[0022] The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0023] Please refer to Figure 1-6 , an embodiment of the present invention provides a technical solution: an interval rod frame heat treatment tooling, including a base 1, on which a plurality of rotating seats 3 are rotatably connected, and a screw 4 is fixedly installed on each rotating seat 3. Connecting nuts are fixedly connected to a plurality of rotating seats 3, and a plurality of screws 4 are detachably connected to the rotating seats 3 through the connecting nuts, so that the screws 4 can be conveniently disassembled, assembled and replaced. A fixing mechanism 2 is provided at the top of a plurality of screws 4, and a tightness adjustment mechanism 5 is provided on the fixing mechanism 2. By rotating and staggering the placement of a plurality of frames with the hanging plate holes of the frame anti-vibration damper as the reference points, the fixing mechanism 2 fixes the frames to form an iron building, and the tightness adjustment mechanism 5 is used to adjust the tightness, so as to allow a certain expansion and contraction space when the frames thermally expand.
[0024] The fixing mechanism 2 includes a top cover 201 and a plurality of movable blocks 202. A plurality of connecting grooves 203 are formed in the top cover 201. The plurality of movable blocks 202 are sleeved on the screw rod 4, and the movable blocks 202 are matched with the connecting grooves 203, so that the movable blocks 202 can move on the screw rod 4 and can be inserted into the connecting grooves 203. A guiding chute 204 is provided on one side of each connecting groove 203. A guiding slider 206 is slidably connected inside the guiding chute 204. A shifting block 205 is fixedly connected to the outside of the guiding slider 206. A return spring 207 is provided at one end of the guiding slider 206. The shifting block 205 is slidably connected to the top cover 201 through the guiding slider 206 and the guiding chute 204. The return spring 207 is arranged between the guiding slider 206 and the inner wall of the guiding chute 204, so that the return spring 207 can reset the guiding slider 206. A latch 208 is fixedly connected to the inner side of the guiding slider 206, and the latch 208 can be inserted into the movable block 202, so that the top cover 201 can move synchronously with the movable block 202. A slot 209 is formed on the side of the movable block 202 away from the latch 208. A fixing knob 210 is provided on one side of the slot 209. The end of the fixing knob 210 is drivingly connected to a fixing screw rod 212 through a bevel gear pair 211. Both the fixing knob 210 and the fixing screw rod 212 are rotatably connected to the inner wall of the top cover 201. The end of the fixing knob 210 penetrates through the top cover 201 and communicates with the outside, so that it is convenient to rotate the fixing knob 210. A fixing thread sleeve 213 is threadedly connected to the fixing screw rod 212. A threaded block 214 is fixedly connected to the end of the fixing thread sleeve 213. A guiding rod 215 is slidably connected to the top of the fixing thread sleeve 213. The guiding rod 215 is fixedly connected to the inner wall of the top cover 201. The threaded block 214 is matched with the screw rod 4, so that the threaded block 214 can fix the screw rod 4. Multiple frames can be rotatably and staggeredly placed on the base 1 with the frame anti-vibration hanger plate holes as the reference points, and then the multiple screw rods 4 are rotated to make them stand up. Then, the shifting block 205 is pushed. The movement of the shifting block 205 drives the guiding slider 206. The movement of the guiding slider 206 drives the latch 208 to move and compresses the return spring 207. The movable block 202 is pushed into the connecting groove 203. The shifting block 205 is released, and the return spring 207 resets the guiding slider 206, so that the latch 208 is inserted into the movable block 202, and the top cover 201 and the movable block 202 can be connected to move synchronously. Then, the fixing knob 210 is rotated. The rotation of the fixing knob 210 drives the fixing screw rod 212 to rotate. The rotation of the fixing screw rod 212 drives the fixing thread sleeve 213 to move. The movement of the fixing thread sleeve 213 drives the threaded block 214 to move, so that the threaded block 214 enters the movable block 202 and abuts against the screw rod 4, and the top cover 201 is fixed by using the thread, forming an iron tower with multiple frames.
[0025] The tightness adjustment mechanism 5 includes a pressure plate 501, on which an adjusting nut 502 and a plurality of telescopic rods 505 are fixedly connected. The top ends of the telescopic rods 505 are fixedly connected to the top cover 201. The telescopic rods 505 can guide the movement of the pressure plate 501. An adjusting screw 503 is threadedly connected inside the adjusting nut 502. The adjusting screw 503 is rotatably connected to the top cover 201. The top end of the adjusting screw 503 is fixedly connected with an adjusting head 504. By rotating the adjusting head 504, the rotation of the adjusting head 504 drives the rotation of the adjusting screw 503. The rotation of the adjusting screw 503 drives the movement of the adjusting nut 502. The movement of the adjusting nut 502 drives the movement of the pressure plate 501 to adjust the tightness of the frame, so that the frame has a certain expansion space when it thermally expands.
[0026] A use process of a spacer frame heat treatment tooling includes the following steps: Step 1. Installation: Rotate and stagger the placement of multiple frames with the hanging plate holes of the frame anti-vibration damper as the reference points. Use the tooling to fix multiple frames to form an iron tower, which is convenient for quenching and annealing operations on multiple frames at the same time, and adjust the tightness so that the frame has a certain expansion space when it thermally expands.
[0027] Step 2. Step-by-step water immersion: After heating, immerse the iron tower in water for cooling step by step within 60S. In step 2, immerse the iron tower in water step by step according to the standard of putting down 1 / 8 of the iron tower each time, and pause between each step of putting down. Continue to put down after the bubbles generated by boiling are less.
[0028] Step 3. Annealing: Lift the iron tower out of the quenching furnace and then place it on a customized tray, and directly send it into the annealing furnace for annealing. In step 3, the size of the customized tray is set to 15000*750 cm, and a forklift is used to carry the customized tray in step 3.
[0029] In summary, omitting the shaping step has the following advantages: Saving labor: Originally planned 2 people / shift, one person to disassemble the tooling and one person to shape, divided into two shifts, 4 people were needed, and the daily shaping quantity was about 1500. Now, no manual shaping is required, and the number of heat-treated frames is nearly 130,000, saving 350 workers. If it is 200 yuan per person, about 70,000 yuan is saved.
[0030] Saving the cost of shaping molds: There are many types of frames, such as 2 types of eight-split, 2 types of six-split, and 3 types of four-split. If the original process is carried out, seven new shaping molds need to be opened, and the cost is as high as about 250,000 yuan. Now, omitting the shaping step can greatly reduce the production cost.
[0031] Reducing the product turnover time: The frame does not need to be shaped, which reduces a process between quenching and annealing, and greatly improves the quantity of heat treatment of the frame.
