Abstract
The utility model provides a test device is peeled off to PE electric smelting subassembly, the device includes a tensile test machine, has arranged PE electric smelting subassembly specimen sample clamping mechanism on the workstation of this tensile test machine, utilize the tensile test machine to peel off specimen sample, obtains to peel off the result. Comparing the extrusion and peeling off the mode, it operates convenient and fast more, the acquisition to peel off the result truer, accurate, can judge the bonding strength of electrocast sleeve and tubular product according to this result, make quantitative analysis to the welding quality of subassembly, and reach a conclusion.
Description
Technical field
The utility model belongs to PE electric smelting assembly property technical field of measurement and test, relates to a kind of PE electric smelting assembly peel test device, is mainly used in DN63 and following PE electric smelting assembly sample disbonded test.
Background technology
By the test method of GB/T19806-2005 " the extruding peel test of polyethylene electric-melting assembly ", common, use the PE tube portions of mechanism to PE electric smelting assembly such as compression test to extrude to the way of DN63 and following PE electric smelting assembly sample peel test, but test effect is barely satisfactory, the electric heating melting junction of electric melting sleeve and PE tubing can not realize effective stripping, thus cannot make qualitative and quantitative test to the welding quality of assembly.
Summary of the invention
The purpose of this utility model is, for the deficiency of above-mentioned background technology, provide a kind of simple to operate, save trouble and labor, convenient and practical, be especially applicable to DN63 and following PE electric smelting assembly peel test device.
The technical solution of the utility model is: a kind of PE electric smelting assembly peel test device, this device comprises a cupping machine, the worktable of this cupping machine is furnished with PE pipe assembly test sample clamping mechanism, utilize cupping machine to carry out disbonded test sample, and obtain the value of thrust needed for peeling off.
Described test specimen clamping mechanism comprises base, sample clamping seat, described base is fixed on to be stretched on the worktable of testing machine, described sample clamping seat is arranged on base, and its joint portion is dovetail, slot fit structure, and sample clamping seat can horizontally slip on base; Described sample mount pad end face has briquetting and holding screw, and for fixation test sample, during test, the termination of test specimen is by the grips of cupping machine.
The beneficial effects of the utility model are: this device utilizes cupping machine to carry out disbonded test sample, compare extruding to peel off, its faster and more convenient operation, the peel results obtained is more true, accurate, the bond strength of electric melting sleeve and tubing can be judged, quantitative test is made to the welding quality of assembly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the structural drawing of this device;
Fig. 2 is the A direction view (expressing for clear, test specimen not shown in FIG.) of Fig. 1;
Code name implication in figure: 1-tension test machine worktable; 2-tension test machine grip holder; 3-base; 4-chute; 5-sample clamping seat; 6-briquetting; 7-holding screw; The electric melting sleeve layer of 8-PE pipe assembly; The tubing layer of 81-PE pipe assembly.
Embodiment
See Fig. 1,2, this PE electric smelting assembly peel test devices, comprise a cupping machine, the worktable of this cupping machine is furnished with PE electric smelting assembly test sample clamping mechanism, utilizes cupping machine to carry out disbonded test sample, and obtain peel results.
Described test specimen clamping mechanism comprises base 3, sample clamping seat 5, described base 3 is fixed on to be stretched on the worktable 1 of testing machine, base 3 has dovetail groove 4, has dovetail bottom described sample mount pad 5, be assemblied in dovetail groove 4, sample mount pad 5 can be horizontally slipped; Described sample mount pad 5 end face there are briquetting 6 and holding screw 7, for fixation test sample.During test, the termination of test specimen is clamped by the chuck 2 of cupping machine.
Using method of the present utility model is as follows:
For convenience of clamping, by PE electric smelting assembly cut growth strip test specimen, Sample Width mates with the end face width of clamping seat, from one end of sample, tubing layer and electric melting sleeve layer is torn certain length.
Be placed on by sample on clamping seat, upwards, electric melting sleeve layer 8 is downward for tubing layer 81, tearing notch is between two briquettings 6, and the tubing layer 81 before tearing notch pushed down by the briquetting on the left of wherein illustrating, and fixed by its screw, the sample after tearing notch pushed down by another briquetting, and fixed by its screw.
Tubing layer 81 termination of tearing is clamped by the chuck 2 of testing machine, is then shifted on the left of chute 4 by clamping seat 5, makes tearing notch not just to chuck 2, and tubing layer 81 tensioning of will tear.
Open testing machine, make chuck drawing pipes layer 81 upward, continue to tear from electric melting sleeve layer 8 face of weld, the value of thrust that cupping machine measures, the i.e. value of peeling force, can judge the bond strength of electric melting sleeve and tubing according to this value, make quantitative test to the welding quality of assembly.
It should be noted that if clamping seat is arranged on immediately below testing machine chuck, then chuck have tube portions directly over pulling force, like this in stripping process, easily make tubing layer 81 rupture, the object peeled off from electric melting sleeve layer cannot be realized.
