Detailed Implementation

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides a multi-compartment flange forging strengthening and toughening heat treatment equipment, including: heat treatment integrated equipment 1 and operating components 2; The heat treatment integrated equipment 1 is provided with a heating and insulation chamber 101 and a quenching and cooling chamber 102. The top of the heating and insulation chamber 101 is provided with an automatic opening and closing cover 1011. Connecting legs 103 are fixedly connected to the four sides of the heat treatment integrated equipment 1. At the same time, the top of the heat treatment integrated equipment 1 is provided with a running component 2, which includes the following components: Fixed support frame 201: Fixedly connected to the top of the connecting leg 103, and a lead screw 2011 is rotatably installed inside the fixed support frame 201. One end of the lead screw 2011 is fixedly connected to the drive end of the linkage motor 2012. Movable belt block 202: Located at the top of the fixed support frame 201, a connecting protrusion 2021 is fixedly connected to the middle of the movable belt block 202, and a threaded hole 2022 is opened on the connecting protrusion 2021. At the same time, stabilizing pulleys 2023 are fixedly connected to both sides of the bottom of the movable belt block 202. Fixed support 203: Fixedly connected to the top of the movable belt block 202. A rotating bracket 2031 is fixedly connected to the top of the fixed support 203. A take-up and release roller 2032 is provided between the rotating brackets 2031. A driven pulley 2033 is fixedly connected to the outer side of the take-up and release roller 2032. Drive motor 204: Fixedly installed on the top of the moving belt block 202. Drive pulley 2041 is fixedly connected to the drive end of drive motor 204. Drive pulley 2041 is rotatably connected to driven pulley 2033 through transmission belt 2042. Connecting slide frame 205 is fixedly connected to one side of moving belt block 202. Guide pulleys 2051 are provided on both sides of the top of connecting slide frame 205. The wire rope 2052 on take-up and release roller 2032 is fixedly connected to the hanger 2053 at the bottom through guide pulleys 2051. Hook 2054 is provided at the bottom of hanger 2053. Connecting plate 2055 is provided between hooks 2054.

[0022] By hanging the flange forging onto the hook 2054, the linkage motor 2012 is started to drive the lead screw 2011 to rotate. The lead screw 2011 engages with the threaded hole 2022 on the moving belt block 202, causing it to move the moving belt block 202. When it moves to the top of the heating and insulation chamber 101, the automatic opening and closing cover 1011 is opened, and then the drive motor 204 is started to drive the take-up and release roller 2032 to rotate, thereby lowering the hanger 2053 into the heating and insulation chamber 101 via the wire rope 2052. At the same time, the connecting plate 2055 can be sealed to prevent heat loss. Then, the flange forging is heated in the heating and insulation chamber 101. After heating, the heating and insulation chamber 101 is adjusted to a constant temperature. The flange forging is then heat-insulated to obtain martensite. A drive motor 204 drives a take-up roller 2032 to wind it up, and a wire rope 2052 lifts the hanger 2053. A lead screw 2011 drives a moving belt block 202 to move it into the top of the quenching and cooling chamber 102. The forging is then placed in the coolant inside the chamber for quenching and cooling to improve its strength. A connecting plate 2055 seals the top of the chamber to prevent steam from splashing out. The flange forging is then lifted and moved back into the heating and insulation chamber 101 for tempering, reducing the internal stress and improving its toughness. Finally, the tempered forging is placed back into the quenching and cooling chamber 102 for cooling, completing the overall strengthening and toughening process.

[0023] Example 2: Based on Example 1, wherein, as Figures 4 to 6As shown, a filter assembly 3 is provided on one side of the quenching cooling chamber 102. The filter assembly 3 includes a discharge pipe 301 and a filter box 302. The discharge pipe 301 is fixedly connected to the bottom of the quenching cooling chamber 102. A check valve 3011 and a flow stop valve 3012 are installed at the bottom of the discharge pipe 301. The filter box 302 is fixedly connected to one side of the quenching cooling chamber 102. A connecting side frame 3021 is fixedly connected to both sides inside the filter box 302. A fixed side plate 3022 is fixedly connected to the front end of the connecting side frame 3021. A connecting slide rod 3023 is fixedly connected between the fixed side plate 3022 and one end inside the filter box 302. A limit protrusion 3024 is fixedly connected to the outside of the connecting slide rod 3023. A spring 3025 is provided on the outside of the connecting slide rod 3023.

[0024] A compression slip ring 303 is slidably mounted on the outer side of the connecting slide rod 3023, and an extension protrusion 3031 is fixedly connected to one side of the compression slip ring 303.

[0025] A fixing plate 304 is fixedly connected to the rear side of the filter box 302. The fixing plate 304 has a mating groove 3041 inside, and a limit pin 3042 is inserted into the mating groove 3041.

[0026] A filter plate 305 is provided between the connecting side frames 3021. A docking block 3051 is fixedly connected to one end of the filter plate 305. The docking block 3051 is inserted into the docking groove 3041, and a limit insertion hole 3052 is provided on the docking block 3051. At the same time, the limit pin 3042 is inserted into the limit insertion hole 3052.

[0027] The top of the filter box 302 is equipped with a pump body 306. One end of the pump body 306 is connected to the quenching and cooling chamber 102 through the extraction pipe 3061, and the other end of the pump body 306 is fixedly connected to the discharge pipe 301 through the delivery pipe 3062.

[0028] When the heated forging enters the coolant, impurities are generated in the coolant. At this time, the coolant is drawn out by activating the pump body 306 and then transported to the filter box 302. It is filtered by the filter plate 305, and the filtered coolant flows back to the discharge pipe 301 through the delivery pipe 3062 and finally flows back to the quenching cooling chamber 102. When cleaning the filter plate 305, the limiting pin 3042 is pulled out to release the limiting of the filter plate 305. Under the elastic action of the spring 3025, the compression slip ring 303 is pushed to move. The compression slip ring 303 drives the extension protrusion 3031 to push the filter plate 305 out for easy disassembly. After cleaning, the filter plate 305 is reinserted into the connecting side frame 3021. When it is pushed, the extension protrusion 3031 drives the compression slip ring 303 to move and compress the spring 3025. When one end of the filter plate 305 is inserted into the docking groove 3041, the limiting pin 3042 is inserted back to complete the limiting.

[0029] The specific usage and function of this embodiment are as follows: In this invention, the flange forging is hung on the hook 2054, and then the linkage motor 2012 is started to drive the lead screw 2011 to rotate. The lead screw 2011 rotates and engages with the threaded hole 2022 on the moving belt block 202, causing it to move the moving belt block 202. When it moves to the top of the heating and insulation chamber 101, the automatic opening and closing cover 1011 is opened by controlling it. Then, the drive motor 204 is started to drive the take-up and release roller 2032 to rotate, thereby passing through the wire rope 2052. Lower the hanger 2053 into the heating and insulation chamber 101. Simultaneously, the connecting plate 2055 can be sealed to prevent heat loss. Then, heat the flange forging within the heating and insulation chamber 101. After heating, adjust the chamber 101 to a constant temperature and insulate the heated flange forging to achieve martensite formation. Then, drive the take-up and untake-down rollers 2032 via the drive motor 204 to wind it up, and secure the hanger 2053 with the wire rope 2052. The forging is lifted and then moved by the lead screw 2011 to the top of the quenching and cooling chamber 102. It is then placed in the coolant inside the quenching and cooling chamber 102 for cooling and quenching, which improves the strength of the forging. At the same time, the top of the quenching and cooling chamber 102 is sealed by the connecting plate 2055 to prevent steam from splashing out. Then, the flange forging is lifted and moved back into the heating and insulation chamber 101 for tempering, which reduces the internal stress of the forging after quenching and improves its toughness. Then, the tempered forging is placed in the quenching and cooling chamber 102 for cooling, which completes the overall toughening process. This integrates the toughening process into an integrated device, which speeds up the transfer speed of the forging and improves the processing efficiency of the forging. The connecting plate 2055 can seal the top opening of the chamber, which reduces heat loss during heating and insulation and prevents steam from splashing out during quenching. This reduces energy consumption, ensures a safe working environment, maintains a stable temperature inside the chamber, and improves the quality of heat treatment.
