Description

Technical Field

[0001] This utility model relates to the field of alloy production technology, and more specifically, to a boat-and-dish structure with a mortise and tenon joint. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] Due to the special processing environment, cemented carbide inserts require a smooth and flat surface without defects to ensure strong adhesion after coating. High-quality cemented carbide has a uniform and dense internal and external structure, a smooth surface, and is free from defects such as cracks, bubbles, pits, and adhesion.

[0004] In the sintering process of cemented carbide cutting tools, the unsintered cutting tool semi-finished products, usually pressed green blanks, need to be placed in high-temperature resistant containers, i.e. boats, and then sent into high-temperature sintering furnaces. In order to make full use of the furnace space and ensure the circulation of sintering atmosphere, the boats are usually stacked in multiple layers. The function of the boat strips is to be placed between the upper and lower layers of boats as supports and separators.

[0005] However, the above-mentioned related technologies have the following defects. Since the boat strips are independent, smooth strips, they lack effective fixation or connection when placed on the boat. This means that when the stacked boats are moved, such as when using forklifts or trolleys to move them, or when they are loaded into or unloaded from the sintering furnace, they will inevitably be pushed, collided, and vibrated. As a result, the boat strips are very easy to be pushed away from their original position, slip, or even fall off the boat stack. Utility Model Content

[0006] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a mortise and tenon structure for boats and vessels, which can improve the protection effect of boat and vessel strips.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A mortise and tenon joint boat-shaped structure includes two parallel first boat-shaped strips, with two parallel second boat-shaped strips disposed between the two first boat-shaped strips. The first and second boat-shaped strips are perpendicular to each other. The structure also includes a connecting limiting member for connecting the first and second boat-shaped strips so that the two first boat-shaped strips and the two second boat-shaped strips form a quadrilateral frame.

[0009] In some possible embodiments, the connecting limiting member is configured as a connecting part, the connecting part including a first connecting block and a second connecting block that are fixedly connected, a first connecting groove is provided on the side wall of the first boat strip near the second boat strip, the first connecting groove is used for the first connecting block to be inserted, and a second connecting groove is provided on the side wall of the second boat strip near the first boat strip, the second connecting groove is used for the second connecting block to be inserted.

[0010] In some possible embodiments, each of the first boat strips has two first connecting grooves, which are located at both ends of the first boat strip along the same length direction. Each of the second boat strips has a second connecting groove, which is located at both ends of the second boat strip and corresponds to the first connecting grooves one by one.

[0011] In some possible embodiments, the first connecting block is configured as a dovetail block, the first connecting groove is formed as a dovetail block adapted to the first connecting block, the second connecting block is configured as a dovetail block, and the second connecting groove is formed as a dovetail block adapted to the second connecting block.

[0012] In some possible embodiments, the first connecting block is configured as a T-shaped block, the first connecting groove is formed as a T-shaped groove adapted to the first connecting block, the second connecting block is configured as a T-shaped block, and the second connecting groove is formed as a T-shaped groove adapted to the second connecting block.

[0013] In some possible embodiments, the connecting limiting member is configured as a connecting part, which is fixedly disposed on the side wall of the first boat strip near the second boat strip. The second boat strip has a slot for the connecting part to be inserted into. Each of the first boat strips is provided with two connecting parts, which are located at both ends of the first boat strip on the same side along its length.

[0014] In some possible embodiments, the connecting limiting member is configured as a connecting part, which is fixedly disposed at the end of the second boat strip. The first boat strip has a slot for the connecting part to be inserted into. Each second boat strip is provided with two connecting parts, which are disposed at both ends of the second boat strip in the length direction.

[0015] In some possible embodiments, a sliding layer is provided on the sidewall of the connecting limiting member.

[0016] In summary, the technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0017] 1. The first and second boat strips are connected by connecting limiting components to form a quadrilateral frame, which changes the traditional unfixed state of independent boat strips. In scenarios such as forklift handling and furnace loading and unloading, the frame structure can effectively reduce external pushing, collision and vibration, effectively preventing the boat strips from slipping or falling off the boat stack, thereby effectively reducing the risk of boat strips breaking due to falling and improving the protection effect of the boat strips.

[0018] 2. By connecting the first and second boat strips to form a quadrilateral frame through the connecting limiting component, the integrity of the frame is improved, the loss during frame handling is effectively reduced, and the service life of the boat strips is extended. At the same time, the fixing of the boat strips also effectively avoids misalignment between stacking layers, reduces the probability of alloy semi-finished products being damaged by pressure due to the movement of the boat strips, and ensures the integrity of the cemented carbide blank.

[0019] 3. Traditional boat-and-plate stacking requires repeated manual adjustment of the boat-and-plate strips to align the support points between layers. This operation is cumbersome and prone to causing safety accidents due to collisions. This utility model connects the first and second boat-and-plate strips to form a quadrilateral frame through a connecting limiting component, which can quickly achieve positioning and stacking of boat-and-plate stacks. Operators do not need to frequently intervene to make adjustments. On the one hand, it shortens the furnace loading time, and on the other hand, it reduces the working risks for workers in high-temperature working environments, thereby improving the protection of workers to a certain extent.
