Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal workpiece processing, in particular to a simple tool used for sheet metal workpiece processing on a bending machine. Background Art

[0002] Various types of anisotropic stretching or forming are required when designing sheet metal workpieces. Traditional processes require the opening of general punching or digital punching dies, and the use of a bending machine to control the distance between the upper and lower parts and the downward pressure to process these dies. The bending machine can stop at any time during the descent of the upper die; Patent No. CN201921372936.1 has developed a simple tooling on a bending machine for sheet metal workpiece processing. The tooling of this technical solution can be directly processed and manufactured using the most commonly used steel plates in the factory according to the various shapes required for forming. There is no need to open a mold, which will reduce a lot of costs, and there is no time cycle for opening a mold, which can speed up process verification and proofing time. The molding effect is the same as opening a mold. After receiving a batch order, you can open a general punching or digital punching mold, which is suitable for different working conditions and brings better prospects for use.
