The extension of the extension of handle of a knife contiguous block 2 and cutter connecting cylinder 7 has the bolt hole of working in coordination, and they can be linked together by hexagon-headed bolt and hex nut, indirectly shank portion and cutter body is linked together.
Described ball assembly comprises supporting base 8, ball 9 and retainer 10, and described retainer 10 is fixed on the bottom of described supporting base 8, and described ball 9 is arranged in retainer 10. On described retainer 10, there are multiple spherical pores, multiple described balls 9 can be installed, further reduce machined surface roughness and significantly promote working (machining) efficiency. Described ball 9 can be selected sintered carbide ball or Ceramic Balls, realizes the workpiece of different hardness is processed, and expands processing object scope.
1 one-tenth cone shape of described handle of a knife, center, upper end has screwed hole, can be by the main shaft of the equipment such as milling machine institute clamping. Handle of a knife 1 and handle of a knife contiguous block 2 have guide frame, are convenient to keyway and each screwed hole location. Handle of a knife 1 is connected by upright soket head cap screw with handle of a knife contiguous block 2.
The exterior portion of described cutter body is cutter connecting cylinder 7, and the inside part is respectively force bearing plate 3, power sensor 4, sensor holder 5, excellent power glue 6, ball bearing seat 8, ball 9, retainer 10 from top to bottom. Cutter is pressing down in process, and workpiece transmits from bottom to top to the active force of cutter, so in order to describe more accurately, more easily cutter, the description of cutter body is also adopted to mode from bottom to top.
Described supporting base 8 and retainer 10 have spherical retaining hole, and ball 9 is positioned at spherical pore also can Free-rolling. A part for ball 9 is protruded outside retainer 10, for processing work. The Free-rolling of ball 9 can ensure ball even wearing, thereby has extended ball service life, has ensured machining accuracy. Described ball can be selected sintered carbide ball or Ceramic Balls.

Now, supporting base 8, ball 9 and retainer 10, as integral type part, ensure that they can rotate simultaneously.
Described excellent power glue 6 is positioned at ball bearing seat 8 tops, and has certain interval with the inwall of cutter connecting cylinder 7. Excellent power glue is a kind of a kind of new material between plastics and rubber, has intensity good, the characteristic that compression is little. There is compression in excellent power glue 6, and slight expansion occurs in the time being subject to axial force. In the time that excellent power glue 6 is subject to cutter connecting cylinder 7 inner wall limit, the compressive strength of excellent power glue becomes larger. Therefore, excellent power glue 6 not only provides certain compression, and suitable compressive strength is provided, and has ensured that cutter head is in bearing certain roll extrusion power, can eliminate whole or in part the processing vibration bringing because of surface of the work out-of-flatness.
The bottom of described sensor holder 5 has screwed hole, and sensor holder 5 is positioned at the top of excellent power glue 6. Excellent power glue 6, retainer 10 have central through hole, and ball bearing seat 8 has shoulder hole. By soket head cap screw, integral type part (supporting base 8, ball 9 and retainer 10), excellent power glue 6 are connected to ball bearing seat 8. The object of design is like this: supporting base 8, ball 9 and retainer 10 belong to part easy to wear, and after their wearing and tearing, we only need dismounting soket head cap screw, the integral type part (supporting base 8, ball 9 and retainer 10) more renewing. Therefore, save the replacing time, improved working (machining) efficiency.
The top of described sensor holder 5 has hole and groove, power sensor 4 is positioned at sensor holder 5, the top of power sensor 4 is force bearing plates 3, and the top of force bearing plate is that 2, two upright soket head cap screws of handle of a knife contiguous block link together handle of a knife contiguous block 2 and force bearing plate 3; Force bearing plate 3 and sensor holder 5 are installed with contour sleeve 13 in symmetrical both sides. Contour sleeve is a kind of cannulated sleeve. The soket head cap screw standing upside down, through the centre bore of contour sleeve 13, is connected to sensor holder 5 on handle of a knife contiguous block 2. In this cutter, the effect of contour sleeve is to ensure to leave certain distance between force bearing plate 3 and sensor holder 5. Sensor 4 does not contact with force bearing plate under free state. In the time that cutter is depressed surface of the work, sensor holder 5 is with dynamic sensor 4 to move upward, until contact also stressed with force bearing plate 3. In this process, contour sleeve 13 play the guiding role. Now, power sensor 4 outputs to Displaying Meter by signal connecting line by pressure signal. By regulating the feed distance of cutter at surface of the work, can obtain the static starting force of needed rolling and processing. Before rolling and processing, need the signal connecting line of withdrawal force sensor side, while avoiding cutter to rotate, be wound around.
The lateral location of described handle of a knife contiguous block 2, force bearing plate 3, sensor holder 5, excellent power glue 6, ball bearing seat 8 and retainer 10 has keyway. Cutter connecting cylinder 7 has keyway at correspondence position. Between aforementioned part and cutter connecting cylinder 7, be installed with long key 21, be used for transmitting torque. The axial restraint of long key is fixed by the holding screw 17 being arranged on handle of a knife contiguous block 2.
Cutter, in the time carrying out roll extrusion, is sleeved on nozzle holder on cutter connecting cylinder 7 with the accurate east of cutter connecting cylinder 7, and refrigerating gas sprays near ball through cooling jet; Owing to existing four vacuum that mouth occurs near ball, make to produce strong draught head near ball, thereby make refrigerating gas form fine and close lubricating layer on ball surface, not only reduce the temperature of ball, the wearing and tearing of simultaneously lowering ball.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as the technical scheme that can realize on the basis of above-described embodiment without creative work, all should be considered as falling within the scope of the rights protection of the utility model patent.
