[0002] The flange valve body is a common valve component used to control the flow of fluid in the pipeline. It is connected to the pipeline through a flange. This connection method is relatively firm, can withstand greater pressure and torque, and is easy to install and disassemble. It usually has a sturdy structure and can withstand pressure and temperature changes of the fluid in the pipeline. Different types of flange valve bodies are suitable for different working conditions and media. The flange valve body is a critical component in the pipeline system, and its performance and quality directly affect the operating efficiency and safety of the entire system.

[0039] Example 3, using Figure 7-Figure 9 The forging equipment of a flange valve body forging of the present invention is described as follows:

[0040] like Figure 7-Figure 9 It is shown that a forging device for a flange valve body forging of the present invention is based on the first embodiment;

[0041] The upper mold component 6 includes an upper mold base 61, the top of the upper mold base 61 is fixedly connected to the bottom of the movable plate 5, blocks 62 are fixedly connected to both sides of the upper mold base 61, a circular arc groove 63 is provided at the bottom of the upper mold base 61, sliding grooves 612 are provided on both sides of the bottom of the upper mold base 61, sliding rods 64 are fixedly connected to both sides of the upper mold base 61, a connecting sleeve 65 is slidably connected to the side of the sliding rod 64, one end of the connecting sleeve 65 is fixedly connected to a slider 66, the inner side of the slider 66 is slidably connected to the side of the sliding rod 64, a fourth spring 69 is sleeved on the sliding rod 64, one end of the fourth spring 69 is fixedly connected to the inner wall of the sliding groove 612, and the other end of the fourth spring 69 is fixedly connected to the side of the connecting sleeve 65.

The other end of the connecting rod 611 is rotatably connected to a contact block 613. A connecting frame 67 is fixedly connected to the side of the slider 66, and a scraper mechanism 610 is fixedly connected to the side of the connecting frame 67. When the upper die seat 61 moves downward, the contact block 613 is squeezed and contacted with the top of the placement seat 71, so that the contact block 613 drives the connecting sleeve 65 to move on the sliding rod 64 through the connecting rod 611, and at the same time, the connecting sleeve 65 drives the scraper mechanism 610 to move outward through the slider 66 and the connecting frame 67, so as to avoid the scraper mechanism 610 interfering with the forging work during the forging work.

[0042] The scraper mechanism 610 includes a round rod 6101, one end of which is fixedly connected to the connecting frame 67, and the other end of the round rod 6101 is fixedly connected to an arc plate 6102, and both sides of the arc plate 6102 are fixedly connected to bent plates 6103. When the upper die seat 61 moves upward after the forging work is completed, when the contact block 613 and the placement seat 71 release the extrusion limit, the connecting sleeve 65 drives the slider 66 to move in the sliding groove 612 through the stretching and resetting action of the fourth spring 69, so that the connecting frame 67 drives the arc plate 6102 through the round rod 6101 to clean and scratch the inner wall of the arc groove 63. By arranging bent plates 6103 on both sides of the arc plate 6102, the oxide scale attached to the arc groove 63 can be scraped off.

[0043] The specific workflow is as follows:

[0044] During operation, the heated forging is placed in the connecting component 7, and the electric hydraulic cylinder 4 is turned on. The output end of the electric hydraulic cylinder 4 drives the upper die component 6 to move downward through the moving plate 5, so as to forge the forging in the connecting component 7. At the same time, the protective component 8 can protect the surroundings during the forging operation.

[0045] When the heated forging is placed in the placement groove 72, the upper die seat 61 is driven downward by the output end of the electric hydraulic cylinder 4 to forge, and the die rod 75 is driven to move toward the forging through the output end of the motor 74, so that the forging is punched. At the same time, when the upper die seat 61 and the placement seat 71 are squeezed, the cooling mechanism 76 can be squeezed, so as to cool the placement seat 71 after forging;

At the same time, when the forging work is completed, the upper die seat 61 separates from the extrusion plate 764 and moves upward, and the water in the water tank 1 761 flows into the water tank 2 762 through the through hole 767, and the extrusion rod 763 is driven upward by the stretching reset of the first spring 766 through the extrusion plate 764, so that the extrusion plate 764 is reset;

[0047] When the upper die seat 61 moves downward, the upper die seat 61 drives the block 62 and the limit plate 84 to be squeezed, and the limit plate 84 drives the rack 2 88 to move downward in the protection groove 81, and is meshed with the rack 2 88 through the gear 87, so that the gear 87 rotates in the protection groove 81. Since the rack 1 86 and the gear 87 are meshed, the protection plate 89 is driven upward by the rack 1 86. Therefore, during the forging work, the protection plate 89 can protect the surrounding staff, thereby preventing impurities generated during the flange valve forging work from splashing to the surrounding staff. At the same time, when the block 62 releases the squeeze on the limit plate 84, the limit plate 84 is reset by the stretching of the second spring 85, so that the rack 2 88 moves upward in the protection groove 81. At the same time, driven by the gear 87, the rack 1 86 drives the protection plate 89 to move downward, and then the cleaning mechanism 811 cleans the protection plate 89.

[0048] When the protection plate 89 moves downward in the protection groove 81, the scraper 8112 contacts the side of the protection plate 89, so that the side of the protection plate 89 is cleaned when the protection plate 89 moves, so as to prevent the side of the protection plate 89 from being attached to the splashed impurities and remaining on the protection plate 89 during the forging work. At the same time, when the protection plate 89 continues to move downward, it can move against the roller 8114, so as to wipe the area cleaned by the scraper 8112;

[0049] When the upper die seat 61 moves downward, the contact block 613 is pressed and contacted with the top of the placement seat 71, so that the contact block 613 drives the connecting sleeve 65 to move on the sliding rod 64 through the connecting rod 611, and the connecting sleeve 65 drives the scraper mechanism 610 to move outward through the slider 66 and the connecting frame 67, so as to avoid the scraper mechanism 610 interfering with the forging work during the forging work;

[0050] When the upper die seat 61 moves upward after the forging work is completed, and the contact block 613 and the placement seat 71 release the extrusion limit, the connecting sleeve 65 drives the slider 66 to move in the sliding groove 612 through the stretching and resetting action of the fourth spring 69, so that the connecting frame 67 drives the arc plate 6102 to clean and scratch the inner wall of the arc groove 63 through the round rod 6101. By arranging bent plates 6103 on both sides of the arc plate 6102, the oxide scale attached to the arc groove 63 can be scraped off.
