Abstract
The utility model discloses a rolling tool. A spiral spring between an ejector rod and a plug screw rod is pressed in a cavity of a tool body. According to machining needs, the plug screw rod is screwed to adjust the pressure of the spring on the ejector rod and a ball bearing, and indicating value marks are engraved on the cylindrical part of the plug screw rod, so that the pressure values generated by the spring on the ball bearing under different compression degrees can be indicated.
Description
Technical field
The utility model relates to a kind of rolling tools, belongs to metal machining tool technology, specifically is meant a kind of being used for above the lathe, rotational workpieces is carried out a kind of instrument of Surface Machining.
Background technology
At present, on lathe, rotational workpieces being carried out the rolling tools of Surface Machining, all is the rolling tools of rigidity generally; When the roll extrusion workpiece, there is the relatively poor and uneven defective of surface smoothness in the rolling tools of this rigidity; Because active force is compulsory, also there is the uneven defective of surperficial flow harden of being processed, in addition; Before roll extrusion, also higher to the requirement of last process, there is the higher defective of technology cost.
Summary of the invention
The purpose of the utility model is: a kind of rolling tools are provided, overcome the existing existing above-mentioned defective of rolling tools.
The utility model realizes that the technical scheme that above-mentioned purpose adopted is: this utility model comprises ball, case, bearing pin, lock nut, ball bearing, bearing support, swivel nut, push rod, spring, backstay, plug screw bar; On the ball bearing external diameter surface of state monopoly for marketing axle rotation, be provided with ball bearing; The ball outside is covered with bronze case; Screw thread coupling mutually between bronze case and the bearing support; Ball fixedly is rotationally connected through lock nut in bronze case centre bore, in bearing support, swivel nut, push rod are screwed into the body of rolling tools, forms fluid head.In the tool body chamber, be pressed with the helical spring between top cup and the plug screw bar.According to the processing needs, turn the plug screw bar, to the pressure of push rod and ball, be carved with indicating line with the adjustment spring at the column part of plug screw bar, with show spring under various different compression degrees to force value that ball was produced.
Beneficial effect: the rolling tools of the utility model, the power that makes metal produce plastic deformation is come spring.Therefore, the flow harden of surface of the work and surface smoothness are more even.And it does not resemble then the property rolling and processing strict to the processing request of workpiece preceding working procedure yet.Have surface smoothness better and advantage of uniform because active force is not compulsory, the surperficial flow harden of being processed evenly in addition, before roll extrusion, also not high to the requirement of last process, the technology cost is lower.
