摘要

为了解决采用背压阀调压的大型压力机液压垫系统工作中油温过热的问题，提出了一种无需背压阀调压的伺服液压垫系统。该系统压边力控制采用伺服电机驱动液压马达的形式，将原本进入油液的热量转移到电机的制动电阻上，从而解决了系统液压油温过高的问题。以某型液压垫系统为例，采用AMESim软件对伺服液压垫系统及采用背压阀控制压力的液压垫系统的传热进行了分析计算，并进行了实验验证。结果表明：相比背压阀控制液压垫压力的系统，伺服液压垫系统可较大的减少系统油液的发热量。压力机在炎热的夏季连续工作2 h，伺服液压垫压力调节元件排油侧油液温度也不会超过50 ℃，较背压阀控制液压垫压力的系统温度低31.77%。

Abstract

In order to solve the problem of excessive oil temperature in the large press die cushion system with the relief valve, we propose a servo die cushion system without relief valve. In this system, the blank holder force is controlled by a servo motor-driven hydraulic motor, and the heat that originally enter the oil is transferred to the brake resistance of the motor, thus the problem of the excessive oil temperature in the system is solved. Taking a type of die cushion system as an example, we analyze and calculate the heat transfer of the servo die cushion system and the die cushion system with relief valve by AMESim software, and verify it by experimens. The results show that compared with the relief valve controlled die cushion ystem, the servo die cushion system can greatly reduce the system fluid heat. When the large press works continuously for 2 hours in hot summer, the oil temperature on the drain side of the pressure adjustment elements for the servo die cushion system does not exceed 50 ℃, which is 31.77% lower than the temperature of the die cushion system with the relief valve at the same conditions.
