Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of quenching machine technology, and more specifically, to a high-frequency quenching machine for the tips of circular saw blades. Background Technology

[0002] A circular saw blade is a cutting tool used for low-hardness carbon steel and non-ferrous metal bars and pipes. It is typically made of alloy tool steel and is suitable for processing materials such as angle iron, steel plates, and channel iron. Furthermore, circular saw blades can also be used to saw various cross-sectional shapes of carbon steel, alloy steel, cast iron, and copper and aluminum billets and profiles at room temperature. High-frequency quenching machines are used when quenching the tips of the circular saw blade teeth. A high-frequency quenching machine is a metal surface heat treatment device based on the principle of induction heating, mainly used in the field of machining. It uses high-frequency current (30K-1000KHz). This technology generates a skin effect on the workpiece surface, rapidly heating the material to 800-1000℃ followed by cooling to form a hardened layer that enhances wear resistance while preserving the original properties of the workpiece core. Suitable for steels with a carbon content of 0.40%-0.50%, it is commonly used to strengthen components subjected to alternating loads, such as gears, shafts, and machine tool guideways. The equipment employs IGBT modules and a split-type structure, offering energy savings (20%-30% compared to traditional equipment), rapid heating, and precise temperature control. It supports localized quenching, increasing workpiece surface hardness by 2-3 times. The operation process includes workpiece positioning, high-frequency heating, and rapid cooling (water / oil medium), offering environmentally friendly and pollution-free advantages. The treated workpiece exhibits minimal deformation and uniform microstructure. In existing circular saw blade tooth tip high-frequency quenching machines, after the tooth tip is heated, it is quenched with quenching water. During the quenching process, oxide scale, rust, and other impurities on the surface of the circular saw blade tooth tip will fall into the quenching water. As the number of quenching times increases, the content of these impurities in the quenching water will gradually increase. These impurities may adhere to the surface of the workpiece and affect the quality after quenching. Therefore, the quenching water needs to be replaced frequently. The replaced quenching water is usually treated by direct discharge, without secondary utilization of water resources, resulting in waste of water resources. Utility Model Content

[0022] like Figures 1-4The diagram illustrates a high-frequency quenching machine for circular saw blade tips according to an embodiment of this disclosure. It includes a quenching machine body 1, a processing tank 2, a first water pump 3, a second water pump 4, a slide rail 5, a sliding seat 6, a stirring mechanism, a rack 7, a drive assembly, and a filtering mechanism. Compared to existing technologies where high-frequency quenching machines for circular saw blade tips typically treat quenching water by direct discharge without secondary utilization, resulting in water waste, this embodiment addresses this issue by utilizing the cooperation between the slide rail 5, sliding seat 6, stirring mechanism, rack 7, and drive assembly to achieve efficient water treatment of the incoming water. The reciprocating agitation of the quenching water inside the treatment tank 2 removes impurities, facilitating subsequent filtration. The filtration mechanism achieves multi-stage filtration of impurities in the quenching water, reducing its quantity and enabling reuse. The cooperation between the treatment tank 2, the first water pump 3, and the second water pump 4 ensures the cyclical transport of quenching water within the quenching pool of the quenching machine body 1, enabling the reuse of treated quenching water and reducing water waste.

[0023] like Figure 1 As shown, the processing box 2 is located on one of the two sides of the quenching machine body 1. The output end of the first water pump 3 is connected to the upper side of the processing box 2 through a water inlet pipe, and the input end of the first water pump 3 is connected to the drain outlet of the quenching tank inside the quenching machine body 1 through a suction pipe. The input end of the second water pump 4 is connected to the lower side of the processing box 2 through a drain pipe, and the output end of the second water pump 4 is connected to the water inlet of the quenching tank inside the quenching machine body 1 through a delivery pipe. Figure 2 As shown, two slide rails 5 are installed on the upper side of the processing box 2. A sliding seat 6 is slidably connected to each slide rail 5. The two slide rails 5 are symmetrically arranged and are I-shaped. Limiting baffles are installed on both sides of each slide rail 5. The slide rails 5 and the limiting baffles can limit the sliding of the sliding seat 6, thus ensuring the stability of the sliding seat 6 when it slides on the slide rails 5. An agitation mechanism is located on the lower side of the sliding seat 6. The agitation mechanism includes an agitation shaft 101 and an agitation frame 102. The agitation shaft 101 is rotatably mounted on the lower side of the sliding seat 6. A driving component for driving the agitation shaft 101 to rotate is provided on the sliding seat 6. The driving component is a forward and reverse reversing motor. Multiple agitation frames 102 are installed on the outer side of the agitation shaft 101. A movable opening is provided on the upper side of the processing box 2. The width of the movable opening is 1.15 times the outer diameter of the agitation shaft 101. When the agitation mechanism moves inside the processing box 2, the agitation shaft 101 moves inside the movable opening. Figure 3As shown, multiple racks 7 are installed on the upper side of the processing box 2. The drive assembly is set on the sliding seat 6. The drive assembly includes a rotating shaft 201 and a transmission gear 202. The rotating shaft 201 is rotatably installed inside the sliding seat 6. The sliding seat 6 is provided with a drive component for driving the rotating shaft 201 to rotate. The drive component is a reciprocating motor. The transmission gear 202 is sleeved on the rotating shaft 201. The transmission gear 202 meshes with the racks 7. like Figure 2 As shown, the filtration mechanism is located inside the processing chamber 2. The filtration mechanism includes a mounting baffle 301, filter frames 302, a first filter layer 303, and a second filter layer 304. The mounting baffle 301 is inserted into the processing chamber 2. Two filter frames 302 are installed on one side of the mounting baffle 301. The first filter layer 303 is located at the bottom of the inner wall of the upper filter frame 302, and the second filter layer 304 is located at the bottom of the inner wall of the lower filter frame 302. Both the first filter layer 303 and the second filter layer 304 are composed of multiple filter screens. The pore size of the multiple filter screens decreases sequentially from top to bottom. The multiple filter screens with different pore sizes filter impurities in the quenching water step by step, enhancing the filtration effect of the first filter layer 303 and the second filter layer 304 on the quenching water. Figure 4 As shown, a spring-loaded mounting assembly is provided on one of the two sides of the treatment box 2. The spring-loaded mounting assembly includes a cylinder 401, a connecting rod 402, a pressing plate 403, and a return spring 404. The cylinder 401 is mounted on one of the two sides of the treatment box 2 via a mounting block. The connecting rod 402 is inserted into the cylinder 401, and one end of the connecting rod 402 is connected to the outside of the mounting baffle 301. The pressing plate 403 is mounted on the other end of the connecting rod 402. The return spring 404 is sleeved on the connecting rod 402, and both ends of the return spring 404 are connected to the cylinder 401 and the pressing plate 403, respectively. The spring-loaded mounting mechanism enables the filter mechanism to be quickly pulled out from the inside of the treatment box 2 and automatically returned to its original position.

[0024] Working principle: When the quenching water needs to be treated, the forward and reverse motors are started. These motors drive the agitator shaft 101 to rotate, which in turn drives the agitator frame 102 to rotate. Then, the reciprocating motor is started, driving the rotating shaft 201 to rotate. This rotating shaft 201 drives the transmission gear 202 to rotate, which crawls along the rack 7. The transmission gear 202, through the rotating shaft 201, drives the sliding seat 6 to slide back and forth along the slide rail 5. The sliding seat 6, through the agitator shaft 101, drives the agitator frame 102 to move back and forth inside the treatment tank 2. Finally, the first water pump 3 is started. The first water pump 3 transports the quenching water from the quenching pool inside the quenching machine body 1 to the treatment tank 2 through the suction pipe and the inlet pipe. Inside, the stirring rack 102 agitates the quenching water entering the processing tank 2. After agitation, the quenching water flows through the first filter layer 303, where multiple filter screens pre-filter impurities. After pre-filtration, the quenching water flows through the second filter layer 304, where multiple filter screens pre-filter impurities. After multi-stage filtration, the quenching water flows to the bottom of the processing tank 2. Then, the second water pump 4 is started, and the second water pump 4 transports the treated quenching water through the drain pipe and conveying pipe to the quenching pool inside the quenching machine body 1, realizing the recycling of the treated quenching water.
