1.Scope of Application
Cold sawing machine is a kind of cutting equipment widely used in the production line of section steel in metallurgical plants, especially in the rolling production line of profile steel. It is generally installed on the finishing line of section steel workshop behind the rolling mill. Its main function is to cut the head, tail and length of the profile after cooling and straightening in the cooling bed. Compared with other cutting equipment, the cold saw has the advantages of simple equipment, light weight and high production efficiency.
2.Specification
Blade Diameter Φ 1100㎜～ Φ 1800㎜
3.Product Introduction
The classification of cold saws is similar to that of hot saws. In terms of structure, cold saws can be divided into sliding seat type and four-bar type; According to its layout in the operation line, it can be divided into fixed sawing machine and mobile sawing machine; According to the main transmission form, it can be divided into motor direct transmission type and belt indirect transmission type; It can be divided into three types according to the transverse movement: fixed type, sliding plate type and roller type; It can be divided into four link type and rack type according to the form of feeding saw.
The diameter of circular sawing machine designed and developed by NHI Co., Ltd Φ 1100㎜～ Φ 1800㎜。 The mobile cold saw blade is driven by an AC motor and a pair of spiral bevel gears. The saw blade adopts hydraulic feed. The feed speed of the saw blade can be adjusted according to the different sawing section and sawing force. The clamping of profiles on the roller table is also completed by the hydraulic device installed on the saw machine. The whole sawing process can be controlled by PLC program. The cold sawing machine has a reasonable structure, adopts rolling friction and hydraulic feeding, and works stably and reliably.
