Abstract
The invention relates to and provides an argon shield device for local welding, which comprises a metal box body; a short pipe connected with an inner cavity of the metal box body is arranged on the metal box body; any one side wall of the metal box body is a ventilation wall with air vents; and a seal strip protruding from the outer wall surface of the ventilation wall and surrounding the area of the air vents is arranged outside the ventilation wall. The metal box body is adopted to be jointed with the back side of a welded part of a large workpiece, argon is directly conveyed at the welded part of the large workpiece and a component by the ventilation wall on the metal box body to achieve the local argon shield; and the argon shield device has a simple and compact structure, is convenient to use and manufacture, does not need argon filling shield to the whole workpiece, effectively improves the welding efficiency and the welding quality, saves the argon amount, lowers the production cost, and is suitable for argon shield to the roots of weld joints, subjected to local welding, of the large workpiece and a workpiece that cannot be sealed.
Description
Technical field
The present invention 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; the invention provides a kind of simple in structurely, make, easy to use, reduce 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 used in the present invention 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 present invention 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 structural representation of the present invention;
Fig. 2 is that the present invention 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 invention will be further described 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.
Claims (1)
1. local welding argon protective device; it is characterized in that: comprise a metal case; metal case is provided with the short tube of a connection metal box body inner chamber; arbitrary sidewall of metal case is the gas permeable wall with air-vent, and gas permeable wall is provided with the sealing strip that protrudes its outside wall surface, surrounds the air-vent zone outward.
