Abstract
The present invention relates to a device for pressing a corrugation on a metal smooth pipe (1), wherein the corrugation extends horizontally to a longitudinal direction of the pipe and has a peak and a trough extending along a circumferential direction of the pipe. The device has a corrugation unit (2) that is rotated in a working position along a circumferential direction for forming a projection. A guide bush (5) for guiding the movement of a smooth pipe (1) in a longitudinal direction is arranged in front of the corrugation unit (2). A supporting sleeve (7) is directly arranged behind the corrugation unit (2), and tightly surrounds a corrugated pipe (6) deviating from the corrugated unit (2) along a traction direction without affecting the movement of the corrugated pipe (6) in the longitudinal direction.
Description
Technical field
The present invention relates to a kind of equipment for corrugating on the smooth pipe of metal system, described ripple is transverse to the extending longitudinally of described pipe and have along crest and the trough of the circumferential extension of described pipe, described equipment has bellow means processed, described bellow means processed have in operating position along circumferential hoop around, for generation of the projection of ripple, and wherein, the pilot sleeve (EP1084774B1) for guiding the smooth pipe vertically moving along it is installed before described bellow means processed.
Background technology
This equipment is used to manufacture metal tubing that can be better bending, the pipe with good flexibility of being for example made up of steel, copper or aluminium.This pipe for example can be for the manufacture of cable or optical cable or as the electric conductor of high frequency cable or for transport flow medium.Ripple can be designed to spirality or annular.Flexible degree depends primarily on the degree of depth of ripple, depends on the radial difference between crest and trough.
According in the known equipment of aforesaid EP1084774B1, pipe is made up of metal tape extending longitudinally, and it is welded on a longitudinal seam.Afterwards, the smooth pipe obtaining thus is longitudinally made into ripple transverse to pipe in bellow means processed.Be equipped with ripple disk processed bellow means processed before, be directly mounted with the pilot sleeve that is called corrugated sleeve processed, the internal diameter of this pilot sleeve is substantially equal to the external diameter of smooth pipe.From bellow means processed bellows out through one hollow shaft that be connected with bellow means processed, elongation, this hollow shaft is connected with motor.Hollow shaft holds bellows with a determining deviation.
Summary of the invention
Technical problem to be solved by this invention is, so designs aforementioned device, and the size that makes bellows especially also can obtain higher form accuracy or circularity in the case of having relatively dark ripple.
Described technical problem is by being solved according to equipment of the present invention, wherein after bellow means processed, be directly mounted with bearing sleeve, described bearing sleeve is closely holding the bellows leaving along lead from bellow means processed, but does not hinder this bellows along its longitudinal movement.
Be placed in bellow means processed bearing sleeve below and can keep in the axial direction shorter size, this bearing sleeve is for pipe provides a kind of fixing point in ripple process processed, and in this process, pipe radially bears huge load.Bearing sleeve guarantees that pipe is manufacturing in ripple process but radially can not depart from desired center after especially leaving bellow means processed.Thus, leave bellow means processed and the pipe that moves along lead has uniformly in its whole length or the ripple remaining unchanged and size uniformly same or that remain unchanged.Because pipe is guided very exactly by bearing sleeve among ripple processed or afterwards, thus can especially advantageously manufacture ripple to the pipe of thin-walled, and also can manufacture darker ripple, this pipe for high bendability is significant.The bearing sleeve being close on bellows also has other advantages, is placed in bellow means processed pilot sleeve before and needn't be close on smooth pipe, but completely also can have the internal diameter larger than the external diameter of smooth pipe as pure guiding parts.
Accompanying drawing explanation
Embodiments of the invention shown in the drawings.In the accompanying drawings:
Fig. 1 illustrates the schematic diagram for the manufacture of the device of bellows,
Fig. 2 is illustrated according to spendable according to the enlarged drawing of equipment of the present invention in the device of Fig. 1.
The specific embodiment
By according to the device of Fig. 1, can on the smooth pipe 1 being made of metal, arrange transverse to its wave-like extending longitudinally.It is unimportant at this that method produces pipe 1 in which way.Pipe for example can be made up of steel or copper or aluminium.Can be annular or spiral at the ripple of bellow means 2 interior generations processed.
Pipe 1 for example moves along direction shown in arrow 4 by the draw-gear 3 only schematically showing, and is pushed through in the embodiment shown thus bellow means 2 processed.Observe along lead, before bellow means 2 processed, settle pilot sleeve 5, smooth pipe 1 is guided through pilot sleeve 5.Be conducted through along lead pipe that is shaped with ripple 6 out from bellow means 2 processed the bearing sleeve 7 being directly placed in after bellow means 2 processed.Bellows 6 can be wrapped on spool 8.
Equipment according to the present invention elaborates below in conjunction with accompanying drawing 2:
The bellow means processed 2 using in this equipment is known substantially.Therefore only to setting forth in order to understand part required for the present invention.Bellow means 2 processed comprises ripple processed termination 9, and it is designed to have the annular ring of medium pore.Ripple disk 10 processed is for example rotatably placed in medium pore by ball bearing 11.Ripple disk 10 processed has radial finger projection 12 to the inside, and in the time that equipment moves, ripple is pressed in smooth pipe 1 by projection 12.
Ripple disk 10 processed is settled with respect to the axis A of pipe 1 or bellows 6 prejudicially according to Fig. 2.Therefore the axis of ripple disk 10 processed and pipe 1 or 6 extends in parallel spaced reciprocally.In the time that equipment moves, ripple processed termination 9 and by the ripple disk 10 processed of its drive along the circumferential rotation around pipe 1.At this, the projection 12 of ripple disk 10 processed is pressed into ripple in pipe 1, and pipe 1 moves through bellow means 2 processed along the direction of arrow 4 simultaneously.
Bearing sleeve 7 direct neighbors ground or along lead be placed in bellow means 2 processed after, and with the axle A of pipe 1 or 6 be concentric.Bearing sleeve 7 for example also can be connected with ripple processed termination 9, and or be fixedly connected with, bearing sleeve 7 is rotated together with ripple processed termination 9, or connect rotationally by bearing, bearing sleeve 7 is not rotated with ripple processed termination 9.But bearing sleeve 7 also can not be fixed on ripple processed termination 9.Bearing sleeve 7 for example can be made by plastics, as polyethylene or polyamide, or makes by metal, as bell metal.
Bearing sleeve 7 as far as possible closely surrounds bellows 6, but can, closely to reclining with bellows, not cause hindering bellows 6 along its longitudinal movement.Bearing sleeve 7 is a kind of fixing point for bellows 6 in ripple process processed, because bellows 6 is maintained at center by bearing sleeve 7 during ripple processed and afterwards.Due to this function of bearing sleeve 7, make pilot sleeve 5 no longer need to be close on smooth pipe 1.Figure 2 illustrates the gap between pipe 1 and pilot sleeve 5.Pilot sleeve 5 does not together rotate with bellow means 2 processed.Pilot sleeve 5 is correspondingly supported with respect to bellow means 2 processed by gantry post 13.
Bearing sleeve 7 is advantageously designed to relatively short vertically.Bearing sleeve 7 for example can have the width that is about as much as two peak-to-peak distances of continuous wave when annular corrugated, or in the time of helical fissure, is about as much as the width of twice pitch.
