The specific embodiment
Visible whole instrument in Fig. 1-5.First branch 1 with handle portion 2 is used to be gripped by the operator with second branch 3 with handle portion 4.First branch 1 has pneumatic jack 5 in distance operator end farthest, is used for the parts 6 and the building mortion 7 of vice attachment.Second branch 3 has pitman arm 8 and sliding jaw 9 in distance operator end farthest.First 10 in corresponding first installation on building mortion 7 and/or pitman arm 8 with building mortion 7 and pitman arm 8 pivot combinations.Second 11 in corresponding second installation in the pitman arm 8 and/or second branch 3 with pitman arm 8 and the 3 pivot combinations of second branch.Simultaneously, axle 10,11 existence means that first branch 1 pivots to be combined in second branch 3 and can to have branch 1,3 in each hand by the operator and handles (manoeuvred) instrument.
Nature can also be expected replacing is that in the described pipe each only extends through the part of corresponding handle portion 2,4 or do not extend through corresponding handle portion 2,4.Two pipes can also length different and form by elastomer or another suitable material separately accordingly handle portion extend through different distance, make branch 1,3 equal in length basically.
On first handle part 2, there is the transportation locking device 2a of the strips that constitutes at least one ring, referring to Fig. 5.If ring is threaded on the second handle part 4, then handle portion 2,4 also has branch 1,3 to keep together very reliably in the instrument transportation thus.The band of transportation locking device can be out of shape with bending and by elastic fabric, rubber or similar material to be made.
Especially referring to Fig. 3 and 4, pneumatic jack 5 has crooked hook-type, thus can be when bending operation holding tube 12.Utilize with (promptly in this crooked principle equivalent in meaning
And bockning) and by means of operation, obtains bend pipe.The parts 6 that are used for vice attachment are outstanding and have two plane-parallel substantially side planes 13,14 that are suitable for vice attachment from instrument.
Building mortion 7 has the cylinder segment shape that changes shape, and its circumference has and is used to hold the described groove 15 for the treatment of bend pipe 12.Groove 15 extends on the plane in the substance of described improvement cylinder segment and extends the paper plane of described extension plane parallel in Fig. 2 and 5-7 along semicircle on described circumference next door at least.Described semicircle have and the center of the bottom of groove 15 and axle 10 between corresponding to first radius of vertical range, this first radius should be selected according to the size for the treatment of crooked pipe 12, pipe for size 12, the chosen 37-47mm that is roughly of described radius, preferably be roughly 42mm, for the pipe of size 15, the chosen 50-60mm that is roughly of described radius preferably is roughly 55mm.As the universal experience rule of the broad sense relevant with above-mentioned size, proposing described first radius should be less than maybe equaling to manage four times of 12 diameter.Described first radius directly is equivalent to manage 12 final bending radius.
In addition, groove 15 has semicircular basically shape on the cross section vertical with its most of development length, and it has should consistent with pipe 12 cross section radius and thus also should be according to the second selected radius of the size for the treatment of crooked pipe 12.Whole building mortion 7 is easy to change on instrument, therefore has the building mortion that suitable existing radius measures and can be used to pipe size that each exists usually.Building mortion 7 is assemblied in the branch 1 by the screw in the branch 1, pin, and simultaneously the building mortion 7 when preventing tool using of the respective aperture on screw and the pin coupling building mortion 7 rotates around screw.Described layout only is an example and can realizes function corresponding by any other mode.
The web part of building mortion 7 just groove 15 and the part between first 10 is compared thinly with peripheral part, can disconnect the through hole 16 that a plurality of changes shapes are arranged in addition.In addition, building mortion 7 has from 0 ° of-180 ° of angle index rule 17, and 0,45,90,135 and 180 angle value especially by such mode by marking, promptly not only exist and be used for the graduation mark of described angle value, and use the digital writing angle value.The surface of graduation mark and the recessed rule 17 of numeral also utilizes color to carry out marking to be different from the remainder on surface.In addition, there are pipe location scale 18 and pipe location scale 19, they are located along extending initial imaginary, the straight basically line of energy portion from the imagination of 0 ° of marking on the rule 17, pipe location scale 18 is than 0 ° of marking on the scale 19 more close rules 17 of pipe location, and described line is arranged essentially parallel to accurately to be arranged on the instrument and extends with each pipe fitting 12 that is bent.Building mortion 7 also has five specific overbending scales 20.In addition, can on building mortion 7, exist auxiliary handle part/thumb grip to divide (not shown).
Sliding jaw 9 is connected in second branch 3 by two pin 21 (for example tension pin 21) of suitable type.Sliding jaw 9 is made by polymeric material or similar material and is had start index 22 and two pipe location scales 23,24.Simultaneously sliding jaw 9 has and is used to hold the described groove 25 for the treatment of crooked pipe 12.Groove 25 extends and have a semicircular basically shape on the cross section perpendicular to its most of development length along the whole length of sliding jaw 9, and this shape has should consistent with the cross section radius of pipe 12 and thus also should be according to the 3rd selected radius of the size for the treatment of crooked pipe 12.It can also be the semicircular in shape that changes shape.Sliding jaw 9 also is easy to change on instrument, therefore has the sliding jaw that suitable existing radius measures and can be used to pipe size that each exists usually.
The end of pneumatic jack 5, the parts 6 that are used for vice attachment, pitman arm 8 and second branch, 3 the most close axles 11 is made by forged steel or similar material.Axle 10,11 is made by steel or similar material and building mortion 7 is made by aluminium or similar material.The material of mentioning in this article is counted as example without any exception.Thereby, except steel, branch 1,3 can be made by multiple alternative known materials, for example other metals, light metal, synthetic and/or plastics, and these materials can be applied to pneumatic jack 5 equally, be used for parts 6, pitman arm 8 and the axle 10,11 of vice attachment.Correspondingly, except aluminium, building mortion 7 can be made by multiple alternative known materials, for example other light metals, metal, synthetic and/or plastics.Except polymeric material, sliding jaw 9 can be made by multiple alternative known materials, for example steel, pottery and/or synthetic.
Now, will briefly describe how pipe/pipe fitting to be carried out bending by instrument according to the present invention.At first, each building mortion 7 that exists on operator's checking tool and the sliding jaw 9 that exists on instrument equally have the size that is suitable for the described pipe 12 that will relate to, and just described first, second and the 3rd radius are correct according to the pipe size of pipe 12.Then, the operator opens instrument and they is separated from each other by gripping handle part 2,4.Suitably for having pipe fitting 12 forms of the flexural measurement scale (index of bending measure) that is used for the canal curvature that will produce, described pipe 12 is arranged on the instrument to manage 12 modes that drop in the hook shaped ends that is positioned at pneumatic jack 5 in the groove 15 simultaneously pipe 12.For the canal curvature that will produce and for roughly 90 ° bending, described flexural measurement constitutes the distance of the perpendicular between the plane of managing 12 end and managing central lines straight basically in 12 firsts basically together, the substantive bearing of trend that described plane is substantially perpendicular to the second portion of pipe 12 simultaneously extends, and described first and second parts of pipe 12 are formed in each the straight branch that comprises on the canal curvature.For the expression on " plane that overlaps basically with straight basically center line ", mean and center line intersects plane simultaneously in parallel basically that at this just center line is arranged in this plane.For the expression of " center line ", this mean with pipe each cross section of 12 on the crossing line in round center.If it is initial that described flexural measurement is given as from the left side of pipe fitting 12, then when operator's gripping firmly essentially horizontally was positioned at the pipe fitting 12 of its front, it is just in time relative with the described pipe location scale 19 of building mortion 7 that described flexural measurement scale is arranged to.Yet initial if described flexural measurement is given as from the right side of pipe fitting 12, it is just in time relative with the described pipe location scale 18 of building mortion 7 that described flexural measurement scale is arranged to.
The operator lumps together branch 1,3 subsequently lightly, and whole length abuts against on the pipe 12 along it until sliding jaw 9, and it is positioned at also filling groove 25 fully or at least farthest of groove 25 thus.What usually be suitable for is, pipe 12 connects stable more in groove 12,25, and the possibility that the distortion that do not meet the requirements take place when bending pipe 12 is more little.The operator checks that the start index 17a that is used for 0 ° on the rule 17 of start index 22 and building mortion 7 on the sliding jaw 9 is just in time relative.For similar reason, what satisfy subsequently is that pipe location scale 23 on the sliding jaw 9 is just in time relative with pipe location scale 18 on the building mortion 7, and the location of the pipe on the sliding jaw 9 scale 24 and the pipe on the building mortion 7 to locate scale 19 just in time relative.The instrument that the operator allows to have pipe fitting at this moment is in the crooked preceding position that can see among Fig. 6.After this, realize the accurate bending of pipe 12, the operator lumps together branch 1,3 with the bigger power of continuous motion utilization, and sliding jaw 9 slides on pipe 12 and makes it press building mortion 7, until obtaining required angle of bend.In each moment, by the given angle of bend that obtains of angle value marking on the 22 residing rules 17 of the start index on the sliding jaw 9.Yet, often must allow tube material generation elastic after effect to a certain degree, this means form overbending, just than the bigger bending of required angle of bend accurately, with the required angle of bend of real acquisition.At this, overbending scale 20 is useful, and to 90 ° of bendings, it marks 3 ° of overbendings, 6 °, 9 °, 12 ° and 15 ° respectively.Thereby, if the operator understands the material and the attribute thereof of pipe 12 very much when bending, for example know that overbending reaches 93 ° of final bendings that can obtain 90 °, then he continues branch 1,3 lump together, and reach itself and the just in time relative position of the first overbending scale 20 of 90 ° of scales counting from rule 17 until the start index on the sliding jaw 9 22.In Fig. 7, show and be overbending to 96 °.After finishing bending, the operator opens instrument by handle portion 2,4 is separated from each other, and final subsequently canal curvature can be raised out.
Certainly make the overbending scale at other angle value that becomes on the rule 17 outside this provides, for example on 45 ° of bendings that are used to produce angle of bend or what its angle value in office, become about 3 ° and/or about 6 ° and/or about 9 ° and/or about 12 ° and/or about 15 ° with this size.Described angle value is preferred, but also can with about 1 °-3 ° and/or about 4 °-6 ° and/or about 7 °-9 ° and/or 10 °-12 ° and/or 13 °-15 ° interval the overbending scale be set on 45 ° or on what its angle value in office.
Especially show following advantage according to instrument of the present invention.Handle portion 2,4 have embossing and be made with major diameter and curved shape so that good gripping to be provided to the operator.Branch 1,3 is longer than in the past, and making need be than littler in the past power when bending.Initial sum pipe location scale that exists on building mortion 7 and the sliding jaw 9 and the big opening between building mortion 7 and the pneumatic jack 5 make and can be easy to and will treat that crooked pipe 12 is arranged in the tram fast.Because sliding jaw 9 is polymeric materials, therefore manages 12 and when bending, can not be scratched.Rule 17 is easy to read, because marking is made, dug the very clear of system and have the color that departs from numeral, same initial, the pipe that is applied to exist on building mortion 7 and the sliding jaw 9 of this point located and the overbending scale.The particular component 6 that is used for the vice connection realizes simple the installation by this way.Specific transportation locking device 2a is convenient to the transportation of instrument and is deposited.
The present invention is not limited to embodiment shown here, but can change in the scope of accessory claim.
