Drawing test device for processing of nylon heat insulation strip

Abstract

The invention provides a drawing test device for processing of a nylon heat insulation strip. The device comprises a base and a clamping assembly. First sliding grooves are formed in the two ends of one side of the top of the base correspondingly; a sliding plate is movably mounted on the first sliding groove; a U-shaped frame is arranged on the sliding plate; a first pneumatic cylinder is arranged in the middle of the top of the U-shaped frame; the output end of the first pneumatic cylinder penetrates through the U-shaped frame and is provided with a clamping plate; a second sliding groove isformed in the middle of the top of the base, and a connecting frame is arranged at one end of the second sliding groove; a connecting block extending into the second sliding groove is arranged at thebottom of the sliding plate; and a tension meter is connected between the connecting block and the connecting frame. The first pneumatic cylinder presses the clamping plate downwards to fix one end of the nylon strip, the clamping assembly clamps the other end of the nylon strip, the nylon strip can be drawn for testing through movement of the sliding plate, the toughness value of the nylon stripcan be obtained through the degree difference of the tension meter, and testing is more convenient.

Description

technical field [0001] The invention relates to the technical field of production of heat-insulation strips, in particular to a drawing test device for processing nylon heat-insulation strips. Background technique [0002] Nylon heat insulation strip is composed of nylon 66% + 25% glass fiber and other materials. It has the following characteristics: high mechanical strength, it can be connected to hardware accessories while bearing tensile and shear stress; the thermal expansion coefficient is close to that of aluminum profiles, ensuring that it can withstand large temperature differences. Under normal circumstances, the heat insulation strip is closely combined with the aluminum material; the heat deformation temperature is high, which can meet the subsequent treatment of the profile surface; the dimensional accuracy is high, ensuring the airtight and watertight performance of the window; excellent anti-aging and anti-ultraviolet performance, long service life; chemical cor...

AI Technical Summary

Problems solved by technology

[0003] In the production of nylon heat insulation strips, it is necessary to perform a pulling test on the finished product to obtain its toughness value. In the prior art, workers generally pull it manually, which is troublesome to test. Even if there are some pulling equipment, it is just a simple clamping Pulling both ends of the nylon strip has a single function, and the test data is very one-sided and not representative. Therefore, the present invention proposes a drawing test device for nylon heat insulation strip processing to solve the problems existing in the prior art.
