Problems solved by technology
In the prior art, in the production process of the side beam of the truck chassis, the pre-deflection modulation of the I-shaped center beam is usually adjusted by heating the pre-deflection or a simple pre-deflection modulation tooling, and the pre-deflection curve is generally multi-point. Bending straight lines, and the use of simple pre-deflection modulation tooling cannot ensure that the pre-deflection curve is uniform

Embodiment
[0021] The I-shaped center beam pre-deflection modulation device in this example is mainly used for pre-deflection modulation of the I-shaped center beam. The section shape of the I-shaped middle beam in this example is as follows image 3 It is an I-shaped beam with a higher height in the middle section and lower heights on both sides. It belongs to an I-shaped beam with a plane on one side and an inclined transition connection on the other side. According to the characteristics of the modulation object, the I-shaped center beam pre-deflection modulation device in this example is mainly composed of the modulation platform 1 at the bottom, the modulation scale 3 fixed on the top surface of the modulation platform 1, the force component 4, the center disk positioning support 5, the middle part The positioning support assembly 6, the anti-twist deformation assembly 7, the end positioning support 8 and the fixing assembly 9 are composed. The center plate positioning support 5, t...

The invention discloses an I-shaped centre sill pre-deflection modulation device which comprises a modulation platform (1). One end of the central axis (2) of the modulation platform (1) is provided with a modulation scaleplate (3), the two sides of the modulation scaleplate (3) are symmetrically provided with anti-twisting deformation assemblies (7), middle positioning supporting assemblies (6),core disc positioning supports (5) and end positioning supports (8) from inside to outside, and the two sides of the other end of the central axis (2) are symmetrically provided with force applying assemblies (4) and fixing assemblies (9) from inside to outside. According to an existing roasting method, a modulated pre-deflection curve is generally formed by multi-point type bending straight lines. The pre-deflection curve modulated by the device is a smooth and even curve or curve face, and the modulation accuracy is high. A method of the device is simple and easy to operate.
Description
technical field [0001] The invention relates to a pre-deflection modulation device of an I-shaped center beam, 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 I-shaped middle beam to ensure that the truck chassis does not sag. In the prior art, in the production process of the side beam of the truck chassis, the pre-deflection modulation of the I-shaped center beam is usually adjusted by heating the pre-deflection or a simple pre-deflection modulation tooling, and the pre-deflection curve is generally multi-point. Bending 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 pre-deflection modulating device of the I-shaped center beam to ens...
