Embodiment 1

[0025] A tree structure pipe welding anti-deformation device, which consists of: 2 transition plates 6, and a cylinder 13 is installed between the 2 transition plates, wherein the lower transition plate is embedded in the seam of the upper plane of the bottom plate 11 , and welded and fixed with the base plate, the pull rod 9 passes through the cylinder and the upper and lower transition plates, the bottom of which is threadedly connected with the base plate, and the top is respectively equipped with a washer A8 and a nut A7, and the plane on the base plate is connected with 4 bolts respectively. The positioning block 5 is connected, the V-shaped groove above the positioning block is attached to the bottom of the spray pipe 14, the upper part of the spray pipe is attached to the V-shaped groove below the pressure plate 1, and passed through a set of backing plates and bolts 2 , Washer B4 and nut B3 are fixed.

Embodiment 2

[0027] According to the tree structure pipe welding anti-deformation device described in Embodiment 1, the positioning blocks are evenly and symmetrically arranged, and four legs 10 are respectively installed between the two positioning blocks, and the legs are threaded. It is connected with the bottom plate and arranged evenly and symmetrically. The middle of the bottom plate is a hollow structure. The cylinder is at an angle of 60 degrees to the spray pipe. The spray pipe has a set of holes. The holes are arranged axially in n groups.

Embodiment 3

[0029] A positioning method for welding an anti-deformation device using the tree structure pipe described in Embodiment 1-2, the method includes the following steps:

[0030] First, process the middle position of the plane on the bottom plate into a spigot with the same diameter as the transition plate, so that the bottom surface of the spigot is parallel to the lower plane of the bottom plate, and at the same time process a threaded hole at the center of the spigot so that it is perpendicular to the bottom surface of the spigot, and then The transition plate is put into the seam and fixed by welding, and the cylinder is placed in the seam between the two transition plates, and fixed by the tie rod, washer A and nut A;

[0031] Then fix the four spray pipes on the positioning block in turn, clamp them respectively through a set of backing plates, bolts, washers B, and nuts B, and fit one end of the four spray pipes to the outer circle of the cylinder, Make the axis of the cyl...

Abstract

The invention relates to a tree-shaped structure pipe welding anti-deformation device and a positioning method thereof. In a discharging device, when a tree-shaped structure pipe is welded, the deformation problem is difficult to solve, especially when four spraying pipes need to be welded on a barrel body by a 60-degree included angle and the shape, size and tolerance requirements of the spraying pipes can not be controlled if without an auxiliary device. The device comprises two transition plates (6), wherein a cylinder body (13) is arranged between the two transition plates, and the lower transition plate is embedded into a limiting groove of the plane of a bottom plate (11) and is welded and fixed with the bottom plate; a pull rod (9) penetrates through the cylinder body and the upper and lower transition plates, wherein the lower portion of the pull rod is in threaded connection with the bottom plate, and the upper portion of the pull rod is provided with a gasket A (8) and a nut A (7); the plane of the bottom plate is connected with four positioning blocks (5) through bolts, wherein V-shaped grooves above the positioning blocks are attached to the bottoms of spraying pipes (14), and the upper parts of the spraying pipes are connected with the V-shaped grooves below a pressure plate (1). The tree-shaped structure pipe welding anti-deformation device and the positioning method thereof is used for preventing deformation during the welding of a tree-shaped structure pipe.

Description

[0001] Technical field: [0002] The invention relates to a tree structure pipe welding anti-deformation device and a positioning method. [0003] Background technique: [0004] In the discharge device, it is often difficult to solve the problem of deformation when welding pipes with a tree structure. In particular, there are four spray pipes that need to be welded on the cylinder at an angle of 60 degrees. Without auxiliary devices, the shape here cannot be controlled. Dimensions and tolerance requirements. There is an urgent need for a welding anti-deformation system for pipes with a tree structure to meet the shape, size and tolerance of the product after welding. [0005] Invention content: [0006] The object of the present invention is to provide a tree structure pipe welding anti-deformation device and positioning method. [0007] Above-mentioned purpose realizes by following technical scheme: [0008] A pipe welding anti-deformation device with a tree structure, whi...
