Description

Technical Field

[0001] The invention relates to the technical field of cutting testing, in particular to a saw-proof clothing cutting device and a testing method. Background Art

[0002] Anti-saw clothing is a functional protective clothing worn by relevant personnel when using chainsaws. It can effectively resist chain saw cutting and ensure the personal safety of chain saw users. At present, foreign countries attach great importance to the quality of anti-saw clothing, and have issued a series of evaluation standards such as ISO 11393-1:2018 "Protective clothing for users of handheld chainsaws-Part 1: Chain saw cutting test bench". The existing anti-saw clothing on the market mainly uses multi-layered high-performance textile materials to block and brake chain saws to prevent chain saws from causing harm to the human body.

[0003] The anti-saw performance testing equipment uses electric energy to drive the chain to rotate, and the chain speed and cutting kinetic energy can be adjusted. The chain is accelerated to the specified speed by the motor, and then the power device is disconnected to ensure that the chain rotates only by the inertia of the shaft, flywheel and other rotating parts without external force. During the rotation of the chain, it falls freely from a certain height (2mm), then contacts and cuts into the sample until it stops rotating after all kinetic energy is consumed. Check whether the test sample is completely cut through at a specific chain speed (that is, whether the innermost layer of the sample is damaged) to determine the anti-saw level of the sample.

[0004] The braking principles of the anti-saw performance testing equipment include chain sliding, blocking, and chain braking. The braking principle of chain sliding is that the chain slides over the surface of the anti-saw material without cutting into the material, relying on friction resistance to consume kinetic energy to achieve braking; the braking principle of blocking is that anti-saw materials such as fibers and yarns are drawn into the chain saw (sprockets, chains, guide plates, etc.), blocking the chain from rotating until it stops; the test principle of chain braking is that the anti-saw material has a high cutting resistance, continuously absorbs rotational kinetic energy, reduces the chain speed, and finally stops the chain. According to the standard requirements, the anti-saw performance testing equipment needs to meet five basic parameter requirements: chain speed, moment of inertia, contact pressure, chain deflection, and stop time.

[0005] At present, the existing anti-saw clothing cutting test device lacks precise adjustment mechanisms in cutting height, angle and front and back directions, which limits the adaptability and flexibility of the anti-saw clothing cutting device and makes it difficult to meet diverse cutting needs; at the same time, the positioning and clamping method of the anti-saw clothing before cutting is not stable and accurate enough, which can easily lead to displacement during the cutting process, affecting the accuracy and safety of the cutting; in addition, the lack of multi-angle flipping and multi-position adjustment functions limits the comprehensiveness and efficiency of the cutting test, and increases the complexity of the operation process and manual intervention. Therefore, it is necessary to design a corresponding technical solution to solve this problem. Summary of the invention
