At present, all cutter with grinding wheel sheets are when sample cuts, requirement specimen size determines the length of cutting sample, and in the process of taking measurements and cut, there will be error unavoidably, the dimensional accuracy after causing sample to cut is inadequate, affects the accuracy of follow-up performance test results, and this impact is particularly outstanding when Charpy impact sample cuts, the Charpy impact blank sample particularly after weld thermal simulation.
General pendulum hammering blow sample adds man-hour, usually first the milling of blank sample is become the square bar of 10.5mm × 10.5mm × L (L is length, is greater than 55mm), then on grinding machine, is ground to 10mm × 10mm × L.Afterwards, by abrasive wheel cutting machine, be the standard pendulum hammering blow base sample that the Charpy impact blank sample of L cuts into 55 ± 0.6mm by length, finally, by Charpy impact sample break broaching machine, V-type or the processing of U-shaped breach carried out to sample.And when processing weld thermal simulation Charpy impact sample, in order to ensure gap regions in thermal modeling test district (i.e. HAZ district), during cutting, need strict control HAZ district two ends length to be 27.5 ± 0.3mm.
In standard GB/T229-2007 " metal material Charpy pendulum impact test method ", regulation Charpy impact specimen length is of a size of 55 ± 0.6mm, common metering system can make Charpy impact specimen length dimensional discrepancy larger, be above standard tolerance, and this will directly affect the Charpy impact results of property of sample.Especially less to HAZ region weld thermal simulation Charpy impact sample, once notch size deviation a little, will be huge on the impact of performance.Chinese patent CN201344870Y, CN201979148U, CN202180363U and CN201979148U proposes the fixture for processing such as a kind of Charpy impact sample sawing machine, lathe, lathe respectively, but these patents all fail to solve the difficult problem that grinding wheel cuts Charpy impact sample low precision.
Utility model content
For the problems referred to above, the utility model provides a kind of Charpy impact sample cutting fixture, to solve Charpy impact sample machining accuracy problem, improves processing sample quality, guarantees the accuracy of sample Charpy impact the performance test results.
For achieving the above object, the utility model adopts following technical scheme:
A kind of Charpy impact sample cutting fixture primarily of locating convex block, sample groove, spiral pieces, baffle plate, scale, the part such as set bolt composition; Locating convex block is fixed on the bottom of fixture by screw, and spiral pieces is adjacent with baffle plate, and scale is positioned at the top of cutting clamper, and set bolt is positioned at the side of cutting clamper.
Further, in described Charpy impact sample cutting fixture locating convex block dimensions need with cutter with grinding wheel sheet groove match, be fixed on the bottom of fixture by screw, cutter with grinding wheel sheet groove can be put into.
Further, in described Charpy impact sample cutting fixture, sample groove is square, is convenient to place Charpy impact blank sample.
Further, in described Charpy impact sample cutting fixture, spiral pieces is adjacent with baffle plate, adds man-hour, and Charpy impact blank sample end, near baffle plate, adjusts the Cutting Length of Charpy impact blank sample by observation scale and adjustable screw slide block.
Further, in described Charpy impact sample cutting fixture, scale is positioned at the top of fixture cutting clamper, and the starting point of scale is positioned at the end of cutting sample side.
Further, in described Charpy impact sample cutting fixture, set bolt is positioned at the side of cutting clamper, for fastening Charpy impact blank sample.
Compared with prior art, the utility model at least has following beneficial effect:
On fixture top, scale is set, adjusted the Cutting Length of Charpy impact blank sample by observation scale and adjustable screw slide block, the accuracy of Charpy impact sample sample preparation can be increased substantially, guarantee the crudy of sample, significantly improve Charpy impact sample working (machining) efficiency, reduce personnel labor intensity.And fixture is used for plain wheel sheet cutting machine in the utility model, structure is simple, easy to use, be easy to handling.
