1 Performance characteristics ：
Csl-4y four knife impact specimen notch hydraulic broaching machine is mainly used to process metal pendulum Charpy impact specimen notch. It is a special auxiliary equipment of metal pendulum impact testing machine. It can make metal impact samples with different notch shapes according to the corresponding standards. This broaching machine adopts the structure of four knives and four working positions with international leading hydraulic transmission broach Sample preparation, one-time broaching forming, reliable processing quality and high uniformity of notch accuracy, sample preparation efficiency is doubled. It is the best matching equipment of metal pendulum impact testing machine.
The hydraulic drive makes the sample preparation process stable and reliable with low noise, avoids the influence of inappropriate broaching speed on the processing accuracy of sample notch, and is easy to operate and safe. It is a new product to replace the mechanical transmission broaching machine. Circulating lubrication, lubricating oil cooling, lubricating cutting edge and cleaning broach ensure that the prepared sample notch size and surface quality are of high standard and meet the use requirements. And prolong the service life of broach. It adopts national patent technology, double oil tank to filter hydraulic oil for four times, without circulating iron chips, to ensure high quality and high efficiency of the system. The processed V-notch and u-notch can meet gb2106-80 "metallic Charpy (V-notch) impact test method" and gb229-94-2007 "metallic Charpy (u-notch) impact test method" respectively. After relevant adjustment, they can meet the corresponding requirements of ASTM E23, EN10045, iso148, iso0083, DIN 50 115 and other domestic and foreign standards.
The broach is made of high-quality W18Cr4V tool alloy. The tool parameters are designed reasonably, with high hardness, good wear resistance and long service life. Each tool can process more than 20000 samples. This product is equipped with four position broach, which can process four sample notches at the same time: four V-shaped or U-shaped (2mm deep), two V-shaped and two U-shaped notches or three V-shaped and one U-shaped notch).
The main hydraulic components and electrical control parts are domestic famous brands, which fully ensure the reliability and stability of the hydraulic system. The frame part of the frame is welded by angle steel, channel steel and other profiles. The structure design is reasonable and conforms to the habits of operators. The panel and other parts are sheet metal structure, easy to disassemble and assemble, surface spray treatment, neat and beautiful appearance.
