(5) detailed description of the invention
The enlarging cup selecting arrangement of a kind of electric tube expander as depicted in figs. 1 and 2, comprise frame (not shown in FIG.), and be arranged on slip die holder (not shown in FIG.) in this frame and some expander rolls 1 slippingly, expander roll 1 comprises expander roll body 13 and is located at the swollen ball 14 of expander roll body end.The rack-mounted enlarging slide 2 of a slip is also had below described slip die holder.Expander roll 1 quantity of electric tube expander is selected to adopt the patent No. for the concrete structure of the expander roll selecting arrangement of a kind of electric tube expander disclosed in 201320683116, and the quantity that automatically can realize expander roll 1 is selected.
Described enlarging slide 2 is provided with the selector channel 3 corresponding with each described expander roll 1, particularly, described enlarging slide 22 comprises fixed head 21 and location-plate 22, described fixed head 21 is provided with the first through hole 21-1, location-plate 22 is provided with the second through hole 22-1, described fixed head 21 is installed on the upper surface of location-plate 22, and described first through hole 21-1 and the second through hole 22-1 coaxially arranges and forms selector channel 3.The diameter of the first through hole 21-1 is greater than the diameter of described second through hole 22-1, and therefore, selector channel 3 can be called shoulder hole.
As shown in Figure 3, described enlarging slide 2 is provided with in each selector channel 3 correspondence the chamber 22-2 be connected with selector channel 3, particularly, each chamber 22-2 digs on the upper surface of described location-plate 22.
Each selector channel 3 is provided with a pushing sleeve 4, and shown in Fig. 4, described pushing sleeve 4 upper end has a neck 41, and the excircle diameter of neck 41 is less than the excircle diameter of described pushing sleeve 4, and the upper end of pushing sleeve 4 has a cap bag 42.Described pushing sleeve 4 sidewall is provided with one axially to extend along pushing sleeve 4 and to pass the fluting 43 of described neck 41, this fluting 43 opens the lower surface to cap bag 42.Cap bag 42 is seated in the first through hole 21-1 to be avoided degenerating from enlarging slide 2 when using, and enlarging cup 5 is successively docked through after the first through hole 21-1 and the second through hole 22-1 in the lower end of described pushing sleeve 4, the lower end of enlarging cup 5 is provided with flaring head 51 to carry out enlarging to the port of copper pipe.
Each pushing sleeve 4 is furnished with a lock pushing sleeve mechanism respectively.Lock pushing sleeve mechanism is arranged on enlarging slide 2, and each described lock pushing sleeve mechanism comprises the latch segment 6 be located between described selector channel 3.Specifically, described latch segment 6 comprises latch segment body 61, the tight lock part 62 be connected with latch segment body 61 and the portion 63 that is excited, a rotating shaft 22-21 is provided with in described chamber 22-2, latch segment body 61 be provided with coordinate with described rotating shaft 22-21 turn hole 63, turning hole 63 described in described rotating shaft 22-21 passes makes described latch segment 6 be installed in rotation in described chamber 22-2, the described portion 63 that is excited puts in described pushing sleeve 4 through the fluting 43 of described pushing sleeve 4, and described tight lock part 62 is in the periphery of pushing sleeve 4.
Enlarging cup selecting arrangement also comprises exciting locks pushing sleeve mechanism to fix or to unclamp the excitation mechanism of pushing sleeve 4, even if latch segment 6 switches between a locked position and a unlocked position, specifically, each root expander roll 1 all has the comparatively segment 11 that one section of excircle diameter is less than the excircle diameter of described expander roll 1, comparatively segment 11 upper end of described expander roll 1 is provided with chamfering 12, and this chamfering 12 can form described excitation mechanism.
Expander roll 1 is successively through pushing sleeve 4 and enlarging cup 5.
When described expander roll 1 relatively pushing sleeve 4 axially-movable make the portion of being excited 63 when excitation mechanism (chamfering 12), latch segment 6 rotates around it axle clockwise or rotate counterclockwise the neck 41 tight lock part 62 being embraced or unclamps pushing sleeve 4.
The elastic component 7 that latch segment 6 is resetted also is provided with between latch segment body 61 and chamber 22-2 internal face.This elastic component 7 is spring.
In use procedure, enlarging slide 2 is first followed slip die holder and is moved downward together, expander roll 1 arrives copper pipe end when preparing expand tube, and enlarging slide 2 maintains static, and selected expander roll 1 under the continuation of slip die holder promotes relatively pushing sleeve 4 do axially-movable expand tube carried out to the copper pipe be fixed on below it.
Referring to accompanying drawing 5 to Figure 12, in expand tube process, be excited the non-small section that compared with segment 11 through chamfering 12 enter expander roll 1 of portion 63 by expander roll 1, the portion 63 that is excited is excited and creates rotation (from accompanying drawing 6, its rotation direction is for rotating counterclockwise), make tight lock part 62 embrace the neck 41 (shown in Fig. 5 to Fig. 8) of pushing sleeve 4, the upper end of pushing sleeve 4 is locked in selector channel 3 by Shi Suo pushing sleeve mechanism.
In above-mentioned expand tube process, the portion 63 that is excited is in the non-small section of expander roll 1 always, therefore, tight lock part 62 keeps the state of the neck 41 embracing pushing sleeve 4 always, after expand tube terminates, enlarging slide 2 moves downward with pushing sleeve 4, makes the port of the enlarging cup 5 pairs of copper pipes being installed on pushing sleeve 4 lower end carry out enlarging.
After enlarging terminates, expander roll 1 relatively pushing sleeve 4 moves upward, and make the portion of being excited 63 enter comparatively segment 11 from the non-small section of expander roll 1 through chamfering 12, under the effect of elastic component 7, latch segment 6 is reset (shown in Fig. 9 to Figure 12).
In above-mentioned expand tube process, the decline of slip die holder, for and those not selected expander rolls 1, motion is each other uncorrelated, in the decline process of i.e. slip die holder, not selected expander roll 1 is actually motionless, also can refer to shown in Fig. 9 to Figure 12, in this process, the portion 63 that is excited is in the comparatively segment 11 of expander roll 1, cannot excite the portion of being excited 63 that latch segment 6 is rotated, therefore along with the motion of enlarging slide 2, also owing to being subject to the support compared with segment 11 lower end, the upper end of pushing sleeve 4 can pass from selector channel 3, with enlarging slide 2 from, thus do not participate in the action of enlarging.
Thus achieve the object that enlarging cup is selected in automation.
Above-described embodiment is better embodiment of the present invention; but embodiments of the present invention are not limited thereto; other are any do not deviate from Spirit Essence of the present invention and principle under do change, modification, substitute, combine, simplify; be the substitute mode of equivalence, be included within protection scope of the present invention.
