Uncoiling and blanking method

Abstract

Provided is an uncoiling and blanking method. A strip coil is uncoiled, straightened and subjected to head cutting and enters a movable sleeve. After the strip coil leaves the movable sleeve, the surface of the strip coil is washed and smoothened, and the strip coil is subjected to laser cutting and blanking. Laser cutting adopts static double laser cutting heads to cut the strip coil, cut waste materials fall in a cutting area and are conveyed to the outside. After cutting is finished, obtained sheet materials are cut off for the last time and received by a material receiving device and conveyed to a grabbing stacking area through a conveyor belt, and the sheet materials are stacked. By means of the uncoiling and blanking method, laser static cutting is adopted, operation rhythm and yield can be effectively improved through collaborative operation of the two laser cutting heads, a die blanking mode is replaced, dies are not required, maintaining cost of the dies is saved, die stacking space is not required, an operation mode is flexible, production line layout is simplified, and operation is easy.

Description

Technical field [0001] The invention relates to the field of automotive sheet coil processing, in particular to an uncoiling blanking method. Background technique [0002] Nowadays, facing the various limitations of traditional mold blanking lines, steel processing centers and vehicle manufacturers urgently need a flexible blanking production line to reduce the cost of mold design, processing, maintenance and maintenance. R&D and processing time such as mold development and trial cycle, and at the same time, respond to the market's increasing demand for new models and small-volume individual models. [0003] Chinese patent CN102105256 uses at least two movable portal frames and at least one movable laser cutting head for each portal frame to move horizontally or longitudinally. During the cutting process, the strip moves and the cutting head follows the strip for dynamic cutting. Can obtain production output close to the traditional blanking line. However, it is difficult to ensu...

Problems solved by technology

The processing head between the two belt-type transmission mechanisms inevitably produces indirect cutting contact with the belt in the cutting area, so that the detection and replacement of the transmission belt affects the continuous production of the system. At the same time, there is a small area of ​​waste falling in the cutting area. possibility of falling

[0005] The patent is based on the improvement of material utilization rate by laser cutting, strong adaptability to plate thickness and plate width, and the advantages of greatly simplifying the production line without special molds. However, according to the requirements of high speed and high output of the production line, and reliable There is a certain conflict between high cutting quality and smooth waste removal, which is still the technical difficulty of high-speed laser cutting for material processing.
