What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

Used for intelligent fault-tolerant semi-physical simulation experiment of engine control system

 

Construction and debugging of semi-physical closed-loop control system. This paper first established a component-level real-time model of a certain type of turboshaft engine, and then used this real-time model to form a closed-loop system on a mechanical hydraulic fuel regulation system. This experiment was carried out on the turboshaft engine semi-physical simulation experiment platform of 608 Institute. The experimental device is shown in Figure 2. The engine digital simulator is equipped with a real-time component-level model of a turboshaft engine. According to the position of the load rod (given by the potentiometer outside the experimental device) and the fuel flow rate Gfu, the gas generator speed N and power turbine speed are calculated from the model. N. The static pressure P and N at the outlet of the compressor are sent to the control cabinet through the AD channel output speed signal to drive the motor 1 and the motor 2 respectively; and the output pressure P electrical signal is converted into a pressure signal through electrical conversion, and the pressure signal after passing through the voltage divider The pressure is P′ and is sent to the fuel control system. The automatic fuel controller controls the N speed to maintain a constant speed by reflecting the fuel-air ratio G’. Since the numerical control system of the turboshaft engine is still under development, this experiment uses a hydraulic-mechanical fuel control system instead.

This article first conducted an open-loop acceleration and deceleration test. After a preliminary assessment of the system’s work, the closed loop can be cut into the closed loop only by making the fuel flow at the starting point approximately the same. During the closed-loop experiment, the strong fuel oscillation was caused when the load rod was pushed, so that the system could not work normally. After analyzing the experimental results, the following methods were adopted: (1) Increase the resistance of the fuel regulator: semi-physical simulation research on the intelligent fault tolerance technology of the engine numerical control system, reduce the magnification; (2) increase the interrupt timing program, and Simplify the real-time graphical interface, all curves and digital quantities are displayed in the simplest way, and the interface is convenient and friendly. *The problem of fuel oscillation has been solved afterwards. It should be noted that the same oscillation phenomenon occurred during the bench test of this system together with the engine, which was also solved by increasing the damping and reducing the magnification. The results of the semi-physical simulation experiment of the engine control system show that the results of the semi-physical simulation experiment are consistent with the bench test phenomenon of the turboshaft engine. The system can be used in the intelligent fault-tolerant semi-physical simulation experiment of the engine control system.
