Problems solved by technology

Although this method is simple and practical even for a certain type of
Specifically, the existing electrical appliances include various types such as insulating ladders, insulating rods, insulating operating rods, bottle racks, etc., and the length and shape of each type of sample are different. This simple support mechanism The applicability is poor, and it cannot meet the positioning requirements of various samples, and its reliability and stability are difficult to guarantee; due to the loading by counterweights, the loading rate often cannot meet the test requirements, resulting in poor repeatability of the test. Inaccurate results; labor-intensive and inefficient as specimen repositioning and loading are done manually

Abstract

The invention discloses a bending tester for tools and utensils. The bending tester comprises a guide rail, a universal tester loading part and two mobile terminals and is characterized in that the loading part is fixed on the guide rail; the guide two mobile terminals are slidably arranged on the guide rail and respectively arranged at two ends of the universal tester loading part; each mobile terminal comprises a frame and a bracing frame arranged above the frame; each frame comprises a frame body, a roller cooperated with the guide rail and a roller locking mechanism; and each bracing frame is provided with supporting wheels used for placing of a sample. The bending tester has the advantages of good versatility, high test accuracy, low labor intensity and high test efficiency.

Description

technical field [0001] The invention relates to the field of testing equipment, in particular to the field of bending testing machines, in particular to a bending testing machine used for tubular live safety tools and tubular composite materials in the electric power industry. Background technique [0002] The bending performance of tubular live safety tools and tubular composite materials in the power industry is an important indicator for evaluating the performance of the materials and products. At present, there is no standard equipment for testing them in the market. Commercially available bending testing machines or universal testing machines are mostly used for small-section samples such as steel pipes, steel bars, and plastic pipes. Their built-in fixtures cannot meet the testing needs of tubular live safety tools and tubular composite materials in the power industry. Due to the special shape and large length of tools and appliances in the electric power industry, the...
