A kind of maintenance opening structure of straightener, comprise upper spider, lower bearing bracket, ejecting mechanism and smoothing roll, upper spider and lower bearing bracket side are by a hinge, and upper spider and lower bearing bracket opposite side are provided with described ejecting mechanism, ejecting mechanism comprises a telescopic piston rod, piston rod and upper spider hinged, rotated in vertical plane around bearing pin by the flexible upper spider that promotes of piston rod, smoothing roll be arranged in the middle part of upper spider with lower bearing bracket in the middle part of in the cavity that formed.
Further, described smoothing roll comprises top roll and lower roll, and top roll is arranged in upper spider cavity, lower roll is arranged in lower bearing bracket cavity, top roll comprises two of next-door neighbour's setting, and lower roll comprises three of next-door neighbour's setting, and each top roll correspondence is arranged on the top in the lower roll close neighbour face that two next-door neighbours are arranged.
Further, described top roll is connected with drive unit, by drive unit effect, top roll is elevated, to regulate the gap between lower roll.
Further, upper spider described in described piston rod jacking is 0 to 45 degree around the angular range that bearing pin rotates.
Further, described ejecting mechanism is a hydraulic jack.
Further, be formed with installation groove between described upper spider and lower bearing bracket, ejecting mechanism is arranged in this groove.
Further, one end of described ejecting mechanism opposing pistons bar to be coordinated with the pin-and-hole that lower bearing bracket is offered by a pin and affixed.
The maintenance opening structure of the utility model straightener passes through upper spider and lower bearing bracket pinned connection, again ejecting mechanism is arranged between upper spider and lower bearing bracket, being backed down by upper spider by ejecting mechanism makes upper spider can rotate around bearing pin, upper spider just can be opened and overhaul, this maintenance opening structure structure is simple, and opening speed is fast, efficiency is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of the maintenance opening structure of the utility model straightener.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually, below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
The maintenance opening structure of a kind of straightener shown in Fig. 1, comprises upper spider 10, lower bearing bracket 20, ejecting mechanism 30 and smoothing roll 40.
The top of upper spider 10 has a pin-and-hole 11, has pin-and-hole 12 in the bottom of opposite side, and upper spider 10 also comprises a bearing pin 13.
Lower bearing bracket 20 has pin-and-hole 21 and pin-and-hole 22, pin-and-hole 21 and pin-and-hole 11 homonymy, pin-and-hole 12 and pin-and-hole 22 homonymy.
Upper spider 10 carries out hinged by pin-and-hole 12, pin-and-hole 22 with bearing pin 13 with lower bearing bracket 20, and upper spider 10 can rotate around bearing pin 13, and angle is 0 to 45 degree.
Ejecting mechanism 30 is arranged between upper spider 10 and lower bearing bracket 20, and has the side of described pin-and-hole 11,21, and particularly, formed between upper spider 10 and lower bearing bracket 20 and install groove, ejecting mechanism 30 is arranged in this groove.The two ends of ejecting mechanism 30 are connected with upper spider 10 and lower bearing bracket 20 by pin-and-hole 11 and pin-and-hole 21.Ejecting mechanism 30 is a hydraulic jack, comprises a piston rod 31, piston rod 31 by a bearing pin and pin-and-hole 11 hinged.In the present embodiment, hydraulic jack model is HSGL-200/110E-1211-450, and diameter of cylinder is 200mm, and diameter of piston rod is 110mm, can bear larger pressure, can easily back down and close straightener upper spider 10.
Smoothing roll 40 to be arranged in the middle part of upper spider 10 in the cavity formed corresponding in the middle part of lower bearing bracket 10, smoothing roll 40 comprises top roll 41 and lower roll 42, top roll 41 is arranged in upper spider 10 cavity, and lower roll 42 is arranged in lower bearing bracket 20 cavity, and top roll 41 and lower roll 42 are all fixed by bearing block.And top roll 41 is connected with drive unit, top roll 41 can be made to be elevated by drive unit effect, thus regulate the gap between lower roll 42.Steel band gap between top roll 41 with lower roll 42 is passed and is coordinated with lower roll 42 pressing by top roll 41, realizes the aligning to steel band.In the present embodiment, top roll 41 is two that next-door neighbour is arranged, and lower roll 42 is three that next-door neighbour is arranged, the top in the lower roll 42 close neighbour face that each top roll 41 correspondence is arranged.
When straightener overhauls, lower bearing bracket 20 is motionless, and ejecting mechanism 30 stretches out piston rod 31 and backed down by upper spider 10, upper spider 10 can rotate in vertical plane around bearing pin 13, the angle of rotating is 0-45 degree, after upper spider 10 is opened, just can conveniently overhaul smoothing roll 40 or change.
To sum up, the maintenance opening structure of this straightener need not demounting bolt when overhauling, simply easy to maintenance, can save manpower and the amount of labour.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
