Abstract
The invention discloses a pull rod type rolling mill which comprises an upper roller and a lower roller. The upper roller and the lower roller are located in the identical vertical plane, the two ends of the upper roller and the two ends of the lower roller are connected with upper bearing seats and lower bearing seats respectively through bearings, the two sides of the upper bearing seats and the two sides of the lower bearing seats are respectively and symmetrically provided with a pull rod, the two ends of the upper bearing seats and the two ends of the lower bearing seats are respectively and symmetrically provided with a mounting hole, a spherical pad is arranged in each mounting hole, a fixing threaded bushing is further arranged in each mounting hole, the pull rods are connected with the fixing threaded bushings in the mounting holes of the upper bearing seats of the same sides of the pull rods and the mounting holes of the lower bearing seats of the same sides of the pull rods, and one end face of each fixing threaded bushing is in spherical contact with one end face of the corresponding spherical pad. The pull rod type rolling mill is simple in structure, strong in stability, more reasonable and evener in stress and long in service life.
Description
Technical field
The present invention relates to a kind of rod-pulling type milling train.
Background technology
Milling train is the equipment of realizing metal rolled process, existing a kind of rod-pulling type milling train, utilize bearing block on pull bar, to move up and down the distance regulating between roll, on described pull bar fixing with left-right rotary to thread bush, in bearing block, be provided with adjusting pad, between adjusting pad and thread bush, be provided with adapter sleeve, thread bush, adapter sleeve and adjusting pad are plane contact and coordinate, when bearing block moves up and down on pull bar, adjusting pad and adapter sleeve can bear larger stress, and these stress directions can change always, because adjusting pad and adapter sleeve are that plane contact coordinates, cannot regulate according to stress direction, cause the Stress non-homogeneity being subject between adjusting pad and adapter sleeve, make the stability of milling train bad, and be subject to after Stress non-homogeneity, can not shorten the service life of milling train yet.
Summary of the invention
Goal of the invention of the present invention is: for the problem of above-mentioned existence, provide a kind of simple in structure, stability is better, stressed more reasonable, even, the rod-pulling type milling train of long service life.
The technical solution used in the present invention is such: a kind of rod-pulling type milling train, comprise topping roll and bottom roll, topping roll and bottom roll are in same perpendicular, described topping roll is connected by bearing with step with top chock respectively with bottom roll two ends, described top chock and step bilateral symmetry are provided with a pull bar, described top chock and step two ends are all symmetrically arranged with an installing hole, in described installing hole, be installed with a ball ring, in installing hole, be also provided with a retaining thread cover, pull bar is connected with retaining thread cover in the top chock of the same side and the installing hole of step, described retaining thread overlaps an end face and ball ring one end face is sphere-contact.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows:
1, simple in structure, stability is strong, more reasonable stress, even, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the local structure for amplifying schematic diagram in A place in Fig. 1.
Mark in figure: 1 is pull bar, 2, top chock, 3, topping roll, 4, bottom roll, 5, retaining thread cover, 6, ball ring, 7, installing hole, 8, step.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As Fig. 1, shown in Fig. 2, a kind of rod-pulling type milling train, comprise topping roll 3 and bottom roll 4, topping roll 3 and bottom roll 4 are in same perpendicular, described topping roll 3 is connected by bearing with step 8 with top chock 2 respectively with bottom roll 4 two ends, described top chock 2 and step 8 bilateral symmetry are provided with a pull bar 1, described top chock 2 and step 8 two ends are all symmetrically arranged with an installing hole 7, in described installing hole 7, be installed with a ball ring 6, in installing hole 7, be also provided with a retaining thread cover 5, pull bar 1 is connected with the top chock 2 of the same side and the interior retaining thread cover 5 of the installing hole 7 of step 8, described retaining thread cover 5 one end faces and ball ring 6 one end faces are sphere-contact.After adopting sphere-contact to coordinate, while being subject to different directions stress regulating the distance between roll, sphere coordinates can regulate the stress distribution of stress on thread bush and ball ring automatically, makes it stressed evenly reasonable, therefore also grow of the stability of milling train, and it is longer also to become service life.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
