The annealing furnace adopted is bottom-loading, and the lower furnace cover 44 is placed on the electric flat car 22, and the material rack 45 and the titanium wire disc to be annealed are placed on the lower furnace cover 44. The flat car is operated to travel to the bottom of the annealing furnace to complete the feeding, and the supporting slide 36 is supported on the bottom of the lower furnace cover 44. Then, the three-track hydraulic mechanism 3 is operated to drive the lower furnace cover 44 to move upward or downward to complete the loading and unloading steps. The material taking step is completed by the track platform 2 by itself, eliminating the process of crane lifting and taking materials, which can significantly improve the annealing efficiency and reduce labor costs.

[0030] The track platform 2 includes a ground rail 21, an electric flat car 22 and an electric track turntable 23. The electric flat car 22 rolls on the ground rail 21, and the electric track turntable 23 is installed at one end of the ground rail 21.

The guide rod 32 and the ball screw 33 are respectively installed on the support seat 31. The first hydraulic motor 34 is installed on one side of the support seat 31, and the output shaft of the first hydraulic motor 34 is connected to the gear shaft 35 through a gear. The gear shaft 35 is connected to the ball screw 33 through a gear. The support slide 36 is fixed on the nut seat of the ball screw 33. The slider of the linear guide 37 is fixedly connected to the support slide 36.

[0032] The bottom-loading resistance annealing furnace 4 includes a furnace body 41, a furnace lining 42, a heating resistance wire 43, a lower furnace cover 44, a material rack 45 and an upper furnace cover 46. The furnace lining 42 is attached to the inner wall of the furnace body 41, the heating resistance wire 43 is arranged between the furnace body 41 and the furnace lining 42, the material rack 45 is installed on the lower furnace cover 44, the lower furnace cover 44 is engaged with the bottom of the furnace body 41, and the upper furnace cover 46 is engaged with the top of the furnace body 41.

[0033] The furnace cover lifting mechanism 5 includes a second hydraulic engine 51, a ball screw pair 52 and a fixed steel frame 53. The output shaft of the second hydraulic engine 51 is connected to the ball screw pair 52 through a gear, and the fixed steel frame 53 is installed on the nut seat of the ball screw pair 52.

[0034] Specifically, the bottom of the bottom-loading resistance annealing furnace 4 is located below the operating platform 1, and the electric flat car 22 is located directly below the bottom of the bottom-loading resistance annealing furnace 4. In this embodiment, the resistance annealing furnace is a device that uses electrical energy for heat treatment. Its working principle is to convert electrical energy into thermal energy, heat the material to a certain temperature, and then slowly cool it, thereby improving the mechanical and physical properties of the material. The main functions of the operating platform 1 include equipment installation and maintenance, high-altitude operations, personnel operations, and material transportation, etc. Figure 2 As shown in FIG, the operating platform 1 is equipped with a ladder to provide workers with a safe, comfortable and convenient up and down passage, ensuring the safety of workers when working at height.

[0035] Specifically, the support seat 31 is fixed on the lower support column of the operating platform 1, and the support seat 31 is distributed in a triangular shape. In this embodiment, the support seat 31 is mainly used to connect the ball screw 33 and the first hydraulic engine 34 to ensure the stable operation and high-precision operation of the equipment. The first hydraulic engine 34 is an engine that uses liquid as a power transmission medium. It is mainly composed of components such as a hydraulic pump, a hydraulic motor and a hydraulic valve. Its working process is that first, the hydraulic pump extracts the liquid from the low-pressure area and compresses it into high-pressure liquid. Then, the high-pressure liquid enters the hydraulic motor through the hydraulic valve. The flow and pressure of the liquid cause the piston of the hydraulic motor to start moving, thereby driving mechanical movement. When the liquid flows in the hydraulic motor, the piston will continuously move back and forth, thereby generating continuous mechanical movement.

[0036] Specifically, the ball screw 33 is mounted on the support seat 31 through a bearing, and the gear shafts 35 are connected to each other through bevel gear transmission. Figure 4 As shown in FIG, when the first hydraulic motor 34 drives the gear shaft 35 to rotate, the ball screw 33 is driven to rotate under the meshing connection of the gears, thereby converting the rotational motion into linear motion, driving the supporting slide 36 to move up and down.

[0037] Specifically, the linear guide 37 is fixed to the lower support column of the operating platform 1, and the support slide 36 is located below the lower furnace cover 44. In this embodiment, the linear guide 37 mainly supports and guides the support slide 36 to perform reciprocating linear motion in a given direction, while also bearing a certain amount of torque, enabling high-precision linear motion under high load conditions.

[0038] Specifically, a bottom liner 47 is installed at the bottom of the furnace body 41, and is tightly joined to the lower furnace cover 44 via the bottom liner 47. In this embodiment, when the lower furnace cover 44 and the furnace body 41 are closed, the bottom liner 47 is used to ensure the sealing between the two.

[0039] Specifically, a top lining 48 is installed on the top of the furnace body 41, and is tightly joined to the upper furnace cover 46 via the top lining 48. In this embodiment, when the upper furnace cover 46 and the furnace body 41 are closed, the top lining 48 is used to ensure the sealing between the two.

[0040] Specifically, the second hydraulic motor 51 is fixed to the outer wall of the furnace body 41, and the ball screw pair 52 is fixed to the outer wall of the furnace body 41 via a bearing seat. In this embodiment, the second hydraulic motor 51 functions in the same way as the first hydraulic motor 34. Its operating principle is to convert liquid pressure into mechanical motion, thereby generating power, driving the ball screw pair 52 to convert rotational motion into linear motion, thereby driving the fixed steel frame 53 to move up and down.

[0041] Specifically, a clamping column 49 is provided on the top of the upper furnace cover 46, and an open ring 54 is provided on the upper portion of the fixed steel frame 53, and the open ring 54 is tightly engaged with the clamping column 49. In this embodiment, the cooperation between the open ring 54 and the clamping column 49 facilitates the connection between the fixed steel frame 53 and the upper furnace cover 46.

[0042] When the equipment of the present invention is in use, the annealing furnace adopted is a bottom-loading type, and the lower furnace cover 44 is placed on the electric flat car 22 (a logistics and transportation equipment powered by electricity, widely used in warehousing, logistics, manufacturing and other fields), and the material rack 45 and the titanium wire disc to be annealed are placed on the lower furnace cover 44, and the flat car is operated to travel to the bottom of the annealing furnace to complete the feeding, and the supporting slide 36 is supported on the bottom of the lower furnace cover 44. Then, the three-track hydraulic mechanism 3 is operated to drive the lower furnace cover 44 to move upward or downward to complete the loading and unloading steps, and the track platform 2 completes the material taking step by itself, eliminating the process of crane lifting to take the material, which can significantly improve the annealing efficiency and reduce labor costs. At the same time, it can also lay the foundation for the subsequent linkage of multiple annealing equipment to realize automatic loading and unloading.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
