Abstract
The utility model discloses a sliding block device of a cantilever type universal spindle bracket with an improved structure. The device consists of a corbel, a sliding block body, compression springs, a spring seat and a locking nut, wherein a gap is arranged between the sliding block body and the corbel to provide a buffering position horizontally in the radial direction, an inner compression spring is arranged in the sliding block body, and an outer compression spring is arranged on the sliding block body. A wear-resisting bush is arranged between the corbel and the sliding block, the outer spring is provided with the spring seat, and the spring seat is adjusted and locked by the locking nut. The device disclosed by the utility model is reasonable in design, has a simple structure, and is convenient to adjust and use, the radial horizontal jumpiness produced by the high-speed rotation of a universal spindle is reduced or eliminated, the service life of the device is prolonged, and the quality of rolled products is stable.
Description
Technical field
The utility model belongs to the steel rolling equipment technical field, is specifically related to high rotating speed, scalable universal-joint spindle cantilevered bracket slide block device that milling train main frame row constant speed gear-box connects with roll.
Background technology
In the full continuous rolling production line of shaped steel, generally all adopt universal-joint spindle to connect between the constant speed case of milling train main frame row and the roll.Because mill speed is higher, the K of medium shape tandem rolling line
1Linear velocity can reach 13.6m/s, and the milling train requirement is traversing, after being convenient to change pass, can guarantee online all design of section of rolling mill point-blank, and favourable Rolling Production is smooth, is difficult for badly bleeding; When reaching roll change, roller system can whole release carry out integral replacing, save time.Therefore universal-joint spindle must select extension type (± 300mm).Universal-joint spindle will inevitably produce stronger acutely beating when high rotating speed rotation.The slide block device of intrinsic universal-joint spindle cantilever bracket is beated and is had the critical defect (see figure 3) overcoming the radial level direction, only at trailing arm 10 and slide block 11 in-built one group of butterfly spring 13, make trailing arm, slide block become a rigid body after installing with locking nut 12, horizontal direction is nonelastic buffering leeway, cause whole cantilever bracket acutely to swing during the universal-joint spindle High Rotation Speed, 6 M48 foundation bolts all can't be fixed, and can not use at all.
Summary of the invention
The purpose of this utility model provides a kind of cantilevered universal spindle carrier slide block device that improves structure, this device can make steel rolling main frame row universal-joint spindle cantilevered bracket held stationary when High Rotation Speed, reducing radial level beats, improve service life of equipment, guarantee rolling constant product quality.
For achieving the above object, the technical solution adopted in the utility model is: a kind of cantilevered universal spindle carrier slide block device that improves structure is comprised of trailing arm, slide block body, Compress Spring, spring base and locking nut.Be characterized between slide block body and the trailing arm certain interval being set, make radial level that buffer position be arranged, an interior Compress Spring is installed in the slide block body, this externally refills an external compression spring slide block.Between trailing arm and the slide block anti-wearing liner is housed, outer spring is equipped with spring base, and locks with the locking nut adjustment.
Description of drawings
Fig. 1 is the structural representation that the utility model improves the cantilevered universal spindle carrier slide block device of structure.
Fig. 2 is partial schematic sectional view of the present utility model.
Fig. 3 is former cantilevered universal spindle carrier slide block device structural representation.
The specific embodiment
As depicted in figs. 1 and 2, the cantilevered universal spindle carrier slide block device of the utility model improvement structure is comprised of trailing arm 1, slide block body 2, interior Compress Spring 3, external compression spring 4, spring base 5 and locking nut 6.
Described slide block body 2 length reduce 10mm, make and form buffer gap 9 between slide block body 2 and the trailing arm.
Between described trailing arm 1 and the slide block body 2 anti-wearing liner 7,8 is housed.
The utility model is reasonable in design, and is simple in structure, adjusts easy to usely, reduced or eliminated the radial level that produces because of the universal-joint spindle High Rotation Speed and beated, and prolonged service life of equipment, guaranteed the steady quality of rolled products, is worthy of popularization.
