Description

Technical Field

[0001] The utility model relates to the technical field of wheel forging, and more specifically to a forward and reverse forging device for a magnesium-aluminum alloy wheel. Background Art

[0002] The forging lines for forging magnesium-aluminum alloy wheels all adopt a unified downward or unified upward forming method. The forging dies are designed to make the material flow in one direction, so that the mechanical properties of the material are not brought into play to the optimal state and the forging performance of the material is not fully utilized. The strength of the wheel can be enhanced by manufacturing the wheel by positive and negative forging. In specific operations, the aluminum-magnesium alloy material can be placed in the pre-forging die for positive forging, and then the pre-forging is placed in the forming forging die for reverse forging to obtain the formed forging.

[0003] The shortcomings of the prior art: When the existing forging device is in use, the forging material easily sticks to the inner wall of the device during forging, so that the wheel cannot be removed well after forging, and manual disassembly is more laborious and troublesome to operate, which is not conducive to work efficiency.

[0006] Preferably, the outer mold comprises a mold body, and a slide groove and a screw groove are provided inside the mold body.

[0010] Preferably, the extrusion device comprises an extrusion hydraulic cylinder, and an extrusion hydraulic column is movably connected inside the extrusion hydraulic cylinder.

[0011] Technical effects and advantages of the utility model:

[0012] The utility model is provided with a lower die, an ejection device and a limiting column, which is conducive to demoulding of the forged wheel. By starting the motor, the stud can be rotated, the screw groove is matched with the thread, and the lower die can be moved up and down by rotating the stud in different directions, thereby driving the wheel inside it to move, so that the contact point between the wheel and the inner die can be separated, and then it is returned to its original position, and the ejection hydraulic column is controlled so that it can be extended and retracted inside the ejection hydraulic cylinder, so that the inner die can be pushed, so that the wheel can be separated from the contact point of the outer die, thereby ensuring that it can be smoothly removed, and the removal is relatively convenient without manual operation.
