Abstract
A track structure for a slideway includes a track body which has a main wall and two lateral walls integrally formed at two sides of the main wall. The track body is formed by folding two sides of a metal plate with a thickness t0 and subjected to shaping process, including hot rolling, cold rolling, hot drawing, cold drawing, or hot and cold forging, to make the main wall has a shrinkage c1, the two lateral walls have a shrinkage c2, c1 and c2 are between ⅕ and ⅛, the main wall has a thickness t1, the lateral walls have a thickness t2, and t1=(1−c1)t0, t2=(1−c2)t0, the track body has a shaping section with a length L at each of the folded portions of the track body, and t0<L<(t12+t22)1/2.

A track structure for a slideway comprising:
- a track body with a main wall and two lateral walls integrally formed at two sides of the main wall, the track body being formed by folding two sides of a metal plate with a thickness t0, the track body being subjected to shaping process, including hot rolling, cold rolling, hot drawing, cold drawing, or hot and cold forging, to make the main wall has a shrinkage c1, the two lateral walls have a shrinkage c2, c1 and c2 are between ⅕ and ⅛, the main wall has a thickness t1, the lateral walls have a thickness t2, and t1=(1−c1)t0, t2=(1−c2)t0, the track body has a shaping section with a length L at each of the folded portions of the track body, and t0<L<(t12+t22)1/2.
A method for making a track of a slideway comprising the following steps:
- preparing a metal plate with a thickness t0, or processing a metal ingot into a metal ingot into a metal plate with the thickness t0;
- forming a track body, which has a main wall and two lateral walls integrally formed at two sides of the main wall, by folding two sides of the metal plate;
- and
- subjecting the track body to hot rolling, cold rolling, hot drawing, cold drawing, or cold and hot forging, so as to make the main wall has a shrinkage c1, the two lateral walls have a shrinkage c2, and c1 and c2 are between ⅕ and ⅛, the main wall has a thickness t1, the lateral walls have a thickness t2, and t1=(1−c1)t0, t2=(1−c2)t0, the track body has a shaping section with a length L at each of the folded portions of the track body, and t0<L<(t12+t22)1/2.
A track structure for a slideway comprising:
- a track body with a main wall and two lateral walls integrally formed at two sides of the main wall, the track body being formed by folding two sides of a metal plate and then shaping the metal plate which has been folded, the metal plate having a non-uniform thickness, a thickness ratio of the thinnest portion to the thickest portion of the metal plate being smaller than ½, and a thickness of the thinnest portion is t0, the track body being subjected to shaping process, including hot rolling, cold rolling, hot drawing, cold drawing, or hot and cold forging, to make the main wall has a shrinkage c1, the two lateral walls have a shrinkage c2, c1 and c2 are between ⅕ and ⅛, the main wall has a thickness t1, the lateral walls have a thickness t2, and t1=(1−c1)t0, t2=(1−c2)t0, the track body has a shaping section with a length L at each of the folded portions of the track body, and t0<L<(t12+t22)1/2.
