Description

Technical Field

[0001] The invention relates to an anti-winding device used in a cold galvanizing process of an ω-shaped spring bar. Background Art

[0002] As one of the important components of the fastener system, the spring clip is also an indispensable component for connecting rails and sleepers.

[0003] The bending, torsion and fatigue properties of the spring bars can be solved by selecting the corresponding steel grades and production processes, while corrosion resistance must be solved by anti-corrosion treatment of the spring bars.

[0004] Cold galvanizing is a method of surface corrosion protection for metal parts. It refers to the use of the rotation of the plating drum loaded with parts at room temperature to make the parts in the drum collide with each other and realize the mechanical energy transfer to form a coating. During the cold galvanizing process, the ω-shaped spring bars are easily hooked and entangled with each other due to the continuous rotation of the plating barrel, so that it is difficult to separate after galvanizing, and a lot of manpower is required to separate the spring bars. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the present invention proposes an anti-winding device for the cold galvanizing process of ω-shaped spring bars.

[0006] The technical solution adopted by the present invention to solve the technical problem is: an anti-winding device for the cold galvanizing process of ω-shaped spring bars, comprising a mesh sleeve with two ends respectively inserted into the two limbs of the spring bar to form a closed loop for the ω-shaped spring bar.

[0007] Furthermore, the diameters of the two ends of the mesh sleeve are 3 to 5 mm larger than the diameter of the raw material of the elastic bar.

[0008] Furthermore, the length of the mesh sleeve is not less than 90 mm.

[0009] Furthermore, the depth of the straight sections of the two limbs of the elastic bar penetrating into the net sleeve is greater than 10 mm.

[0010] Furthermore, the mesh sleeve adopts a structural type with large ends and a small middle.

[0011] Furthermore, after the two limbs of the spring bar penetrate into the net sleeve, the movable distance of the toe end of the spring bar in the net sleeve is 15 mm.

[0012] Furthermore, the mesh sleeve is made of a non-metallic material with good ductility and high toughness.

[0013] Furthermore, the wire diameter of the mesh is not less than 1 mm.

[0014] Furthermore, the mesh sleeve adopts a porous structure.

[0015] Compared with the prior art, the present invention has the following positive effects:

[0016] The present invention uses a mesh with strong ductility to penetrate the two limbs of the spring bar, so that the spring bar and the mesh form a closed loop, thereby solving the problem of the two limbs of the spring bar being hooked and entangled during the cold galvanizing process of the product. The specific advantages are as follows:

[0017] (1) The device of the present invention can effectively avoid the problem of entanglement of the two hooks of the ω-shaped spring clip during the cold galvanizing process.

[0018] (2) The device of the present invention avoids entanglement of products during the surface treatment process, and the products are easier to separate after cold galvanizing, thereby improving production efficiency and reducing labor costs.

[0019] (3) The present invention adopts a porous mesh structure, which can effectively avoid problems such as missing plating and uneven plating due to the elastic strip being wrapped. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will now be described by way of example with reference to the accompanying drawings, in which:

[0021] Figure 1 It is a schematic diagram of the structure of the present invention;

[0022] The reference numerals in the figure include: 1-net sleeve, 2-ω-shaped elastic bar. DETAILED DESCRIPTION

[0023] An anti-winding device for cold galvanizing process of ω-shaped spring bars, such as Figure 1 As shown, it includes: a net sleeve 1 and an ω-shaped elastic bar 2.

[0024] The two limbs of the ω-shaped elastic bar 2 penetrate into the two ends of the net sleeve 1 respectively, the penetration depth is greater than 10mm, and the movable distance between the two ends is 15mm.

[0025] The mesh sleeve 1 adopts a porous structure, which can ensure that various formulas of the elastic strip 1 are smoothly integrated with the product during the surface treatment process, avoiding problems such as missing plating of the product due to the wrapping of the mesh sleeve 1.

[0026] The mesh sleeve 1 adopts a structural type with large ends and a small middle, which can limit the movement of the two limbs of the elastic bar, ensuring that the mesh sleeve will not fall off or slide randomly on the elastic bar due to excessive movement displacement during surface treatment.

[0027] The mesh sleeve 1 is made of a material with good ductility and strong toughness, which can ensure that the mesh sleeve can be smoothly inserted into the ω-shaped elastic bar 2 and can be smoothly removed after surface treatment.

[0028] The mesh sleeve is made of non-metallic material with good ductility and high toughness.

[0029] The mesh sleeve aperture must be larger than the raw material diameter of the spring strip to ensure that there is sufficient clearance between the spring strip and the mesh sleeve, and the clearance value is usually (3-5) mm. This ensures that the plated medium is in full contact with the spring strip.

[0030] The length of the mesh should not be less than 90mm, and it is necessary to ensure that the length of the straight section of the elastic strip inserted into the mesh should not be less than 10mm.

[0031] The wire diameter of the mesh should not be less than 1mm to ensure it has sufficient strength.

[0032] The two ends of the net sleeve are respectively inserted into the two limbs of the elastic bar to form a closed loop, thereby preventing the two limbs of the elastic bar from being hooked and entangled with each other.

[0033] The working principle of the present invention is: the two limbs of the spring bar are restricted by the mesh sleeve, and the spring bar and the mesh sleeve form a closed loop, which effectively avoids the mutual entanglement of the product caused by the two limbs being exposed during the cold galvanizing process. In addition, the use of a porous mesh sleeve structure can effectively avoid problems such as missing plating and uneven plating due to the spring bar being wrapped.
