Abstract
The invention belongs to the field of aluminum extrusion sectional bars, and particularly relates to a dense hollow sectional bar and a manufacturing method of the dense hollow sectional bar. The dense hollow sectional bar comprises at least two sectional bar single bodies which are stacked in the vertical direction, each sectional bar single body is of a plate-shaped structure, protruding meshing parts are arranged on the upper face and the lower face of the each sectional bar single body, and at least two meshing parts at a certain interval are arranged on each face of each sectional bar single body. Each meshing part is composed of at least two tooth-shaped protrusions, and a groove formed between every two tooth-shaped protrusions, and the corresponding meshing parts of every two adjacent sectional bar single bodies are closely meshed into a whole without seams through the tooth-shaped protrusions and the grooves in a punching mode. Only a plurality of same-structure single bodies without hollow structures are formed in an extrusion mode, the single bodies are meshed and then combined together through punching riveting, then a plurality of products of hollow structures can be formed, and the method has the advantages of being low in manufacturing cost and high in reliability, practicability and operability.
Description
Technical field
The invention belongs to Al squeezing material field, relate in particular to a kind of intensive hollow profile, also relate to its preparation method.
Background technique
The single crowded type technique that compares, obtain multiple hollow-core constructions has very large difficulty concerning aluminium extruded mould.Industry general technology obtains hollow being easier to, and multiple hollow-core constructions have very large technical limitations concerning aluminium extruded mould, the size restrictions of hollow-core construction, die space restriction.And die cost is high, the life-span is short, easily burst-mode.
The single stamping process that compares, obtains by mould the product that bending fastens, and has multiple hollow-core constructions.But precision and technical requirements to mould are higher, and fabricating cost and maintenance cost are high.Be exactly the thick restriction of material piece of punching press in addition, thicker material is very large to the power that applies of punching press, and the overall dimensions of mould is very large, and cost is very high.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of intensive hollow profile with and preparation method thereof, have that fabricating cost is low, reliability is strong, practicability and the advantage such as workable.
Technical problem to be solved by this invention is achieved by the following technical programs:
A kind of intensive hollow profile, comprise at least two section bar monomers of stack up and down, described section bar monomer is platy structure, and upper and lower surface arranges bossed bite, and the corresponding bite in neighbouring two section bar monomer positions is integrated through the tight seamless interlock of punching press.
Further, every one side of described section bar monomer has the be separated by bite of a segment distance of two places at least.
Further, described bite distributes at the two ends, left and right of the every one side of section bar monomer.
Further, described bite is at least two dentations, between two dentations, forms groove, and adjacent bite corresponding to two section bar monomers is integrated by dentation and engagement.
Preferably, the width of the bottom of described dentation is slightly narrower than other position.
Preferably, described intensive hollow profile is aluminium section bar.
The preparation method of above-described intensive hollow profile, preparation process comprises:
(1) obtain above-described section bar monomer by squeezing type technique;
(2) spliced the section bar monomer of requirement by bite interlock;
(3) section bar monomer interlock having been spliced is put press work platform, punching equipment is implemented stamping press to the assembly parts of multiple section bar monomers, the pressurized deformation of dentation top, clamp-ons the slightly wide space of bottom portion of groove, and mutual interlock between section bar monomer is tightened together.
The present invention has following beneficial effect:
The present invention only need to squeeze type and go out the monomer of some same structures without hollow-core construction, after interlock, again by punch riveting together, forms the product of multiple hollow-core constructions, has that fabricating cost is low, reliability is strong, practicability and the advantage such as workable.

Embodiment
Below in conjunction with accompanying drawing 1-6 and embodiment, the present invention will be described in detail.
A kind of intensive hollow profile, described intensive hollow profile is aluminium section bar.Comprise at least two section bar monomers 1 of stack up and down, described section bar monomer 1 is platy structure, upper and lower surface arranges bossed bite 11, every one side of described section bar monomer 1 has the be separated by bite of a segment distance of two places at least, bite distributes at the two ends, left and right of section bar monomer 1 every one side, described bite is at least two dentations 111, between two dentations, form groove 112, two adjacent section bar monomers are integrated neighbouring two seamless interlocks of section bar monomer 1 by dentation 111 and the groove 112 of corresponding bite through punching press.The width of the bottom of described dentation 111 is slightly narrower than other position.
The preparation method of intensive hollow profile as above by step is:
First: obtain by squeezing type technique the section bar monomer 1 that is platy structure, described section bar monomer 1, upper and lower surface arranges bossed bite 11, be distributed in the two ends, left and right of section bar monomer 1, described bite is that the groove 112 forming between at least two dentations 111 and two dentations forms, the width of the bottom of dentation 111 is slightly narrower than other position, and two adjacent section bar monomers are integrated neighbouring two section bar monomer 1 interlocks by dentation 111 and the groove 112 of corresponding bite;
Then: the section bar monomer 1 of requirement has been spliced in dentation 111 and groove 112 interlocks by bite 11;
And then: the section bar monomer 1 that interlock has been spliced is put press work platform, punching equipment is implemented stamping press to the assembly parts of multiple section bar monomers 1, dentation 111 top pressurized deformation, clamp-on groove 112 bottoms and be slightly wider than the space of opening, make between section bar monomer 1 interlock mutually tighten together;
Last: section bar monomer 1 periphery that mutual interlock is tightened together is carried out smooth processing.Smooth processing is according to concrete condition, selects conventional cutting, and the means such as polishing are processed.
