Description
Technical field
The utility model relates to metal material mechanics technical field of performance test, refers to particularly a kind of super thin metal strip high temperature tension test fixture.
Background technology
For studying the rolling mill practice of super thin metal strip and investigating the mechanical behavior under high temperature of this type of strip, must carry out the high temperature tension test of associated materials.At present, carry out high temperature tension test according to national standard " GB/T4338-2006 Metal Materials At High Temperature stretching test method " for sheet material, generally adopt parallel-segment two ends band pin-and-hole sample.But often in drawing process, there will be pin-and-hole place to deform for ultra-thin sample, the even phenomenon such as pin-and-hole place cracking, testing machine imposed load part is shared by the distortion of pin-and-hole place, cause the actual institute of sample parallel portion bearing load to be less than testing machine output valve, cause test result deviation excessive and invalid.In routine work, can reduce the distortion of pin-and-hole place by increase many group pads in pin-and-hole both sides, but pad not bonding (general bonding agent cannot bear high temperature) is in pin-and-hole both sides, always gapped, cannot thoroughly solve pin-and-hole and in drawing process, be out of shape the even phenomenon of cracking.
Summary of the invention
The purpose of this utility model to provide exactly one be not with pin-and-hole, clamping closely, centering is convenient, operate super thin metal strip high temperature tension test fixture easily.
For achieving the above object, the super thin metal strip high temperature tension test fixture that the utility model is designed, comprise U-shaped chuck body, bolt, be provided with the holder of pull bar connecting hole, described U-shaped chuck body is equipped with the bolt hole coordinating with bolt on two side, described holder is connected with U-shaped chuck body bottom surface, it is characterized in that: it also comprises the die fixture block and the punch fixture block that are equipped with threaded hole, described die fixture block and punch fixture block and clip slot are set and are joined merga pass bolt and threaded hole is fixed, on die fixture block and punch fixture block, be respectively equipped with groove and boss that phase scarf closes.
Further, described clip slot bottom surface is provided with the chute that allows die fixture block and punch fixture block to slide; Described chute outer wall is provided with rule, in the time that the center line of adjusting die fixture block and punch fixture block is aimed at scale, can remain in same plane.
Further, on the interface of described die fixture block and punch fixture block, be equipped with zigzag projection; Increase the friction force between sample and die fixture block and punch fixture block, avoided skidding.
Again further, described U-shaped chuck body two ends are arranged with fixture fixed pin, described die fixture block is provided with the fixture block register pin corresponding with fixture fixed pin with punch fixture block sidewall, between described fixture fixed pin and corresponding fixture block register pin, is provided with back-moving spring.
The utility model has the advantage of: employing sample is fixed by die fixture block and punch fixture block but not is with pin-and-hole fixedly to carry out high temperature tension test, there will not be the distortion of pin-and-hole place to cause the phenomenon that test result is invalid; Die fixture block and punch fixture block surface of contact are provided with zigzag projection, can play the effect that increases surface of contact friction force, can prevent that for high-strength steel sample skidding from appearring in sample in the time stretching; Promote fixture block locking sample by screwed in place bolt, coupling mechanism force has ensured that sample is compressed completely by two fixture blocks; It is simple in structure, and low cost of manufacture is easy to use, is easy to promote.
