Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, and in particular to a metal bending and cutting equipment. Background Technology

[0002] Modern precision springs are widely used metal stamping parts. They are formed through multi-station progressive dies, precisely calculating bending springback and other parameters during stamping. They possess excellent elasticity coefficients. Through mass production, each stamped spring is cut off immediately afterward, achieving continuous and uninterrupted processing using metal bending and cutting equipment, enabling large-scale production. However, existing metal bending and cutting equipment generally suffers from complex structures, which may lead to insufficient reliability of the processing equipment after long-term use.

[0003] For example, a metal bending and cutting device is disclosed in Chinese utility model patent with announcement number CN220312449U. Although the solution can use the displacement of the displacement frame to drive the bending plate to flip through the structural design of the sheet metal processing mechanism, thereby completing the bending processing of the metal sheet, effectively avoiding the input of a large number of components and simplifying the bending steps, it first uses a positioning hydraulic cylinder to push the positioning frame down to control the metal sheet, and then uses a cutting hydraulic cylinder to push the alloy cutter downward to cut. In addition, each time a transmission motor is needed to drive the bending plate to flip, the structure is too complicated. If it is used to process large batches of repeatedly stamped products such as metal springs, it will cause wear on the core structural components of the bending and cutting device. After long-term use, it may lead to a decline in the processing quality of precision springs.

[0004] In view of this, a metal bending and cutting device that can solve the above problems is proposed. Utility Model Content
