Description

Technical Field

[0001] This utility model relates to the field of lathe carriage processing technology, and in particular to a lathe carriage quenching structure. Background Art

[0002] When lathe parts are quenched, they need to be cleaned, preheated, heated, and then quenched.

[0003] The heat treatment involves placing the lathe parts into a quenching furnace and heating them for a certain time to bring the material to the required quenching temperature. The quenching treatment involves rapidly immersing the lathe parts in a quenching agent to cool the material quickly and form a high-strength, high-hardness microstructure.

[0004] Existing quenching heating equipment uses telescopic cylinders to push workpieces into the heating furnace. When handling heavy workpieces, this can easily cause wear on the transfer rollers, affecting subsequent workpiece transport. In addition, conventional heating furnaces heat the entire furnace at once, making it difficult to adjust the power according to the length of the workpiece, resulting in high energy consumption.

[0009] Multiple electric heating coils are evenly spaced inside the heating furnace;

[0010] The furnace conveying roller assembly includes multiple furnace conveying rollers evenly spaced within the heating furnace, and the electric heating coils are located between two of the furnace conveying rollers respectively;

[0011] A quenching agent pool is provided on the end side of the rear conveyor roller group, and a hoisting crane is provided above the rear conveyor roller group and the quenching agent pool.

[0012] Furthermore, the front-end conveying roller group includes multiple front-end conveying rollers mounted on the frame via bearing seats, and a front-end drive sprocket is provided at the shaft end of each front-end conveying roller, wherein the front-end drive sprocket is connected to the front-end drive motor via a chain.

[0013] A lathe pallet is conveyed on the front conveyor roller assembly.

[0014] Furthermore, the electric heating coils installed in the heating furnace are each independently temperature-controlled.

[0015] Furthermore, the furnace conveying roller assembly includes multiple furnace conveying rollers, with both ends of the furnace conveying rollers being installed inside the heating furnace via bearings. An external drive sprocket is installed at one end of the furnace conveying roller extending out of the outer wall of the heating furnace, wherein the external drive sprocket is connected to an external drive motor via a chain.

[0016] Furthermore, the rear conveyor roller assembly includes multiple rear conveyor rollers mounted on the frame via bearing seats, and a rear drive sprocket is provided at the shaft end of the rear conveyor rollers. The rear drive sprocket is connected to the rear drive motor via a chain.
