Embodiment 1

[0025] Such as figure 1 Shown is an embodiment 1 of a wire performance testing device, including a frame 1, a first hollow chain belt 2, a first mounting plate 3 installed on the frame 1, and a reciprocating mechanism; the first hollow chain belt 2 One end is connected to the output end of the reciprocating mechanism, and the other end is fixed on the first mounting plate 3, the first mounting plate 3 and the reciprocating mechanism form a height difference, and the first hollow chain belt 2 is reciprocating between the first mounting plate 3 and the reciprocating mechanism. Bends are formed between the mechanisms. The reciprocating mechanism can be a cylinder, an electric push rod or a crank rocker mechanism and the like.

[0026] In this embodiment, the reciprocating mechanism includes a driving motor 4 and a first transmission mechanism 5, and the first transmission mechanism 5 includes a rotating wheel 501, an eccentric shaft 502 mounted on the rotating wheel 501 and ecce...

Embodiment 2

[0032] Embodiment 2 of a wire performance testing device differs from Embodiment 1 in that the device is further limited.

[0033] In one of the embodiments, the rack 1 is provided with a slide rail 101 , and the moving part 503 is provided with a slide block 5032 slidably connected with the slide rail 101 . The moving part 503 slides on the slide rail 101 through the slider 5032 to stabilize the moving direction of the moving part 503 so that the moving part 503 can drive one end of the first hollow chain belt 2 to perform linear reciprocating motion. In this embodiment, the frame 1 is provided with a fixed plate, the slide rails 101 are installed on the upper and lower sides of the fixed plate, the top and the bottom of the moving part 503 are provided with sliders 5032, the moving direction of the moving part 503 is completely fixed and Rack 1 can provide better support.

[0034] In one of the embodiments, the first mounting plate 3 is slidably connected with the frame 1 a...

Embodiment 3

[0038] Embodiment 3 of a wire performance testing device differs from Embodiment 2 in that, as Figure 4 As shown, this embodiment can test two wires at the same time.

[0039] Specifically, the first hollow chain belt 2, the first mounting plate 3 and the first transmission mechanism 5 are all installed on one side of the frame 1, and the other side of the frame 1 is mirrored with a second hollow chain belt 7, a second Mounting plate 8 and second transmission mechanism 9; The structure and connection relationship of the second hollow chain belt 7, the second mounting plate 8 and the second transmission mechanism 9 are the same as the first hollow chain belt 2, the first mounting plate 3 and the first transmission The structure and connection relationship of the mechanism 5 are consistent; the driving motor 4 simultaneously drives the rotating wheels 501 of the first transmission mechanism 5 and the second transmission mechanism 9 to rotate through the rotating shaft 401 . Th...

Abstract

The invention relates to a wire performance testing device which comprises a rack, a first hollow chain belt, a first mounting plate and a reciprocating motion mechanism, wherein the first mounting plate and the reciprocating motion mechanism are mounted on the rack; one end of the first hollow chain belt is connected with the output end of the reciprocating motion mechanism, the other end of the first hollow chain belt is fixed to the first mounting plate, the first mounting plate and the reciprocating motion mechanism form a height difference, and the first hollow chain belt forms a bent part between the first mounting plate and the reciprocating motion mechanism. A to-be-tested wire rod is fixed in a first hollow chain belt, and the first hollow chain belt is driven to be bent and straightened, so that the whole wire section of the to-be-tested wire rod is driven to be switched between a bent state and a linear state in a reciprocating manner; the bending of the to-be-tested wire rod can be realized under the condition of not applying tension to the wire rod, and the minimum value of the bending life of each point of the to-be-tested wire rod can be detected, so that the test result better conforms to the actual use condition, and the test accuracy is improved.

Description

technical field [0001] The invention relates to the field of wire rod testing equipment, and more specifically, to a wire rod performance testing device. Background technique [0002] The bending life of the wire is a key parameter of the wire product, and its measurement is of great significance for the manufacturer to improve the design process, and for the quality inspection department to evaluate whether the quality is qualified. In the standard regulations related to this test, the basic test idea is to use a certain curvature to make the wire bend at a certain angle, and it is necessary to complete the specified number of bends within a limited time. After the bending application is completed, evaluate whether the performance of the wire is degraded, such as whether there is damage or fracture, internal resistance, and whether the temperature rise is normal. [0003] In the existing test equipment or test schemes, the bending of the wire is realized by applying tensio...
