Woodworking Cold Press – 3D Model SolidWorks

1. Introduction to cold press
1 Components of the machine tool: hydraulic system, electrical control system, pressure plate balance mechanism, pressure plate and machine body. The machine body is welded from profiles and plate steel, with compact structure and good strength.
1. Hydraulic system: It consists of oil cylinder, oil tank, oil pump, oil pump motor, control valve block and pressure gauge. The oil tank is filled with oil, which is driven by the oil pump motor to pump oil, and the oil is sent to the oil cylinder through the connecting oil pipe to make the oil cylinder work. Among them, the overflow valve controls the hydraulic system to reach pressure and plays the role of a safety valve to prevent the system from being overloaded; the one-way throttle valve can generate back pressure in the extrusion process and play a stabilizing role. The electromagnetic ball valve is used to maintain the pressure set by the system, and the pressure gauge is used to display the pressure.
2. Electrical control system: It is mainly composed of the main circuit and the control circuit. The circuit uses automatic circuit breakers, fuses, and AC contactors to implement overload, short circuit, pressure loss and undervoltage protection for machine tool motors, solenoid valves, etc.
3、 Platen balancing mechanism: mainly composed of balanced lifting rack, lifting gear, rotating shaft and fixed rotating bearing. The left and right two balancing racks are installed on the machine body, lifting gears are fixed at both ends of the rotating shaft, and bearings are installed at both ends of the rotating shaft so that the rotating shaft can rotate flexibly. When the platen is lifted or lowered, the lifting gear meshes and rotates with the balancing rack, so that the platen always keeps balance during the lifting process.
4、 Platen part: It consists of an upper platen and a lower platen. Both the upper and lower plates are welded from profiles and steel plates. The working planes are finely processed by a large gantry milling machine to ensure that the working plane is flat and smooth. The upper platen is connected to the cylinder rod of the oil cylinder. The lifting and lowering of the platen is realized by the lifting and lowering of the oil cylinder. The lower platen is directly welded to the base of the machine body, making the whole machine structure tight.
