The machine has an independent power mechanism and electrical system. It adopts button centralized control and can realize three working modes: adjustment, manual and semi-automatic: the working pressure of the machine, the pressing speed, the stroke and range of no-load fast down and deceleration, all can be based on the process It needs to be adjusted and can complete the ejection process. There are three process methods: ejection process and stretching process. Each process is a fixed pressure and fixed process. Two process actions are available for selection. The fixed pressure forming process has Ejection delay and automatic return.
Independent power organization and electrical system, and the use of buttons for centralized control, can complete the adjustment and semi-automatic operation methods. Its mobile workbench is driven by a variable frequency controller, and its electrical uses the world's leading PLC programmable controller. The innovation of the description and production of the YH25-315D "T"-shaped mobile workbench is conducive to improving the automation of the series of hydraulic presses, increasing the output power, and reducing the labor intensity of the operators.
Use liquid as the medium to transfer energy, adopt advanced hydraulic circuit of mother and child cylinder, low oil temperature, idle stroke speed above 10MM/s, working speed below 20 MM/s, equipment standby, noise when sliding fast up and down It does not exceed 75 decibels and adopts a four-column three-plate structure. The vertical accuracy of the movable plate is controlled by four precision guide sleeves. The parallel accuracy of any point on the lower working surface and the upper working surface is below 0.08MM.
1. Reduce quality and save materials. For typical parts such as automobile engine brackets and radiator brackets, hydroformed parts can be reduced by 20%-40% compared to stamping parts, and for hollow stepped shaft parts, the weight can be reduced by 40%-50%.
2. Reduce the number of parts and molds? Reduce mold costs. Hydroformed parts usually only need one set of molds, while most stamping parts require multiple sets of molds. The number of hydroformed engine bracket parts has been reduced from 6 to 1, and the number of radiator bracket parts has been reduced from 17 to 10.
3. It can reduce the amount of welding for subsequent machining and assembly. Take the radiator bracket as an example, the heat dissipation area has increased by 43%, and the number of solder joints has been reduced from 174 to 20. The number of processes has been reduced from 13 to 6, and the productivity has increased by 66%.
4. Improve strength and rigidity, especially fatigue strength. For example, a hydroformed radiator bracket can increase its rigidity by 39% in the vertical direction and 50% in the horizontal direction.
5. Reduce production costs. According to the statistical analysis of the applied hydroformed parts, the production cost of hydroformed parts is reduced by an average of 15%-20% compared with stamping parts, and the mold cost is reduced by 20%-30%.
