Cutting-off Mechanism Mould for Cold Heading Machine

Cold heading machine scissors‌ are an important part of the cold heading machine, mainly used for shearing and forming metal materials. Cold heading machine is a kind of equipment specially used for batch production of fasteners such as nuts and bolts. Its basic principle is to press and deform the metal material through the pressure of the mold to achieve the purpose of processing and forming.‌
The design and manufacture of cold heading machine scissors require high precision and durability to ensure the accuracy of shearing and forming.

The Requirements for Cold Heading Machine Cutting Knife Mainly Include Gap Adjustment and Material Selection and Maintenance.


Gap Adjustment

The gap size of the cold heading machine scissors has an important impact on the processing quality and equipment life. The ideal gap range should be controlled between 0.02-0.05mm, which can ensure the dimensional accuracy of the nut, avoid burrs on the cut or extrusion deformation of the blank, and thus ensure the quality of the parts. In order to maintain the consistency of the gap size, regular inspections and timely adjustments are required. The specific process should be operated according to the model and instructions of the nut cold heading machine to ensure the accuracy and safety of the adjustment.


Material Selection

Cold heading machines usually use high-quality metal materials with good "plastic deformation", such as rivet screw steel. These materials need to meet strict chemical composition and mechanical property standards to ensure the surface quality and dimensional accuracy of the finished product.


Accuracy

The most crucial factor ensuring the durability and service life of a mold is precision. And every one of our

The split mold achieves a very high added value and long service life through high-precision machining at 1/1000mm.

At the same time, it saves time for replacing damaged molds, contributing to the reduction of production costs.
