Description

technical field [0001] The invention relates to an integrated stretching, shearing and bending machine for metal wire and its processing technology. It belongs to the technical field of all-in-one equipment. Background technique [0002] In the assembly process of some tools, it is usually necessary to stretch and straighten the metal wire before use. The straightened metal wire must have certain physical and mechanical properties. However, the existing wire straightening device has low production efficiency for wire straightening. The labor intensity is high, and the size uniformity of the wire material cannot be guaranteed due to uneven force and easy slipping during the straightening process, thereby affecting the quality of the wire material. For some parts processed by metal wire, for mass production, when making metal wire, usually a longer wire is processed first, and then the long wire is cut into sections by wire cutting equipment Short wires of equal length. The...

Problems solved by technology

This manual method of producing brackets is not only inefficient, but also difficult to agree on parameters such as bending points and bending solid angles, and the symmetry and balance cannot meet the design requirements, which directly affects the assembly quality of the finished product

[0005] In summary, in order to solve the problems in the prior art that the size uniformity of the wire material cannot be guaranteed due to uneven force and easy slipping during the straightening process, and the shearing equipment is immature, the manual bending method is used to produce bent metal wire, the efficiency is low, the parameters such as the bending point and the bending solid angle are difficult to be consistent, and the symmetry and balance cannot meet the design requirements, which directly affects the assembly quality of the finished product. Stretching and bending are integrated to realize full automation integration, realize straightening first and then shear bending, and realize the straightening of metal wire through the combination of stretching deformation and plastic deformation, and the wire straightening efficiency is high , in the process of stretching and straightening, it has anti-slip properties, simple structure, and a stretching, shearing and bending machine and its processing technology for assembling metal wires with uniform shape
