Technical Field

[0002] Butterfly valves, also known as flap valves, are a type of simple regulating valve that can be used for on / off control and flow regulation of low-pressure pipeline media. The valve core is the core pressure-bearing component for valve opening, closing and sealing. Forging is the mainstream process for forming high-end blanks. The heated metal blank is plastically formed under pressure in a special mold, which can refine the metal grains and eliminate casting porosity defects.
[0003] For example, Chinese Patent No. CN223476231U discloses a gear disc forging blanking device, including a hot forging press. The right side of the worktable of the hot forging press is provided with a blanking robot that can be lifted and moved left and right. Below the blanking robot is a blanking conveying device, and the discharge end of the blanking conveying device is provided with a receiving device.
[0004] The above-mentioned device realizes automated blanking of die forging through blanking robot. However, when blanking the die forging of butterfly valve core, the valve plate of butterfly valve core is relatively thin and the temperature of butterfly valve core is still high after die forging, making it easy to deform. Using robot to clamp and blank the workpiece can easily damage the surface of the workpiece, resulting in surface damage such as indentation and scratches, which leads to damage to the appearance of the workpiece.

[0016] Compared with existing technologies, the advantages of this invention are: 1. This invention achieves contactless automatic demolding of valve core forgings through the setting of the feeding component and the lower mold component. At the same time, while the transmission plate moves, it can drive the piston rod to squeeze the gas inside the connecting pipe. Secondary pressurization can be achieved without additional drive, which can make the gas discharged from the micro-holes more quickly lift the valve core forging. Compared with ejector rod demolding, it can avoid the valve core forging from local deformation such as indentations and dimples caused by ejector rod extrusion, which greatly improves the appearance quality of the forging. It is suitable for the production needs of thin and easily deformable die forgings such as butterfly valve cores. At the same time, the high-pressure airflow at the moment of demolding can back-flushing the micro-holes of the cavity, reducing the blockage of the channels caused by residual mold release agent and accumulation of trace impurities, ensuring long-term exhaust and smooth airflow in the micro-holes, and improving the stability and service life of continuous mold production. 2. This invention, through the setting of mounting blocks, adjustment components, feeding components, and flipping sliding components, utilizes the flipping of the support plate and gravity sliding combined with belt conveyor transportation to adopt a clamp-free feeding method, avoiding indentations and scratches caused by clamping, further ensuring the appearance quality of the forgings. At the same time, by utilizing the gap design of multiple sets of rotating rollers on the support plate, the die forging residues adhering to the surface of the valve core forging can fall directly into the collection tank during the sliding process, reducing the amount of subsequent cleaning work, and preventing residue adhesion from affecting the surface finish of the forgings. The cleaning of the rotating rollers and the lower module can be completed through the air jet pipe, without the need for additional cleaning structures, thus reducing the production cost of the device.

[0021] The molding component 22 includes two sets of third electric telescopic rods 222 respectively fixedly connected to the inner walls of both sides of the insert groove 211.

[0028] A hydraulic unit 12 is installed on the upper end of the die forging machine body 11, and an upper die 13 is fixedly installed on the lower end of the hydraulic unit 12.

The hydraulic unit 12 can control the upper die 13 to close with the mounting block 21 and the lower module 221, thereby realizing die forging.
[0029] The adjusting assembly 3 includes a linear slide 31 disposed on one side of the die forging machine body 11. The lower end of the linear slide 31 is supported by a fixed frame. A rotating part 32 is fixedly connected to the slide of the linear slide 31. A fixed sleeve plate 33 is fixedly connected to the upper end of the rotating part 32. A movable plate 34 is slidably connected to one end of the fixed sleeve plate 33. A first electric telescopic rod 35 is fixedly connected between the end of the movable plate 34 and the inner wall of the fixed sleeve plate 33. Two sets of second electric telescopic rods 41 are both disposed through the fixed sleeve plate 33. The first electric telescopic rod 35 is used to adjust the horizontal position of the two sets of unloading assemblies 4. The rotating part 32 is used to drive the fixed sleeve plate 33, the rotating part 32 and the unloading assembly 4 to rotate.
[0030] In this invention, during the die forging production of the butterfly valve core, a release agent is sprayed into the cavity through the release agent nozzle 44. Then, the trapezoidal insert strip 432 is separated from the engaging strip 233 by the second electric telescopic rod 41. The blanking assembly 4 is moved to a position where it no longer overlaps with the lower die assembly 2 by the linear slide 31. The blank is then placed in the cavity at the upper end of the lower module 221. The upper die 13, mounting block 21, and lower module 221 are then closed by the hydraulic unit 12 to achieve die forging. After die forging, the upper die 13 is raised and reset. The two sets of second electric telescopic rods 41 are moved above the two sets of lower modules 221 by the linear slide 31, aligning the trapezoidal insert strip 432 with the engaging strip 233. The trapezoidal insert strip 432 is then embedded into the engaging strip 233 by the second electric telescopic rod 41. Gas is injected into the connecting pipe 235 and the gas flow channel 224 through the connecting pipe 24. Compressed gas can enter the cavity through multiple sets of micropores, thereby forming a uniform gas film on the contact surface between the valve core forging and the cavity, overcoming the high-temperature adhesion and adsorption force. Subsequently, the two sets of transmission plates 431 move closer to each other, and the L-shaped embedding plate 434 is embedded in the locking groove 225. When the transmission plate 431 moves, the connecting plate 232 pushes the piston rod 234 to force the air inside the connecting pipe 235 into the gas flow channel 224, so that the gas inside the gas flow channel 224 is compressed again, thereby increasing the pressure inside the gas flow channel 224 instantaneously. This enables the gas discharged from the micropores to more quickly lift the valve core forging, achieving contactless automatic demolding. Compared with ejector rod demolding, this invention can avoid surface indentations and ejector rod pits on the valve core forging, effectively improving the production quality of the butterfly valve core. At the same time, the high-pressure gas can clear the micropores during gas demolding, reducing the possibility of micropore blockage. After the transmission plate 431 is inserted into the engaging groove 225, the limiting block 223 is separated from the lower module 221. At this time, the lower module 221 is clamped and fixed by two sets of L-shaped insert plates 434. Then, the lower module 221 is separated from the insert groove 211. The linear slide table 31 moves the feeding assembly 4 and the lower module 221 away from the mounting block 21. Then, the rotating part 32 rotates the fixing sleeve 33 to a position parallel to the long side of the belt conveyor 5. Then, the two sets of lower modules 221 and the two sets of flipping sliding assemblies 6 are placed alternately. Then, the first electric telescopic rod 35 moves the lower module 221 between the support plate 621 and the collection box 64. At this time, the striking block at the end of the fourth electric telescopic rod 622 contacts the upper surface of the lower module 221. The valve core forging is limited by the support plate 621 and the lower module 221. Then, the lower module 221 is rotated by the motor 433. Simultaneously, the second electric telescopic rod 41 and the first electric telescopic rod 35 are adjusted, causing the lower module 221 to rotate and push the support plate 621 to rotate 180 degrees. During this process, the mounting housing 631 and the rotation damper 632 provide resistance, keeping the striking block and the lower module 221 in contact, thus maintaining the limitation on the butterfly valve core. Subsequently, the lower module 221 moves back to above the collection box 64. During the resetting process, the support plate 621 is pressed down by the gravity of the valve core forging and continues to rotate slowly, causing one side of the support plate 621 to contact the belt of the belt conveyor 5. The valve core forging can then self-support... The plate 621 slides onto the belt of the belt conveyor 5 for transport without clamping, thus avoiding surface damage such as indentations and scratches on the thinner parts of the valve core forging caused by clamping and movement. This improves the appearance quality of the valve core forging. When the valve core forging slides, the multiple sets of rotating rollers 624 reduce the resistance during sliding. Simultaneously, due to the gaps between the multiple sets of rotating rollers 624, forging residue on the valve core forging can fall into the collection groove 623, achieving separation of forging residue from the valve core forging. After the lower module 221 is reset, the motor 433 rotates the lower module 221 180 degrees, allowing the forging residue in the cavity to fall into the collection box 64, and then through the air jet pipe... Gas is sprayed into the cavity through the nozzle 65, which can blow away the residue and clean the cavity. Then, the lower module 221 is placed back into the embedding groove 211 through the linear slide 31, the rotating part 32, and the first electric telescopic rod 35. The lower module 221 is fixed by the limiting block 223 to facilitate subsequent die forging. During the resetting process of the lower module 221, the support plate 621 will also slowly reset under the action of the rotation damper 632 and the torsion spring 633. Then, gas is sprayed into the rotating roller 624 through the nozzle 65 to clean the rotating roller 624. The cleaning of the rotating roller 624 and the lower module 221 can be completed by the nozzle 65, without the need for additional cleaning structures, which reduces the production cost of the device.
