Description
Technical field
The utility model relates to a kind of modern H shape rolling mill, the locking and the device for opening of particularly a kind of rolling-mill housing and guide rail.
Background technology
Represent the H shaped steel rolling line equipment of one of world's advanced technology, its omnipotent mm finishing mill unit frame design is portable, to satisfy the requirement of fast roll changing.But when rolling, require again rolling stable, do not allow and guide rail between produce and move.This just needs a kind of device can guarantee milling train: frame and guide rail can be locked securely when rolling, and frame can freely move along guide rail during roll change.
The locking and the device for opening of existing omnipotent mm finishing mill unit frame and guide rail all adopt hydraulic way, and are finished by the reciprocating hydraulic cylinder; This device adopts hydraulic pressure dynamically to control, and opens and lock very fast.But shortcoming is a complex structure, and not only will provide operating pressure constantly in the operation of rolling is the hydraulic oil of 35MPa, also need remain pressure stability, and this reciprocating hydraulic cylinder must be a beidirectional.Every in UR/UF milling train has two locking cylinders, edging mill has four locking cylinders, UR/E/UF 8 two-way cylinders of having added up, so many locking cylinder fuel feeding all the time in the operation of rolling, and be in the long-term work state, increase valve group live load, also increased the energy consumption of pumping plant and valve group, more increased accident point simultaneously.
As shown in Figure 2, existing fluid pressure type frame and guide rail locking mainly partly are made up of piston, saturating lid, support set I, cylinder body, support set II, end cap, alignment pin, spacer pin etc. with device for opening, this locking device has two on the portable memorial archway of each sheet, be the benchmark symmetric arrangement with the memorial archway center line.Its operation principle is as follows: when rolling-mill housing and guide rail need be locked, the hydraulic fluid port oil-feed of piston right side, piston is moved to the left, the piston right-hand member has a low-angle inclined-plane, the inclined-plane that a same angle is also arranged on the rolling-mill housing guide rail, piston moves on to after inclined-plane on the rolling-mill housing overlaps, piston right side hydraulic fluid port continues fuel feeding, and the operating pressure and the pressurize that oil pressure are risen to set, make and produce desired stable thrust between piston and rolling-mill housing plurality of ramps, under the situation of rolling-mill housing and guide rail locking, can be rolled; When rolling-mill housing need be separated with guide rail, the hydraulic fluid port oil-feed of piston left side, piston moves right, and piston left end low-angle inclined-plane separates certain distance with plurality of ramps, and rolling-mill housing just can move freely along guide pass like this.
The advantage of this device is locking and open soon, and shortcoming is no matter in the operation of rolling or in the roll change process, and hydraulic cylinder is wanted fuel feeding constantly, especially in the operation of rolling, not only wants fuel feeding constantly, and will remain pressure stability.
Summary of the invention
Be to solve the problems referred to above that prior art exists, the utility model will propose a kind of load that can reduce hydraulic system, saves energy resource consumption, reduces cost, reduces accident point, non-maintaining or safeguard, increase the service life, improve the rolling-mill housing of rolling stability and the locking and the device for opening of guide rail less.
To achieve these goals, the technical solution of the utility model is as follows: the locking of a kind of rolling-mill housing and guide rail and device for opening comprise piston, saturating lid, support set, cylinder body, end cap, alignment pin, spacer pin; Described piston is installed in the cylinder body by sealing ring; Described support set outer surface is fixedly mounted in the cylinder body by sealing ring, and inner surface is slidingly connected by the piston rod of sealing ring and piston left end; Described lid is installed in the left end of cylinder body by high-strength bolt, and pushes down the left side of support set; Described piston is the piston of single effect cylinder; Disk spring also is installed on the guide post of piston right-hand member; Right-hand member at described disk spring is equipped with end cap; Described end cap is installed in the right-hand member of cylinder body and compresses disk spring by high-strength bolt; On described end cap endoporus alignment pin is housed, the other end of alignment pin inserts in the locating slot of piston right-hand member guide post; Described spacer pin is installed in the piston right-hand member guide post by interference fit.
The diameter of the guide post of the dress disk spring of piston right-hand member described in the utility model is about half of piston diameter, radially offers locating slot on the guide post.
Inboard wall of cylinder block described in the utility model have one can limited piston the step of limit travel, the internal diameter in left side is greater than the internal diameter on right side, right side inner surface of cylinder block machining accuracy is lower than left side inner surface of cylinder block machining accuracy.
The endoporus of end cap described in the utility model radially has the hole of a dress alignment pin.
Compared with prior art, the utlity model has following beneficial effect:
1, because the utility model changes the piston of the two-way function cylinder of prior art in the piston of single effect cylinder, the locking of rolling-mill housing and guide rail is changed into by original hydraulic locking and adopts disk spring locking, because the life-span of the selected disk spring of the utility model is more than 100,000 times, operating mode according to this place, can use more than 16 years, saved simultaneously and formerly made the necessary high-pressure hose of cylinder action, thereby realized the purpose of reliable in action, long service life.
2, because the utility model does not need fuel feeding in the locking of operation of rolling mid frame and guide rail, simplify the function of pumping plant and hydraulic valve bank, simplified the structure of pumping plant and hydraulic valve bank, reduced cost, reduced accident point, improved rolling stability.Adopt the utility model can save 3～40,000 yuan of valve group costs, save 5～60,000 yuan of accumulator costs, save plant equipment pipe arrangement quantity, cost saving is more than at least 2 ten thousand yuan, and direct economic benefit is more than 150,000 yuan.To the user, can save energy resource consumption, reduce noise, reduce environmental pollution, its social benefit is huge.
3, because employing disk spring of the present utility model locking has replaced hydraulic locking, so after device once assembles qualified and uses, can accomplish non-maintaining.
4, since inboard wall of cylinder block of the present utility model have one can limited piston the step of limit travel, the internal diameter in left side is greater than the internal diameter on right side, right side inner surface of cylinder block machining accuracy is lower than left side inner surface of cylinder block machining accuracy.
5, end cap of the present utility model inboard is to be operated in low-pressure area, does not need high voltage bearing sealing at sliding surface, then needs high voltage bearing sealing at sliding surface in the prior art, increases manufacturing cost, also increases accident point simultaneously.
