Description
Technical field
The utility model relates to straight welded pipe production line band steel conveying technology, relates in particular to hump roller-way strip steel at entry conveying device.
Background technology
The hump roller-way is the standard configuration of straight welded pipe production line, is positioned at edge milling machines 16, mills behind the limit portion before the profiled section after the failure detector 17 19, referring to Fig. 1.Hump roller-way 18 effect is the flexible guiding that is used to steel 15, will have the center that band steel behind the limit is directed to roll line of milling of the camber that do not exceed standard, so as continuously precise forming, high-frequency heating extruding joint close, remove inside and outside burr and become pipe.Welded tube line stream time depends on factors such as internal hair thorn blade life-span.And before back recurrence weldering was handled in each shutdown, technological requirement must be moveed backward make-up machine and be made the online band steel that is in different moulding degree to supplied materials direction slow astern segment distance.Since after the pinch roll 13 of edge milling machines 16 inlet before the entrance pinch roll 14 of profiled section 19; original processing line does not dispose any band steel restraint device; reversing before the recurrence weldering must cause being with steel arch camber place not controlled therebetween; often not in the 18 position arch cambers of hump roller-way; and the arch of failure detector 17 places between edge milling machines 16 and hump roller-way 18; cause flaw detection probe suspension arrangement to be damaged and shut down and rush to repair, had a strong impact on welded tube line ordinary production by arch camber band steel.
Summary of the invention
The purpose of this utility model is to provide a kind of hump roller-way strip steel at entry to retreat restraint device; this device solves welded tube line not controlled problem in band steel arch camber place when shutting down before the start again the technology reversing; this apparatus structure compactness; braking is direct, reliable, and has improved the body of roll downwarp situation of hump roller-way entrance pinch roll lower roll.
The utility model is achieved in that a kind of hump roller-way strip steel at entry retreats restraint device, comprise brake block, slide plate, base, hydraulic cylinder, flexible connected body, hydraulic cylinder is equipped with in base central authorities, on the base biside plate slide plate is housed, brake block is housed between the slide plate, the brake block bottom links through flexible connected body with hydraulic cylinder, and the brake block top is an arc-shaped concave, and arc-shaped concave matches with pinch roll lower roll barrel diameter.
Described flexible connected body is the sphere coupling head, and the brake block bottom has the groove surface that matches with the sphere coupling head, and sphere connects first end and connects hydraulic cylinder piston rod, and the other end is in flange is connected brake block bottom groove face.Gluing brake rubber block on the arc-shaped concave of brake block top, brake rubber block contacts with the body of roll.
The guiding pressing plate is equipped with in the limit portion of described slide plate, and guiding pressing plate restriction brake block is traversing.
The utility model is in the middle part of being installed at the bottom of the hump roller-way entrance pinch roll lower roll roller, on the pinch roll apparatus base top board.Because hump roller-way entrance pinch roll is the door of hump roller-way, it is again the critical point that the check strap steel is retracted into failure detector, this pinch roll is the passive type pinch roll, therefore the utility model retreating to the Brake Energy check strap steel of hump roller-way entrance pinch roll, the check strap steel is retracted into failure detector, thereby avoids the infringement to failure detector.And can improve hump roller-way entrance pinch roll lower roll and clamp the body of roll downwarp situation that causes because of the band steel.
The utility model compact conformation, firm; braking directly, reliably; installation position is reasonable; and can improve the body of roll downwarp situation of hump roller-way entrance pinch roll lower roll; solve the shutdown of welded tube line and be with the not controlled problem in steel arch camber place when the preceding technology of start is moveed backward again, guaranteed the normal operation of straight welded pipe production line.

Fig. 2 retreats the restraint device structural representation for the utility model hump roller-way strip steel at entry;
Fig. 3 is the side view of Fig. 2;
Fig. 4 is the vertical view of Fig. 2.
Among the figure: 1 brake block, 2 guiding pressing plates, 3 sphere coupling heads, 4 slide plates, 5 bases, 6,7 bolts, 8 flanges, 9 screws, 10 hydraulic cylinders, 11 brake rubber blocks, 12 pinch roll lower rolls (passive pinch roll), 13,14 active pinch rolls, 15 band steel, 16 edge milling machines, 17 failure detectors, 18 hump roller-ways, 19 profiled sections.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 2, Fig. 3, Fig. 4, a kind of hump roller-way strip steel at entry retreats restraint device, comprises brake block 1, slide plate 4, guiding pressing plate 2, base 5, hydraulic cylinder 10, sphere coupling head 3, flange 8.Hydraulic cylinder 10 is equipped with in base 5 central authorities, is equipped with between 4, two slide plates 4 of slide plate through bolt 6,7 on base 5 biside plates brake block 1 is housed, and through bolt 7 guiding pressing plate 2 is housed in the limit of slide plate 4 one, and guiding pressing plate 2 restriction brake block 1 are traversing.Brake block 1 bottom has the groove surface that matches with sphere coupling head 3, and sphere coupling head 3 one ends connect hydraulic cylinder 10 piston rods, and the other end is connected in the brake block 1 bottom groove face by flange 8, and flange 8 is fixed on brake block 1 bottom by screw 9.Brake block 1 top is an arc-shaped concave, and gluing brake rubber block 11 on the arc-shaped concave, brake rubber block 11 match to merge with pinch roll lower roll 12 barrel diameters and contact with it.
It is clear and definite and be accurately positioned under the pinch roll lower roll 12 after the central authorities on pinch roll base top board that hump roller-way strip steel at entry retreats restraint device, and base 5 base plates and the pinch roll apparatus base top board of restraint device are fixed with intermittent weld.
Hump roller-way strip steel at entry retreats the operation principle of restraint device:
In case the welded tube line is shut down, 24 logical hydraulicdirectional control valves get TURP and change, hump roller-way strip steel at entry retreats 10 sides of hydraulic cylinder (cylinder bottom) oil-feed, the oil extraction of bar side of restraint device, hydraulic cylinder 10 piston rods are through sphere coupling head 3 jacking brake block 1 central authorities at the bottom of brake block brake rubber block 11 presses pinch roll lower roll 12 rollers at once, and this passive pinch roll 12 that be in clamped condition this moment promptly is braked; When profiled section reversing band steel retreats, above-mentioned reversal valve still be in electricity condition, the band steel that retreats is hampered by keeps this passive pinch roll 12 that clamps on-position, in the place's arch camber of hump roller-way; The welded tube line plays weldering again, make the arch of hump roller-way place band steel be decreased to safe altitude shake-up level switch, the reversal valve dead electricity resets, hydraulic cylinder 10 bar side oil-feeds, a side oil extraction, immediately bounce back brake block 1 of its piston rod descends, this passive pinch roll 12 is the brake off state immediately, the extensive overlying strip condition that moves ahead.
The utility model compact conformation, firm; braking directly, reliably; installation position is reasonable; and can improve the body of roll downwarp situation of hump roller-way entrance pinch roll lower roll; solve the shutdown of welded tube line and be with the not controlled problem in steel arch camber place when the preceding technology of start is moveed backward again, guaranteed the normal operation of straight welded pipe production line.
