It provides a tempering furnace that is easy to maintain. Through the optimized design of the tempering furnace structure, it is convenient to quickly inspect and replace the heating plate, improve maintenance efficiency, reduce maintenance costs, and effectively solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows:

[0005] A tempering furnace that is easy to maintain includes a furnace body and a furnace door that seals the furnace body. The furnace door is installed on the side wall of the furnace body via a rotating device, allowing the furnace door to be rotated to open and close. A locking device for opening and closing the furnace door is provided on the other side wall of the furnace body. A heating plate and a guide rail are provided inside the furnace body. The guide rail carries and guides the heating plate to move radially. An extension leg is provided below the heating plate.

[0019] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1 and 2As shown, the furnace body 1 and furnace door 2 are hexagonal in shape. The furnace body 1 serves as the main structure of the tempering furnace, used to accommodate workpieces to be tempered. Its internal space is designed according to actual usage requirements. The furnace door 2 is installed on the side wall of the furnace body 1 via a rotating device. The rotating device includes a rotating shaft 3 movably mounted on the side wall of the furnace body 1. One end of the rotating shaft 3 is fixedly connected to a rotating rod 5, and the other end of the rotating rod 5 is fixedly connected to the side wall of the furnace door 2, allowing the furnace door 2 to rotate and open and close around the rotating shaft 3. The rotation angle is 90° to 120°, facilitating loading and maintenance operations for operators. The other side wall of the furnace body 1 is equipped with a locking device for opening and closing the furnace door 2. The locking device adopts a lever-type locking structure, including a handle 4, a connecting rod 6, and a latch 7. When the furnace door 2 is closed, the operator moves the handle 4, causing the connecting rod 6 to move, so that the latch 7 engages in the corresponding locking groove of the furnace door 2, achieving a secure lock on the furnace door 2 and preventing the furnace door 2 from being accidentally opened during tempering, thus ensuring the safety of the tempering process.

[0021] like Figure 3-5 As shown, the furnace body 1 is equipped with a heating plate 8 and a guide rail 9. The guide rail 9 is fixedly installed on the inner bottom wall of the furnace body 1 and is a T-shaped guide rail. The two side walls of the guide rail 9 form guide grooves. A pulley 12 is provided below the heating plate 8. The pulley 12 is installed at the bottom of the heating plate 8 by a bracket. The groove of the pulley 12 is adapted to the guide groove of the guide rail 9, so that the pulley 12 can slide radially on the guide rail 9, thereby allowing the heating plate 8 to smoothly enter and exit the furnace body 1. An extension leg 10 is also provided below the heating plate 8. The extension leg 10 is movably located below the heating plate 8. When the heating plate 8 is moved out of the furnace body 1, the extension leg 10 is extended to support the heating plate 8 and keep it stable, which facilitates maintenance personnel to inspect, maintain and replace parts of the heating plate 8. When the furnace door 2 is closed, the heating plate 8 moves into the furnace body 1 and the extension leg 10 is retracted to avoid interference between the extension leg 10 and other components inside the furnace body 1. In addition, a heat-resistant caster wheel 11 is provided on one side of the extension leg 10. When the heating plate 8 is moved out of the furnace body 1, the position of the heating plate 8 can be easily adjusted by the caster wheel 11, which further improves the convenience of maintenance.

[0022] To improve the heat insulation performance and service life of the tempering furnace, a heat-resistant layer is provided on the inner wall of the furnace body 1. The heat-resistant layer adopts a multi-layer composite structure, consisting of a ceramic fiber felt layer, a rock wool board layer, and an aluminum silicate fiber board layer from the inside out. This effectively reduces heat loss, lowers the temperature of the outer wall of the furnace body 1, and protects the structure of the furnace body 1 from high-temperature damage.

[0023] The operation process of the tempering furnace of this utility model, which is easy to maintain, is as follows: The operator first opens the furnace door 2, releases the locking device by operating the handle 4, then rotates the furnace door 2 to a suitable angle, then moves the heating plate 8 out along the guide rail 9, and extends the extension leg 10 to support the heating plate 8. At this time, the heating plate 8 can be moved to the maintenance area, and the staff can also enter the furnace body 1 for cleaning. After completion, the heating plate 8 is moved into the furnace body 1, the extension leg 10 is retracted, the furnace door 2 is closed, and locked by the locking device.

[0024] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
