Description

Technical Field

[0001] This utility model relates to the field of graphite electrode processing technology, and in particular to a graphite electrode tip grinding device. Background Technology

[0002] Graphite electrodes are a type of high-temperature resistant graphite conductive material made from petroleum coke and pitch coke as aggregates and coal tar pitch as binder. The process involves calcining raw materials, crushing and grinding them, batching, mixing, molding, baking, impregnation, graphitization, and machining. They are mainly used in electric arc furnaces to melt scrap steel or other raw materials to produce steel and other metal products. Their applications are very widespread, and grinding is required during the production and processing.

[0003] The existing grinding process for graphite electrodes has the following drawbacks: the grinding of graphite electrodes is divided into peripheral grinding and end grinding. Peripheral grinding is generally carried out directly by a special grinding machine, while end grinding is generally carried out by a hand-held grinding machine by a processing operator after the initial grinding. The end grinding process uses a common grinding disc structure, which results in very low grinding efficiency and a large amount of manual labor when processing the ends of graphite electrodes. Therefore, we propose a graphite electrode end grinding device. Utility Model Content

[0004] The main purpose of this utility model is to provide a graphite electrode tip grinding device. Through the grinding mechanism set on the surface of the mounting plate, the graphite electrode tip can be quickly and efficiently ground, improving efficiency, reducing manual labor, and effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A graphite electrode tip polishing device includes a base, a mounting plate, and a polishing mechanism. The mounting plate is inserted into the top of the base, and the polishing mechanism is provided on the surface of the mounting plate. The polishing mechanism includes a drive shaft, a motor, pulleys, a drive belt, a tapered sleeve, and a polishing strip. The drive shaft is horizontally mounted inside the mounting plate, and the motor is horizontally mounted on one side of the mounting plate. The power output end of the motor and the outer periphery of the drive shaft are both equipped with pulleys located inside the mounting plate, and the pulleys are connected to each other by a drive belt. The power output end of the drive shaft extends to one end outside the mounting plate and is detachably connected to a tapered sleeve that matches the specifications of the graphite electrode tip. A polishing strip is detachably connected to the inner wall of the tapered sleeve.

[0007] Furthermore, it also includes an adjustment mechanism. An adjustment mechanism is provided at the connection between the base and the mounting plate. The adjustment mechanism includes a slot, a horizontal plate, a screw hole, a screw rod, and a connecting ring. A slot is vertically opened on one side of the base, and the bottom of the mounting plate is inserted into the slot. A horizontal plate is fixedly connected inside the slot. A screw hole is opened inside the horizontal plate, and a screw rod is screwed into the screw hole. A connecting ring located at the bottom of the mounting plate is installed at the top of the screw rod. The bottom of the mounting plate is inserted into the slot inside the base. The bottom of the mounting plate and the horizontal plate are connected by a screw rod. Before grinding the end of the graphite electrode, the screw rod is turned according to the overall height of the graphite electrode placement frame. When the screw rod is turned, the connecting ring rotates inside the mounting plate, so that the screw rod can drive the vertical height adjustment of the mounting plate, so that the conical sleeve at its processing end is aligned with the end of the graphite electrode, which facilitates processing and adapts to placement frames of different heights.

[0008] Furthermore, a connecting plate is provided at one end of the power output end of the drive shaft outside the mounting plate. The connecting plate and the end of the tapered sleeve are both provided with corresponding mounting holes. The specifications of the tapered sleeve can be selected according to the end specifications of the graphite electrode. When installing a suitable tapered sleeve, its end is attached to the surface of the connecting plate, and the mounting holes are aligned and fasteners are screwed in to fix the position of the tapered sleeve.

[0009] Furthermore, a control switch is provided on one side of the mounting plate surface, and the motor current input terminal is connected to the external power supply terminal through the control switch; the operation of the entire device is controlled by the control switch.

[0010] Furthermore, a limiting groove is vertically formed on one side of the inner wall of the slot, and a limiting block is installed at the bottom of the outer wall of the insert plate, which is inserted into the limiting groove; through the cooperation of the limiting groove and the limiting block, the movement adjustment of the mounting plate is further limited.

[0011] Compared with the prior art, this utility model has the following advantages: The top of the base is provided with a mounting plate, and the grinding mechanism is set on the surface of the mounting plate. The conical sleeve adopts a specification corresponding to the size of the graphite electrode end, and its interior has a grinding strip structure. After the outer circumference of the graphite electrode is ground, it is placed on the top of the placement rack. At this time, the base is moved to the graphite electrode end, aligning the end of the conical sleeve with the graphite electrode end. The motor is turned on, and the motor drives the conical sleeve and its internal grinding strip to rotate through the cooperation of pulleys, transmission belts, and transmission shafts. During the rotation, the base moves towards the graphite motor side until the conical sleeve is completely fitted onto the outer circumference of the graphite electrode end. During the process, a high-speed rotating grinding wheel structure is used to grind the end of the graphite electrode, improving grinding efficiency and reducing the workload of processing personnel. The bottom of the mounting plate is inserted into the slot inside the base. The bottom of the mounting plate is connected to the horizontal plate by a screw. Before grinding the end of the graphite electrode, the screw is turned according to the overall height of the graphite electrode placement rack. When the screw is turned, the connecting ring rotates inside the mounting plate, so that the screw can drive the vertical height adjustment of the mounting plate, so that the conical sleeve at the processing end is aligned with the end of the graphite electrode, which facilitates processing and adapts to placement racks of different heights.

The polishing strip 307 is detachably connected to the inner wall of the conical sleeve 306.

[0018] The system also includes an adjustment mechanism 4. An adjustment mechanism 4 is provided at the connection between the base 1 and the mounting plate 2. The adjustment mechanism 4 includes a slot 401, a horizontal plate 402, a screw hole 403, a screw rod 404, and a connecting ring 405. A slot 401 is vertically formed on one side of the base 1, and the bottom of the mounting plate 2 is inserted into the slot 401. A horizontal plate 402 is fixedly connected inside the slot 401. A screw hole 403 is formed inside the horizontal plate 402, and the screw rod 404 is screwed into the screw hole 403. A cap located inside the mounting plate 2 is mounted at the top of the screw rod 404. The bottom connecting ring 405; the bottom of the mounting plate 2 is inserted into the slot 401 inside the base 1. The bottom of the mounting plate 2 is connected to the horizontal plate 402 by a screw 404. Before grinding the end of the graphite electrode, the screw 404 is turned according to the overall height of the graphite electrode placement frame. When the screw 404 is turned, the connecting ring 405 rotates inside the mounting plate 2, so that the screw 404 can drive the vertical height adjustment of the mounting plate 2, so that the conical sleeve 306 at the processing end is aligned with the end of the graphite electrode, which is convenient for processing and adapts to placement frames of different heights.

[0019] The drive shaft 301 has a connecting plate 305 located at one end outside the mounting plate 2.

The motor 302 drives the conical sleeve 306 and its internal grinding strip 307 to rotate through the cooperation of the pulley 303, the transmission belt 304 and the transmission shaft 301. During the rotation, the base 1 is moved towards the graphite motor 302 until the conical sleeve 306 is completely fitted into the graphite electrode. During the insertion process, the outer periphery of the electrode end is polished using a high-speed rotating grinding wheel 307 structure, which improves polishing efficiency and reduces the workload of processing personnel. The bottom of the mounting plate 2 is inserted into the slot 401 inside the base 1. The bottom of the mounting plate 2 is connected to the horizontal plate 402 by a screw 404. Before polishing the end of the graphite electrode, the screw 404 is turned according to the overall height of the graphite electrode placement frame.
