The single ball rolling-support rolling tool can meet the requirements of surface finish and geometric accuracy of the product design, has reliable performance and high quality, can improve the surface fatigue resistance of the product, prolongs the service life of the product, has easy manufacture and low cost, is applicable to rolling the outer diameter, inner holes, conical surfaces and complicated continuous transition surfaces of workpieces, has stronger practicality and is convenient to be popularized and applied in the industry.
Description
Technical field
The utility model belongs to the Machining Technology field, is specifically related to a kind of single pearl rolling and supports rolling tool.
Background technology
The processing of thin-wall bush product, all require very high to conical surface geometric accuracy and surface smoothness, traditional processing method adopts and improves metal cutting speed minimizing feed, and for the bigger workpiece of diameter, surpass 120 meters/minute cutting speed, vibrate very greatly, cause the cutting surface tool marks coarse, fineness is poor, can only reach
The fineness standard, i.e. new standard Ra10～5, this conventional method is unworkable, can not satisfy the designing requirement of product.
The utility model content
The utility model is in order to solve weak point of the prior art, provide a kind of simple in structure, machining accuracy is high, single pearl of easy operating rolls supports rolling tool.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: single pearl rolls and supports rolling tool, comprises knife bar, and described knife bar front portion vertically is provided with clamping hole, be provided with the ball base of column in the clamping hole, ball base one end is rotatably connected to the ball that protrudes from the knife bar surface.
The axial hollow-core construction of described ball base, radially be respectively equipped with strip hole and cylindrical hole, strip hole is vertical with cylindrical hole to be provided with, the axes intersect of the axis of strip hole, the axis of cylindrical hole and ball base is in a bit, be inserted with bearing pin in the strip hole, bearing pin is provided with bearing, ball base one end is bolted with limit screw cap, be provided with the back-up ring of internal diameter between ball base and the limit screw cap less than ball diameter, the corresponding circular hole that protrudes for ball that is provided with the back-up ring endoporus of limit screw cap, ball is located between the circular hole of bearing and limit screw cap.
Described knife bar vertically is provided with the elastic groove that is communicated with clamping hole together from front to back, and knife bar sidepiece level is provided with the screw that is connected with elastic groove, is bolted with bolt in the screw.
Adopt technique scheme, the thin-wall bush product is carried out rolling and processing (ELEMENTARY INTRODUCTION TO NON), promptly ball applies certain pressure to the processing work surface, makes surface of the work metal generation plastic deformation, thereby reaches the purpose that improves surface smoothness and hardness; By experiment, the utility model can satisfy the requirement of product design surface smoothness and geometric accuracy, dependable performance, the quality height, and improve product surface fatigue resistance, also corresponding increase in the service life of product, and be easy to make, with low cost, be applicable to roll extrusion workpiece external diameter, endoporus, conical surface and complicated continuous transition surface, have stronger practicality, be convenient in industry apply.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, single pearl of the present utility model rolls and supports rolling tool, comprise knife bar 1, knife bar 1 front portion vertically is provided with clamping hole 2, be provided with columned ball base 3 in the clamping hole 2, ball base 3 axial hollow-core constructions, radially be respectively equipped with strip hole 4 and cylindrical hole 5, strip hole 4 and cylindrical hole 5 vertical settings, the axis of strip hole 4, the axes intersect of the axis of cylindrical hole 5 and ball base 3 is inserted with bearing pin 6 in any in strip hole 4, bearing pin 6 is provided with bearing 7, strip hole 4 is used for bearing 7 is installed in ball base 3, and ball base 3 one ends are bolted with limit screw cap 8, are provided with back-up ring 9 between ball base 3 and the limit screw cap 8, limit screw cap 8 middle parts are provided with circular hole, be provided with ball 10 between bearing 7 and the limit screw cap 8, back-up ring 9 internal diameters are less than ball 10 diameters, and ball 10 protrudes from the circular hole at limit screw cap 8 middle parts.Knife bar 1 vertically is provided with the elastic groove 11 that is communicated with clamping hole 2 together from front to back, and knife bar 1 sidepiece level is provided with the screw 12 that is connected with elastic groove 11, is bolted with bolt 13 in the screw 12, and bolt 13 is used for clamping ball base.
When work is used, knife bar 1 is fixedly mounted on the lathe, ball 10 roll extrusion workpiece machining surfaces, workpiece rotate and drive ball 10 rotations, drive bearing 7 again and rotate.By a series of experiments, workpiece surface finish is before the roll extrusion
The fineness standard, i.e. new standard Ra10～5, fineness can reach after the roll extrusion
Be Ra1.25～0.6, thin hardened layer is 0.2～1mm, and case hardness improves 10～50%, and fatigue resistance improves 30～50%, especially for bearing the product of very big alternating force effect, improves 30～50% service life.In the roll extrusion process, the phenomenon of ball moment stall can not appear, be applied to cooling-lubricant in addition, very bright and clean attractive in appearance by rolling surface.
