Description

Technical Field

[0001] The utility model relates to the technical field of carbon press machines, in particular to a carbon press machine for cutting carbon green blanks at a fixed distance. Background Art

[0002] In the production process, a certain amount of paste is usually filled in the extrusion paste cylinder, and the green billet can be extruded into a very long length. Considering the fixed length dimensions of the actual graphite electrode blank, the extruded green billet needs to be divided into several equal sections at a fixed distance.

[0003] When the existing carbon press cuts graphite electrode green billets, it relies on manual visual operation to continuously extrude the green billets for fixed-distance cutting. At the same time, it is unable to ensure the cutting efficiency through its own structure and control method, resulting in different lengths of cut green billets and low cutting efficiency, which affects production costs.

[0004] Therefore, in view of the shortcomings of the prior art, it is necessary to provide a carbon press for cutting carbon green bodies at a fixed distance to solve the shortcomings of the prior art. Utility Model Content

Multiple rollers are movably installed inside the concave-shaped bracket through bearings. Graphite electrode green sheets are movably installed above the rollers. Two slide rails are fixedly installed above the concave-shaped bracket, and the slide rails are slidably connected to the U-shaped slider.

[0031] The utility model is further described in conjunction with the following embodiments.

[0032] Example 1.

[0033] like Figure 1-3 As shown, a carbon press for cutting carbon green bodies at a fixed distance comprises a carbon press body 1, a graphite electrode green body 2 is movably placed inside the carbon press body 1, and a bracket 3 is fixedly installed on one side of the carbon press body 1.

[0034] like Figure 1-3 As shown, a slide rail assembly 4 is installed above the bracket 3, and three groups of cutting mechanisms 5 are slidably installed above the slide rail assembly 4. The graphite electrode green body 2 passes through the slide rail assembly 4 and the cutting mechanism 5. A conveying mechanism 6 is fixedly installed on the cutting mechanism 5. The cutting mechanisms 5 are equidistantly arranged on the conveying mechanism 6, and a unloading mechanism 7 is installed on one side of the conveying mechanism 6.

[0035] By means of three groups of cutting mechanisms 5 equidistantly arranged on the conveying mechanism 6, during the process of continuous extrusion of green billets by the carbon press, relatively efficient fixed-distance cutting can be performed according to the discharge speed of the green billets, so that each green billet has an equal length.

[0036] like Figure 3 As shown, the cutting mechanism 5 includes two arc-shaped brackets 51, which are fixedly mounted on both sides of the conveying mechanism 6. A U-shaped slider 52 is installed on one side of the arc-shaped bracket 51, and a motor A 53 is installed on the other side of the arc-shaped bracket 51. The U-shaped slider 52 includes a U-shaped frame 57, which is fixedly mounted on the arc-shaped bracket 51. A circular slider 58 is installed at one end of the U-shaped frame 57 away from the arc-shaped bracket 51, and the circular slider 58 is slidably connected to the slide rail 43.

[0037] The cutting mechanism 5 equipped with the U-shaped slider 52 can achieve stable fixed-distance cutting according to the green billet discharging speed during the continuous extrusion of the carbon press to ensure the cutting efficiency and achieve equal length of each green billet.

[0038] like Figure 1-2 As shown, the motors A 53 are axially connected to the ball screws A 54, the ball screws A 54 are installed inside the U-shaped slider 52, the ball screws A 54 are connected to the top of the ball screws A 54, and a disc cutter 56 is installed between the two ball screw nuts A 55. The disc cutter 56 is a prior art and is not described in detail in this embodiment.

[0039] The transmission connection between the ball screw A 54 and the ball screw nut A 55 enables the disc cutter 56 to move smoothly in the vertical direction and cut the graphite electrode green body 2, so that the cutting section quality is high and the shear section misalignment is avoided.

[0040] like Figure 1-2 As shown, the slide rail assembly 4 includes a concave-shaped bracket 41, which is fixedly installed above the bracket 3. Ten rollers 42 are movably installed inside the concave-shaped bracket 41 through bearings. The graphite electrode green body 2 is movably installed above the rollers 42. Two slide rails 43 are fixedly installed above the concave-shaped bracket 41, and the slide rails 43 are slidably connected to the U-shaped slider 52.

[0041] The roller 42 movably connected in the slide rail assembly 4 can effectively reduce the friction between the graphite electrode green body 2 and the workbench when being extruded, so as to better protect the graphite electrode green body 2 from being damaged.

[0042] like Figure 2As shown, the conveying mechanism 6 includes a conveyor belt 61, and toothed belts 62 are fixedly installed on both sides of the conveyor belt 61. Two gear shafts 63 are connected to the toothed belt 62 for transmission. The motor B 64 drives the gear shaft 63 to drive the conveyor belt 61 to drive the cutting mechanism 5. During the process of continuous extrusion of green billets by the carbon press, the cutting speed can be followed to perform fixed-distance cutting, while ensuring the high quality of the cutting section, avoiding the occurrence of shear section staggering, and achieving equal length of each green billet.

[0043] like Figure 1 As shown, the unloading mechanism 7 includes a square base 71, on which two ball screws B72 are horizontally mounted, on which a motor C 73 is axially mounted, on which two ball screw nuts B 74 are mounted, and above which support columns 75 are mounted, the support columns 75 include a support column body 76, on which a Y-shaped baffle plate 77 is mounted.

[0044] The unloading mechanism 7 can automatically unload the graphite electrode green body 2 after cutting, making the overall device more efficient and stable.

[0045] In the present application document, the number of rollers 42 is set to ten, but the specific number of rollers 42 can be adjusted according to actual conditions and is not limited to ten. When the length of the graphite electrode green body 2 to be cut is longer, more rollers 42 can be used to ensure the structural stability of the device. The number of cutting mechanisms 5 is set to three, but the specific number of cutting mechanisms 5 can be adjusted according to actual conditions and is not limited to three. When the length of the graphite electrode green body 2 to be cut is smaller, more cutting mechanisms 5 can be used to ensure the structural stability of the device.

[0046] The utility model aims to avoid the deficiencies of the prior art and provide a carbon press for cutting carbon green billets at a fixed distance, comprising a carbon press body 1, a graphite electrode green billet 2 being movably placed inside the carbon press body 1, a bracket 3 being fixedly installed on one side of the carbon press body 1, a slide rail assembly 4 being installed above the bracket 3, a plurality of cutting mechanisms 5 being slidably installed above the slide rail assembly 4, the graphite electrode green billet 2 passing through between the slide rail assembly 4 and the cutting mechanism 5, a conveying mechanism 6 being fixedly installed on the cutting mechanism 5, the cutting mechanisms 5 being equidistantly arranged on the conveying mechanism 6, a discharging mechanism 7 being installed on one side of the conveying mechanism 6, the cutting mechanisms 5 being equidistantly arranged on the conveying mechanism 6 can be used to perform fixed-distance cutting in the process of continuously extruding green billets and discharging green billets by the carbon press following the green billet discharging speed, and at the same time, the working efficiency of cutting is ensured by its own structure and control method, so that the quality of the cutting section is high, the staggered shear section is avoided, the fixed-distance cutting efficiency is high, and the equal length of each green billet is achieved.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
