Uses: Used for agricultural tractor products. The transmission shaft of the main tractor to output power to farm tools mainly bears torque. In order to protect tractors and farm tools, this piece is a relatively weak building, parts, and wearing parts, and the strength requirements cannot be too high or too low. Features: It is a kind of transmission shaft parts. The two ends of the shaft are respectively connected with tractors and farm tools, and have the characteristics of quick change and quick link, the requirements for matching spline and outer circle diameter are high, the strength has upper and lower limits, and the requirements for materials and heat treatment are very high. Process requirements: Blanks are generally made of steel bars or forgings. The main processes include quenching and tempering-turning-knurling-induction quenching-grinding and other processes. The main processing equipment includes numerical control lathe, numerical control cylindrical grinder, quenching equipment and gear hobbing machine equipment. Key inspection items: spline, surface roughness, appearance, coaxiality, cylindricity and other items; Key inspection equipment: special spline inspection tool, large and medium-sized precision coordinate measuring machine;

Uses: Used for agricultural tractor products, mainly bearing pulling force, transmitting brake signals to brake devices through brake pull rods to realize tractor braking; Features: It is a kind of long rod parts, with connecting interfaces at both ends of the shaft, and the pull rod consists of two sections. The two sections of rods are generally one long and one short, and one end of each section of rod is threaded and the other end is provided with two lifting lugs. The two sections are connected by a long stud in the middle and can be adjusted in length; process requirements: tie rods are generally made of bar stock, usually made of steel bar stock, welded with two lifting lugs, and galvanized as a whole. The main processes include: blanking-turning-welding-electroplating and other processes; Studs are generally made of nuts with hexagonal tubes. The main processes include blanking-turning-electroplating and other processes. The main processing equipment includes numerical control lathe equipment. Key inspection items: thread gauge, appearance and other items; Key inspection equipment: special thread inspection tool;
