Description

Technical Field

[0001] This utility model belongs to the field of heat preservation electric furnace technology, specifically relating to a graphite electrode cutting device. Background Technology

[0002] Graphite electrodes are an indispensable component of holding furnaces. During operation, these electrodes suffer wear and tear, particularly at the non-end portions, resulting in a gourd-shaped structure—thicker at both ends and thinner in the middle. To prevent the lower part of the electrode from falling into the furnace, it's necessary to remove the electrode using an overhead crane when it reaches a certain wear level, cutting off the worn portion and the electrode section below it. Current technology typically involves manually cutting the electrode while it's still hot from the furnace, or by using an overhead crane to ram it against other equipment, causing it to break. This is because graphite electrodes are relatively soft at high temperatures and easily break. Cutting or breaking graphite electrodes will increase their hardness after cooling, making them more difficult to process. Furthermore, treating graphite electrodes at high temperatures allows them to be reused, while cooling will delay their use. However, manual cutting requires workers to wear heavy protective gear and use a sledgehammer to break the electrode, which is labor-intensive and dangerous. Using an overhead crane to break the electrode introduces too many uncertainties, making it impossible to cut at the precise location. Both manual and impact methods result in instability in the treatment of graphite electrodes, leading to uneven end faces and uneven discharge during use, thus affecting the operation of the holding furnace. Utility Model Content

[0003] This invention provides a graphite electrode cutting device to address the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A graphite electrode cutting device includes a base, on which four No. 1 columns are fixedly mounted. A No. 1 displacement mechanism is fixedly mounted on the upper end of the four No. 1 columns. A No. 2 displacement mechanism is fixedly mounted on the upper middle part of the four No. 1 columns. A movable clamp is fixedly connected to the movable part of the No. 1 displacement mechanism via a No. 1 fixed rod. A fixed clamp is provided opposite to the movable clamp. The fixed clamp is fixedly connected to a No. 1 horizontal bar via a No. 3 fixed rod. The two ends of the No. 1 horizontal bar are respectively fixedly connected to the upper ends of two No. 2 columns. The No. 2 columns are fixedly mounted on the base. A cutting blade is fixedly connected to the movable part of the No. 2 displacement mechanism via a No. 2 fixed rod.

[0006] Furthermore, a cutting support plate is provided directly opposite the cutting blade. The cutting support plate is fixedly connected to the second crossbar by the fourth fixing rod, and the second crossbar is fixedly connected between the two second columns.

[0007] Furthermore, an electric lifting platform is provided below the movable clamp and the fixed clamp to support the graphite electrode at different heights.

[0008] Furthermore, fixed baffles are connected to three of the upper surfaces of the electric lifting platform, and a movable baffle is connected to the remaining side.

[0009] Furthermore, the first and second displacement mechanisms have the same structure. The first displacement mechanism includes a first mounting base and a second mounting base, which are respectively fixed on two first columns on the same side. A lead screw is rotatably connected inside the first mounting base. The end of the lead screw away from the movable clamp passes through the first mounting base and is fixedly connected to the output shaft of the drive motor. The drive motor is fixedly mounted on the first mounting base. A guide rod is fixedly connected inside the second mounting base. A slider is provided between the guide rod and the lead screw. The slider is slidably connected to the guide rod and threadedly connected to the lead screw. The first and second fixed rods are respectively fixedly connected to the corresponding sliders.

[0010] Furthermore, a connecting beam is fixedly installed between the adjacent No. 1 and No. 2 columns to improve the overall rigidity of the cutting device.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This utility model clamps the graphite electrode by using a combination of a movable clamp and a fixed clamp, and drives the cutting blade to move through a second displacement mechanism, thereby cutting the graphite electrode from the designated part. This not only improves the cutting accuracy and the flatness of the cut surface, but also reduces the intensity of manual labor.

[0013] This utility model features an electric lifting platform to support the graphite electrode. The lifting height of the electric lifting platform can be controlled as needed, thereby aligning the cut part of the graphite electrode with the cutting blade and improving the accuracy of graphite electrode cutting.

[0014] This invention features a cutting support plate opposite the cutting blade, which ensures smooth cutting operations and improves the stability of the graphite electrode during the cutting process.

[0015] This utility model features a three-sided fixed baffle and an openable movable baffle on the upper part of an electric lifting platform. The fixed baffle and the movable baffle work together to collect the cut-off part, and the movable baffle can be opened to easily remove the cut-off part. Attached Figure Description
