Abstract

The invention discloses an axial float limiting device of a short stress trajectory rod mill, and has the advantage that the product quality can be improved. The axial float limiting device of the short stress trajectory rod mill comprises a base seat and a rolling mill body, an axle bearing seat of a built-in bearing which is matched with the roller is arranged on the rolling mill body, a stop device is respectively arranged at the both ends of the roller, and the stop device is fixed and connected with the base seat. The roller can be fixed on the axial direction through leading the stop device to be respectively arranged at the both ends of the roller and the stop device to be fixed and connected with the base seat, the steel floating is avoided during rolling, thereby the potentiality of danger during rolling can be avoided, the rolled steel product quality can be effectively improved, and the axial float limiting device is suitable to popularize in the small norm short stress trajectory rod mill.

Description

The axial float device for limiting of short-stress path bar mill

Technical field

The present invention relates to a kind of fixture, especially relate to a kind of axial float device for limiting of short-stress path bar mill.

Background technology

At present, that milling train on the modernization rolling bar line is generally is flat, grade separation is for arranging, the body part of flat, vertical mill is except the placement direction difference, its structure and size are identical, body part promptly flat, vertical mill can exchange fully, and the just vertical miller that goes wrong, its structure is as shown in Figure 1, body directly drops on the base, and the upper and lower working roll roller in the body is that fixture is not set vertically.Because the cumulative errors that work in-process exists, when installing, there is the fit-up gap between its each assembly parts, in addition, after long-term the use, wear and tear between each moving component, make that when rolling bar the upper and lower working roll roller in the body is that play takes place vertically, and following critical defect occurs: jump steel during steel rolling easily, the red steel bar of jumping out is owing to speed height, inertia are big, so dangerous big; Rolling rod product circularity of coming out is poor.

Summary of the invention

Technical problem to be solved by this invention provides a kind of axial float device for limiting of the short-stress path bar mill that improves the quality of products.

The technical solution adopted for the present invention to solve the technical problems is: the axial float device for limiting of short-stress path bar mill, comprise base and milling train body, on the milling train body, be installed with the bearing block of the built-in bearing that cooperates with roll, be provided with stopping means at the roll two ends, stopping means is fixedly connected on the base.Stopping means is set and stopping means is fixedly connected on the base by two ends, make roll to be lived at axial restraint, avoid when rolling, jumping steel at roll, thus causing danger property can avoid steel rolling the time, and can effectively improve the rolling steel product quality that comes out.

As the preferred version of technique scheme, stopping means is a baffle plate.

Further be, described baffle plate is four, and four baffle plates are separately positioned on the bearing block outer face at roll two ends and are positioned at the axis both sides of roll.

Further be that baffle plate is provided with and the suitable gathering sill of milling train body.

The invention has the beneficial effects as follows, stopping means is set, make and roll can be lived at axial restraint, avoid when rolling, jumping steel by two ends at roll, thus causing danger property can avoid steel rolling the time, and can effectively improve the rolling steel product quality that comes out.Be particularly useful for promoting the use of above the small dimension short-stress path bar mill.

The specific embodiment

The present invention is further described below in conjunction with drawings and Examples.

As Fig. 2～shown in Figure 7, the axial float device for limiting of short-stress path bar mill of the present invention, comprise base 1 and milling train body 2, on milling train body 2, be installed with the bearing block 3 of the built-in bearing that cooperates with roll 4, be provided with stopping means 5 at roll 4 two ends, stopping means 5 is fixedly connected on the base 1.Stopping means 5 is set and stopping means 5 is fixedly connected on the base 1 by two ends at roll 4, make and roll 4 can be lived at axial restraint, avoid when rolling jumping steel, thus causing danger property can avoid steel rolling the time, and can effectively improve the rolling steel product quality that comes out.

In the above-described embodiment, described stopping means 5 can be the versions such as fixedly end cap that are arranged at the roll two ends, and as preferred embodiment, stopping means 5 is a baffle plate.By stopping means 5 is set to baffle plate, its processing and manufacturing is simple, and installs easily, makes can realize roll 4 is fixed along axis direction by low cost.Baffle plate can be arranged at the first-class place that can limit roll 4 along the axis direction play of end face of roll 4, as preferred embodiment, described baffle plate is four, and four baffle plates are separately positioned on bearing block 3 outer faces at roll 4 two ends and are positioned at the axis both sides of roll 4.At the two ends of roll 4 two baffle plates are set respectively, and the baffle plate of every end is arranged on the both sides of roll 4, the inner surface of baffle plate fixedly is loaded on the outer face of bearing block 3, can avoids roll 4 that play takes place in the process of rolled steel vertically effectively by bearing block 3 is in axial direction fixed like this.

In order to make the milling train body 2 can be up and down along the installation direction of baffle plate, baffle plate be provided with the gathering sill 6 suitable with milling train body 2.Just make milling train body 2 to be installed on the base 1 along gathering sill 6, and make in rolling like this, milling train body 2 can slide along gathering sill 6, also can limit roll 4 simultaneously well along the axis direction play.
