Technical field
The utility model relates to mould applications, is specifically related to I-shaped body stretching die trial.
Background technology
The batch production of a lot of products all will be by means of mould, mould of a great variety, be widely used in the shaping processing of the goods such as also metallurgical part, pottery and plastics, the precision of mould and rigidity directly have influence on the quality of product, therefore before producing in batches, will test detection.Stretching die trial is generally made up of base plate and side plate, and middle formation can have the die cavity of ad hoc structure, and is fixed to ensure its precision with the web member such as pin, bolt.In die trial, penetration concrete, plastics etc. are made test specimen, and band needs test specimen to take out from die trial after specimen molding, but the process more complicated of taking out, and waste time and energy and easily cause the damage of test specimen.
Therefore there is following problem in current stretching die trial: test specimen and die trial separation difficulty.
Utility model content
Technical problem to be solved in the utility model is how in the situation that test specimen not being separated with die trial, carries out Analysis of Concrete Tensile test.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts has been to provide the die trial of a kind of I-shaped body, comprises die body, and described die body has the die cavity of I shape, and described die body comprises:
Two half modules, described half module is surrounded and is formed by baffle plate, mould end plate and left and right mould side plate, forms upper end and one end uncovered die cavity relative with mould end plate;
Web member, formed by left and right connecting portion and horizontal part, left and right connecting portion is the U-shaped plate of opening towards die cavity outside, the two ends of described horizontal part are connected to form an entirety with the bottom of U-shaped plate respectively, the free end of described U-shaped plate extends to form forward and backward web joint along front and rear direction respectively, described forward and backward web joint is fixed with the left and right mould side plate bolt of two described half modules respectively, and described horizontal part is concordant with the end face of described baffle plate.
In the die trial of above-mentioned I-shaped body, the free end of described left and right mould side plate is respectively to the projecting inward formation protuberance of die cavity, and the side of described protuberance in die cavity is cambered surface.
In the die trial of above-mentioned I-shaped body, the lateral surface of described protuberance is provided with threaded hole, and described forward and backward web joint is provided with the through hole corresponding with described threaded hole, and bolt screws in described threaded hole two described half modules and described web member are fixed through described through hole.
In the die trial of above-mentioned I-shaped body, described threaded hole does not penetrate the medial surface of described protuberance.
The utility model, die body comprises bolted web member and two half modules, the base plate of die body and side plate integrated design, and fix with web member bolt, and the compatible degree of each several part is high, directly can fix with bolt, assembling is simple, after specimen molding, do not need extruding or mobile test specimen, only web member and two half modules need be taken apart, just can carry out Analysis of Concrete Tensile test, and can ensure the integrity of test specimen, easy and simple to handle, practical.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the web member in the utility model.
Embodiment
The utility model provides the die trial of a kind of I-shaped body, two half modules are connected and fixed and are formed a die body by web member, after specimen molding, only web member and two half modules need be taken apart, just can carry out Analysis of Concrete Tensile test, easy and simple to handle, and can ensure the integrity of test specimen.Below in conjunction with specific embodiment and Figure of description, the utility model is described in detail.
As depicted in figs. 1 and 2, the I-shaped body die trial that the utility model provides comprises two half modules 1 and web member 2, the two ends of web member 2 are bolted with the sidewall of two-half die 1 respectively, are respectively equipped with the protrusion cylinder 13 for instrument clamping die body on the outer face of two-half die 1.
Half module 1 is surrounded and is formed by baffle plate 11, mould end plate 12 and left and right mould side plate, forms upper end and one end uncovered die cavity relative with mould end plate 12.
Web member 2 is made up of left and right connecting portion and horizontal part 22, left and right connecting portion is the U-shaped plate of opening towards die cavity outside, the free end of U-shaped plate extends to form forward and backward web joint along front and rear direction respectively, and the two ends of horizontal part 22 are connected to form an entirety with the bottom of the U-shaped plate of left and right connecting portion respectively.
Baffle plate 11 is concordant with the end face of horizontal part 22, the free end of left and right mould side plate is respectively to the projecting inward formation protuberance of die cavity, the inner of protuberance is concordant with the inner face of U-shaped plate, and the side of protuberance in die cavity is cambered surface, the convenient test specimen that takes out, and the center section smooth transition of I shape, can stress concentrate merit pouring defect and affects the accuracy of test.
Two-half die 1 is arranged in the forward and backward side of web member 2, and protuberance is resisted against respectively on the lateral wall of U-shaped plate, forward and backward web joint is resisted against on the lateral wall of left and right mould side plate, the lateral surface of protuberance is provided with the threaded hole of not getting through, forward and backward web joint is provided with the through hole corresponding with threaded hole, and bolt screws in threaded hole two-half die 1 is fixing with web member 2 through through hole.
Two baffle plates 11, left and right mould side plate and horizontal parts 22 and U-shaped plate surround the die cavity of an I shape jointly.
The left and right sides indent of web member 2, makes the periphery of die body also be I shape, has also alleviated the weight of die body when saving material, is convenient to installation and removal.
On the lateral surface of half module 1 left and right sides, position relative and protuberance is provided with the bolt mounting holes of not getting through, the sidewall thickness maximum of half module 1 and web member 2 bolt junctions, because bolt needs frequent installation and removal, thicker sidewall can ensure that the rigidity of die trial is not fragile.
Learn thus, when after the specimen molding in die trial, the bolt of web member and two half modules is taken apart, just can carry out Analysis of Concrete Tensile test, and can ensure the integrity of test specimen, easy and simple to handle, practical.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
