Embodiment Construction

[0020] The present invention will be further described below in conjunction with embodiment (accompanying drawing):

[0021] Such as figure 1 , 5 , 6, and 7, the multi-directional numerical control linkage forming process of a transmission planet carrier according to the present invention is through the upper punch 1, the front punch 4, the rear punch 8, the left punch 7, the right punch 35 The heated metal bar is formed by CNC linkage in two directions, realizing single station, one-time heating, multi-directional forming precision forgings of transmission planetary carrier with complex shape; front punch 4, rear punch 8, left punch 7 in the mold , The right punch 3 is placed in the four side square holes in the die 6, and it will not be disengaged during the forming process; to ensure its positioning accuracy, the die 6 adopts a split structure, which is easy to install and replace. It only needs to replace the more severely worn modules, which can not only reduce the mold...

Abstract

The invention discloses a multi-directional numerical control linkage precision forming process of a transmission planetary carrier. The process is characterized in that a heated metal bar is formed through numerical control linkage of an upper punch, a front punch, a rear punch, a left punch and a right punch in five directions, and a precise forging of the transmission planetary carrier with thecomplicated shape is prepared in a single station and through one-time heating and multi-directional forming; and the front punch, the rear punch, the left punch and the right punch in a die are arranged in four side square holes in a female die, and are not separated all the time in the forming process. The forging forming planet carrier forge piece is small in machining allowance, the production efficiency is greatly improved, the cost can be reduced to a great extent, and a certain foundation can be laid for mass production of the current part.

Description

technical field [0001] The invention relates to a multi-directional numerical control linkage precision forming process method for a transmission planet carrier, which belongs to the field of thermal processing of metal materials. Background technique [0002] The planetary frame of the automobile transmission is an important part in the transmission. At present, the forming of this part mainly depends on the CNC machining center for processing. However, due to the difficulty in positioning when processing the four side square holes, the processing time is long and the cost is high, which not only causes a serious waste of raw materials. , tool wear, etc., will also cause the metal flow line to be cut off, resulting in a reduction in the strength and life of the part. There are also some manufacturers that form the head shape by ordinary forging, but the four side square holes cannot be formed by forging, resulting in a large subsequent processing allowance, and the above-me...
