5 (Fig. 7), by carve screw thread 33 in the end of pipe 30 gradually.Because pipe 30 and can not be moved on axis Y by hold assembly 27 clampings, so carving along with continuous screw thread 33, rolling head 9 and motor 13 and motor support platform 21 just in the figure right side automatically move, the screw thread that shuts out desirable tapering is also carved by the guiding of the roll forming threaded portion 1 of rolling running roller 10 soon in the end 35 of pipe 30.Like this, when the end 35 of pipe 30 arrives the end face 34 of threaded portion 1 of rolling running rollers 10, motor 13 is stopped operating, continuous taper thread rolling process promptly comes to an end.In addition, when the pipe 30 after the rolling end is withdrawed from, can make motor 13 reversed turnings from this mechanism 20, the rolling head 9 just left side in figure moves, and the meshing relation of screw thread promptly is disengaged.Certainly, also having a way is exactly after the clamping of hold assembly 27 is unclamped, with manual revolution pipe 30 and with it taking-up.The rolling head 9 of adorning rolling running roller 10 being moved towards pipe 30, replace motor 13 is fixed on the basic part 23, also is feasible towards the left of rolling head 9 to mobile such mechanism and make hold assembly 27 and holding handle 29.In addition, rolling running roller 10 is not fixed on the axle 11 on and make it and can slide, along with rolling the quarter of screw thread, each rolling running roller 10 left direction in figure voluntarily moves also be fine (motor, hold assembly are fixed).Yet, in said mechanism, when being provided with as tubing, for make tubing on the periphery that touches the extrusion modling threaded portion after feeding automatically, a lead angle must be set on the rolling running roller.That is, be necessary to process threaded portion 1,3 with desired lead angle.In fact, the processing of rolling running roller is very bothersome, and, in case after the processing, it is impossible wanting to adjust lead angle.
Summary of the invention
The purpose of this utility model is no longer need on rolling running roller body lead angle be set, but the tubing processing taper thread rolling mill of in the installation configuration of rolling running roller, thinking hard.
In order to reach above-mentioned purpose, the utility model provides such tubing processing to use the taper thread rolling mill: it has a rolling head, has several rollings to be centered around rolling head axis circumferencial direction with running roller and the pitch of the defined that staggers on axis direction distribution installation.These rollings have the circular conical surface part that equates with desirable taper angle separately with running roller.Their (rolling running rollers) are made up of two positions: one is to become skewed installation with the angle of inclination corresponding to desirable screw thread effective diameter place lead angle with the tubing axis, the band ditch position of using as roll forming; Another faces with band ditch position mutually with this roll forming, and is bigger slightly than the tapering of above-mentioned conical surface part, the taper band ditch position of using do extrusion modling.
Use the utility model,, therefore, no longer need to process screw thread as before with lead angle as long as on rolling running roller body, process single groove (be not helix groove but one by one independence and discontinuous peripheral groove).Replace rolling running roller pitch with defined on axis direction is staggered, and become an inclination angle that is equivalent to lead angle to come skewed installation with tube axis with one, like this, the groove that is rolled into by each rolling running roller has formed one just like the continuous spiral grooves that forms along lead angle from axis direction.Its result, in a single day processed pipe is cut, will automatically send into to the inboard with the effect of a lead angle.Like this, the processing of extruding on pipe and screw thread is just carried out simultaneously.

The specific embodiment
Below, embodiment of the present utility model is described.Fig. 4 represents the legend of rolling running roller 100 with respect to the configuration relation of pipe 30 conceptually.Each rolling running roller 100 has the 10 same extrusion modlings of rolling running roller trench portions 103 and the roll forming trench portions of representing with Fig. 7 101.The rolling running roller 10 that these extrusion modlings are represented with key elements such as the diameter of trench portions 101 and Fig. 7 with trench portions 103 and roll forming basic identical, different is, on the periphery of rolling running roller 100, form, as previously mentioned, not screw thread, but independent and discontinuous peripheral groove this point.
Several same rolling running roller 100 is shown in Fig. 6 expanded view, and on the axis X direction, they line up zigzag shape with the pitch a of defined with staggering.Promptly, in Fig. 6, rolling running roller 100 be according to 1. → 2. → 3. → 4. → 5. → such order, stagger with pitch a singly, and 1. → 2. → 3. → 4. → 5. → in fact as shown in Figure 4 this (only represented 3 rolling running rollers) among the figure, is arranged in zigzag shape.Its result, pipe 30 is along with the feeding of axis direction, according to 1. → 2. → 3. → 4. → 5. → such order contacts with rolling running roller 100, its end promptly has been implemented extruding, taper thread processing (rolling).
Each rolling running roller 100 is shown in Fig. 5 expanded view, by what be installed with obliquely with a predetermined angular α who is equivalent to lead angle with respect to axis X.For example, the back shaft 111 of each rolling running roller 100 is installed obliquely with respect to rolling head 9 got final product.With aforesaid structure, even also can not obtain lead angle effect of equal value at the rolling running roller from processing lead angle on one's body, therefore, pipe 30 is in case had by first or second rolling running roller, thereafter, just by helical pitch automatically with tube feed.In addition, processing sequence, method etc. are identical with the former technology shown in the figure below Fig. 7.
An embodiment of Fig. 1～Fig. 3 squeezing thread processing machine that to be expression install in the device to be constituted with Fig. 4～rolling roller set shown in Figure 6.Basic structure is with shown in Figure 10 identical, and therefore explanation is omitted.Shown in Fig. 1 showed, on the axis X direction, rolling running roller 100 was staggeredly arranged with pitch a.And the back shaft 111 of rolling running roller 100 is that angle [alpha] with defined is installed with obliquely with respect to rolling head as mentioned above, and the angle [alpha] on Fig. 4, Fig. 5 is represented turgidly, in fact, is a very little angle (for example, about 1 °).
On the squeezing thread processing machine of Fig. 1～shown in Figure 3,, on rolling head 9 (rolling head bottom 9 '), install a centering utensil 120 in order to obtain the circularity of processed pipe 30 (circularity of periphery) preferably.Centering utensil 120 has used the principle of pencil-sharpening device basically, has the body 123 of coniform tapered opening 121 (but the tapering of representing figure on is very little, looks like an individual cylindrical hole) can dismantle by installation shaft 125 and is mounted freely on the rolling head 9.
As Fig. 2, shown in Figure 3, on body 123, burying a cutting head (sword) 137 of charging in its opening 121 underground.Its diametric amount of charging into can be regulated with adjusting bolt 127.For this reason, on cutting head 137, to make one and can insert the slotted hole 129 of adjusting bolt 127.Pipe 30 is inserted in the opening 121, pipe 30 or centering utensil 120 are turned round relatively, the periphery of pipe 30 just equally is cut just like the main points of pencil-sharpening device, and, in the feeding process of axis direction, with its face that is cut serves as guiding further deeply, be cut the outer peripheral face that obtains just become with the axle center of pipe irrelevant justify (proper circle) in fact completely.In addition, the 131st, the block of the insertion position of control pipe 30.
During thread rolling, in order to carry out high-precision processing, the circularity of guaranteeing the pipe periphery is precondition, and therefore, it is exceedingly useful that aforesaid centering utensil 120 is provided on the loom integratedly.
The utility model has not only been made the helical pitch screw thread at the rolling running roller on body, and, like words of in configuration, thinking hard as described above more, two procedures originally (extrusion process and thread rolling operation) has just become a procedure, manufacturing time shortens, and since rolling mill structure itself simply, miniaturization makes to move at engineering site and become easily.In addition, rolling running roller manufacturing itself is also easy, cheap.
