Description

Technical Field

[0001] The invention belongs to the technical field of graphite electrode processing, and in particular relates to a forming device for graphite electrode processing. Background Art

[0002] Graphite electrode forming is one of the key steps in the production process of graphite electrode. The mixed carbon paste is made into a green body (or green product) with a certain shape, size, density and strength under external action. The main forming methods of graphite electrode are as follows: extrusion forming, vibration forming, compression forming and isostatic pressing.

[0003] There are problems with the existing graphite electrode processing equipment:

[0004] Existing graphite electrode processing molding equipment, especially vibration molding equipment, has a problem that as the gaps between the particles of the heated carbon paste gradually shrink during the vibration process, the hot air accumulated inside the carbon paste cannot be discharged in time, causing the adhesive on the surface of the carbon paste to lose its viscosity due to overheating at high temperature. The carbon paste particles cannot be effectively bonded together, thereby affecting the strength and density of the electrode green body. Therefore, it cannot meet the existing use requirements of graphite electrode processing molding equipment. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the existing technology, the present solution provides a graphite electrode processing forming equipment that can increase the gap between the stacked paste particles and, combined with a negative pressure structure, can accelerate the discharge of hot air accumulated inside the paste particles.

[0006] The technical solution adopted in this scheme is as follows: This scheme proposes a forming equipment for graphite electrode processing, including a base, a bracket and a pad, the pad is arranged on the upper wall of the base, the bracket is symmetrically arranged on the upper wall of the base on both sides of the pad, the end of the bracket away from the base is provided with a feeding assembly, the upper wall of the feeding assembly is provided with a sieve assembly, the bottom wall of the feeding assembly is provided with an elastic assembly, the end of the bracket close to the base is provided with a guide assembly, the end of the guide assembly away from the bracket is provided with a bottom sealing assembly, and the end of the base close to the bracket is provided with a vibration driving assembly.

[0007] As a further preferred embodiment of the present invention, the feeding assembly includes an upper box body, a feed trough and a sealing plate. The upper box body is arranged at one end of the bracket away from the base, the upper box body is arranged with a bottom opening, the feed trough is arranged on the upper wall of the upper box body, the feed trough is a through setting, the sealing plate is arranged inside the feed trough, and the sealing plate is threadedly connected to the feed trough; the air sieve assembly includes an air sieve threaded hole, an air sieve rod, a threaded column, an air sieve spring, an air sieve frame, an air sieve mesh layer, an air pump and a pressure sensor, and the air sieve rod is arranged through the upper box body. The inner walls of both ends of the body, the threaded column is rotatably arranged on the upper wall of the sieve rod, the sieve frame is arranged on the bottom wall of the sieve rod, the sieve mesh layer is arranged between the sieve frames, the sieve spring is arranged between the upper box body and the sieve frame on the outside of the sieve rod, the air pump is arranged through the inner wall of one end of the upper box body, the pressure sensor is arranged on the side of the upper box body away from the air pump, the detection end of the pressure sensor is arranged through the inner wall of the upper box body, the sieve threaded hole is arranged on the upper wall of the upper box body outside the sieve rod, and the threaded column is threadedly connected to the sieve threaded hole.

[0008] When in use, the sieve air spring is normally in the compression setting, pressing the threaded column downward, and the threaded column uses the deformation of the sieve air spring to drive the sieve air rod to slide down along the inner wall of the upper box, and the threaded column drives the sieve air mesh layer away from the bottom wall of the upper box, and screws the threaded column into the sieve air threaded hole. The sieve air rod changes from an active state to a fixed state, and the sealing groove plate is rotated. The sealing groove plate is rotated out of the discharge chute, and the heated carbon paste is poured into the upper box through the discharge chute. The carbon paste falls into the inside of the sieve air mesh layer, and the carbon paste enters the upper section. After entering the box, the sealing plate is screwed into the lower chute to seal the upper box. The threaded column is rotated and unscrewed from the inside of the screen air threaded hole. The screen air spring elastically resets and drives the screen air mesh layer to rise through the screen air frame. The carbonaceous paste passes through the inside of the screen air mesh layer. The screen air mesh layer rises to be placed near the top wall of the upper box. The screen air mesh layer penetrates the carbonaceous paste, which makes the gap between the carbonaceous pastes larger, making it easier for the hot air accumulated inside the carbonaceous paste to be discharged, and avoiding the adhesive coated on the surface of the carbonaceous paste to fail at high temperature.

[0009] Preferably, the elastic assembly includes a buffer groove, a buffer spring and a middle section box body, the buffer groove is arranged on the bottom wall of the upper section box body, the buffer groove is opened at the lower end, the middle section box body is slidably arranged inside the buffer groove, the middle section box body is a cavity set through, and multiple groups of the buffer springs are arranged between the top wall of the buffer groove and the upper wall of the middle section box body; the guide assembly includes a guide groove and a guide rod, the guide groove is arranged at one end of the bracket close to the base, the guide groove is set through, and the guide rod is arranged on the inner wall of the guide groove.

[0012] When in use, the guide spring is in a compressed state. The bottom sealing slide uses the deformation of the guide spring to drive the bottom section box body away from the middle section box body. The bottom wall of the bottom section box body fits into the upper wall of the pad. The closing electromagnet is energized to generate magnetism. The closing electromagnet and the sliding magnet are set with the same pole. The closing electromagnet is fixed to the upper wall of the base and uses the repulsive force to push the sliding magnet under the deformation of the guide spring. The sliding magnet drives the bottom section box body to slide up along the guide rod through the bottom sealing slide plate. The end of the bottom section box body away from the sliding magnet enters the engaging groove at the bottom of the middle section box body, and the closing bolt is screwed into the bottom section box body to complete the splicing of the bottom section box body and the middle section box body.

[0013] Among them, the vibration driving assembly includes a motor box, a vibration motor, a vibration shaft, a connecting threaded hole, a vibration plate, a connecting bolt and a limit plate.

The vibration motor drives the vibration shaft through the vibration end, and the vibration shaft drives the bottom section box to vibrate up and down through the bottom sealing slide. The bottom section box uses the deformation of the buffer spring to drive the middle section box to slide along the buffer groove, thereby vibrating and forming the carbon paste.

[0043] A controller 36 is provided on the side wall of the upper section of the box body 5 on one side of the pressure sensor 16 .

[0044] The controller 36 is electrically connected to the air pump 15 , the pressure sensor 16 , and the vibration motor 31 , respectively.

[0045] During specific use, the sieve gas spring 12 and the guide spring 24 are both in a compressed state, the connecting bolt 35 is set away from the connecting threaded hole 33, the sieve gas rod 10 uses the deformation of the sieve gas spring 12 to drive the sieve gas mesh layer 14 to be placed close to the top wall of the upper box 5 through the sieve gas frame 13, and the bottom sealing slide 26 uses the deformation of the guide spring 24 to drive the bottom section box 27 away from the middle section box 20, and the bottom wall of the bottom section box 27 is in contact with the upper wall of the cushion block 3;

[0046] The controller 36 controls the closing electromagnet 37 to start, and the closing electromagnet 37 is energized to generate magnetism. The closing electromagnet 37 and the sliding magnet 38 are arranged with the same pole. The closing electromagnet 37 is fixed to the upper wall of the base 1. The closing electromagnet 37 uses the repulsive force to push the sliding magnet 38 under the deformation of the guide spring 24. The sliding magnet 38 drives the bottom section box 27 to slide and rise along the guide rod 23 through the bottom sealing slide 26. The end of the bottom section box 27 away from the sliding magnet 38 enters the engaging groove at the bottom of the middle section box 20, and the closing bolt 28 is screwed into the bottom section box 27, completing the splicing operation of the upper section box 5, the middle section box 20 and the bottom section box 27. The upper section box 5, the middle section box 20 and the bottom section box 27 form a forming cavity of the electrode;

[0047] Manually press the threaded column 11 downward, and the threaded column 11 uses the deformation of the sieve gas spring 12 to drive the sieve gas rod 10 to slide and descend along the inner wall of the upper box body 5, and the threaded column 11 drives the sieve gas mesh layer 14 away from the bottom wall of the upper box body 5, and screws the threaded column 11 into the sieve gas threaded hole 6. The sieve gas rod 10 changes from a movable state to a fixed state, and the sealing groove plate 8 is rotated. The sealing groove plate 8 is screwed out of the discharge chute 7. The discharge chute 7 is turned on, and the heated carbonaceous paste is poured into the upper box body 5 through the discharge chute 7. The carbonaceous paste falls into the molding cavity. After all the carbonaceous paste enters the molding cavity, the sealing groove plate 8 is screwed into the discharge chute 7 to seal the upper box body 5.

[0048] The upper wall of one end of the bottom sealing slide 26 away from the bottom section box 27 is in contact with the bottom wall of the limit plate 39. At this time, the connecting bolt 35 is coaxially and horizontally arranged with the connecting threaded hole 33. The connecting bolt 35 is rotated and screwed into the connecting threaded hole 33, so that the vibration shaft 32 is fixedly connected to the bottom sealing slide 26. The controller 36 controls the vibration motor 31 to start. The vibration motor 31 drives the vibration shaft 32 through the vibration end. The vibration shaft 32 drives the bottom section box 27 to vibrate up and down through the bottom sealing slide 26. The bottom section box 27 uses the deformation of the buffer spring 19 to drive the middle section box 20 to slide along the buffer groove 18, thereby vibrating the carbonaceous paste inside the molding cavity.

[0049] During the vibration of the carbon paste, a test threshold of the air pressure inside the molding cavity is pre-set by the pressure sensor 16, and the threaded column 11 is rotated. The threaded column 11 is unscrewed from the inside of the sieve threaded hole 6, and the sieve spring 12 elastically resets and drives the sieve mesh layer 14 to rise through the sieve frame 13, and the carbon paste passes through the inside of the sieve mesh layer 14. The sieve mesh layer 14 rises to be placed near the top wall of the upper box body 5, and the sieve mesh layer 14 penetrates the carbon paste, so that the gap between the carbon pastes becomes larger, which is convenient for the discharge of hot air accumulated inside the carbon paste, and avoids the failure of the adhesive coated on the surface of the carbon paste at high temperature. The controller 36 controls the vacuum pump 15 to start, and the vacuum pump 15 discharges the gas inside the molding cavity. The controller 36 controls the pressure sensor 16 to start, and the pressure sensor 16 monitors the gas pressure inside the molding cavity in real time. When the air pressure value inside the molding cavity drops to the threshold value preset by the controller 36, the controller 36 controls the vacuum pump 15 to stop;

[0050] After the carbonaceous paste inside the molding cavity is vibrated and formed, the controller 36 controls the closing electromagnet 37 to start, and the closing electromagnet 37 is energized to generate magnetism. The closing electromagnet 37 and the sliding magnet 38 are set with the same pole. The closing electromagnet 37 pushes the sliding magnet 38 through repulsion, and the sliding magnet 38 drives the bottom section box 27 to maintain an upward state. The closing bolt 28 is rotated, and the closing bolt 28 is screwed out of the bottom section box 27. The controller 36 controls the current entering the closing electromagnet 37 to decrease, and the magnetic field strength between the closing electromagnet 37 and the sliding magnet 38 gradually weakens. The bottom section box 27 slowly descends under the deformation reset of the guide spring 24, driving the formed electrode product to detach from the inside of the molding cavity. The bottom wall of the bottom section box 27 is in contact with the upper wall of the pad 3, completing the processing operation on the electrode; repeat the above operation when using it next time.
