Abstract
The utility model discloses a kind of asphalt marshal pieces to hit practical die trial; mainly it is made of die trial pedestal, bolt, outer circle ring cylinder and four part of inner circle ring cylinder; the inner circle ring cylinder is made of four groups of circular arc steel discs; the outer circle ring cylinder is provided with threaded hole; and entirety is formed by rivet interlacement with inner circle ring cylinder through threaded hole by bolt; can be used when Marshall standard specimen makes artificial stripping instead of ingot stripper work using the utility model; with cost economic, it is easy to operate the features such as.
Description
Technical field
The utility model belongs to die trial technical field of mold, and in particular to a kind of asphalt marshal piece hits practicality
Die trial.
Background technology
Marshall Test is one of important tests of designing asphalt mixture, by detecting the indexs such as its density, porosity
To determine the significant designs such as bitumen aggregate ratio proportioning, marshal piece Forming Quality will directly affect result of the test and follow-up pitch mixes
Close material proportioning.Asphalt marshal piece hit practical die trial be using compacting process make bitumen mixture specimen when into
The mold of type, current specifications《Highway engineering pitch and Asphalt Mixture Experiment regulation》Required standard is tried in (JTG E20-2011)
Mould circular ring type die trial made of high-carbon steel or tool steel, simple in structure, low cost, but make marshal piece according to specification
Die trial need to be placed baking oven preheating by flow first, and test specimen hits after reality and needs to read bitumen mixture specimen height, also finally
Special ejector need to be used to carry out the test specimen demoulding.Easily because of test specimen when being demoulded in actual tests operation to marshal piece
Centering misoperation causes test specimen side wall mass loss, and follow-up test data is caused to generate large error, examination can be squeezed when serious
Part and be deformed, test specimen is caused to be scrapped completely, and operate it is extremely inconvenient, when carrying out the test specimen demoulding using stripper, each
Test specimen demoulding time averagely needs 2min-3min, takes time and effort.Therefore, developed again for code requirement mold Shortcomings
Easy to operate, conveniently stripped standard impact density die trial is very necessary.
Utility model content
The purpose of this utility model is that for deficiency existing for existing mold, a kind of asphalt Marshall examination is provided
Part hits practical die trial, can be relied on using die trial shaping marshal piece and manually be demoulded, easy to operate and ensure test specimen
It is not deformed completely.
For achieving the above object, the present invention adopts the following technical scheme that:
Asphalt marshal piece hits practical die trial, mainly by die trial pedestal, bolt, outer circle ring cylinder and interior annular
Cylinder forms;Outer circle ring cylinder is equipped with 4 threaded holes;Inner circle ring cylinder is combined into entirety by bolt and outer circle ring cylinder.
Inner circle ring cylinder is made of 4 circular arc steel discs, and circular arc steel disc both sides of the edge are respectively equipped with tenon, and circular arc steel disc can lead to
Cross tenon mechanical connection.
The bolt is internally provided with rivet arrangement.
Bolt is equipped with locating piece, and when inwardly tightening bolt to locating piece contact outer circle ring cylinder, 4 groups of circular arc steel discs are combined into
Inner circle ring cylinder.
Compared with the prior art, the advantage of the utility model is:
The die trial generates torsion by inner circle ring cylinder separated demolding by bolt and outer circle ring cylinder, does not utilize stripper
The test specimen demoulding is carried out, uses manpower and material resources sparingly, and ensures that test specimen is not deformed completely.

Specific embodiment
With reference to embodiments and its attached drawing is further non-limitingly described in detail technical solutions of the utility model.
First, asphalt marshal piece hits the basic structure of practical die trial:
As shown in Figure 1, Figure 2 with shown in Fig. 3, a kind of asphalt marshal piece hits practical die trial, mainly by die trial pedestal
8th, bolt 1, outer circle ring cylinder 3 and inner circle ring cylinder 4 form;The outer circle ring cylinder 3 is equipped with 4 threaded holes 2;The interior annular
Cylinder 4 is combined integral by bolt 1 with outer circle ring cylinder 3;The inner circle ring cylinder 4 is made of 4 circular arc steel discs, Circular Steel
Piece both sides of the edge are respectively equipped with tenon 6, and arc tube physical efficiency is mechanically connected by tenon 6;The bolt 1 is internally provided with 5 knot of rivet
Structure;The bolt 1 is equipped with locating piece 7, when inwardly tightening bolt 1 to the contact outer circle ring cylinder 3 of locating piece 7,4 groups of circular arc cylinder groups
Synthesize inner circle ring cylinder 4.
2nd, asphalt marshal piece hits the application method of practical die trial:
1st, four groups of bolts 1 are inwardly tightened by threaded hole 2, it is interior at this time when being screwed onto locating piece 7 and being contacted with outer circle ring cylinder 3
Annulus cylinder 4 is mechanically connected by tenon 6, and inner circle ring cylinder is positioned on die trial pedestal 8.
2nd, it will uniformly insert in die trial after mixture mix, and hit after being consolidated with slotting tool using compaction test apparatus progress is two-sided
It is real.
3rd, test specimen is hit after real be cooled to room temperature (no less than 12h), outwards loosers a bolt 1 by the generation torsion of outer circle ring cylinder 3
Four groups of annulus steel discs are separated by power, and shaping marshal piece is taken out.
