Example Embodiment

[0022] The technical scheme of the present invention will be described in further detail below in conjunction with the drawings to make it easier to understand and grasp.

[0023] Such as figure 1 As shown, the present invention provides a polishing process for post-processing hot-dip galvanized products. A large number of steel balls 1 are placed in a accommodating cavity 2 that can rotate and vibrate up and down, and then the hot-dip galvanized product 4 to be processed Put it into the steel ball pile, start the equipment, and under the transmission of the moving rod 5, the containing cavity 2 rotates and vibrates up and down, prompting the hot-dip galvanized product 4 stored in it to collide and rub with the steel ball 1, so that the hot-dip galvanized product The surface of 4 is polished.

[0024] In order to achieve a good polishing effect, vertical grooves 3 can be uniformly arranged on the inner wall of the accommodating cavity 2, and the bottom of the accommodating cavity ...

Abstract

The invention relates to a post processing polishing process for a hot galvanizing product. The method comprises the steps of placing a large number of steel balls into a rotatable containing cavity capable of vibrating up and down, then placing the hot galvanizing product into the steel ball pile, starting equipment to rotate and vibrate the containing cavity up and down to promote the hot galvanizing product to be collided and rubbed with the steel balls, so the face of the hot galvanizing product is polished. The post processing polishing process for the hot galvanizing product can be implemented by adopting normal equipment, the operation is simple and convenient, the cost is very low, and the geometric dimension of a workpiece is not damaged in the treatment process. After the polishing, defects such bulges and uneven parts remaining at the face of the workpiece in a hot galvanized process can be removed, the face brightness of the workpiece is improved, the appearance quality of the workpiece is improved and the use demands of high-grade equipment are met.

Description

technical field [0001] The invention relates to a polishing process, in particular to a polishing process for post-processing hot-dip galvanized products. Background technique [0002] Hot-dip galvanizing, also known as hot-dip galvanizing, refers to melting zinc ingots at high temperature, then putting some auxiliary materials, and then dipping the metal structural parts into the galvanizing tank, so that a layer of zinc layer is attached to the metal parts. The advantage of hot-dip galvanizing is that it has strong anti-corrosion ability, and the adhesion and hardness of the galvanized layer are better. The hot-dip galvanizing process is mainly divided into the following steps: [0003] 1. Degreasing: chemical degreasing or water-based metal degreasing cleaning agent can be used to remove oil until the workpiece is completely soaked in water. [0004] 2. Pickling: H can be used 2 SO 4 15%, thiourea 0.1%, 40-60°C or pickling with HCL 20%, hexamethylenetetramine 1-3g / L,...
