Embodiment 1

[0016] Embodiment 1, the electrostatic powder spraying process that is used for carbon steel forging tool surface treatment

[0017] Firstly, the tools are polished and pre-treated by sand blasting to eliminate the surface oxide layer and oil stains, etc., and then the workpieces are hung on the rotatable device in the powder spraying room, and the distance between the workpieces is kept at 250-300mm.

[0018] Through the principle of air pressure, the uncharged green insulator in the powder cylinder-thermosetting epoxy resin mixed powder is charged with static electricity after being treated by an electrostatic generator (0-100KV). The manual spray gun of the device and the powder cartridge sprays the electrostatically charged mixed powder evenly onto the surface of the workpiece and absorbs it, and the scattered powder is recovered and processed by the recovery device. When spraying, rotate the rotating device in the spraying room to ensure that the workpiece to be sprayed c...

Embodiment 2

[0021] Embodiment 2, the electrostatic powder spraying process that is used for explosion-proof tool surface treatment

[0022] The surface treatment electrostatic powder spraying process of explosion-proof tools is basically the same as the surface treatment electrostatic powder spraying process and related process conditions of carbon steel forging tools. Or polishing treatment, so that the contact surface of the tool in the actual use process is the natural color of the metal, so as not to affect the explosion-proof performance of the tool itself. For example, the opening part of the open-end wrench and the planes on both sides of the wrench head should be polished, the inner diameter of the ring wrench needs to be processed by gold, and the ends on both sides need to be polished.

Abstract

The invention relates to a static powder spraying process for surface treatment of tools, comprising the following steps: 1, decontaminating the surface of the tool; 2, suspending the tool in a powder spraying chamber and carrying out static powder spraying on the tool; 3, standing for 2-3 minutes, feeding the tool in an oven, heating at 180-190 DEG C, insulating for 25-30 minutes, cooling and then discharging. The invention has the advantages that the operation is simple, the working environment is pollution-free, the treated tool surface has strong chemical resistance, scratch resistance, friction resistance, fire resistance, corrosion resistance and rust resistance, the treated tool can be stored for a long time and is convenient to transport, and the attractiveness of the tool surface is increased.

Description

technical field [0001] The invention relates to a tool surface treatment process, in particular to an electrostatic powder spraying process for the tool surface. Background technique [0002] At present, domestic explosion-proof tools generally do not undergo surface treatment, and are sold directly after polishing. The surface treatment of carbon steel forging tools generally adopts methods such as painting, bluing, blackening or electroplating. The paint spraying on the surface of the workpiece is generally carried out under natural conditions. Due to the low adhesion of the paint, the paint on the workpiece is easy to rub against each other and be impacted by external forces during use, thereby affecting the appearance of the product and shortening the anti-rust cycle; 1. The blackened workpiece, although it can play a rust-proof role in a short period of time (usually 2-3 months), it will still rust because the surface of the workpiece is prone to oxidation, and the act...
