[0012] Preferably, the method for using the stainless steel flange continuous forming device comprises the following steps: S1: Place the stainless steel flange in the placement slot on the top of the forming processing table, clamp the stainless steel flange to be processed by the three-jaw chuck, and move the punch rod downward under the drive of the oil cylinder, and the punch rod drives the mounting frame downward, and the outer support tube moves toward the opening of the flange. Driven by the pressure spring, the connecting rod moves downward synchronously, and then the punch plate is punched toward the opening of the flange; S2: The bottom of the punching plate contacts the placement groove, and the connecting rod is driven by the punching rod to shrink in the outer support tube. The connecting tube arranged on the outer wall of the connecting rod is relatively displaced with the outer support tube, and the connecting tube moves toward the direction of the outer support tube. Under the restriction of the upper limit groove of the support plate, the movement of the connecting tube drives the fixed frame to squeeze the two hinged connecting rods. At this time, the two hinged connecting rods will expand toward the outside of the connecting tube, and the two hinged connecting rods will drive the expansion frame to expand and move toward the flange opening on the support plate. The friction protrusion on the outer wall of the expansion frame will be tightly attached to the opening of the flange. After being unfolded, the expansion frame can make the friction protrusion contact with the opening of the flange. S3: When the connecting rod moves upward, the carrier frame will move upward on the outer support tube, and the inclined surface on the carrier frame will squeeze the clamping block to make the clamping rod contract under the drive of the connecting spring, and the clamping rod will dock with the clamping groove. Since the clamping rod is slidably arranged on the outer support tube, when the clamping rod is clamped with the clamping groove on the carrier frame, the outer support tube and the connecting rod will be limited. At this time, the oil cylinder drives the stamping rod to move upward to reset the outer support tube, and the expansion member is in an expanded state; S4: After the flange is stamped, when the oil cylinder drives the stamping rod to move up and reset, the protrusion on the stamping rod will move from the longitudinal slide to the oblique slide. At this time, the oblique slide will drive the rotating outer cylinder to rotate under the restriction of the protrusion. The rotating outer cylinder rotates and drives the rotating ring set in the limit sleeve to rotate. The rotating ring is tightly attached to the clutch clamping plates on the two clamping rods, and then the outer support cylinder can be driven to rotate through the two clamping rods. When the outer support cylinder rotates, it can synchronously drive the support plate to rotate the connecting rod, and the support plate will rotate the expansion piece in the expanded state, and the expansion piece can be rotationally polished around the inner wall of the flange opening; S5: When the clamping rod moves into the clamping groove driven by the inclined surface on the carrier, the clamping rod extends toward the clamping groove driven by the connecting spring, and the clamping block contacts the block on the barrier frame when extending toward the clamping groove, causing the barrier frame to deflect in the accommodating cavity. After the barrier frame deflects, the block abuts against the annular groove of the clamping block, and the barrier frame squeezes the push rod when deflecting, and the compression spring on the push rod enables the barrier frame to effectively limit the clamping block in the clamping groove; S6: When the punch rod drives the outer support tube to continuously move upward, the outer support tube will move toward the inner top of the limit sleeve. At this time, the docking interface on the carrier frame is docked with the limit column, and the conical end of the limit column contacts the wedge-shaped end of the unlocking block, so that the unlocking block moves toward the direction of the push rod. Since the spacer frame is arranged between the unlocking block and the push rod, the spacer frame can be squeezed when the unlocking block moves, so that the spacer frame continues to deflect in the accommodating cavity. At this time, the block on the spacer frame will be separated from the annular groove on the clamping block. After the clamping block is separated from the block, the connecting rod will be reset driven by the pressure spring. S7: The driving disk is driven by the servo motor to rotate continuously. When the driving disk rotates continuously, the intermittent frame arranged on the driving disk will contact the intermittent turntable, so that the intermittent turntable can rotate intermittently. The intermittent turntable drives the rotating rod to rotate intermittently so that the three-jaw chuck can rotate intermittently. After a hole is opened at one place of the flange, the intermittent rotation of the rotating rod can drive the three-jaw chuck to rotate intermittently to open a hole at another place of the flange.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, after the flange is punched with a hole by the punching disk, the four expansion members can be unfolded under the drive of the expansion member. After unfolding, the expansion frame can make the friction protrusion contact with the opening of the flange, so that when the oil cylinder drives the punching rod to move up and reset, the opening of the flange is polished under the drive of the expansion member. By polishing the punched hole of the flange, the burrs formed after the flange is punched can be removed, which is convenient for the subsequent further processing of the flange.

[0014] In the present invention, when the clamping rod is clamped with the clamping groove on the carrier frame, the outer support tube and the connecting rod are limited. At this time, the oil cylinder drives the stamping rod to move upward to reset the outer support tube. The expansion piece is in an expanded state, and then the expansion piece in the expanded state can effectively contact the opening of the flange when moving upward, thereby grinding the opening of the flange.

[0015] In the present invention, when the outer support tube rotates, it can synchronously drive the support plate to rotate the connecting rod, and the support plate will rotate the expansion piece in the expanded state, so that the expansion piece is tightly attached to the opening of the flange, and the expansion piece in rotation can be rotationally polished around the inner wall of the flange opening, thereby comprehensively polishing the opening of the flange. The burrs and sharp edges generated by the opening can be removed by polishing, so that the surface of the flange opening is smooth, thereby improving safety and assembly quality. The flange is sealed with a sealing gasket, and the smooth opening surface can better fit the gasket, thereby improving the sealing performance and preventing medium leakage.

[0016] In the present invention, when the clamping rod and the clamping groove are docked, the clamping rod can be effectively limited and fixed under the restriction of the block on the partition frame, thereby preventing the punching rod from driving the connecting rod to move upward, and the pressure spring between the connecting rod and the outer support tube from separating, thereby preventing the expansion piece from shrinking during the upward movement and being unable to effectively contact the flange opening.

[0017] In the present invention, when the unlocking block moves, it can squeeze the partition frame, so that the partition frame continues to deflect in the accommodating cavity. At this time, the block on the partition frame will be separated from the annular groove on the clamping block. After the clamping block is separated from the block, the connecting rod will be reset under the drive of the pressure spring, thereby separating the clamping rod from the clamping groove on the carrier frame, and separating the outer support tube from the connecting rod. After the outer support tube is separated from the connecting rod, the expansion piece will shrink to its initial state, thereby facilitating the subsequent grinding of the opening when another hole is opened at another location of the flange.

[0018] In the present invention, the intermittent turntable drives the rotating rod to rotate intermittently so that the three-jaw chuck is intermittently rotated. After a hole is opened at one point of the flange, the intermittent rotation of the rotating rod can drive the three-jaw chuck to rotate the flange intermittently to perform a hole opening process at another point of the flange.

The clamping block 44 can be effectively limited in the clamping groove 42. Through this arrangement, when the clamping rod 43 and the clamping groove 42 are docked, the clamping rod 43 can be effectively limited and fixed under the restriction of the stopper 66 on the barrier frame 65, so as to avoid that when the punching rod 15 drives the connecting rod 22 to move upward, the connecting rod 22 and the outer support tube 21 are separated under the drive of the pressure spring 26 between the connecting rod 22 and the outer support tube 21, so as to avoid that the expansion member 3 set in the upward movement process shrinks and cannot effectively contact with the flange opening; When the punch rod 15 drives the outer support tube 21 to continue to move upward, the outer support tube 21 will move toward the inner top of the limiting sleeve 52. At this time, the docking port 68 on the carrier 41 is docked with the limiting column 67. The limiting column 67 is provided with a conical end that contacts the wedge-shaped end of the unlocking block 64, thereby causing the unlocking block 64 to move toward the direction of the push rod 62. Since the spacer frame 65 is provided between the unlocking block 64 and the push rod 62, the spacer frame 65 can be squeezed when the unlocking block 64 moves, so that the spacer frame 65 continues to deflect in the accommodating cavity 61. At this time, the stopper 66 on the partition frame 65 will be separated from the annular groove on the clamping block 44. After the clamping block 44 is separated from the stopper 66, the connecting rod 22 will be reset under the drive of the pressure spring 26, so that the clamping rod 43 is separated from the clamping groove 42 on the carrier frame 41, and the outer support tube 21 is separated from the connecting rod 22. After the outer support tube 21 is separated from the connecting rod 22, the expansion member 3 will shrink to its initial state, thereby facilitating the subsequent grinding of the opening when another hole is opened at another location of the flange.

[0028] In this embodiment, an intermittent rotating member 7 is further provided at the bottom of the molding processing table 1, and the intermittent rotating member 7 includes a servo motor 71 fixedly connected to the bottom of the molding processing table 1, and the main shaft of the servo motor 71 is connected to a driving disk 72, and an intermittent frame 73 is provided on the driving disk 72. A rotating rod 74 is rotatably provided in the placement groove 12, and an intermittent rotating disk 75 is fixedly connected to the bottom of the rotating rod 74. The intermittent rotating disk 75 is matched with the intermittent frame 73 in transmission, and the top of the rotating rod 74 is located in the placement groove 12, and the top of the rotating rod 74 is fixedly connected to the three-jaw chuck 13; The driving disk 72 is driven by the servo motor 71 to rotate continuously. When the driving disk 72 rotates continuously, the intermittent frame 73 arranged on the driving disk 72 will contact the intermittent turntable 75, so that the intermittent turntable 75 can rotate intermittently. The intermittent turntable 75 drives the rotating rod 74 to rotate intermittently to make the three-jaw chuck 13 rotate intermittently. After a hole is opened at one place of the flange, the intermittent rotation of the rotating rod 74 can drive the three-jaw chuck 13 to rotate intermittently to open a hole at another place of the flange.

[0029] The use method and advantages of the present invention: The use method of the stainless steel flange continuous forming device, the working process is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 As shown: S1: Place the stainless steel flange in the placement slot 12 on the top of the forming processing table 1, clamp the stainless steel flange to be processed by the three-jaw chuck 13, drive the punch rod 15 downward under the drive of the oil cylinder 14, and the punch rod 15 drives the mounting frame 16 downward, and the outer support cylinder 21 moves toward the opening of the flange, and the connecting rod 22 is synchronously moved downward under the drive of the pressure spring 26, so that the punching plate 24 punches toward the opening of the flange; S2: The bottom of the punching plate 24 contacts the placement groove 12, and the connecting rod 22 is contracted in the outer support tube 21 under the drive of the punching rod 15, and the connecting tube 23 arranged on the outer wall of the connecting rod 22 is relatively displaced with the outer support tube 21, and the connecting tube 23 moves toward the direction of the outer support tube 21. Under the restriction of the upper limit groove 36 of the support plate 25, the connecting tube 23 moves and drives the fixing frame 31 to squeeze the two hinged connecting rods 32. At this time, the two hinged connecting rods 32 will expand toward the outside of the connecting tube 23, and the two hinged connecting rods 32 will drive the expansion frame 33 to expand and move toward the flange opening on the support plate 25, and the friction protrusion 34 on the outer wall of the expansion frame 33 will be tightly attached to the opening of the flange. After unfolding, the expansion frame 33 can make the friction protrusion 34 contact with the opening of the flange; S3: When the connecting rod 22 moves upward, the carrier 41 will move upward on the outer support tube 21, and the inclined surface 46 on the carrier 41 will squeeze the clamping block 44 to make the clamping rod 43 shrink under the drive of the connecting spring 45, and the clamping rod 43 will dock with the clamping groove 42. Since the clamping rod 43 is slidably arranged on the outer support tube 21, when the clamping rod 43 is clamped with the clamping groove 42 on the carrier 41, the outer support tube 21 and the connecting rod 22 are limited. At this time, the oil cylinder 14 drives the stamping rod 15 to move upward to make the outer support tube 21 move upward and reset, and the expansion member 3 is in an expanded state; S4: After the flange is stamped, when the oil cylinder 14 drives the stamping rod 15 to move up and reset, the protrusion 55 on the stamping rod 15 will move from the longitudinal slide 562 to the oblique slide 561. At this time, the oblique slide 561 will drive the rotating outer cylinder 51 to rotate under the restriction of the protrusion 55. The rotating outer cylinder 51 rotates and drives the rotating ring 53 that is clamped in the limiting sleeve 52 to rotate. The rotating ring 53 is tightly attached to the clutch clamping plates 54 on the two clamping rods 43, and then the outer support cylinder 21 can be driven to rotate through the two clamping rods 43. When the outer support cylinder 21 rotates, it can synchronously drive the support plate 25 to rotate the connecting rod 22. The support plate 25 will rotate the expansion member 3 in the expanded state, and the expansion member 3 can be rotationally polished around the inner wall of the flange opening. S5: When the clamping rod 43 moves into the clamping groove 42 driven by the inclined surface 46 on the carrier 41, the clamping rod 43 extends toward the clamping groove 42 driven by the connecting spring 45, and the clamping block 44 extends toward the clamping groove 42 and contacts with the stopper 66 on the barrier frame 65, causing the barrier frame 65 to deflect in the accommodating cavity 61. After the barrier frame 65 deflects, the stopper 66 abuts against the annular groove of the clamping block 44, and the barrier frame 65 squeezes the push rod 62 when deflecting, and the compression spring 63 on the push rod 62 enables the barrier frame 65 to effectively limit the clamping block 44 in the clamping groove 42; S6: When the punch rod 15 drives the outer support tube 21 to continuously move upward, the outer support tube 21 will move toward the inner top of the limiting sleeve 52. At this time, the docking port 68 on the carrier 41 is docked with the limiting column 67. The limiting column 67 is provided with a conical end that contacts the wedge-shaped end of the unlocking block 64, thereby causing the unlocking block 64 to move toward the direction of the push rod 62. Since the spacer frame 65 is provided between the unlocking block 64 and the push rod 62, the spacer frame 65 can be squeezed when the unlocking block 64 moves, so that the spacer frame 65 continues to deflect in the accommodating chamber 61. At this time, the stopper 66 on the spacer frame 65 will be separated from the annular groove on the clamping block 44. After the clamping block 44 is separated from the stopper 66, the connecting rod 22 will be reset under the drive of the pressure spring 26. S7: The driving disk 72 is driven by the servo motor 71 to rotate continuously. When the driving disk 72 rotates continuously, the intermittent frame 73 arranged on the driving disk 72 will contact the intermittent turntable 75, so that the intermittent turntable 75 can rotate intermittently. The intermittent turntable 75 drives the rotating rod 74 to rotate intermittently to make the three-jaw chuck 13 rotate intermittently. After a hole is opened at one place of the flange, the intermittent rotation of the rotating rod 74 can drive the three-jaw chuck 13 to rotate intermittently to open a hole at another place of the flange.

A method for using a stainless steel flange continuous forming device, using the stainless steel flange continuous forming device as claimed in any one of claims 1 to 8, characterized in that: The steps include: S1: The stainless steel flange is placed in the placement groove (12) on the top of the forming processing table (1), and the stainless steel flange to be processed is clamped and limited by the three-jaw chuck (13). The punching rod (15) is driven by the oil cylinder (14) to move downward, and the punching rod (15) drives the mounting frame (16) to move downward, and the outer support tube (21) moves toward the opening of the flange. The connecting rod (22) is synchronously moved downward under the drive of the pressure spring (26), and then the punching plate (24) is punched toward the opening of the flange; S2: The bottom of the punching plate (24) contacts the placement groove (12), and the connecting rod (22) is contracted in the outer support tube (21) under the drive of the punching rod (15). The connecting tube (23) arranged on the outer wall of the connecting rod (22) is displaced relative to the outer support tube (21), and the connecting tube (23) moves in the direction of the outer support tube (21). Under the restriction of the upper limit groove (36) of the support plate (25), the connecting tube (23) moves. The fixed frame (31) is driven to squeeze the two hinged connecting rods (32), and the two hinged connecting rods (32) will expand toward the outside of the connecting tube (23). The two hinged connecting rods (32) will drive the expansion frame (33) to expand and move toward the flange opening on the support plate (25), and the friction protrusion (34) on the outer wall of the expansion frame (33) will be in close contact with the flange opening. After the expansion, the expansion frame (33) can make the friction protrusion (34) contact with the flange opening. S3: When the connecting rod (22) moves upward, the carrier (41) moves upward on the outer support tube (21), and the inclined surface (46) on the carrier (41) squeezes the clamping block (44) to make the clamping rod (43) shrink under the drive of the connecting spring (45), and the clamping rod (43) docks with the clamping groove (42). Since the clamping rod (43) is slidably arranged on the outer support tube (21), when the clamping rod (43) is clamped with the clamping groove (42) on the carrier (41), the outer support tube (21) and the connecting rod (22) are limited. At this time, the oil cylinder (14) drives the punching rod (15) to move upward to make the outer support tube (21) move upward and reset, and the expansion member (3) is in an expanded state; S4: After the flange is stamped, the oil cylinder (14) drives the stamping rod (15) to move upward and reset, and the protrusion (55) on the stamping rod (15) moves from the longitudinal slideway (562) to the inclined slideway (561). At this time, the inclined slideway (561) drives the rotating outer cylinder (51) to rotate under the restriction of the protrusion (55). The rotating outer cylinder (51) rotates and drives the rotating ring (53) that is clamped in the limiting sleeve (52) to rotate. The ring (53) is in close contact with the clutch clamping plates (54) on the two clamping rods (43), and can drive the outer support tube (21) to rotate through the two clamping rods (43). When the outer support tube (21) rotates, it can synchronously drive the support plate (25) to rotate the connecting rod (22), and the support plate (25) can rotate the expansion member (3) in the expanded state, and the expansion member (3) can be subjected to rotational grinding treatment around the inner wall of the flange opening; S5: When the clamping rod (43) moves into the clamping groove (42) driven by the inclined surface (46) on the carrier frame (41), the clamping rod (43) extends toward the clamping groove (42) driven by the connecting spring (45), and the clamping block (44) contacts the stopper (66) on the barrier frame (65) when extending toward the clamping groove (42), causing the barrier frame (65) to deflect in the accommodating cavity (61). After the barrier frame (65) deflects, the stopper (66) abuts against the annular groove of the clamping block (44), and the barrier frame (65) presses the push rod (62) when deflecting, and the compression spring (63) on the push rod (62) enables the barrier frame (65) to effectively limit the clamping block (44) in the clamping groove (42); S6: When the punch rod (15) drives the outer support tube (21) to continuously move upward, the outer support tube (21) will move toward the inner top of the limiting sleeve (52), and at this time, the docking port (68) on the carrier (41) and the limiting column (67) are docked, and the limiting column (67) is provided with a conical end that contacts the wedge-shaped end of the unlocking block (64), thereby causing the unlocking block (64) to move toward the direction of the push rod (62). Since the spacer frame (65) is provided between the unlocking block (64) and the push rod (62), when the unlocking block (64) moves, it can squeeze the spacer frame (65), so that the spacer frame (65) continues to deflect in the accommodating chamber (61), and at this time, the stopper (66) on the spacer frame (65) will separate from the annular groove on the clamping block (44). After the clamping block (44) and the stopper (66) are separated, the connecting rod (22) will be reset under the drive of the pressure spring (26); S7: The driving disk (72) is driven by the servo motor (71) to continuously rotate. When the driving disk (72) continuously rotates, the intermittent frame (73) disposed on the driving disk (72) contacts the intermittent turntable (75), thereby enabling the intermittent turntable (75) to rotate intermittently. The intermittent turntable (75) drives the rotating rod (74) to rotate intermittently, thereby enabling the three-jaw chuck (13) to rotate intermittently. After a hole is drilled at one of the locations of the flange, the intermittent rotation of the rotating rod (74) can drive the three-jaw chuck (13) to rotate intermittently, thereby drilling a hole at another location of the flange.
