Cold-pressed forging piece connecting piece

Technical Field

The utility model relates to the technical field of forgings, in particular to a cold-pressed forgings connecting piece.

Background

The forging is a processing flow. Forgings are articles in which metal is forced to shape by plastic deformation into a desired shape or a suitable compressive force. Such force is typically achieved through the use of a hammer or pressure. The forging process builds an exquisite particle structure, improves the physical properties of metal, and generally adopts a solution quenching treatment process to improve the comprehensive properties of strength, toughness, corrosion resistance, fatigue resistance and the like of the ultra-large 7050 aluminum alloy forging, but large quenching residual stress is easily introduced into the forging in the quenching cooling process, so that the static strength, the stress corrosion resistance, the fatigue resistance and the like of the material are influenced, and the size and shape stability of a component in the subsequent mechanical processing are reduced. Therefore, the effect and mechanism of reducing the quenching residual stress of the forging can be achieved by using a segmented cold pressing process.

The forging that adopts segmentation cold pressing technology to be used for connecting has cylinder head, main journal, bent axle end flange output end axle, connecting rod, piston head, cross pin axle, crank drive gear, ring gear, intermediate gear and the oil-dyed pump body etc. above-mentioned forging such as ring gear is used for transmitting kinetic energy, and when transmitting kinetic energy, can accompany the heat, when the high temperature, the high temperature can lead to the forging to take place deformation to above-mentioned forging such as ring gear does not be equipped with the louvre, and the heat dissipation is slow, and general ring gear and ring gear pivot need be fixed through bolt and nut, connect more troublesome. In view of this, we propose cold forging connectors.
