Abstract
A kind of pipeline soldering connecting structure, is characterized in that: have multiple protrusion seamed edge at the first mother metal mouth of pipe, and the first mother metal protrudes seamed edge and is connected with the second mother metal endoporus interference, and the part of the first mother metal except protruding seamed edge leaves weld gap with the second mother metal.The protrusion seamed edge of the first mother metal mouth of pipe can be impact style processing also can be the heterotype tubing directly processed.First mother metal protrudes seamed edge and is connected with the second mother metal endoporus interference, and before making soldering, fix relative with the second mother metal of the first mother metal is not scattered.Pipeline soldering connecting structure of the present utility model, processing cost is low, applicable most pipe profile, and throat depth is unified, and weld length is large, greatly improves weld strength.
Description
Technical field
The utility model belongs to soldering and manufactures field, is related specifically to a kind of soldering of pipeline.
Background technology
Along with the fast development of China's industry, pipeline soldering application is in the industry more and more wider, but the soldering of pipeline exists a difficult problem for butted part processed complex or weld strength deficiency always.As the mode of patent 201110361784.7, blank area adopts the oblique angle of processed complex, and throat depth can not be unified.The and for example mode of patent 201220518999.5, two pipelines adopt interference to connect to plug part, and solder can only form weld seam at end face and little toroidal extension, and weld length is little, and weld strength is not enough.
Summary of the invention
Pipeline soldering connecting structure of the present utility model, processing is simple, and throat depth is unified, and weld length is large, and weld strength is large, solves the above-mentioned drawback of existing pipeline soldering.
The technical scheme that the utility model solves the problem is: a kind of pipeline soldering connecting structure, it is characterized in that: have multiple protrusion seamed edge at the first mother metal mouth of pipe, protrude seamed edge to be connected with the second mother metal endoporus interference, and the part of the first mother metal except protruding seamed edge leaves optimum weld gap with the second mother metal.
The beneficial effect of the invention: pipeline soldering connecting structure of the present utility model, processing cost is low, applicable most pipe profile, and throat depth is unified, and weld length is large, greatly improves weld strength.

1-first mother metal, 2-solder, 3-second mother metal in figure.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
The first step: as shown in Fig. 1 Fig. 2, adopts impact style to process (4) individual protrusion seamed edge the first mother metal (1) mouth of pipe, and the first mother metal (1) also can the heterotype tubing that directly processes of Shi Guan factory.
Second step: as shown in Figure 1, adopts the mode reaming of punching press to the hole size needed the second mother metal (3) mouth of pipe, if the second mother metal (3) is the hole size that joint also directly can process needs.
3rd step: as shown in Fig. 1 Fig. 2, fills the second mother metal (3) inside with solder (2), and solder (2) can be the multi-form solder such as weld-ring, weldering mud.
4th step: by forcing press or other modes, the first mother metal (1) is inserted in the second mother metal (3) endoporus as shown in Figure 2, the protrusion seamed edge of the first mother metal (1) is connected with the endoporus interference of the second mother metal 3, and before making soldering, fix relative with the second mother metal (3) of the first mother metal (1) is not scattered.
5th step: the part installed is put into soldering oven or directly heating make solder melt welding.
In the present embodiment, the protrusion seamed edge number of the first mother metal (1) punch process can be changed according to the first mother metal (1) external diameter and service condition, but generally minimum three.
In the present embodiment, the first mother metal (1) external diameter of part and difference in height of the second mother metal (3) internal diameter except protruding seamed edge is weld bead height, determine optimum weld bead height according to welding material and technique, then adjust the second mother metal (3) internal diameter size and make weld bead height reach optimum weld bead height.
In the present embodiment, the first mother metal (1) protrusion external diameter of seamed edge and the difference of the second mother metal (3) internal diameter are the magnitude of interference, processing mode according to the 4th step selects magnitude of interference size, then adjust the first mother metal (1) and rush core size, namely adjust the external diameter that the first mother metal (1) protrudes seamed edge, make the magnitude of interference reach requirement.
Claims (2)
1. a pipeline soldering connecting structure, its characteristic is: the first mother metal mouth of pipe has protrusion seamed edge, and the first mother metal protrudes seamed edge and is connected with the second mother metal endoporus interference, leaves weld gap between the first mother metal and the second mother metal.
2. a kind of pipeline soldering connecting structure according to claim 1, is characterized in that, the protrusion seamed edge of the first mother metal mouth of pipe can be impact style processing.
3. a kind of pipeline soldering connecting structure according to claim 1, is characterized in that, the first mother metal protrudes seamed edge and is connected with the second mother metal endoporus interference, and before making soldering, fix relative with the second mother metal of the first mother metal is not scattered.
