Abstract
Description
Technical Field
[0001] This utility model relates to the field of carburizing and quenching technology, and in particular to a carburizing and quenching device. Background Technology
[0002] Carburizing and quenching is a heat treatment process for metallic materials that can improve the surface hardness and wear resistance of workpieces. This process typically includes the following steps: low-temperature tempering, pre-cooling direct quenching, primary heating quenching, high-temperature carburizing and tempering, secondary quenching and cold treatment, and induction heating after carburizing.
[0003] In existing technologies, conventional quenching cooling boxes generally suffer from the problem of difficult-to-clean debris accumulation at the bottom. As impurities such as oxide scale that falls off the workpiece surface and quenching medium residues gradually accumulate at the bottom of the box during the quenching process, traditional structures usually adopt a simple flat-bottom design or a fixed slag discharge port, which requires stopping the machine to empty the medium and manually digging it out during cleaning. This operation is cumbersome and reduces the practicality and production efficiency of the quenching equipment. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a carburizing and quenching device.
[0005] An embodiment of this utility model provides a carburizing and quenching apparatus, comprising:
[0006] Quenching box;
[0007] The chip collection assembly includes a scraper and two chip collection mesh boxes. A raised platform is fixedly installed at the bottom of the quenching box. The two chip collection mesh boxes are abutted against the two sides of the raised platform. A fixed frame is fixedly installed on the chip collection mesh boxes. The scraper is abutted against the upper surface of the raised platform. A U-shaped frame is fixedly installed on the scraper.
[0008] A circulation assembly for circulating the coolant within the quenching chamber.
[0009] Furthermore, the circulation assembly includes a water pump, a first diversion pipe, and a second diversion pipe. The water pump is fixedly installed on the side of the quenching box. The inlet and outlet ends of the water pump are respectively fixedly installed through the first diversion pipe and the second diversion pipe. Multiple suction pipes are installed through the first diversion pipe, and the other ends of the suction pipes are fixedly installed through the bottom side of the quenching box. Multiple outlet pipes are installed through the second diversion pipe, and the other ends of the outlet pipes are fixedly installed through the top side of the quenching box.
[0010] Furthermore, two first guide rods are fixedly installed on the raised platform, and both first guide rods slide through the scraper. Second guide rods are fixedly installed on both inner walls of the quenching box, and both second guide rods slide through the U-shaped frame.
[0011] Furthermore, the top of the fixing frame is provided with a bent portion, which is configured to cooperate with the top of the quenching box.
[0012] Furthermore, an isolation net is fixedly installed at the bottom end of each of the liquid extraction tubes, and the scraper is positioned against the isolation net.
[0013] Furthermore, drain pipes are installed through both ends of the top of the quenching box, and valves are installed on each drain pipe. Support legs are fixedly installed at the four corners of the bottom of the quenching box.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. A chip collection assembly is installed. First, the scraper driven by the U-shaped frame pushes the debris on the platform into the chip collection box. Then, the chip collection box is pulled out as a whole by the fixing frame for cleaning. This structure is simple and reasonable, easy to operate, and can quickly remove debris without stopping the machine, which improves maintenance efficiency and equipment practicality.
[0016] 2. A circulation component is installed. A water pump draws coolant from the bottom of the quenching tank through the extraction pipe and delivers it to the top of the quenching tank through the outlet pipe, forming a forced circulation flow. This structure can effectively promote uniform mixing of the coolant, avoid local temperature differences, and thus improve the stability of the quenching process and the uniformity of workpiece cooling.
[0017] In summary, this utility model features a chip collection component that can quickly remove chips without stopping the machine, improving maintenance efficiency and equipment usability; it also features a circulation component that can avoid local temperature differences, improving the stability of the quenching process and the uniformity of workpiece cooling.

Detailed Implementation
[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0023] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a carburizing and quenching device, comprising:
[0024] The quenching chamber 1 has drain pipes 16 extending through both ends of its top. These drain pipes 16 are used to drain the coolant from the quenching chamber 1. Each drain pipe 16 is equipped with a valve to control its opening and closing. Support legs 17 are fixedly installed at the four corners of the bottom of the quenching chamber 1 to support it.
[0025] The chip collection assembly includes a scraper 6 and two chip collection mesh boxes 3. A lifting platform 2 is fixedly installed at the bottom of the quenching box 1 to raise the chips at the bottom of the quenching box 1. The two chip collection mesh boxes 3 are abutted against the sides of the lifting platform 2 and the inner wall of the quenching box 1, and the upper surface of the chip collection mesh boxes 3 is flush with the upper surface of the lifting platform 2, so that the chips on the lifting platform 2 can be pushed into the chip collection mesh boxes 3. A fixing frame 4 is fixedly installed on the chip collection mesh box 3. The top of the fixing frame 4 is provided with a bent part 5, which is configured to cooperate with the top of the quenching box 1, so that the fixing frame 4 can be raised and the bent part 5 can be hung on the side wall of the quenching box 1 to prevent the fixing frame 4 from shaking and improve stability.
[0026] The scraper 6 is abutted against the upper surface of the lifting platform 2, so that when the scraper 6 moves back and forth, it can push the debris on the upper surface of the lifting platform 2 into the chip collection boxes 3 at both ends. Two first guide rods 8 are fixedly installed on the lifting platform 2, and both first guide rods 8 slide through the scraper 6, guiding the scraper 6. A U-shaped frame 7 is fixedly installed on the scraper 6, which is used to move the scraper 6. Second guide rods 9 are fixedly installed on the inner walls of both sides of the quenching box 1, and both second guide rods 9 slide through the U-shaped frame 7, guiding the U-shaped frame 7.
[0027] A circulation assembly is used to circulate the coolant within the quenching chamber 1. The circulation assembly includes a water pump 10, a first distribution pipe 11, and a second distribution pipe 13. The water pump 10 is fixedly mounted on the side of the quenching chamber 1. The inlet and outlet of the water pump 10 are respectively fixedly mounted through the first distribution pipe 11 and the second distribution pipe 13. Multiple suction pipes 12 are installed through the first distribution pipe 11, with the other end of each suction pipe 12 fixedly mounted through the bottom side of the quenching chamber 1, allowing the water pump 10 to extract coolant from the quenching chamber 1 through the suction pipes 12. An isolation mesh 15 is fixedly installed at the bottom end of each suction pipe 12. The isolation mesh 15 filters debris from the quenching chamber 1, preventing debris from entering the water pump 10. A scraper 6 is positioned against the isolation mesh 15, allowing the scraper 6 to scrape off debris stuck on the isolation mesh 15 as it moves back and forth, preventing blockage. Multiple outlet pipes 14 are installed through the second diversion pipe 13. The other end of each outlet pipe 14 is fixedly installed through the top side of the quenching box 1, so that the water pump 10 can transport the extracted coolant to the top of the quenching box 1 through the outlet pipes 14.
[0028] The detailed working process of this utility model is as follows:
[0029] 1. In use, the water pump 10 can draw out the coolant from the bottom of the quenching box 1 through the suction pipe 12 and the first branch pipe 11, and then transport the drawn coolant to the upper end of the quenching box 1 through the discharge pipe 14 and the second branch pipe 13 to realize the circulation of coolant, avoid temperature difference of coolant in different positions in the quenching box 1, and improve the uniformity and stability of quenching.
[0030] 2. When cleaning debris, first push and pull the scraper 6 back and forth using the U-shaped frame 7. The scraper 6 pushes the debris on the raised platform 2 into the debris collection boxes 3 at both ends. Then, the debris collection box 3 is taken out upwards using the fixing frame 4. The debris in the debris collection box 3 can then be cleaned. The structure is simple, easy to operate, efficient, and practical.
