Example 1

The utility model discloses a work process that is used for automatic transfer mechanism of commercial car connecting rod forging as follows:

(1) the transfer mechanism moves forwards to clamp the forge piece: the walking beam 1 is changed into a clamping state from an opening state, the lower-layer clamp fingers 2 support the workpiece on the station, the lower-layer clamp fingers adopt a profiling structure, namely the edge shape of the clamp fingers is designed according to the appearance of the connecting rod type forge piece, so that the generation of collision injury can be prevented, the parameters of ejection height of equipment, forging flash thickness and the like need to be familiar, and the interference between the clamp fingers and the forge piece is prevented.

(2) The transfer mechanism moves upwards to support the forge piece: the walking beam 1 is lifted, the lower layer of clamp fingers 2 support the forge piece, and the lifting height is noticed.

(3) The transmission mechanism moves the forging left and right: the walking beam 1 moves leftwards, the clamp fingers transmit the workpiece to the next station, the upper clamp fingers 3 play a limiting role at the moment, the forge piece is prevented from sliding off in the transverse moving process, the upper clamp fingers at the front end and the rear end of the forge piece are different, one is used for limiting leftwards and rightwards, and the other is used for limiting upwards and downwards. In the process, attention needs to be paid to the distance between the upper-layer clamp fingers 3 and the lower-layer clamp fingers 2, so that interference with the flash of the forge piece is avoided;

(4) the transfer mechanism moves downwards to put down the forging piece: the walking beam 1 falls down and the clamp fingers place the forging on the die.

(5) The transmission mechanism moves backwards to loosen the forged piece: the walking beam 1 becomes the open state, the clamp fingers leave the workpiece, and the workpiece falls into the cavity. And then the walking beam 1 is restored to the initial position, the forgings are sequentially and circularly transferred to the next station, and finally the whole forging process is finished. Simultaneously, in this example, the transmission device can transmit the forging of three process steps simultaneously, has promoted production efficiency greatly.
