Abstract
The invention relates to a method and an apparatus for bending the rims of a hole for a hole-enclosing collar or neck. The collar is produced by means of a forming die (3) adapted for substantially radial movement from inside the pipe outwards. A calibration mandrel (11) is pressed by means of an external drive unit from outside inwards into a collar established by the forming die (3). The calibration mandrel stretches the collar to match its own size and rectifies the undersized transverse dimension and the oversized lengthwise dimension of the forming die. Upon its penetration into the collar, the calibration mandrel (11) pushes the forming die (3) back to its initial position for a new collaring operation.
Description
Technical field
The present invention relates to a kind of equipment of limiting in the preamble of a kind of method that in the preamble of claim 1, limits and claim 3, be used on pipeline, making bypass collar extension or eck.
Background technology
This method and apparatus can be from the early stage patent publications US5 of the applicant, learns in advance in 515,710.
When a tubular metal case or sleeve, by stretching case material, form a bypass, when cylinder collar extension or the structure of eck, its final size is by the elasticity of pipeline and the residual stress decision of material internal.Usually, the dimension D of collar extension on the cross-section of pipeline direction
2Than dimension D longitudinally
1Little.And at most associated materials, such as under stainless situation, collar extension size in the horizontal is less than the dimension D of the instrument that is used to form collar extension
2'.
At existing patent publications US5, in 515,710,, solved this problem by providing the mould of its diameter greater than pipe diameter.By the pipeline extruding is become ellipse, this large-sized shaping dies is transmitted in pipeline, thereby the diameter of pipeline increase on the large scale direction of shaping dies.This set is applicable to have the thin pipeline of desired flexible large-scale and wall.For less pipeline, wherein, the ratio of diameter and pipe thickness has changed the elasticity of pipeline, makes the ovality of described elasticity and pipeline not play effect, and the shape of eck or collar extension and size can having thus described the inventionly realize.
Summary of the invention
The object of the present invention is to provide a kind ofly to can be used to revise by at patent publications US5, the collar extension of announcing in 515,710 is offered eck or the circularity of collar extension and the method and apparatus of diameter dimension that device forms.
This purpose can be utilized the method described in the appended claim 1 and realize at the device described in the claim 3.Dependent claims discloses preferred implementation of the present invention.
Description of drawings
Now, will be with reference to the accompanying drawings, in the mode of working example the present invention is described in more detail, wherein,
Fig. 1 shows the side view and the vertical view of present device respectively;
Fig. 2 shows the pipeline offered after the collar extension and its collar extension and the forming tool relative size with respect to pipe diameter D in the perspective view mode;
Fig. 3 shows equipment shown in Figure 1 situation when mould is in initial position, except the size of mould, and at patent publications US5, and disclosed device consistent (calibration axle of the present invention does not illustrate) in 515,710;
Fig. 3 A and 3B show mould and it Different Diameter to size;
Fig. 4 shows the cross section that the line IV-IV in Fig. 1 is got; And
Fig. 5 show the calibration axle Different Diameter to size.
The specific embodiment
Embodiment shown in the reference, the body 1 of this equipment comprises a cylindrical elements that has vertical hole of square-section, it cooperates with elongated wedge 2 and its end element 5, and its end 4 can be by a driver element engagement that is used at vertical operation wedge 2 of body 1.
The cylindrical surface of body 1 has hole or the groove 9 that is substantially radially.This hole or groove 9 also can be configured to the desirable angle of central axis scope between 90 to 45 degree with respect to body 1.Yet the most common pipeline bypass pipe is quadrature and the most common collar extension or eck are quadratures, thereby this angle is 90 degree.When shaping mould tool 3 was placed in hole or the groove 9, the bottom of mould 3 contacted with the wedge-like surface 14 of wedge 2.In described example, operate by drawing wedge 2, but it also can be by advancing line operate.Also can consider the wedge that adopts two can in the opposite direction move.
The pipeline that will be offered collar extension is pulled on the body 1, thereby above one on this pipeline hole that is shaped in advance is arranged on hole or groove 9, and aim at it, and mould 3 is arranged in hole or the groove 9.When wedge 2 by big or thicker end is when mould 3 moves with it by force, described mould 3 is upwards driven, with force duct wall around the preformed hole outwards.Duct wall stretches around the edge in preformed hole, and forms the eck or the collar extension of bypass, and its shape and direction are consistent with the mould 3 of demonstration.
In order to reach comparatively loose cooperation in pipeline, the tool diameter shown in the design drawing 3 is to avoid the staying friction vestige on the inwall of pipeline.The mould 3 that cooperates in hole or groove 9 cannot have the size that can cause vestige on inner-walls of duct.When its size of manufacturing equaled the by-pass prot of pipeline itself, this caused that about mould the problem of vestige or scratch is especially obvious.
Adopt method and apparatus of the present invention to make this problem obtain solution, wherein make it to be ellipse by design collar extension mould 3, thus it with the diameter D of pipeline crosscut
2' less than the inside diameter of pipeline and less than the diameter D of mould 3 on pipeline is vertical
1'.
The eck or the collar extension that adopt above-described mould 3 to produce are oval or circular.Collar extension diameter D
2Less than the dimension D that depends on mould 3
2' interior conduit diameter D, also less than the diameter D of inside moulding stress that depends on material and flexible mould 3
2'.
The ellipse of collar extension can adopt the special calibration axle 11 that is used to finish collar extension to adjust.11 designs of calibration axle are used for offering the equidirectional earth's axis of center line in the hole 9 in the instrument to moving along appearing at collar extension, and it can be forced into enough big power on the mould 3, the mould 3 that is used for promoting in its front returns in the hole 9 it, and collar extension is stretched over its size.
The diameter D of calibration axle 11
3(laterally) and D
4(vertically), and the D of mould 3
1' (vertically) and D
2' (laterally) be to be mutually related, and depends on the size of the pipeline of being processed and quality (elasticity) and the end product of wishing, especially whether wishes the inside diameter D of collar extension
2Consistent with the internal pipeline diameter, or the outer dia of not wishing collar extension and pipeline equates.If outer dia equates, determine mould 3 vertical diameter D so
1' be D so that diameter to be provided
1Collar extension, it is big to making the corresponding outer dia of collar extension show slightly excessive.In this case, the trans D D that is designed and sized to it of calibration axle 11
3The edge of collar extension is stretched, make its size and external pipe diameter be complementary, and its vertical diameter D
4At vertical D
1On supporting collar extension, make to reduce a large-sized scope that produces by mould 3 with its diameter in the same way.In calibration process, occur in and diameter D
1' the reducing of size on equidirectional, in fact help trans D D
2Lateral extension.
So calibration axle 11 has double action.It promotes the bottom that mould 3 returns to hole or groove 9, and the dimensional discrepancy of the inconsistent adjustment mould 3 of its breadth wise dimension of while, this dimensional discrepancy can not be caused in the true institute that laterally produces enough big diameter dimension by the mould that is matched with pipe interior.
