[0015] A method for using a stainless steel flange continuous stamping device comprises the following steps: S1. Place the workpiece with the required flange on the work platform, pull the rack control arm out of the slot through the tooth arm, control the meshing length of the rack base and the folded rack with the input gear, start the drive cylinder, and drive the direct-acting frame to press down. The toggle pin on its surface is located at the top of the driven column and will follow the descent of the direct-acting frame to press it down, driving the connecting pin to press down, and at this time, the bottom position of the connecting pin will exceed the stamping die head, and the descent of the connecting pin will take precedence over the stamping die head. The connecting pin drives the vertical movable column to pull The vertical rack meshes with the conversion gear and drives it to rotate through direct motion, and then the conversion gear meshes with the horizontal rack to convert the rotation into direct motion again, converting the vertical direct motion of the vertical movable column into the horizontal direct motion of the horizontal movable column, pushing the clamping jaw housing to clamp the clamping jaw, at this time the horizontal movable column moves inward and drives the rack base and the multiple folding racks connected thereto to move linearly, and the meshing input gear rotates, at this time the active ratchet column and the driven ratchet column are in outwardly inclined surface contact, which will push the driven ratchet column upward and thus have no effect; S2. During the inward movement of the jaw housing, the driven gear meshes with the fixed rack and rotates toward the center of the work platform. Through the transmission effect of the inner connecting belt and the outer connecting belt on the outer pulley and the inner pulley on the two internal connecting shaft surfaces, the jaw housing rotates inward at the same time and drives the traction belt connected to the surface to rotate. At this time, the part of the traction belt exposed on the jaw housing has a downward transmission direction and contacts the workpiece to be clamped inside when the jaw housing moves inward, pressing the workpiece downward until the stamping die contacts the surface of the workpiece, and further pressing down to stamp out the surface flange; S3, the punching die and the connecting pin are both at the bottom after the punching is completed, while the driven column is at the top of the delay slot. At this time, the driving cylinder pulls the direct-acting frame to rise and retract, and the punching die and the delay slot rise. At this time, the driven column does not contact the bottom of the delay slot and will slide inside it until the bottom of the delay slot contacts the driven column, which will lift the driven column and the connecting pin upward, so that the rising of the connecting pin lags behind the punching die. The jaw housing will not be released until the punching die is completely separated from the workpiece; S4. When the direct-acting frame rises and is retracted, the horizontal movable column moves outward and drives the rack base and the multiple folding racks connected thereto to move in a straight line, and engages with the input gear to drive it to rotate. At this time, the active ratchet column contacts the inwardly inclined surface of the driven ratchet column, which will hook it and drive it to rotate, driving the rotating base to rotate on the fixed base, and the rotation angle is controlled by the folding rack, so that the flange holes can be punched around the flange surface, and the spacing of the flange holes can be controlled.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, through the cooperation of the stamping process mechanism and the clamp linkage mechanism, the driving cylinder drives the clamps in four directions to clamp the workpiece. The stamping process mechanism provides driving force and controls the entry and exit sequence of the clamp and the die head, so that the clamp always clamps the workpiece when the die head is stamping and ejecting. The clamp linkage mechanism uses gear racks to decompose the vertical movement of the driving cylinder into horizontal movements in four directions, and controls multiple clamps to clamp the workpiece.

[0017] In the present invention, through the setting of the clamping claw traction mechanism, during use, when the clamping claw shell moves inward to clamp, the internal traction belt will flip downward and contact the workpiece. Since the transmission direction is downward, the workpiece is pressed downward to prevent the workpiece from tilting during the clamping process.

[0018] In the present invention, through the setting of the intermittent rotation mechanism, during the opening and closing process of the jaw shell, the ratchet does not work when it is merged, and the workpiece on the surface is rotated when it is separated, so that the punching head can punch flange holes in a circle, and each rotation angle is controlled by the rack to achieve the effect of punching flange holes with different spacings.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 13The present invention provides a technical solution: a stainless steel flange continuous stamping device and a method for using the same, comprising a device base 1, a working platform 2 is fixedly connected to the top surface of the device base 1, a rack through slot 21 is provided on the outer surface of the working platform 2, a tooth arm through slot 211 is provided on the outer surface of the working platform 2, an outer support frame 3 is fixedly connected to the top surface of the working platform 2, an outer mounting column 31 is fixedly connected to the top surface of the working platform 2, a cylinder bracket 32 ​​is fixedly connected to the top surface of the outer mounting column 31, a stamping process mechanism 4 is arranged on the bottom surface of the cylinder bracket 32, a clamp linkage mechanism 5 is arranged on the top surface of the outer support frame 3, a clamp traction mechanism 6 is arranged at one end of the clamp linkage mechanism 5, an intermittent rotation mechanism 7 is arranged on the inner surface of the working platform 2, the device base 1, the working platform 2, the outer support frame 3 and the outer mounting column 31 are used to install various components, and the rack through slot 21 and the tooth arm through slot 211 provide entry and exit space for the intermittent rotation mechanism 7.

[0023] The stamping process mechanism 4 includes a driving cylinder 41, which is fixedly connected to the inner surface of the cylinder bracket 32, the output end of the driving cylinder 41 is fixedly connected to a direct-acting frame 42, the bottom surface of the direct-acting frame 42 is fixedly connected to a stamping die head 421, the outer surface of the direct-acting frame 42 is fixedly connected to an outer limit column 43, the outer surface of the direct-acting frame 42 is provided with a delay groove 44, the inner surface of the direct-acting frame 42 is slidably connected to a connecting pin 45, the outer surface of the connecting pin 45 is fixedly connected to a driven column 451, the outer surface of the direct-acting frame 42 is fixedly connected to a limit bracket 46, the inner surface of the limit bracket 46 is slidably connected to a toggle pin 461, one end of the toggle pin 461 is hingedly connected to a sliding card block 4611, and the sliding card The outer surface of the block 4611 is slidably connected with a slide mounting plate 462, and the inner surface of the slide mounting plate 462 is provided with a pin path groove 4621. Through the setting of the stamping process mechanism 4, during use, the driving cylinder 41 drives the direct-acting frame 42 to realize vertical movement, and the movement path is limited to prevent deviation through the connection with the mounting shell 51 through the outer limit column 43. During the descent of the direct-acting frame 42, the workpiece placed on the rotating base 72 is processed by the stamping die 421 at the bottom, and at the same time, the direct-acting frame 42 presses down the connecting pin 45, and drives the clamping claw shell 61 to move inward to clamp the workpiece through the clamp linkage mechanism 5. When the direct-acting frame 42 is at the bottom, the stamping die 421 and the connecting pin 45 are both at the bottom, and the driven column 45 1 is located at the top of the delay slot 44. At this time, the driving cylinder 41 pulls the direct-acting frame 42 to rise and retract, the stamping die 421 rises synchronously, and the delay slot 44 also rises. At this time, the driven column 451 does not contact the bottom of the delay slot 44 and will slide inside it until the bottom of the delay slot 44 contacts the driven column 451, and the driven column 451 and the connecting pin 45 are lifted up, so that the rise of the connecting pin 45 lags behind the stamping die 421. In this way, the clamping jaw housing 61 will not be released until the stamping die 421 is completely separated from the workpiece, so as to prevent the stamping die 421 from rising due to friction with the workpiece. During the rising process of the direct-acting frame 42, the surface limit bracket 46 and the toggle pin 461 will be driven to rise at the same time. The toggle pin 461 can only be moved when the limit bracket 4 6, since the toggle latch 461 is connected to the latch path slot 4621 through the sliding block 4611, the lateral movement of the toggle latch 461 during the rising process is pulled by the latch path slot 4621. When the direct-acting frame 42 drives the delay slot 44 to rise, the driven column 451 is first located at the top of the delay slot 44, and gradually approaches the bottom of the delay slot 44 as the delay slot 44 rises. At this time, the sliding block 4611 slides upward in the latch path slot 4621, but the latch path slot 4621 is vertical at this time, and the sliding block 4611 does not move at all. When the driven column 451 touches the bottom of the delay slot 44, the sliding block 4611 contacts the inclined part of the latch path slot 4621, and when the delay slot 44 pulls the driven column 451 to rise later,The sliding block 4611 will be pushed out by the latch path groove 4621, so that the toggle latch 461 gradually covers the surface of the driven column 451 until the direct-acting frame 42 reaches the top. When the direct-acting frame 42 is pressed down again, although the top of the delay groove 44 does not contact the driven column 451 at this time, the toggle latch 461 located at the top of the driven column 451 will follow the descent of the direct-acting frame 42 to press it down. The toggle latch 461 will gradually retract in the middle, but it will still partially contact the driven column 451 to press it down until it is completely out of contact. Moreover, since the driven column 451 is located at the bottom of the delay groove 44 at this time, the bottom position of the connecting latch 45 will exceed the punching die 421, so that the descending of the connecting latch 45 takes precedence over the punching die 421 when pressing down. In this way, the clamp housing 61 has already clamped the workpiece before the punching die 421 punches, so that the punching in and out always occurs when the workpiece is clamped.

[0024] The number of the outer limit posts 43 is four, and the four outer limit posts 43 are symmetrically distributed with the central axis of the direct-acting frame 42 as the axis of symmetry. The number of the delay slots 44 and the connecting pins 45 are both four, and the four delay slots 44 and the four connecting pins 45 are all distributed in a ring shape on the outer surface of the direct-acting frame 42. The driven post 451 is slidably connected to the inner surface of the delay slot 44. The number of the limit brackets 46 and the toggle pins 461 are both four, and the four limit brackets 46 and the four toggle pins 461 are all distributed in a ring shape on the outer surface of the direct-acting frame 42. The toggle pins 461 are slidably connected to the outer surface of the driven post 451. The moving card block 4611 is slidably connected to the inner surface of the pin path groove 4621. Each component on the direct-acting frame 42 is in four groups, which clamps the workpiece in four directions, disperses the force and increases the clamping effect. When rising, the opening and closing of the clamping jaws lags behind the die head. When descending, the opening and closing of the clamping jaws takes precedence over the die head through the toggle pin 461 and the pin path groove 4621. Since the toggle pin 461 is hingedly connected to the sliding card block 4611, it can adapt to the angle of the pin path groove 4621 when it is tilted, and is used to drive the toggle pin 461 to move horizontally by the vertical movement.

When the connecting pin 45 drives the vertical movable column 53 to pull the vertical rack 532 to move in the vertical direction, the vertical rack 532 engages with the conversion gear 52 to drive it to rotate through direct motion, and then the conversion gear 52 engages with the horizontal rack 542 to convert the rotation into direct motion again, and converts the vertical direct motion of the vertical movable column 53 into the horizontal direct motion of the horizontal movable column 54, pushing the clamp housing 61 to realize the opening and closing of the clamp.

The vertical racks 532 and horizontal racks 542 are both engaged with half of the conversion gears 52 to prevent mutual contact, and the other ends of the vertical racks 532 and horizontal racks 542 extend out from the mounting shell 51.

Through the setting of the clamping claw traction mechanism 6, during use, the clamping claw shell 61 is connected to the clamp linkage mechanism 5 Movement is achieved by pushing and pulling, and during the movement, the driven gear 66 meshes with the fixed rack 661 to generate rotation. When the clamp housing 61 moves inward, the rotation direction of the driven gear 66 is toward the center of the working platform 2, and the connected shaft 62 is driven to rotate through the driven gear 66.

At this time, the part of the traction belt 65 exposed on the clamp housing 61 has a downward transmission direction, and contacts with the workpiece to be clamped inside when the clamp housing 61 moves inward, pressing the workpiece downward to prevent the workpiece from warping during the clamping process.

The outer connecting belt 631 is sleeved between the outer pulleys 63, and the inner connecting belt 641 is sleeved between the inner pulleys 64. The fixed rack 661 is slidably connected to the fixed tooth through the inner surface of the groove 543, and the traction belt The two ends of 65 are fixedly connected to the outer connecting belt 631 and the inner connecting belt 641 respectively. There are four fixed racks 661, and the four fixed racks 661 are symmetrically distributed with the central axis of the working platform 2 as the symmetry axis. The four clamping jaw housings 61 disperse the force to increase the clamping effect. The two connecting shafts 62 inside the clamping jaw housing 61 are simultaneously rotated inward through the belt transmission. Since the size of the outer pulley 63 is larger than that of the inner pulley 64, the sizes of the two ends of the traction belt 65 are inconsistent, and they will gradually retract inward to adapt to the arc surface of the clamping jaw housing 61, and the outer pulley 63 and the inner pulley 64 can be on the same axis. The fixed rack 661 passes through the fixed tooth through slot 543 without affecting the linear motion of the horizontal movable column 54.

Through the setting of the intermittent rotation mechanism 7, during use, the horizontal movable column 54 on the clamp linkage mechanism 5 connected to the outer mounting column 31 is connected to the rack base 74 and slides in the rack through the groove 21. When the horizontal movable column 54 moves horizontally, it will drive the rack base 74 The rack base 74 and the folding rack 741 connected thereto move in a straight line. Both the rack base 74 and the folding rack 741 are meshed with the input gear 73. By folding the folding rack 741 to control the meshing length with the input gear 73, the rotation angle of the input gear 73 is achieved during each movement. The outermost folding rack 741 is connected to a rack control arm 75. When the rack control arm 75 is pulled out of the tooth arm through slot 211, the pressing wedge block 77 on the surface will be pressed down and reset under the action of the wedge block return spring 772 to clamp it on the outside of the tooth arm through slot 211 to maintain the current extended state.

After the rack limit block 76 is pushed out, it will also be tightly attached to the rack base 74 and the folding rack under the action of the limit return spring 763. The folding rack 741 can only rotate in one direction, and the direction is blocked by the L-shaped rack stop block 76, so that the folding rack 741 maintains a vertical state after folding, thereby controlling the meshing length with the input gear 73. When the jaw housing 61 is pushed inward, the rack base 74 and the folding rack 741 push the input gear 73 to rotate forward, but at this time, the active ratchet column 723 on the top of the input gear 73 is in contact with the driven ratchet column 721 with an outwardly inclined surface, which will push the driven ratchet column 721 upward and thus have no effect. When the jaw housing 61 is pulled out, the stamping die 421 has been pulled out, and the input gear 73 reverses. At this time, the active ratchet column 723 is in contact with the inwardly inclined surface of the driven ratchet column 721, which will hook it and drive it to rotate.The rotation limiting column 722 outside the driven ratchet column 721 does not affect the movement of the driven ratchet column 721 on the rotating base 72, but it will limit the rotation. When the driven ratchet column 721 rotates, it will force the rotating base 72 to rotate on the fixed base 71, so that the workpiece on the surface rotates a certain angle when the clamping jaws are separated, and the rotation angle is controlled by the folding rack 741, so that the flange holes can be punched around the flange surface, and the spacing of the flange holes can be controlled.

During the descent, the workpiece placed on the rotating base 72 is processed by the punching die 421 at the bottom. At the same time, the direct-acting frame 42 presses down the connecting pin 45, driving the vertical movable column 53 to pull the vertical rack 532. By using the gear rack, the vertical movement of the driving cylinder 41 is decomposed into horizontal movements in four directions, and the multiple clamping claw traction mechanisms 6 are controlled to clamp the workpiece; In this embodiment, Figure 4 , Figure 6 , Figure 7 As shown in FIG. 4 , the toggle latch 461, the delay slot 44 and the driven column 451 are in different states when they cooperate with each other. Figure 4 When the direct-acting frame 42 is at the bottom, the toggle latch 461 does not contact the driven column 451, and the vertical upward lateral position remains unchanged. The driven column 451 does not contact the bottom of the delay slot 44 and will not be lifted by the delay slot 44. The delay slot 44 and the toggle latch 461 move upward with the direct-acting frame 42 until Figure 6 In this state, the driven column 451 contacts the delay slot 44 and can be lifted upward, and the toggle latch 461 is about to move to the inclined position. Continuing to move will cause the toggle latch 461 to gradually extend when the driven column 451 is lifted, until it becomes Figure 7 When the direct-acting frame 42 descends, even if the driven column 451 is not pressed down by the top of the delay slot 44, it will be pressed down by the toggle pin 461, and at this time, the driven column 451 is located at the bottom of the delay slot 44, which is lower than the position of the punching die 421; In this embodiment, Figure 5 As shown, a fixed tooth passing groove 543 is provided on the horizontal movable column 54 for the fixed rack 661 to pass through; In this embodiment, Figure 8 As shown, the vertical rack 532 is meshed with the conversion gear 52 to drive it to rotate through direct motion, and then the conversion gear 52 is meshed with the horizontal rack 542 to convert the rotation into direct motion again, converting the vertical direct motion of the vertical movable column 53 into the horizontal direct motion of the horizontal movable column 54; In this embodiment, Fig. 9 As shown, since the size of the outer pulley 63 is larger than that of the inner pulley 64, the sizes of the two ends of the traction belt 65 are inconsistent, and it will gradually retract inward to adapt to the arc surface of the clamping jaw housing 61, and the outer pulley 63 and the inner pulley 64 can be on the same axis, so that the traction belt 65 can contact and press down the workpiece to be clamped inside the clamping jaw housing 61 when it moves inward; In this embodiment, Fig.10As shown, when the horizontal movable column 54 moves horizontally, it drives the rack base 74 and the multiple folding racks 741 connected thereto to move linearly, and the rack base 74 and the folding racks 741 are both engaged with the input gear 73.

[0032] In this embodiment, Fig.12 , Fig.13 As shown, the rack control arm 75 is pulled out from the tooth arm through the slot 211 to control the meshing length of the rack base 74 and the folding rack 741 with the input gear 73. Since the folding rack 741 can only rotate in one direction and the reverse direction is blocked by the L-shaped rack limit block 76, the folding rack 741 maintains a vertical state after folding.

[0033] A method for using a stainless steel flange continuous stamping device comprises the following steps: S1. Place the workpiece with the required flange on the work platform 2. Pull the rack control arm 75 out of the tooth arm slot 211 to control the meshing length of the rack base 74 and the folded rack 741 with the input gear 73. Start the drive cylinder 41. The drive cylinder 41 drives the direct-acting frame 42 to press down. The toggle pin 461 on its surface is located at the top of the driven column 451 and will follow the descent of the direct-acting frame 42 to press it down, driving the connecting pin 45 to press down. At this time, the bottom position of the connecting pin 45 will exceed the stamping die 421. The descent of the connecting pin 45 takes precedence over the stamping die 421. The connecting pin 45 drives the vertical movable column 461 to press down. 53 pulls the vertical rack 532 to mesh with the conversion gear 52 and drives it to rotate through direct motion, and then the conversion gear 52 meshes with the horizontal rack 542 to convert the rotation into direct motion again, converting the vertical direct motion of the vertical movable column 53 into the horizontal direct motion of the horizontal movable column 54, pushing the clamping jaw housing 61 to achieve the clamping of the clamping jaw. At this time, the horizontal movable column 54 moves inward and drives the rack base 74 and the multiple folding racks 741 connected thereto to move linearly, meshing the input gear 73 to rotate, at this time, the active ratchet column 723 and the driven ratchet column 721 are in outwardly inclined surface contact, which will push the driven ratchet column 721 upward and thus have no effect; S2, during the process of the jaw housing 61 moving inward, the driven gear 66 meshes with the fixed rack 661 and rotates toward the center of the work platform 2, and realizes simultaneous inward rotation through the outer pulley 63 on the surface of the two internal connecting shafts 62 and the inner connecting belt 641 and the outer connecting belt 631 on the inner pulley 64, and drives the traction belt 65 connected to the surface to rotate. At this time, the part of the traction belt 65 exposed on the jaw housing 61 is driven downward, and contacts with the workpiece to be clamped inside when the jaw housing 61 moves inward, pressing the workpiece downward until the stamping die 421 contacts the surface of the workpiece, and further pressing down to stamp out the surface flange; S3, the punching die 421 and the connecting pin 45 are both at the bottom after the punching is completed, and the driven column 451 is at the top of the delay slot 44. At this time, the driving cylinder 41 pulls the direct-acting frame 42 to rise and retract, and the punching die 421 and the delay slot 44 rise. At this time, the driven column 451 does not contact the bottom of the delay slot 44 and will slide inside it until the bottom of the delay slot 44 contacts the driven column 451, and then the driven column 451 and the connecting pin 45 are lifted up, so that the rising of the connecting pin 45 lags behind the punching die 421, and the clamp housing 61 will not be released until the punching die 421 is completely separated from the workpiece; S4. When the direct-acting frame 42 rises and is retracted, the horizontal movable column 54 moves outward and drives the rack base 74 and the multiple folding racks 741 connected thereto to move in a straight line, and engages with the input gear 73 to drive it to rotate. At this time, the active ratchet column 723 contacts the inwardly inclined surface of the driven ratchet column 721, hooks it and drives it to rotate, drives the rotating base 72 to rotate on the fixed base 71, and the rotation angle is controlled by the folding rack 741, so that the flange holes can be punched around the flange surface, and the spacing of the flange holes can be controlled.
