Description

Technical Field

[0001] This utility model relates to the field of aluminum coil processing technology, and in particular to a precision leveling device for aluminum coils. Background Technology

[0002] Precision leveling (straightening) of aluminum coils is a key process in aluminum sheet and strip processing, and is widely used in fields such as automobiles, aerospace, electronics, and packaging where the flatness, surface quality, and dimensional accuracy of the sheet material are extremely important.

[0003] In traditional aluminum coil leveling equipment, intense friction occurs between the flattening roller (straightening roller) and the aluminum sheet / strip during high-speed, continuous leveling. Simultaneously, the plastic deformation of the sheet itself releases a significant amount of heat. This frictional and deformation heat causes a substantial increase in the temperature of the flattening roller, resulting in thermal expansion. This thermal expansion is one of the core challenges restricting the performance stability and processing accuracy of precision leveling equipment. Its main problems include: deterioration of roller shape accuracy; uneven heat dissipation or inconsistent temperature rise in different parts of the roller body leading to uncontrollable changes in roller shape (such as crown), deviating from the preset ideal working curve, directly affecting the straightening effect; decreased roller gap stability; and increased roller diameter due to thermal expansion, altering the preset roller gap (gap) crucial to straightening accuracy, disrupting the stable application of straightening force, and limiting production continuity. To avoid excessive temperature rise leading to loss of accuracy control and equipment damage, traditional equipment is often forced to reduce production speed or frequently stop for cooling, severely impacting the efficiency and continuity of high-precision sheet metal production.

[0004] To address this, a precision leveling device for aluminum coils was proposed. Utility Model Content

[0023] Example 1

[0024] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a precision leveling device for aluminum coils, including a base plate 1, a flattening assembly 2, a cooling assembly 3, and a cutting assembly 4.

Rubber sleeves 27 are fixedly connected to the outside of both the first flattening roller 22 and the second flattening roller 26.

[0025] The cooling assembly 3 includes cooling channels 31, which are respectively opened inside the first flattening roller 22 and the second flattening roller 26. A through groove 32 is provided in the middle of both sides of the first flattening roller 22 and the second flattening roller 26. A connecting pipe 33 is provided in the middle of both sides of the first flattening roller 22 and the second flattening roller 26.

The through grooves 32 communicate with the cooling channels 31 and the connecting pipes 33. A second mounting plate 34 is fixedly connected to the outer wall of one side of the front end of the base plate 1. A liquid suction pump 35 is provided at the front end of the upper surface of the second mounting plate 34, and a liquid storage tank 36 is provided at the rear end of the upper surface of the second mounting plate 34. A first hose 37 is fixedly connected to the suction end of the liquid suction pump 35. The side of the first hose 37 near the center of the base plate 1 is fixedly connected to a connecting pipe 33. The side of the connecting pipe 33 away from the liquid suction pump 35 is fixedly connected to a second hose 38.

[0026] Furthermore, through the cooling channels 31 inside the first flattening roller 22 and the second flattening roller 26, and through the cooling fluid circulation system composed of the suction pump 35, the first hose 37 and the second hose 38, continuous and effective cooling fluid circulation is achieved.

[0027] Example 2

[0028] Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0029] The cutting assembly 4 includes a second connecting frame 41, which is disposed on the upper surface of the base plate 1 near the front end. A first cutting blade 42 is fixedly connected to the middle of the inner wall of the second connecting frame 41.

A second connecting plate 44 is fixedly connected to the output end of the second electric telescopic rod 43. A second cutting blade 45 is fixedly connected to the middle of the lower surface of the second connecting plate 44. A third mounting plate 5 is disposed on both sides of the front and rear ends of the second connecting frame 41. The lower ends of the third mounting plates 5 are fixedly connected to the base plate 1. A rotating roller 6 is rotatably connected between the upper ends of the third mounting plates 5. A third connecting plate 7 is fixedly connected to both sides of the rear end of the upper surface of the base plate 1.

The first electric telescopic rod 24, the liquid suction pump 35, the temperature sensor 310, and the second electric telescopic rod 43 are all electrically connected to the control panel 9.

[0030] Furthermore, the designed second electric telescopic rod 43 drives the second connecting plate 44, which is closely connected to it, to perform orderly telescopic movements. The second cutting blade 45 and the first cutting blade 42 form a perfect cooperation, thereby achieving efficient and precise cutting of aluminum coil materials. At the same time, the rotating roller 6 can play a good guiding and lubricating role in its conveying process, which greatly improves the smoothness of the aluminum coil in the conveying process and ensures the efficiency and stability of the entire cutting operation.

[0031] The remaining structure is the same as that in Example 1.

[0032] The specific operating principle of this utility model is as follows:

[0033] The aluminum coil is flattened by placing it on the uncoiling shaft 8, passing the coil head between the first flattening roller 22 and the second flattening roller 26, and then by driving the first connecting frame 25 via the first electric telescopic rod 24.

[0034] During the flattening process, the temperature sensor 310 can detect the external temperature of the first flattening roller 22 in real time. When the temperature reaches the set threshold, the coolant inside the storage tank 36 is drawn into the cooling channel 31 through the first hose 37 by the suction pump 35. Then, it is circulated back into the storage tank 36 through the connecting pipe 33 and the second hose 38, thus forming a coolant circulation system for continuous and effective coolant circulation. This effectively suppresses the temperature rise and expansion phenomenon caused by frictional heat and deformation heat during the operation of the first flattening roller 22 and the second flattening roller 26. This measure not only ensures that the roller shape accuracy of the flattening roller remains constant, but also further ensures the speed stability of straightening and the high consistency of the flatness of the plate throughout the flattening process. In addition, it significantly improves the overall stability and operating accuracy of the equipment, avoids a series of problems such as roller gap changes and plate surface quality fluctuations caused by roller temperature rise, and ensures an industrial environment for long-term continuous high-precision production.

[0035] At the same time, the rotating roller 6 can play a good guiding and lubricating role in its conveying process, which greatly improves the smoothness of the aluminum coil in the conveying process and ensures the efficiency and stability of the entire cutting operation.

[0036] When cutting is required, the second electric telescopic rod 43 drives the second connecting plate 44, which is closely connected to it, to perform orderly telescopic movements. The second cutting blade 45 and the first cutting blade 42 form a perfect cooperation, thereby achieving efficient and precise cutting of aluminum coil materials.

[0037] The temperature sensor 310 in this utility model is existing technology, so it will not be described in detail.
