Today, we introduce a new type of testing instrument, impact specimen notch four knife hydraulic broaching machine, which adopts the most stable hydraulic drive, and is equipped with four broaches, four knives and four working positions. Four standard notch samples can be made at one time by one process. It is the world's leading impact specimen notch broaching machine. Shandong HuiFu Automation Co., Ltd. is committed to the research and development of test instruments. The patented technology of gap broaching machine is more efficient. It is especially suitable for the metal material laboratory with continuous workload. It can double the work efficiency, save space and save manpower and material resources. It is a good helper for Charpy impact test. 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). It is widely used in metallurgy, boiler and pressure vessel, steel plate, steel pipe, wind power generation, hardware, metal, casting, pump, valve, solar energy, ordnance, fastener, diesel engine, electric power, iron tower, railway, shipping, machinery manufacturing, petroleum, automobile, chemical industry, aerospace, physical and chemical laboratory, scientific research and other departments.

Performance advantages:
The machine is mainly used to process the notch of metal pendulum Charpy impact specimen. 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. The broaching machine adopts the structure of four knives and four stations with international leading hydraulic transmission, electric control, four broach sample preparation and one-time broaching forming. The broaching machine has reliable processing quality, high uniformity of notch precision and double improvement of sample preparation efficiency. 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 50115 and other domestic and foreign standards.  
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.
