Description

A kind of non-ferrous metal pipe channelling machine

Technical field

The present invention relates to machinery manufacturing technology field, particularly a kind of non-ferrous metal pipe channelling machine.

Background technology

Metal pipe material is owing to having higher pressure high-temp resistant and the characteristic such as durable in use, thereby, oftenFor fluid (comprising gas and the liquid) transfer unit of various kinds of equipment. Due to the spy of various kinds of equipmentDifferent property often need to process difform spill annular groove on tubing. In prior art, metalThe annular groove processing of pipe, roughly has two kinds of modes, and the one, use with the roller of fin and directly rotatingSlot rolling on tubing; The 2nd, pipe two ends are withstood, then, then use with the roller of fin and directly turningSlot rolling on moving tubing. Although these two kinds of modes can process required annular groove,, due to circlePipe (particularly thin-wall circular tube) can produce distortion in the time of slot rolling, causes the precision of processed annular groove inadequateHeight, even can make the circularity distortion of pipe larger.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of easy to operate, can machining accuracy higherAnnular groove and the distortion of pipe circularity be less, for processing the slot rolling device of non-ferrous metal tube.

The technical solution used in the present invention is a kind of non-ferrous metal pipe channelling machine of invention: comprise controlCase 3 and frame 2, control cabinet 3 is arranged on the top of frame 2; Also include pressing wheel device, powerDevice and positioner;

Detailed description of the invention

Below in conjunction with drawings and Examples, the present invention is further illustrated. Explanation is below to adoptBy the mode exemplifying, but protection scope of the present invention should not be limited to this.

The present embodiment is by control cabinet 3, frame 2, pressing wheel device, power set and positioner structureBecome, control cabinet 3 is arranged on the upper left quarter of frame 2.

Control cabinet 3 includes the time relay, power switch and prime mover starting drive, also leads toFloor push 1, convenient operation.

Pressing wheel device is by pinch roller cylinder (can adopt pneumatic cylinder, also can adopt hydraulic pressure side cylinder) 9, twoFront pillar 6, two rear pillars 23, pinch roller guide block 8, indent piece 10 and symmetries are arranged on indent piece 10Two slot rollings wheel 12 form. Two front pillars 6 and two rear pillars 23 are square and are vertically arranged on machineAbove the middle right part of frame 2, pinch roller cylinder 9 is installed in its upper end. On pinch roller guide block 8, have two circular holes,Be used for being sleeved on two rear pillars 23, the leading flank of pinch roller guide block 8 is connected with indent piece 10. IndentThe cross section of piece 10 is " Π " shape, and the bottom of its both sides end face is installed two slot rolling wheels 12 symmetrically;As required, can take turns on 12 U-shaped fin 21 is set at slot rolling, V-arrangement fin 22 also can be set,U-shaped fin 21 and V-arrangement fin 22 also can be set simultaneously.

Power set are by prime mover (conventionally adopting motor) 4, output chain gear 29, chain 5, defeatedEntering sprocket wheel 7, output gear 30 and input gear 28 forms. Prime mover 4 be arranged on frame 2 inBelow portion, output chain gear 29 is installed on its output shaft, input sprocket 7 is coaxial with output gear 30,Be arranged on above the middle part of frame 2, output gear 30 engages with input gear 28, and chain 5 installs aroundBetween output chain gear 29 and input sprocket 7;

Positioner is by supporting roller component, carriage assembly and core bar module composition; Supporting roller component is by two(surface of this support roller is surrounded by glue conventionally, has both increased frictional force, just for piece support roller plate 25 and two support rollersRotate in band pipe, can prevent from again abrading pipe surface) 14 formations, two blocks of support roller plates 25 1 are lastAfter be arranged on above the middle right part of frame 2 (below pinch roller cylinder 9), two support rollers 14 are pacified symmetricallyFill between two blocks of support roller plates 25, after the axle of one of them support roller 14 is stretched out by support roller plate 25 belowInstall input gear 28 (for by power transmission to support roller 14). Carriage assembly be by carrier bar 20,Carrier frame plate 16 and two bracket wheels 15 form, and carrier bar 20 is two bar structures by movable connectionBecome (extending or shorten, be bolted), be arranged on above frame 2, the front end of support roller plate 25,Its end installation bracket plate 16 is installed with symmetrically two bracket wheels 15 on carrier frame plate 16. Core barAssembly be by core bar 11, two fixed blocks 17, connecting plate 24, connecting rod 26 and core bar cylinders (canAdopt pneumatic cylinder, also can adopt hydraulic pressure side cylinder) 27 formations, on fixed block 17, have two circular holes,Be set on front pillar 6 and rear pillar 23, two 17 of fixed blocks are set in the left and right sidesOn front pillar 6 and rear pillar 23, and form fixing; Connecting plate 24 connects two fixed blocks 17, core barCylinder 27 is connected on connecting plate 24 by connecting rod 26; Core bar 11 is stairstepping, its front end (figureIn 3, be left end) with taper, be convenient to install pipe, the projecting shaft of its other end and core bar cylinder 27Connect.

Before use, first by the gases at high pressure highly pressurised liquid process filter of being sent here by air pump or hydraulic pumpAfter 19 filtrations, then regulate required pressure through pressure valve 18, then connect respectively core bar cylinder 27 and pressWheel cylinder 9. , regulate the time of the time relay set, set slot rolling time and send pipe thereafterTime.

When use, first pipe 13 is passed to the right along bracket wheel 15, enters into on support roller 14,Then pierce into the front end (that is: in Fig. 3 for left end) of core bar 11, located by the step of core bar 11,Now, between the surface of core bar 11 and the internal face of pipe 13, leave certain space, for tolerantThe inner groove forming when slot rolling. Then,, with foot-operated floor push 1 once, prime mover 4 starts, movingPower passes to output gear 30 by output chain gear 29 through chain 5 and input sprocket 7, then warp and outputGear 30 engages input gear 28 and drives support roller 14 to rotate, and then drives the pipe 13 on it to rotate;Meanwhile, pinch roller cylinder 9 starts, the projecting shaft of its lower end promote connected indent piece 10 toLower movement, pinch roller guide block 8 leads along rear pillar 23; When indent piece 10 bottom slot rollings are taken turns on 12When U-shaped fin 21 or V-arrangement fin 22 touch the pipe 13 of rotation, also can rotate thereupon, andMoved down with continuing by pinch roller cylinder 9, thereby, roll extrusion on the outer surface of the pipe 13 rotatingGo out required annular groove; After the time that presses down (that is: slot rolling time) of setting arrives, pinch roller cylinder 9 lower endsProjecting shaft upwards bounce back to origination data with connected indent piece 10; Then, core bar cylinder27 start, and its projecting shaft is promoting core bar 11 together with pipe 13 (that is: in Fig. 3 left) forwardMobile, pipe 13 is sent, core bar cylinder 27 bounces back to origination data with core bar 11 immediately, etc.Treat slot rolling action next time.

The length of holder for regulating hack lever 20, applicable to the slot rolling of the nonferrous metal tube of different length; MoreChange the core bar 11 of different-diameter, can be used for the slot rolling of different tube diameters; Change difform fin,Can roll out difform annular groove.

Non-ferrous metal pipe channelling machine of the present invention, is applicable to different tube diameters, different length and similar shape notThe rolling and processing of the annular groove of shape.
