Manufacturing method of extra-thick plate bending-torsion part

Abstract

The invention discloses a manufacturing method of an extra-thick plate bending-torsion part. The method comprises the steps of designing a part template with bend allowance according to the developedview of a target bending-torsion part, and in the direction perpendicular to a bending line marked on the part template, the overall dimension of the bend allowance is equal to the opening size of a lower mould; then, bending the part template into a preset shape through bending equipment, and cutting off the process allowance of the bent part template so that the bending-torsion part of which theshape is the same as the shape of the target bending-torsion part can be obtained. The manufacturing method of the extra-thick plate bending-torsion part is high in operability and low in cost.

Description

technical field [0001] The invention relates to the field of workpiece manufacturing, in particular to a method for manufacturing extra-thick plate bending and torsion parts. Background technique [0002] In the design of steel structures, bending and torsion parts have a wide application space as a special-shaped part. The plates need to be flexed and twisted synchronously to ensure that the column body and corbel are aligned. Since the plate thickness of the parts in the node area is often large, and in order to ensure the manufacturing accuracy of the components, the size of the parts for bending and torsion will not be too large. [0003] In the prior art, the manufacturing method of bending and torsion parts of extra-thick plates (thickness greater than 60 mm) is generally to reserve a margin of material according to the empirical method, and then directly stamp the material on the bending machine, but the reserved Too much margin will cause a lot of waste of workpiec...

Problems solved by technology

[0004] The main purpose of the present invention is to provide a method for making extra-thick plate bending and torsion parts, which can solve the problems in the prior art that the reserve margin based on experience will lead to high cost or the shape and precision of the bending and torsion parts do not meet the requirements
