As previously mentioned, adjustable elbow workpiece is processed to have the straight tube of a plurality of global formation sections at first.When the ell make-up machine after finally processing joint on the elbow workpiece, described elbow workpiece remains straight shape (referring to Fig. 1).Then this elbow workpiece is rotated into the structure with angle, and with the formation " annular " that is bonded together of itself and other ell.This being circular layout is the method for optimizing that many manufacturers transport ell.
As shown in Figure 2, an ell that is bent into 90 degree is made up of 4 sections 12.As previously mentioned, each section 12 must be with respect to about 180 degree of its adjacent segments 12 rotations to be positioned to ell the shape of 90 degree.Other ell can also be to have the still less structure of section, and can produce the different angles of rotation ell, but all representative all be to make adjacent section Rotate 180 degree so that produce ell structure finished or that finish.
Get back to Figure 10, described free-standing ell rotary body 40 also comprises a pair of clamping limb 46 and 48.Each clamping limb 46 and 48 is all supporting many to gripping finger 50, and is oriented to and can optionally rotates around rotating shaft R.In operating process, clamping limb 46 and 48 gripping finger 50 are fixed each section 12 of elbow workpiece selectively, and they are rotated to the position of processing, will be elaborated to this below.Many the present invention is not limited to this to gripping finger 50 although each clamping limb 46/48 of described free-standing ell rotary body 40 has, and in not breaking away from the tangible scope of the present invention, clamping limb 46/48 can support arbitrarily gripping finger, also comprises a pair of certainly.
Therefore the important one side of the present invention is that a pair of gripping finger 50 can make 12 rotations of a section, so that all sections 12 can both rotate simultaneously.Like this, particularly with respect to the section of known before manual rotation elbow workpiece, free-standing ell rotary body 40 of the present invention can reduce the production time effectively.
Further as shown in figure 10, clamping limb 46 and 48 is in the position of " making progress ", and the operator puts into straight elbow workpiece 52 the free-standing ell rotary body 40 along the direction shown in the L substantially from the front.Described straight elbow workpiece 52 preferably is configured to so mode guaranteeing seam 14 upwards, and has the end of fold to be exposed.
In case press start button, straight elbow workpiece 52 will be rotated and is positioned at once more on second obliquity 54 of free-standing ell rotary body 40.Therefore, the longitudinal axis of described straight elbow workpiece 52/54 can be arranged to be basically parallel to the rotating shaft R of clamping limb 46 and 48, and preferred and it is in alignment coaxially.Figure 11 shows the partial cross-section end-view of straight elbow workpiece 52/54, and elbow workpiece shown in it is arranged in the free-standing ell rotary body 40, and the clamping limb 46 of this ell rotary body and 48 and gripping finger 50 all be in the position of " making progress ".
When clamping limb 46 and 48 was rotated down, a cam and roller bearing configuration can make their pivots rotate.When each clamping limb 46 and 48 arrived their " downwards " position, each gripping finger 50 contacted so that each gripping finger 50 is parked on its suitable start position with an adjustable stop part 56, thus clamping section 12.Described stop part 56 is a manual adjustments, so that each section 12 is all produced appropriate rotation amount.
When clamping limb 46 and 48 was positioned at the position of its " downwards ", gripping finger 50 had surrounded each section 12 of ell workpiece 52/54.As shown in figure 12, the gripping finger 50 of adjacent sections 12 is connected on clamping limb 46 and 48.That is, on the elbow workpiece of one or four sections, the gripping finger 50 of the first and the 3rd section is installed on the clamping limb, and the gripping finger 50 of the second and the 4th section is installed on another clamping limb.Figure 12 shows the position that is in its " downwards " when clamping limb 46 and 48, and each gripping finger 50 can be with the section of separately elbow workpiece 52/54 free-standing ell rotary body 40 fixedly the time.
After each section 12 clampings, a clamping limb dextrorotation turn 90 degrees, and another clamping limb is rotated counterclockwise about 90 degree simultaneously.When clamping limb rotated, they rotated about 15 degree so that can follow the arcuate motion of elbow workpiece 52/54.Every secondary gripping finger 50 all is installed on clamping limb 46 and 48 by trochoid, so when elbow workpiece 52/54 rotation, these gripping fingers 50 can reverse together with elbow workpiece.As shown in figure 12, make the rotation of two clamping limbs 46/48 synchronous, and they are operatively coupled on two axles 58 by gears engaged by chain set.Therefore clamping limb 46 and 48 rotation make each independent section 12 of elbow workpiece 52/54 rotate to its final position, and form a complete ell 60 thus.Figure 13 shows the partial cross-sectional side view of this completed elbow workpiece 60, and wherein said clamping limb 50 has been finished rotating up of they.
As shown in figure 13, occupy the position that it " makes progress " once more in case clamping limb 46 and 48 rotates fully, gripping finger 50 will unclamp complete ell 60.Rotate this complete ell 60 with the direction pivot opposite then, in order to subsequently it is taken out from the shell 42 of free-standing ell rotary body 40 with putting into the elbow pipe fitting at first.
Figure 14 shows the partial cross-section end-view that is connected the secondary gripping finger 50 on the clamping limb 46/48.As shown in figure 14, the end of each gripping finger all has been equipped with an elastic buffer 62, and for example a urethane ester buffer is not limited to this certainly, and this buffer is used for the main body in the process protection elbow workpiece 52/54 of the free-standing ell rotary body 40 of operation.Utilize pneumatic cylinder 64 grades to make main body or expansion or the contraction of gripping finger 50 selectively with respect to elbow workpiece 52/54.
In addition, as shown in figure 15, the elbow workpiece 52/54 that the gripping finger of clamping limb 46/48 can optionally be configured to different-diameter is complementary.Promptly by changing the tie point 66 of gripping finger 50 on the clamping limb 46/48, and the tie point 68 that changes gripping finger 50 and cylinder 64, can realize accurately regulating the elbow workpiece 52/54 of different-diameter.As described below, at least one clamping limb 46/48 can also comprise slide bar 70, this slide bar 70 can optionally be located by friction fastening bolt etc., thereby extend to preset distance, therefore as shown in figure 16, in the process that clamping limb is rotated down, described slide bar can optionally also stop the rotation of clamping limb 46/48 thus with adjustable stop spare 56 adjacency.
Should be appreciated that each section 12 rotates a little and causes it with respect to other sections not point-blank usually when forming knuckle joint 16 when (as shown in Figure 1) in the ell make-up machine.Therefore each section must be realized different rotation amounts so that form suitable aligning in its rotation end.As mentioned above, a pair of gripping finger 50 that the present invention can predict on each clamping limb 46/48 can be installed on the slide bar 70, so that can before clamping limb 46/48 is rotated down fully it be stopped the rotation.When clamping limb 46/48 was rotated down, it can be parked on the different original positions to mate with the original position of respective elbow section 12.Therefore clamping limb can be parked in the position that is used for sliding gripping fingers 50, thereby mates with the original position of respective elbow section 12.When clamping limb 46/48 rotated up, the section 12 that has only those gripping finger 50 clampings that are fixed at first rotated, and reached on the position that sliding gripping fingers 50 stop up to clamping limb 46/48.In the process that continues rotation, sliding gripping fingers 50 and fixedly gripping finger 50 corresponding section 12 is rotated in the process of remainder.Therefore when rotating to of clamping limb was at the end, each section all was positioned at suitable separately place, final position.
Therefore it should be understood that to the invention provides a kind of rotary body that is used for elbow workpiece, this rotary body can be automatically be rotated each section of elbow workpiece, and therefore the method that tradition is wasted time and energy becomes automation mechanized operation.In addition, the present invention can also provide a kind of ell rotary body that links together with the ell make-up machine, therefore can be rotated each section when will be the elbow workpiece moulding, perhaps also can adopt a kind of free-standing ell rotary body, to be used for when the time, can carry out rotation simultaneously to whole sections of elbow workpiece to the elbow workpiece moulding.
