Abstract
The utility model belongs to the field of roll operation, and relates to a press oil cylinder replacement device. The press oil cylinder replacement device comprises an upper pressing plate and a lower pressing plate as well as a hanging bolt and lock bolts which are matched with the pressing plates, and the hanging bolt and the lock bolts are matched with gland nuts; the press oil cylinder replacement device is characterized in that the upper pressing plate and the lower pressing plate are respectively provided with three screw holes, the screw hole at the middle of the lower pressing plate is a long hole, the hanging bolt is positioned in the long hole, and the lock bolts are positioned in the screw holes on the two ends; when the replacement device is in a clamping state, the upper pressing plate and the lower pressing plate clamp the two wings of an oil cylinder so as to fix through the lock bolts and the hanging bolt; and when the replacement device is in a replaced state, the lock bolts are released, the gland nuts of the hanging bolt are loose, the lower pressing plate slides to the outside along the long hole, and the oil cylinder drops into a tray on the bottom. The device adopts a dexterous mechanical structure, can realize the reliable installation or dismantlement of the press oil cylinder only by screwing or loosening the two nuts, and provides a press oil cylinder suspension device which is simple and convenient and is safe and reliable in performance for a six rolling mill operating line.
Description
Technical field
The utility model belongs to milling train operation field, is more changing device of a kind of depress oil cylinder.
Background technology
In line of rolling apparatus, each frame has two depress oil cylinders, for widestrip mill; The diameter dimension of single depress oil cylinder often surpasses 1000mm; Weight can reach the 5-6 ton, so its installation, safeguard to change and all to require its suspension arrangement simple and reliable, wants during replacing fast, simple.Conveniently suspension arrangement can shorten milling train installation and maintenance time greatly, improves the production efficiency of milling train.Mostly at present external import milling train method in this respect is: totally four hydraulic cylinders in front and back are fastening, when changing depress oil cylinder, and the hydraulic cylinder withdrawal, depress oil cylinder is fallen on the track of special setting, and manual work is pulled out the master cylinder side direction with steel cable.The shortcoming of this method is: the first, increased the equipment input.Before and after totally four hydraulic cylinders and pipeline, also have two and change the cylinder track, second, the space at memorial archway top becomes narrow and small, service equipment is constant.
Domestic present method is to rely on directly with a plurality of bolts depress oil cylinder to be put together on the memorial archway top, and during replacing, dismantling a plurality of bolts wastes time and energy, and the defective of this way is that hand labor intensity is big, causes and changes depress oil cylinder time length, influences labor productivity.
Summary of the invention
The purpose of the utility model provides more changing device of a kind of depress oil cylinder, realizes quick, simple, safe replacing depress oil cylinder.
The technical scheme of the utility model is a more changing device of depress oil cylinder; It comprises top board and lower platen and with supporting Hanging bolt and the clamping screw of pressing plate; Hanging bolt and clamping screw all are furnished with clamp nut, it is characterized in that: top board and lower platen respectively have three screws, and the screw in the middle of the lower platen is a slotted hole; Hanging bolt is positioned at slotted hole, and clamping screw is positioned at the both sides screw; During clamp position, top board and lower platen are clamped the oil cylinder both wings, and fix through clamping screw and Hanging bolt; During the replacing state, remove clamping screw, the clamp nut of loosening Hanging bolt slides lower platen along slotted hole laterally, and oil cylinder falls into bottom tray.
The width of described top board and lower platen is greater than oil cylinder both wings width.
Described lower platen is step-like, and low step surface width is greater than oil cylinder both wings width, and slotted hole runs through high and low two step surfaces, and the both sides screw is positioned at high step surface.
The characteristics of the utility model are to adopt dexterous frame for movement, only need tighten or return two nuts of pine, just can realize the reliable installation or removal of depress oil cylinder, are that six line of rolling apparatus provide a kind of simple and convenient, depress oil cylinder suspension arrangement that performance is safe and reliable.
Description of drawings
To combine embodiment that the utility model is further described below.
Fig. 1 is the lower platen structural representation;
Fig. 2 is a more changing device front view of depress oil cylinder;
Fig. 3 is that depress oil cylinder is changed the device side view;
Fig. 4 is that depress oil cylinder is changed the apparatus structure sketch map.
Among the figure: 1, lower platen; 2, top board; 3, press down the plate hight step surface; 4, the low step surface of lower platen; 5, slotted hole; 6, screw; 7, clamping screw; 8, Hanging bolt; 9, clamp nut.
The specific embodiment
Embodiment: as shown in Figure 1; Depress oil cylinder is changing device more, it comprise top board 2 and lower platen 1 and with the supporting Hanging bolt 8 and clamping screw 7 of pressing plate, Hanging bolt 8 all is furnished with clamp nut 9 with clamping screw 7; It is characterized in that: top board 2 respectively has three screws 6 with lower platen 1; Screw 6 in the middle of the lower platen 1 is slotted holes 5, Hanging bolt 8 supporting slotted holes 5, clamping screw 7 supporting both sides screws 6.
The width of described top board and lower platen can be greater than oil cylinder both wings width.
Like Fig. 2, shown in 3 and 4, top board 2 is dull and stereotyped, and has three screws 6 to cooperate with two screws 6 and a slotted hole 5 of lower platen 1.
Under the clamp position; Top board 2 and lower platen 1 are with the clamping of oil cylinder both wings; The oil cylinder both wings drop on the low step surface 4 of lower platen; Clamping screw 7 is positioned at both sides screw 6 and upper and lower pressing plate is fixed, and Hanging bolt 8 is arranged in middle screw and places the middle slotted hole 5 of lower platen 1, and each bolt all has clamp nut 9.Clamping screw 7 can prevent the slip of pressing plate.
Under the replacing state, at first pallet is placed under the oil cylinder, remove clamping screw 7, and the clamp nut 9 of loosening Hanging bolt 8, lower platen 1 is slided along slotted hole 5 laterally, when the oil cylinder both wings left lower platen and hang down step surface 4, oil cylinder fell in the pallet; Shelf by the special replacement oil cylinder pushes new oil cylinder simultaneously, and lower platen 1 is slided to the inside, makes upper and lower pressing plate grasp new oil cylinder both wings, tightens the clamp nut of Hanging bolt 8, and clamping screw 7 is installed, and accomplishes the replacing of oil cylinder.
It is low, simple and compact for structure that this depress oil cylinder suspension arrangement has cost of investment, and safe and reliable, the flexible and convenient operation of performance can be used in the various line of rolling apparatus.This device has been successfully applied in many cover line of rolling apparatus.
It should be noted that well-known components and common structure or conventional means that parts that present embodiment is not described in detail and structure belong to the industry, here narration one by one.
