Description
Technical field
The utility model relates to extrusion die fields, and in particular to a kind of for making the reverse extrusion mould of blank tubing
Tool.
Background technique
At present when reversed aluminium extruding machine squeezes outer circle 20 and arrives the aluminum round rod of outer circle 34, the fashion of extrusion used goes out two for one
Root causes the aluminum round rod ellipticity ratio extruded larger since the aluminum round rod tolerance being extruded is tighter, in addition adds front and back
Difference so that the size of aluminum round rod is often overproof, while the surface of aluminum round rod will appear burr, scrap it is more so that
The yield and yield rate of product are very low.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of reverse extrusion mold, described reversed
Extrusion die is able to solve the problem of aluminum round rod ovality and surface spikes.
According to technical solution provided by the utility model, a kind of reverse extrusion mold, the reverse extrusion mold includes squeezing
Wedge offers molding hole on the extruding seat, and the feed inlet of molding hole is located in the first end face for squeezing seat, molding hole into
A circle groove is offered in first end face at material mouth, is equipped with extrusion ring in the groove, extrusion ring surrounds to form feed opening, institute
Stating feed opening includes outer end and inner end, and the inner end of the feed opening is connected with the molding hole.
Further, the feed opening of extrusion ring includes that the first hole and the second hole and are sequentially connected from its inner end to its outer end
Three holes；A circle step is formed at first hole and the second hole connected position.
Further, the material of the extrusion ring uses wolfram steel, and ring width w is 8 ~ 10mm.
Further, the hole depth α in second hole is 2 ~ 3mm.
Further, it is 4 ~ 6 ° that the hole face in the third hole, which is the hole face taper h in conical surface third hole,.
Further, the outer end face of extrusion ring and the linear distance d squeezed between seat first end face are 1 ~ 2mm.
From the above it can be seen that the border structure provided by the utility model for solar double-glass assemblies and prior art phase
Than having following advantages: the utility model can not only improve the surface quality of pole and the ovality of outer circle, and can also
Improve production yields and yield rate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the enlarged diagram of part A in Fig. 1.
1. seat is squeezed, 110. first end faces, 111. grooves, 2. molding holes, 3. extrusion rings, 4. feed openings, 410. first holes,
420. second holes, 430. third holes, 440. steps.
Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, below in conjunction with specific embodiment, and
Referring to attached drawing, the utility model is further described.Wherein identical components are presented with like reference characters.It needs
Illustrate, word "front", "rear" used in the following description, "left", "right", "up" and "down" refer to the side in attached drawing
To.The word "inner" used and "outside" refer respectively to the direction towards or away from geometric center of specific component.
Reverse extrusion mold, as shown in Fig. 1 ~ Fig. 2, the reverse extrusion mold includes squeezing seat 1, on the extruding seat 1
Molding hole 2 is offered, offers a circle groove at the 2 feed hole edges position of molding hole for squeezing 1 first end face 110 of seat
111, extrusion ring 3 is equipped in the groove 111, the feed opening 4 of the extrusion ring 3 is connected to by its inner end with the molding hole 2,
The feed opening 4 of the extrusion ring 3 include the inner end being connected with molding hole 2 and for material enter outer end, extrusion ring 3 into
The outer end for expecting hole 4 is feed end.In order to ensure the intensity of extrusion molding dies, the material of the extrusion ring 3 uses wolfram steel, described
The ring width w of extrusion ring 3 is 8 ~ 10mm,
The feed opening 4 of extrusion ring 3 includes that the first hole 410 and the second hole 420 and are sequentially connected from its inner end to its outer end
Three holes 430；A circle step 440, the hole depth in second hole 420 are formed at 420 connected position of first hole 410 and the second hole
H is 2 ~ 3mm, and the hole depth in the second hole 420 enables to the friction of material and wolfram steel work belt when squeezing to reduce, so that molding
The surface of material is smooth, reduces burr.
The hole face in the third hole 430 is the conical surface, it is preferable that the hole face taper α in third hole 430 is 4 ~ 6 °, and hole face is cone
One end that face makes the aperture in third hole 430 be connected from 3 outer end of extrusion ring to third hole 430 with the second hole 420 is gradually reduced.
In use, material is from the middle third hole 430 that feed end enters 3 feed opening 4 of extrusion ring, the third hole 430
There are certain tapers for hole face, can slow down mass flow on the basis of compaction of the material, and then material can be evenly by the
Two holes 420 and step 440, material enters molding hole 2 after the extruding of the second hole 420 and step 440.3 feed opening 4 of extrusion ring
Structure can not only improve the surface quality of pole and the ovality of outer circle, and production yields and finished product can also be improved
Rate.
In order to ensure when squeezing, extrusion ring 3 does not crack, the outer end face of extrusion ring 3 and 1 first end face 110 of extruding seat
Between linear distance d be 1 ~ 2mm.
It should be understood by those ordinary skilled in the art that: the foregoing is merely specific embodiment of the utility model and
, it is not intended to limit the utility model, all any modifications within the purport of the utility model, made, change equivalent replacement
Into etc., it should be included within the scope of protection of this utility model.
