[0002] Vacuum heat treatment equipment is usually a vacuum furnace, which is an industrial furnace that performs heat treatment in a vacuum environment. The materials inside the furnace chamber are discharged through the vacuum system, so that the pressure inside the furnace chamber drops below a standard atmospheric pressure, thereby achieving a vacuum state. In this state, the workpiece can be heated by electric heating elements to achieve the desired heat treatment effect.

[0003] At present, when the mold steel material is subjected to vacuum heat treatment, the material is usually stacked inside the furnace body. Since the material is in a static state inside the furnace body, the contact surface of the material is not heated well due to the close fit between the materials. Relying solely on the physical properties of the material for heat conduction can easily cause uneven heating of the material, affecting the heat treatment effect of the mold steel material.

[0008] As a further solution of the utility model: a motor is fixedly connected to a side of the rotating drum away from the bearing seat, and an output end of the motor is installed in the bearing seat on the other side plate.

[0009] As a further solution of the utility model: a plurality of discharge valves are arranged outside the rotating drum, the discharge valves are located between two adjacent steel materials, and the number of each group of limit frames is two.

[0010] As a further solution of the utility model: support legs are respectively fixed on both sides of the bottom of the vacuum heating furnace, and a ventilation valve pipe is installed on the side of the vacuum heating furnace away from the vacuum pumping mechanism.

[0023] A support assembly 3 is fixed to one side of the sealing door 2 close to the inside of the vacuum heating furnace 1. The support assembly 3 includes two side plates 301. A plurality of fixing bars 302 are fixedly connected between the two side plates 301. A bearing seat 303 is installed on the side plate 301. One side of the rotating drum 401 is connected to the bearing seat 303. One of the side plates 301 is fixed to the sealing door 2. Since the bearing seat 303 is provided and one end of the rotating drum 401 is arranged inside the bearing seat 303, the purpose of supporting the rotating drum 401 is achieved, thereby improving the stability of the rotating drum 401 driving the steel material 8 to rotate and be heated.

[0024] A motor 304 is fixedly connected to one side of the rotating drum 401 away from the bearing seat 303 , and an output end of the motor 304 is installed in the bearing seat 303 on the other side plate 301 .

[0025] The support assembly 3 is internally installed with a mounting assembly 4, and the support assembly 3 and the mounting assembly 4 are located in the cavity of the vacuum heating furnace 1. The mounting assembly 4 includes a rotating drum 401, and a plurality of discharge valves 403 are provided outside the rotating drum 401. The discharge valves 403 are located between two adjacent steel materials 8, and the number of each group of limiting frames 6 is two. Due to the provision of the discharge valves 403, the granular steel materials 8 can be placed inside the rotating drum 401 for hot processing. After the discharge valves 403 are closed, the granular steel materials 8 will not separate from the rotating drum 401 during the movement.

[0026] The rotating drum 401 is arranged in the supporting assembly 3, a plurality of ventilation holes 402 are provided outside the rotating drum 401, two groups of limiting frames 6 are provided outside the rotating drum 401, slots 7 are provided inside the limiting frames 6, steel materials 8 are provided inside the two opposite slots 7, and the slots 7 inside the limiting frames 6 can limit the steel materials 8 through the mutual cooperation between the limiting frames 6 and the slots 7, so that two adjacent steel materials 8 do not contact each other, which is beneficial to the subsequent heating effect of the steel materials 8;

As the rotating drum 401 deflects, the steel 8 can slide out of the two limiting frames 6. When loading the steel 8, the steel 8 is inserted into the two opposite limiting frames 6, so that the slots 7 in the limiting frames 6 can limit the steel 8, and the limiting bolts 9 prevent the steel 8 from slipping off the rotating drum. 401, opening the discharge valve 403 can place the granular steel 8 or small parts inside the drum 401, and after pushing the drum 401 into the vacuum heating furnace 1 through the sealing door 2, the vacuum mechanism 10 performs vacuum treatment on the vacuum heating furnace 1.
