Description

Technical Field

[0001] This utility model relates to the field of graphite block clamping technology, specifically an adjustable clamp for graphite blocks in an internal graphitization furnace. Background Technology

[0002] The internal graphitization furnace is a core piece of equipment in the carbon industry for the production and processing of graphite cubes. The precision of the loading process directly affects the final quality of the graphite cubes. When loading graphite cubes, a specific spacing must be maintained between adjacent cubes according to the process requirements. This spacing is crucial for ensuring uniform graphitization and smooth heat transfer, preventing problems such as cracking and uneven performance caused by localized overheating or incomplete reaction. Therefore, specialized tooling is needed to achieve precise clamping and spacing control of the graphite cubes, ensuring that the loading process meets process standards.

[0003] Traditional graphite square loading fixtures can only meet the clamping requirements of single or multiple graphite squares, but cannot directly form the required spacing during the clamping stage. After loading, the gaps between graphite squares must be manually adjusted one by one, which is not only cumbersome, time-consuming, and labor-intensive, significantly reducing loading efficiency, but also makes it difficult to ensure uniform spacing, and is prone to deviation of process parameters due to human error. In addition, traditional fixtures lack stable limiting and buffering structures, and graphite squares are prone to slippage, displacement, or surface damage during clamping, which affects the safety of the loading operation and also has an adverse effect on the product quality of the graphite squares. To address this, we propose an adjustable clamp for graphite squares in the loading of an internally serial graphitization furnace. Utility Model Content

[0020] 1. The adjustable clamp for loading graphite squares into the internal graphitization furnace, with the adjusting block at the bottom of the clamping support member slidingly engaging with the adjusting shaft and the movable groove of the adjusting block, can flexibly adapt to the spacing requirements of different processes for graphite squares. During loading, the adjusting block is placed between two graphite squares, and with the clamping limit of the first and second clamping rotating parts, the required gap is directly formed, completely eliminating the step of manually adjusting the gap after loading the furnace using traditional tooling, significantly reducing labor costs and operation time. At the same time, the telescopic coordination between the adjusting plate and the adjusting storage frame, through the connecting rod connecting seat, drives the clamping drive connecting rod, which drives the clamping rotating part to accurately realize the opening and closing of the adjusting clamp, so that the synchronous clamping and positioning of multiple graphite squares can be completed at one time, making the operation process simpler and more efficient.

[0021] 2. The adjustable clamp for the graphite cube in the internal graphitization furnace has increased contact friction with the graphite cube due to the toothed protrusions at the front end of the clamp and both ends of the adjusting block, effectively preventing the graphite cube from slipping or shifting during clamping. The cross-symmetrical bending structure of the first and second clamping rotating parts, combined with the rotating shaft connection in the rotating part placement slot, makes the clamping force distribution more uniform and reduces damage to the graphite cube during clamping. In addition, the double suspension structure composed of the support connecting ring and the lifting ring, combined with the rotatable design of the lifting ring, is adapted to the angle adjustment during the furnace loading process. The fixing group composed of the positioning block, auxiliary parts and auxiliary springs makes the connection between the adjusting storage frame and the support fixing plate firm, improving the overall stability and service life of the clamp.

[0065] Working Principle: In the overall assembly and suspension support stage, the adjusting storage frame 5 serves as the core load-bearing structure. Its hollow inner design provides vertical sliding space for the adjusting plate 4. The connecting rod connecting seats 17 on both sides of the bottom end of the adjusting plate 4 pass through the bottom end of the adjusting storage frame 5 and form a telescopic fit. The sleeves at both ends of the connecting rod connecting seats 17 ensure the stability of the telescopic process. The lifting ring fixing part 3 at the top of the adjusting plate 4 is bolted to install symmetrical lifting rings 2. The top of the lifting ring 2 is circular. The inner side of the bottom of the supporting connecting ring 1 fits against the inner side of the circular ring of the lifting ring 2, forming a double suspension structure. This ensures the overall suspension stability of the fixture and allows the rotatable design of the lifting ring 2 to adapt to the angle adjustment requirements during the furnace loading process. The cooperation between the fixing group and the supporting connecting cylinder 6... The key fixing mechanism consists of a positioning block 7 fixed to the top center of the support fixing plate 10, with symmetrical auxiliary parts 8 installed in its internal fixing cavity. Multiple auxiliary springs 9 on the back of the auxiliary parts 8 provide elastic support, forming a complete ring on the inner front side of the two auxiliary parts 8. The support connecting cylinder 6 at the bottom of the adjustable storage frame 5 is inserted into the positioning block 7 through a connecting cylinder fixing ring 18. The ring formed by the auxiliary parts 8 is fitted onto the top of the connecting cylinder fixing ring 18, and the bottom end of the auxiliary parts 8 is in contact with the top end of the connecting cylinder fixing ring 18. Under the elastic action of the auxiliary springs 9, a tight fixation is achieved, ensuring the firmness of the connection between the adjustable storage frame 5 and the support fixing plate 10. Adjustment block movable grooves 20 are opened at the bottom ends of the clamping support parts 11 at both ends of the support fixing plate 10. The adjusting shaft at the top of the adjusting block 12 is embedded in the movable groove and forms a sliding fit, allowing the position of the adjusting block 12 to be adjusted according to the required spacing of the graphite squares. The rotating part placement groove 19 at the top of the clamping support 11 is connected to the first clamping rotating part 14 and the second clamping rotating part 15 via a rotating shaft. The two have a cross-symmetrical bent structure, and the rotating connection hole at the bend engages with the rotating positioning hole of the rotating part placement groove 19 to achieve flexible rotation. An adjusting clamp 13 is installed on the inner side of one end of the first clamping rotating part 14 and the second clamping rotating part 15. The front end of the adjusting clamp 13 and the toothed protrusions at both ends of the adjusting block 12 enhance the friction with the graphite squares and ensure clamping stability. The other ends of the two are connected to the clamping drive linkage 16 via a connecting rod shaft. The other end of the clamping drive linkage 16 is sleeved on the sleeve of the linkage connecting seat 17 and forms a rotatable connection. By pulling the support connecting ring 1 upward by external force, the adjusting plate 4 moves up and down. The clamping drive linkage 16 is driven by the linkage connecting seat 17, which in turn drives the first clamping rotating part 14 and the second clamping rotating part 15 to rotate around the rotation axis, realizing the opening and closing action of the adjusting clamp 13. When loading the furnace, the adjusting block 12 is placed between the two graphite squares. With the clamping force of the clamping rotating part and the limiting effect of the adjusting block 12, a gap that meets the process requirements is directly formed without subsequent manual adjustment, which greatly improves the furnace loading efficiency. Through the linkage and cooperation of each component, the integrated operation of graphite square clamping, gap adjustment and stable fixation is realized.
