Description

Technical Field

[0001] The invention relates to the technical field of flange component production equipment, and in particular to a hydraulic press equipment and a forging method suitable for forging blanks of various flanges. Background Art

[0002] Flange, also known as flange plate, is a part that connects pipes, valves, and equipment. It is usually composed of a circular metal ring with holes and bolt holes, allowing the various parts to be connected by bolts. Flanges are usually used in industrial fields, such as pipeline systems, to connect different parts to ensure sealing and safety. It can be designed and produced according to different needs and standards.

[0003] The die forging process is a key step in the flange production process. It is to place the heated blank in a forging die fixed on the die forging equipment for forging. Common die forging equipment includes die forging clamp hammer and hot die forging press. During the die forging process, the staff needs to use pliers or clamps to shake the forging back and forth on the side so that the forging is evenly stressed from all parts of the top to ensure the forging quality. However, the above method is not only cumbersome to operate, but also greatly increases the work intensity and workload of the staff. At the same time, the oxidized debris splashed during forging is easy to fall into the die seat, so that the outer side of the formed flange has more oxidized debris after forging and pressure, which prolongs the subsequent processing time of the flange and reduces the flange processing efficiency.

[0014] The present invention also discloses a forging method of a hydraulic press device suitable for forging a variety of flange blanks, comprising the following steps: S1: According to the size of the flange to be processed, the staff will plug the positioning rod on the lower side of the adapter die base into the positioning hole on the elastic expansion plate, place the die base, and then place the forging in the die base; S2: Control the operation of the first hydraulic cylinder, and the piston rod of the first hydraulic cylinder drives the pressure head to move up and down, so that the pressure head forges the forging in the die base; S3: When the connecting plate moves up, the rack plate is pulled by the second pull rope. When the connecting plate moves down, the rack plate moves back under the elastic pull of the second elastic telescopic rod, so that the rack plate moves back and forth on the fixed block. The rack plate meshes with the one-way gear for transmission, so that the pressure head moves down. When forging the forging, the one-way gear drives the gear ring to rotate, and the main bevel gear on the gear ring is intermittently meshed with the secondary bevel gear on the rotating rod. When the main bevel gear is meshed with the secondary bevel gear, the rotating rod reels the first pull rope through the first drum, and the first pull rope pulls the placement seat, so that the placement seat drives the die seat to shake in the fixed seat, and the position of the forging under the pressure head is adjusted, so that the pressure head forges different positions of the forging, and the forging is evenly filled into the die seat; S4: When the rack plate slides back and forth on the fixed block, the rack plate meshes with the driven gear at the same time, so that the driven gear drives the winding rod to rotate forward and reversely. When the pressure head moves up, the third pull rope is wound up to pull the wedge-shaped push block, and the fourth pull rope is released and no longer exerts force on the wedge-shaped push block, so that the wedge-shaped push block slides to the side away from the movable seat. The wedge-shaped push block no longer supports the movable seat, and the movable seat moves downward under the action of gravity. The top of the movable seat no longer presses the lower side of the mold base, and the various sub-seat bodies of the mold base are dispersed under the pull of the elastic telescopic plate; The air outlet on the connecting plate blows the dispersed die base, so that the oxidized waste chips generated when the pressure head forges the forging are blown away and away from the internal groove of the die base, and the oxidized debris falls into the waste groove or the gap between the protective plate and the placement seat; When the pressure head moves downward, the third pull rope is released and the fourth pull rope is reeled in and exerts force on the wedge-shaped push block, the wedge-shaped push block moves to the side close to the movable seat, the wedge-shaped push block pushes the bottom of the movable seat, so that the movable seat moves upward, and the wedge-shaped push block moves to the lower side of the movable seat and supports the movable seat, providing stable support for the pressure head during forging of the forging; S5: The ram reciprocates up and down to forge the forging, so that the forging is filled in the die base and formed. As the main bevel gear and the secondary bevel gear mesh for multiple cycles, when the ram and the die base are about to abut, the main bevel gear is no longer meshed with the secondary bevel gear, and the placement seat is reset under the elastic force of the first elastic telescopic rod. The placement seat is located directly below the ram, and then the ram abuts against the top of the die base. By controlling the operation of the second hydraulic cylinder, the baffle is flipped to open the concave hole at the movable seat, and then the operation of the third hydraulic cylinder is controlled to control the punching head to reciprocate up and down, and the punching head punches the forged flange forging to complete the preliminary processing of the flange forging; S6: Then the first hydraulic cylinder drives the pressure head to move up, so that the seat body is dispersed again, and the die seat and the forged flange forging are automatically separated. The staff takes out the forged flange forging and proceeds to the next processing step.

[0015] Compared with the prior art, the present invention provides a hydraulic press device and a forging method suitable for various flange die forging blanks, which has the following beneficial effects: 1. The hydraulic press equipment and forging method applicable to various flange die forging blanks can place the various positions of the forgings on the lower side of the pressure head in sequence through the swing mechanism, so as to facilitate uniform forging of various positions of the forgings. It is unnecessary for the staff to use pliers or clamps to shake the forgings back and forth, thus reducing the workload and work intensity of the staff and improving the forging efficiency of the forgings. 2. The hydraulic press equipment and forging method applicable to various flange die forging blanks realize automatic separation and combination of the die base by utilizing the upward and downward movement of the pressure head. Each time the pressure head moves upward, the die base automatically separates, which is convenient for cooperating with the air jet to blow away the waste chips generated in the die base during forging, thereby avoiding excessive waste chips from accumulating in the die base and re-combining with the forgings gradually filling the die base, reducing the processing time of subsequent flange forgings, and improving the flange processing efficiency. The upward movement of the pressure head disperses the die base, which is convenient for the automatic separation of the die base and the forgings, thereby avoiding the forgings being tightly filled in the die base under force, resulting in the forgings being difficult to demold, and improving the demolding efficiency of the forgings; 3. The hydraulic press equipment and forging method applicable to various flange die forging blanks, by arranging a waste groove on the outer seat, is convenient for receiving the waste chips generated when the forging is under pressure in the die seat, so that the waste chips are automatically discharged through the discharge channel, and a protective plate is arranged on the upper side of the positioning seat, which can protect the gear transmission parts on the one hand, and facilitate the waste chips falling on the protective plate to slide down automatically along the guide sliding surface on the other hand, so as to ensure the cleanliness of the working surface of the equipment and facilitate the cleaning and collection of the waste chips; 4. The hydraulic press equipment and forging method suitable for various flange die forging blanks can facilitate rapid replacement of the die base by docking the die base with the placement base using a positioning rod, and can process a variety of different flanges. After the pressure head cooperates with the die base to forge the forged piece, the punching head can be used to punch holes in the forged flange forging. The forming and punching steps are performed using the same die base, and there is no need to transfer the forging piece or replace the processing equipment, which is convenient for improving the processing efficiency of the flange forging piece.

The ram 4 drives the connecting plate 401 to slide on the outside of the guide column 101. When the ram 4 forges the forging, the swing mechanism works automatically, and the various positions of the forging are placed on the lower side of the ram 4 in turn through the swing mechanism, which is convenient for uniform forging of various positions of the forging. There is no need for the staff to use pliers or clamps to shake the forging back and forth on the side, which reduces the workload and work intensity of the staff and improves the forging efficiency of the forging.

[0022] Example 2: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 A hydraulic press device suitable for forging various flange blanks. On the basis of Example 1, further, the swing mechanism includes a rotating rod 7 rotatably connected to a fixed seat 502, a first drum 701 arranged on the rotating rod 7, and a first pull rope 702 wound around the first drum 701, the end of the first pull rope 702 away from the first drum 701 is connected to the fixed seat 502, and a plurality of first elastic telescopic rods 8 are evenly arranged in a circle between the placement seat 503 and the fixed seat 502.

[0023] Furthermore, a limit frame 9 is provided on the fixed block 501, and a rack plate 901 is slidably connected in the limit frame 9, a second elastic telescopic rod 10 is provided between the rack plate 901 and the fixed block 501, one end of the rack plate 901 is connected to a second pull rope 902, and the end of the second pull rope 902 away from the rack plate 901 passes through the fixed block 501 and is connected to the connecting plate 401, a one-way gear 11 meshing with the rack plate 901 is rotatably connected to the fixed block 501, a gear ring 12 meshing with the one-way gear 11 is rotatably connected to the fixed seat 502, a main bevel gear 121 is provided on the gear ring 12, and a secondary bevel gear 703 meshing with the main bevel gear 121 is provided on the rotating rod 7.

[0024] Furthermore, a plurality of vacant portions 1211 are formed on the main bevel gear 121 , and the plurality of vacant portions 1211 separate the main bevel gear 121 into a plurality of arc-shaped bevel teeth.

[0025] Specifically, after the forging is placed on the die base 6, the first hydraulic cylinder 3 is controlled to operate, and the piston rod of the first hydraulic cylinder 3 drives the ram 4 to move reciprocatingly up and down, so that the ram 4 forges the forging in the die base 6. When the connecting plate 401 moves up, the rack plate 901 is pulled by the second pull rope 902. When the connecting plate 401 moves down, the rack plate 901 moves back under the elastic pull of the second elastic telescopic rod 10, so that the rack plate 901 moves back and forth on the fixed block 501. The rack plate 901 is meshed with the one-way gear 11 for transmission. When the ram 4 moves down to forge the forging, the one-way gear 11 drives the gear ring 12 to rotate, and the main bevel gear 121 on the gear ring 12 is intermittently meshed with the secondary bevel gear 703 on the rotating rod 7. When the main bevel gear 121 is meshed with the secondary bevel gear 703, the rotating rod 7 retracts the first pull rope 702 through the first drum 701. The first pull rope 702 pulls the placement seat 503, so that the placement seat 503 drives the die base 6 to rock in the fixed seat 502, and adjusts the position of the forging on the lower side of the ram 4, so that the ram 4 forges the forging at different positions, and the forging is evenly filled into the die base 6. There is no need for the staff to use pliers or clamps to rock the forging back and forth on the side, which reduces the workload and work intensity of the staff and improves the forging efficiency of the forging. It should be noted that the number of meshing teeth of the main bevel gear 121 and the secondary bevel gear 703 is set according to actual conditions. After the ram 4 forges the forging multiple times, when the ram 4 is about to abut against the die base 6, the main bevel gear 121 no longer meshes with the secondary bevel gear 703, and the placement seat 503 is reset under the elastic force of the first elastic telescopic rod 8, and the placement seat 503 is located directly below the ram 4, and then the ram 4 abuts against the top of the die base 6.

[0026] Example 3: Reference Figure 1 , Figure 2 and Fig.10 , a hydraulic press equipment suitable for forging various flange blanks. On the basis of Example 2, further, the placement seat 503 includes an outer seat 5031 connected to the first elastic telescopic rod 8 and the first pull rope 702, and a movable seat 5032 slidably connected to the outer seat 5031, the die base 6 is arranged on the movable seat 5032, the outer seat 5031 is provided with a waste trough 13 for collecting waste chips and a movable groove 14 for sliding the movable seat 5032, and the placement seat 503 is provided with a discharge channel connected to the waste trough 13.

[0027] Furthermore, a protective plate 21 is fixedly provided on the top of the positioning seat 5 , and the top of the protective plate 21 is configured as an inclined flow-guiding sliding surface.

[0028] Specifically, a waste trough 13 is provided on the outer seat 5031, so as to receive the waste chips generated when the forging is under pressure in the die seat 6, so that the waste chips are automatically discharged through the discharge channel, and a protective plate 21 is provided on the upper side of the positioning seat 5. On the one hand, it can protect the gear transmission components, and on the other hand, it is convenient for the waste chips falling on the protective plate 21 to automatically slide down along the guide surface, thereby ensuring the cleanliness of the working surface of the equipment and facilitating the cleaning and collection of the waste chips.

[0029] Example 4: Reference Figure 5 , Figure 7 and Fig. 9 A hydraulic press device suitable for forging various flange blanks. On the basis of Example 3, further, the die base 6 includes sub-seat bodies 601 evenly distributed on the circumference, each sub-seat body 601 is fixedly provided with a positioning rod 15 on the outer side, and an elastic telescopic plate 16 is fixedly provided on the placement seat 503. A positioning hole 161 matching the positioning rod 15 is opened at one end of the elastic telescopic plate 16 away from the placement seat 503.

[0030] Specifically, the staff will connect the positioning rod 15 on the lower side of the adapter mold base 6 with the positioning hole 161 on the elastic telescopic plate 16 according to the size of the flange to be processed, and place different mold bases 6 to facilitate rapid replacement of the mold base 6, so that a variety of different flanges can be processed.

[0031] Example 5: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 A hydraulic press device suitable for forging a variety of flange blanks. On the basis of Example 4, further, a lower conical surface is provided on the top of the movable seat 5032, and an upper conical surface is provided on the bottom of the die seat 6 to movably abut against the lower conical surface. A plurality of slide grooves 17 are evenly provided in a circumference in the outer seat 5031, and a wedge-shaped push block 171 is slidably connected in each slide groove 17, and the wedge-shaped push block 171 is movably abutted against the lower arc surface of the movable seat 5032, and a fixed block 501 is rotatably connected to A driven gear 18 meshing with the rack plate 901 is provided with a winding rod 181, and a third pull rope 182 and a fourth pull rope 183 are wound around the winding rod 181. The winding directions of the third pull rope 182 and the fourth pull rope 183 are opposite. The ends of the third pull rope 182 and the fourth pull rope 183 away from the winding rod 181 are connected to the wedge-shaped push block 171, and the third pull rope 182 and the fourth pull rope 183 are respectively connected to one side of the wedge-shaped push block 171.

[0032] Specifically, when the rack plate 901 slides back and forth on the fixed block 501, the rack plate 901 is meshed with the driven gear 18 at the same time, so that the driven gear 18 drives the winding rod 181 to rotate forward and reversely. When the pressure head 4 moves upward, the third pull rope 182 is wound up to pull the wedge-shaped push block 171, and the fourth pull rope 183 is released and no longer exerts force on the wedge-shaped push block 171, so that the wedge-shaped push block 171 slides to the side away from the movable seat 5032, and the wedge-shaped push block 171 no longer supports the movable seat 5032. The movable seat 5032 moves downward under the action of gravity, and the top of the movable seat 5032 no longer presses the lower side of the mold base 6. The various sub-seat bodies 601 of the mold base 6 are dispersed under the pull of the elastic telescopic plate 16; The blowing port on the connecting plate 401 blows the dispersed die base 6, so that the oxidized waste generated by the forging of the forging by the pressing head 4 is blown away and away from the internal groove of the die base 6, and the oxidized debris falls into the waste groove 13 or the gap between the protective plate 21 and the placement seat 503; When the ram 4 moves downward, the third pull rope 182 is released and the fourth pull rope 183 is reeled in and exerts force on the wedge-shaped push block 171, and the wedge-shaped push block 171 moves toward the side close to the movable seat 5032, and the wedge-shaped push block 171 pushes the bottom of the movable seat 5032 to move the movable seat 5032 upward, and the wedge-shaped push block 171 moves to the lower side of the movable seat 5032 and supports the movable seat 5032, providing stable support for the ram 4 during forging of the forging; By utilizing the upward and downward movement of the pressure head 4, the automatic separation and combination of the die base 6 is realized. Each time the pressure head 4 moves upward, the die base 6 is automatically separated, which is convenient for cooperating with the air jet to blow away the waste chips generated in the die base 6 during the forging of the forging. At this time, the forging is forged but has not yet abutted against the inner wall of the die base 6, thereby avoiding excessive waste chips from accumulating in the die base 6 and re-combining with the forgings that gradually fill the die base 6, reducing the processing time of subsequent flange forgings and improving the flange processing efficiency. The upward movement of the pressure head 4 disperses the die base 6, which is convenient for the automatic separation of the die base 6 and the forging, avoiding the forgings being tightly filled in the die base 6 after forming, resulting in the forgings being difficult to demold, improving the demolding efficiency of the forgings, and further improving the processing efficiency of the flange forgings.

[0033] Example 6: Reference Figure 1 , Figure 2 and Fig.11 A hydraulic press device suitable for forging various flange blanks. On the basis of Example 5, further, a recessed hole 19 is opened in the middle of the movable seat 5032, a baffle 191 is hinged in the recessed hole 19, a second hydraulic cylinder 192 movably connected to the baffle 191 is rotatably connected to the movable seat 5032 through a pin shaft, a third hydraulic cylinder 20 is fixed in the pressure head 4, and a piston rod of the third hydraulic cylinder 20 is connected to a punching head 2001.

[0034] Specifically, after the ram 4 reciprocates up and down to forge the forging and fills the forging in the die base 6 for forming, as the main bevel gear 121 meshes with the secondary bevel gear 703 for multiple cycles, when the ram 4 is about to abut against the die base 6, the main bevel gear 121 no longer meshes with the secondary bevel gear 703, and the placement seat 503 is reset under the elastic force of the first elastic telescopic rod 8, and the placement seat 503 is located directly below the ram 4. Then the ram 4 abuts against the top of the die base 6, and the second hydraulic cylinder 192 is controlled to operate, and the baffle 191 is flipped to open the concave hole 19 at the movable seat 5032, and then the third hydraulic cylinder 20 is controlled to operate, so that the third hydraulic cylinder 20 controls the punching head 2001 to move reciprocatingly up and down, and the punching head 2001 punches the forged flange forging to complete the preliminary processing of the flange forging, and the forming and punching steps are performed using the same die base 6, without the need to transfer the forging or replace the processing equipment, thereby improving the processing efficiency of the flange forging.

[0035] The present invention also discloses a forging method of a hydraulic press device suitable for forging a variety of flange blanks, comprising the following steps: S1: The staff inserts the positioning rod 15 on the lower side of the adapter die base 6 into the positioning hole 161 on the elastic expansion plate 16 according to the size of the flange to be processed, places the die base 6, and then places the forging in the die base 6; S2: Control the first hydraulic cylinder 3 to operate, and the piston rod of the first hydraulic cylinder 3 drives the ram 4 to move up and down, so that the ram 4 forges the forging in the die base 6; S3: When the connecting plate 401 moves upward, the rack plate 901 is pulled by the second pull rope 902. When the connecting plate 401 moves downward, the rack plate 901 moves back under the elastic force of the second elastic telescopic rod 10, so that the rack plate 901 moves back and forth on the fixed block 501. The rack plate 901 meshes with the one-way gear 11 to drive the pressure head 4 to move downward. When forging the forging, the one-way gear 11 drives the gear ring 12 to rotate, and the main bevel gear 1 on the gear ring 12 21 is intermittently meshed with the secondary bevel gear 703 on the rotating rod 7.
