Abstract

The utility model provides a laminar flow protector for a welding gun. The laminar flow protector is sleeved at the head of the welding gun and comprises a protection cover, an annular pipe and an air inlet pipe, wherein the annular pipe is mounted in the protection cover, a hole is formed in the side wall of the protection cover, the air inlet pipe is communicated with the annular pipe after penetrating through the hole, and air holes are circumferentially and uniformly formed in the top of the annular pipe along the axis. According to the laminar flow protector for the welding gun, argon enters the annular pipe after passing through the air inlet pipe, is released from the air holes in the top of the annular pipe and flows downwards after impacting the top of the protection cover, so that the turbulent flow of the argon is prevented, a horn-shaped laminar flow circle is formed, and the head of the welding gun is coated in the flow circle and is isolated from air; and the argon becomes more uniform after flowing through multiple layers of copper wire gauzes, so that welding lines can be protected in a uniform and large-area manner, an optimal silvery white protection effect of the welding lines is achieved, and the appearance quality of products is improved.

Description

Welding gun laminar flow protective device

Technical field

The utility model relates to a kind of welder, particularly a kind of welding gun laminar flow protective device.

Background technology

In the container manufacturing process of titanium and titanium composite plate, in the welding of titanium material, prevent that the weld seam oxidation from being an emphasis, also be a difficult point.1, to use highly purified argon gas; 2, want strict control technological parameter; 3, to use rational safeguard measure, more than some be difficult to aborning remain, cause some position peroxidating, the weld seam color is turned blue.

The utility model content

(1) technical problem that will solve

The technical problems to be solved in the utility model provides a kind of laminar flow that can form and protects weld seam, prevents the weld seam peroxidating, improves the welding gun laminar flow protective device of weldquality.

(2) technical scheme

For solving the problems of the technologies described above; the utility model provides a kind of welding gun laminar flow protective device; be set in the head of welding gun 3; comprise protective cover 1, ring pipe 2 and air inlet pipe 5; described ring pipe 2 is installed in the described protective cover 1; the sidewall of described protective cover 1 is offered porose, and described air inlet pipe 5 is communicated with described ring pipe 2 after passing described hole, and the top of described ring pipe 2 circumferentially is evenly equipped with pore along axis.

Further, also draw together copper mesh 4 and collar 6, described copper mesh 4 is installed in the described protective cover 1 and is positioned at described ring pipe 2 bottoms, and described collar 6 is fixedly mounted on described copper mesh 4 bottoms.

Further, described copper mesh 4 is at least three layers.

Further, described collar 6 is made by steel wire.

Further, described ring pipe 2 is made of copper.

(3) beneficial effect

The utility model welding gun laminar flow protective device, argon gas enters ring pipe after by air inlet pipe, discharge from the pore at ring pipe top, behind the argon gas impact protector cover top to dirty, prevent that argon gas from forming turbulent flow, thereby form a tubaeform laminar flow circle, the welding gun head is coated in this laminar flow circle, make its secluding air; Argon gas becomes more even after by some layers of copper mesh, therefore can even and large-area protection weld seam, and make weld seam reach argenteous best protection effect, improved the presentation quality of product.

Fig. 2 is the structural representation of the ring pipe of the utility model welding gun laminar flow protective device.

The specific embodiment

Consult Fig. 1～Fig. 2, the utility model provides a kind of welding gun laminar flow protective device, be set in the head of welding gun 3, be used for air-isolation, comprise protective cover 1, ring pipe 2 and air inlet pipe 5, ring pipe 2 is joined end to end by hollow circular-tube and turns to annular, ring pipe 2 is installed in the protective cover 1, and the sidewall of protective cover 1 is offered porose, and air inlet pipe 5 is communicated with ring pipe 2 after passing this hole, the top of ring pipe 2 circumferentially is evenly equipped with pore along axis, and the diameter of this pore is more than or equal to 1mm and smaller or equal to 5mm; In order to be that air-flow is more even, the utility model is also drawn together copper mesh 4 and collar 6, and copper mesh 4 is installed in the protective cover 1 and is positioned at ring pipe 2 bottoms, and collar 6 is fixedly mounted on copper mesh 4 bottoms, is used for the fixed copper silk screen, prevents the downward landing of copper mesh; In order further to improve the air-flow uniformity, this copper mesh 4 is at least three layers, preferably six layers; In the present embodiment, collar 6 is made by steel wire; Ring pipe 2 is made of copper, and it can improve radiating rate, prevents overheating deforming.

The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
