Abstract
The invention, which belongs to the technical field of the machining tool, provides a rotatable multi-roller-pin forming rolling knife comprising roller pins, a holding frame, a drive shaft, a deep groove ball bearing, a transmission gear, a set screw, a clamp ring, a hexagonal nut, a bolt group, a conical block, a pressing block, and a round flat key and the like. The rolling knife is driven by the transmission gear based on power to make rotation; and the roller pins are fixed at the inside the roller knife by the pressing block and the conical block. Three pairs of roller pins of the knife head are perpendicular to each other and are arranged in a staggered mode. The rolling knife has the following advantages: the right-angle part of a workpiece can be rolled at one procedure, thereby improving the rolling efficiency obviously. Because the roller knife can be driven by the gear to make rotation, both a rotatable workpiece and a workpiece that can not be rotated easily can be rolled.
Description
Technical field
The present invention relates to the technical field of machine tool, particularly, relate to a kind of rotatable many needle rollers shaping rolling depression cutter.
Background technology
Rolling depression cutter utilizes the plastic deformation of metal, and the microcosmic planishing surface of the work is uneven, thus reaches the object changing surface structure, mechanical property, shape and size.No matter with which kind of process tool processing parts, always fine scraggly tool marks are left at piece surface, occur the staggered peak valley phenomenon risen and fallen, roll extrusion is the principle utilizing mechanical presses, obtains a kind of machinery of the bright and clean metal surface as mirror without the plastic processing method cut.In addition, roll extrusion is also widely used in welding position, is improved the effect such as the compression of surface of the work, refinement surface of the work crystallite dimension.
In recent years, rolling tool gets a larger development, but rolling depression cutter conventional is at present mainly used in the position of the easy roll extrusion such as roll extrusion plane, the surface of revolution, for position, workpiece right angle, special cutter is not also had to carry out roll extrusion, although utilize milled head, rolling wheel etc. can carry out roll extrusion to the workpiece rotated, but roll extrusion efficiency is lower, a workpiece right angle needs repeatedly roll extrusion, and for the workpiece being difficult to rotate, then cannot roll extrusion.So design a kind of not only can roll extrusion rotational workpieces but also efficient, the Special rolling cutter of roll extrusion fixation workpiece can seem particularly necessary.
Summary of the invention
Problem to be solved by this invention is the deficiency existed for prior art, designs a kind of rotatable many needle rollers shaping rolling depression cutter.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of rotatable many needle rollers shaping rolling depression cutter, structure mainly comprises needle roller, retainer, power transmission shaft, deep groove ball bearing, travelling gear, holding screw, collar, hex nut, hex bolts group, circular cone, briquetting, round end flat key, it is characterized in that: travelling gear is connected with power transmission shaft by round end flat key, collar is arranged on the left side of described travelling gear, holding screw is arranged on described collar, described collar and described holding screw coordinate fixed conveyor gear, deep groove ball bearing is arranged on power transmission shaft, lathe can be clamped in the outer shroud of described deep groove ball bearing, rolling depression cutter can be fixed, do not affect again described rolling depression cutter to rotate, needle roller is arranged in the needle roller groove in retainer, respectively there are three needle rollers described retainer both sides, three needle rollers are uniformly distributed retainer surface, described briquetting is pressed with on described needle roller, circular cone is pressed in above described briquetting, fastening by hex bolts group, has keyway above described circular cone, be connected with power transmission shaft by round end flat key, described power transmission shaft is connected by hex nut with described retainer.
Below technical scheme of the present invention is described further.
Aforesaid one rotatable many needle rollers shaping rolling depression cutter, it is characterized in that, respectively there are three needle rollers retainer both sides, and are uniformly distributed, three pairs of needle rollers are vertically interlaced between two.
Aforesaid one rotatable many needle rollers shaping rolling depression cutter, is characterized in that, regulated the degree of tightness of circular cone by bolt, adjustable needle roller is to surface of the work pressure.
Aforesaid one rotatable many needle rollers shaping rolling depression cutter, is characterized in that, machine power, by gears meshing, can, power transmission to the power transmission shaft of rolling depression cutter, drive rolling depression cutter to rotate.
Usefulness of the present invention is: one of the present invention rotatable many needle rollers shaping rolling depression cutter adopts many needle rollers to design, three pairs of needle rollers are vertical between two, and are interspersed, can to the direct roll extrusion in position, workpiece right angle, a roll extrusion can cover whole right angle, improves roll extrusion efficiency; The present invention rotates by gear driven cutter head, not only can the rotatable workpiece of roll extrusion, for the workpiece being difficult to rotate, equally can roll extrusion, and improve roll extrusion scope; The degree of tightness of needle roller, can be realized by fastening bolt, easy to adjust.

Detailed description of the invention
In order to make technical problem solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
A kind of rotatable many needle rollers shaping rolling depression cutter, structure mainly comprises 1 needle roller, 2 retainers, 3 power transmission shafts, 4 deep groove ball bearings, 5 travelling gears, 6 holding screws, 7 collars, 8 hex nuts, 9 hex bolts groups, 10 circular cones, 11 briquettings, 12 round end flat keys.Travelling gear 5 is connected with power transmission shaft 3 by round end flat key 12, machine power drives rolling depression cutter to rotate by travelling gear 5, collar 7 is arranged on the left side of travelling gear 5, holding screw 6 is arranged on described collar 7, described collar 7 and described holding screw 6 coordinate fixed conveyor gear 5, and deep groove ball bearing 4 is arranged on power transmission shaft 3, and lathe can be clamped in the outer shroud of described deep groove ball bearing 4, can rolling depression cutter be fixed, not affect again described rolling depression cutter and rotate; 1 needle roller is arranged in the needle roller groove in retainer 2, described needle roller 1 is pressed with described briquetting 11 above, circular cone 10 is pressed in above described briquetting 11, fastening by hex bolts group 9, described circular cone 10 has keyway above, be connected with power transmission shaft 3 by round end flat key 12, described power transmission shaft 3 is connected by described hex nut 8 with described retainer 2.
During work, machine tool chief axis etc. are rotated by gear driven rolling depression cutter, and rolling depression cutter is slowly near the right angle portions needing roll extrusion, as shown in Figure 1, needle roller is pressed in position, right angle with suitable pressure, carries out roll extrusion to right angle, if pressure is too large, adjustable hex bolts group 9, suitably unscrews, then needle roller can reduce the pressure of workpiece, after roll extrusion completes, close lathe, remove rolling depression cutter, complete rolling process.
