Description

Technical Field

[0001] This utility model relates to the field of graphite electrode processing technology, specifically to a graphite electrode processing extrusion molding device. Background Technology

[0002] Graphite electrodes are widely used in high-temperature industrial fields such as electric arc furnace steelmaking and non-ferrous metal smelting, and their performance directly affects smelting efficiency and product quality. In the production process of graphite electrodes, extrusion molding is one of the key processes, directly affecting the electrode's density, strength, and dimensional accuracy.

[0003] Traditional graphite electrode extrusion molding devices often use manual or simple hopper direct feeding, which lacks an effective buffer and uniform feeding mechanism, easily causing uneven feeding and affecting the subsequent molding quality. Furthermore, when in use, the raw material enters the extrusion chamber directly. Due to the loose particles and poor flowability of the raw material, it is easy to cause large fluctuations in molding pressure and uneven density of the finished product, affecting product quality. Therefore, there is a need for a high-efficiency graphite electrode processing extrusion molding device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a high-efficiency graphite electrode processing extrusion molding device.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a graphite electrode processing extrusion molding device, including a support frame, an extrusion frame, a pretreatment frame and a buffer feeding mechanism;

[0006] A buffer feeding mechanism is set at the top of the support frame, the extrusion frame is set inside the support frame, and the pretreatment frame is set between the buffer feeding mechanism and the extrusion frame. The raw materials fall evenly into the pretreatment frame through the buffer feeding mechanism in sequence. The pretreatment mechanism in the pretreatment frame pre-extrudes the raw materials, and the pre-extruded raw materials fall into the extrusion frame.

[0007] A forming mold is connected to one side of the extrusion frame, and the spiral conveying mechanism inside the extrusion frame extrudes the raw material through the forming mold.

[0008] As an improvement, the support frame includes a square top frame, support legs, and support rods;

[0009] Support legs are provided at each corner of the bottom surface of the square top frame. The extrusion frame is fixed between the support legs by support rods and is located below the square top frame.

[0010] As an improvement, the buffer feeding mechanism includes a feeding frame and a vibration motor;

[0011] A fixed plate is provided at the top of one side wall of the support frame. After the vibration motor is fixed to the bottom surface of the fixed plate, the output end is connected to a feeding frame that extends to the top of the pretreatment frame, and the feeding frame is set at an angle.

[0012] As an improvement, a spring telescoping mechanism is also included;

[0013] A spring telescopic device is connected between the top surface of the support frame and the bottom outer wall of the feeding frame, and a pair of spring telescopic devices are mirrored.

[0014] As an improvement, the pretreatment mechanism includes pressure rollers;

[0015] Multiple pressure rollers are arranged and rotated in sequence within the pretreatment frame. Each pressure roller is driven to rotate by a motor. After the raw material falls into the pretreatment frame, it passes through the gap between adjacent pressure rollers and falls into the extrusion frame.

[0016] As an improvement, the screw conveyor mechanism includes a screw conveyor rod and a drive motor;

[0017] The spiral conveyor is horizontally rotated inside the extrusion frame, and one end is connected to a drive motor located on the outer wall of the extrusion frame. After the raw material is pre-extruded by the pretreatment mechanism, it falls into the extrusion frame and is then conveyed to the forming mold by the spiral conveyor for extrusion molding.

[0018] The advantages of this utility model compared with the prior art are as follows:

[0019] 1. The buffer feeding mechanism, consisting of a vibrating motor and a spring telescopic device, enables uniform and continuous conveying of raw materials, avoiding molding defects caused by uneven feeding;

[0020] 2. Multiple pressure rollers are set in the pretreatment frame to initially compact the raw material, improve its density and fluidity, and provide a good foundation for subsequent extrusion molding;

[0021] 3. The use of a spiral feeder to continuously transport raw materials, combined with the forming mold for extrusion molding, improves molding efficiency and product density uniformity, and reduces scrap rate. Attached Figure Description

[0029] A graphite electrode processing extrusion molding device, combined with an attached Figure 1-2 As shown, the system includes a support frame, an extrusion frame 1, a pretreatment frame 2, and a buffer feeding mechanism. The support frame includes a square top frame 4, support legs 5, and support rods 6. Support legs 5 are provided at each corner of the bottom surface of the square top frame 4. The extrusion frame 1 is fixed between the support legs 5 by the support rods 6 and is located below the square top frame 4. A buffer feeding mechanism is provided at the top of the support frame. The extrusion frame 1 is located inside the support frame, and the pretreatment frame 2 is located between the buffer feeding mechanism and the extrusion frame 1. The raw materials are evenly fed into the pretreatment frame 2 through the buffer feeding mechanism. The buffer feeding mechanism includes a feeding frame 7 and a vibration motor 8. A fixing plate 9 is provided at the top of one side wall of the support frame. The vibration motor 8 is fixed to the bottom surface of the fixing plate 9, and its output end is connected to the feeding frame 7 extending to the top of the pretreatment frame 2. The feeding frame 7 is inclined and also includes a spring telescopic device 10. A spring telescopic device 10 is connected between the top surface of the support frame and the bottom outer wall of the feeding frame 7. A pair of spring telescopic devices 10 are mirror images of each other.

[0030] The feeding frame 7 is connected to the support frame via the spring telescopic device 10. The vibration motor 8 is installed at the bottom of the fixed plate 9 to drive the feeding frame 7 to vibrate, so that the raw materials fall evenly into the pretreatment frame 2, avoiding blockage and material breakage.

[0031] Combined with appendix Figure 3 The pre-processing mechanism in the pre-processing frame 2 pre-extrudes the raw material, and the pre-extruded raw material falls into the extrusion frame 1. The pre-processing mechanism includes pressure rollers 11. Multiple pressure rollers 11 are provided and are arranged and rotated in the pre-processing frame 2. Each pressure roller 11 is driven to rotate by a motor. After the raw material falls into the pre-processing frame 2, it passes through the gap between adjacent pressure rollers 11 and falls into the extrusion frame 1.

[0032] The pretreatment frame 2 is set between the feeding mechanism and the extrusion frame 1. It has multiple parallel pressure rollers 11 inside. The pressure rollers 11 are driven to rotate by a motor. The raw material passes through the gap between the pressure rollers 11 and is initially compacted before entering the extrusion frame 1.

[0033] Combined with appendix Figure 4 A forming mold 3 is connected to one side of the extrusion frame 1. The spiral conveying mechanism inside the extrusion frame 1 extrudes the raw material through the forming mold 3. The spiral conveying mechanism includes a spiral conveying rod 12 and a drive motor 13. The spiral conveying rod 12 is horizontally rotatably arranged inside the extrusion frame 1, and one end is connected to the drive motor 13 located on the outer wall of the extrusion frame 1. After the raw material is pre-extruded by the pretreatment mechanism, it falls into the extrusion frame 1 and is conveyed to the forming mold 3 through the spiral conveying rod 12 for extrusion.

[0034] The spiral feed rod 12 is horizontally arranged inside the extrusion frame 1 and is driven to rotate by the drive motor 13 to transport the pre-treated raw material to the forming mold 3. The forming mold 3 is arranged on one side of the extrusion frame 1 and is connected to the end of the spiral feed rod 12. After the raw material is extruded through the mold, it forms a graphite electrode blank of the required shape.

[0035] In the specific implementation of this utility model, the graphite powder raw material is first added to the feeding frame 7, and the vibration motor 8 is started so that the raw material falls evenly into the pretreatment frame 2 through vibration. After the raw material enters the pretreatment frame 2, it is initially compacted through the gap between multiple pressure rollers 11 to improve its density and fluidity.

[0036] The compacted raw material enters the extrusion frame 1 and is continuously conveyed to the forming mold 3 by the spiral conveyor rod 12. The raw material enters the forming mold 3 under the push of the spiral conveyor rod 12 and is extruded through the mold to form a graphite electrode blank with a certain shape and size. The outlet of the forming mold 3 is equipped with a matching cooling and unloading device.
