& nbsp;& nbsp; Longitudinal cutting machine, also known as longitudinal cutting unit or longitudinal cutting line, is a necessary equipment for precision cutting of metal strips in the transformer, motor industry, and other industries. It cuts metal coils into strips of various widths required, and then harvests the strips into small rolls for use in the next process. It is mainly used for cutting materials such as tinplate, galvanized iron, silicon steel sheets, cold-rolled steel strips, stainless steel strips, aluminum strips, steel strips, etc.  & nbsp; & nbsp; There are many types of longitudinal cutting lines, which can be divided into thin plate longitudinal cutting lines and thick plate longitudinal cutting lines according to the thickness of the board that can be longitudinally cut;  & nbsp; & nbsp; According to the longitudinal cutting metal material, it can be divided into stainless steel longitudinal cutting wire, copper strip longitudinal cutting wire, cold plate longitudinal cutting wire, silicon steel longitudinal cutting wire, etc.  & nbsp; & nbsp; According to the degree of automation, it can be divided into fully automatic longitudinal cutting line and semi-automatic longitudinal cutting line.  & nbsp; & nbsp; In the pipe making machine, customers need to use longitudinal cutting lines to obtain the size they need, and then produce the pipe material of the required size through the pipe forming machine.  & nbsp; & nbsp; The main process of longitudinal cutting line is: coil storage → winding → unwinding → guide head → clamping and rough straightening → cutting head → waste collection → loop → centering → longitudinal cutting → waste edge winding → loop → separation and tension → slitting → separation and winding → unloading  & nbsp; The slitting machine is suitable for longitudinal cutting of metal strip materials and rewinding the cut narrow strips into rolls. It has the characteristics of easy operation, high cutting quality, high material utilization rate, and stepless cutting speed regulation. The main structure consists of unwinding, feeding positioning, slitting, and coiling.  & nbsp; & nbsp; Scope of application: Cold rolled steel coils, stainless steel, color coated coils, and tinplate longitudinal cutting production lines. Roll thickness 0.3-3mm, roll width 1850mm, longitudinal cutting width 30mm;  & nbsp; Technical features: The longitudinal cutting machine is mainly used for tension-free cutting of strip materials, with the characteristics of precise cutting and less edge burrs. There are feeding trolley, unwinding machine, clamping machine, guide device I, disc shearing device, guide device II, loop device, tension generating device, winding device, feeding trolley, waste edge winding device, hydraulic control device, electrical control device, etc& nbsp;
