Technical Field

[0001] The present invention relates to the technical field of aluminum profile straightening, and in particular to an aluminum profile straightening method and an intelligent heat treatment production line. Background Art

[0002] Aluminum products are made of aluminum and other alloy elements. The main metal element is aluminum, plus some alloy elements to improve the performance of aluminum products. Straightening is a method of changing a bent object into a straight line by external force, which is mostly used in the smelting industry. For example, items such as iron wires are usually transported in a circular shape for convenience of transportation, and external force is required for straightening when in use. However, the existing aluminum profile straightening machines do not have a heating function during use and cannot preheat the aluminum profiles to be straightened, resulting in the aluminum profiles being prone to springback after straightening, affecting the straightening effect, and thus bringing inconvenience to the processing of aluminum profiles. Therefore, it is of great practical value to have an aluminum profile straightening machine with a heating function.

[0003] The patent with the patent number 202021677909.8 discloses an aluminum profile straightening machine with a preheating function, which realizes the preheating of aluminum profiles by setting a hot air blower above the clamping block, thereby reducing the straightening energy consumption and providing the straightening effect; the patent with the patent number... realizes the preheating of aluminum profiles by setting a heating component in the mounting hole at the bottom of the fixed frame, thereby reducing the straightening energy consumption and providing the straightening effect.

[0004] However, the above patents cannot meet uniform heating, the straightening effect is poor, and they cannot quickly perform automatic outloading and batch straightening of aluminum profiles by the roller bracket and the conveyor belt, resulting in low efficiency and lack of intelligence.

[0005] Therefore, it is necessary to propose an aluminum profile straightening method and an intelligent heat treatment production line to solve the problems that the traditional aluminum profile straightening machine cannot meet uniform heating, has a poor straightening effect, cannot quickly perform automatic outloading and batch straightening of aluminum profiles by the roller bracket and the conveyor belt, has low efficiency, and lacks intelligence.

[0022] Figure 4 It is a step diagram of the aluminum profile straightening method of the present invention. Detailed implementation manners

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific drawings.

[0024] See Figure 4 , an aluminum profile straightening method, characterized by including the following steps: a. Place the aluminum profile on the rollers 62 of the roller bracket 6 in the bottom shell 4, clamp one end of the aluminum profile with the fixed clamp 2, and clamp the other end of the aluminum profile with the moving clamp 3; b. The second lifting device 52 lowers the top cover 5 until the top cover 5 and the bottom shell 4 are closed to form a heating chamber 100; c. The control device controls the first lifting device 61 to drive the roller bracket 6 to lift and lower, and controls the moving clamp 3 to move to straighten the aluminum profile. The roller 62 corresponding to the position of the moving clamp 3 is at the lowest position, and the remaining rollers 62 are at the highest position; d. The control device controls the first hot air blower 63 in the roller bracket 6 and the second hot air blower 51 in the top cover 5 to blow hot air for heating; e. After the straightening work is completed, the control device controls the second lifting device 52 to raise the top cover 5; f. The control device controls the first lifting device 61 to drive the roller bracket 6 to lower. When the roller bracket 6 reaches the lowest position, the top of the roller 62 is lower than the top of the conveyor belt 7 and higher than the bottom surface of the bottom shell 4; g. The control device controls the conveyor belt 7 to transport the straightened aluminum profile away from the bottom shell.

[0025] In this way, the aluminum profile can be evenly heated by hot air both above and below. The load of the moving clamp 3 is relatively low, and the straightening effect is good. Moreover, its lifting top cover 5 and the bottom shell 4 that allows the roller bracket 6 and the conveyor belt 7 to move can cooperate with the roller bracket 6 and the conveyor belt 7 to quickly carry out the automatic delivery and batch straightening of the aluminum profile, with high efficiency and great intelligence.

[0026] The outlet air temperature of the first hot air blower 63 is lower than that of the second hot air blower 51. Since the first hot air blower 63 is closer to the aluminum profile than the second hot air blower 51, the fact that the outlet air temperature of the first hot air blower 63 is lower than that of the second hot air blower 51 can ensure more uniform heating.

[0027] In the step d, the control device starts the corresponding range of the first hot air blower 63 and the second hot air blower 51 according to the movement of the moving clamp 3. This is more energy-saving and avoids unnecessary waste.

[0028] In the step e, before the top cover 5 rises, the control device controls the first hot air blower 63 and the second hot air blower 51 to stop heating and blowing. This is more energy-saving and can cool the aluminum profile, making the delivery faster, safer, and improving the batch straightening efficiency of the clamping blocks.

[0029] In the step e, before the top cover 5 rises, the control device controls the first hot air blower 63 and the second hot air blower 51 to stop heating. This can further save energy and can cool the aluminum profile, making the delivery faster, safer, and improving the batch straightening efficiency of the clamping blocks.

[0030] In the step e, when the temperature in the heating chamber 100 is lower than the preset safety temperature, the control device controls the second lifting device 52 to raise the top cover 5. This can further ensure the cooling of the aluminum profile, making the delivery faster, safer, and improving the batch straightening efficiency of the clamping blocks.

[0031] The control device controls the outlet air temperatures of the first hot air blower 63 and the second hot air blower 51 according to the required temperature. This can select the corresponding temperature according to the need and improve the straightening effect of the aluminum profile.

[0032] When the load of the moving clamp 3 is lower than the preset value, the control device controls the first hot air blower 63 and the second hot air blower 51 to cool down or stop heating. This avoids overheating of the aluminum profile and affects the straightening effect.

The driving mechanism 72 drives the driving wheel 71 to rotate, and the driving wheel 71 drives the conveyor belt 7 to rotate in a direction perpendicular to the moving direction of the moving clamp 3. There are several conveyor belts 7, and each conveyor belt 7 is inserted between two adjacent roller brackets 6. The range of the top cover 5 covers all the roller brackets 6. A plurality of second hot air blowers 51 are arranged in the top cover 5 and distributed along the moving direction of the mobile clamp. The air outlets of the second hot air blowers 51 face downward. The top cover 5 is lifted up and down by a second lifting device 52. When the top cover 5 is lowered, the top cover 5 and the bottom shell 4 form a heating chamber 100 that allows the mobile clamp to move. A temperature sensor 9 is arranged in the heating chamber 100.
