8. Unloading workbench and receiving rack
The blanking workbench is composed of a blanking gantry, a lowering roller, a lowering clamp, a guiding device, an automatic pushing device and a receiving device. The feeding platform is placed on the blanking base, and about 20 sets of cutting rollers are arranged on the blanking rack to form a working surface for conveying the sheet material, where the clamp feeding mechanism is installed, and the rack and pinion transmission mode is adopted. Guide rail. After the sheet has been processed, the clamps will automatically run to the appropriate blanking position. At this time, the cutting clamp stops moving, the jaws open, and the pushing device moves, and the sheet is smoothly pushed into the receiving frame. The blanking workbench mainly provides a carrier for facilitating the installation of the clamp feeding device and the operation of the sheet material.
Hydraulic system
The hydraulic system oil of this machine is composed of two small hydraulic system oil passages, which are the power head hydraulic system and the upper and lower material hydraulic systems. The main cylinder of the power head hydraulic system is a composite cylinder with a two-speed dual-force function, which not only improves the punching efficiency, but also saves energy. The main cylinder control valve is a German hydraulic servo control valve and position sensor, which can adjust the running position of the slider up and down to reduce the noise during stamping. This valve has a special control card that adjusts the slider's rise and fall by adjusting the parameters on the control card.
The upper and lower material hydraulic system includes two clamp cylinder oil passages, one loading oil passage and one guiding device oil passage. The series cylinders form a synchronous cylinder to ensure the synchronous lifting of the two lift cylinders.
The pressure detection switch and the liquid level control relay are included in the main oil passages of the two hydraulic systems. When the pressure is too high or the liquid level is lower, the numerical control system alarms to protect the hydraulic system.
Conclusion
SPT120-12A type automobile longitudinal beam numerical control flat punching line is one of the most popular CNC flat plate punching lines in China. Compared with the current open bed equipment, it is easier to manufacture and assemble; closed bed It can ensure the stability of equipment accuracy and the long-term life.
