Technical Field

[0001] The invention relates to the technical field of forging, in particular to a pipeline air cooling device for forgings. Background Art

[0002] In the forging industry, a large amount of heat is still stored inside the forging after the forging process. The subsequent cooling process has an important influence on the organizational structure, performance and dimensional accuracy of the forging. Traditional post-forging air cooling mostly adopts a simple method of direct fan blowing. In this way, the airflow blown by the fan directly acts on the surface of the forging, and the heat of the forging is taken away by accelerating the flow of air, thereby achieving a cooling effect. However, this seemingly convenient cooling method has many limitations. For example, due to the uneven distribution of the air blown by the fan in space, there are obvious differences in the cooling rates of different parts of the forging, which may cause a large temperature difference inside the forging, thereby generating large thermal stress, which will not only cause the forging to deform, but also crack in severe cases, greatly affecting the dimensional accuracy and quality stability of the forging. At the same time, the cooling rate of the air cooling method that relies solely on direct fan blowing is also difficult to accurately control, and cannot meet the production needs of some special forgings that have strict requirements on the cooling process, which to a certain extent limits its scope of application and the quality improvement space of forging production.

[0017] Among them, the placement table 1 is used to place the forged forgings, which is a rectangular platform made of steel; the fan 2 is installed 1.5-2m above the placement table 1, and the fan 2 can be fixed on the floor of the workshop through a support frame. The power of the fan 2 needs to be selected according to the size of the forging (5-10kW is recommended), and the diameter of the air outlet matches the air outlet hood 3. The air outlet hood 3 is cylindrical in shape, and the air outlet hood 3 is detachably connected to the outer wall of the fan 2 through a snap-on interface, or connected to the outer wall of the fan 2 by bolt connection. At least two air ducts 4 made of high-temperature resistant corrugated hoses are selected, and one end of the air duct 4 is sealed and fixed to the air outlet hood 3 through a flange to ensure that it is connected to the inner cavity of the air outlet hood 3. The length of the air duct 4 is set according to the distance between the air outlet hood 3 and the placement table 1, preferably 2-3m. The fixing seat 5 is installed on the outside of the placing platform 1 by means of anchor bolts. It should be noted here that multiple fans 2 can be set according to the size of the placing platform 1, and each fan 2 corresponds to a fixing seat 5; the connecting rod 6 can be rotatably connected to the fixing seat 5 by means of a hinge, so that the air duct 4 can be driven to rotate in the horizontal plane to adjust the position of the air outlet of the air duct 4.

[0018] In order to prevent the end of the air guide 4 from swinging when the air guide 4 is discharging air, further, see Figure 1-Figure 3 The air duct 4 is a corrugated hose, and the end of the air duct 4 away from the air outlet shield 3 is fixedly connected with a mounting tube 7, and the mounting tube 7 is sleeved on the air duct 4. The connecting rod 6 is connected to the mounting tube 7 through a rotating mechanism, and the rotating mechanism includes a rotating groove 8 provided at the end of the connecting rod 6, and a rotating head 9 is provided in the rotating groove 8. The rotating head 9 is fixedly connected to the mounting tube 7, and the rotating axis of the rotating head 9 is perpendicular to the axis of the mounting tube 7. Among them, the mounting tube 7 can be sleeved on the air duct 4 by bolt connection, and the rotating groove 8 is a cylindrical cavity. The rotating head 9 includes a cylindrical platform and a rotating rod provided in the rotating groove 8. The rotating rod and the cylindrical platform are integrally formed, and the rotating groove 8 at the end of the connecting rod 6 is engaged with the rotating head 9 on the mounting tube 7. The axis of the rotating head 9 is perpendicular to the axis of the mounting tube 7, so that the air duct 4 can be adjusted in pitch in the vertical direction.

[0019] In the above embodiment, the locking is performed by the friction between the rotating groove 8 and the rotating head 9, which is easy to loosen. Figure 3 The outer surface of the connecting rod 6 is provided with a threaded hole 10 communicating with the inner cavity of the rotating groove 8, and a locking screw 11 is provided in the threaded hole 10. The locking screw 11 is screwed into the threaded hole 10 on the outer surface of the connecting rod 6, and the current air outlet angle of the air guide 4 is fixed by tightening the screw against the rotating head 9.

[0020] For further information, see Figure 2 , each of the connecting rods 6 is provided with a rotating seat 12, the rotating axis of the rotating seat 12 is perpendicular to the axis of the connecting rod 6, and a plurality of the rotating seats 12 are arranged at intervals on the top of the fixed seat 5 and connected to the fixed seat 5 through bearings. The rotating seat 12 is installed on the top of each fixed seat 5 through a bearing. In this way, the connecting rod 6 can be better rotated in the horizontal plane. In the specific use process, the placement table 1 is divided into a plurality of non-overlapping areas according to the number of air ducts 4, and each area corresponds to an air duct 4, which can also prevent interference between the air ducts 4.

[0021] In order to adjust the relative position of the air duct 4 and the placement table 1, further, see Figure 1 and Figure 2 A telescopic mechanism 13 is provided between the connecting rod 6 and the rotating seat 12. A hydraulic or threaded telescopic mechanism 13 is installed between the connecting rod 6 and the rotating seat 12, and the adjustment range is 200-500mm, which is used to adjust the relative position of the air guide 4 and the placement table 1.

[0022] In order to adjust the air volume of the air guide 4, further refer to Figure 1 The end of the air duct 4 away from the air outlet shield 3 is provided with a regulating valve 14. A butterfly valve is installed at the end of each air duct 4 (close to the side of the placement table 1), and the valve opening is controlled by a manual knob to achieve graded air volume regulation.

[0023] To achieve better heat dissipation, see Figure 1 The placing table 1 is a hollow structure. A plurality of grooves are arranged along the width direction of the placing table 1, so that after the forging is placed on the placing table 1, cold air can enter the grooves at the bottom of the forging to cool the bottom of the forging.

[0024] During specific use, the forging is placed on the placement table 1, and the area of ​​the forging with thicker thickness is determined according to the shape of the forging. The rotating seat 12 is rotated and the length of the telescopic mechanism 13 is adjusted so that the outlet of the air duct 4 is opposite to the thicker area. The regulating valve 14 is used to adjust the air volume of the air duct 4 to cool down the thicker area. For forgings with grooves that are not opposite to the air duct 4, the air outlet of the air duct 4 can be made opposite to the groove by rotating the rotating head 9 in the rotating groove 8 to avoid heat accumulation in the groove.
