Description

Technical Field

[0001] The utility model relates to the technical field of sherardizing tooling, and more specifically, to a tooling for spring-bar sherardizing. Background Art

[0002] With the development of my country's high-speed railways, the number of rails has increased dramatically, and the problem of steel corrosion has become increasingly serious. According to surveys, the design life of most rails is 10 years, but due to corrosion, the actual life will be halved. The spring clip fasteners are designed to withstand huge instantaneous impact loads during the design stage, which puts high demands on the performance of the spring clips. However, they are easily damaged by bending, torsion, fatigue and corrosion, so the anti-corrosion of the spring clips has gradually been taken seriously.

[0003] At present, railway anti-corrosion mainly uses anti-corrosion grease and coating. However, the existing anti-corrosion grease has problems such as weak bonding, easy to fall off, and short life, and requires frequent maintenance. Grease is easy to secrete base oil outdoors, adhere to dust and sewage, and pollute the environment. Manual brushing of anti-corrosion grease is not only costly, but also uneven in quality and low in efficiency. In view of the importance of railway anti-corrosion issues, it is necessary to further study and explore more efficient anti-corrosion materials and coating methods. To this end, we seek an anti-corrosion technology with superior properties such as UV resistance, hydrophobicity, strong toughness, and high adhesion. In this regard, zinc infiltration anti-corrosion technology has been widely used at home and abroad due to its remarkable effects, and it deserves further attention and research.

[0004] For example, the authorization announcement number CN 215404461 U discloses a tool for spring-clip zinc infiltration, including a spring-clip frame and a spacer. The spring-clip frame includes a base plate, a penetration rod, a nut and an upper plate. Three penetration rods are arranged in a herringbone shape on the base plate, one in front and two in the back. Two supporting pads are symmetrically arranged on both sides of the front penetration rod in contact with the base plate. An external thread is arranged on the top of the penetration rod. The nut cooperates with the external thread on the top of the penetration rod and is screwed on the top of the penetration rod. Three through holes are arranged in a herringbone shape on the upper plate to allow the three penetration rods to pass through. The spacer includes a circular ring and two butterfly wings, and the butterfly wings are symmetrically arranged on both sides of the circular ring.

[0005] In the above, during the sherardizing process, the W-shaped spring bars are sequentially put on the wear rods. Due to the continuous rotation of the sherardizing furnace, the W-shaped spring bars are prone to mutual collision and entanglement, which results in serious bump marks on the surface of the W-shaped spring bars after sherardizing, and multiple W-shaped spring bars are entangled together. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model aims to provide a tool for zincizing spring bars, which will not cause mutual collision and entanglement between W-shaped spring bars and is convenient for placing and removing the W-shaped spring bars.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A tool for spring-clip zinc plating comprises a frame plate, which is hollow and has a plurality of longitudinally distributed plug-in slots on one side of the frame plate. A storage plate for placing W-shaped spring bars is provided in the plug-in slot, the storage plate extends into the plug-in slot, and the outer wall of the storage plate is movably connected to the inner wall of the plug-in slot. The storage plate is provided with a plurality of adjustment holes connected to the plug-in slot, and the storage plate is provided with two connecting rods for fixing the W-shaped spring bars. The connecting rods extend into the adjusting holes and are spirally connected to the adjusting holes so that the W-shaped spring bars are sleeved on the two connecting rods and connected to the connecting rods.

[0009] The utility model is further configured as follows: an external thread is arranged on the outer wall of the connecting rod, and an internal thread which is threadably connected to the external thread is arranged on the inner wall of the adjusting hole.

[0010] The utility model is further configured as follows: a support plate is provided on one side of the storage plate, and a pull ring is provided on the other side opposite thereto, and both the support plate and the pull ring are fixedly connected to the storage plate.

[0011] The utility model is further configured as follows: the support plate is provided with an embedded groove, the frame plate is provided with a convex strip extending into the embedded groove, and the convex strip is connected to the embedded groove.

[0012] By adopting the above technical solution, the beneficial effects of the utility model are:

[0013] Place the W-shaped spring bar on the storage plate, pass the two connecting rods through the two gaps of the W-shaped spring bar, extend them into the adjustment hole and rotate them so that the W-shaped spring bar is fixed on the storage plate and the two connecting rods, extend the storage plate into the plug-in slot, and the convex strip is fixed with the embedded slot, so as to facilitate the placement of the W-shaped spring bar. When the W-shaped spring bar is removed from the storage plate, it is only necessary to pull out the storage plate and rotate the two connecting rods out of the adjustment hole to take out the W-shaped spring bar. When the W-shaped spring bar is subjected to the zincizing treatment, since the W-shaped spring bar is placed separately

[0014] On the storage plate, the W-shaped spring bars will not collide or get entangled with each other, thus protecting the surface quality. BRIEF DESCRIPTION OF THE DRAWINGS
