Abstract
A mill for cross rolling, comprising a detachable housing (1) inside which there are disposed parallel plates (4) and (5) provided with wedge-shaped deforming tools (9) and (10). On upper and lower portions (2) and (3) of the housing (1) there are provided projections (13) having through coaxial openings whereinto are introduced rotary pins (14) and (15) having cylindrical and shaped portions (16) and (17). The rotary pins (14) and (15), while being in one position, rigidly connect the portions (2) and (3) of the housing (1) and, when turned by an angle of 180.degree., allow the load to be operatively removed from a seizured billet.
Claims6
A mill for cross rolling, said mill comprising:
- a detachable box-shaped housing having upper and lower portions, said upper and lower portions of said housing being releasably interconnected along contacting surfaces;
- projections and recesses provided along a line between said contacting surfaces of said upper and lower portions of said housing such that each of said upper and lower portions are provided with projections and recesses, said projections having coaxial through openings formed therein;
- rotary pins carried in said coaxial openings thereby interconnecting said upper portion to said lower portion, said rotary pins having cylindrical portions received in said openings formed in said projections of the lower part of said housing, said rotary pins having shaped portions being arranged in said openings formed in said projections of the upper portion of said housing, said shaped portions each having a cross-section that permits a contact arc between each shaped element and an inner portion of the opening of the projection to be defined by a central angle of less than 180.degree.;
- parallel plates received in the housing, at least one of said plates being mounted on guides for reciprocation;
- wedge-shaped deforming tools mounted on opposite surfaces of said plates;
- and drive means connected with at least one of said plates.
