Technical Field

The heat treatment device for manufacturing metal components of a slipform paver, through the coordinated use of the heat treatment mechanism, the fixing mechanism and the positioning mechanism, constitutes an integrated automatic processing mode for the vibrating rods, so that the loading, fixing, feeding and transporting of the plurality of vibrating rods can be realized. The unloading operation is integrated and can be carried out continuously, which reduces waiting time and ensures the consistency of each operation. The adaptive positioning and straightening mechanism ensures the uniformity and quality of heat treatment and speeds up the processing time of a single piece. However, there are still some shortcomings in the application of this technical solution. The vibrating rod will produce granular impurities during the heat treatment process. If the granular impurities are not separated from the vibrating rod in time, the heat treatment effect of the vibrating rod will be affected, especially in the groove area. The granular impurities produced are easy to aggregate, reducing the heat transfer rate at this location. If the internal and external heating rates deviate greatly, it is easy to cause local overheating and generate large thermal stress, thereby causing problems such as cracking and deformation of the alloy.

[0017] Optionally, the interior of the driving shaft is configured as a hollow structure, a vibration shaft is rotatably connected to the interior of the driving shaft corresponding to the mesh cover, and an eccentric vibrator is mounted on the vibration shaft.

[0018] The present invention also provides a method for heat treatment of a metal material, comprising the following steps:

[0019] A hydraulic lifting mechanism for controlling the height of cylinder B is installed on the top of cylinder A, and a heat preservation pipe is installed between the air inlet pipe and the combustion furnace to introduce the high-temperature gas generated by the combustion furnace into the metal material heat treatment chamber formed by the combination of cylinder A and cylinder B along the tangential direction;

[0020] The end of the vibrating rod to be processed is placed against a plurality of fixed heads, and the vibrating rod is pressed down with force, so that the vibrating rod generates a lateral thrust on the fixed head. Under the action of the lateral thrust, the fixed head slides in the slide groove through the slider, and drives the support spring to undergo elastic deformation. After the vibrating rod is placed against the fixed seat, the elastically deformed support spring exerts an elastic force on the inner wall of the vibrating rod through the slider and the fixed head.

[0021] The hydraulic lifting mechanism is controlled to drive cylinder B to rise upward, and the support assembly loaded with a large number of vibrating rods to be processed is sent into cylinder A by using a manipulator and other related equipment. The support sleeve is mounted on the support frame to ensure the basic stability of the support assembly. After the manipulator moves out of cylinder A, the hydraulic lifting mechanism is controlled to drive cylinder B downward. During the downward process, cylinder B drives the drive shaft to move synchronously. The bottom end of the drive shaft is rounded, so that the bottom end of the drive shaft can easily enter the torsion groove, completing the combination of the drive shaft and the torsion shaft, releasing the high-temperature gas generated by the combustion furnace, and the high-temperature gas flows into the intake pipe along the insulation pipe, and the high-temperature gas enters the cylinder A and cylinder B along the intake pipe. When in the heat treatment chamber, the high-temperature gas will change from linear motion to circular motion. Most of the rotating airflow will flow spirally downward from the cylinder along the wall toward the conical cylinder. In addition, the particle impurities are thrown toward the wall under the action of centrifugal force. Once the dust particles contact the wall, they lose their inertial force, and the momentum of the downward axial velocity near the wall falls along the wall, enters the ash hopper, and falls into the collection bag through the sewage pipe. The rotating and descending external vortex airflow continuously flows into the center of the conical cylinder during the descent process, forming a centripetal radial airflow. This part of the airflow constitutes a rotating upward internal vortex. The rotation directions of the internal and external vortexes are the same. Finally, the purified gas is discharged from the device through the exhaust pipe.

[0022] The motor is controlled to run, and the motor output shaft drives the swing shaft B to rotate. The other end of the swing shaft B drives the driving gear to rotate through the linkage shaft and the swing shaft A. Under the action of the linkage shaft, the swing shaft A and the rocker shaft B, the driving gear performs forward and reverse motion, thereby driving the driven gear B to perform forward and reverse motion, and the driven gear B drives the driving shaft to perform forward and reverse motion. The driving shaft drives multiple active gear rings to perform forward and reverse motion at the same time through the torsion disk and the umbrella-shaped coupling shaft, and multiple active gear rings simultaneously drive multiple groups of driven gears A to perform forward and reverse motion, thereby driving the vibrating rod to perform forward and reverse motion.

[0023] The beneficial effect of the present invention is that the vibrating rod is heat treated during the process of the inner and outer swirls flowing through it, and the particulate impurities generated by the heat treatment of the vibrating rod can be separated from the vibrating rod. The generation of the inner and outer swirls will prolong the flow time of the high-temperature gas in the heat treatment chamber, which is beneficial to improving the utilization rate of the high-temperature gas, and also makes the evenly arranged vibrating rods heated evenly, thereby improving the heating uniformity of the vibrating rods while heat treating the vibrating rods in batches, and by quickly separating the particulate impurities from the vibrating rods, it is beneficial to further improve the uniformity of the heat treatment of the vibrating rods. The high-temperature gas acts on the vibrating rod in both directions, which can quickly fill the inside of the vibrating rod and avoid the outer wall of the vibrating rod being heated too quickly, resulting in local overheating and uneven heating temperature, thereby ensuring the uniformity of the heating temperature of the vibrating rod, giving enough time for the heat to be transferred and diffused more smoothly, and minimizing the adverse effects of thermal stress.

[0024] Multiple active gear rings simultaneously drive multiple sets of driven gears A to perform forward and reverse motion, thereby driving the vibrating rod to perform forward and reverse motion. During the forward and reverse motion of the vibrating rod, tangential force is generated with the internal and external swirls, which is beneficial to improving the cleaning effect of the high-temperature gas swirl on the particulate impurities on the vibrating rod.

[0025] The elastically deformed support spring applies elastic force to the inner wall of the vibrating rod through the slider and the fixed head, thereby ensuring the stability of the vibrating rod during heat treatment, allowing the vibrating rod to maintain a certain stability during rotation, and avoiding damage caused by collision between the vibrating rods.

10. A method for heat treatment of metal materials, applied to the metal material heat treatment device according to claims 1 to 9, characterized in that: The following steps are involved: A hydraulic lifting mechanism for controlling the height of cylinder B (304) is installed on the top of cylinder A (303), and a heat preservation pipe is installed between the air inlet pipe (306) and the combustion furnace (2) for introducing the high-temperature gas generated by the combustion of the combustion furnace (2) tangentially into the metal material heat treatment chamber formed by the combination of cylinder A (303) and cylinder B (304); The end of the vibrating rod to be processed is abutted against a plurality of fixed heads (4035), and the vibrating rod is pressed downward with force, so that the vibrating rod generates a lateral thrust on the fixed head (4035). Under the action of the lateral thrust, the fixed head (4035) slides in the slide groove through the slider (4033), and drives the support spring (4034) to undergo elastic deformation. After the vibrating rod abuts against the fixed seat (4032), the elastically deformed support spring (4034) exerts an elastic force on the inner wall of the vibrating rod through the slider (4033) and the fixed head (4035); The hydraulic lifting mechanism is controlled to drive the cylinder B (304) to rise upward, and a support assembly (4) loaded with a large number of vibrating rods to be processed is sent into the cylinder A (303) by using a manipulator and other related equipment. The support sleeve (402) is mounted on the support frame (7) to ensure the basic stability of the support assembly (4). After the manipulator is moved out of the cylinder A (303), the hydraulic lifting mechanism is controlled to drive the cylinder B (304) downward. During the downward movement, the cylinder B (304) drives the driving shaft (601) to move synchronously. The bottom end of the driving shaft (601) is rounded, so that the bottom end of the driving shaft (601) can easily enter the torsion groove, completing the combination of the driving shaft (601) and the torsion shaft, releasing the combustion furnace (2) to generate high-temperature gas, and the high-temperature gas flows into the intake pipe (306) along the insulation pipe, and the high-temperature gas is discharged along the intake pipe (3 06) When entering the heat treatment chamber formed by the combination of cylinder A (303) and cylinder B (304), the high-temperature gas will change from linear motion to circular motion. Most of the rotating airflow will flow along the wall from the cylinder in a spiral downward direction toward the conical cylinder (301). In addition, particulate impurities are thrown toward the wall under the action of centrifugal force. Once the dust particles contact the wall, they lose their inertial force and fall along the wall surface with the momentum of the downward axial velocity near the wall, enter the ash hopper (3021), and fall into the collection bag through the sewage pipe (3024). The rotating and descending external swirling airflow continuously flows into the central part of the conical cylinder (301) during the descent process, forming a centripetal radial airflow. This part of the airflow constitutes an internal swirling flow that rotates upward. The rotation directions of the internal and external swirling flows are the same. Finally, the purified gas is discharged from the device through the exhaust pipe (307); The motor (602) is controlled to operate, and the output shaft of the motor (602) drives the swing shaft B (6035) to rotate. The other end of the swing shaft B (6035) drives the driving gear (6032) to rotate through the linkage shaft (6034) and the swing shaft A (6033). Under the action of the linkage shaft (6034), the swing shaft A (6033) and the rocker shaft B, the driving gear (6032) performs forward and reverse motion, thereby driving the driven gear B (6031) to perform forward and reverse motion. The driven gear B (6031) drives the driving shaft (601) to perform forward and reverse motion. The driving shaft (601) simultaneously drives the plurality of driving gear rings (502) to perform forward and reverse motion through the torsion plate (504) and the umbrella-shaped coupling shaft (503). The plurality of driving gear rings (502) simultaneously drive the plurality of groups of driven gears A (501) to perform forward and reverse motion, thereby driving the vibrating rod to perform forward and reverse motion.
