Problems solved by technology

[0002] The guide cylinder is the only relatively moving part of the reactor internals in nuclear power equipment. It is shaped like a square tube and is made of continuous sections, cladding tubes, guide plates and special flanges. It is precision-machined and welded to form 24 channels. The assembly requirements The precision is extremely high, and the structure is special, and it is easy to deform during the welding process. At present, this kind of equipment in China relies on imports. Processing technology required for cylinder processing

Embodiment Construction

[0018] Now according to accompanying drawing, the present invention is further described, a kind of processing technology of guide cylinder, and its flow process is as follows:

[0019] 1. The processing flow of the continuous section:

[0020] a. Install the template A2 on one side of the motherboard 1 first, and install the small flange 3 from the other side, then position it with the template A, and then position it with the small flange 3 through the positioning screw 6 and the small pressure plate 4, and then remove it Template A, then insert the double-hole tube 11 and C-shaped tube 12, install the large flange 8 from the other side in sequence, and position it with the template B7, then adjust the positioning screw 10 and the small pressure plate 9 to position the large flange, and then remove the template B, Determine the gap between the double-hole pipe 11 and the planes of the two flanges 3 and 8 to be 0.10-0.15;

[0021] b. Then insert the template C13 on the side ...

Abstract

The invention provides a guide cylinder passing die welding process. The processing flows are that parts such as a dual-hole pipe, a C-shaped pipe, a core rod, a large flange, a small flange, etc., are well fixed through a motherboard and various formworks, thus continuous sections are welded and processed; after that, the continuous section, a shell and the flange are arranged on a soleplate andfixed by bolts through an end surface pressing plate, a supporting block, a middle plate, a middle block and a middle guide plate; furthermore, a lower guide cylinder is welded. By the die tighteningwelding process, the invention avoids the technical problems that all parts are easy to deform in normal welding process, achieves the technical precision which is required by the lower guide cylinder and implements the localization of the equipment.

Description

technical field [0001] The invention relates to a processing technology of a guide cylinder, in particular to a processing technology of the guide cylinder through mold welding. Background technique [0002] The guide cylinder is the only relatively moving part of the reactor internals in nuclear power equipment. It is shaped like a square tube and is made of continuous sections, cladding tubes, guide plates and special flanges. It is precision-machined and welded to form 24 channels. The assembly requirements The precision is extremely high, and the structure is special, and it is easy to deform during the welding process. At present, this kind of equipment in China relies on imports. The processing technology required for cylinder processing. Contents of the invention [0003] The invention mainly provides a process for welding a guide cylinder through a mold. [0004] To achieve the above object, the technical scheme of the present invention is as follows: [0005] 1...
