Stepping-type laser cutting uncoiling blanking line

Abstract

The invention belongs to the technical field of plate coil material machining, and discloses a stepping-type laser cutting uncoiling blanking line. The stepping-type laser cutting uncoiling blanking line comprises an uncoiling machine, a leveling machine, a fixed-length feeding machine and a laser cutting machine which are sequentially connected in series. A coil material is placed on the uncoiling machine; a special cutting platform is arranged on the laser cutting machine; the laser cutting machine comprises three or more laser cutting heads arranged above the special cutting platform; and ablanking opening is formed in the position, corresponding to cut waste, of the special cutting platform. According to the stepping-type laser cutting uncoiling blanking line, the laser cutting machine is adopted to replace a traditional mechanical press machine, continuous production of laser cutting is achieved, a blanking die is not needed, the layout of parts is unrestricted, arbitrary optimizing can be conducted, the shapes of the parts are unrestricted, the shapes which are hard to machine by a traditional uncoiling blanking line can be machined, and the material utilization rate can beincreased to the largest limit.

Description

technical field [0001] The invention belongs to the technical field of plate and coil processing, and in particular relates to a step-by-step laser cutting uncoiling and blanking line. Background technique [0002] The uncoiling blanking line is a complete set of technical equipment widely used in the automobile industry at present. The uncoiling blanking line is used to unwind, level, and blank (puncher) the coil material into a sheet through a mold, and then automatically stack and pack it. It is distributed to the stamping line of the whole vehicle factory to stamp the parts required for the car body; its most notable feature is to obtain irregularly shaped sheets through die blanking (punching). Therefore, in the production process of the uncoiling blanking line , a pair of molds usually only corresponds to one part; it means that if the OEM eliminates a certain model, the blanking mold corresponding to this model is basically in a scrapped state (only for after-sales se...

Problems solved by technology

[0003] Since the advent of the first laser, laser cutting technology using laser as a tool has developed rapidly; high-speed, high-precision laser cutting machines are more and more widely used in sheet metal cutting, which can cut arbitrary shapes, laser cutting It can replace traditional mold blanking (blanking); in the development process of new models, the blanks for the stamping and trial production of parts in the early stage come from laser cutting, but the existing laser cutting production process mode is completely unable to adapt to large-scale automotive stamping parts. material supply
