Embodiment Construction

[0030] The present invention utilizes the tangential equal-curvature bending processing equipment in the process of producing lining rings from steel strips, including vertical plate base (1), pinch roller I (16), pinch roller II (21), pinch roller III (31), driven by a motor Driven round rod (2). The vertical board seat (1) is installed on a horizontal plane by a fixture. The round rod (2) is vertically installed on the vertical plate base (1) by the bearing seat, with an annular straight tooth on it. The annular straight teeth are used to drive the wound steel belt (4) to move forward. Each pinch roller is installed on the vertical plate seat (1) by the fixing mechanism in the vertical plane with its own circular side, and is respectively located at three places around the periphery of the round rod (2); the improvement of the present invention is:

[0031] (a) The annular straight teeth on the round rod (2) are located in the annular groove around the round rod, and the d...

Abstract

The invention relates to tangential iso-curvature bending equipment in the process for producing a backing ring by utilizing a steel strip, which is applied to tangential iso-curvature bending of the steel strip subjected to coarse and fine die rolling in the process for producing the backing ring by utilizing the steel strip so as to wind the steel strip into a ring. The equipment comprises a vertical plate seat, a pressing wheel I, a pressing wheel II, a pressing wheel III and a circling rod driven by a motor, wherein the circling rod is vertically installed on the vertical plate base via a bearing seat. The equipment is characterized in that (a) a ring-shaped straight tooth on the circling rod is arranged in a ring-shaped groove of the circling rod and the groove depth is 1-2mm; (b) the rims of the pressing wheel I and pressing wheel II are provided with grooves; and (c) the pressing wheel I, the pressing wheel II and the pressing wheel III are respectively installed on the vertical plate seat via three combination mechanisms formed by screw rod adjusting slider mechanisms and screw rod adjusting slider seat mechanisms thereof. The equipment has the following advantages that: 1. the adjusting process is simple and flatness control is stable; 2. operation is stable, the daily production capacity is high and the production cycle is shortened by more than 40% compared with the existing production period; and 3. the varieties with different ring radii can be produced by the same equipment.

Description

technical field [0001] The invention relates to tangential equal-curvature bending processing equipment in the process of producing lining rings by using steel strips, which is applied to tangentially equal-curvature bending the steel strips after rough and fine mold rolling processes in the process of producing lining rings by using steel strips. Wrap into a ring. Background technique [0002] The backing ring and scraper ring are combined to form a combined oil ring for installation on the piston. The structure of this combined oil ring is that two scraper rings are respectively located on the shoulders on both sides of the backing ring. In the combined structure, the function of the backing ring is to support the wiper ring from both radial and axial directions, and the key is to provide a certain amount of radial elastic force to the wiper ring. [0003] The current H-shaped lining ring, also known as the Great Wall-shaped lining ring, corrugated lining ring, which is a...
