Embodiment Construction

[0018] In order to clearly illustrate the technical features of the solution, the solution will be described below through specific implementation modes.

[0019] Such as Figure 1~3 As shown, a short stress line rolling mill depressing nut fixing structure of the present invention includes a bearing seat 5, a pull rod 1 passing through the bearing pedestal 5, and a depressing nut 3 threaded on the pull rod 1, and the pull rod 1 is equipped with The spherical pad 2 located below the depressing nut 3 is provided with a spherical surface corresponding to the spherical pad 2 on the lower end surface of the depressing nut 3 .

[0020] The bearing seat 5 is provided with a counterbore adapted to the depressing nut 3, and the depressing nut 3 compresses the spherical pad 2 at the bottom of the counterbore.

[0021] It also includes a positioning sleeve 9 set on the pull rod 1, the positioning sleeve 9 is located above the pressed nut 3 and fixedly connected with the bearing seat 5,...

Abstract

The invention relates to a screw box fixing structure of a short-stress-path rolling mill. The screw box fixing structure comprises a bearing pedestal, a pull rod penetrating through the bearing pedestal and a screw box in threaded connection with the pull rod. A counter bore matched with the screw box is formed in the bearing pedestal. The screw box fixing structure further comprises a positioning sleeve arranged on the pull rod in a sleeving mode. The positioning sleeve is located above the screw box and fixedly connected with the bearing pedestal. The pull rod is in threaded connection with a balance nut supporting the positioning sleeve. The balance nut is located between the positioning sleeve and the screw box. A plurality of rotation stopping protrusions are fixedly connected to the lower end of the positioning sleeve. A notch A allowing the rotation stopping protrusions to penetrate through is formed in the balance nut. A notch B allowing the rotation stopping protrusions to be inserted therein is formed in the upper end of the screw box. The screw box fixing structure is fast to install and adjust and high in strength, a structure and a connecting piece for preventing relative rotation between the balance nut and the screw box are omitted, stable and enough rotation stopping force can be provided, it is guaranteed that the rolling mill keeps the balance effect, and the equipment performance of the short-stress-path rolling mill can be stably exerted for a long time.

Description

technical field [0001] The invention relates to the field of short stress line rolling mills, in particular to a short stress line rolling mill depressing nut fixing structure. Background technique [0002] The depressing nut is an important part of the short stress line rolling mill. Under normal circumstances, it fits closely with the spherical pad installed on the bearing seat and cannot rotate with the pull rod. It is stationary relative to the bearing seat. Relevant measures are required to restrict it. The depressing nut rotates together with the pull rod. The common method is to set external teeth on the outer circumference of the depressing nut, and use a piece of anti-rotation pin teeth arranged on the side of the bearing seat to insert between the two teeth to complete the anti-rotation. However, in the actual use process, this structure has low strength, and it is often damaged and loses the ability to stop the rotation. The nut is pressed and loosened, causing th...
