Description
Technical field
The invention belongs to the milling train of workpiece attenuation, particularly relate to the in situ circulating milling train that rolls motionless or that rotate in situ of workpiece.
Background technology
The technology of present ironed workpiece has two kinds: the one, and workpiece is motionless in situ, and workpiece is ironed by the rectilinear motion milling train of high pressure, and this shortcoming is the easy crushed damage of workpiece, and requires the pressure of milling train very large, and milling train is very expensive, and investment requires large.The 2nd, milling train is motionless, and workpiece is pulled into rectilinear motion, and it is limited that this shortcoming is that workpiece once grinds thin amount, and occupied ground is large, and milling train is very expensive, and investment requires large.
Summary of the invention
The purpose of this invention is to provide the milling train that simple in structure, low price, occupied ground are little, use the thin workpiece of stone roller of safety.
Structure of the present invention is:
The circulating milling trains that roll that form of two groups of rotating cones up and down, comprise main stand 1, lower bearing bracket 2 and upper spider 3, below main stand 1, be fixed with lower bearing bracket 2, on lower bearing bracket 2, be provided with upper spider 3, being connected of 1 one-tenth upper energy that glides of upper spider 3 and main stand, it is characterized in that:
On lower bearing bracket 2, be provided with the next rotating cone group that a plurality of rotating cones 4 form, the cone point of each rotating cone 4 concentrates on a central point in the next rotating cone group, it is the next rotating cone group switching centre point 5, the top contact workpiece alignment 9 of each rotating cone 4 is on same plane in the next rotating cone group, and this plane is the next rotating cone group plane 6; Each rotating cone 4 of the next rotating cone group is rotationally connected with lower bearing bracket 2;
Below upper spider 3, be provided with the upper rotating cone group that a plurality of rotating cones 4 form, the cone point of each rotating cone 4 concentrates on a central point in the upper rotating cone group, it is upper rotating cone group switching centre point 7, the following contact workpiece alignment 9 of each rotating cone 4 is on same plane in the upper rotating cone group, and this plane is upper rotating cone group plane 8; Each rotating cone 4 of upper rotating cone group is rotationally connected with upper spider 3;
The next rotating cone group switching centre point 5 parallels with the glide direction straight line of upper spider 3 on main stand 1 with line between the upper rotating cone group switching centre point 7;
It is corresponding and parallel that the rotating cone 4 contact workpiece alignments 9 of the next rotating cone group and the rotating cone 4 of upper rotating cone group contact workpiece alignment 9;
