Description

Technical Field

[0001] The invention relates to the technical field of enameled wire performance testing, in particular to a ceramic-enamel composite insulated wire flame retardancy testing device. Background Art

[0002] Ceramic-enamel composite insulated wire is a composite wire formed by painting the surface of an aluminum wire with a ceramic film layer, and is a type of enameled aluminum wire. After the enameled wire is produced, samples are usually randomly taken to test the flame retardancy of the enameled wire. During the test, the enameled wire is usually placed directly into the oven and baked or burned with an open flame to determine the flame retardancy of the enameled wire. When the enameled wire is tested in this way, the enameled wire is in a natural state, but the enameled wire may be stretched or twisted when it is actually used. After the enameled wire is stretched or twisted, it may affect the flame retardancy of the enameled wire. Therefore, the flame retardancy test of the enameled wire is not very comprehensive and accurate. Summary of the invention

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] Example 1

[0019] like Figure 1 and Figure 2As shown, the present embodiment discloses a flame retardancy testing device for ceramic-enamel composite insulated wire, comprising a box body 1, a box door 11 is provided on one side of the box body 1, a burning device 2 is provided in the box body 1, and stretching devices 5 are provided on both sides of the box body 1. The stretching device 5 comprises a stretching hydraulic cylinder 5, and the stretching hydraulic cylinder 5 is fixed on one side of the box body 1. The telescopic end of the stretching hydraulic cylinder 5 is fixedly connected to the installation box 52, and a first motor is installed in the installation box 52. A rotating shaft 53 is installed on the main shaft of the first motor, and one end of the rotating shaft 53 is fixedly connected to a clamping device 54. The clamping device 54 adopts a clamping device that can clamp the enameled wire in the prior art. This is the prior art and will not be repeated here.

[0020] In this embodiment, the two ends of the enameled wire to be tested are first clamped by the clamping device 54, and the installation box 52 is pulled by the stretching hydraulic cylinder 5 to move, and the two installation boxes 52 move in opposite directions, so that the enameled wire is stretched, and then the enameled wire is sprayed with fire by the burning device 2, so as to test the flame retardant performance of the enameled wire in the stretched state. At the same time, the first motor drives the rotating shaft 53 to rotate, so that the rotation directions of the two rotating shafts 53 are opposite, so that the enameled wire is twisted, so that the flame retardant performance of the enameled wire in the twisted state can be tested.

[0021] Example 2

[0022] On the basis of Example 1, in order to test whether the flame retardant performance of the enameled wire is affected after the insulation layer is damaged, a guide rod 12 is fixedly connected in the box body 1, a slider 14 is slidably connected to the guide rod 12, a screw rod 13 is rotatably connected in the box body 1, and the screw rod 13 is threadedly connected from the screw nut of the slider 14. A third motor 15 is installed on one side of the box body 1. The third motor is used to drive the screw rod 13 to rotate, so that the third motor can drive the slider 14 to reciprocate horizontally along the guide rod 12 by forward or reverse rotation. A lifting hydraulic cylinder 3 is installed on the slider 14, and a skin breaking device 4 is installed at the telescopic end of the lifting hydraulic cylinder 3. The skin breaking device 4 includes a base plate 41, a knife seat 42 is fixedly connected to the lower side of the base plate 41, a first arc groove 43 is provided on the lower side of the knife seat 42, and an arc blade 44 is installed in the first arc groove 43. The lifting hydraulic cylinder 3 drives the base plate 41 to descend, so that the enameled wire is located in the first arc groove 43. At this time, the arc blade 44 contacts the enameled wire, and as the slider moves horizontally, the insulating layer of the enameled wire is cut by the arc blade 44. In this way, it can be tested whether the flame retardant performance of the enameled wire is affected after the insulating layer of the enameled wire is damaged.

[0023] In order to achieve a better effect of destroying the insulating layer of the enameled wire, a supporting hydraulic cylinder 45 is installed on the base plate 41, and the telescopic end of the supporting hydraulic cylinder 45 is fixedly connected to the supporting plate 46, and the upper side of the supporting plate 46 is fixedly connected to the supporting seat 47, and the upper side of the supporting seat 47 is provided with a second arc groove 48. When the supporting seat 47 contacts the knife seat 42, a circular cutting channel is formed between the second arc groove 48 and the first arc groove 43. During the cutting process, the lower side of the enameled wire is supported by the supporting seat 47, so that the enameled wire is not easily compressed and bent during the cutting process, thereby ensuring the intact cutting of the insulating layer of the enameled wire.

[0024] Example 3

[0025] In order to further improve the burning effect of the enameled wire, the burning device is specially designed, as follows: the burning device 2 includes a ring 22, the ring 22 is fixed on the slider 14 through an "L"-shaped bracket 21, the ring 22 is slidably connected to the slide 24, and a flamethrower 28 is installed on one side of the slide 24. A toothed ring 23 is installed on the outer side of the ring 22, a clearance groove 25 is provided on the slide 24, and the toothed ring 23 passes through the clearance groove 25. A second motor 27 is installed on one side of the slide 24, and a gear 26 is installed on the main shaft of the second motor 27. The gear 26 is located in the clearance groove 25, and the gear 26 is meshed with the toothed ring 23. When in use, the enameled wire passes through the ring 22, and the second motor 27 drives the gear 26 to rotate forward and backward, so that the slide 24 moves back and forth along the ring 22, so that the enameled wire is burned from all sides, thereby improving the burning effect of the enameled wire and indirectly improving the accuracy of the flame retardancy test of the enameled wire.
