Automatic cutting device for automobile trim skin and cutting method

Abstract

The invention discloses an automatic cutting device for automobile trim skin. The automatic cutting device comprises a cutting bed worktable, a cross beam, an air cylinder and a cutting machine head.The cross beam is fixed in a bestriding manner to the cutting bed worktable, and the cutting machine head is mounted on the cross beam; the cutting machine head comprises a tool bit frame, a tool bitelectric sharpening system and a cooling system. The tool bit frame comprises a TG transmission shaft, a fixed plate, a cutter and a cutterhead; the TG transmission shaft is connected to the power output end of the air cylinder, the top end of the cutter is fixed to the TG transmission shaft and the bottom end of the cutter penetrates the cutterhead; the tool bit electric sharpening system is rotatably mounted at the lower end of the machine head to polish the cutter; and the cooling system communicates to the cutterhead. According to the automatic cutting device disclosed by the invention, preparation and overstock of molds are avoided, input of accessories is reduced, and the cost is saved. According to the cutting method, the off-cut gap and the off-cut direction are optimized by meansof software, and based on digital processing, the cut products are diversified, thereby meeting the processing demands of conventional PVC and 3D composite material processing. The automatic cutting device achieves automatic production and improves the production efficiency.

Description

technical field [0001] The invention relates to the field of cutting beds, in particular to an automatic cutting device and a cutting method for automobile interior skin. Background technique [0002] In 1969, the first computer-controlled cutting machine came out in the United States. At first, the automatic cutting machine was mainly used in the garment industry. It was gradually introduced into the automobile industry in the 1990s. China also introduced automatic cutting equipment in the mid-1980s, mainly Lectra and Gerber. . [0003] The existing cutting device is manual punching, which requires manual typesetting, resulting in low coil utilization, and the project needs to re-make molds, resulting in a backlog of molds and increased costs. In addition, the mold of the manual punching device will be deformed after a long period of use, resulting in a decrease in product stability. Contents of the invention [0004] The technical problem mainly solved by the present i...
