冲击试样缺口拉床是一种常见的冲击试验设备，通常和冲击试验低温槽、冲击试验缺口投影仪、冲击试验机等配套使用，专门用于冲击试样缺口的加工，可分为手动冲击试样缺口拉床、电动冲击试样缺口拉床、液压冲击试验缺口拉床等。关于冲击试样缺口拉床你们的了解有多少呢?下面小编来给大家介绍一下冲击试样缺口拉床的规范操作步骤以及维护保养方法。
Impact specimen notch broaching machine is a kind of common impact test equipment. It is usually used together with impact test low temperature groove, impact test notch projector, impact testing machine and so on. It is specially used for processing impact sample notch. It can be divided into manual impact specimen notch broaching machine, electric impact sample notch broaching machine, hydraulic impact test notch broaching machine, etc. How much do you know about the impact sample notch broaching machine? The following small series will introduce the standard operation steps and maintenance methods of impact sample notch broaching machine.
1、接好电源线，电源是380V/50Hz，在机箱中加入适量的液压油加少了动力不足，46#或是68#抗磨液压油就可以，大约40升。
1. Connect the power cord. The power supply is 380V / 50 Hz. Add proper amount of hydraulic oil into the case. If the power is not enough, 46 × 10 or 68 × 10 anti-wear hydraulic oil can be used, about 40 liters.
2、点击控制面板上的电源启动按钮，查看一下电机是否顺时针转动，确认无误后，按拉刀上升和下降运行一下设备。让整个油路循环排出空气。
2. Click the power start button on the control panel to check whether the motor rotates clockwise. After confirmation, press the broach to rise and fall to run the equipment. Let the whole oil circuit circulate to exhaust air.
3、冲击试样缺口拉床运行良好后按拉刀上升键，准备好干净的试样，试样尺寸10(7.5,5)×10×55，用两边的夹紧装置夹紧试样。
3. After the notch broaching machine of impact sample runs well, press the broach rising key to prepare clean sample with sample size of 10 (7.5,5) × 10 × 55, and clamp the sample with clamping device on both sides.
4、按拉刀下降，试验自动完成，这个过程仅需8秒钟就可以完成。
4. Press the broach to drop, and the test is completed automatically. This process can be completed in 8 seconds.
5、冲击试样缺口拉床做完实验及时关闭设备电源，先关闭油泵电源再关闭设备电源。
5. After the experiment of impact sample notch broaching machine is finished, the power supply of the equipment shall be turned off in time, and the power supply of the oil pump shall be turned off first, and then the power supply of the equipment shall be turned off.
6、实验室要保持整洁干净，如果灰尘比较大要找个机衣盖住缺口拉床防止灰尘进入油箱。
6. The laboratory should be kept clean and tidy. If there is a lot of dust, cover the gap broaching machine to prevent dust from entering the fuel tank.
1、清洁冲击试样缺口拉床外表、导轨，修光毛刺，无锈蚀。
1. Clean the surface and guide rail of impact sample notch broaching machine, smooth the burr and ensure no rust.
2、检查拧紧手柄、螺钉、螺帽。
2. Check the tightening handle, screw and nut.
3、检查冲击试样缺口拉床压力阀不受潮，保持灵敏可靠。
3. Check that the pressure valve of impact sample notch broaching machine is not affected by moisture and keep sensitive and reliable.
4、检查油质、保持良好，清洗油池。
4. Check the oil quality, keep it in good condition, and clean the oil pool.
5、检查拉杆、螺杆、导轨是否拉毛。
5. Check whether the pull rod, screw and guide rail are rough.
6、调整各部塞铁间隙。
6. Adjust the clearance of plug iron of each part.
7、清洗检查冲击试样缺口拉床油泵、轴承及各阀类元件。
7. Clean and inspect the impact sample notch broaching machine oil pump, bearing and various valve components.
8、清洗冷却液，无铁屑，无杂物。
8. Clean the coolant without iron filings and foreign matters.
9、管路畅通清洁，牢固。
9. The pipeline is smooth, clean and firm.
10、根据情况调换冷却油。
10. Change the cooling oil according to the situation.
