TECHNICAL FIELD
[0001] The utility model relates to material heat treatment technical field, concretely is a kind of heat treatment device for material research. BACKGROUND
[0002] In the material research process, heat treatment is undoubtedly a key core technology, it plays an irreplaceable decisive role in accurate control material microstructure and performance. However, traditional heat treatment device has some short boards in actual use process.
[0003] In the heating uniformity, its heating mode is relatively single. With the widely used electric heating wire heating mode as an example, electric heating wire is fixed in specific position, which leads to the distance between each part of material and electric heating wire is different. The part of distance is heated, and the part of distance is less heated, so that material heating degree presents obvious difference. Even if auxiliary blowing measure is adopted, it is intended to homogenize heat distribution by airflow, but due to airflow distribution is not easy to realize good cooperation with heating process, leading to the effect of final material all-around uniform heating is not ideal.
[0004] In the heating efficiency, traditional device is limited by established heating mode and self structure design. In the heat transfer process, path is long and transfer speed is slow, and material cannot be heated to target temperature quickly. In this way, the cycle required by heat treatment is greatly prolonged, the overall efficiency of material research is reduced, and the rapid advancement of research work is hindered. UTILITY MODEL CONTENT
[0005] The utility model aims at providing a kind of heat treatment device for material research to solve the problems raised in the above background technology.
[0006] To achieve the above object, the utility model provides the following technical scheme:
[0007] A kind of heat treatment device for material research, comprising:
[0008] Material heat treatment mechanism, including oven, the box door inner wall of the oven is located at center and is fixedly connected with placing table;
[0009] Surrounding heating mechanism, fixed on the outer wall of oven, can uniformly heat material;
[0010] Slip-in unit, rotates on the box door inner wall of oven, can heat the outer wall of material located on the side of oven door.
[0011] Further in: the surrounding heating mechanism includes:
[0012] Motor, with the outer wall of oven fixed connection, the rotating shaft of the motor is fixedly connected with round tube;
[0013] L-shaped pipes are arranged at one end of the circular pipe and fixed at equal angles.
[0014] Preferably, the surrounding heating mechanism comprises:
[0015] A ring holder one is fixed between the outer walls of the four L-shaped pipes, and the outer wall of the ring holder one is rotationally connected with the inner wall of the oven.

[0017] A rotary joint is fixedly connected between the stator and the outer wall of the oven, and the rotor is fixedly connected with the outer wall of the circular pipe.
[0018] Square holes one are arranged on the outer wall of the L-shaped pipe at equal intervals.
[0019] Preferably, the surrounding heating mechanism comprises:
[0020] A slip ring is fixedly connected between the stator and the outer wall of the oven, and the rotor is fixedly connected with the outer wall of the circular pipe.
[0021] An electric heating wire one is fixed in the L-shaped pipe, and one end of the electric heating wire one is fixedly connected with the rotor of the slip ring.
[0022] A guide vane one is fixed at one end of the electric heating wire one, and the outer wall of the guide vane one is fixedly connected with the inner wall of the L-shaped pipe.
[0023] Preferably, the sliding insertion unit comprises:
[0024] A ring holder two is rotationally connected with the outer wall of the oven door box.

[0027] Preferably, the sliding insertion unit comprises:
[0028] Square rods are arranged at two ends of the square tubes, and the outer wall of the square rod is slidably inserted into the outer wall of the L-shaped pipe.
[0029] Compared with the prior art, the utility model has the beneficial effects that:
[0030] 1. By driving the L-shaped tube and square tube to move around the material with the motor, and coordinating with the ejection of heating gas, the traditional method of heating with a single electric heating wire in a fixed position is changed. This creates a uniform high-temperature area around the material, which can quickly heat the material to the target temperature, greatly shortening the heat treatment cycle and improving the efficiency of material research.
[0031] 2. By inserting square tubes and L-shaped tubes, and electrically connecting guide plate one and guide plate two, the square tubes move along with the L-shaped tubes, allowing the hot airflow to act on the material from different angles. This effectively compensates for the uneven heating caused by the different distances between various parts of the material and the heating wire, achieving all-round uniform heating and improving the consistency of heat treatment effect.
[0032] 3. Through the square rod in the sliding unit, during the process of closing the oven door, the square rod slides along the outer wall of the L-shaped tube to guide the square tube to accurately insert into one end of the L-shaped tube. This ensures reliable contact between the guide plate inside the L-shaped tube and the connecting parts inside the square tube, guaranteeing circuit continuity and enabling the heating wire to heat up normally. This avoids heating abnormalities caused by inaccurate connection. Furthermore, when the oven door is opened and the square tube separates from the L-shaped tube, the square tube remains limited by the oven door, eliminating the need for manual re-alignment. The next time it is used, simply closing the oven door will automatically complete the connection, greatly improving operational convenience. Attached Figure Description
