Abstract
The utility model relates to an elastic-plane hardening roller press, which belongs to the technical field of the metal mechanical process. The traditional plane roller press has no elastic structure, the processing is rigid, and the workpiece surface is easy to generate the defects of pit, peeling, etc. The purpose of the utility model is to design a novel elastic roller press to eliminate the processing defects. The lower end of the roller press is provided with a rolling wheel by using a connecting piece, the upper end is provided with a gasket, a spring, nuts, etc. by using a threaded core shaft, and the roller press force can be automatically adjusted in the processing. Therefore, the elastic processing of the plane roller press is realized, the defects of pit, peeling, etc. are eliminated, and the structure is simple.
Description
Title of the present utility model is an elastic linear hard rolling device, belongs to the metal machining technical field.
Traditional nonelastic structure of plane roll extrusion utensil, can only carry out the rigidity rolling and processing to workpiece planarization, in process, can not adjust automatically, easily make surface of the work produce defectives such as " pit ", " peeling ", and the impact phenomenon can produce the lathe feed time, have a strong impact on crudy.
The purpose of this utility model is a kind of novel stitching of design, has elastic construction, make processing become the elasticity roll extrusion from the rigidity roll extrusion, realize the adjustment voluntarily of pair of rollers surface of the work pressure, improve crudy, eliminate defectives such as " pit ", " peeling ", produce impulsive force in the time of also can not making the lathe feed.
The utility model profile and structure are as shown in drawings.It is made of several critical pieces such as gripper shoe (1), roller (2), connecting plate (3), spring assembly.Gripper shoe placed in the middle (1), cross sectional shape is a rectangle, top is straight, lower tilt, below sloping portion be provided with a cylindrical hole; Connecting plate (3) is a dihedral, the upper end is provided with a cylindrical hole (12), on the width of base, open one " U " shape groove, and on two sides, being provided with two cylindrical holes (13,14), gripper shoe (1) lower tilt is partly inserted in the U-lag of connecting plate (3) middle part and by axle (5) and is connected with connecting plate; Roller (2) is connected with connecting plate (3) by axle (6), and it can rotate freely around axle (6); Spring (4), packing ring (9), spheric washer (10) nut (8) fit together by threaded mandrel (7) and connecting plate (3).
The upper end of gripper shoe (1) is connected with employed lathe (generally being planer), by adjusting the vertical feed of lathe, the roller of this device is contacted, with workpiece planarization when the lathe long feed (promptly installs synchronously with this, rectilinear motion) after, promptly realized of the roll extrusion of this device to workpiece planarization.Owing to can adjust the pressure and the elasticity of spring (4) by turning nut (8), thereby adjust the pressure of pair of rollers surface of the work, realize the elasticity roll extrusion.The diameter of roller and width are decided with the size of workpiece planarization, and dimensions commonly used is φ 50～90 * 20～40mm, and common used material is alloy tool steel 5CrMnMo or T10A, quenching hardness HRC54～58.
The utility model has been realized the processing to the roll extrusion of surface of the work elasticity, the pair of rollers surface of the work has remained the elastic tight contact, itself also rotates roller, thereby can not make surface of the work produce " pit ", " peeling " phenomenon, overcome the shortcoming of conventional rigid plane roll extrusion, improved crudy.After the elasticity rolling and processing, initial roughness Ra8.0～2.0 of surface of the work before the roll extrusion are reduced to Ra1.0～2.0, and promptly surface roughness has reduced by 3～4 grades (surface smoothness has improved 3～4 grades).Simultaneously, obviously improved hardness and wearability, fatigue resistance and the service life of surface of the work, production efficiency also can improve 1～2 times, and effect is fine.This device can be widely used in the metal machining industry.
