Description

Technical Field

[0001] The invention relates to a tool, in particular to a hot-dip galvanizing tool for a suspension insulator iron cap. Background Art

[0002] At present, hot-dip galvanizing of iron caps is mostly done by pure manual operation, which has high labor intensity, poor working environment and cannot guarantee product quality. In addition, traditional hot-dip galvanizing of iron caps mostly uses vibration to remove excess zinc or zinc knocking to remove excess zinc, which does not completely remove excess zinc, resulting in a thick and uneven zinc layer and high zinc consumption. The special hanger for galvanizing iron caps with Chinese patent number CN102443751A only provides an iron cap hanger, which adopts mechanized hot-dip galvanizing. However, the hanger has a complex structure. Although it improves the automation level to a certain extent, the structure is too complicated, and the iron cap is shaped like a bowl. It is easy to accumulate dust and leak plating in the bowl of the iron cap, which has high requirements for galvanizing. The galvanizing effect of using this hanger is not ideal, and leak plating may occur, and the iron cap is inconvenient to take and install. Summary of the invention

[0003] In view of the problems existing in the above-mentioned prior art, the present invention provides a hot-dip galvanizing tool for the iron cap of a suspension insulator. The tool is used to fix the iron cap, facilitate hot-dip galvanizing, realize the automation of hot-dip galvanizing of the iron cap, facilitate the hanging and taking of the iron cap before and after hot-dip galvanizing, solve the problems of air pockets and leakage during hot-dip galvanizing of the iron cap, and facilitate the centrifugal process to throw out excess zinc liquid from the iron cap. Through structural design, the workpiece can be prevented from scattering and falling off during the galvanizing process.

[0004] The present invention provides a hot-dip galvanizing tooling for a suspension insulator iron cap, comprising: an outer tooling, an inner tooling, and an iron cap, wherein at least two iron caps are hung on the inner tooling;

[0005] The external tooling includes an upper flange, an intermediate flange, a vertical pole I and a bottom plate I; the upper flange is welded to one end of a plurality of vertical poles I, the bottom plate I is welded to the other end of a plurality of vertical poles I, the intermediate flange is fixedly mounted on the surface of the vertical pole I, and a plurality of waist-shaped holes are opened on the surface of the circular bottom plate I;

[0006] The inner tooling includes an upper cover plate, an intermediate support frame and a base. The upper cover plate is installed on the upper end of the base, and the intermediate support frame is installed in the middle of the base. The upper cover plate surface is provided with two symmetrical elliptical grooves I. The intermediate support frame is composed of a through rod I, a bottom plate II and a groove II. Several through rods I are evenly and equidistantly fixed around the bottom plate II. The bottom plate II surface is provided with two symmetrical elliptical grooves II. The base is composed of a clamping ring, a fixed tube, a supporting rod I, a supporting rod II, a vertical rod II, a stop rod, a through rod II, a bottom plate III and a supporting plate. The clamping ring is fixedly installed on the top of the fixed tube, and the end of the fixed tube is fixedly connected to the bottom plate III. A ring-shaped support plate is fixedly sleeved on the surface of the fixed tube, at least two symmetrical vertical rods II are welded on the surface of the support plate, a number of through rods II and at least two gear rods are evenly and equidistantly fixedly installed on the bottom plate III, a number of support rods I are respectively welded to the top of the gear rods, two symmetrical support rods II are fixedly installed on the surface of the fixed tube, the diameter of the groove I is equal to the diameter of the support rod II, the support rod II fixes the upper cover plate and does not shake, the diameter of the groove II is equal to the diameter of the gear rod, the through rod I forms an oblique angle with the bottom plate II, and the through rod II forms an oblique angle with the bottom plate III.

[0007] Preferably, a plurality of through holes are evenly and equidistantly opened on the surface of the intermediate flange. After the galvanizing is completed, the zinc liquid can flow out from the through holes without any residual zinc liquid, thus saving production costs.

[0008] Preferably, a V-shaped groove is provided on the outer circumference of the upper flange to facilitate grasping by a centrifugal gripper.

[0009] Compared with the related art, the hot-dip galvanizing tooling for the suspension insulator cap provided by the present invention has the following beneficial effects:

[0010] This tooling adopts an internal and external tooling structure. The external tooling is recycled in the galvanizing area without post-processing. The internal tooling can be recycled after post-processing. The internal tooling can be simply made and repeatedly galvanized to reduce energy loss. The external tooling is welded with round steel, which is beneficial to heat exchange and zinc ash discharge during hot-dip galvanizing. A waist-shaped hole is opened on the bottom plate of the external tooling, which cooperates with the protruding rod at the bottom of the internal tooling to prevent relative movement of the internal and external tooling during centrifugation, resulting in a better centrifugal effect. The internal tooling is made into a split structure, which is convenient for hanging and removing the iron cap. The internal tooling rod is tilted and forms a certain angle with the bottom plate, which is beneficial to the discharge of zinc ash inside the iron cap and prevents leakage plating. The internal tooling has a double-layer hanging structure to increase production. BRIEF DESCRIPTION OF THE DRAWINGS
