Embodiment Construction

[0031] Below in conjunction with accompanying drawing, take the 106F type automobile flange of Dongfeng Motor Corporation as an example to illustrate the present invention, as figure 1 , figure 2 , image 3 , the flange die forging forging process is as follows:

[0032] 1. Cutting: Adopt GB4025C band saw machine to cut φ85 round steel with a length of 163±1mm;

[0033] Since we adopt a closed-type non-flash forging process, the process has strict requirements on the blanking quality. The blanking length of the round bar blank must be strictly controlled, and the flatness of the end surface must also be strictly controlled. In order to avoid the phenomenon that the round bar blank is placed crookedly in the forging cavity and the forging is not full and the local flash occurs.

[0034] 2. Heating: Use KGPS300-1 medium frequency induction heating furnace to heat the round bar blank to the temperature required by the forging process;

[0035]3. Closed flash-free forging wit...

Abstract

The invention relates to a medium-heavy automobile flange die forging process and a punching and calibrating composite die thereof, which belong to a forging process in the field of manufacturing of machines, in particular to an automobile flange closed die forging process and a punching and calibrating composite die thereof. By the process and the composite die, the problems of low quality, a great number of production processes, low material utilization rate and the like of the conventional production process forgings are solved. The one-time finish forging forming of a closed finish forging die is used, the head of a die ejector beam is manufactured into a boss of the die, the web thickness is reduced, and punching and calibrating are completed in one step on the special punching and calibrating composite die. The punching and calibrating composite die comprises a calibrating male die, a female die, a punch, a belleville spring, a spring compression plate, a pull rod and the like. The die has low invested cost, a reasonable and simple process flow, high product quality, small machining amount and high productivity, and obviously lowers the production cost of products.

Description

technical field [0001] The invention belongs to the forging processing technology in the field of mechanical manufacturing, in particular to the forging technology of the closed die forging of the flange of the automobile and the composite mold for punching and correcting the same. Background technique [0002] The flange is a key structural part in the chassis system of the car. It is an important connecting part connecting the transmission shaft and the rear axle. It plays the role of connecting and transmitting force. The shape of the forging is simple, and the weight of a single forging is basically 2-8 kg. Therefore, the forging methods of each forging plant are different. At present, the representative forging production processes of domestic commercial vehicles, especially medium and heavy-duty vehicles, mainly include the following types: [0003] Production process of hot die forging press: On a hot die forging press with a tonnage of 1600T or below, the overall lig...
