The processing flow of cake type forging is introduced

What is the specific processing process of cake forging? Cake type satin parts are also called short shaft type forgings, and their processing process can be divided into ordinary forgings and high hub and deep holes according to the degree of forming difficulty
Forgings and high-ridged thin-wall complex forgings and other three cases, the processing process is generally upsetting, vertical upsetting to gasification skin, final forging, let's look at the specific introduction of this aspect.
1, ordinary cake forging processing flow:
This kind of forgings such as gears, flanges, ten axis, etc., are relatively simple in shape. The oxide skin on the cylinder surface of the billet was removed by upsetting, and then the billet was turned over 90° and set up gently upsetting
Press to remove the oxide skin on the end face. The diameter of the billet after upsetting should exceed the spokes and reach the middle of the rim, so that folding does not occur and the hub can be filled. Bread class forging
The diameter of the parts is large, and two forging hammers can be used for joint forging when no upsetting table is arranged on one forging hammer. One hammer upsetting, the other hammer forging,. Without affecting the forging filling, the upsetting diameter is as close as possible to the final forging, so that the billet positioning in the final forging is accurate and folding can be avoided.
2, high hub deep hole cake forging processing flow:
This kind of forgings in the processing in order to make the blank in the final forging forging neck easy to locate, so that the hub is full of upsetting forming step, advance forging concave hole, turn 180° after the final forging.
3, ribbed thin-walled cake forging processing flow:
To ensure that the forgings are full or to avoid folding, these forgings need to improve the metal flow conditions using pre-forging steps. For larger diameter circular parts, folding may occur without pre-forging. After pre - forging, the forming conditions are improved. But in a forging hammer sometimes layout can not open, need to use two forging hammer joint forging.

What is the processing flow of cake forging? The above is the relevant introduction of this aspect, I hope to help you.
