Automatic production line for hot forging and trimming of steering knuckles

Abstract

The invention relates to the technical field of steering knuckle forging, in particular to an automatic production line for hot forging and trimming of steering knuckles. The automatic production line comprises a finish forging press, a trimming press, a finish forging die and a trimming die, the trimming die comprises an upper trimming die and a lower trimming die, and a transfer channel is arranged between the finish forging press and the trimming press. A transfer device is arranged at the transfer channel, a feeding channel is arranged at one side of the finish forging press, a feeding device is arranged at the feeding channel, a material returning channel is arranged at one side of the trimming press, and a material returning device is arranged at the material returning channel. The transfer device is provided with a second clamp used for transferring workpieces from a lower finish forging die to the lower trimming die through the transfer channel, the material returning device is provided with a third clamp used for taking out the workpieces and flashes through the material returning channel, the structure is scientific, the production line is reasonably arranged, the second clamp and the third clamp are matched, automatic transfer is achieved, the production takt is accelerated, and the production efficiency is improved.

Description

Technical field [0001] The present invention relates to a steering knuckle forging technology, and in particular, to a steering knuckle trimming hot forging automatic production line. Background technique [0002] During the forge steering knuckle to go through pre-forging, finish forging, trimming and other processes, which processes are performed in the hot state, high requirements for tact, resulting in slow tempo to avoid temperature decrease can not be forged workpiece, and the workpiece structure complex, irregular shape, heavy weight, and high accuracy of the mold in the workpiece from the mold down, if not removed grasping grip, the workpiece is tilted or will affect the tact. In the prior art, typically using long-arm tool manual gripping, transport large, not only the labor intensity, high ambient temperature, and often impact processing step due to operational errors. Inventive content [0003] Object of the present invention is for the deficiencies of the prior art, ...

AI Technical Summary

Problems solved by technology

[0002] Automobile steering knuckles need to go through pre-forging, final forging, edge trimming and other processes during forging. This process is carried out in a hot state, which requires a high production cycle, so as to avoid the temperature of the workpiece being too slow and the temperature of the workpiece cannot be forged, and the structure of the workpiece Complex, irregular shape, heavy weight, and high precision of the mold, the production cycle will be affected if the workpiece is put down or taken out from the mold, if it cannot be grasped firmly, or the workpiece is tilted

In the prior art, manual operation of long-arm tools is generally used for gripping and transfer, which is not only labor-intensive and the ambient temperature is high, but also often affects the processing process due to operational errors
