Abstract
The utility model relates to a special clamping apparatus for tension test of thickness direction; which comprises a pair of clamps, each of which is provided with a clamp sleeve. One end of the clamp sleeve is provided with a groove (4), while the middle of the other end is provided with a clamping bar (5). When drawing close, the two clamp sleeves are movably connected by two guide rods (2) with symmetrical distribution, meanwhile a sample chamber in agreement with the shape of a sample (6) is formed by the groove (4). The utility model has the advantages of high work efficiency, easy extension, simple manipulation, and economizing labor. Furthermore, the whole test can be accomplished by only one person.
Description
Technical field
The utility model relates to a kind of thickness direction (Z to) tensile test unit clamp.
Background technology
Steel plate thickness direction tensile test section length growth rate is an important performance indexes of the high-performance deck of boat, construction(al)steel.When carrying out this test, need to carry out tension test, measure its reduction of area after the sample fracture in sample through thickness direction.For the steel plate of sample thickness,, be prepared into the two ends welding tensile sample (see figure 3) of GB/T228-2002 " tension test of metal material normal temperature " regulation by operations such as sawing one car clamping rod one welding clamping rod and test block one machined into less than 40mm.For the steel plate of thickness greater than 40mm, a kind of is to adopt to be processed into standard sample with upper type, and a kind of is by sawing one machined into, is prepared into not welded specimen (seeing Fig. 4 and Fig. 5) of two ends.
The two ends welding tensile sample manufacturing procedure time is long aborning at present, therefore adopts not welded specimen of two ends, can shorten process time, cuts down finished cost, and enhances productivity.But, because be that the welded specimen retaining part is very not short at two ends, can not directly clamping on the fixture block of cupping machine, must adopt the circular sleeve unit clamp to test.But, when adopting the circular sleeve unit clamp to test, after placing on the anchor clamps, must have a people two hands before test to buttress the position up and down of specimen holder respectively on sample, treat that whole anchor clamps and sample are stressed after, can decontrol.Whole process can only be carried out the test of a sample, when on-test, does not need testing crew to fix before upper and lower anchor clamps and sample are stressed, clamping sample manipulation complexity, and length consuming time, needing 2 people's testing crews to cooperate can test.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of thickness direction (Z to) tensile test unit clamp, so that change existing clamping sample mode.These anchor clamps can make things convenient for clamping, shorten the clamping sample time, reduce operating personnel, increase work efficiency.
The technical scheme that its technical matters that solves the utility model adopts is: be provided with a pair of anchor clamps, each anchor clamps is provided with the anchor clamps cover, and an end of anchor clamps cover has groove, and other end end face middle part is provided with supporting rod; When two anchor clamps covers are drawn close, it is movably connected by two guide poles that are symmetrically distributed, and its groove formation sample placing storehouse, the shape of this placing storehouse and sample matches.
The utlity model has following major advantage:
One. can disposablely measure 3 samples simultaneously, work efficiency has improved 2 times, and is simultaneously simple to operate, do not need people's fixing upper and lower anchor clamps when on-test, only needs 1 people can finish Total Test.1 of minimizing personnel.
They are two years old. market outlook prediction: because steel plate thickness direction pulling force characteristic is the important performance indexes that skyscraper steel, Important Project are used steel and hull steel etc., it is domestic and international each physical and chemical inspection chamber routine inspection project, therefore, these anchor clamps will have great application value in each laboratory.

Embodiment
Structure of the present utility model such as Fig. 1, Fig. 2 and shown in Figure 6: be provided with a pair of anchor clamps, each anchor clamps is provided with the anchor clamps cover, and promptly left anchor clamps are provided with left anchor clamps cover 1, and right anchor clamps are provided with right anchor clamps cover 3; One end of each anchor clamps cover has groove 4, and other end end face middle part is provided with supporting rod 5.When left anchor clamps cover 1 and right anchor clamps cover 3 were drawn close, they were movably connected by two guide poles 2 that are symmetrically distributed, and its groove 4 constitutes sample placing storehouse, and the shape of this placing storehouse and sample 6 matches.
In left anchor clamps cover 1 and right anchor clamps cover 3, its groove 4 all can radially run through, and the width of this groove is 18～25mm, can put into three samples 6 simultaneously by its sample placing storehouse that constitutes like this; Or decide according to actual needs.
Described supporting rod 5, its diameter are 28～32mm; Perhaps decide according to actual needs.This supporting rod is convenient to clamp in cupping machine.
The course of work of the present utility model is: the supporting rod 5 of being clamped left anchor clamps and right anchor clamps by two V-type jaws of cupping machine respectively; When for example left jaw of certain jaw of cupping machine moves, two anchor clamps are slowly separated, this moment, the effect of guide pole 2 was that its anchor clamps overlapped only axially-movable when left and right sides anchor clamps were separated, and did not laterally rotate and was shifted, and guaranteed that sample 6 only is subjected to longitudinal pulling force.Such three samples 6 can be subjected to longitudinal stretching power to straight fracture.After the stressed fracture, take out sample, measure the reduction of area of having no progeny, draw the performance number of three tests.
