Problems solved by technology

The cutting device adopts a mechanical cutting method. Although the setting of the locking device reduces the deformation and sliding of the sample during cutting, and solves the problem of cutting burrs and cracks during the cutting of the existing composite NOL ring test sample, but in During each cutting process, in order to ensure the safety of the operator, the workbench needs to move back and forth, and the locking device needs to be opened and locked repeatedly, which makes the cutting process complicated and is not conducive to the cutting of batch samples

Embodiment 1

[0032] This embodiment relates to a supporting device for cutting NOL ring test strips by water jet.

[0033] The present embodiment relates to a water jet cutting matching device for NOL ring test strips, and specifically relates to a matching device for cutting NOL ring test strips by using the water jet cutting method.

[0034] like figure 1 As shown, the supporting equipment is mainly composed of a base bottom plate 1 , a lower snap ring 2 , an upper snap ring 3 and a positioning plate 10 . Lower snap ring 2 such as figure 2 As shown in the structure, it is a plate-like structure on which a number of arc-shaped protrusions 7 are arranged, and a plurality of arc-shaped protrusions 7 are enclosed to form a circular groove body 4, and the gap between each adjacent arc-shaped protrusions 7 is In order to facilitate cutting by the water jet, a cutting groove 9 is also provided on the lower snap ring 2 below the cutout 6 . Upper snap ring 3 such as image 3 , Figure 4 As ...

Embodiment 2

[0039] This embodiment relates to a method for cutting NOL ring test strips by water jet. Using the supporting equipment described in Example 1, the cutting steps are as follows:

[0040] S1: Place the positioning plate 10 in the cutting water tank, and design the two adjacent sides on the base plate 1 to eliminate the corners, so that the position of the chamfer is placed close to the cutting origin 11 of the positioning plate 10, and ensure the design of the base plate 1 The two side edges of the chamfer are abutted against the two right-angle edges of the positioning plate 10 .

[0041] S2: Put the NOL ring to be cut into the groove body 4, then hold the handle 14 and put the upper snap ring 3 into the groove body 4, so that the NOL ring is inserted into the cavity 5 formed by the groove body 4 and the upper snap ring 3 , the upper snap ring 3 is positioned and assembled in the groove body 4 through the positioning pin 13 .

[0042] S3: Turn on the water jet cutting equipme...

Abstract

The invention discloses a method and corollary equipment for cutting NOL ring test splines by water jet, a water jet cutting method is adopted to cut an NOL ring, a notch is smooth and burr-free, the operation process is simple, potential safety hazards are avoided, batch cutting of the NOL ring test splines can be realized, and the cutting efficiency is high. According to the corollary equipment, the lower clamping ring and the upper clamping ring are adopted to form the cavity for clamping the NOL ring, and in addition, the design of the notch and the positioning plate is matched, so that the requirements of the cutting size and the cutting precision of the NOL ring test sample strip can be effectively met.

Description

technical field [0001] The invention relates to a method and supporting equipment for cutting NOL ring test strips by water jet, in particular to a method and supporting device for cutting organic fiber reinforced composite material NOL ring interlaminar shear performance test strips by water jet, which belongs to composite material cutting technology. Background technique [0002] The interlaminar shear strength of the composite material is an important index used to evaluate the interlaminar performance of the composite material, which directly reflects the interface performance between the composite material matrix and the reinforced organic fibers. The interlaminar shear strength of composites is also an important index to evaluate the effect of reinforcement surface modification. At present, the short beam method is commonly used to measure the interlaminar shear strength of composite materials. The commonly used standards ASTM2344 and GB / T1458-2008 require the test sp...
