Uncoiling blanking forming method

Abstract

An uncoiling blanking forming method comprises the following steps that 1) steel coil uncoiling is carried out, namely a steel belt after steel coil uncoiling is subjected to washing and straightening and enters a blanking zone through a clamping conveying roller; 2) laser blanking is carried out, namely a steel coil enters the blanking zone, a laser blanking mode is used, a material piece with the needed shape is formed by cutting of a laser cutting head, and waste materials fall down and are output; 3) material piece output is carried out, namely the material piece is conveyed through a magnetism stretching conveying belt machine and then is carried to a stamping procedure through a mechanical arm or a robot; 4) stamping forming is carried out, namely the material piece is subjected to stamping and is machined into a workpiece; and 5) checking is carried out, namely the workpiece is checked and put in storage. The method can achieve series connecting of a blanking line and a stamping forming line, matching can be achieved, the middle links such as stacking, packing, conveying, locating, unpacking, conveying and position centering of piece materials and stamping forming workpieces and transferring sites are reduced, the technology processes are simplified and connected in series, and by laser blanking, coiling materials are directly machined into forming pieces.

Description

technical field [0001] The invention relates to the field of processing automobile sheets and coils, in particular to an uncoiling and blanking forming method for processing automobile sheets and coils into three-dimensional stamped sheets. Background technique [0002] A traditional auto sheet mold uncoiling blanking line has a production cycle of about 25 pieces per minute, and the annual output can reach 4-6 million pieces. After blanking the mold to obtain flat blank blanks, it needs to go through the stamping forming line to obtain stamped auto sheet parts . According to different investment and production scale, corresponding stamping and forming lines can be used to obtain three-dimensional parts. The beats of the commonly used robot stamping production lines in China are about 5 pieces per minute, and the beats of single-arm cross-bar manipulator stamping lines are about 10 pieces per minute. The beat of the stamping line of the material is slower, only 3-5 pieces p...

Problems solved by technology

[0005] In order to solve the huge mold costs, maintenance and maintenance costs caused by mold blanking, and to realize the flexibility of blanking methods, laser blanking has become an implementable method, but the beat of laser blanking to traditional mold blanking is still currently A technical bottleneck, even if multiple cutting heads are configured to
