Abstract
The utility model discloses an anti-rotating device comprising a cylinder body and a pressing cover. The cylinder body is fixedly connected with the pressing cover; a flange is fixedly arranged on the pressing cover; an anti-rotating key is coupled on the pressing cover through a bolt and a piston in the cylinder body is fixedly connected with a protection cover; the protection cover is provided with a long hole; and an anti-rotating key is arranged in the long hole. The anti-rotating device disclosed by the utility model is used for an upper press cylinder of a six-roller mill, limits the rotation of the protection cover through the anti-rotating key arranged on the pressing cover and also avoids an oil leaking phenomenon. The anti-rotating device is simple in structure and is convenient and practical.
Description
Technical field
The utility model belongs to the mechanical designing technique field, relates to a kind of six-high cluster mill and presses the anti-rotation device that uses in the cylinder.
Background technology
Along with improving constantly of science and technology development and industrial equipment level, the continuous casting and rolling of band steel has obtained extensive use.In the tradition steel rolling equipment,, also there is not good solution now because the defective of structure makes that pressing cylinder flange place exists the leakage of oil situation.
Summary of the invention
The purpose of the utility model has provided a kind of anti-rotation device, prevents the cylinder body leakage of oil.
The technical scheme of the utility model is that a kind of anti-rotation device comprises cylinder body and gland; Cylinder body is fixedly connected with gland; Be fixed with flange on the gland, closing on gland, the piston in the cylinder body is fixedly connected with protective cover antirotation keys through bolt; Protective cover is provided with slotted hole, and antirotation keys is arranged in the slotted hole.
The characteristic of the utility model also is,
Be provided with the O RunddichtringO between flange and the gland.
The anti-rotation device of the utility model is used for six-high cluster mill and presses cylinder and use, through being installed on the rotation of the antirotation keys restriction protective cover on the gland.During oil cylinder work, oil-feed and oil return all possibly cause piston rotation, thereby drive the protective cover rotation.The excessive rotation of protective cover must be bumped against with flange, and the repeatedly collision of positive and negative both direction, is easy to cause flange bolt loosening, and then destroys sealing surface, causes leakage of oil.But the setting of antirotation keys has limited the rotation of protective cover, has also prevented the generation of oil leakage phenomenon.Simple in structure, convenient, practical.
Description of drawings
Fig. 1 is the structural representation of the utility model anti-rotation device.
Among the figure, 1. cylinder body, 2. piston, 3. gland, 4. antirotation keys, 5. protective cover, 6.O RunddichtringO, 7. flange.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
The structure of the utility model anti-rotation device, as shown in Figure 1.Comprise cylinder body 1 and gland 3, cylinder body 1 is fixedly connected with gland 3, is fixed with flange 7 on the gland 3, and closing on gland 3, the piston 2 in the cylinder body 1 is fixedly connected with protective cover 5 antirotation keys 4 through bolt, and protective cover 5 is provided with slotted hole, and antirotation keys 4 is arranged in the slotted hole.Between flange 7 and the gland 3 O RunddichtringO 6 is housed.
The utility model anti-rotation device is through being installed on the rotation of the antirotation keys 4 restriction protective covers 5 on the gland 3.During cylinder body work, the piston 2 that oil-feed and oil return cause (protective cover 5) rotation all will be limited by antirotation keys 4, thereby prevent the generation of oil leakage phenomenon dexterously.O RunddichtringO 6 has also played the effect of sealing.Characteristics such as this device has simple in structure, and is reliable, easy to use.
