[0002] A tempering furnace is a heat treatment equipment used to improve the hardness and mechanical properties of steel materials, mainly used in fields such as metal processing, forging, and casting. By heating the steel to a certain temperature (usually between 200 - 1100 °C), then maintaining for a certain period of time, and finally rapidly cooling, the purpose of softening the steel and making it easy to process is achieved.
[0003] However, the following problems still exist in the actual operation process: During the process of tempering and softening steel using a tempering furnace, since the internal temperature needs to ensure that the steel is heated between 200 - 1100 °C, the steel cannot be taken out immediately after the tempering and softening operation. And due to the accumulation of internal temperature, the temperature change is slow. If it cannot be taken out in time, the overall processing efficiency will be low.
[0004] Based on this, the utility model provides a tempering furnace for steel heat treatment. Content of the Utility Model
[0005] Aiming at the deficiencies of the prior art, the utility model provides a tempering furnace for steel heat treatment, which has the advantages of a pop-up type for assisting in taking out steel and an adjustable distance type for adjusting the placement space according to the size of the steel, and solves the problems raised in the background technique.
[0006] The utility model provides the following technical solution: A tempering furnace for steel heat treatment, including a main body. Inside the cavity of the main body, four groups of sliding sleeve shells are fixedly installed. Inside the four groups of sliding sleeve shells, auxiliary wheels are arranged. Inside the auxiliary wheels, a connecting shaft is fitted. On the surface of the connecting shaft, two groups of connecting plates are fixedly installed. On the top of the two groups of connecting plates, a bracket frame is fixedly installed. On both sides of the inner wall of the bracket frame, inner measuring plates are respectively arranged. On the top of the inner measuring plates, clamping columns are fixedly installed. On the surface of the clamping columns, clamping plates are fitted. On the side of the clamping plates, a steel placement rack is fixedly installed. A number of heat dissipation holes are opened at the bottom end of the steel placement rack.
[0007] Preferably, two groups of clamping inserts are fitted on the surface of the sliding sleeve shell. On the side of the two groups of clamping inserts, a fixing plate is fixedly installed. On the side of the fixing plate, a strong spring is fixedly installed. On the other side of the strong spring, a contact plate is fixedly installed. On the other side of the contact plate, it is in contact with the auxiliary wheel.
[0008] Preferably, the outer sides of the connecting plate and the connecting shaft are in a horizontally aligned state, and the outer sides of the connecting plate and the connecting shaft are in contact with the inner wall of the main body.
[0009] Preferably, a sliding sleeve is attached to the side of the bracket frame, and a clamping insert is attached to the inside of the bracket frame.
