Description

Technical Field

[0001] This utility model relates to the field of graphite electrode production and processing technology, specifically to an auxiliary limiting device for graphite electrode forming. Background Technology

[0002] Graphite electrodes are a type of high-temperature resistant graphitic conductive material made from petroleum coke and pitch coke as aggregates and coal tar pitch as binder through processes such as raw material calcination, crushing and grinding, batching, kneading, molding, baking, impregnation, graphitization, and machining. During the molding process of graphite electrodes, molding dies are used to extrude the raw materials into electrode blanks of specific shapes and sizes. In this process, it is necessary to limit the molding die to reduce the phenomenon of die displacement. Therefore, it is particularly important to develop an auxiliary limiting device for graphite electrode molding.

[0003] A reference announcement number CN216466406U describes an auxiliary limiting device for graphite electrode forming. This device includes a main body with an internally fixedly connected electric telescopic rod. A movable plate is fixedly connected to the bottom of the electric telescopic rod. An upper mold is located at the bottom of an extrusion rod. A motor is fixedly connected inside a production frame, and a threaded rod is movably connected inside the production frame. A first threaded block and a second threaded block are threadedly connected to the outer side of the threaded rod. A spring is fixedly connected to the upper part of a fixed plate. This auxiliary limiting device for graphite electrode forming uses a motor to drive the threaded rod to rotate, causing the first and second threaded blocks to move. The limiting plate then moves the placement plate, which in turn moves the upper mold via the electric telescopic rod. The spring buffers the extrusion pressure, allowing for rapid adjustment of the limiting range to meet the production needs of various graphite electrode types. However, while this device has good application potential, it is often inconvenient to move the lower mold away from the upper mold, making loading and unloading operations on the lower mold difficult and frequently causing problems for users. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary limiting device for graphite electrode forming, so as to solve the problem that although the device proposed in the background art can be applied well, it is usually not convenient to move the lower mold away from the lower mold, thus making it difficult to perform loading and unloading operations on the lower mold.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary limiting device for graphite electrode forming, comprising a worktable, a gantry frame fixed to the top of the worktable, two guide rails on one side of the gantry frame at the top of the worktable, a rail seat slidably mounted on the top of each guide rail, a bearing plate mounted on the top of each rail seat, an electric push rod mounted on the top of the worktable on the side of the bearing plate away from the gantry frame via a bracket, one end of the electric push rod being connected to the bottom end of the bearing plate, a control box mounted on the top of the worktable on the side of the electric push rod, the output end of a single-chip microcomputer inside the control box being electrically connected to the input end of the electric push rod, support frames on both sides of the top of the bearing plate, and a mounting plate mounted on the top of the two support frames.

[0006] Preferably, both sides of the inner side of the placement plate are provided with limiting grooves, and both ends of the limiting grooves extend to the outside of the placement plate. A bidirectional lead screw is rotatably installed on the inner wall between the support frames. Guide rods are fixedly installed on the inner walls of the support frames on both sides of the bidirectional lead screw.

The top of the limit clamp passes through the limit groove and extends to the top of the placement plate. The lower end of the limit clamp is movably connected to the guide rod. A lower mold is provided above the placement plate between the limit clamps. The lower mold is clamped and limited by the setting of the limit clamps.

The motor is configured to drive the bidirectional lead screw to rotate.

[0009] Preferably, a lifting cylinder is installed on one side of the top of the portal frame. The input end of the lifting cylinder is electrically connected to the output end of the microcontroller inside the control box. The bottom end of the lifting cylinder extends to the inner side of the portal frame and is provided with a fastening block.

[0012] (1) The bearing plate is driven to move horizontally by the electric push rod, so that the bearing plate drives the rail seat to slide on the top of the guide rail, so that the bearing plate drives the lower mold placed on the top of the placement plate to move horizontally smoothly, so as to move the lower mold away from the bottom of the upper mold, thereby making it easier to load and unload the lower mold, thus improving the convenience of using the auxiliary limiting device.

[0013] (2) By placing the lower mold on the top of the placement plate between the two limiting clamping plates, and then starting the motor to drive the bidirectional screw to rotate, the two limiting clamping plates slide towards each other on the outer walls of the bidirectional screw and the guide rod. When the two limiting clamping plates approach each other and fit against the outer walls of the two sides of the lower mold, the lower molds of different lengths can be clamped and limited, thereby improving the applicability of the auxiliary limiting device.

[0014] (3) By tightening the locking bolt, one end of the locking bolt is screwed out to the outside of the fastening block, and the fastening frame can be pulled down to remove it from the outside of the fastening block for disassembly of the upper mold. When the locking bolt is passed through the fastening frame and screwed into the outer wall of the fastening block, the fastening frame can be bolted and placed on the outside of the fastening block for installation of the upper mold, thus achieving the purpose of easy disassembly and replacement of the upper mold.

[0023] The fastening block 19 is provided with a fastening frame 18 on the outside. The inner walls of both sides of the lower end of the fastening frame 18 are provided with abutment blocks 20. The inner wall of the abutment block 20 contacts the outer wall of the fastening block 19. Locking bolts 21 are installed on both sides of the upper end of the fastening frame 18.

An upper mold 17 is installed at the bottom end of the fastening frame 18.

[0024] During use, the upper mold 17 can be disassembled and assembled by setting up related components such as locking bolt 21;

[0025] Two guide rails 5 are provided on the top of the workbench 1 on one side of the portal frame 2. A rail seat 6 is slidably installed on the top of each guide rail 5. A bearing plate 7 is installed on the top of the rail seat 6. An electric push rod 8 is installed on the top of the workbench 1 on the side of the bearing plate 7 away from the portal frame 2 through a bracket. One end of the electric push rod 8 is connected to the bottom end of the bearing plate 7. A control box 4 is installed on the top of the workbench 1 on the side of the electric push rod 8. The output end of the microcontroller inside the control box 4 is electrically connected to the input end of the electric push rod 8. Support frames 9 are provided on both sides of the top of the bearing plate 7. A placement plate 10 is installed on the top of the two support frames 9. Limiting grooves 16 are provided on both sides inside the placement plate 10. Both ends of the limiting grooves 16 extend to the outside of the placement plate 10. A double-acting screw 14 is rotatably installed on the inner wall between the support frames 9. Guide rods 15 are fixedly installed on the inner wall of the support frames 9 on both sides of the double-acting screw 14.

[0026] In use, the guide rod 15 is used to limit the movement range of the limiting clamp 12;

[0027] Limiting clamps 12 are threadedly installed on the outer walls of both sides of the bidirectional lead screw 14. The top of the limiting clamp 12 passes through the limiting groove 16 and extends to the top of the placement plate 10. The lower end of the limiting clamp 12 is movably connected to the guide rod 15. A lower mold 11 is provided above the placement plate 10 between the limiting clamps 12.

[0028] In use, the limiting clamp 12 is set to clamp and limit the lower mold 11;

The loading and unloading operations are performed. Then, the lower mold 11 is moved to the lower part of the upper mold 17. Subsequently, the lifting cylinder 3 is activated to drive the upper mold 17 to rise and fall. The lower mold 11 and the upper mold 17 can then work together to form the graphite electrode. Finally, by tightening the locking bolt 21, one end of the locking bolt 21 is screwed out to the outside of the fastening block 19. The fastening frame 18 can then be pulled down to remove it from the outside of the fastening block 19 to disassemble the upper mold 17. When the locking bolt 21 is passed through the fastening frame 18 and screwed into the outer wall of the fastening block 19, the fastening frame 18 can be bolted and placed on the outside of the fastening block 19 to install the upper mold 17. The upper mold 17 can then be replaced as needed, thus completing the use of the auxiliary limiting device.
