Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing surface treatment, in particular to a swinging flybar used in a chemical nickel plating processing line. Background Art

[0002] In the field of mechanical processing surface treatment, chemical nickel plating technology is favored because it can significantly improve the corrosion resistance and durability of the material surface. It is widely used in the processing of various materials such as steel, copper, bronze, aluminum and plastic. The core of this technology is to form a uniform and dense nickel coating on the surface of the substrate through chemical reaction to achieve the purpose of protecting the substrate and enhancing performance.

[0003] However, in the traditional chemical nickel plating process, a fixed flybar is often used to carry and move the workpiece into the processing tank. This type of flybar is usually designed as a single square beam with multiple suspension rods vertically arranged on it. The top of the suspension rod adopts a C-shaped bayonet design to facilitate the fixation of the workpiece, and the bottom is processed with a long waist hole to meet the installation requirements of the workpiece in different installation hole positions. Although this design meets the basic requirements of workpiece transportation to a certain extent, it exposes some significant problems in the specific application of chemical nickel plating.

[0004] First of all, the chemical nickel plating process requires that the bath liquid reagents be in full contact with the workpiece surface to ensure the uniformity and integrity of the coating. Since the bath liquid in the processing tank is often heated to a higher temperature to increase the activity of the reagents and the coating speed, a high temperature and high humidity environment is formed around the processing tank, accompanied by the release of nickel-containing vapors. These vapors are corrosive to a certain extent, which puts more stringent requirements on the processing environment of the equipment and the workpiece.

[0005] More importantly, when the workpiece is immersed in the bath, bubbles are easily formed on its surface, especially in the blind holes in the complex structure, due to the compression of gas. If these bubbles cannot be discharged in time, they will seriously hinder the full contact between the bath liquid and the inner wall of the blind hole, resulting in uneven coating thickness inside the blind hole, or even failure to form effective coating coverage, which directly affects the processing quality and final performance of the workpiece.

[0006] In view of the above problems, a swinging flybar for a chemical nickel plating processing line is proposed. Summary of the invention

[0007] In order to solve the above problems, the present invention provides a swinging flybar for a chemical nickel plating processing line. The swinging flybar for a chemical nickel plating processing line is driven by a pneumatic motor, has stronger environmental adaptability, does not need to reserve a power supply interface, and is safer and more reliable in an environment with high temperature and humidity. When working, a crane is used to place the swinging flybar with the workpiece installed in the guide seats on both sides of the corresponding processing groove, and the pneumatic motor is connected to the air source interface set on the side of the chemical nickel processing groove. The workpiece is driven by the pneumatic motor to reciprocate and swing up and down on the left and right sides. During the swinging process of the workpiece in the tank liquid, the bubbles in the blind holes on the surface of the workpiece will gradually break away from the blind holes, so that the tank liquid reagent is in full contact with the workpiece, thereby improving the plating quality of the workpiece.

[0008] The technical solution of the present invention is as follows: A swinging flybar for a chemical nickel plating processing line comprises a frame, a lifting and swinging mechanism, a rotating and swinging mechanism, a driving mechanism and a suspension rod. The lifting and swinging mechanism and the rotating and swinging mechanism are respectively arranged on both sides of the frame, the bottoms of the lifting and swinging mechanism and the rotating and swinging mechanism are respectively hinged with suspension rods, the workpiece is fixedly connected to the suspension rod, and the lifting and swinging mechanism and the rotating and swinging mechanism respectively drive the suspension rod to lift and swing and rotate and swing under the action of the driving mechanism.

The guide frame can be slidably installed on the frame in the vertical direction, and the swing frame is fixedly connected to the bottom of the guide frame, and the top of the suspension rod is hinged to the bottom of the swing frame.

[0012] A guide seat a and a guide seat b are installed opposite to each other on the frame, and guide blocks a and b are installed on the inner sides of the guide seats a and b respectively. Both sides of the guide frame cooperate with the guide blocks a and b respectively to slide along the vertical directions of the guide blocks a and b.
