A graphite plug is a conical graphite rod like a plug. It is a cylinder made of graphite material. It is used to make high-voltage electrodes or large butt welding poles. It is widely used in industry, especially aluminum. Profile factory, used more. The graphite plugs produced by Liugong are made of high-quality isostatic graphite and are finely processed by CNC lathes, with high precision and durability.

Liugong has accumulated many years in the processing of graphite plugs. Graphite plugs and graphite plugs need to be turned during the processing, and most of the existing lathes are horizontal lathes and are not turned in a closed environment. , Because the graphite material is clamped horizontally in the turning process of the horizontal lathe, if the material is too long and the middle is turned too thin, plus the side impact of the turning tool on the material, the plug rod is sometimes easy to break from the middle part in the middle of processing, resulting in The whole workpiece is scrapped, and a large amount of graphite dust will be generated during the processing, which will cause harm to the workers’ bodies. Therefore, a vertical automatic fully enclosed turning facility is required to replace the defects and dust problems of horizontal lathes.

For the processing of graphite stopper, Liugong has developed a new type of graphite stopper fully enclosed processing facility to overcome the above defects. Using a cube-shaped frame, a square waste box is installed at the bottom of the frame, and a cylindrical waste box is installed in the center of the waste box. No. 1 servo motor and a square lower tray, a cylindrical screw rod is installed at each of the four corners of the inside of the frame, a disc-shaped synchronizing wheel is installed above each screw rod, and the four sprockets are composed of a ring The synchronous belt is connected, a square moving bracket is installed horizontally on the top of the four screw rods, a rectangular telescopic tool rest and a cylindrical No. 2 servo motor are installed on the bracket, a round hole is set in the center of the bracket, and the top of the rack is installed A cylindrical No. 3 servo motor is installed on the left side of the front, and a rectangular air cylinder is installed in the center of the top of the rack. Open the observation door, stand the graphite raw material on the lower tray, and control the cylinder to extend the piston rod to hold the graphite raw material and control the Brackets and telescopic turning tools for turning graphite raw materials.

According to Liugong Xu’s follow-up of customers for many years, the most eager demand of customers for graphite stoppers is: stronger anti-oxidation ability, so Liugong invested a lot of time and energy to develop an anti-oxidation integrated graphite stopper. , according to the component composition of mass percentage: artificial graphite is 25-28%, natural graphite is 25-28%, silicon carbide is 25-28%, and colloidal pitch is 16-25%; Made through the following steps: (1) pulverize artificial graphite, natural graphite and silicon carbide into powders respectively; (2) pour the artificial graphite, natural graphite, silicon carbide and colloidal pitch of step (1) into a mixer and mix evenly to form a mixture ; (3) extruding and truncating on the extruder to obtain the intermediate blank of the graphite plug rod; (4) roasting the intermediate blank of the graphite plug rod in a closed environment for 100-144 hours, and the control temperature is 800-1000 ℃, The semi-finished graphite stopper rod is finished; (5) the guide taper surface of the semi-finished graphite stopper rod is processed on a lathe, and that is done. The present invention uses pitch as a binder to improve the bonding strength of the graphite plug; by adding silicon carbide, the anti-oxidation ability is improved, and the service life of the graphite plug is increased to 480-720 hours.

Liugong produces graphite plugs, which are resistant to oxidation and durable, and have a long service life. Welcome to visit and use.
