Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

A movable air-cooled tool comprises an inner wall 1 and an outer wall 7; inner wall 1 sets up and has the certain distance in outer wall 7 the inner and between 7 with the outer wall, and the upper and lower both ends of inner wall 1 and outer wall 7 are connected and are sealed through last retaining ring 2 and lower retaining ring 4 respectively and form the wind channel, processing has a plurality of exhaust vents 5 on the inner wall 1, go up and install air-supply line 3 on the retaining ring 2, and correspond processing and have the through-hole to make air-supply line 3 and wind channel inside link up. The inner wall 1, the outer wall 7, the upper retaining ring 2 and the lower retaining ring 4 form a closed air channel, so that air can be accumulated in the air channel, and after air enters the air inlet pipe 3, the air flows out of the air outlet hole to blow hot air in the center of the air inlet pipe 1, so that the hot air flows out of the upper end of the air inlet pipe 1.

For the convenience of carrying, a handle 6 is further mounted on the upper retainer ring 2.

Two handles 6 are vertically and fixedly connected to the two opposite end faces of the upper retainer ring 2.

Three air inlet pipes 3 are fixedly connected to the upper retainer ring 2, and arc angles of 120 degrees are arranged between every two air inlet pipes 3. The air inlet pipes are uniformly arranged on the air inlet pipe 2, so that the air pressure in the air duct can be uniformly distributed.

The air outlet holes 5 are round holes with the diameter of 1mm, the air outlet holes 5 are processed on the inner wall 1 in a staggered mode, and the vertical distance between the air outlet holes 5 is 30 mm. The air outlet is a small hole, so that the pressure in the air duct can be higher than the pressure at the center of 1, and the air flowing out of the air outlet can quickly blow away the high-temperature air of the workpiece accessory.

The width of the upper retainer ring 2 and the width of the lower retainer ring 4 are both 5-10 cm.

The inner wall 1, the upper retainer ring 2 and the lower retainer ring 4 are all formed by cutting 1-1.5 mm stainless steel plates.

Three air inlet pipes 3 are fixedly connected to the upper retainer ring 2, arc angles of 120 degrees are formed between every two air inlet pipes 3, and the number of the air inlet pipes is DN 20.

As shown in fig. 2, the air outlet holes 5 are round holes of 1mm, the air outlet holes 5 are processed on the inner wall 1 in a crossed manner, and the vertical distance between the air outlet holes 5 is 30 mm. Therefore, the pipe diameter of the air inlet pipe is large enough, and the caliber of the air outlet 5 is small, so that the air near the inner wall 1 can rapidly flow and circulate on the inner wall under the action of the upper retainer ring and the lower retainer ring at the upper end and the lower end of the inner wall, the flowing speed of the air at the center of the inner wall 1 is accelerated, and the temperature of a workpiece is rapidly taken away by the air.

The width of the upper retainer ring 2 and the width of the handle 6 are both 1/20 of the length or radius of the inner wall 1.

The inner wall 1, the upper retainer ring 2, the lower retainer ring 4 and the handle 6 are formed by cutting stainless steel plates with the thickness of 1-1.5 mm, the handle at the position of the upper end face 2 of the air box is made of stainless steel plates with the thickness of 5mm, 2 stainless steel plates with the width of 20-30 mm and the length of 280-300 mm are cut, and the stainless steel plates are mechanically deformed into a common handle shape.

3 equal-length hoses matched with the air inlet interfaces are required to be prepared at the air inlet interfaces at the 3 positions shown in the figure 1 and are respectively in sealing connection with the air inlet interfaces at the 3 positions, and the other ends of the hoses are in sealing connection with the air source of the adjustable pressure pump at the same air source position. When the metal ring piece needs air cooling in the ring rolling, bulging hot working and heat treatment processes, the air cooling tool is connected with an air source, and the air cooling of the workpiece can be carried out by adjusting the pressure pump air source.

The annular air cooling tool shown in the figures 1-3 is suitable for annular forgings with the outer diameter size range phi of 1500-phi 1950mm and the height of less than or equal to 400mm, and the air cooling wind speed can adjust the size of the air source of the pressure pump with the adjustable air source according to needs.
