In order to facilitate the forging preparation of flanges, we propose a flange forging equipment and forging method.

[0003] After searching, the Chinese patent with the patent publication number CN118875200A discloses a flange forging production equipment, which includes a base, an L-shaped plate arranged on the top of the base, a forging mechanism, the forging mechanism is used to forge the flange, a clamping mechanism, the clamping mechanism is used to clamp and fix the flange, and a shock-absorbing mechanism. When the flange is clamped and processed in the equipment, the high-pressure water pump, the hydraulic telescopic pipe, the forging hammer, the transmission pipe, the telescopic pipe, the lubricating oil brush, the driving motor, the sealing chamber, the electric push rod, the rotating rod, the rotating chamber and the support plate can be used to lubricate, maintain and remove waste when the forging hammer is forging the flange. Garbage cleaning, a Chinese patent with patent announcement number CN117564206B discloses a flange forging device, which includes a base, a support body fixedly installed on the back of the base, a power hammer fixedly connected to the upper part of the support body, and an installation cavity opened inside the base. When in use, through the setting of the spraying mechanism, the air supply mechanism makes the shaft pass through the mold and lift it to the highest position. The two rectangular through holes on the connecting pipe will be connected with the guide ring, and the powdered release agent in the material cavity will pass through the rectangular through holes.

The forging mechanism is used for stamping and forging the blank strip 1. The forging mechanism includes a vertical hydraulic forging machine 12 and a lateral roll forging structure. The vertical hydraulic forging machine 12 is installed on the main frame 2, and a hammer block 13 is installed at the bottom end of the lifting arm of the vertical hydraulic forging machine 12. The hammer block 13 is used for forging the blank strip 1. The lateral roll forging structure includes a plurality of radial sliders 14.

Through the design of the forging mechanism, the matching wound and formed blank strips 1 are forged to achieve mutual connection between adjacent blank strips 1, and the winding of the filaments is integrated into the forging operation to achieve the connection and forming of the coiled filaments, and the annular structure is directly formed while the flange is manufactured, which reduces the material removed by the punching part and has a high material utilization rate.

[0038] It should be further explained that the bottom end of the hammer block 13 is provided with two spacing grooves 19, and the two spacing grooves 19 are respectively slidably connected with the inner push block 20 and the outer push block 21. The bottom ends of the inner push block 20 and the outer push block 21 are provided with arc-shaped anti-slip grooves 39 to improve the contact friction between the blank strip 1 and ensure the effective push of the blank strip 1. The inner push block 20 and the outer push block 21 are respectively rotatably connected with the inner push frame 22 and the outer push frame 23. The inner push frame 22 and the outer push frame 23 are respectively rotatably connected in the two spacing grooves 19. The two spacing grooves 19 are fixedly connected with a push-out spring group 24. The two push-out spring groups 24 are respectively connected to the inner push block 20 and the outer push block 21.

There are two vertical connecting blocks 26 that are slidably connected, and four horizontal connecting blocks 25 are fixedly connected to the four vertical connecting blocks 26 respectively. When the hammer block 13 acts on the wound billet strip 1, it will squeeze the gap between the billet strips 1, and then form a tight squeeze on the wound billet strip 1. Since the billet strip 1 has been heated by the electromagnetic induction ring 11 before being wound, the adjacent parts of the forged billet strip 1 will form a relative adhesion formation, and since the billet strip 1 supports the inner push block 20 and the outer push block 21, during the process of the hammer block 13 hammering the billet strip 1, the inner push block 20 and the outer push block 21 will move relative to the hammer block 13. Due to the rotation of the inner push frame 22 and the outer push frame 23, the inner push block 20 acting on the billet strip 1 will make the billet strip 1 is pushed inward while being vertically extruded, and the outward pushing block 21 acting on the blank strip 1 will push the blank strip 1 outward while being vertically extruded. An inverted gantry 27 is fixedly connected to the main frame 2, and an electric lifting rod 28 is installed at the bottom end of the inverted gantry 27. A lifting column 29 is installed on the lifting rod of the electric lifting rod 28. The lifting column 29 passes through the central tube 9. The lifting column 29 is fixedly connected to the side extension frame, and a top pressure roller 30 is rotatably connected in the side extension frame to form a flat ring surface on the top of the blank strip 1 after winding and forging. An auxiliary bonding structure is installed on the main frame 2. The auxiliary bonding mechanism is used for the lateral bonding of the blank strip 1 relative to the central tube 9. An electromagnetic induction ring 11 for heating the blank strip 1 is installed on the main frame 2. The auxiliary bonding structure includes The rotating column 31 and the electric adjustment rod 32 are rotatably connected to the main platform 2, and the electric adjustment rod 32 is installed in the main platform 2.

The rotating column 31 is fixedly connected to the hanging bracket 36, and the double hangers 35 are rotatably connected to the hanging bracket 36. A return spring 37 is connected between the hanging bracket 36 and the double hangers 35. Through the design of the auxiliary fitting structure, the blank strip 1 can be matched to form different winding radii, so that the blank strip 1 can be wound into the blank size of the flange ring, which is more practical. The center tube 9 is fixedly connected to the outer expansion support ring 38.The bottom ends of the side pressure wheel 18 and the side push wheel 34 are both higher than the top end of the outer support ring 38, which can provide bottom support for the wound blank strip 1. In addition, the distance between the side pressure wheel 18 and the top end of the outer support ring 38 and the distance between the bottom end of the side push wheel 34 and the top end of the outer support ring 38 are both less than half the height of the blank strip 1, reducing the possibility of the blank strip 1 escaping.

[0039] The first servo motor 6, the second servo motor 10, the electric telescopic rod 7, the electromagnetic induction ring 11, the vertical hydraulic forging machine 12, the electric lifting rod 28 and the electric adjustment rod 32 in this embodiment are all conventional equipment purchased on the market and well known to those skilled in the art. In the present invention, we only use them and do not improve their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of the instruction manual, and will not be described in detail here.

[0040] To sum up, the working principle of the flange forging equipment and forging method is that when in use, the flange forging equipment is first placed at the desired location, and the positioning bolts are installed at the placement location according to the position of the positioning anchor hole 40. Then, the main stand 2 is positioned at the placement location through the positioning installation between the positioning bolts and the positioning anchor hole 40. A control circuit is installed to match the first servo motor 6, the second servo motor 10, the electric telescopic rod 7, the vertical hydraulic forging machine 12, the electric lifting rod 28 and the electric adjusting rod 32. The operation of the first servo motor 6, the second servo motor 10, the electric telescopic rod 7, the vertical hydraulic forging machine 12, the electric lifting rod 28 and the electric adjusting rod 32 can be controlled by the control circuit. Then, the power supply of the electromagnetic induction ring 11 is turned on, and the blank strip 1 passes through the area between the drive guide wheel 5 and the positioning wheel 8. In this process, the electric telescopic rod 7 is controlled to realize The movement control of the sliding frame 3 relative to the fixed frame 4 then forms a gap adjustment between the driving guide wheel 5 and the positioning wheel 8, so that the blank strip 1 can bend after passing through the gap, and the blank strip 1 passing through the gap between the driving guide wheel 5 and the positioning wheel 8 will enter the heating area of ​​the electromagnetic induction ring 11, and the electromagnetic induction ring 11 realizes the heating of the blank strip 1. The heated blank strip 1 will be close to the center tube 9, and the auxiliary fitting structure controls the cutting-in of the blank strip 1 relative to the center tube 9. At this time, the electric adjustment rod 32 is powered on to realize the movement drive of the drive rod 33, and the movement of the drive rod 33 realizes the rotation drive of the rotating column 31, thereby realizing the rotation drive of the suspension bracket 36, and then realizes the position adjustment of the two side push wheels 34 relative to the center tube 9, and then forms further bending adjustment on the blank strip 1 close to the center tube 9, so that the blank strip 1 can better form bending and fitting relative to the center tube 9.

[0041] Furthermore, the rotation control of the center tube 9 is realized by controlling the operating state of the second servo motor 10, thereby forming the winding control of the blank strip 1 relative to the center tube 9. The rotation of the center tube 9 is coordinated with the rotation of the driving guide wheel 5 to realize the winding positioning of the blank strip 1 at different diameter positions of the center tube 9. In this process, if the linear speed of the outer cylinder surface of the center tube 9 increases within a certain range relative to the linear speed of the outer wheel surface of the driving guide wheel 5, the blank strip 1 forms a winding with a smaller diameter relative to the annular surface of the center tube 9, and if the linear speed of the outer cylinder surface of the center tube 9 decreases within a certain range relative to the linear speed of the outer wheel surface of the driving guide wheel 5, the blank strip 1 forms a winding with a larger diameter relative to the annular surface of the center tube 9, so that the blank strip 1 forms a surrounding covering winding outside the center tube 9. The winding process of the blank strip 1 The middle forging mechanism performs a forging operation on the wound billet strip 1. As the billet strip 1 is wound continuously, the vertical hydraulic forging machine 12 operates to control the hammer block 13 to perform a reciprocating lifting motion, so that the hammer block 13 performs a forging operation on the wound billet strip 1. During this process, the area where the hammer block 13 contacts the billet strip 1 will cause the billet strip 1 to form a forging extrusion in the vertical direction, thereby causing the upper and lower adjacent billet strips 1 to be squeezed and adhered. Under the support of the billet strip 1, the inner push block 20 and the outer push block 21 will form a relative upward motion relative to the hammer block 13, and the inner push block 20 that is moving upward will move radially close to the center of the circle under the action of the inner push frame 22, while the outer push block 21 that is moving upward will move radially away from the center of the circle under the action of the outer push frame 23. The blank strip 1 in the annular winding state is offset in the horizontal direction, thereby improving the overall connectivity of the blank strip 1 wound at the same height. During operation, the electric lifting rod 28 operates to realize the height control of the lifting column 29, so that the top pressure roller 30 trims the top ring surface of the blank strip 1 forged by the hammer block 13, and at the same time, multiple side pressure wheels 18 will extrude and trim the outer ring surface of the wound blank strip 1. After the quality of the wound blank strip 1 meets the size of the flange to be prepared, the feeding of the blank strip 1 is stopped, and then the first servo motor 6 stops running, driving the guide wheel 5 to stop rotating, and cutting the blank strip 1 through an external cutting device, so that the center tube 9 can drive the blank strip 1 wound thereon to form a rotational motion, and continuously strike the winding through the hammer block 13. The top of the blank strip 1 is trimmed by the top pressure roller 30 and multiple side pressure wheels 18 at the same time. During the trimming process, the electric control rod 16 is powered on to drive the radial slider 14 close to the center cylinder 9, so that the distance between the side pressure wheel 18 and the center cylinder 9 is reduced, which plays a role in controlling the width adjustment of the annular structure of the wound blank strip 1 and the inner diameter and outer diameter of the annular structure. In this process, the inner diameter and outer diameter of the flange ring will gradually increase, and the greater the reduction in the distance between the side pressure wheel 18 and the center cylinder 9, the smaller the difference between the inner diameter and outer diameter of the flange, and the larger the inner diameter and outer diameter of the flange, until the flange meets the design expectations, that is, the forging preparation of the flange is realized. After the forging is completed, the second servo motor 10 stops driving the center cylinder 9.The flange can be removed. Since the flange undergoes expansion of its inner and outer diameters during the forging process, it is more convenient to remove it from the center tube 9. After that, the flange can be finely processed by turning and drilling. Since the electromagnetic induction ring 11 will heat the blank strip 1 to be wound during the flange forging process, the blank strip 1 after winding is still at a relatively high temperature, meeting the requirements of forging connection. In order to ensure the high temperature state of the blank strip 1 after winding, the blank strip 1 can be equipped with an insulation structure or a secondary heating structure as appropriate to improve the practicality of the equipment and cope with extreme situations where the wound blank strip 1 dissipates heat too quickly in special environments.

8. A flange forging method, characterized in that: A flange forging device according to any one of claims 1 to 7 is used, comprising the following steps: S1. When in use, first install a control circuit for the first servo motor, the second servo motor, the electric telescopic rod and the forging mechanism, and the operation control of the first servo motor, the second servo motor, the electric telescopic rod and the forging mechanism can be realized through the control circuit; S2. Then, the electromagnetic induction ring is powered on, and the blank strip is passed through the area between the driving guide wheel and the positioning wheel. During this process, the movement of the sliding frame relative to the fixed frame is controlled by controlling the electric telescopic rod, thereby adjusting the gap between the driving guide wheel and the positioning wheel, so that the blank strip can be bent when passing through the gap; S3. The blank strip passing through the gap between the driving guide wheel and the positioning wheel enters the heating area of ​​the electromagnetic induction ring. The electromagnetic induction ring heats the blank strip. The heated blank strip moves closer to the center tube. The auxiliary fitting structure controls the cutting of the blank strip relative to the center tube. At the same time, the rotation of the center tube is achieved by controlling the operating state of the second servo motor. S4. The center tube rotates in conjunction with the driving guide wheel to realize the winding and positioning of the blank strip at different diameter positions of the center tube. During the winding process of the blank strip, the forging mechanism performs a forging operation on the wound blank strip to realize the forging preparation of the flange.
