Specific embodiment
It is as follows that the present invention is described further with reference to the accompanying drawings and examples:
A kind of Gleeble loading tool being less than graphite flake and tantalum piece radius suitable for radius of specimen as shown in Figure 1, Figure 2 and is schemed
Shown in 3, including two handgrips 1, the handgrip 1 include clamping part 11, interconnecting piece 12 and hand-held part 13, described 12 one end of interconnecting piece
It is connect with hand-held part 13, the other end is connect with clamping part 11；
Semicircle through slot 111 is equipped on the clamping part 11, the semicircle on the interconnecting piece 12 of described two handgrips 1 is logical
Slot 111 is open surrounds sample mounting hole relatively；Semicircular first step slot 112 and second is equipped at the both ends of clamping part 11
Step groove 113；The first step slot 112 and second step slot 113 and through slot 111 are coaxial, and, the half of first step slot 112
Diameter is greater than the radius of through slot 111, and the radius of second step slot 113 is more than or equal to the radius of first step slot 112；Described two
First step slot 112 on the interconnecting piece 12 of a handgrip 1 is open surrounds tantalum piece mounting hole relatively；The connection of described two handgrips 1
Second step slot 113 in portion 12 is open surrounds graphite flake mounting hole relatively；The tantalum piece mounting hole and graphite flake mounting hole with
Sample mounting hole is connected；And tantalum piece mounting hole is between graphite flake mounting hole and sample mounting hole；It is set on clamping part 11
There is the thermocouple groove 114 being circumferentially arranged along clamping part 11, the thermocouple groove 114 is radial along sample mounting hole by sample mounting hole
Through the outer surface of clamping part 11；
The interconnecting piece 12 of described two handgrips 1 is flexibly connected, and is equipped with clamping two between the interconnecting piece 12 of two handgrips 1
The Fastener 5 of a handgrip 1.
In use, firstly, thermocouple to be circumferentially welded on to 2 middle part of sample along sample 2；Then, holding hand-held part 13 makes it
In a handgrip 1 upper, another handgrip 1 is under.It exerts a force to hand-held part 13, opens the clamping part 11 of two handgrips 1, by band
There is the sample 2 of thermocouple to be placed in the through slot 111 of lower handgrip 1；Tantalum piece 3 is placed in the first step slot in lower handgrip 1
In 112；Graphite flake 4 is placed in the second step slot 113 of lower handgrip 1；Unclamp hand-held part 13, make upper handgrip 1 with
It is close together in the handgrip 1 under, the two pieces pressure head of Gleeble is made to be distributed the graphite flake installation at insertion sample mounting hole both ends
Hole, it is opposite to abut against graphite flake 4, thus, graphite flake 4, tantalum piece 3 and sample 2 are clamped between two pieces pressure head；Finally, right again
Hand-held part 13 exerts a force, and two handgrips 1 are laid down from sample 2.Sample 2 is avoided to contact pressure head, in test, the half of sample 2
Diameter is less than the radius of graphite flake 4 and tantalum piece 3, therefore, the radius of first step slot 112 is greater than the radius of through slot 111, second step slot
113 radius is more than or equal to the radius of first step slot 112.And want that pressure head can be made to be capable of fixing sample 2, therefore, it is making
When making, the length of sample 2 is larger than sample mounting hole, it is so-called slightly larger than pressure head opposing compression is able to satisfy when, sample 2 can be by
To from axial pressure.
A kind of Gleeble loading tool being less than graphite flake and tantalum piece radius suitable for radius of specimen, due to First
Rank slot 112 and second step slot 113 and through slot 111 are coaxial, therefore, sample 2, pressure head, tantalum piece 3 and graphite flake 4 position obtain really
It is fixed, facilitate loading, it is easy to make 4 centering of sample 2, tantalum piece 3 and graphite flake, can effectively avoid sample 2 and pressure head from bonding, tantalum piece 3
The phenomenon that contacting with pressure head is conducive to the accuracy for improving test；Also, when due to loading, thermocouple is located at thermocouple groove 114
In, thermocouple groove 114 plays a protective role to thermocouple, avoids external object collision thermocouple, thermocouple is caused to fracture.
From above embodiment: the interconnecting piece 12 of two handgrips 1 is flexibly connected；That is, interconnecting piece 12 can pass through conjunction
The connection such as page.Herein, it is preferred that be respectively equipped with attachment base 121 at the both ends of interconnecting piece 12, be equipped on attachment base 121 with
The shaft 6 that two handgrips 1 are rotatably assorted.
In the above-described embodiment, Fastener 5 can be bolt, by bolt by the interconnecting piece 12 of two handgrips 1 conjunction
Together.But this kind of mode using when need demounting bolt, in loading, need two people's compounding practices, a people holds handgrip
1, another people installs or demounting bolt.Fastener 5 or compressed spring, compressed spring one end and one of handgrip 1
Interconnecting piece 12 be connected, the other end is connected with the interconnecting piece 12 of another handgrip 1, still, compressed spring install inconvenience.It is preferred that
, the Fastener 5 is torsionspring, and the torsionspring is set in shaft 6.Torsionspring is easy for installation, is directly set with
In in shaft 6.
For the ease of manufacturing, it is preferred that the structure of described two handgrips 1 is identical.The structure of two handgrips 1 is identical,
In the molding or processing of handgrip 1, it is only necessary to carry out primary parameter setting to process equipment；In assembling, it is not necessary to which differentiation is grabbed
Hand 1, any two handgrip 1 can be assembled.
