Description

Technical Field

[0001] The utility model relates to the technical field of graphite electrode butt joint devices, and specifically relates to an automatic graphite electrode butt joint test device. Background Art

[0002] A graphite electrode refers to a high-temperature resistant graphite conductive material made of petroleum coke and pitch coke as aggregates, coal tar pitch as a binder, through processes such as raw material calcination, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization, and machining. The electrode head of a graphite electrode is generally a threaded head with a threaded groove on the outside. When using a graphite electrode, the threaded head of one graphite electrode needs to be screwed into the threaded groove of another graphite electrode to complete the butt joint installation. As a conductive material in electric furnace smelting, the consumption of graphite electrodes is proportional to the consumption of electricity. During smelting work, different specifications of graphite electrodes are used according to the size of the electric furnace, and as the electrodes are continuously consumed in the electric furnace smelting, the electrodes need to be continuously lengthened.

[0003] When producing graphite electrodes, a threading comb cutter is needed to process the graphite electrodes to achieve the butt joint of two graphite electrodes; after replacing the threading comb cutter, a butt joint test needs to be carried out to ensure that the product quality meets the process technical requirements. The traditional butt joint test device uses manual operation, and the butt joint test is carried out by manual rotation. Each time a graphite electrode butt joint test is done, at least 4 to 5 people are required to cooperate to complete it. The labor cost is high, the labor intensity is large, and the butt joint efficiency is low. Therefore, we propose an automatic graphite electrode butt joint test device. Content of the Utility Model

[0004] The technical problem to be solved by the present utility model is to overcome the existing defects and provide an automatic butt-joint test device for graphite electrodes. When in use, the graphite electrode with a threaded hole is clamped and fixed by a clamping component, and the end of the graphite electrode with the threaded hole faces inward. At the same time, the graphite electrode with a threaded head is placed between the first runner and the auxiliary runner on the working plate, and the end of the graphite electrode with the threaded head faces the threaded hole of another graphite electrode. Then, the driving component operates to drive the second rotating shaft to rotate. The rotation of the second rotating shaft drives the second bevel gear to rotate. The rotation of the second bevel gear drives the first bevel gear to rotate. The rotation of the first bevel gear drives the fifth rotating shaft to rotate. The rotation of the fifth rotating shaft drives the first sprocket to rotate. The rotation of the first sprocket drives the second sprocket to rotate under the action of the chain. The rotation of the second sprocket drives the fourth rotating shaft to rotate. The rotation of the fourth rotating shaft drives the first runner to rotate. The rotation of the first runner can drive the graphite electrode in contact with it to rotate. The auxiliary runner will rotate following the rotation of the graphite electrode. The two first runners and the two auxiliary runners can ensure the stability of the graphite electrode during rotation. At the same time, the rotation of the first bevel gear also drives the third bevel gear to rotate. The rotation of the third bevel gear drives the third rotating shaft to rotate. The rotation of the third rotating shaft drives the second runner to rotate. Thus, the second runner drives the graphite electrode in contact with it to move towards the direction of another graphite electrode. Furthermore, the graphite electrode with a threaded head can not only move horizontally but also rotate, so that the graphite electrode with a threaded head can be automatically screwed into the graphite electrode with a threaded hole. Such a setting not only improves the efficiency and effect of the automatic butt-joint of graphite electrodes, but also reduces the labor intensity of workers, effectively avoids time-consuming and laborious work, and can effectively solve the problems in the background technology.

[0005] To achieve the above object, the present utility model provides the following technical solution: An automatic butt-joint test device for graphite electrodes, comprising a bottom plate, a chain, a clamping component and a driving component;

The other end of the threaded rod is rotatably installed with a movable arc plate. A slider is installed on the lower surface of the movable arc plate. A chute is formed on the upper surface of the working plate. The slider is slidably connected to the chute. By rotating the handle to drive the threaded rod to rotate, the threaded rod rotates and drives itself to move under the action of the mounting bracket, the slider and the chute. The movement of the threaded rod itself drives the movable arc plate to move, so as to adjust the distance between the movable arc plate and the fixed arc plate, and clamp the graphite electrode with a threaded hole placed between the movable arc plate and the fixed arc plate.

[0008] Further, the driving assembly includes a motor bracket installed on the upper surface of the bottom plate. A motor is installed on the motor bracket. The output shaft of the motor is connected to one end of the second rotating shaft through a coupling. The input end of the motor is electrically connected to the output end of an external controller. By controlling the motor to work through the external controller, the motor works to drive the second rotating shaft to rotate, so as to automatically complete the docking work of the two graphite electrodes electrically.

[0019] The working principle of a graphite electrode automatic docking test device provided by the present utility model is as follows: When in use, the graphite electrode with a threaded hole is clamped and fixed by a clamping component, and the end with the threaded hole of the graphite electrode faces inward. At the same time, the graphite electrode with a threaded head is placed between the first rotating wheel 15 and the auxiliary rotating wheel 20 of the working plate 4, and the end with the threaded head of the graphite electrode faces the threaded hole of another graphite electrode. Then, the driving component operates to drive the second rotating shaft 12 to rotate. The rotation of the second rotating shaft 12 drives the second bevel gear 11 to rotate.

By rotating the handle 23 to drive the threaded rod 22 to rotate, the rotation of the threaded rod 22 drives the threaded rod 22 itself to move under the action of the mounting bracket, the slider and the chute 21. The movement of the threaded rod 22 itself drives the movable arc-shaped plate 27 to move, thereby adjusting the distance between the movable arc-shaped plate 27 and the fixed arc-shaped plate 18 to clamp the graphite electrode with a threaded hole placed between the movable arc-shaped plate 27 and the fixed arc-shaped plate 18. By controlling the operation of the motor 6 through the external controller, the motor 6 drives the second rotating shaft 12 to rotate, thereby automatically completing the docking work of two graphite electrodes electrically.
