Abstract
The invention relates to a core column production method, a special machining device for a core column and a forming die column for the core column. The core column production method includes: mounting roll-forming die columns on a rolling machine to bend a steel strip into a cylindrical core column; and seaming butt-welded side seams on the side wall of the core column by the aid of a seaming device to produce a needed finished core column. When in use, forming rollers for extruding the steel strip can be the same in structure, and a forming channel between each forming roller and each roll-forming die column can gradually wrap the periphery of the roll-forming die column along the feed direction of the steel strip only by adjusting the distance between each forming roller and each roll-forming die column, so that the rolling machine can be an existing rolling machine, and the core column can be produced only by additionally mounting the roll-forming die columns on the forming rollers of the rolling machine. Further, dependence on production equipment during production of the core column is avoided, and the production cost of the core column is reduced.
Description
Technical field
The present invention relates to the stem stem field shaping technique, relate in particular to a kind of production method of stem stem, also relate to the shaping mould post that uses in special apparatus for working and this processing unit (plant) of production method of this stem stem simultaneously.
Background technology
At present, the stem stem section bar adopts the method for casting to process more, just earlier melt metal aluminium is cast in the mould of stem stem section bar; And then with the cast member of the stem stem section bar of moulding through production technologies such as extrusion modling, surface treatments, could finally obtain stem stem section bar product, thereby when adopting traditional production method to produce the stem stem section bar; The complex procedures of production process makes the production control difficulty of stem stem strengthen lengthening consuming time; And because when adopting traditional production method to produce the stem stem section bar; The resources of production that need expend are more, thereby the production cost that makes the stem stem section bar produce strengthens, and the whole cost of stem stem section bar improves.
Application number is moulding and the welding procedure that 200910085560.0 Chinese invention patent discloses a kind of closed-end cold-bent section steel; This forming process sets gradually the molded running roller of the different upper and lower roll of structure through the direction of feed along steel band steel band is pushed; Thereby the stem stem workpiece that steel band is squeezed into have butt-welded side seam on the sidewall; Through the method for welding this butt-welded side seam is sewed up then; But because in the process of the stem stem workpiece that steel band is squeezed into tubular, the shape and structure of each moulding running roller on the roll squeezer has nothing in common with each other, thereby this production technology is high to the requirement of roll squeezer; Need special roll squeezer that this production method is achieved, make the production cost of closed-end cold-bent section steel improve.
