（5） Programmable Control Center (PLC)

The programmable control center is a key component of the straightening machine. The complex and orderly actions of the straightening machine are all completed under its program control. The PLC and accounting machine processing system communicate with each other and coordinate to control the orderly clamping, measurement, selection of straightening parts, pressurization and correction of various performance components. The system adopts the OMRON series programmable controllers from Japan (or products from companies such as MITSUBISHI from Japan and SIEMENS from Germany can be selected according to user requirements), and electrical operation and performance components mainly use products from companies such as MITSUBISHI, FUJI, OMRON, MATSUSHITA, and SCHNEIDER from France, ensuring stable and reliable operation.

（6） Accounting machine processing system

The calculation and processing system of the straightening machine is composed of an ultra high precision data acquisition system, a secure and reliable input and output system, an industrial integrated operation station with a large screen color LCD display, a highly professional software package, a fully Chinese human-computer interaction interface, rich and colorful graphic and text display, and printable data calculation and output.

In terms of software planning, we have incorporated our unique straightening concept by drawing on the advanced experience of various professional manufacturers abroad, and the point vibration correction has greatly accelerated the straightening speed. Vector differentiation correction is specifically developed and planned for workpieces with D-shaped cross-sections or quenched outer surfaces (such as steering gear racks). This type of workpiece usually has differences in mechanical characteristics in different directions due to its irregular shape or uneven heat treatment in various directions. If traditional proofreading methods are used, it is difficult to meet the technical requirements of the product. Vector differentiation correction can establish different correction models in different directions for correction, effectively solving the problem of difficult alignment of such workpieces.

In terms of software completion, we chose C++BUILDER 6.0 programming. The performance of C language application in industrial control has made our software package perform well in terms of code execution speed and stability. The fully Chinese human-computer interaction interface is more in line with the usage habits of Chinese people, making it easier for operators to understand and grasp. A detailed online electronic graphic and text help system can help beginners quickly grasp the essentials of operation. The storage of workpiece parameters that can be freely expanded satisfies the requirement of one machine for multiple uses. A comprehensive self diagnosis system for faults can enable operators to quickly identify equipment faults. The measurement of dynamic waveform display can intuitively detect surface defects such as roundness errors, burrs, pits, etc. of the workpiece. What is valuable is that we have the ability to redevelop the entire system and a skilled team, and even the ability to plan specifically for special workpieces and reasonable requirements from users, achieving interaction with users in terms of skills, in order to effectively utilize the equipment's functions and power.
