Description

Technical Field

[0001] The invention relates to the technical field of forging processing, in particular to a heat treatment device for processing shaft forgings. Background Art

[0002] The processing of shaft forgings is a key link in the field of mechanical manufacturing. Shaft forgings are used to support transmission parts, transmit torque and bear loads. There are many types such as smooth shafts and stepped shafts. Carbon steel, alloy steel and other materials are often used. The processing process includes preparing suitable steel first to ensure that the quality and size specifications meet the requirements. After heating the raw materials to the forging temperature range, they are forged by forging equipment using upsetting, drawing and other processes. After forging, they are normalized or annealed to eliminate stress and refine grains. Some parts also need quenching and tempering to obtain good performance. Then they are machined. First, rough machining is performed to remove the excess, and then fine machining is performed to improve the accuracy. After that, the surface is galvanized, nitrided and other treatments are performed according to the use requirements. Finally, the dimensional accuracy, mechanical properties, etc. are fully inspected. The forging ratio should be reasonably controlled to improve the metal structure performance. The heat treatment process should be selected according to the material and use requirements. Appropriate equipment and methods are used to ensure the processing accuracy. Measures are taken to control the surface quality to improve the wear resistance, corrosion resistance and fatigue performance of shaft forgings. In the prior art, during the quenching process of large shaft forgings, a large number of high-temperature workpieces continuously enter the quenching pool, which will cause the oil temperature to continue to rise. The cooling effect of the traditional quenching pool is poor, resulting in the cooling medium being unable to dissipate heat in a timely and effective manner. When the oil temperature exceeds a certain range, the cooling capacity of the cooling medium will significantly decrease, thereby affecting the cooling effect. Before the shaft forgings enter the quenching pool, the iron oxide impurities on the surface will fall off and enter the quenching oil during the quenching process. The impurities will continue to accumulate in the pool, causing the fluidity of the oil to deteriorate, affecting the cooling effect. Summary of the invention

The lifting equipment clamps the workpiece inside the mobile platform in the heat treatment equipment and transports it to the forging equipment so that it can forge the heated blank. During the forging process, the first pump body pumps the quenching oil pre-stored in the quenching oil storage tank into the supply pipe along the corresponding pipeline, and then discharges it into the water tank through the supply pipe to fill the quenching oil to the specified liquid level height position. The lifting equipment moves the workpiece after heat treatment in the heat treatment equipment into the water tank, and quickly cools the workpiece with the quenching oil.

The first electric telescopic rods on the front and rear sides drive the second filter plate to move above the Z-shaped conveyor. The second electric telescopic rods on the front and rear sides drive the rotating rods at the corresponding positions to rotate upward on the inner side of the base frame, so that the roller shaft contacts the left side of the lower surface of the second filter plate and lifts up the lower left side of the second filter plate.
