Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe welding technology, and in particular to a stainless steel welded pipe cooling device. Background Technology

[0002] Stainless steel pipes are important components in modern industry. During their use, stainless steel pipes are often welded, and the weld area needs to be cooled after welding. Traditional cooling methods typically use water spray or fans. Cooling after welding is a crucial step in ensuring the quality and performance of the weld.

[0003] The commonly used water cooling method involves installing a water-spraying bamboo-joint pipe at the tail of the welding machine. As the welded stainless steel pipe passes under the bamboo-joint pipe, the water sprayed from the pipe cools it. However, this cooling method has the following drawbacks: because the stainless steel pipe is constantly moving, the contact time between the water sprayed from the bamboo-joint pipe and the stainless steel pipe is short, resulting in poor cooling effect; secondly, the bamboo-joint pipe is generally directly connected to a tap water pipe, using room temperature water to cool the stainless steel pipe, which has low cooling efficiency. Therefore, further improvements are needed. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, a stainless steel welded pipe cooling device is disclosed, comprising a base plate 1 and a spray assembly 3. The spray assembly 3 includes an outer pipe 31, and an inner pipe 32 is provided inside the outer pipe 31. Both ends of the inner pipe 32 and the outer pipe 31 are fixedly connected to an annular end plate 33, and a water storage chamber is formed between the inner pipe 32 and the outer pipe 31. A support assembly 4 is installed on the lower surface of the outer pipe 31. A cooling box 2 and a pump body 5 are fixed on the upper surface of the base plate 1. A water inlet and a first drain pipe 52 are fixed to the inlet and outlet of the pump body 5, respectively. The other end of the first drain pipe 52 is connected to the cooling box 2. A second drain pipe 21 is fixed to the top of the other side of the cooling box 2. A flexible hose 35 is fixed to the other end of the second drain pipe 21. The other end of the flexible hose 35 is fixedly connected to the side wall of the outer pipe 31 and connected to the water storage chamber. A cooling assembly 6 is installed on the top wall of the cooling box 2.

[0022] Several nozzles 34 are fixedly installed at equal intervals on the inner wall of the inner tube 32.

[0023] In this embodiment, the water pumping pipe 51 is connected to an external water tank, and several nozzles 34 are distributed along the length and radial direction of the inner pipe 32. After the pump body 5 is started, water is pumped into the cooling tank 2, and then the water is discharged from the second drain pipe 21. Then it enters the water storage chamber along the hose 35 and is finally sprayed out from several nozzles 34. When the stainless steel welded pipe passes through the inner pipe 32, the sprayed water is used to spray and cool the stainless steel welded pipe.

[0024] The cooling assembly 6 includes a metal plate 61 fixed to the upper surface of the cooling box 2. A semiconductor cooling chip 62 is fixed to the upper surface of the metal plate 61. The cooling side of the semiconductor cooling chip 62 is attached to the metal plate 61. Several cooling chips 63 are fixed below the metal plate 61. The several cooling chips 63 extend through the top wall of the cooling box 2 into the interior of the cooling box 2.

[0025] When the semiconductor cooling chip 62 is activated, the cooling side of the semiconductor cooling chip 62 cools the metal plate 61, and the cooling plate 63 is cooled by the metal plate 61, thereby using the cooling plate 63 to cool the water passing through the cooling box 2.

[0026] A number of heat sinks 64 are fixed on the top heat dissipation side of the semiconductor cooling chip 62, and a fan 65 is fixed on the top of the heat sinks 64.

[0027] By setting up heat sink 64 and fan 65, the heat dissipation effect of the heat dissipation side of the thermoelectric cooler 62 is ensured, thereby ensuring that the thermoelectric cooler 62 can operate normally.

[0028] The support assembly 4 includes a mounting plate 41, a vertical tube 42 is fixed in the middle of the upper surface of the mounting plate 41, and the top of the vertical tube 42 is open. A support rod 43 is slidably connected inside the vertical tube 42, and the top of the support rod 43 is fixedly connected to the lower surface of the outer tube 31. Multiple mounting holes are provided on the mounting plate 41.

[0029] In this embodiment, the mounting plate 41 is fixedly installed at the tail of the welding machine by screws inserted through the mounting holes, and the stainless steel pipe coming out of the welding machine passes right through the inside of the inner tube 32. The support rod 43 can slide up and down along the vertical tube 42 to adjust the height of the outer tube 31, ensuring that the stainless steel pipe can just pass through the inside of the inner tube 32.

[0030] A locking bolt 44 is threaded through the top side wall of the vertical tube 42 and rotated through it. One end of the locking bolt 44 inside the vertical tube 42 is in contact with the surface of the support rod 43.

[0031] After adjusting the height of the spray assembly 3 by moving the support rod 43, tighten the locking bolt 44 to press and fix the support rod 43.

[0032] Working principle: First, fix the mounting plate 41 of the support assembly 4 to the tail of the welding machine, and move the support rod 43 up or down to adjust the height of the spray assembly 3 so that the stainless steel pipe coming out of the welding machine can pass through the inside of the inner pipe 32. Then tighten the locking bolt 44 to fix the support rod 43. When cooling the stainless steel pipe, start the pump body 5 and the semiconductor cooling chip 62. The pump body 5 draws water from the external water tank and pumps it into the cooling tank 2. The cooling chip 63 is used to cool the water. The cooled water is discharged from the second drain pipe 21 and enters the water storage chamber between the inner pipe 32 and the outer pipe 31 through the hose 35. Finally, the cold water is sprayed out from the nozzle 34, and the sprayed cooling water is used to spray and cool the stainless steel pipe.
