& nbsp; Kaiping machine, also known as unwinding leveling machine or unwinding leveling production line, is divided into three types in the metal processing industry, namely:1. Open book leveling and horizontal cutting production line2. Open book leveling and longitudinal cutting production line3. Open book leveling, longitudinal cutting, winding, fixed length, transverse cutting, composite line  & nbsp; The cross cutting machine is used to unwind, level, cut metal coils into flat sheets of the required length, and stack them. Suitable for processing cold-rolled and hot-rolled carbon steel, silicon steel, tinplate, stainless steel, and various metal materials after surface coating. The standard configuration consists of: feeding trolley, unwinding machine, feeding machine, feeding pre calibration machine, transition worktable, limit device (trimming machine, edge wire winding machine), leveling host, sizing device, tail plate feeding machine, shearing machine, conveying worktable, throwing machine, coding worktable, finishing device, hydraulic system, and electrical control system. The hydraulic system of this production line mainly uses high-precision components from Taiwan, and the electrical control adopts imported PLC program controllers and touch screens for full line function control. The leveling main motor adopts a DC motor, and the DC controller adopts products from the British Continental company. It has the characteristics of high automation, high cutting accuracy, stable and reliable performance, and easy operation and maintenance.  & nbsp; According to the different types of metal sheets, common ones include stainless steel slitting machine, steel plate slitting machine, aluminum plate slitting machine, and copper plate slitting machine. The technical parameters to be noted for the horizontal cutting and slitting processing length of the Kaiping machine are as follows:1. Processing thickness: According to customer requirements, the thickness requirements for metal stainless steel plates are also different. Therefore, each leveling machine has upper and lower limits for processing thickness. Exceeding these limits can cause poor shear and even damage to the cutting tools2. Processing weight: Depending on the weight of the customer's coil, the importance of the unwinding machine's load-bearing capacity varies. Therefore, there is generally an upper limit for the unwinding machine. If the steel coil is overweight, the feeding trolley cannot operate and may even cause damage to the oil cylinder;3. Processing width: The width of the coil material varies according to customer requirements and generally has upper and lower limits. If it exceeds the upper limit, it cannot be rolled up, and if it exceeds the lower limit, it cannot be aligned;4. Processing length: The length requirements for processed coil materials are also limited, generally with upper and lower limits. If exceeded, the material cannot be stamped;5. Processing speed: There are also certain requirements for the speed between the various hosts of the entire horizontal cutting line. The speed of threading, uniform speed, and variable speed mainly affect the processing efficiency.
