Cold press machine tool components: oil pressure system, electrical control system, platen balance mechanism, platen and fuselage. The fuselage is welded by profile and plate steel with compact structure and good strength.

1. Oil pressure system: composed of oil cylinder, oil tank, oil pump, oil pump motor, control valve block and pressure gauge. The oil tank is equipped with oil, which is driven by the oil pump motor to pump oil. The oil is sent to the oil cylinder by connecting the oil pipe to make the oil cylinder work. Among them, the relief valve controls the hydraulic system to reach the pressure and acts as a safety valve to prevent the system from overload; the one-way throttle valve can make the pressure piece produce back pressure in the extrusion process, which plays a stable role. The electromagnetic ball valve is used to maintain the pressure set by the system, and the pressure gauge is used to show the pressure.

2. Electrical control system: it is mainly composed of main circuit and control circuit. Automatic circuit breaker, fuse and AC contactor are used in the circuit to protect the motor and solenoid valve of machine tool from overload, short circuit, voltage loss and under voltage.

3. Platen balance mechanism: mainly composed of balance lifting rack, lifting gear, rotating shaft and fixed rotating bearing. The left and right balance racks are installed on the fuselage, the lifting gears are fixed at both ends of the rotating shaft, and the bearings are installed at both ends of the rotating shaft, so that the rotating shaft can rotate flexibly. When the pressure plate is lifted and lowered, the lifting gear is not balanced, and the rack is meshed and rotated to keep the pressure plate balanced during the lifting process.

4. Pressing plate part: it is composed of upper and lower pressing plates. The upper and lower pressing plates are welded by profiles and steel plates. The working planes are all processed by large-scale gantry milling machine to ensure that the working plane is flat and smooth. The upper pressing plate is connected with the oil cylinder cylinder, and the lifting of the pressure plate is realized by the lifting and lowering of the oil cylinder. The lower pressing plate is directly welded on the base of the machine body to make the whole structure tight.
