Abstract
The invention discloses a rolling mill fork with a stress relief groove, which is used for solving the problem that the root of a slide block mounting groove of the existing rolling mill fork often cracks due to overlarge stress. Through designing a rolling mill jaw that tiger's mouth both sides have stress relief groove, characterized by stress relief groove and slider mounting groove lug connection, with the stress drainage of slider mounting groove to stress relief groove, reduce the stress of slider mounting groove to the life of extension rolling mill jaw.
Description
Technical Field
The invention relates to the field of metallurgical equipment, in particular to a rolling mill fork with a stress release groove.
Background
The rolling mill fork head is the important part of bearing of connecting motor and rolling mill flat head, and in rolling process, the rolling mill fork head bears great load, leads to its inside slider mounting groove position stress great, and the problem of ftractureing often appears at rolling mill fork head slider mounting groove root under the effect of long-term alternating load, seriously influences production operation safety.
Disclosure of Invention
In order to overcome the problems, the invention provides a rolling mill fork with a stress release groove, and aims to solve the problem that the root of a slide block mounting groove of the existing rolling mill fork often cracks due to overlarge stress.
In order to achieve the purpose, the invention adopts the following technical scheme from the structural characteristics of the slide block mounting groove: the rolling mill fork head with the stress release groove on the outer side of the tiger's mouth is designed, and the stress of the sliding block mounting groove is guided to the stress release groove.
The invention has the beneficial effects that: because the stress relief grooves are formed in the two sides of the jaw of the rolling mill jaw, the concentrated stress of the sliding block mounting groove can be guided to the stress relief grooves, so that the stress of the sliding block mounting groove is reduced, the torque bearing capacity of the jaw is greatly improved, and the service life of the rolling mill jaw is prolonged.
Drawings
FIG. 1 is a three-dimensional schematic view of the structure of the present invention.
Detailed Description
The invention will be further explained with reference to the drawings.
Fig. 1 is a three-dimensional schematic diagram of the structure of the invention, and the rolling mill fork is of a symmetrical structure and is specifically characterized by comprising a rolling mill connecting end 1, a middle part 2 and a motor connecting end 3. The rolling mill connecting end 1 is internally provided with a tiger's mouth which consists of an inner arc surface 4, an outer arc surface 5, a sliding block mounting groove 6, a stress release groove 7 and an oil hole 8. The slider mounting groove 6 inlays in the middle part of outer arc surface 5, and stress release groove 7 inlays in the 4 outsides of interior arc surface, and stress release groove 7's bottom surface be with the endocentric arc surface of interior arc surface 4, stress release groove 7 and slider mounting groove 6 lug connection, oilhole 8 intercommunication to motor connection end 3.
Claims (4)
1. A rolling mill jaw with stress release grooves is characterized in that two sides of a jaw opening of the jaw are respectively provided with one stress release groove.
2. The rolling mill yoke with stress relieving grooves as claimed in claim 1, wherein the rolling mill yoke has two stress relieving grooves in total and is symmetrically distributed.
3. The rolling mill jaw with the stress relief groove of claim 1, wherein the stress relief groove bottom surface of the rolling mill jaw is a curved surface or a flat surface.
4. The mill jaw with the stress relief groove of claim 1, wherein the stress relief groove of the mill jaw is directly connected to the slider mounting groove.
