Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a brazing conveying device for cutting teeth. Background Technology

[0002] Cutting teeth are key components of mining and tunneling machinery, primarily used in coal mining and tunneling operations. They are categorized by application into coal mining machine cutting teeth and tunneling machine cutting teeth, with the latter requiring higher hardness and impact resistance. Cutting teeth work in conjunction with cutting tooth sleeves and cutting tooth seats; these three components utilize alloy steel and carbide heads to enhance wear resistance, and structural optimization improves stress distribution.

[0003] Cutting teeth are typically welded from a tooth body to a carbide tip, and can be divided into two types: pick-shaped (conical) and blade-shaped (flat). In existing cutting teeth, the tooth tip and tooth disc, and the tooth disc and tooth shank are brazed simultaneously during the brazing process. This method involves brazing the tooth tip and tooth disc, and the tooth disc and tooth shank together, followed by quenching. In this case, the overall hardness and toughness after brazing are not ideal, and the overall process is also relatively complex, requiring two steps: first brazing, then quenching.

[0004] Although the brazing process is simplified after adopting the tempering process, only the tooth head and tooth shank need to be brazed. Since the tooth shank and tooth shank have been pre-tempered, when the tooth head and tooth shank are brazed again, the pre-tempered brazed part (i.e. the connection between the tooth shank and tooth shank) is prone to melting due to temperature. Even if it is cooled in the subsequent quenching process, the melting has already occurred, which may result in cracks that are not visible to the naked eye, affecting subsequent use and making it impossible to guarantee the quality.

[0008] A conveying mechanism located within the quenching tank;

[0009] A rotary fixture, wherein there are several rotary fixtures, and the rotary fixtures are rotatably mounted on the conveying mechanism. The conveying mechanism drives the rotary fixtures to move to the loading and unloading station, the welding station and the quenching station. The side wall of the rotary fixture is provided with several cooling through holes, and the rotary fixture is provided with a first transmission part.

[0010] A rotary drive mechanism is located at the quenching station and is connected to the first transmission part of the rotary fixture located at the quenching station, thereby driving the rotary fixture to rotate.

[0011] As a preferred embodiment of the above technical solution, the quenching station is located below the welding station.

[0012] As a preferred embodiment of the above technical solution, the conveying mechanism includes a conveying motor, a conveying chain, and several conveying plates. The conveying motor is connected to the conveying chain for transmission. The several conveying plates are evenly arranged on the conveying chain. The rotating clamp is rotatably mounted on the conveying plate.

[0019] This utility model provides a brazing conveying device for cutting teeth, comprising: a quenching tank, a conveying mechanism, a rotating fixture, and a rotating drive mechanism. The quenching tank is used to hold quenching liquid. The conveying mechanism is located inside the quenching tank and is used to transport the rotating fixture cyclically between the loading / unloading station, the welding station, and the quenching station. The rotating fixture has a receiving space for accommodating and fixing the cutting teeth to be processed. During welding, quenching liquid is first injected into the quenching tank, and the liquid level must be sufficient to cover the shank of the cutting tooth located at the quenching station. The cutting tooth to be processed is fixed on the rotating fixture at the loading / unloading station. Subsequently, the conveying mechanism drives the rotating fixture to move to the welding station, and the rotating drive mechanism is activated, driving the rotating fixture to rotate. Simultaneously, an external welding device welds the cutting teeth. During the welding process, the rotating fixture continuously rotates to ensure uniform welding. Quenching liquid flows into the rotating fixture from the cooling through-hole to cool the tooth shank of the cutting teeth, preventing overheating that could cause the brazed part (i.e., the connection between the tooth disc and the tooth shank) to melt, thus ensuring the product quality of the cutting teeth. After welding is completed, the conveying mechanism continues to move the rotating fixture to the quenching station. At this time, the cutting teeth located at the quenching station are immersed in the quenching liquid to achieve rapid cooling, thereby improving the hardness and wear resistance of the cutting teeth. Finally, the conveying mechanism sends the rotating fixture back to the loading and unloading station, where the operator removes the finished cutting teeth and fixes the new cutting teeth to be processed on the rotating fixture, thus realizing the cyclic operation. By setting up a linkage structure between the conveying mechanism and the rotary drive mechanism, the rotary fixture can achieve stable rotation at the welding station, ensuring the uniformity and reliability of the welding process. At the same time, the reasonable control of the liquid level in the quenching tank allows for the cooling of the cutting tooth shank during welding and the overall immersion of the cutting tooth in the quenching station, thereby further ensuring the product quality of the cutting tooth.

[0033] This utility model provides a brazing conveying device for cutting teeth, including: a quenching tank 1, a conveying mechanism 2, a rotating clamp 3, and a rotating drive mechanism 4. The quenching tank 1 is used to hold quenching liquid. The conveying mechanism 2 is located inside the quenching tank 1 and is used to transport the rotating clamp 3 to move cyclically between the loading / unloading station, the welding station, and the quenching station. The rotating clamp 3 has a receiving space for accommodating and fixing the cutting teeth to be processed. During welding, quenching liquid is first injected into the quenching tank 1, and the liquid level must be sufficient to cover the shank of the cutting tooth located at the quenching station. The cutting tooth to be processed is fixed on the rotating clamp 3 at the loading / unloading station. Then, the conveying mechanism 2 drives the rotating clamp 3 to move to the welding station. The rotating drive mechanism 4 is activated, driving the rotating clamp 3 to move cyclically between the loading / unloading station and the welding station. The rotating fixture 3 rotates, and simultaneously, the external welding device welds the cutting teeth. During the welding process, the rotating fixture 3 continues to rotate to ensure uniform welding. Quenching liquid flows into the rotating fixture 3 from the cooling through hole 301 to cool the tooth shank of the cutting teeth, preventing overheating that could cause the brazed part (i.e., the connection between the tooth disc and the tooth shank) to melt, thereby ensuring the product quality of the cutting teeth. After welding is completed, the conveying mechanism 2 continues to move the rotating fixture 3 to the quenching station. At this time, the cutting teeth located at the quenching station are immersed in the quenching liquid to achieve rapid cooling, thereby improving the hardness and wear resistance of the cutting teeth. Finally, the conveying mechanism 2 sends the rotating fixture 3 back to the loading and unloading station. The operator removes the finished cutting teeth and fixes the new cutting teeth to be processed on the rotating fixture 3, thus realizing the cyclic operation. By setting up a linkage structure between the conveying mechanism 2 and the rotary drive mechanism 4, the rotary fixture 3 can achieve stable rotation at the welding station, ensuring the uniformity and reliability of the welding process. At the same time, the reasonable control of the liquid level in the quenching tank 1 allows for the cooling of the cutting tooth shank during welding and the overall immersion of the cutting tooth in the quenching station, thereby further ensuring the product quality of the cutting tooth.

[0034] In a further embodiment of this invention, the quenching station is located below the welding station.

[0035] In this embodiment, the quenching station is located below the welding station. This design allows the conveying mechanism 2 to move the rotating fixture 3 from the welding station to the quenching station without going through a complex turning structure, thus achieving a smooth transition. At the same time, it ensures that the quenching liquid can fully cover the entire cutting tooth located at the quenching station, thereby effectively improving the cooling efficiency and quenching effect.

[0037] In this embodiment, the conveying mechanism 2 includes a conveying motor 201, a conveying chain 202, and several conveying plates 203. The conveying motor 201 drives the conveying chain 202 to operate, causing each conveying plate 203 to move along a predetermined trajectory, thereby realizing continuous conveying of the rotary fixture 3 between different workstations. The rotary fixture 3 is rotatably mounted on the conveying plate 203.

By adjusting the position of the bolts in the fixed slide groove 208, the position of the tensioning shaft 205 can be adjusted, thereby achieving precise adjustment of the tension of the conveying chain 202. This ensures that the conveying chain 202 maintains a stable tension during long-term operation, effectively preventing the conveying chain 202 from becoming loose or skipping teeth during operation, and improving the reliability and lifespan of the equipment.

[0042] In a further embodiment of this invention, the conveyor plate 203 is provided with a mounting hole 209, and the rotary clamp 3 is provided with a mounting shaft 303.

A bushing is provided in the mounting hole 209, and the bushing is clearance-fitted with the mounting shaft 303, allowing the rotating clamp 3 to rotate flexibly on the conveyor plate 203 while maintaining stability and accuracy during rotation. This avoids shaking or displacement caused by excessive clearance, thereby ensuring the continuity and high quality of the welding and quenching processes.
