Abstract
The utility model relates to a hydraulic axial suspension device of a cardan shaft of a cold-rolling mill, which is characterized by comprising an axial suspension cylinder, a push plate, a guide rod, a clamping block and a seat frame, wherein the clamping block is connected with the guide rod through a coupling pin, one end of the guide rod is inserted into the guide hole of the seat frame, and the other end of the guide rod is connected with the push plate through nuts; the axial suspension cylinder is connected with the push plate and is arranged on the seat frame, and the whole device is mounted on a rack through bolts. The utility model has simple, compact and reasonable structure; under the action of the axial suspension cylinder, a transmission cardan shaft can be firmly suspended, thereby, advantages are provided to facilitate roller changing, such as higher automation degree, low labor intensity, short auxiliary time, high working efficiency, simple structure and convenient manufacturing.
Description
Technical field
The utility model relates to a kind of hydraulic suspension device for universal shaft of cold-rolling mill, specifically the hydraulic suspension device of 4-roller cold rolling mill working roll transmission universal drive shaft in the strap cold rolling equipment.
Background technology
At present, in widely used 4-roller cold rolling mill, the hydraulic suspension device for universal shaft of working roll transmission is not to be equipped with, and normally the method by artificial adjustment realizes.The replacing that is the working roll system in road, back like this brings sizable difficulty, has wasted the plenty of time, has strengthened labour intensity, greatly reduces the service efficiency of cold-rolling mill, has reduced the benefit of enterprise.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of automaticity higher, and labour intensity is little, and non-cutting time is few, high efficiency, and the hydraulic suspension device for universal shaft of cold-rolling mill that can provide convenience for the replacing of back road working roll system.
The technical scheme that provides according to the utility model, hydraulic suspension device for universal shaft of cold-rolling mill comprises seize oil cylinder, push pedal, guide rod, clamp, mounting, described clamp by connecting pin be connected with guide rod, guide rod one end is inserted in the guide hole of mounting, the guide rod other end is connected with nut with push pedal; The seize oil cylinder is connected with push pedal, and the seize oil cylinder is installed on the mounting, and package unit is installed on the frame with bolt.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Owing to, just the transmission universal drive shaft can be held tightly by the seize cylinder action, provide advantage for making things convenient for roll change, automaticity is higher, and labour intensity is little, and non-cutting time is few, high efficiency, and simple in structure, easily manufactured.
Description of drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model user mode schematic diagram.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1 and Figure 2, comprise seize oil cylinder 1, push pedal 2, guide rod 3, connecting pin 4, clamp 5, mounting 6, frame 7 and universal drive shaft 8 etc.
The hydraulic suspension device for universal shaft of the utility model 4-roller cold rolling mill working roll transmission adopts clamp 5 to be connected with guide rod 3 by connecting pin 4, and guide rod 3 one ends are inserted in the guide hole of mounting 6, and guide rod 3 other ends and push pedal 2 usefulness nuts link together; Seize oil cylinder 1 also is with nut push pedal 2 to be coupled together, and seize oil cylinder 1 is installed on the mounting 6, and package unit is installed on the frame 7 with bolt.
In Fig. 1, Fig. 2, when cold-rolling mill need be changed working roll and is, open seize oil cylinder magnetic valve earlier, make 1 action of seize oil cylinder, piston rod stretches out (two side seize oil cylinders are worked simultaneously), and piston rod promotes push pedal 2 and moves horizontally, and push pedal 2 promotes guide rod 3 and moves, guide rod 3 moves axially in the guide hole of mounting 6, and this moment, guide rod 3 played the effect of guiding and location.Guide rod 3 links together by connecting pin 4 and clamp 5, promotes clamp and moves, and holds universal drive shaft 8 tightly, makes universal drive shaft 8 remain at same position.Because the axis hole of universal drive shaft 8 entangles the working roll spindle nose, so working roll also is in same position.When changing working roll, as long as firmly believe a direction, just can easily the spindle nose of working roll and the axis hole of universal drive shaft 8 be assembled, avoided rocking the drawback that is difficult to assemble because of no lock shaft apparatus makes universal drive shaft head axis hole at replacing working roll spindle nose, a large amount of non-cutting times have been saved, improve production efficiency, also guaranteed production safety simultaneously.
