摘要： A method is used to manufacture a tube having a hollow interior for housing an axle shaft. The tube is formed in a single machine having a fixed base and a single press structure movable toward the fixed base. The single machine includes first and second die assemblies coupled to the fixed base and first and second mandrels coupled to the single press structure. The method includes the steps of placing a billet into the first die assembly, pressing the billet into the first die assembly with the first mandrel to producing a pre-formed billet, and moving the pre-formed billet from the first die assembly to the second die assembly. THE method further includes the steps of pressing the pre-formed billet into the second die assembly with the second mandrel to elongate the pre-formed billet and form a hollow interior therein to produce an extruded tube.

摘要： A method is used to manufacture a drawn tube having a hollow low interior for housing an axle shaft. The method includes the steps of placing a billet into a first die assembly and pressing the billet into the first die to producing a pre-formed billet. The method also includes the steps of moving the pre-formed billet from the first die assembly to a second die assembly and pressing the pre-formed billet into the second die assembly to produce an extruded tube. The method further includes the steps of moving the extruded tube from the second die assembly to a third die assembly and pressing the extruded tube into the third die assembly to further elongate the extruded tube and decrease the thickness of the wall of the extruded tube to of from about 3 to about 18 millimeters to produce the drawn tube having the yield strength of at least 750 MPa.

摘要： A method for manufacturing a bicycle front fork having a wheel clamping base. The method includes the steps of extruding an aluminum alloy substrate having three rectangular bars, wherein the two of the rectangular bars have assembling segments; cutting the substrate for a blank and placing it into a mold for forging the three rectangular bars into three round bars; placing the blank into another mold for extruding and punching the three round bars to have guide holes; drilling the round bars along the guide holes to form three round tubes; flattening and shrinking openings of two of the three round tubes; molding the assembling segments; downwardly bending the two round tubes having the assembling segments into two fork tubes of a bicycle front fork; punching the assembling segments into locking connection portions for a clamping base of the bicycle front fork.

摘要： A method for manufacturing an integrated aluminum alloy bicycle front fork is revealed. Aluminum alloy is extruded to form substrate having three rectangular bars. Cut the substrate to get a blank. The blank is set into a mold for forging the three rectangular bars into three round bars. Then burr and waste material are removed. Next the blank is set into another mold for extruding the three round bars and the three round bars are punched to have guide holes. The round bars are drilled along the guide holes and penetrated to form round tubes. A tube opening of two round tubes is flattened and narrowed. Then the two round tubes are bent downward to form fork tubes of a front fork. The rest tube forms a front fork stem. Thereby an integrated light weighted front fork with good structural strength and beautiful appearance is produced.

摘要： An aluminum seat of a heat sink is made by placing a fixed amount of aluminum material into a forming slot of a lower die to undergo one-time extrusion by a punch of an upper die. A plurality of indentations are longitudinally disposed on an interior wall of the forming slot of the lower die, and the bottom of the forming slot is a closed end. When the fixed amount of aluminum material is distributed over the forming slot and the indentations during the extrusion, corresponding ribs are formed on an exterior wall of the aluminum seat of the heat sink after the dies are drawn off. Each rib facilitates firm insertion of fin units into the seat. The heat sink with radial fin units is produced from the aluminum seat and the fin units.
摘要翻译：通过将固定量的铝材料放置在下模的成形槽中来制造散热器的铝座，以通过上模的冲头进行一次挤压。多个凹口纵向设置在下模的成形槽的内壁上，并且成形槽的底部是封闭端。当固定量的铝材料分布在成形槽上时和在挤出过程中的压痕时，在模具被拉出之后，在散热器的铝座的外壁上形成相应的肋。每个肋有助于将翅片单元牢固地插入到座中。具有径向翅片单元的散热器由铝合金座和翅片单元制成。
