Advantages of Henli Press Machine

Slider guide adopts “high-frequency quenching” and “rail grinding process”; high-frequency quenching: hardness reaches above HRC 48 degrees, guide rail grinding process: surface finish can reach mirror degree Ra0.4, plane height reaches 0.03mm/m*m.
Advantages: low wear, high precision, long precision keeping time and long life. Gear shaft is made of high-strength alloy material 42CrMo, all tooth surfaces are treated with medium frequency, high hardness; tooth surface grinding processing, high precision.
Advantages: small tooth surface wear, high precision of tooth surface engagement and long service life. Ball seat material: sintered TM-3 copper alloy ball seat, the general manufacturer ball seat is ductile iron.
Advantages: High-strength TM-3 copper alloy ball seat, the surface pressure strength is up to 100kgf/cm*cm. During the pressing process, the ball seat and the serrated tooth ball head greatly reduce the chance of jam and prolong the service life. All the copper sleeves of the QIAOSEN press are made of tin phosphor bronze ZQSn10-1, and the general manufacturer uses BC6 (Sen 6-6-3) copper.
Advantages: The strength is 1.5 times higher than that of ordinary BC6 copper, the strength is high, the wear is small, and the precision is kept for a long time. Where the collar is in contact with the oil seal, the surface of the collar is ground and the surface is chrome-plated.
Advantages: the surface finish reaches between Ra0.4 and Ra0.8, it is not easy to leak oil when it comes into contact with the oil seal, and the surface is chrome-plated. The hardness is up to HRC of 48 degrees or more, ensuring long-term use without wear and longer service life of the oil seal. The crankshaft is made of high-strength alloy material 42CrMo, and the general manufacturer’s crankshaft is made of 45 steel material.
Advantages: The strength is 1.3 times higher than that of 45 steel, the service life is longer, and the probability of breaking the crankshaft is greatly reduced. The standard of QIAOSEN crankshaft is produced by professional crankshaft manufacturers(after strict forging, heat treatment, flaw detection, processing, inspection and other perfect processes) to ensure that various quality problems of the crankshaft during the production process are avoided and the quality of the crankshaft is ensured. Wheel static balance test platform, each flywheel is static balance test to ensure that the flywheel reduces the shaking of the press when it is running at high speed. All of QIAOSEN’s open single-point and double-type double-point crank presses, standard oil pressure lubrication pipes are used in diameter 6(other manufacturers generally use diameter 4),the oil pressure lubrication piping of medium and large punch adopts all diameter 8.
Advantages: the pipeline is long, the large passage diameter is not easy to block and rupture, ensuring the safety of the lubricating oil road. In order to ensure that the accuracy can reach the Japanese JIS1 standard, eliminate machining errors, and accumulate errors in assembly, we have specially designed a grinding machine for grinding and repeated grinding to ensure that the precision meets the JIS1 standard, and some local precision even reaches JIS premium standard.
