Description

Technical Field

[0001] The utility model relates to the field of tempering furnaces, and particularly to a hoisting tool for a tempering furnace. Background Art

[0002] The tempering furnace is an important device in the heat treatment process, used for tempering metal workpieces to eliminate the internal stress and brittleness generated during the quenching process, and improve the toughness and stability of the workpieces. In the heat treatment industry, the workpieces to be processed are diverse in types, sizes and weights, which poses diverse requirements for the design of hoisting tools.

[0003] At present, the hoisting methods often rely on manual handling and hoisting of workpieces, with high labor intensity and low efficiency. Manual operation may have potential safety hazards during hoisting, such as accidents like workpiece slipping and collision. During the tempering process, residues may be generated on the workpieces. If these residues directly fall into the tempering furnace, they will affect the cleanliness and working environment of the furnace. Summary of the Utility Model

[0004] In order to overcome the above deficiencies, the utility model provides a hoisting tool for a tempering furnace.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A hoisting tool for a tempering furnace includes a tempering furnace and a lifting device. The lifting device is located outside the tempering furnace. The lifting device includes a base, and several legs are fixedly connected to the outer wall of the base. The top of the base has a rotating platform, the bottom of the rotating platform is rotatably connected to the top of the base, a support shaft is fixedly connected to the center of the bottom of the rotating platform, the support shaft penetrates the base and is rotatably connected to the base. A servo motor is fixedly installed inside the bottom of the base, and the top end of the output shaft of the servo motor is fixedly connected to the bottom end of the support shaft. The top of the rotating platform is fixedly connected to the bottom of the cylinder barrel of an electric cylinder, the top end of the piston rod of the electric cylinder is fixedly connected to a lifting arm. The bottom of the front end of the lifting arm is rotatably connected to a hook. Below the hook, there is a hanging rod. The top end of the hanging rod is fixedly connected to a hanging ring, and the hanging ring is hooked to the hook. The hanging rod penetrates through the centers of several trays, and the outer wall of the hanging rod is fixedly connected to several trays. The trays are evenly distributed at equal intervals up and down. The trays are centered on the hanging rod, and the outer edge of the tray wall protrudes upward.

[0007] The lifting arm includes a first cylinder, a second cylinder and a third cylinder. The first cylinder is fixedly connected to the top of the piston rod of the electric cylinder. The upper part of the first cylinder is fixedly connected to one end of the second cylinder. The other end of the second cylinder is perpendicularly and fixedly connected to the upper part of the third cylinder. The third cylinder is vertically downward, and the lower part of the third cylinder is rotatably connected to one end of the hook.

[0008] The beneficial effects of the utility model are as follows:

[0009] The utility model realizes the hoisting and rotation of workpieces through electric control, greatly reducing the labor intensity of workers and improving the feeding efficiency. The design of the tray can effectively receive the residues generated during the tempering process, preventing the residues from directly falling into the tempering furnace, thereby protecting the cleanliness and service life of the tempering furnace.

[0013] As Figure 1-2 shown: A hoisting tool for a tempering furnace includes a tempering furnace 1 and a lifting tool; the lifting tool is located outside the tempering furnace 1. The lifting tool includes a base 2, and a plurality of support legs 12 are fixedly connected to the outer wall of the base 2. The top of the base 2 has a rotating table 3, the bottom of the rotating table 3 is rotatably connected to the top of the base 2, the center of the bottom of the rotating table 3 is fixedly connected with a support shaft 4, the support shaft 4 penetrates through the base 2 and is rotatably connected with the base 2, a servo motor 5 is fixedly installed on the inner side of the bottom of the base 2, and the top end of the output shaft of the servo motor 5 is fixedly connected with the bottom end of the support shaft 4. The top of the rotating table 3 is fixedly connected to the bottom of the cylinder barrel of the electric cylinder 6, the top end of the piston rod of the electric cylinder 6 is fixedly connected with a lifting arm 7, the bottom of the front end of the lifting arm 7 is rotatably connected with a hook 8, a suspension rod 9 is arranged below the hook 8, the top end of the suspension rod 9 is fixedly connected with a lifting ring 10, the lifting ring 10 is hooked with the hook 8, the suspension rod 9 penetrates through the centers of a plurality of trays 11, the outer wall of the suspension rod 9 is fixedly connected with a plurality of trays 11, the trays 11 are evenly distributed at equal intervals up and down, the trays 11 are centered on the suspension rod 9, and the outer wall edge of the tray 11 protrudes upward.

[0014] The lifting arm 7 includes a cylinder one 701, a cylinder two 702 and a cylinder three 703. The cylinder one 701 is fixedly connected to the top of the piston rod of the electric cylinder 6, the upper part of the cylinder one 701 is fixedly connected to one end of the cylinder two 702, the other end of the cylinder two 702 is vertically and fixedly connected to the upper part of the cylinder three 703, the cylinder three 703 is vertically downward, and the lower part of the cylinder three 703 is rotatably connected to one end of the hook 8.

[0015] First, the hook 8 is hooked to the hanging ring 10, and the workpiece to be tempered is placed on the tray 11. The tray 11 is outside the tempering furnace 1. The design of the tray 11 enables the workpiece to be placed stably. At the same time, the upward protrusion on the outer wall edge of the tray 11 helps to prevent the workpiece from slipping during movement. The trays 11 are evenly distributed at equal intervals, ensuring the uniform loading and stability of the workpiece.

[0016] The worker controls the electric cylinder 6 to extend the cylinder 701 downward, and the entire tray 11 enters the tempering furnace 1. The servo motor 5 drives the rotating table 3 to rotate through the support shaft 4, and then drives the entire lifting tool system (including the electric cylinder 6, the lifting arm 7, the hook 8, the suspension rod 9 and the workpiece on the tray 11) to rotate. This step helps to adjust the angle and position of the workpiece entering the tempering furnace 1, ensuring the safety and smoothness of the lifting process.

[0017] Under the coordinated action of the servo motor 5 and the electric cylinder 6, the lifting tool system slowly sends the workpiece into the tempering furnace 1. During this process, the tray 11 not only bears the workpiece, but also plays a role in receiving the residues that may be generated during the tempering process, effectively preventing the residues from directly falling into the tempering furnace, thereby protecting the cleanliness and working environment of the tempering furnace. The present utility model only protects the mechanical part, and the functions realized by the software control part related thereto are not within the protection scope of the present utility model.
