Embodiment

[0209] 1. Cutting

[0210] refer to image 3 and Figure 3-a to Figure 3-e , according to the area of ​​each section on the blank is equal to the area of ​​the corresponding section on the forging plus the area of ​​the flash, which is shown in the following formula (1):

[0211] A j =A d +A f (1)

[0212] In the formula: A j Calculate the cross-sectional area of ​​the blank for any position;

[0213] A d is the cross-sectional area of ​​the corresponding forging;

[0214] A f is the cross-sectional area of ​​the corresponding flash; according to the size of the corresponding section of the triangular control arm and the size of the set flash, the section diameter of the largest part is taken as the diameter of the round bar is 115mm, and the length of the round bar is calculated as 132mm according to the principle of equal volume , using band sawing machine for cutting;

[0215] 2. Blank heating

[0216] Heat the billet obtained in step 1 in an electric induction...

Abstract

The invention discloses a forging forming method of a triangular aluminum alloy control arm and aims at solving the problems in the prior art of low quality of a product, low material utilization ratio and low production efficiency. The forging forming method comprises the following steps: 1, blanking; 2, heating a blank: heating the blank in the first step in an electric induction heating furnace at the heating temperature of 420-480 DEG C, keeping the temperature for 5-8min to enable the blank to be uniformly heated, and finishing dynamic recrystallization after finishing forging to obtain uniform microstructures; 3, roll forgingforming: 1) calculating a roll forging pass n; 2) roll forging forming: comprising the following steps: from (1) first-pass roll forgingforming to (4) fourth-pass roll forging forming; 4, mis-shifted forming; 5, flattening forming; 6, pre-forging forming; 7, finish forging forming: carrying out finish forging forming on the basis of pre-forging forming, designing a die according to a hot forging drawing during finish forging forming, putting a pre-forging into a mold cavity of the finish forging die, and then obtaining a part in finish forging forming under the action of a press; and 8, shaping the forging.

Description

technical field [0001] The invention relates to a forging method of a control arm, more precisely, the invention relates to a forging forming method of a triangular aluminum alloy control arm for automobiles. Background technique [0002] As an important part of the car suspension, the car control arm is used to transmit the all-directional support force required by the wheels and bear all the stress in the front and rear directions. It is an important safety part of the chassis system, which requires high strength and good reliability in the design. Its fatigue strength is directly related to the safety of vehicles and occupants. Laboratory bench testing is usually required to ensure that it meets the designed durability requirements. In this way, the appropriate test load, the number of cycles of the test and the loading method become very important to whether it can truly reflect the durability of the control arm and ensure whether it can meet the design requirements in...
