Description

Technical Field

[0001] The utility model belongs to the technical field related to the production of stainless steel wires, in particular to a stainless steel wire anti-fatigue detection device. Background Art

[0002] Stainless steel wire, also known as stainless steel wire, is a kind of silk product of various specifications and models made of stainless steel as raw material. It is generally divided into 2 series, 3 series, 4 series, 5 series and 6 series of stainless steel according to austenite, ferrite, duplex stainless steel and martensitic stainless steel. After the production of stainless steel wire is completed, its fatigue resistance needs to be determined. Therefore, fatigue testing is needed to determine the strength of stainless steel wire. However, it still has the following disadvantages in actual use:

[0003] When testing the fatigue resistance of stainless steel wire, the tensile force on the stainless steel wire is directly determined by the counterweight. However, when it is necessary to test the fatigue resistance of the stainless steel wire under large tensile force, more counterweights need to be added. When a large counterweight is used for testing, the force is easily unbalanced, causing inconvenience in testing.

[0004] When testing the fatigue resistance of stainless steel wire, a pulley is usually required to continuously roll on it. During the rolling process, it is stretched and loosened. Each rotation can only be stretched and relaxed once. During operation, the testing efficiency is low and the use is not convenient. Utility Model Content

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0014] The utility model solves the problem that it is not convenient to directly determine the force of the stainless steel wire through the counterweight block during the fatigue resistance detection of the stainless steel wire by arranging a base, a triangular rotating plate, a lifting block, a movable plate and a pressure sensor.

[0015] The utility model solves the problem that the detection structure can only stretch and relax one side after one rotation during the fatigue resistance detection of the stainless steel wire, resulting in low detection efficiency by arranging a base, a triangular rotating plate, a lifting block and a movable plate. The driving motor is started, and the driving motor drives the rotating shaft to rotate, thereby driving the triangular rotating plate to rotate. Through the rotation of the triangular rotating plate, the pressure roller continuously presses on the stainless steel wire restricted between the two lifting blocks, so that the stainless steel wire is subjected to intermittent and changing tension and causes fatigue. The rotation speed of the driving motor is x. When the number of stretching times m received by the stainless steel wire is determined, through the timing h, the number of stretching times m received by the stainless steel wire is 3hx. During the fatigue resistance detection of the stainless steel wire, the detection structure can stretch and relax three times after one rotation during the fatigue resistance detection of the stainless steel wire, and the detection efficiency is higher.
