Embodiment Construction
[0017] see figure 1 , a forging process of a bell shell, comprising the following steps:
[0018] a. In the rough forging process, the billet is first put into the intermediate frequency furnace for heating, and the billet heated by the intermediate frequency furnace is directly put into the rough forging die 1, and the rough forging punch 2 is forged, and the inner cavity of the rough forging die 1 is divided. In order to locate the part and the flow part, the rough forging punch 2 is connected by an M24 inner hexagonal bolt, and the rough forging die handle 5 is arranged under the rough forging die 1;
[0019] b. Precision forging process, put the blank after rough forging into the precision forging die 3, and forge it into shape, wherein, the precision forging punch 4 and the precision forging die 3 adopt a split structure, and the bottom of the precision forging die 3 Equipped with precision forging die handle 6.
[0020] The inner cavity of the rough forging die is divi...

The invention discloses a forging technology of a bell housing. The forging technology of the bell housing comprises the following operation steps of a rough forging process and a finish forging process. According to the rough forging process, a blank is put in an intermediate frequency furnace to heat, the blank heated by the intermediate frequency furnace is put into a rough forging die, rough forging punch pin forging is carried out, the inner cavity of the rough forging die is divided into a locating part and a material flowing part, and the rough forging punch pin is connected through an M24 inside hexagonal bolt. According to the finish forging process, the blank after the rough forging is put in to a finish forging die to forge, wherein a finish forging pin and the finish forging die adopt a split structure. The forging technology of the bell housing shortens the route of product manufacturing process, and effectively improves producing efficiency. The rough forging adopts closed type forging, precision of products is stable, a great number of raw materials can be saved, the manufacturing cost of the products is greatly reduced, the novel technology eliminates an air hammer process, the working environment of workers is effectively improved, and the quality of the products is reliably guaranteed.
Description
technical field [0001] The invention relates to the fields of mechanical manufacturing and moulds, in particular to a forging process of a bell-shaped shell. Background technique [0002] The forging of bell-shaped shells is very common in our country, but the traditional air hammer forging process is used at present. The whole process is as follows: the billet is heated to 1050°C by an intermediate frequency furnace, and then the rough forging process is carried out in two processes, that is, firstly use After the air hammer forges the stem, the head is flattened by a mechanical press before being forged into shape. [0003] The new process is: the billet is heated to 1050°C by an intermediate frequency furnace, and the pre-forging is directly completed in the rough forging die, and then the precision forging is formed. [0004] Due to the high noise and vibration of the air hammer, the working environment of the workers is harsh, and the quality of the product is comple...
