Description

Technical Field

[0001] The utility model relates to the technical field of annealing equipment, in particular to an annealing equipment for excavator bucket teeth. Background Technique

[0002] Annealing is a metal heat treatment process, which means heating the metal slowly to a certain temperature, maintaining for a sufficient time, and then cooling at an appropriate speed to change the microstructure of the material, and further change its mechanical properties (such as hardness, strength, etc.). The purposes of annealing include but are not limited to releasing stress, increasing the ductility and toughness of the material, generating special microstructures, etc. Annealing processes include full annealing, spheroidizing annealing, isothermal annealing, graphite annealing, diffusion annealing, stress relief annealing, incomplete annealing, post-weld annealing, etc. Each type has its specific application scenarios and purposes.

[0003] For example, Chinese Patent CN212713667U discloses an annealing equipment for excavator bucket teeth, which includes an annealing furnace.

[0004] However, in the prior art, during the annealing process of excavator bucket teeth using multiple electric heating tubes, as the excavator bucket teeth are annealed and heated up, since the distance between the excavator bucket teeth and the electric heating tubes is fixed, the temperature of each point on the excavator bucket teeth close to the electric heating tubes rises rapidly, while the temperature of other parts far from the electric heating tubes does not rise rapidly. As a result, it is difficult to maintain good uniformity of the heating temperature of the excavator bucket teeth. Using the existing annealing equipment for annealing excavator bucket teeth has a poor effect, and the annealing effects at different positions of the annealed excavator bucket teeth are uneven, making it difficult to achieve the required mechanical properties. At the same time, the existing annealing equipment cannot perform local heating and annealing processing on the excavator bucket teeth according to the required annealing temperatures of different parts of the excavator bucket teeth. To address the above problems, an annealing equipment for excavator bucket teeth is proposed. Content of the Utility Model

[0023] The following specifically describes the specific settings and functions of this embodiment: When the moving frame 12 drives the excavator bucket tooth into the heating frame plate 21, the adjusting motor 25 is controlled to start through the annealing controller 22. The adjusting motor 25 drives the adjusting screw rod 26 to rotate, driving the moving block 27 to move left and right along it.

[0024] Embodiment 2: As Figure 1 and Figure 2As shown in the figure, the mobile device 1 includes a base 11, a mobile frame 12, a support frame 13, a first hydraulic cylinder 14, a second hydraulic cylinder 15, a third hydraulic cylinder 16, a lead screw 110 and a lead screw motor 111.

[0025] The effect achieved by the entire embodiment is that when using this device to anneal the bucket teeth of an excavator, first place the bucket teeth of the excavator to be annealed on the top end of the mobile frame 12, turn on the lead screw motor 111 and the annealing controller 22. The annealing controller 22 controls multiple heating plates 23 to quickly and evenly preheat the heating frame plate 21. The lead screw motor 111 drives the lead screw 110 to rotate, and the mobile frame 12 moves along the base 11. When the mobile frame 12 moves to the feeding port, the first hydraulic cylinder 14 drives the feeding plate 17 to move upward to open, and the mobile frame 12 drives the bucket teeth of the excavator to move into the heating frame plate 21, and then the first hydraulic cylinder 14 drives the feeding plate 17 to move downward to close. When the mobile frame 12 drives the bucket teeth of the excavator to move into the heating frame plate 21 for heating and annealing, after the heating and annealing are completed, the second hydraulic cylinder 15 drives the sealing plate 18 to move upward to open, the lead screw motor 111 continues to drive the lead screw 110 to rotate, and the mobile frame 12 continues to drive the bucket teeth of the excavator to move into the cooling device 112 for cooling. After the cooling is completed, the controller controls the third hydraulic cylinder 16 to open, and the third hydraulic cylinder 16 drives the discharging plate 19 to move upward to open, thereby completing the entire annealing process of the bucket teeth of the excavator.

[0026] Usage method and working principle of this device: When annealing the bucket teeth of an excavator using this device, first place the bucket teeth of the excavator to be annealed on the top of the moving frame 12, and turn on the lead screw motor 111 and the annealing controller 22. The annealing controller 22 controls multiple heating plates 23 to heat the inside of the heating frame plate 21, which can quickly and evenly preheat the heating frame plate 21. The lead screw motor 111 drives the lead screw 110 to rotate, thereby driving the moving frame 12 to move along the base 11. When the moving frame 12 moves to the feeding port, the controller controls the hydraulic cylinder 14 to open. The hydraulic cylinder 14 drives the feeding plate 17 to move upward and open, and the moving frame 12 drives the bucket teeth of the excavator into the inside of the heating frame plate 21. Then the hydraulic cylinder 14 drives the feeding plate 17 to move downward and close.

[0027] After the moving frame 12 drives the bucket teeth of the excavator into the inside of the heating frame plate 21, the lead screw motor 111 stops working. The multiple heating plates 23 can make the temperature inside the heating frame plate 21 uniform; at the same time, local heating annealing can be carried out according to the parts of the bucket teeth of the excavator. By controlling the regulating motor 25 to turn on through the annealing controller 22, the regulating motor 25 drives the regulating lead screw 26 to rotate. The outer wall of the regulating lead screw 26 is threadedly engaged with the inner wall of the movable block 27. Therefore, when the regulating lead screw 26 rotates, it can drive the movable block 27 to move left and right along it. At the same time, the electric push rod 28 can drive the electric heating tube 29 and the local heating end 210 at the bottom to adjust the height up and down, so as to realize the position adjustment of the local heating end 210, so that this annealing equipment can carry out local heating annealing processing on the bucket teeth of the excavator according to the annealing temperature required by different parts of the bucket teeth of the excavator, which can greatly improve the control effect of the annealing processing of the bucket teeth of the excavator and improve the quality of the annealing processing of the bucket teeth of the excavator; at the same time, the multiple heating plates 23 cooperate with the local heating end 210 at the top, and can carry out heating annealing processing on the bucket teeth of the excavator, so that the annealing temperature distribution of the bucket teeth of the excavator is more uniform, effectively avoiding large thermal stress generated by the bucket teeth of the excavator due to uneven heating, keeping the heating temperature of the bucket teeth of the excavator in good uniformity, so that the bucket teeth of the excavator reach the required mechanical properties.

[0028] When the bucket teeth of the excavator are completed with heating annealing, the controller controls the hydraulic cylinder 15 to open. The hydraulic cylinder 15 drives the sealing plate 18 to move upward and open. The lead screw motor 111 continues to drive the lead screw 110 to rotate, and the moving frame 12 continues to drive the bucket teeth of the excavator to move into the cooling device 112 for cooling. After cooling, the controller controls the hydraulic cylinder 16 to open. The hydraulic cylinder 16 drives the discharge plate 19 to move upward and open, thus completing all the annealing processing of the bucket teeth of the excavator.
