The driving rod moves horizontally so that the first sliding rod and the second sliding rod slide back and forth inside the second slide groove, so that the grinding block and the coating sponge block move back and forth horizontally. Due to the reciprocating horizontal movement of the grinding block, the straightened steel bar enters the grinding hole to grind and remove rust on the surface of the steel bar. Then, when the ground steel bar enters the coating hole When covering the inside of the hole, the surface of the steel bar is coated with an anti-corrosion agent by moving the coating sponge back and forth, so as to prevent rust on the surface during subsequent use or storage. Grinding can remove burrs, rust and dirt on the surface of the steel bar, making the surface of the steel bar smoother and flatter, which not only helps to improve the appearance of the steel bar, but also reduces the wear and corrosion caused by the uneven surface during use. The surface of the steel bar after grinding is rougher, which helps to increase the contact area and adhesion between the anti-corrosion agent and the surface of the steel bar. The anti-corrosion agent can fit more closely on the surface of the steel bar to form a solid protective layer, thereby improving the anti-corrosion performance of the steel bar.
