1、 Overview of Charpy impact specimen notch automatic broaching machine:
According to the different shape of the metal impact machine, the special equipment is used to make metal impact samples. Hydraulic transmission, electric control (solenoid valve reversing control broach lifting), controllable speed regulation (speed regulating valve can adjust different cutting speed), and lubricating oil is used to cool and lubricate cutting edge to ensure that the prepared sample notch size and surface quality are of high standard and meet the requirements of use. The broach is made of high quality W18Cr4V alloy, which has a long service life. The equipment is stable and reliable, easy to operate and high efficiency of sample preparation. It is the best matching equipment for metal pendulum impact testing machine.
The hydraulic transmission makes the sample preparation process stable and reliable, the noise is small, the notch processing accuracy is high, the operation is simple and safe, the shape is beautiful, the time and labor saving, and the sample preparation is accurate. According to the actual use needs, it can be configured according to the user's requirements to configure any two middle and sample notches of V-shaped, U-shaped 2mm, U-shaped 3mm and U-shaped 5mm notches. It only takes 8 seconds, and the operation is extremely simple and reliable. It is widely used in measurement and quality inspection; metallurgy and steel; machinery manufacturing; automobile production; colleges and universities; scientific research laboratory; commodity inspection and arbitration, technical supervision departments and other industries.
 
2、 Host structure:
3.1 working part of the host: the broach positioning seat of this machine is universal, and can be easily replaced with other special Broaches for special notches according to the special needs of users;
3.2 main engine driving part: the cylinder is controlled by the button on the workbench to make the broach positioning seat and broach move up and down at a reasonable broaching speed of 2.5m/min;
3.3 power transmission, with the advantages of stable loading, low noise, self-lubricating, and over-voltage protection function;
3.4 electrical control part: it has the characteristics of automatic shutdown in place, which ensures the efficiency and safety of use.
3.5 lubrication and cooling part: the machine tool cooling pump is used for oil supply, and the oil quantity adjusting device is designed, which can easily adjust the direction and size of oil flow. After passing through the throttle valve, the oil from the cooling pump is sent to the guide rail for lubrication;
3.6 auxiliary part of the main engine: auxiliary devices such as lubricating oil filtering and scrap iron collection are provided to ensure safe and efficient processing, and at the same time, the internal environment of the machine is clean and iron chips are easy to be removed.
