　　电动液压冲片机操作规程：

　　★使用前**先向油箱内加注6L液压油（打开后盖板加油），检查各种有关接头盒紧固件是否动，如有松动则拧紧即可，以防漏油，影响使用，检查电气系统接地，熔丝是否有效。

　　★开始时，将手动杆至中间停止位置，然后按面板上启动按钮，接通电源，油泵开始工作，搬动手动杆使活塞上升一段距离，观察有无卡滞等异常现象，如有，侧停机检查，排除，如无异常现象应使活塞上升一段距离再下降，这样往返几次以排尽缸内的空气，观察油管内无气泡**可正常使用。

　　Electric hydraulic punching machine operating rules:

　　★Before use,fill 6L hydraulic oil into the fuel tank(open the rear cover and fill it with oil),check whether the various joint box fasteners are moving,and tighten them if they are loose to prevent oil leakage and affect the use.Check that the electrical system is grounded and that the fuse is valid.

　　★At the beginning,move the manual lever to the middle stop position,and then press the start button on the panel to turn on the power.The oil pump starts to work.Stop inspection and eliminate,if there is no abnormal phenomenon,the piston should be raised for a certain distance and then lowered,so as to return several times to exhaust the air in the cylinder,and observe that there are no air bubbles in the oil pipe.

　　电动液压冲片机结构与工作原理：

　　★本机主要机架、液压系统级电气系统等组成。

　　★机架部分：主要由横梁、立柱、托盘、油缸、外壳、底座等组成。

　　★液压系统：由液压泵、转换阀、油箱、滤油器及油管、接头组成。液压泵为轴向柱塞高压泵，流量为2.5m3/min额定压力31.5 Mpa，由1500KW三相电机直接驱动，固定在底座上。

　　★转换阀装在前面板的右侧，由手动杆操作。向上提油缸上升，向下按油缸下降，中间为停止。

　　★溢流阀设在机壳内。溢流阀是调节压力范围的，此项程序在出厂前已调试好，A随意调节。

　　Structure and working principle of electric hydraulic punching machine

　　★This machine is composed of main frame and hydraulic system-level electrical system.

　　★Frame part:It is mainly composed of beams,columns,trays,oil cylinders,shells,bases,etc.

　　★Hydraulic system:It consists of hydraulic pump,switching valve,fuel tank,oil filter,oil pipe and joint.The hydraulic pump is an axial piston high-pressure pump with a flow rate of 2.5m3/min and a rated pressure of 31.5 Mpa.It is directly driven by a 1500KW three-phase motor and fixed on the base.

　　★The switching valve is installed on the right side of the front panel and is operated by a manual lever.Lift the oil cylinder upwards,press the oil cylinder downwards,and stop in the middle.

　　★The overflow valve is set in the casing.The relief valve adjusts the pressure range.This program has been debugged before leaving the factory.A can be adjusted at will.

　　电动液压冲片机机维护与保养：

　　仪器内外应保持清洁，防止各种部分生锈。

　　经常检查油液洁净与否，根据使用情况每月应沉淀油箱内液压油一次，每半年更换液压油一次，换油时应彻底清洗油箱、滤油器、如平时发现油液混浊，严重不能再用时，应及时更换，否则会加速液压各部分磨损，甚至影响正常工作。液压油规格、视气温不同建议如下：

　　当环境温度为15±5℃时用GB443-84N46（相当于30号机械油）

　　当环境温度为25±5℃时用GB443-84N68（相当于40号液压油）

　　Maintenance and maintenance of electric hydraulic punching machine

　　The inside and outside of the instrument should be kept clean to prevent all parts from rusting.

　　Always check the cleanliness of the oil.Depending on the use situation,the hydraulic oil in the fuel tank should be deposited once a month and the hydraulic oil should be replaced every six months.When changing the oil,the fuel tank and oil filter should be thoroughly cleaned.When in use,it should be replaced in time,otherwise the hydraulic parts will be accelerated and even affect normal work.Hydraulic oil specifications and suggestions depending on the temperature are as follows:

　　When the ambient temperature is 15±5℃,use GB443-84N46(equivalent to 30#mechanical oil)

　　When the ambient temperature is 25±5℃,use GB443-84N68(equivalent to No.40 hydraulic oil)

　　电动液压冲片机注意事项：

　　★严禁不加油，使油泵空转。

　　★使用前必须排尽系统内空气，才能使用。

　　★冲压试件应注意油缸上升距离，严禁活塞与试件接触以防损坏机件，操作人员应特别注意。

　　★当做完试验后应将活塞降到底部以防活塞潮湿导致生锈。

　　★试验机器前必须阅读使用说明书。

　　Note for electric hydraulic punching machine:

　　★It is strictly forbidden to let the oil pump run without refueling.

　　★The air in the system must be exhausted before use.

　　★Pay attention to the rising distance of the cylinder when stamping the test piece.It is strictly forbidden that the piston contact the test piece to prevent damage to the machine.

　　★After the test is completed,the piston should be lowered to the bottom to prevent the piston from being wet due to rust.

　　★Read the instruction manual before testing the machine.
