Problems solved by technology

[0002] Existing high-precision forgings for truck hubs usually use a heavy-duty straight forging machine. The oil cylinder drives the mold to run vertically, and the mold presses the rough billet downwards. The disadvantages are: low production efficiency, large volume of forging press, high energy consumption, low forging precision, large consumption of metal, and high production cost

Embodiment Construction

[0016] The invention relates to a method for processing high-precision forgings of truck wheel hubs by rotary forging, such as figure 1 — Figure 4 As shown, it is characterized by:

[0017] ①, aluminum rod heating, take aluminum rod 1, use the aluminum rod heating furnace to heat the aluminum rod for 3 hours, and heat it to 420°C-480°C;

[0018] ② For upsetting the aluminum rod, take the oil press, which is equipped with the upper die pressing plate 2 and the lower die pressing plate (3), the preset height of the upper die pressing plate is 150 mm, and the pressure is 2000 tons, and the heated aluminum rod is molded and upset Get rough billet 4;

[0019] ③, turn forging, take the rough billet 4 and put it in the turn forging machine, the turn forging machine includes the first upper die holder 5 and the first lower die holder 6, the first upper die is installed under the first upper die holder 8. The first upper die base 5 and the first upper die 8 pass through the upper d...

Abstract

The invention relates to a processing method of carrying out rotary forging on forge pieces with high precision of a truck hub. The processing method is characterized by comprising the following steps of (1) heating an aluminium bar: taking the aluminium bar, adopting an aluminium bar heating furnace to heat the aluminium bar for 3 hours, and heating to be 420 DEG C-480 DEG C; (2) upsetting the aluminium bar: taking an oil press, arranging an upper moulded board and a lower moulded board in the oil press, presetting the height of the upper moulded board to be 150mm and the pressure of the upper moulded board to be 2,000 tons, and mould-pressing and upsetting the heat aluminium bar so as to obtain a rough blank; (3) rotary forging: putting the rough blank in a rotary forging machine, contacting the rough blank and a first upper mould line, and gradually mould-pressing to form a workblank; (4) ejecting the workblank: after the rotary forging machine descends to open a mould, ascending a first ejection rod to eject the workblank; (5) punching and chambering: grabbing the ejected workblank into a punching and chambering forging machine through a manipulator, punching and chambering the workblank through the punching and chambering forging machine, and obtaining the forge pieces with high precision.

Description

technical field [0001] The invention relates to a processing method for a high-precision forging of a forged truck hub, in particular to a processing method for a high-precision forging of a rotary forged truck hub. Background technique [0002] Existing high-precision forgings for truck hubs usually use a heavy-duty straight forging machine. The oil cylinder drives the mold to run vertically, and the mold presses the rough billet downwards. The disadvantages are: low production efficiency, large volume of forging press, high energy consumption, low forging precision, large consumption of metal, and high production cost. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a rotary forging truck with small volume, good rigidity, high precision, reduced metal consumption, simple mold structure, easy manufacture, convenient installation, and reduced production costs The processing method of the ...
