Embodiment 1

[0030] Such as Figure 1 ~ Figure 2 As shown, the cylindrical body of the present invention has no pre-bending round forming process, comprising the following steps:

[0031] (1) Cutting and blanking: cutting and blanking of the plate according to the size required by the process;

[0032] (2) Rolling: Use a plate rolling machine to roll the cut plate in step (1);

[0033] (3) Welding: Weld the 4 side seams of the cylindrical shell formed in the step (2);

[0034] (4) Circle correction: use plate rolling machine to carry out circle correction to the cylindrical body (4) after step (3) processing;

Embodiment 2

[0036] Such as Figure 1 ~ Figure 2 As shown, step (1) and step (2) also includes step (a), processing the bevel, and processing the bevel of the plate cut in step (1). All the other are the same as embodiment one.

Embodiment 3

[0038] Such as Figure 1 ~ Figure 2 As shown, after step (4), step (b) of non-destructive testing is also included.

Abstract

The invention relates to a round forming process without pre-bending for a cylindrical body, which belongs to the field of round forming for boilers, pressure vessels, pipelines, air ducts and other cylindrical bodies. Including the following steps: (1) cutting and blanking: cutting and blanking the plate according to the size required by the process; (2) rolling: using a plate rolling machine to roll the plate cut in step (1); (3) welding: the step (2) Weld the side seam of the cylindrical body formed by the middle rolling; (4) Rolling correction: use a plate rolling machine to perform rolling correction on the processed barrel in step (3). The process of the invention is simple, the common plate rolling machine can meet the process requirements, and the cost of the enterprise is reduced.

Description

technical field [0001] The invention relates to a round forming process without pre-bending for a cylindrical body, which belongs to the field of round forming for boilers, pressure vessels, pipelines, air ducts and other cylindrical bodies. Background technique [0002] The cylinder processing pre-bending forming process is mainly used in the roll forming of cylinders such as boilers, pressure vessels, pipes, and air ducts. [0003] There are two existing cylinder rolling processes, the first one is to use a common three-roll plate rolling machine, a press and a special forming die, such as image 3 As shown, the head of the plate is pressed into the required circular arc on the press, and the pre-bent plate is rolled into a circular cylinder on the plate rolling machine, and then straight seam welding, calibration, non-destructive testing, and heat treatment (as required); Although the pressing force of the general press can meet the requirements, the clear space between t...
