The purpose of this utility model is to propose a kind of heat exchanger barrel welding tool that can effectively improve argon shield effect, improve welding quality and convenient welding.
For reaching this object, the utility model by the following technical solutions:
Heat exchanger barrel welding tool, comprise the first cylindrical shell sealing, the second cylindrical shell sealing of both sides and connect the connector of the first cylindrical shell sealing and the second cylindrical shell sealing, described the first cylindrical shell sealing and described the second cylindrical shell sealing are used for the port sealing at described heat exchanger cylindrical shell two ends.
Preferably, described the first cylindrical shell sealing and described the second cylindrical shell sealing are disc-shaped structure and suitable with the two-port shape of described heat exchanger cylindrical shell respectively, have tracheae and pass into mouth on described the first cylindrical shell sealing.
Preferably, the outside of described the first cylindrical shell sealing and described the second cylindrical shell sealing is all pasted with sealing gasket, and the diameter of described sealing gasket is greater than the port diameter of described heat exchanger cylindrical shell.
Preferably, the periphery of described the first cylindrical shell sealing and described the second cylindrical shell sealing is all overlapped and is had sealing ring.
Preferably, described connector is at least one connecting rod, and the two ends of described connecting rod are connected with described the first cylindrical shell sealing and described the second cylindrical shell sealing respectively.
Preferably, described connecting rod is three.
Preferably, described the first cylindrical shell sealing, described the second cylindrical shell sealing and described connector are made by metallic iron.
The beneficial effects of the utility model are:
The heat exchanger barrel welding tool the utility model proposes comprises the first cylindrical shell sealing of both sides, the connector of the second cylindrical shell sealing and connection the first cylindrical shell sealing and the second cylindrical shell sealing, by the first cylindrical shell sealing and the second cylindrical shell sealing, the port at heat exchanger cylindrical shell two ends is sealed, thereby the welded seam area in welding forms airtight space, in this confined space, pass into argon gas, can reach good argon shield effect, and then raising welding quality, in addition, this frock can play certain supporting and location effect by heat exchanger cylindrical shell, convenient welding.

Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by detailed description of the invention.
Embodiment mono-:
The present embodiment provides a kind of heat exchanger barrel welding tool, for the welding of heat exchanger cylindrical shell, as shown in Figure 1, this heat exchanger barrel welding tool comprises the first cylindrical shell sealing 1, the second cylindrical shell sealing 2 of both sides and connects the connector of the first cylindrical shell sealing 1 and the second cylindrical shell sealing 2.Connector is three connecting rods 3, and the two ends of each connecting rod 3 connect respectively the first cylindrical shell sealing 1 and the second cylindrical shell sealing 2.
The first cylindrical shell sealing 1, the second cylindrical shell sealing 2 and connecting rod 3 are made by metallic iron.
The first cylindrical shell sealing 1 and the second cylindrical shell sealing 2 are disc-shaped structure and suitable with the two-port shape of heat exchanger cylindrical shell respectively, have tracheae and pass into mouth 11 on the first cylindrical shell sealing 1.
The using method of this heat exchanger barrel welding tool is, heat exchanger cylindrical shell to be welded is put into this welding tooling, make the first cylindrical shell sealing 1 and the second cylindrical shell sealing 2 seal respectively the port sealing at heat exchanger cylindrical shell two ends, thereby the welded seam area in welding forms airtight space, argon gas is passed into mouth 11 by tracheae and pass in confined space, then the weld seam of heat exchanger cylindrical shell welds.
The heat exchanger barrel welding tool that the present embodiment provides, owing to forming airtight space at the welded seam area of welding, therefore can reach good argon shield effect, and then improves welding quality.In addition, this frock can play certain supporting and location effect, convenient welding by heat exchanger cylindrical shell.
In order to improve seal; as shown in Figure 2; can all attach sealing gasket 4 in the outside of the first cylindrical shell sealing 1 and the second cylindrical shell sealing 2; the diameter of sealing gasket 4 is greater than the port diameter of heat exchanger cylindrical shell; heat exchanger cylindrical shell is put into after frock; by sealing gasket 4, the first cylindrical shell sealing 1, the second cylindrical shell sealing 2 are sealed with the cooperation place of heat exchanger cylindrical shell, further improved argon shield effect.
Wherein, the quantity of connecting rod is not limited to three, can set according to factors such as the sizes of heat exchanger cylindrical shell; Connector is also not limited to connecting rod, and other structures that can connect the first cylindrical shell sealing and the second cylindrical shell sealing all can; The material of the first cylindrical shell sealing, the second cylindrical shell sealing and connector is not limited to metallic iron, and the material of other convenient processing all can.
