Abstract
A both manual and electric non-cutting threader for taper pipe is composed of a locking screw rod, a screw rod for fixing iron tube, big gear, roller and its holder, and small straight gear. Its advantages are simple structure and small size.
Description
The present invention relates to an a kind of metal tube processing taper pipe thread silk machine, especially do not have the machining taper pipe thread.
At present, known metal tube processing taper pipe thread like this, is not only lost time all with screw die or machined into, the waste metal, and also make the tube wall attenuation after the cutting, increase wall thickness man-hour so have to make metal tube to add, with the intensity after the assurance cutting.
The purpose of this invention is to provide a kind of hand, metal tube taper pipe thread machine that electric dual-purpose does not have cutting.
The object of the present invention is achieved like this: the locking screw mandrel, fixing iron pipe screw mandrel, gear wheel, roller, rolling wheel support, small Spur gear assembles and forms, after the metal tube processed inserts fixedly the iron pipe screw mandrel, allow the locking screw mandrel shorten downwards by nut, spreading is resilient several valvulas in iron pipe screw mandrel top fixedly, until allowing circle in the valvula tensioner processing metal pipe, afterwards, shake handle, allow spur gear drive gear wheel, by the pitch rotation on the fixing iron pipe screw mandrel upwards, be fixed on roller on the gear wheel and rolling wheel support and also rotate and make progress, on metal tube, roll out with the fixing screw thread of the same pitch of screw mandrel by several rollers, also be rolled into the taper button so roller is a taper metal tube head.Afterwards gear wheel is return original position.Unclamping mother sieve promptly machines.Spur gear can be by hand and driven by motor, and this figure does not draw the motor part.
Owing to adopt such scheme, can change smithcraft with machining.These facility have the little characteristics of volume simple in structure.
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structure external form figure of invention.
Fig. 2 is the cutaway view of Fig. 1.
Among the figure: (1) gear wheel (2) turning rolls
(3) the fixing iron pipe screw mandrel of roller (4)
(5) locking screw mandrel (6) work metal pipe
(7) spur gear (8) handle
(9) nut
In the drawings, after circle in the work metal pipe (6) inserts fixedly iron pipe screw mandrel (4), by nut (9) allow locking screw mandrel (5) the valvula tensioner on fixing iron pipe screw mandrel (4) top on inner wall of metal tube, shaking handle (8) afterwards makes spur gear (7) drive gear wheel (1) rotation upwards, until the button on the metal tube (6) is rolled into size, afterwards, gear wheel (1) is returned to original position, unclamp nut (9) and withdraw from metal tube, machine.The interior garden of gear wheel (1) and fixedly the pitch of iron pipe screw mandrel (4) equal work metal pipe pitch, the tapering of roller (3) equals work metal pipe tapering, in addition, not screw buckle on the roller (3) but be processed into a plurality of ditch ridges that the section of each ditch ridge is identical with work metal gas thread section.And the ditch ridge of several rollers is not in one plane, but spends divided by 360 with work metal pipe pitch, multiply by two adjacent rollers circumference differential seat angles.Differential seat angle as two rollers among the figure is 180 degree, the ditch ridge phase difference of half processed pipe pitch of two rollers so.
Claims (4)
1. hand, electronic no cutting cone pipe thread cutting machine, by the locking screw mandrel, fixedly iron pipe screw mandrel, gear wheel, turning rolls, roller, small Spur gear assemble and form, it is characterized in that: after circle in the work metal pipe inserts fixedly iron pipe screw mandrel top, by nut allow the locking screw mandrel fixing several valvula tensioners of iron pipe screw mandrel top on metal inner surface, shake handle afterwards and rotate up at the drive gear wheel, until metal tube is rolled into requirement by spur gear.
2. taper pipe thread machine according to claim 1 is characterized in that: the pitch of locking screw mandrel and gear wheel endoporus is identical with processed metal tube pitch.
3. taper pipe thread machine according to claim 1 is characterized in that: the roller tapering is identical with work metal pipe tapering, is not screw buckle on the roller but is processed into a plurality of ditch ridges, and the section of each ditch ridge all equals the section of work metal gas thread.
4. taper pipe thread machine according to claim 1 is characterized in that: the ditch ridge of each roller not in one plane but not multiply by two roller circumference differential seat angles with work metal pipe pitch divided by 360 degree.
