摘要： A process operating a forging mold for manufacturing a towing bar involves having a softened aluminum material after preheating in a mold; the mold contains a molding cavity; one end of the cavity is provided with a contour of a gooseneck of the towing bar and another end is provided with a contour of a middle section of a shank of the towing bar; the mode is then incorporated with an extension mold containing an extension hole for molding an extended section of the shank of the towing bar; a punch performs forging process on the aluminum material in the cavity externally from the extension hole; and the aluminum material is extruded by the punch to extend for a preset length in the direction towards the extension mold to complete the molding of the towing bar.

摘要： A method for forging/molding a coarse blank of an aluminum transmission shaft, including steps of: placing burn-in softened aluminum material into a preheated mold; using a first punch head to first forge the aluminum material in the mold cavity from outer side of the molding hole so as to form a blank body of the transmission shaft with two pivot heads wherein one pivot head is located at each end of the transmission shaft and a shorter middle shaft rod; moving out the first punch head and connecting an extension mold with the mold; and immediately using a second punch head to secondarily forge the blank body in the mold cavity from outer side of the extension hole so as to make an end section of the second punch head extend into the mold cavity to a position near the inner end of the mold cavity, whereby the middle shaft rod of the blank body outward axially extends to the extension mold into a predetermined length to form the transmission shaft.

摘要： A method for forging/molding a coarse blank of an oil cylinder, including steps of: placing burn-in softened aluminum material into a preheated mold; using a first punch head to first forge the aluminum material in the mold cavity from outer side of the molding hole so as to form a blank body of the oil cylinder with a first end cap, a second end cap and a shorter cylinder body; moving out the first punch head and connecting an extension mold with the mold; and immediately using a second punch head to secondarily forge the blank body in the mold cavity from outer side of the extension hole and making the end section of the second punch head extend into the mold cavity to a position near the inner end of the mold cavity, whereby the cylinder body of the blank body outward axially extends to the extension mold into a predetermined length so as to form the oil cylinder.

摘要翻译： 一种用于锻造/模制油缸的粗坯的方法，包括以下步骤：将煅烧的软化铝材料放入预热的模具中; 使用第一冲头首先从模制孔的外侧锻造模腔中的铝材料，以形成具有第一端盖，第二端盖和较短缸体的油缸的坯体; 移出第一个冲头并将延伸模与模具相连; 并且立即使用第二冲头从第二冲头的外侧二次锻造模腔中的坯体，并使第二冲头的端部延伸到模腔中至靠近模腔内端的位置 由此，坯体的筒体向外轴向延伸到延伸模具预定长度以形成油缸。
