[0004] As a surface corrosion protection method for metal parts, cold galvanizing refers to the rotation of the rotating parts plating tank under room temperature conditions, so that the mutual collision of the medium in the tank can be achieved to form a plating layer. During the cold galvanizing process of ω type elastic strip, due to the continuous rotation of the plating barrel, the elastic strips are easily hooked and entangled together, so that it is difficult to separate them after galvanizing, and a large amount of manual work is required to separate the elastic strips.

[0020] The utility model discloses the mode of example and with reference to the attached drawing is explained, wherein:
[0021] Figure 1 It is the structure schematic diagram of the utility model;
[0022] The figure mark includes: 1-net cover, 2-omega type elastic strip. DETAILED DESCRIPTION
[0023] A kind of anti-winding device for omega type elastic strip cold galvanizing process, as shown in Figure 1 Including: including net cover 1, omega type elastic strip 2.
[0024] The two limbs of the omega type elastic strip 2 are respectively worn into the two ends of the net cover 1, the penetration depth is greater than 10mm, and the movable distance of the two ends is 15mm.
[0025] The net cover 1 adopts a porous structure, which can ensure that the elastic strip 1 can smoothly fuse with the product during surface treatment, and avoid the problem of plating leakage due to the wrapping of the net cover 1.
[0026] The net cover 1 adopts a structure type of large at both ends and small in the middle, which can limit the movement of the two limbs of the elastic strip and ensure that the net cover will not fall off or slide randomly on the elastic strip during surface treatment due to excessive movement displacement.
[0027] The net cover 1 is made of a material with good ductility and high toughness, which can ensure that the net cover can be smoothly worn into the omega type elastic strip 2 and be easily removed after surface treatment.
[0028] The material of the net cover is selected from non-metallic materials with good ductility and high toughness.
[0029] The mesh sleeve aperture needs to be larger than the diameter of the spring strip raw material, to ensure that there is sufficient clearance between the spring strip and the mesh sleeve, and the clearance value is usually (3-5) mm. In this way, it can ensure that the plated medium is in sufficient contact with the spring strip.
[0030] The length of the mesh sleeve should not be less than 90 mm, and the length of the spring strip flat section passing into the mesh sleeve should not be less than 10 mm.
[0031] The wire diameter of the mesh sleeve should not be less than 1 mm, to ensure that it has sufficient strength.
[0032] The two ends of the mesh sleeve are respectively passed into the two limbs of the spring strip, to form a closed loop, to prevent the two limbs from hooking and entangling each other.
[0033] The working principle of the utility model is as follows: the two limbs of the spring strip are limited by the mesh sleeve, and the spring strip and the mesh sleeve form a closed loop, which effectively avoids the mutual entanglement of the two limbs due to exposure during the cold galvanizing process. In addition, the multi-hole mesh sleeve structure can effectively avoid problems such as plating leakage and uneven plating of the spring strip due to being wrapped.
