Described expander roll is locked to comprise eccentric locked and concentric locked (seeing Fig. 4, Fig. 5, Fig. 6, Fig. 9, Figure 10) two parts:
(1) eccentric locked.Eccentric lockedly realize the automatic whereabouts of (when expander roll locking is unclamped) expander roll (45) when being used for preventing from loading and unloading expander roll (45) by the off-centre operation of expander roll (45) and the lock ring (25) between each orifice plate and jam plate and rubber spring (26); The moving operation of eccentric locked still armrest, after expander roll inserted gang form, lock ring snapped in the off-centre operation place of expander roll under the effect of rubber spring, thereby expander roll is locked, when unloading expander roll, as long as expander roll can be unloaded expander roll towards 90 ° of any direction rotations;
(2) locked with one heart.Concentric locked concentric ladder cylinder by expander roll (45) is that realize in the flat hole of the minimum place of expander roll diameter and sleiding form, is used for preventing that expander roll from coming off owing to expander roll (45) rotates when swollen copper pipe processed; The gang form of tradition staged electric tube expander and the expander roll on the ladder bar all are that the moving off-centre operation of armrest is locked usually, and this utility model has also realized being automatically locked with one heart of automatic control.During work, confirm that at first " expander roll locking " button on the display screen is in the position of " unclamping ", show that circular hole part and lockhole on each gang form and the ladder bar sleiding form are in relative position this moment, then insert the expander roll (45) of respective numbers at each template and ladder bar according to the hole count of heat exchanger, again " the expander roll locking " on the crawl control panel, at this moment be fixed on locking cylinder action on each gang form and the ladder bar, driving the sleiding form that is connected separately slides, allow the minimum part of diameter of expander roll (45) as shown in Figure 9 slide among the flat hole by passing as shown in Figure 3 slide plate circular hole, because the width in flat hole is basically identical on expander roll (45) shaft minimum diameter and the slide plate, and then it is locked effectively with one heart to have realized that expander roll (45) moves up and down;
The employed cylinder of the utility model is magnetic air cylinder, on each magnetic air cylinder all with magnetic switch, therefore the action of all cylinders is all controlled its operation by PLC by air operated reversing valve, and shows duty and the concrete operations of cylinder by control panel.
The utility model process portion can be carried out respectively as follows:
(A) without the ladder expand tube;
(B) the upper ladder expand tube of two rows;
(C) the upper ladder expand tube of three rows;
(D) downstairs expand tube.
For (A) without the ladder expand tube:
In the capacity of equipment scope, no matter expand and make the product of several rounds, all need ladder bar one (11), ladder bar two (12) are risen to limes superiors, so that movable template is that ladder bar one (11) and ladder bar two (12) are that gang form one (17) and gang form two (22) are fixed on the same installation horizontal plane of plate supporting frame (1) jointly with fixed form; For traditional upper staged electric tube expander, this process all is to be climbed on the equipment by artificial mode by the operator to realize usually, and the utility model only needs " ladder bar one rises " and " two risings of ladder bar " on the operation control flow on operator's crawl control panel automatically to realize.
The lifting drive of described ladder bar one (11) and ladder bar two (12) comes from ladder bar one lift cylinder (5) and ladder bar two lift cylinders (6); Described axle one (16), axle two (15) and linear bearing (8) provide guiding for the lifting of ladder bar one (11) and ladder bar two (12); After described ladder bar one (11), ladder bar two (12) rise to limes superiors, " one locking of ladder bar " on the crawl control panel and " two lockings of ladder bar ", then be positioned at two two-stage gas cylinders (18) action of plate supporting frame (1) left and right sides, two dead bolts (21) of being installed in respectively in two lock dog seats (19) groove are stretched out with the piston rod of two two-stage gas cylinders (18), thereby ladder bar one (11) and ladder bar two (12) automatically are locked on the same installation horizontal plane with gang form one (17) and gang form two (22).
The utility model (is seen Fig. 1 for swollen system without the heat exchanger of ladder, Fig. 2, Fig. 3), (the adjustment principle that is less than four rows is substantially identical when the heat exchanger more than swollen system four rounds, the descriptions thereof are omitted at this), should confirm first that at first " expander roll locking " button on the display screen is in the position of " unclamping ", then according to the hole count of heat exchanger at gang form one (17), gang form two (22), ladder bar one (11) and ladder bar two (12) the upper expander rolls (45) that insert respective numbers, then " the expander roll locking " on the crawl control panel, at this moment be fixed on the two rod locking cylinders (3) on the gang form one (17), be fixed on the finger type locking cylinder one (23) on the gang form two (22), the finger type locking cylinder three (36) that is fixed on the finger type locking cylinder two (35) on the ladder bar one (11) and is fixed on the ladder bar two (12) moves, drive gang form one sleiding form (27), gang form two sleiding forms (28), ladder bar one sleiding form (29) and ladder bar two sleiding forms (30) slide, allow the minimum part of diameter of expander roll (45) as shown in Figure 9 slide among the flat hole via passing as shown in Figure 3 slide plate circular hole, because the width in flat hole is basically identical on expander roll (45) shaft minimum diameter and the slide plate, and then has realized that expander roll (45) moves up and down by effectively locked with one heart.
