Multiple-segment girder

Abstract

The invention discloses a multi-segment beam. The left section of the column, the connecting left section, the middle left section, the middle right section, the connecting right section and the right section of the column are sequentially positioned and connected to form a symmetrical structure, and the left column and the right column are respectively fixed on the left section of the column and the right section of the column. Below and tangent to its outer surface, the outer surfaces of the left section and the right section of the column are arc surfaces and planes tangent to the arc surfaces, and the outer surfaces of the middle left section and the middle right section that are close to each other are arc surfaces on the same circumference. The plane on the left section of the column and the right section of the column is located on the tangent plane of the arc surface of the middle left section and the middle right section, the height of the outer surface of the left section and the right section is lower than the plane on the left section of the column and the right section of the column, the left section of the column, the column There are steel wire grooves on the outer surface of the circumference of the right section, the middle left section and the middle right section. The cross section of the left section and the right section of the column is a rectangular structure. Font-shaped structure, the invention has high shear and bending strength, is convenient for processing, transportation and assembly, and is not easy to deform and break after long-term use.

Description

technical field [0001] The invention relates to a frame for a steel wire winding hydraulic machine, in particular to a multi-section beam. Background technique [0002] The frame of the traditional steel wire winding hydraulic press adopts a semicircular beam, that is, the left and right columns are connected by multiple ridges to form a semicircular beam. The height of the semicircular beam is half of the total width of the entire frame. The overall cross-sectional shape is basically the same, which leads to its overall height and weight, average shear and bending resistance of each part, relatively low strength and rigidity, difficult processing, transportation and assembly, and high production costs. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a multi-section beam whose section is designed according to the bending moment and shear force it bears. Assembled for a long life. [0004] The technical sch...
