In the parallel oil circuits, the power output or movement speed of different actuators can be achieved by controlling the flow rate of each oil circuit. Typically, the parallel oil circuits of the stamping press are controlled by control elements such as solenoid valves and proportional valves. In order to make full use of the waste heat of the stamping press, a heat exchange device is added to the parallel oil circuit to realize the recovery and utilization of waste heat. Specific connection methods include the following: adding a plate heat exchanger to the parallel oil circuit: Plate heat exchangers have the characteristics of compact structure, high heat transfer efficiency, and easy cleaning, and are suitable for use in hydraulic systems. In order to make full use of waste heat, the heat exchanger can be installed near the waste heat generation part, such as the oil circuit of the hydraulic cylinder or motor. This maximizes heat exchange efficiency. When connecting the heat exchange device, the system's pressure and temperature requirements must be confirmed. The heat exchanger should be able to withstand the system's working pressure and adapt to heat exchange needs under different temperature environments.
