Cake satin parts are also called short shaft forgings. The processing process is divided into three types according to the difficulty of forming: ordinary forgings, high-hub deep-hole forgings and high-rib thin-walled complex forgings. The processing process is generally upsetting. , Upsetting to gasification skin, final forging, let's take a look at the relevant introduction in this aspect.
1. Processing flow of ordinary cake forgings:
Such forgings, such as gears, flanges, Shiyu shafts, etc., have relatively simple shapes. The oxide skin on the cylindrical surface of the blank is removed by upsetting, and then the blank is turned 90° to stand up and lightly upset to remove the oxide skin on the end surface. The diameter of the blank after upsetting should exceed the spokes and reach the middle of the rim, so as not to fold and to fill the hub. The diameter of the cake forgings is large, and two forging hammers can be used for joint forging in the case that the upsetting table cannot be arranged on one forging bar. One hammer for upsetting and the other for final forging. Under the premise of not affecting the fullness of the forging, the upsetting diameter is as close to the final forging as possible, so that the positioning of the blank in the final forging is accurate and folding can be avoided.
2. Processing flow of high wheel deep hole cake forgings:
In order to facilitate the positioning of the blank in the final forging neck and fill the hub, the upsetting forming step is added during the processing of this type of forging, the concave hole is pre-forged, and the final forging is performed after turning 180°.
3. Processing flow of rib thin-walled cake forgings:
In order to ensure that the forgings are full or avoid folding, such forgings need to improve the metal flow conditions and use pre-forging steps. For rings with larger diameters, folds may occur without pre-forging. After pre-forging, the forming conditions are improved. However, sometimes it cannot be arranged on one forging hammer, and it is necessary to use two forging hammers for joint forging.
