The invention discloses a box iron side beam pre-deflection modulating device comprising a modulating platform (1). A modulating ruler (3) is arranged at one end of the central axis (2) of the modulating platform (1), middle torsion deforming preventing assemblies (7), middle positioning supporting assemblies (6), end torsion deforming preventing assemblies (5) and end clamping assemblies (8) aresymmetrically arranged on the two sides of the modulating ruler (3) from inside to outside, and profiling supports (20) are arranged between the middle torsion deforming preventing assemblies (7) andthe middle positioning supporting assemblies (6), between the middle positioning supporting assemblies (6) and the end torsion deforming preventing assemblies (5) and the outer sides of the end torsion deforming preventing assemblies (5) correspondingly. Force applying assemblies (4) and fixing assemblies (9) are symmetrically arranged on the two sides of the other end of the central axis (2) frominside to outside. A pre-deflection curve modulated by an existing fire baking method is generally composed of multi-point-type bent straight lines. A pre-deflection curve modulated by the box iron side beam pre-deflection modulating device is a smooth and even curve or hook face, and the modulating accuracy is high. The method of the box iron side beam pre-deflection modulating device is simpleand easy to operate.
Description
technical field [0001] The invention relates to a channel steel side beam predeflection modulating device, which belongs to the technical field of train chassis manufacturing. Background technique [0002] Before the assembly and welding of the middle beam of the truck chassis, it is necessary to adjust the pre-deflection of the channel steel side beams to ensure that the truck chassis does not sag. Existing technology In the production process of the side beam of the truck chassis, the pre-deflection modulation of the channel steel side beam is usually modulated by baking fire or simple pre-deflection modulation tooling, and the pre-deflection curve of the modulation pre-deflection is generally a multi-point folding It is composed of curved straight lines, and the use of simple pre-deflection modulation tooling cannot ensure that the pre-deflection curve is uniform. Contents of the invention [0003] The object of the present invention is to provide a channel steel side ...
