Description

Technical Field

[0001] The utility model relates to the technical field of carbon press machines, in particular to a carbon press machine for rapidly cutting and molding carbon green bodies. Background Art

[0002] Graphite electrodes are generally cylindrical products. The carbon extruder squeezes the carbon paste in the paste cylinder so that it is continuously formed and discharged from the press mouth. During the production process, a certain amount of paste is generally filled in the extrusion paste cylinder. The paste in the paste cylinder can be continuously extruded to produce very long blanks. Considering that the actual length of the graphite electrode blank is several fixed lengths, it is necessary to cut the extruded blank into several equal sections.

[0003] When the existing carbon press cuts graphite electrode blanks, the carbon press cannot synchronously follow the discharge speed during the continuous extrusion of the green blank to cut, and cannot ensure the cutting quality through its own structure and control method, resulting in low quality of the cut section and shear section staggered layers. At the same time, the cutting accuracy cannot meet the production technical requirements, which affects the cost increase.

[0004] Therefore, in view of the shortcomings of the prior art, it is necessary to provide a carbon pressing machine for quickly cutting and forming carbon green bodies to solve the shortcomings of the prior art. Utility Model Content

A cutting mechanism is installed on a sliding assembly, which can move along the axial direction of the material and cut along the radial direction of the material at the same time, ensuring that the carbon press can cut along the green billet discharge speed during the continuous extrusion of the green billet.

[0006] The above-mentioned purpose of the utility model is achieved through the following technical means.

A telescopic column is installed between the two hollow cams, and a disc cutter is installed on the telescopic column.

[0010] The sliding assembly includes two concave racks, which are fixedly installed under two U-shaped support frames respectively. Three double-sided bevel gears are transmission-connected to each concave rack. Every two double-sided bevel gears are axially connected to a motor B. The output shaft of motor B passes through the inside of the base and connects the two double-sided bevel gears. A support base is fixedly installed on motor B, and the support base is fixedly installed on both sides of the base.

[0011] The hollow cam comprises a cam body, an elliptical through hole is provided on the cam body, an annular rack is installed inside the elliptical through hole, the annular rack is meshed with the gear, and the annular rack drives and connects the gear.

[0042] like Figure 1As shown, the cutting mechanism 4 includes two U-shaped support frames 41, each of which can slide horizontally above the base 2 by installing a sliding component 3, and a motor A 42 is installed on the top of the U-shaped support frame 41. The motor A 42 can control the gear 43 connected to it, and the cutting quality of the graphite electrode green body 6 is controlled by electrically controlling the rotation direction of the gear 43 to ensure the cutting quality.

[0043] like Figure 1-2 As shown, the outside of the gear 43 is connected to the hollow cam 44 through transmission, and a telescopic column 45 is installed between the two hollow cams 44 to adjust the telescopic movement with the rotation of the hollow cam 44. A disc cutter 46 is installed on the telescopic column 45. The disc cutter 46 is a prior art and will not be described in detail in this embodiment. The cutting mechanism 4 can follow the extruded graphite electrode green billet 6 for cutting under the action of the sliding component 3.

[0044] like Figure 2 As shown, the feeding mechanism 5 includes a Y-shaped support frame 51, which is fixedly installed above the base 2. A plurality of rollers 52 are installed on one side of the Y-shaped support frame 51. A graphite electrode blank 6 is movably placed above the rollers 52 and the Y-shaped support frame 51. A tightening belt 53 is installed above the Y-shaped support frame 51 to lock the end of the graphite electrode blank 6 being cut.

[0045] like Figure 1 As shown, the sliding assembly 3 includes two concave racks 31, and the concave racks 31 are respectively fixedly mounted under the two U-shaped support frames 41. Three double-sided bevel gears 32 are transmission-connected to each concave rack 31, and every two double-sided bevel gears 32 are axially connected to a motor B 33.

[0046] The transmission connection between the double-sided bevel gear 32 and the concave rack 31 is electrically controlled by the motor B 33, so that the sliding assembly 3 can slide smoothly, and the cutting mechanism 4 can cut the green billet at the speed of the extruded green billet during the continuous extrusion of the green billet by the sliding assembly 3.
