Description

Technical Field

[0001] The utility model relates to the technical field of numerical control spring processing and production, in particular to a numerical control spring machine. Background Art

[0002] CNC spring machines are machines controlled by CNC technology and used to manufacture various types of springs. These machines are usually able to accurately cut, bend and form metal wire according to pre-set parameters and design drawings to produce spring products that meet specific specifications and requirements. The use of CNC spring machines can improve production efficiency, reduce labor costs, and ensure the production of high-quality spring products.

[0003] However, during the production process, since the spring is an uninterrupted production process, the manufactured springs will continue to extend outward until they reach the required size and parameters and are then cut off accordingly. However, during the production extension, the spring may be too long, which may cause the spring itself to shift, causing the subsequent spring production materials to be affected by the force and shift in position, and misalignment with the spring production operating parts, affecting the coordination between the materials and other operating parts, which in turn causes the manufacturing device to fail to work properly. It may also cause the produced springs to be subjected to force imbalance, causing the springs to deform or be damaged during the production process, resulting in twisting and breaking.
