Description
Technical field
The utility model belongs to the thermal simulation experiment technical field, and providing especially is a kind of fast cold wedge shape compression jig.Be applied in the novel fast cold wedge shape compression jig on the GLEEBLE hot modeling test machine, can improve the maximum natural cooling speed of dynamic compression condition.
Background technology
The controlled rolling and controlled cooling technology is present metallurgical steel rolling field, improves metal material performance and a kind of important means of wanting that reduce production costs.Hot modeling test machine can be simulated hot rolling and the cold process of control, is the important research tool in Metal Material Science field.
Along with the steel rolling equipment and the control-cooling equipment of the big production in scene are more and more advanced, roll-force and cooling power are also more and more stronger, and scientific research personnel's range of choice is more and more wideer, also requires increasingly high to the thermal modeling test test parameters.
Thermal modeling test slave unit functional perspective can be divided into two major parts: envelope test and dynamic test.Envelope test comprises welding heat affected zone, welding CCT, static CCT, TTT, Technology for Heating Processing simulation or the like.Dynamic test comprises resistance of deformation, static dynamic recrystallization, dynamic CCT, TTT, drawing by high temperature, high temperature compressed steel rolling process simulation or the like.
In the uniaxial compression experiment, the maximum controlled cooling velocity after the distortion is an important test parameters, and (idea: equipment generally can mark cooling power, but only is some absolute ratings under the static condition.The cooling power of equipment under the different working condition is different, under the static condition under cooling rate and the dynamic condition cooling rate because method of clamping different, so do not possess comparability)
Maximum natural cooling rate under the imported with original packaging wedge shape compression jig dynamic condition can only arrive for 15 degree/seconds (800 ° C-500 ℃).Along with the steel rolling equipment and the control-cooling equipment of the big production in scene are more and more advanced, roll-force and cooling power are also more and more stronger, and this analog parameter can't satisfy the test demand.
Through discovering, can strengthen the thickness of wedge shape jig, reduce to support the length of jig, in fixing space, adjust the ratio between the two, reach the purpose of optimization.Through adjustment, wedge shape heating jig has strengthened the surface of contact with current return, and littler thereby contact resistance becomes, heat-sinking capability is stronger, and physical strength is also bigger, thus the life-span of improving wedge shape jig and heating electrode (tungsten carbide hammering block).And because heat-sinking capability is strengthened, it is faster that the cooling velocity of test can become, and also directly improved the ability of equipment.
Summary of the invention
The purpose of the utility model is to provide a kind of fast cold wedge shape compression jig, has strengthened heat-sinking capability and cooling velocity.
The utility model comprises wedge shape compression jig 2, wildcard-filter style tungsten carbide hammering block groove 1, compression support pad 3; Cylindrical carbonization tungsten hammering block 4 is put into wildcard-filter style tungsten carbide hammering block groove 1, and cylindrical anvil subpad 5 is put in cylindrical carbonization tungsten hammering block 4 outer ends,, fixes with fastening bolt at the rear portion of wedge shape compression jig 2 with compression support pad 3 pads.
The utility model is selected the cylindrical anvil subpad 5 of different-thickness for use, regulates the length at cylindrical carbonization tungsten hammering block 4 outstanding positions, the contact area that just cylindrical carbonization tungsten hammering block 4 and wildcard-filter style tungsten carbide hammering block groove are 1.
The principle of the utility model is: the GLEEBLE hot modeling test machine adopts the working method of resistance heated conduction cooling; Novel fast cold compression wedge shape jig has strengthened the contact area with current return; Can also regulate the contact area between cylindrical carbonization tungsten hammering block and wildcard-filter style tungsten carbide hammering block groove through the cylindrical anvil subpad; It is littler that thereby contact resistance becomes, and heat-sinking capability is stronger, between isothermal and cooling velocity, reaches a desirable balance.
Cylindrical anvil subpad diameter is identical with cylindrical carbonization tungsten hammering block diameter, and thickness is 5mm-15mm, can process different-thickness.
The described wedge shape compression of the utility model jig adopts the brass material; The cylindrical anvil subpad adopts the straight carbon steel material; The compression support pad adopts the high-strength steel material.
The advantage of the utility model is:
1, pass through to strengthen the contact area of jig and current return, thereby make contact resistance become littler, heat-sinking capability is stronger, has strengthened the cooling power of wedge shape compression jig, the serviceable life that can also improve heating electrode (tungsten carbide hammering block).
2, simple in structure, easy to install.Effect is remarkable, and maximum natural cooling speed is brought up to (between 800 degree to 500 degree) more than 30 degree/seconds under the dynamic compression condition from 15 degree/seconds.
