Background technology
Tension test to the non-tubular shape metal product, for on product, downcutting sample, and be made into the two ends of sample cylindrical, the chuck of drawing machine clamps two cylinder-shaped ends of sample and stretches, make clavate sample (below be referred to as coupon) lengthening deformation to fracture, but for some non-cylinder metal materials, especially thin sheet metal, then the two ends of coupon can not be made to standard-sized cylindrical, be that coupon can not be made the standard coupon, then on having now, can't test by the cupping machine of chuck clamping sample.In China Patent No. is ZL200520048040.X, name is called in the patent documentation of " the extension test instrument that the metal tensile test machine is used ", a kind of metal tensile test instrument is disclosed, it is the clamping step of end design with two tool bodies, be connected between two pull bars of torque arm of cupping machine, pin is drawn in one of the other end design of tool body, tested ring specimen is enclosed within draws on the pin, realization is to the tension test of sample ring, it has following deficiency, 1, tool body with the level can not with by the fixing drawing machine clamping of sample of chuck, 2, it is by drawing guide to connect to the fixed form of sample, only suitable ring specimen, inapplicable to coupon.
The utility model content
The utility model provides a kind of anchor clamps that can carry out clamping to non-standard coupon, and non-standard coupon can be tested on existing test drawing machine by chuck clamping sample.
Above technical matters solves by following technical proposal: the metal tensile test anchor clamps, comprise two chuck body, described chuck body is provided with linkage section and construction section successively, described linkage section is cylindrical, the free end of described construction section is provided with hanging groove, and described hanging groove is communicated with the end face of described construction section.During test the two ends of coupon are made the hanging head with the hanging groove form fit, the two ends of coupon are articulated in the hanging groove of two chuck body, the linkage section with chuck body is clamped in the chuck of metal tensile test machine then, can carry out tension test to coupon.
As preferably, described hanging groove is "T"-shaped, and described hanging groove comprises first cell body and second cell body, and described first cell body is communicated with the end face of described construction section." first cell body " is meant that part of cell body of the perpendicular stroke of hanging groove correspondence " T " word, and " second cell body " is meant that part of cell body of the horizontal stroke of hanging groove correspondence " T " word, and "T"-shaped mode articulates, and coupon is more steady with being connected of hanging groove.
As preferably, described construction section is a right cylinder, and the diameter of described construction section is greater than the diameter of described linkage section, described linkage section and described construction section coaxial cable.Two sections all is the right cylinder handling ease, two sections axis is consistent easily, make when test two chuck body and the coupon three be in same straight line, the power that coupon can not be sheared, data are more accurate, coupon also is difficult for dropping, and the diameter of construction section is can also satisfy requirement of strength in order to guarantee after construction section has been offered hanging groove greater than the diameter of linkage section.
Preferred as another, described construction section is a right cylinder, described cylindrical diameter is greater than the diameter of described linkage section, described linkage section and described construction section coaxial cable, the free end of described construction section caves in and extends axially the formation mounting plane, and described "T"-shaped mounting groove is positioned on the described mounting plane.Economize material.
As preferably, on described construction section free end, be arranged with protective jacket, described protective jacket links to each other with described construction section by web member.Prevent that coupon from coming off, eject when preventing test bar fracture security incident takes place.
As preferably, the inwall of described protective jacket is provided with press strip, and described press strip is towards described hanging groove.In cover press strip is set, and allows press strip towards hanging groove, the more effective coupon that prevents skids off mounting groove.
The utlity model has following advantage, by having designed these anchor clamps, non-standard coupon is tested not needing to change under the situation of existing cupping machine, enlarged the usable range of drawing machine, improved the utilization factor of drawing machine.
