Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal swing plating, in particular to an automatic swing plating device for stay bars. Background Art

[0002] Hot-dip galvanizing is an effective method for metal anti-corrosion, mainly used for metal structure facilities in various industries. It is to immerse the rust-removed steel parts into the molten zinc liquid at about 500 °C, so that the zinc layer adheres to the surface of the steel components, thereby achieving the purpose of anti-corrosion. The technological process of hot-dip galvanizing: finished product pickling - water washing - adding fluxing solution - drying - hanging plating - cooling - chemical treatment - cleaning - grinding - completion of hot-dip galvanizing. Hot-dip galvanizing has developed from the older hot plating method. Since it was applied in industry in France in 1836, it has a history of one hundred and forty years. However, the hot-dip galvanizing industry has developed on a large scale in the past thirty years along with the rapid development of hot-dip galvanizing by blowing and hanging plating.

[0003] At present, the processing form of stay bars is to draw black wire rod, cut off sections, roll threads at both ends, and then adopt the blowing plating process or the centrifugal swing plating process for galvanizing. According to the existing market demands and product characteristics, in addition to single cylindrical stay bars, there are many special-shaped stay bars in the market, such as bent stay bars or stay bars welded with connectors, etc. At present, the general stay bars rely on the blowing plating process for production. Limited by the workpiece characteristics, bent stay bars or special-shaped parts can only be produced by the centrifugal swing plating process. However, the current swing plating process equipment and tooling are simple (mainly relying on manual labor), and the output is low. The immersion zinc time cannot be effectively controlled, resulting in uneven zinc layer thickness.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model

[0005] In view of the above defects, the utility model provides an automatic swing plating device for stay bars to solve the problem of automatic swing plating of stay bars.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

Several sets of automatic clamping pliers groups are installed at the bottoms of the several sets of automatically moving vertical beams.

[0010] Furthermore, several sets of automatic clamping pliers groups respectively include a fixed frame, a fixed clamping jaw, an adjusting motor, an adjusting lead screw, an adjusting nut, a set of fixed slide rails, a sliding plate and a movable clamping jaw. The upper end of the fixed frame is installed at the bottom of the automatically moving vertical beam through a connecting flange. The fixed clamping jaw is installed on the left side of the bottom of the fixed frame. The adjusting motor is horizontally installed on the right side of the upper end of the fixed frame.

[0012] Furthermore, the rotating end of the driving motor is connected to the front rotating sleeve through a transmission belt.

[0013] Furthermore, several bearing plates are installed inside the zinc pot. Bearing grooves are respectively formed on the several bearing plates. A set of protective plates are installed on both sides of the upper end of the zinc pot.

[0014] The utility model provides a strip automatic plating device, which has the following beneficial effects. Through the cooperation of the automatic clamping pliers groups located at the bottoms of the two trusses and by automatically controlling the grasping time, the zinc dipping time of the strip is guaranteed. The clamping jaws can freely expand and contract according to the length of the strip to meet different length requirements. The automatic clamping pliers groups automatically pick up materials and automatically grasp the strip, seamlessly connecting with the horizontal centrifugal drum to realize centrifugal plating after hot dip galvanizing. By automatically controlling the time and rhythm, the surface of the workpiece is guaranteed to be smooth and the zinc layer is uniform and controllable.

[0015] While the centrifugal plating mechanism drives the horizontal centrifugal drum to rotate by means of a driving motor, the servo cylinder can make the horizontal centrifugal drum move back and forth, so that the strip can be fully plated by centrifugal force, preventing the phenomenon that the strip in the horizontal centrifugal drum is not thoroughly plated due to insufficient looseness.
