Abstract
The utility model provides a local welding argon protection device which comprises a metal box body. A short pipe connected with the inner cavity of the metal box body is arranged on the metal box body, any one side wall of the metal box body is an air-permeable wall provided with air-permeable holes, and a sealing strip protruding out of the outer wall face and surrounding an air-permeable hole region is arranged outside the air-permeable wall. The metal box body adheres to the back side of the welding position of a large workpiece, and argon is directly delivered to the welding position of the large workpiece and a part through the upper air-permeable wall of the metal box body so as to achieve local argon protection. The local welding argon protection device is simple and compact in structure and convenient to manufacture and use and does not need argon filling protection of the whole workpiece, the welding efficiency and the welding quality are effectively improved, the argon using amount is saved, the production cost is reduced, and the local welding argon protection device is suitable for argon protection of locally welded weld roots of the large workpiece and a workpiece which cannot be airtight.
Description
Technical field
The utility model relates to a kind of tool for welding, is a kind of argon protective device for local welding specifically.
Background technology
At present, welding profession is when argon arc welding large-size pipe or complex-shaped or the workpiece that can't seal, what generally adopt is the argon-filling method of one-piece machine member, the method is not only lost time but also waste argon gas, particularly when can't airtight large-scale workpiece carrying out the argon arc welding welding part, required enclosure space is very large, and the argon gas consumption is large, processing time consuming, energy consumption are high, and enterprise's production cost is high.
Summary of the invention
Deficiency for one-piece machine member sealing argon-filled protection welding in the prior art; it is a kind of simple in structure that the utility model provides, and making, easy to use reduces the argon gas consumption; energy-saving and cost-reducing, the local welding argon protective device of Effective Raise working (machining) efficiency, Decrease production cost, assurance welding quality.
The technical solution adopted in the utility model is: a kind of local welding argon protective device; its technical characterstic comprises a metal case; arbitrary sidewall of metal case is the gas permeable wall with air-vent; gas permeable wall is provided with the sealing strip that exceeds its outside wall surface, comprises air-vent outward, and metal case is provided with the short tube of a connection metal box body inner chamber.
When this device is used on the large-scale workpiece welding part, the gas permeable wall of metal case is fitted in the large-scale workpiece weld back side, by short tube the metal case inner chamber is supplied argon gas, argon gas is directly delivered to the large-scale workpiece weld back side by gas permeable wall and by the root of weld welding part place on the large-scale workpiece is protected, need not protect by the whole logical argon of large-scale workpiece, when effectively saving the Welder, increase work efficiency, reduce the argon gas consumption, reduce production costs; Sealing strip on the gas permeable wall closely is pressed on the large-scale workpiece weld back side, and argon gas is carried good airproof performance, is conducive to improve argon shield performance and welding quality.
The utility model adopts a metal case to fit in the large-scale workpiece weld back side; directly carry argon gas to realize local argon shield by gas permeable wall on the metal case to large-scale workpiece and parts weld; it is simple in structure, compact; making, easy to use; need not the one-piece machine member argon-filled protection, Effective Raise welding efficiency and welding quality are saved the argon gas consumption; reduce production costs, the root of weld of be applicable to large-scale workpiece, carrying out local welding on can't airtight workpiece carries out argon shield.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model uses structural representation.
Among the figure: large-scale workpiece tube wall 1, parts 2, metal case 3, gas permeable wall 4, air-vent 5, sealing strip 6, short tube 7.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Shown in Figure 1; a kind of local welding argon protective device comprises a metal case 3; arbitrary sidewall of metal case 3 is the gas permeable wall 4 with air-vent 5; be provided with the sealing strip 6 that exceeds its outside wall surface, comprises air-vent outside the gas permeable wall 4, metal case 3 is provided with the short tube 7 of a connection metal box body 3 inner chambers.
Shown in Figure 2; when this protective device uses; welding part 2 on large-scale workpiece tube wall 1; in the perforate of weld root; the gas permeable wall 4 of this protective device is aimed at large-scale workpiece tube wall 1 back side; make air-vent 5 corresponding root perforates; outside air feed is supplied gas by 7 pairs of metal case 3 inner chambers of short tube; protective gas is sent into gap between gas permeable wall 4 and the large-scale workpiece tube wall 1 by metal case 3 by air-vent 5; sealing strip 6 seals; protective gas is delivered to large-scale workpiece tube wall 1 and parts 2 welds by the root perforate, plays the welding protection effect, and large-scale workpiece need not whole logical protective gas.
