Description
Technical field
The present invention relates to the adjustable rolling tool of a kind of self-lubricating pressure, particularly a kind of steel ball and macromolecular material of adopting, as the self-lubricating rolling tool of roll extrusion part, belongs to machining Treatment of Metal Surface cutter manufacturing technology field.
Background technology
Rolling tool of the prior art, biases toward the roller tumbling of bearings, without the hard extruding of the jewel cutter of tourelle, or adopts high-pressure oil pump to produce the hard pressurizing unit of high pressure.As CN202825498U discloses a kind of polishing wheel that adopts bearing chamber to support, bearing chamber is also provided with oily window, air bleeding valve, fuel outlet etc. for lubricating bearings, guarantees in machine high-precision work at normal temperatures.Its problem is that complex structure cost is high, and must be with the oil that can pollute or grease as lubricant, or with oil plant, is converted to high pressure and pushes polishing.
The present invention has overcome the shortcoming being showed with upper type structure at all, by simple and effective structure, arranges, and simplifies rolling tool, reduces the cost of rolling tool manufacture and replacing, and exempts the use of lubricating oil, avoids environmental pollution.
Summary of the invention
The technical solution that realizes above-mentioned purpose is: the adjustable rolling tool of a kind of self-lubricating pressure, comprise that ball retainer, self-lubricating push away core, steel ball, spring and pressure screw bolt, wherein ball retainer is contained in the hollow cavity of cutter hub, and is fixed on cutter hub by being looped around the flange of ball retainer; Steel ball is contained in ball retainer, and be arranged on ball retainer foremost, outward opening foremost by ball retainer stretches out, with contact workpiece, realize the effect of tumbling, the part that the external diameter of steel ball is set to steel ball exposes to outside the opening of ball retainer, but the size of opening is less than the diameter of steel ball, steel ball can not drop out ball retainer from opening; Self-lubricating pushes away core and is also contained in ball retainer inside, near and withstand steel ball; Spring supporting is between ball retainer and pressure screw bolt, and pressure screw bolt is fixed on the afterbody of cutter hub; Pressure screw bolt can tighten up spring by cutter hub tailing screw flight and produce thrust.Oil-free lubrication simple in structure, when steel ball is according to regulating pressure to withstand on surface of the work, and with the reverse high speed rotating of rotation direction of workpiece, and by pressure and ball self fineness, workpiece is carried out to tumbling, result can reach minute surface.Pressure screw bolt produces and screws forward the effect of the pressure that unscrews backward and produce according to cutter hub internal thread, thereby has regulated thrust size, makes it different materials have the selection of thrust.Can regulate the position of pressure screw bolt in cutter hub by the described pressure screw bolt on rotation cutter hub internal thread, thereby regulate the size of pressure screw bolt to spring thrust.Different coefficients of friction by steel ball in rolled material and macromolecular material, under uniform pressure, frictional force is different, thereby makes steel ball rolling.Due to pressure-acting, make machined material reach the effect of tumbling.
Rolling tool of the present invention, with respect to prior art, has the following advantages:
1, under any cooling fluid condition, self-lubricating reaches the object of roll extrusion;
2, do not use lubricated oil or grease;
3, simple in structure, can be directly installed on standard cutter hub;
4, the cost of operation and maintenance significantly declines.
Accompanying drawing explanation
Accompanying drawing 1 is the main perspective schematic diagram of rolling tool of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, rolling tool of the present invention can be contained on standard-sized cutter hub 1, it comprises that ball retainer 2, self-lubricating push away core 3, steel ball 4, spring 5 and pressure screw bolt 6, wherein ball retainer 2 is contained in the hollow cavity of cutter hub 1, and is fixed on cutter hub 1 by being looped around the flange of ball retainer 2; Steel ball 4 is contained in ball retainer 2, and be arranged on ball retainer 2 foremost, outward opening foremost by ball retainer 2 stretches out, with contact workpiece, realize the effect of tumbling, the part that the external diameter of steel ball 4 is set to steel ball 4 exposes to outside the opening of ball retainer 2, but the size of opening is less than the diameter of steel ball 4, steel ball 4 can not drop out ball retainer 2 from opening; Self-lubricating pushes away core 3 and is also contained in ball retainer 2 inside, near and withstand steel ball 4; Spring 5 is supported between ball retainer 2 and pressure screw bolt 6, and pressure screw bolt 6 is fixed on the afterbody of cutter hub 1; Pressure screw bolt 6 can tighten up spring 5 by cutter hub tailing screw flight and produce thrust.Oil-free lubrication simple in structure, when steel ball is according to regulating pressure to withstand on surface of the work, and with the reverse high speed rotating of rotation direction of workpiece, and by steel ball the different coefficients of friction in rolled material and macromolecular material, under uniform pressure, frictional force is different, thereby makes steel ball rolling.Due to pressure-acting, make machined material reach the effect of tumbling, pressure and ball self fineness is carried out tumbling to workpiece, and result can reach minute surface.Pressure screw bolt 6 produces and screws forward the effect of the pressure that unscrews backward and produce according to cutter hub internal thread, thereby has regulated thrust size, makes it different materials have the selection of thrust.Can, by the described pressure screw bolt on rotation cutter hub internal thread, regulate the position of pressure screw bolt 6 in cutter hub 1, thereby regulate the size of 6 pairs of spring thrusts of pressure screw bolt.
The present invention, under the condition enabling without the external world, produces thrust by self structure, and cutter can rotate freely on knife rest, and the processing beat of product shortens, and does not need clamping workpiece again, and precision, efficiency significantly improve.Without external power source, produce pressure, do not need oil pump, therefore without peripheral facility, provide the energy.
Mode is in the past when steel ball rolling, to need grease lubrication auxiliary, reduces coefficient of friction, and under uniform pressure, frictional force diminishes, so heat loss is also just less.It is to have adopted high molecular abrasion-proof material that self-lubricating of the present invention pushes away core, and high temperature resistant, is furnished with best bright finish steel ball, form self-lubricating condition, utilize workpiece and macromolecular material to steel ball under uniform pressure, coefficient of friction is different and frictional force is different, and steel ball is rotated.Thereby removed grease and the lubricating oil polluting, also reduced the cost of design, manufacture, fuel consumption.
Rolling tool of the present invention can be arranged on the cutter hub of standard, and easy for installation, the scope of application is wide, and the cost of replacing steel ball is low, has greatly reduced operation and maintenance cost.Without additional source of energy, produce thrust, accomplishing both energy-conservationly has an environmental protection.
Above-mentioned specific embodiment is described by example, should be understood that, these embodiment are subject to the impact of different distortion and optional form.It should also be further understood that, claim is not meaned and is limited to disclosed particular form, and should cover all distortion, the equivalence that drop in essence of the present invention and scope, replaces and optional mode.
