U-shaped sectional material arc-bending die and using method thereof

Abstract

The invention provides a U-shaped sectional material arc-bending die and a using method thereof. The die comprises a main board, a U-shaped groove I is formed in the upper part of the main board, themain board comprises a guide type main board and a fixed type main board, wherein guide plates are arranged on the two sides of a bolt hole at the bottom of the guide type main board, hollow U-shapedgrooves II are formed in the middle parts of the guide plates, fixing plate bodies are arranged on the two sides of the bottom of the fixed main board, and bolt holes are formed above the two ends ofthe main board; and an upper pressing plate matched with the U-shaped groove I is arranged above the main plate, and bolt holes matched with the upper parts, on the two ends of the main board, of themain board are formed in the two ends, on the cross beam, of the upper pressing plate; the using method comprises the following steps that the specific size of the die is designed according to the contour of the U-shaped sectional material;, a plurality of ejection bending stress points are arranged according to the length and the bending radius of the U-shaped sectional material, and the ejectingbending data of each point position are determined; a sample is placed on a steel platform, and a die is assembled; a backer is assembled; the U-shaped sectional material is placed in the U-shaped grooves of the die; hydraulic equipment is installed; heating is performed in a flame point mode; and unloading is performed, an upper pressing plate is dismounted, and the U-shaped sectional material is taken out. The U-shaped sectional material arc-bending die and the using method thereof can effectively improve the working efficiency and the quality.

Description

technical field [0001] The invention relates to the field of construction, in particular to a U-shaped profile bending mold and a method for using the same. Background technique [0002] Today's steel structure industry pays more and more attention to the uniqueness and artistry of the appearance while paying attention to the use function, especially the venues and landmark buildings, which are more modern and artistic in terms of shape. Steel structure products are designed with different cross-sections according to the different functions of different positions of building products. The cross-sections of conventional steel structure products are mostly H-shaped, box-shaped and circular, and there are also products with cross-shaped and king-shaped cross-sections. [0003] In order to achieve the specific shape required by the design, it is often necessary not only to add parts such as corbels to the existing main components, but also to bend or even bend and twist the comp...

Problems solved by technology

The lateral arc of the U-shaped profile, because the force-bearing part is just located on the weak axis, in the process of cold bending and hot bending, the transmission of force cannot be controlled, so it is impossible to process the U-shaped profile with a lateral arc.

After consulting a number of professional profile bending units, the result is that none of them have the lateral bending ability of this kind of U-shaped profile
