Description

Technical Field

[0001] The invention relates to the technical field of flange processing, in particular to a forging device for flange processing. Background Art

[0002] Flange forging is a flange made by forging process, and its mechanical properties are better than other types of flanges. The raw material of forged flange is generally a tube billet, which is cut and hammered continuously to eliminate defects such as segregation and looseness in the steel ingot. During the forging process, the metal billet undergoes plastic deformation in the forging die under the action of the forging machine, thereby obtaining a flange with specific mechanical properties, shape and size.

[0003] During the forging process of the flange, oxygen in the air will react chemically with the surface of the metal blank to form oxide scale. The oxide scale will make the surface of the forging rough, affecting the quality and appearance of the forging and increasing the deformation energy consumption. The oxide scale has a high hardness and will accelerate the wear of the forging die and reduce its service life. When the flange is taken out after forging, more oxide scale will be left in the forging die. The oxide scale will affect the quality of the forging and the surface of the die cavity and must be removed in time. Compressed air is usually used to blow away the oxide scale in the die. Currently, the forging die is fixed on the forging table with the opening facing upward. During the blowing process, some oxide scale will be affected by its own gravity, and there are dead corners in the forging die. As a result, during the compressed air blowing process, the oxide scale cannot be completely blown upward from the bottom of the forging die to the outside of the forging die, resulting in a general cleaning effect of the oxide scale in the forging die, affecting the forging quality of the flange. Summary of the invention

[0004] The present invention provides a forging device for flange processing, which can realize the purpose of inverting the forging die in the cleaning box, facilitate the oxide scale in the forging die during the cleaning process, and make the oxide scale be affected by its own gravity and automatically fall into the cleaning box, thereby reducing the residual amount of oxide scale in the forging die and improving the cleaning effect of the oxide scale. It solves the problem mentioned in the above background technology that the current forging die is fixed on the forging table with the opening facing upward, and some oxide scale will be affected by its own gravity during the blowing process, and there is a dead corner for blowing in the forging die, so that during the compressed air blowing process, the oxide scale cannot be completely blown upward from the bottom of the forging die to the outside of the forging die, resulting in a general cleaning effect of the oxide scale in the forging die, affecting the forging quality of the flange.

[0016] The present invention has the following beneficial effects:

[0017] 1. In the forging device for flange processing, when the rotating shaft on the support frame is fixedly connected to the rotating plate, the first servo motor drives the rotating shaft to rotate, so as to achieve the purpose of driving the forging die on the rotating plate to flip, so that the flange in the forging die falls into the blanking plate on the one hand, and the flange can be turned upside down in the cleaning box after the blanking is completed on the other hand, which is convenient for the oxide scale in the forging die to be cleaned, so that the oxide scale is affected by its own gravity and can automatically fall into the cleaning box, thereby reducing the residual amount of oxide scale in the forging die and improving the cleaning effect of the oxide scale. The servo electric cylinder fixed on the rotating plate can drive the push plate slidably connected in the forging die to move, so that the flange can be quickly separated from the forging die during the inverted process of the forging die, thereby avoiding obstacles to the cleaning of the oxide scale.

[0018] 2. In the forging device for flange processing, the cooling water tank can be used to water-cool the forged flange to reduce the temperature of the flange. The blanking plate connected to one side of the cooling water tank can be used to receive the blanked flange when the forging die is flipped, so as to avoid the flange from hitting the cleaning box when it falls. The limit bar is used to prevent the blanking plate from tilting toward the cleaning box. The moving component can adjust the position of the blanking plate after the blanking plate receives the flange, so as to move the blanking plate and the flange to one side of the cleaning box to avoid obstruction to the cleaning of the forging die. The L-shaped interference rod connected to the guide block on the cleaning box can interfere with the L-shaped interference rod during the flipping of the rotating plate, so as to achieve the purpose of interfering with the seesaw assembly when the L-shaped interference rod moves downward, so as to prompt the seesaw assembly to push the L-shaped top rod upward, prompt the blanking plate to rotate, and the flange automatically slides to the cooling water tank for cooling, so as to facilitate the subsequent processing of the flange after cooling.

[0019] 3. In the forging device for flange processing, the base in the cleaning box is slidably connected to the hollow column. When the flange enters the cooling water tank, the weight is increased, and the cooling water tank can drive the fixed third friction rod to move downward, so that the third friction rod can be colliding with the first friction wedge in the connecting seat. The damping rod fixed between the cooling water tank and the connecting seat can slow down the speed of the third friction rod moving downward and colliding. When the first friction wedge drives the first friction rod to push the second friction rod on the strip friction plate to move horizontally, the second friction rod can drive the second friction wedge to collide with the hollow column during the horizontal movement. After the forging die is buckled, the hollow column can drive the first hollow rod and the cleaning head fixed on the upper end of the first hollow rod to move vertically, so that the cleaning head can smoothly enter the interior of the forging die. The rotating assembly can drive several steel wire cleaning blocks fixed on the cleaning head to rotate, which is convenient for cleaning the oxide scale attached to the inner wall of the forging die, thereby improving the quality of flange forging by the forging die.

[0020] 4. In the forging device for flange processing, when the flange is cooled and taken out from the cooling water tank, the cooling water tank can be reset, so that the second conflicting wedge can be released from the conflict with the hollow column, and the cleaning head can be moved downward. At the same time, the purpose of spraying lubricating oil can be achieved through the nozzle installed on the cleaning head. When the lubricating oil is sprayed on the inner wall of the forging die, the die surface can be effectively lubricated to prevent the appearance of oxide scale inside the die and improve the demoulding effect of the flange. The sponge brush can be installed through a plurality of first conflicting frames arranged in the cleaning head. When the second conflicting frame and the second conflicting ring fixed on the second hollow rod are released from conflict, the first conflicting ring fixed on the second hollow rod can be moved downward to conflict with the first conflicting frame, so that the first conflicting frame drives the sponge brush to move horizontally and against the inner wall of the forging die. During the rotation of the cleaning head, the sponge brush can be evenly applied with the lubricating oil. At the same time, the first conflicting frame conflicts with the second strip sheet through the first strip sheet during the movement, so that the nozzle is swung on the cleaning head, which can improve the spraying effect of the lubricating oil.

[0033] When flange forging is finished, refer to Figure 1-Figure 3 , the first servo hydraulic cylinder 2 fixed on the forging table 1 drives the forging head 3 to disengage from the forging die 7 and move upward, and the first servo motor 8 drives the rotating shaft 5 to rotate on the support frame 4, and the rotating shaft 5 can drive the rotating plate 6 and the forging die 7 fixed on the rotating plate 6 to flip. During the flipping process, the servo electric cylinder 11 fixed on the rotating plate 6 can drive the push plate 10 slidably connected in the forging die 7 to move, so that the flange quickly disengages from the forging die 7, so that the detached flange falls on the blanking plate 13 to complete the unloading. When the moving component drives the blanking plate 13 to move to one side of the cleaning box 9, the rotating plate 6 continues to flip, and the purpose of inverting the forging die 7 in the cleaning box 9 can be achieved, which is convenient for the oxide scale in the forging die 7 during the cleaning process, and the oxide scale is automatically affected by its own gravity and falls into the cleaning box 9, thereby reducing the residual amount of oxide scale in the forging die 7 and improving the cleaning effect of the oxide scale.

For details, please refer to Figures 1 to 8 A cooling water tank 12 is provided at one end of the cleaning box 9, and a blanking plate 13 is rotatably connected to one side of the cooling water tank 12. A limiting strip 14 is fixed on the cooling water tank 12, and the blanking plate 13 is against the limiting strip 14. A connecting seat 15 is provided under the cooling water tank 12. The cooling water tank 12 is elastically connected to the connecting seat 15 through a first spring 16, and a moving component is connected to the bottom of the connecting seat 15.

[0035] A guide block 17 is fixed on the cleaning box 9, an L-shaped resistance rod 18 is slidably connected to the guide block 17, a second spring 19 is connected between the L-shaped resistance rod 18 and the guide block 17, an L-shaped push rod 20 is slidably connected to the cleaning box 9, a third spring 21 is connected between the L-shaped push rod 20 and the cleaning box 9, and a rocker assembly is provided between the L-shaped resistance rod 18 and the L-shaped push rod 20.

One end of the seesaw 92 abuts against the L-shaped abutting rod 18, and the other end of the seesaw 92 abuts against the L-shaped ejector rod 20.

[0038] After the forged flange is blanked, it needs to be cooled. Refer to Figure 1-Figure 4 , when the flange falls from the forging die 7 onto the blanking plate 13, the second servo hydraulic cylinder 153 in the moving component pushes the connecting seat 15 to move horizontally on the two sliding rods 152 fixed on the U-shaped seat 151, so that the connecting seat 15 drives the cooling water tank 12 and the blanking plate 13 to move to one side of the cleaning box 9, avoiding hindering the cleaning of the forging die 7. When the rotating plate 6 continues to flip, it can abut against the L-shaped abutting rod 18, causing one end of the L-shaped abutting rod 18 to move downward, and the second spring 19 to store energy. During the downward movement of the L-shaped abutting rod 18, it can abut against one end of the seesaw 92, causing the seesaw 92 to rotate on the rotating rod 91, and the first torsion spring 93 to store energy. The other end of the seesaw 92 can abut against the L-shaped ejector rod 20 during the rotation process, causing the L-shaped ejector rod 20 to slide upward, and the third spring 21 to store energy, thereby lifting the blanking plate 13, so that the flange on the blanking plate 13 can slide into the cooling water tank 12 for cooling, facilitating the subsequent processing of the cooled flange.

[0039] Embodiment 3, this embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figures 1 to 8 , a base 22 is fixed in the cleaning box 9. A hollow column 23 is slidably connected to the base 22. A fourth spring 24 is connected between the hollow column 23 and the base 22. A first hollow rod 25 is rotatably connected to the hollow column 23. A cleaning head 26 is fixed at the upper end of the first hollow rod 25. A plurality of wire cleaning blocks 261 are fixed on the circumferential surface of the cleaning head 26. A rotating component for driving the first hollow rod 25 to rotate is arranged on the hollow column 23. The rotating component includes a second servo motor 231. The second servo motor 231 is fixed on the hollow column 23, and a first gear 232 is fixed on the motor shaft of the second servo motor 231. A second gear 233 is fixed on the first hollow rod 25. The second gear 233 meshes with the first gear 232.

[0040] A first interference wedge 27 is provided in the connecting seat 15, and a first interference rod 28 is fixed on the first interference wedge 27.

[0042] In order to improve the quality of flange processing, it is necessary to remove the oxide scale on the inner wall of the forging die 7 that is difficult to fall off. Figure 4-Figure 6 When the flange is cooled in the cooling water tank 12, the weight of the cooling water tank 12 is increased, so that the cooling water tank 12 drives the third resistance rod 48 to move downward, and the first spring 16 accumulates force, so that the third resistance rod 48 can be prevented from interfering with the first resistance wedge 27. The damping rod 30 fixed between the cooling water tank 12 and the connecting seat 15 can slow down the speed of the third resistance rod 48 moving downward and interfering. The first resistance wedge 27 drives the first resistance rod 28 to push the second resistance rod 31 on the strip resistance plate 33 to move horizontally, so that the fifth spring 29 and the sixth spring 32 accumulate force. The second resistance wedge 34 fixed on the second resistance rod 31 can be prevented from interfering with the hollow column 23 during the movement, so that the hollow column 23 can be prevented from interfering with the hollow column 23 on the base 22. The fourth spring 24 accumulates force. After the forging die 7 is inverted, the hollow column 23 drives the first hollow rod 25 and the cleaning head 26 fixed on the upper end of the first hollow rod 25 to move vertically, so that the cleaning head 26 can smoothly enter the forging die 7. With the cooperation of the second servo motor 231 of the rotating assembly, the first gear 232 drives the second gear 233 to rotate, so that the first hollow rod 25 drives the cleaning head 26 to rotate, so that the several steel wire cleaning blocks 261 fixed on the cleaning head 26 rotate, which is convenient for cleaning the oxide scale attached to the inner wall of the forging die 7, thereby improving the quality of flange forging of the forging die 7. The cleaned oxide scale can automatically fall into the cleaning box 9, which greatly improves the efficiency and speed of cleaning the oxide scale in the forging die 7.

[0043] Embodiment 4: This embodiment is an improvement made on the basis of Embodiment 3.

[0044] A second abutment ring 44 is fixed on the second hollow rod 41 , one side of the second abutment ring 44 abuts against a second abutment frame 45 , the second abutment frame 45 is elastically connected to the hollow column 23 via a ninth spring 46 , one end of the second abutment frame 45 abuts against the second abutment wedge 34 , and a swivel joint 47 is fixed to the lower end of the second hollow rod 41 .

[0045] In order to prevent the appearance of oxide scale inside the forging die 7 and improve the demoulding effect of the flange, it is necessary to apply lubricating oil after the oxide scale is cleaned. Figure 5-Figure 8Since the second interfering wedge block 34 in the moving state interferes with the hollow column 23, the hollow column 23 can drive the first hollow rod 25 and the cleaning head 26 fixed on the upper end of the first hollow rod 25 to move vertically, so that the cleaning head 26 can smoothly enter the forging die 7. At the same time, the second interfering wedge block 34 also interferes with the second interfering frame 45 on the hollow column 23 during the movement process, and the ninth spring 46 accumulates force, so that the second interfering frame 45 is subjected to the interference force and the second hollow rod 41 is connected. The fixed second contact ring 44 contacts, so that the second hollow rod 41 drives the first contact ring 42 to move vertically, and the eighth spring 43 accumulates force to release the contact with the first contact frame 35, so that the sponge brush 37 can be retracted and not contact the inner wall of the forging die 7. When the flange is cooled and taken out from the cooling water tank 12, the cooling water tank 12 moves upward to reset, which indirectly realizes that the second contact wedge 34 is released from the hollow column 23 and the second contact frame 45 respectively, so that the hollow column 23 drives the first hollow The rod 25 and the cleaning head 26 fixed on the upper end of the first hollow rod 25 move downward, and the eighth spring 43 releases its elastic force, prompting the second hollow rod 41 to drive the first contact ring 42 to move downward and contact with the first contact frames 35 at the same time, so that the first contact frame 35 drives the sponge brush 37 to move horizontally and contact the inner wall of the forging die 7. At the same time, the first strip piece 39 fixed on the first contact frame 35 can achieve the purpose of contacting with the second strip piece 40 on the nozzle 38 during the movement, prompting the nozzle 38 to The cleaning head 26 swings, and the second torsion spring 381 accumulates force. The lubricating oil delivery equipment is connected to the rotating joint 47 fixed at the lower end of the second hollow rod 41, so that the second hollow rod 41 can deliver the lubricating oil to the nozzle 38 through the pipeline during the rotation. When the nozzle 38 swings, the spraying effect of the lubricating oil can be improved. During the rotation of the cleaning head 26, the lubricating oil can be evenly applied to the inner wall of the forging die 7 through the sponge brush 37, which can prevent oxidation inside the forging die 7 and improve the flange forging quality.
