Description

Welding table capable of preventing steam from dissipating

Technical Field

The utility model relates to a manufacturing field of welding steel pipe, in particular to prevent welding bench of steam loss.

Background

The welded steel pipe is formed by bending a steel strip or a steel plate into a circular pipe shape and then welding the surface seams. Welded steel pipes have been replacing seamless steel pipes in more and more fields, at a lower cost and with higher production efficiency than seamless steel pipes. In the production process of the welded steel pipe, the steel pipe needs to be sprayed with water for cooling immediately after welding due to process requirements.

As shown in fig. 1, during the production process of the welded steel pipe 1, the welded steel pipe 1 needs to be welded with a seam 11 after being bent. The position of the welded steel pipe 1 is limited by the limiting mechanism 23 when the welded steel pipe 1 is welded by the existing welding table body 2, so that the accuracy of the welding position is ensured. The welded steel pipe 1 is continuously produced and continuously conveyed through the limiting mechanism 23, and the welding gun 21 welds the seam 11 of the welded steel pipe 1. The water spray pipe 22 sprays cooling water to the welded steel pipe 1 after welding to cool the welded steel pipe 1. After cooling the welded steel pipe 1, the cooling water falls onto the work table 24, flows from the upper surface of the work table 24 into the drain grooves 3 provided in the side surfaces of the work table 24, and flows into the drain along the drain grooves 3.

When the water spray pipe 22 on the welding table body 2 sprays cooling water on the welded steel pipe 1 after welding, a large amount of water vapor is generated when the high-temperature welding pipe contacts the cooling water. The continuously generated water vapor can improve the air humidity in the workshop and is not beneficial to the rust prevention of other metal equipment in the workshop, so the improvement is needed.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in figure 2, the welding table for preventing steam from escaping comprises a welding table body 2, a water drainage tank 3 and an air exhaust mechanism 4.

As shown in fig. 1, during the production of the welded steel pipe 1, the welded steel pipe 1 needs to be welded with a seam 11 on the upper surface after being bent.

The welding table body 2 includes a welding torch 21, a water spray pipe 22, and a stopper mechanism 23. When the welding gun 21 welds the weld seam 11, the pipe body of the welded steel pipe 1 is restrained by the stopper mechanism 23. The limiting mechanism 23 includes a limiting wheel 231 and a limiting block 232. The welded steel pipe 1 moves axially along the length direction thereof in the direction from the welding gun 211 to the spray pipe 212, and the pipe body of the welded steel pipe 1 passes through the groove between the limiting wheel 231 and the limiting block 232 to ensure the accuracy of the welding position.

Due to the process requirements, the welded steel pipe 1 needs to be cooled immediately, and the water spray pipe 22 sprays water to cool the joint 11 on the welded steel pipe 1. Most of the cooling water falls onto the work table 24 after the seam 11 is completely cooled, flows into the drain groove 3 provided in the side surface of the work table 24 and having an open end from the upper surface of the work table 24, and flows into the drain along the drain groove 3. And a small amount of cooling water is vaporized into water vapor to be dispersed in the air due to the contact with the high-temperature welded steel pipe 1.

As shown in fig. 2, the air extracting mechanism 4 includes an air suction cover 41 disposed above the welded steel pipe 1, an air suction pipe 42 fixedly connected to the air suction cover, a water storage tank 43 disposed below the air suction pipe 42, a U-shaped pipe 44 disposed below the water storage tank 43, and a drain pipe 45.

The suction hood 41 has a circular truncated cone shape, and may have a square truncated cone shape in other embodiments, and is provided directly above the position where the cooling water contacts the welded steel pipe 1. The end of the suction cover 41 with a smaller diameter is fixedly connected with the suction pipe 42, and the fixing mode can be determined according to the actual situation, and is welded here. The larger end of the caliber of the air suction cover 41 faces the position where the cooling water is contacted with the welded steel pipe 1, so that the water vapor can be collected conveniently.

The number of the air suction pipes 42 is one, one end of each air suction pipe is fixedly connected and communicated with the air suction cover 41, and the other end of each air suction pipe is communicated with the air suction equipment. The suction pipe 42 is provided with a V-shaped portion 421 so that the cooling water condensed in the tube body of the suction pipe 42 naturally flows down along the tube wall.

The water storage tanks 43 are one in number, and the upper ends thereof communicate with the bottom of the V-shaped portion 421. The water storage tank 43 is cubic, but may be cylindrical or spherical in other embodiments. The water storage tank 43 is hollow and located right below the bottom of the V-shaped portion 421, and is used for receiving and storing the condensed water flowing to the bottom of the V-shaped portion 421.

The number of the U-shaped tubes 44 is one, and the tube diameter thereof is smaller than that of the suction tube 42. One end of the U-shaped pipe 44 is communicated with the bottom of the water storage tank 43, and the other end is communicated with the drain pipe 45. The water stored inside the U-shaped pipe 44 prevents the external air from entering the suction pipe 42 through the discharge pipe 45.

The volume of the tank body of the water storage tank 43 is larger than that of the pipe body of the U-shaped pipe 44, that is, after the negative pressure in the air suction pipe 42 is too large and the water in the U-shaped pipe 44 is accidentally pumped into the water storage tank 43, the water storage tank 43 can contain all the water in the U-shaped pipe 44, and the water is prevented from being directly pumped to the bottom of the V-shaped part 421 to block the air suction pipe 42.

The drain pipes 45 are one in number and are provided obliquely downward toward the drain tank 3. The pipe body caliber of the drain pipe 45 is the same as the pipe body caliber of the U-shaped pipe 44. The top end of the drain pipe 45 is communicated with the U-shaped pipe 44, and the bottom end of the drain pipe 45 is positioned above the drain tank 3. The water discharged from the U-shaped pipe 44 flows into the drain tank 3 along the drain pipe 45 and is drained away.

The number of the support columns 5 is two, and the support columns are vertically arranged on the upper surface of the workbench 24. For supporting the suction duct 42.

The utility model discloses a theory of operation:

the welded steel pipe 1 is contacted with cooling water sprayed from the spray pipe 22 to generate a large amount of water vapor, and the suction cover 41 expands the suction range of the suction pipe 42 to draw away the large amount of water vapor generated in the cooling process. Meanwhile, the suction hood 41 and the suction pipe 42 cool the water vapor into condensed water, and the suction hood 41 may direct a portion of the condensed water to directly fall on the work table 24 and be discharged from the drain tank 3. The condensed water cooled in the air suction pipe 42 flows into the water storage tank 43, and the water storage tank 43 is matched with the U-shaped pipe 44, so that the continuous drainage function is realized, and the liquid sealing effect of the U-shaped pipe 44 prevents partial suction effect of the air suction pipe 42 from dispersing to the tail end of the drainage port 45 due to the fact that the drainage pipe 45 is communicated with the outside. Thereby improving the air suction efficiency of the air suction pipe 42, reducing the possibility of water vapor escape and further reducing the possibility of rusting of other metal equipment in a workshop.
