Description

Technical Field

[0001] The invention belongs to the technical field of aluminum profile processing equipment, and particularly relates to a bending mechanism for aluminum plate fan-shaped arc strip forming processing, and more particularly to a bending method for aluminum plate fan-shaped arc strip forming processing. Background Art

[0002] During the processing and manufacturing of aluminum profiles, aluminum material extrusion operations are required to obtain aluminum profiles of preset shapes.

[0003] Arc-shaped fan-shaped aluminum profiles are usually used as anti-collision strips for objects. Aluminum profiles are formed by heating and extruding aluminum rods. The arc strips of the extruded aluminum profiles will be guided and conveyed by conveyor rollers. When the conveyor rollers start to rotate, static friction occurs due to the mismatch between the moving speed of the extruded aluminum profile and the speed of the conveyor rollers. Linear or strip patterns perpendicular to the extrusion direction are formed on the surface of the aluminum profile, affecting the appearance of the aluminum profile and causing an increase in the defective rate.

[0004] Therefore, the existing aluminum profiles are prone to surface patterns during extrusion and transmission, which cannot meet the needs of actual use. Therefore, there is an urgent need for improved technology in the market to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a bending mechanism and method for fan-shaped arc strip forming processing of an aluminum plate. The moving height of a loading assembly is monitored by a sensor. When the loading assembly moves to a set height, the position signal of the loading assembly is fed back to an external controller. The external controller receives the signal data fed back from the sensor, controls the start of a first motor, and drives a conveying device to transport the aluminum profile to be bent to a subsequent processing station, so that the aluminum profile moves to the top of a conveying roller and then the conveying device is started. This can avoid affecting the aesthetics of the aluminum profile due to the inconsistency between the moving speed of the aluminum profile extrusion and the speed of the conveying roller, and solves the problem that the existing aluminum profile is prone to patterns on the surface during extrusion and transmission.

The receiving mechanism includes a driving unit for feeding, an adjusting unit for adjusting the receiving height and a loading assembly. The receiving mechanism is connected to the extruder 1, and the loading assembly is connected to the adjusting unit. During use, by adjusting the adjusting unit, The degree of adaptation between the material loading component and the aluminum alloy profile is controlled. The advantage of such a setting is that the height difference between the material loading component and aluminum profiles of different specifications can be reduced. A U-shaped block 8 is fixedly installed on the inner wall of one side of the conveying device 2. A sensor 9 is fixedly installed on one side of the U-shaped block 8. The sensor 9 is electrically connected to the first motor 3. The moving height of the material loading component is monitored by the sensor 9.

[0038] Among them Figure 5 and Figure 6 As shown, the guide assembly includes a pair of first guide rails 7 fixedly mounted on the side wall of the conveying device 2, a moving sleeve 24 is slidably mounted on the first guide rail 7, a pair of slide grooves are provided on the first guide rail 7, the moving sleeve 24 is adapted to the slide grooves, a second guide rail 18 is fixedly mounted on the top of the moving sleeve 24, a slider 23 is slidably mounted in the second guide rail 18, and the central position of the moving sleeve 24 is formed into an inner concave M-shaped structure by bending.
