摘要： The present invention provides a cell phone frame and a method for manufacturing the same, and relates to the technical field of cell phone accessories. The cell phone frame includes a composite plate, the composite plate encloses a receiving space for receiving a cell phone, the composite plate includes a first plate and a second plate, a first side surface of the first plate is provided with striations, the first side surface of the second plate and the first side surface of the first plate are connected by rolling, and the striations which have a pitch of 0.005 mm to 0.03 mm between adjacent striations account for more than 90% of all the striations. According to the cell phone frame provided in the embodiment of the present invention, the first side surface of the first plate is roughened to form striations, which increases the area of the first plate and the second plate subjected to rolling, so that a composite plate produced by combining the first plate and the second plate has a higher bonding strength, thereby ensuring that the cell phone frame is firmer.

摘要： The present invention provides a composite plate, a composite plate roughening device, and a method for manufacturing a composite plate, and relates to the technical field of metal plate materials. The composite plate includes a first plate and a second plate, wherein a first side surface of the first plate is provided with striations, the first side surface of the second plate and the first side surface of the first plate are connected by rolling, and the striations which have a pitch of 0.005 mm to 0.03 mm between adjacent striations account for more than 90% of all the striations. For the composite plate described in the embodiments of the present invention, the first side surface of the first plate is roughened such that the first side surface of the first plate and/or the first side surface of the second plate is configured with striations, which increases an area of the first plate and the second plate subjected to rolling, whereby the composite plate produced by combining the first plate and the second plate has a higher bonding strength and thus a stronger bonding.

摘要： The present invention relates to the technical field of material processing and provides a method for making a metal material composite, including: contacting a first surface of a first plate with a second surface of a second plate; placing the first plate and the second plate in a recess in a circumferential direction of a first roller such that a third surface of the second plate contacts a bottom wall of the recess in a circumferential, the third surface being opposite the second surface, the first plate having a greater hardness than the second plate; and controlling a first roller and a second roller to rotate, thereby connecting by rolling the first plate and the second plate into a composite plate, where a fourth surface of the first plate contacts a surface of the second roller and the fourth surface is opposite the first surface during the rolling. According to the method for making a metal material composite in the present invention, flashings and burr on the side edges of a composite plate are avoided by placing the first plate and the second plate in a recess for machining.
