Description

Technical Field:

[0001] The utility model relates to the field of metallurgy, and particularly to a mold for manufacturing an electrode shell. Background Art:

[0002] An electrode shell is a steel plate shell used for filling electrode paste in a self-baking electrode. As a mold for baking the electrode paste, it plays a role in shaping and protecting the electrode from oxidation during the baking process. In addition, the electrode shell also serves as a conductive component, which can bear most of the current when the electrode is not well baked, thereby improving the mechanical strength of the electrode.

[0003] During the manufacturing process of the electrode shell, several rib plates need to be inserted into the slots on the positioning plate first, and then twelve thin steels are welded to the outer end surfaces of the twelve rib plates, and finally the electrode shell is made. Due to the different furnace conditions of each calcium carbide furnace, the lengths of the rib plates welded inside the electrode shell are also different, so as to stabilize the stable transmission of current in the electrode baking and smelting processes of each calcium carbide furnace. Therefore, during the manufacturing process of the electrode shell, different electrode shells need to be manufactured according to different positioning plates to meet the production requirements.

[0004] Therefore, in the process of manufacturing the electrode shell with the existing positioning plate, it can only correspond to one furnace condition. Once the furnace condition changes, the electrode shell made by this positioning plate cannot ensure the stable transmission of current in the calcium carbide furnace. Content of the Utility Model:

[0005] The purpose of the utility model is to provide a mold for manufacturing an electrode shell to solve the problems raised in the above background art.

[0006] The utility model is implemented by the following technical solutions:

[0007] A mold for manufacturing an electrode shell includes two positioning plates and a connecting shaft connected between the two positioning plates; a plurality of slots are evenly opened on the positioning plate, and a clamping assembly is slidably arranged in each slot. The clamping assembly includes: a limit slider, a pressing plate, and a flange bolt; a rectangular groove and a threaded through hole are opened on the limit slider, the rectangular groove is perpendicular to the threaded through hole, a pressing plate is inserted into the rectangular groove, a through hole corresponding to the threaded through hole is opened in the middle of the pressing plate, and the flange bolt passes through the through hole and is threadedly connected with the threaded through hole, so that the pressing plate is fixedly clamped on the positioning plate.

[0008] Preferably, the structure of the limit slider is in an "I" shape.

[0009] Preferably, the structure of the pressing plate is in a "convex" shape.

[0010] Preferably, the center line is engraved on the outermost surface of the positioning plate.

[0011] Preferably, each slot of the positioning disk is provided with a scale value.

[0012] Advantages of the present utility model: By adjusting the position of the clamping assembly, ribs of different lengths are supported, so as to adapt to the production of different electrode shells, meet the requirements of various furnace conditions, and thus stabilize the stable transmission of current during the electrode baking and smelting processes of each calcium carbide furnace, improving the production efficiency and options for manufacturing electrode shells.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0019] Please refer to Figures 1-4 , the present utility model provides a technical solution for a mold for manufacturing an electrode shell:

[0020] A mold for manufacturing an electrode shell includes two positioning disks 1 and a connecting shaft 2 connected between the two positioning disks 1; twelve slots 1.1 are evenly opened on the positioning disk 1, and a clamping assembly is slidably arranged in each slot 1.1. The clamping assembly includes: a limit slider 3, a pressing plate 4, and a flange bolt 5; a rectangular slot 3.1 and a threaded through hole 3.2 are opened on the limit slider 3, the rectangular slot 3.1 is perpendicular to the threaded through hole 3.2, a pressing plate 4 is inserted into the rectangular slot 3.1, a through hole 4.1 corresponding to the threaded through hole 3.2 is opened in the middle of the pressing plate 4, and the flange bolt 5 passes through the through hole 4.1 and is threadedly connected to the threaded through hole 3.2, so that the pressing plate 4 is fixedly clamped on the positioning disk 1.

[0021] The limiting slider 3 is in an "I" shape structure, enabling the limiting slider 3 to be quickly installed and slide within the slot 1.1 on the positioning disk 1.

[0022] The pressing plate 4 is in a "convex" shape structure, and the protruding part just fits into the slot 1.1, making the force on both sides of the pressing plate 4 on the positioning disk 1 balanced.

[0023] The outermost surface of the positioning disk 1 is engraved with a center line, which is convenient for marking and positioning during the welding process.

[0024] Each slot 1.1 of the positioning disk 1 is provided with a scale value, which is convenient for directly adjusting the position of the clamping assembly according to the insertion length of the rib plate.

[0025] The working principle is as follows: According to the requirements of the furnace condition, the prepared rib plates are inserted into the slots 1.1, and then the clamping assembly is slid so that the upper surface of the limiting slider 3 abuts against the inner end face of the rib plate. At the same time, ensure that the outer end of the rib plate extends out of the circumferential surface of the positioning disk 1. Turn the flange bolt 5 to fix the clamping assembly so that the position of the rib plate remains unchanged after insertion. Then, weld twelve thin steels to the rib plate in sequence, and finally make an electrode shell.

[0026] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
