Abstract
The utility model discloses a kind of cross-linked polymer heat and extend proving installation counterweight modified node method, comprise counterweight and counterweight bar, described counterweight arranges breach, and center is positioned on counterweight bar, described counterweight bar is fixedly attached on fixture, and counterweight bar bottom is provided with chain-wales.The utility model adopts notched counterweight, and realizing counterweight can be easy to loading and unloading, adopts chain-wales, and place counterweight steady, easily take out, one-piece construction is simple.
Description
Technical field
The utility model belongs to cross-linked polymer performance testing device field, and particularly a kind of cross-linked polymer heat extends proving installation counterweight modified node method.
Background technology
Cross-linked polymer, especially crosslinked polyethylene are widely used in the fields such as cable, tubing and film, and hot extensibility is its main performance index.Along with the development of technology, the progress of science, cross-linking method is environmental protection and energy saving more and more.For crosslinked polyethylene, silane one step cross-linking method gains great popularity.
Natural-crosslinked cardinal principle is the moisture that cross-linked polymer absorbs in air, crosslinked under the effect of catalyzer.According to the literature and facts have proved, the crosslinking rate of crosslinked polyethylene becomes negative correlation with crosslinking degree with its thickness.Thickness is thicker, and crosslinking rate is slower, and crosslinking degree is lower.The thickness of Standard test sample is 1mm, and the actual a few tenths of a mm that is used in is between several millimeters.So, to the research of the different-thickness emphasis by natural-crosslinked method after being.
Current hot extension apparatus used is bolted clamping sample two ends, lower end adopts to be threaded by a counterweight bar and is fixedly attached on the fixture of lower end, cylindricality with through hole centered by counterweight, counterweight is inserted in counterweight bar to place, counterweight bar lower end is bent into a ring-type, prevent counterweight from dropping, when adopting the sample of different-thickness to test, when needing to load different power, need to change counterweight, after counterweight bar need be dismantled, counterweight could be loaded and unloaded, pick and place very inconvenient, and ring-type and counterweight bar transition position are arc, counterweight easily blocks after placing and, not easily take out, counterweight bar adopts with fixture and is threaded, long-time dismounting easily causes thread pitch to become large, easily loosen, during test, counterweight swings and impacts test, stringency of test reduces.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of cross-linked polymer heat to extend proving installation counterweight modified node method, handling counterweight is convenient, and structure is simple, and device is reliable, and test accuracy is high, to overcome prior art problem.
The technical scheme that the utility model is taked is: a kind of cross-linked polymer heat extends proving installation counterweight modified node method, comprise counterweight and counterweight bar, described counterweight arranges breach, and center is positioned on counterweight bar, described counterweight bar is fixedly attached on fixture, and counterweight bar bottom is provided with chain-wales.
Described counterweight gap width is greater than counterweight shank diameter 1/5th, indentations bottom arc transition, and center of arc is concentric with counterweight center of gravity.
Described chain-wales adopts nut to be fixedly attached on counterweight bar, and counterweight bar bottom diameter of screw is less than counterweight shank diameter.
When described counterweight places at least two, adopt opposed notches to intersect and place.
Described counterweight bar adopts set nut locking to be connected on fixture.
Described counterweight accuracy class adopts more than 2 grades.
The beneficial effects of the utility model: compared with prior art, the utility model adopts notched counterweight, realizing counterweight can be easy to loading and unloading, adopt chain-wales, placement counterweight is steady, easy taking-up, gap width is greater than counterweight shank diameter, be convenient to the taking-up of counterweight, keep with one heart, carrying can be allowed to balance, prevent counterweight landing, adopt the separately design of chain-wales and counterweight bar, be convenient to manufacture, employing nut connects, be convenient to install, diameter of screw is less than counterweight shank diameter, be easy to chain-wales and form location, it is more firm to lock, the mode of placing of intersecting prevents counterweight not when center, still can keep stable, nut lock can prevent loosening of counterweight bar and produce swing, assurance device is reliable, improve test accuracy, the counterweight precision adopted can meet test accuracy.
