Description

Technical Field

[0001] The invention belongs to the technical field of carbon fiber composite material processing, and in particular relates to a carbon fiber composite plate grooving and edge trimming device. Background Art

[0002] Carbon fiber composite materials have become a commonly used lightweight and high-strength material in model airplanes and aircraft manufacturing due to their advantages of light weight and high strength, and will also be gradually widely used in the automotive field. In the process of model airplanes and aircraft manufacturing, the bonding of carbon fiber composite materials is an extremely common and critical connection process. Whether it is the processing of raw materials or the bonding process, the requirements are very strict. In the bonding process of carbon fiber composite sheets, it is necessary to grind the edges or groove the edges to increase the contact area of ​​the bonding surface. However, due to the hardness of the composite material, the use of traditional grinding wheel chamfering is not only difficult to form, but also easy to cause carbon fiber composite materials to burn, reducing the quality of raw material processing. In addition, the grinding wheel cannot groove the edges. Although traditional metal CNC machining machine tools can meet the action requirements, the speed is relatively low, and they cannot cut carbon fiber plates or clamp large areas of plates. Based on this, it is particularly necessary to design a device that can not only chamfer, but also groove the edges of thick composite plates, and fully avoid the situation of carbon fiber composite materials burning.
