Problems solved by technology

[0002] At present, after the drilling and groove processing of the header are completed, the header is placed on the V-shaped bracket or the roller frame during the process of installing welded pipe joints and other accessories. The header has not taken relevant deflection control measures and is in an open state. A large number of welding operations of pipe joints and accessories are carried out, and the deflection of the header body is seriously out of tolerance after welding. It can only be improved by the straightening operation of the header body after heat treatment.
Using such a manufacturing method increases the manufacturing cycle and cost of the header
[0003] Especially for large-diameter, thin-walled headers, the straightening operation of the header body by heat treatment may cause the risk of deformation of the header body due to force, and it is not suitable to straighten the header

Embodiment 1

[0054] A header deflection control device in the present invention, such as figure 1 , figure 2 As shown, it includes a shelf bar 1, which is provided with four supports 2 for supporting and fixing the header body, and a removable backing plate is respectively provided between each support 2 and the shelf bar 1 3. The thickness of the backing plate 3 is the same as the deflection value in the direction of the pipe hole of the header body. Side plates 7 are provided on the sides of the two supports 2 at both ends of the shelf 1, and the side plates 7 can make the header deflection control device turn over. The thickness of the backing plate 3 is H2, and the value range of H2 is: 1-10mm. A round hole is provided on the shelf 1 for the first bolt 4 to pass through the first nut 5 to install the support 2 . The upper end of the side plate 7 is fixedly connected with the support 2, and the lower end of the side plate 7 is connected with the lower end of the shelf bar 1 through ...

Embodiment 2

[0081] Such as Figure 15 , Figure 16 As shown, in the present embodiment, the number of connecting plates 2-5 on the upper arc platen 2-1 and the lower arc plate 2-2 is set to one, and the upper arc platen 2-1 and the lower arc plate 2 The other end of -2 is connected by a hinge, so that the upper circular arc pressing plate 2-1 can turn over around one end of the lower arc plate 2-2. The side plates 7 are arranged on the sides of the two supports 2 on the two ends of the shelf bar 1, and the both sides of each support 2 are provided with side plates 7, and the upper ends of the side plates 7 are fixedly connected with the supports 2, and the sides of the side plates 7 The lower end is pushed against the lower end of the shelf bar 1, and the side plate 7 is an arc-shaped structure. According to the installation position of the pipe joint on the header body, the control device of the present invention can be turned left and right for installation. The control device of the p...

Embodiment 3

[0084] Such as Figure 18 , Figure 19 As shown, in this embodiment, only one side of each support 2 is provided with a side plate 7, the outer side of the side plate 7 is an arc-shaped structure, the side plate 7 is a C-shaped structure, and the lower end of the C-shaped structure is fixed on the support. The lower end of the seat 2 and the shelf 1, the upper end of the C-shaped structure crosses the upper end of the header body to the other side of the support 2. The control device of the present invention can be turned over an angle of more than 180° through the above-mentioned side plate 7, such as Figure 20 shown.

[0085] Others are identical with embodiment 2.

Abstract

The invention discloses a header deflection control device and method. The header deflection control device comprises a shelving strip, a plurality of supporting seats used for supporting and fixing aheader body are arranged on the shelving strip, a removable base plate is correspondingly arranged between each supporting seat and the shelving strip, and side plates are arranged on the side surfaces of at least two supporting seats. The side plates are installed at two edges of the supporting seats, so that a product header achieves a function of turning over leftwards / rightwards in the process of manufacturing, welding dead angles of a header pipe joints and accessories can be obviously reduced, and the product quality is ensured. According to the header deflection control device and method, the shelving strip and the supporting seats are used for binding and manufacturing the product header, and the purpose of controlling the welding transformation (deflection) of the header is achieved.

Description

technical field [0001] The invention relates to a header deflection control device and a control method, belonging to the technical field of header assembly. Background technique [0002] At present, after the drilling and groove processing of the header are completed, the header is placed on the V-shaped bracket or the roller frame during the process of installing welded pipe joints and other accessories. The header has not taken relevant deflection control measures and is in an open state. A large number of welding operations of pipe joints and accessories are carried out, and the deflection of the header body is seriously out of tolerance after welding. It can only be improved by straightening the header body after heat treatment. Adopting such a manufacturing method increases the manufacturing cycle and cost of the header.
