This invention discloses a sheet metal forming method and system based on bending springback compensation. The invention relates to the technical field of sheet metal forming. During the execution of a time-series machining path, the bending region of the sheet metal part in the current pass is acquired, and the corresponding local forming force and regional strain distribution information are marked.

This invention relates to the field of closed-die forging, specifically to a lateral extrusion pre-forging method and a final forging method. The lateral extrusion pre-forging method is applied to a pre-forging die containing an upper pre-forging die, a lower pre-forging die, and an extrusion hammer. When the pre-forging die is closed, it defines a pre-forging cavity including a feeding channel and multiple radial channels. The method includes the following steps: placing a hot billet in the feeding channel of the pre-forging die; after die closure, driving the extrusion hammer perpendicular to the die-closing direction to extrude the hot billet, while simultaneously applying a lateral support force in the opposite direction to balance the extrusion force, thereby forcing the billet to flow from the feeding channel to each radial branch until it fills the cavity; and after holding the pressure, sequentially removing the extrusion force, lateral support force, and die-closing force. This invention uses a lateral extrusion hammer to extrude a hot billet in a closed pre-forging cavity, allowing it to flow within closed radial channels. This results in less flash, reducing material waste, and requires lower extrusion forming force, thus reducing production costs.

A composite forming process for semi-solid extrusion and forging of fuel hydrant manhole covers induced by cold pressing of aluminum alloy chips is proposed. First, the dimensions of the cold-pressed aluminum alloy disc required for forming the manhole cover are designed. Then, ZL104 aluminum alloy chips are cold-pressed into the disc shape, and the disc is heated and held at a specific temperature to obtain a semi-solid fine spherulitic material. Next, the obtained semi-solid fine spherulitic material is rapidly placed into a U-shaped cavity formed by the outer and lower molds. The upper mold is pressed down, driving the precision forging mold to achieve rough extrusion deformation of the semi-solid fine spherulitic material and hold the pressure, thus forming a rough-extruded semi-solid fuel hydrant manhole cover. Then, while maintaining the pressure of the upper mold, the precision forging mold is controlled to forge the rough-extruded semi-solid fuel hydrant manhole cover, ultimately obtaining a fuel hydrant manhole cover part possessing both a semi-solid spherulitic structure and a forged deformed structure. This invention features a simple process, low forming force, high material utilization, high product density, and good mechanical properties.

This invention relates to the field of closed-die forging, specifically to a lateral extrusion pre-forging die, a final forging die, and a forging system. The lateral extrusion pre-forging die includes: an upper pre-forging die and a lower pre-forging die that move along the die-closing direction, and an extrusion hammer that moves perpendicular to that direction.

This invention uses a lateral extrusion hammer to extrude hot billets within a closed pre-forging cavity, allowing them to flow within the closed radial channels. This results in less flash, reducing material waste, and requires lower extrusion forming force, thus reducing production costs.
