To reduce the development cost of bending machine molds, one key aspect is to pay attention to mold design, as it is a very important factor in determining development cost and timeline. Therefore, many manufacturers invest heavily in the design of bending machine molds. The design of bending machine molds primarily includes material selection, product structure, and synchronous engineering applications.
With the rapid development of society, China's manufacturing industry is also advancing at a high pace. Bending machine molds are one of the important equipment in the manufacturing sector. The competitiveness of the industry is increasingly intense. Therefore, for both the overall industry and bending machine mold manufacturers, reducing the development costs of bending machine molds is a concerning and critical issue in the field of bending molds.
Selection of Material for Chinese Bending Machine Molds: Generally, T8 or T10 and better 42CrMo are used. The main requirements are high strength, high toughness, and good wear resistance. Cold working mold steel is used. Cr12MoV is an excellent material with good service performance, good processing properties, and a high price. 42CrMo is an alloy quenched steel with high strength, high toughness, and good wear resistance. It can operate below 500 degrees. T8, T10, 42CrMo, and Cr12MoV. From the development of CNC bending machine molds, from the late 19th century to the mid-20th century, CNC bending machine mold materials were mainly represented by high-speed steel. In 1927, Germany developed hard alloy CNC bending machine mold materials, which were widely used. In the 1950s, Sweden and the United States separately synthesized artificial diamonds, and the cutting of CNC bending machine molds entered a period represented by ultra-hard materials. In the 1970s, CNC bending machine mold customization adopted high-pressure synthesis technology to synthesize polycrystalline diamond (PCD), solving the problems of natural diamond and high cost, and expanding the application range of diamond CNC bending machine molds to aviation, aerospace, automotive, electronics, stone, and other fields.
Introducing some common causes of bending machine malfunctions:
One. The bending machine's pressure build-up is slow. 1. The pressure valve port may be clogged; 2. The pressure valve is not responsive; 3. Electrical issues: Test the solenoid pressure valve directly, or敲击 the core of the solenoid pressure valve; 4. High-pressure filter clog; 4. Impact during shutdown, guide plate loose; 5. Delay parameter setting too low.
2. Slider cannot move quickly. 1. Valve directly below has no signal or is clogged; 2. Electromagnetic proportional switching valve has no signal or the valve stem is not moving or stuck; 3. Mechanical parts, guide plate, and cylinder too tight; 4. Inflator valve closed and cannot be opened, thus unable to suck oil; 5. Dimension issue; 6. Foot switch not functioning; 7. After slowly supplying power to the valve, close the oil filling valve, Zhuhai CNC bending machine mold, unable to suck oil.
Three, the pause time at the slider speed switching points is long. 1. The preparation time for impact pressure is long, and there is air leakage in the intake pipe; 2. The flow of the supply valve and the self-priming pipe is small, or the slider speed is too fast, causing a vacuum; 3. The supply valve is not fully closed, leading to a pressure drop in the upper chamber; 4. After slowly supplying power to the valve, close the oil filling valve, and the upper chamber does not absorb oil; 5. Different position openings in the proportional valve; 6. Failure of the rapid deceleration test; 7. The size of the rapid downward pressure affects the closing of the oil filling valve, and rapid downward pressure can cause a long pause time; 8. Pressure parameter adjustment in the processing delay stage; 9. The throttle hole in the control pipeline of the filling valve is too small, causing a pressure difference; 10. Delay before parameter reduction in the CNC system; 11. Gain parameter reduction during deceleration in the CNC system.
