Description

Electrified-controlled crankshaft multi-channel pre-forging operation system

Technical Field

The invention relates to a crankshaft forging operation system, in particular to an electrified-controlled crankshaft multi-channel pre-forging operation system, and belongs to the field of crankshaft production equipment application.

Background

The crankshaft is the most important component in the 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 crankshaft can be processed by casting or forging, the casting structure has no forging structure and stable performance, the casting structure has the defects of a series of sand holes, looseness, segregation and the like, the forging structure can be uniform, the defects of raw material structures and the like are eliminated, and the conventional crankshaft production is forged by adopting a stamping process to obtain the crankshaft with better mechanical property.

In the forging process, a bar is usually used as a blank, in order to ensure the forming quality of a crankshaft part, a pre-forging process is added before finish forging, in the pre-forging process, plane punching needs to be carried out on the square two sides of the blank, the bar-shaped blank is punched into a plane shape, an oil hole is punched in the plane-shaped blank by using a milling groove punching die, and then a multi-throw plane punching die is used for forging to form a multi-throw plane shape, so that the pre-forging is completed.

The large crankshaft can be assisted by cranes such as a gantry crane and the like in the forging process, while the small crankshaft is operated manually in the pre-forging process, but because the environmental temperature of the pre-forging of the crankshaft is relatively high and the temperature of the blank adopted by the pre-forging is also high, the phenomena that operators are injured due to improper operation, sunstroke is caused due to overhigh environmental temperature and the like can be caused in the manual operation; in addition, when the multi-throw plane forging stamping die is used for stamping, the oil hole needs to be placed in the middle of the multi-throw plane forging stamping die to improve the product precision, the stamping precision of manual operation can only reach 85% at most, a part of products are still crushed by the multi-throw plane forging stamping die due to inaccurate position placement, and the production efficiency of the products cannot be improved.
