Description

Technical Field

[0001] This utility model relates to the field of mold steel technology, and specifically to a mold steel quenching device. Background Technology

[0002] like Figure 1 The diagram shows the structure of a mold steel block. Mold steel quenching is a heat treatment process in which the mold steel is heated to above the critical temperature, held at that temperature for a certain time, and then cooled at a rate greater than the critical cooling rate to obtain a non-equilibrium structure dominated by martensite (sometimes bainite or single-phase austenite can also be obtained as needed).

[0003] The main purpose of quenching is to improve the microstructure of mold steel and enhance its mechanical properties. Specifically, quenching can transform supercooled austenite into martensite or bainite, thereby significantly improving the hardness, strength, wear resistance, and fatigue strength of mold steel. Furthermore, quenching can improve the toughness of mold steel, making it less prone to fracture when subjected to impact and vibration.

[0004] Because the quenching time (alternating water and air) for large-size mold steel is relatively long, about 2 to 3 hours, the original method of using overhead cranes to transport the mold steel for quenching would significantly reduce the crane's operating time. Furthermore, if multiple overhead cranes are used in the same workshop, and one crane remains stationary at a certain position for too long, it can cause production stoppages and accidents. Utility Model Content

[0007] The quenching pool has support parts on both sides;

[0008] The hoisting mechanism is always positioned directly above the quenching tank;

[0009] The hoisting mechanism includes a hoisting frame and two lifting modules;

[0016] In the two lifting modules, the winches on each shaft correspond one-to-one with the winches on the other shaft, and the same lifting chain is connected to each pair of corresponding winches; the motor is used to drive the shaft to rotate.

[0017] Preferably, the support portion of the quenching pool is provided with a limiting groove, which is adapted to the supporting vertical plate of the hoisting frame.

[0021] After the overhead crane transports the hoisting frame carrying the mold steel to the quenching tank, it can be separated from the hoisting frame.

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This embodiment of a mold steel quenching device includes a quenching tank 1 and a hoisting mechanism.

[0028] like Figure 2 As shown, the quenching pool 1 has support parts 2 on both sides.

[0029] The hoisting mechanism is always located directly above the quenching tank 1; the hoisting mechanism includes a hoisting frame 3 and two lifting modules;

[0030] like Figure 3As shown, the bottom sides of the hoisting frame 3 are symmetrically provided with support vertical plates 4, which are directly opposite the support part 2; the top of the hoisting frame 3 is provided with lifting lugs 5.

[0031] like Figure 4 As shown, two lifting modules are symmetrically arranged on the top sides of the hoisting frame 3; each lifting module includes a rotating shaft 6, several winches 7, and a motor 8; the rotating shaft 6 is horizontally rotatable on the top of the hoisting frame 3; several winches 7 are equally spaced and fixed on the rotating shaft 6; in the two lifting modules, the winches on each rotating shaft correspond one-to-one with the winches on the other rotating shaft, and the same lifting chain 9 is connected to each pair of corresponding winches; the motor 8 is used to drive the rotating shaft to rotate.

[0032] During quenching, the mold steel is first transferred to all the lifting chains 9. Then, the overhead crane uses the lifting lugs 5 of the lifting frame 3 to transfer the lifting frame containing the mold steel to the top of the quenching tank 1. The overhead crane then places the lifting frame 3 on the support part 2 of the quenching tank 1 and moves away. Then, according to the quenching process requirements, the winch 7, driven by the motor 8, lowers and lifts the mold steel to complete the quenching process of the mold steel. After the process is completed, the overhead crane lifts away the lifting frame.

[0033] In this embodiment, as Figure 2 As shown, each of the support parts 2 of the quenching pool 1 is provided with a limiting groove 10, which is adapted to the support vertical plate 4 of the hoisting frame 3; this setting can more stably support the hoisting frame 3 and improve safety.

[0034] In this embodiment, a reduction gearbox (not shown in the figure) is connected to the motor 8. The motor 8 is connected to the rotating shaft 6 through the reduction gearbox, which can effectively control the lifting speed of the mold steel, making it rise and fall smoothly and improving safety.

[0035] In this embodiment, the motor 8 is provided with a heat insulation cover (not shown in the figure) to protect the motor 8.

[0036] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described.
