Description
Technical field
The present invention relates to aluminium Baogang continuously extruding and molding Tool and Die Technology, be specifically related to a kind of aluminium Baogang continuous extruder die cavity recombination region size adjustment structure.
Background technology
The basic structure of continuous extruder comprises the squeegee roller with concave channels, and it is by power transmission shaft driven rotary; Press shoe, it is fixed structure, and the part contacted with squeegee roller is sealing groove block, and play the effect of sealing extrusion wheel concave channels, forming a cross section is square extrusion chamber; Be fixed on the plug of the extrusion chamber port of export, the extrusion chamber port of export is sealed, force metal can only flow out from extrusion die; Extrusion die, or be arranged on plug, tangentially extrude, or be arranged in press shoe, radial compression.Operationally, two aluminium bars are simultaneously by the race of gear drive feeding roller feeding annular extrusion wheel, and when squeegee roller rotates, aluminium bar is brought in the gap of race and die cavity for aluminium Baogang continuous extruder.Because aluminium bar is extruded between race and die cavity, very large pressure is created in aluminium bar inside, these extruding energy parts are with Thermal release, temperature raises and makes aluminium bar be enough to produce extensional, stretching force forces aluminium bar to enter die cavity recombination region by the through hole in die cavity, when steel core is admitted to die cavity recombination region simultaneously, heat melt aluminium and steel core extrude cohere shaping.
Whether the size of die cavity recombination region is reasonable will directly have influence on the quality of product, die cavity recombination region is too little, the product composite quality of production can be made poor, some part meets thickness and piles up, cause larger flash, and because in born chamber, dynamic pressure is little, steel core and hot adhesion of melting aluminium can be affected.The size of die cavity recombination region is too large, due to steel core expose too many, and in chamber, dynamic pressure is too large, when tension force increases, likely causes steel core to rupture.
Summary of the invention
The invention is intended to the aluminium Baogang continuous extruder die cavity recombination region size adjustment structure that a kind of adjustable die cavity recombination region size is provided.
Aluminium Baogang continuous extruder die cavity recombination region size adjustment structure in this programme, comprise squeegee roller, be positioned at plug and the mold of squeegee roller periphery, it is the conveying extrusion chamber of aluminium bar between the ditch connected in star of squeegee roller and plug, die cavity is formed between plug and mold, plug has the via hole be communicated with die cavity recombination region, extrusion die is provided with in described die cavity, with it is characterized in that, also comprise and be arranged on guiding module in die cavity and adjusting nut, it is die cavity recombination region between guiding module and extrusion die, the mould intracavity wall being positioned at guiding module side has the first shoulder block, end face and described first shoulder block of adjusting nut offset, the cylindrical of adjusting nut and mould intracavity wall are fitted, adjusting nut is threaded with described guiding module, described die cavity is stretched out in the end of adjusting nut.
The solution of the present invention, the axial location of guiding module in die cavity is regulated by rotating adjusting nut, and then the size of die cavity recombination region between adjustable guiding module and extrusion die, thus when extruded, adjust the die cavity recombination region meeting Forming Quality and require.
Further, the outer surface of guiding module near extrusion die side is the conical surface.The outer surface of guiding module makes the conical surface, can increase the size of die cavity recombination region.
Further, extrusion die is by having extrusion chamber, and the point diameter of extrusion chamber is suitable with aluminium Baogang bus diameter size, and extrusion chamber has enlarging backward.The front end of extrusion chamber is used for the extruding that heat melts aluminium and steel core and coheres, and enlarging is made in extrusion chamber rear end, can not have an impact to the surface of the aluminium Baogang bus after shaping.
Further, be also provided with the mount pad of ring-type in die cavity, the mould intracavity wall being positioned at extrusion die side has the second shoulder block, and end face and second shoulder block of mount pad offset, and mount pad and the second shoulder block are fixed by straight pin, and extrusion die is fixed on mount pad.Install extrusion die by mount pad, extrusion die is installed more firm, and extrusion die can not produce axial float.
