Description

Technical Field

[0001] The utility model relates to the technical field of casting heat treatment equipment, in particular to a casting heat treatment device. Background Art

[0002] In order to improve the structural quality of castings, it is often necessary to use heat treatment equipment to perform heat treatment on castings. The utility model patent with patent application number CN202321679282.3 discloses a casting heat treatment device. By starting the No. 1 motor, the rotating shaft of the No. 1 motor drives the rotating rod to rotate through the bevel gear. The rotating rod drives the rocking plate at the lower end to rotate, so that the sliding frame rolls left and right on the fixed beam. The No. 2 motor is controlled so that the rotating shaft of the No. 2 motor drives the eccentric wheel to rotate. The rotation of the eccentric wheel can make the pull rod pull the vertical plate to swing, thereby making the shaft connecting rod swing. The two sets of axial connecting rods are connected by a connecting rod to achieve simultaneous swing of the two sets of axial connecting rods, thereby making the nozzle swing and making the casting heated evenly. According to the technical solution disclosed therein, when the existing casting heat treatment equipment is used, on the one hand, when performing cooling work, it is often impossible to ensure that the cooling speed is uniform and stable, and the quality of the casting is easily affected by insufficient cooling speed or too fast cooling speed. On the other hand, when adjusting the cooling speed, it is easy to cause excessive changes in the air flow due to the sudden start and stop of the fan, which is not conducive to ensuring the smooth adjustment of the cooling speed.

[0003] Therefore, how to design a casting heat treatment device has become our current problem to be solved. Utility Model Content

[0010] Furthermore, the air pipe is installed on the top of the box body by bolts, the bottom end of the air pipe passes through the top of the box body and the air duct and extends to the bottom of the air duct, and the valve is installed on the air pipe.

[0011] Furthermore, a card cover is welded to the outer side of the trachea, and the card covers are respectively located on both sides of the trachea.

[0013] The heated air flows through the duct to the top of the support plate, thereby cooling the casting and avoiding direct contact of the high-temperature casting with the cold air, thereby causing the material to produce large internal stress, thereby ensuring the quality of the casting. The air heated by the casting is discharged outwards through the air pipe, and the motor drives the fan blades to rotate, thereby improving the internal circulation in the box and ensuring that the temperature of the casting is more uniform during heating and cooling.

When the fan 13 is turned on or off, The air flow velocity in the box body 1 increases and then decreases. When the air flow in the air pipe 9 flows, it is necessary to push the impeller 20 to rotate, and then the impeller 20 in the card cover 19 drives the counterweight 21 to rotate. When the air flow suddenly increases or decreases, the impeller 20 will slowly increase or decrease under the inertia of the counterweight 21, and then the air flow velocity in the box body 1 will change slowly, avoiding excessive changes in the air flow velocity due to sudden opening or closing of the fan 13, and thus being able to smoothly adjust the cooling speed to ensure the quality of the casting.

The fan 13 is mounted on the inner side of the air duct 11 by means of bolts, and a valve 12 is mounted on the bottom of the air duct 11. The motor 17 is mounted on one side of the box body 1 by means of bolts, and the fan blades 18 are mounted on the inner side of the box body 1. One end of the fan blade 18 passes through the inner wall of the box body 1 and is keyed to the output shaft of the motor 17.

After the temperature is kept constant for a required time, the casting is cooled. The valve 10 and the valve 2 12 are opened and the ventilation speed is adjusted by the valves 10 and 12. The cold air enters the air duct 14 through the air duct 11 and heat is exchanged through the air duct 14, so that the cold air is heated and the air in the box body 1 is cooled. The heated air is discharged to the top of the support plate 3 through the opening 15 and the pores 16. The air flows in the box 1 to cool the casting, avoiding high-temperature castings from directly contacting cold air and causing large internal stress in the material, thereby ensuring the quality of the casting. The air heated by the casting is discharged outward through the air pipe 9, and the motor 17 drives the fan blades 18 to rotate, thereby improving the internal circulation in the box 1 and ensuring a more uniform temperature during heating and cooling of the casting. When the cooling speed is insufficient, the fan 13 is turned on to increase the air flow speed in the box 1, thereby increasing the cooling speed of the casting. The cooling speed can be adjusted according to the different requirements of heat treatment such as annealing and normalizing, thereby ensuring the processing quality of the casting.

The cold air enters the air duct 14 through the air tube 11, and heat exchange is performed through the air duct 14, so that the cold air is heated and the air in the box body 1 is cooled. The heated air flows to the top of the support plate 3 through the through port 15 and the pores 16 to cool the casting, avoid high-temperature castings directly contacting the cold air and causing large internal stress in the material, and ensure the quality of the casting. The air heated by the casting is discharged outward through the air pipe 9, and the motor 17 drives the fan blades 18 to rotate, thereby improving the internal circulation in the box body 1 and ensuring the quality of the casting. The temperature during heating and cooling is more uniform. When the cooling speed is insufficient, the fan 13 is turned on to increase the air flow speed in the box 1, thereby increasing the cooling speed of the casting. The cooling speed can be adjusted according to the different requirements of heat treatment such as annealing and normalizing, thereby ensuring the processing quality of the casting. When the fan 13 is turned on or off, the air flow speed in the box 1 increases and then decreases. When the air flow in the air pipe 9 flows, it is necessary to push the impeller 20 to rotate, and then the impeller 20 in the card cover 19 drives the counterweight 21 to rotate.
