Background

The cold header is a special device which mainly uses piers and is specially used for producing fasteners such as nuts and bolts in batches, while the crankshaft is a main connecting structure for power transmission of the cold header, and the crankshaft is the most important part in an engine. It takes the force from the connecting rod and converts it into torque to be output by the crankshaft and drive other accessories on the engine. The crankshaft is subjected to the combined action of centrifugal force of the rotating mass, gas inertia force of periodic variation and reciprocating inertia force, so that the crankshaft is subjected to the action of bending and twisting load. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the surface of the journal needs to be wear-resistant, work uniformly and balance well.

The oil supply mode of the cold header is that an oil hole is drilled on the output connecting rod for supplying oil, and the output connecting rod is arranged inside the cold header and in the idle range of the main sliding block of the cold header. When the cold header operates, the output connecting rod moves up and down and back and forth by means of eccentric rotation of the crankshaft. The existing oil pipe for supplying oil on the output connecting rod is very easy to be blocked by fragments generated by the work of the cold header in the working process, so that the oil supply of the oil pipe for supplying oil is not smooth, the normal work of the cold header is influenced, the output connecting rod is excessively worn, and even the output connecting rod is broken.
