[0030] like Figures 1-10 The present invention provides a double-station corrugated pipe flattening wave shaping device, including a frame 1, a working platform 2 arranged on the frame 1, and a lifting seat 3 lifted and lowered on the frame 1, the working platform 2 is provided with a first mold assembly 4, and the lifting seat 3 is provided with a second mold assembly 5 with the same structure as the first mold assembly 4 and oppositely arranged; the first mold assembly 4 includes a mold mounting plate 41 installed on the working platform 2, a first slider 42 and a second slider 43 relatively movable on the mold mounting plate 41, the first slider 42 is provided with a first mold piece 44 on the side close to the second mold assembly 5, and the second slider 43 is provided with a second mold piece 45 opposite to the first mold piece 44 on the side close to the second mold assembly 5, and the opposite surfaces of the first mold piece 44 and the second mold piece 45 are provided with a molding groove 46, so that when the corrugated pipe 6 is processed, the first mold piece 44 and the second mold piece 45 clamp the outer periphery of the corrugated pipe 6 through the molding groove 46.

[0031] At least two groups of first mold assemblies 4 and second mold assemblies 5 are respectively installed on the working platform 2 and the lifting seat 3, so that the frame 1 has at least two flattening and shaping stations, and then the mold mounting plate 41 is fixed, and the structures in the first mold assembly 4 and the second mold assembly 5 are ensured to be arranged relative to each other. At this time, the corrugated tube 6 to be flattened and shaped can be placed in the molding groove 46 in the first mold assembly 4, and the lifting seat 3 drives the second mold assembly 5 to descend and makes the two ends of the corrugated tube 6 respectively pressed and positioned by the first mold assembly 4 and the second mold assembly 5, and then the first slider 42 and the second slider 43 in the two mold assemblies move close to each other synchronously, so that the first mold piece 44 and the second mold piece 45 are driven by the slider to clamp the corrugated tube 6 circumferentially, that is, the outer periphery of the corrugated tube 6 is clamped and positioned by the molding groove 46. At this time, the lifting seat 3 is lowered for the second time, and the corrugated tube 6 can be flattened and shaped. No manual operation is required during the overall flattening and shaping process, which can greatly improve the efficiency of the processing of the corrugated tube 6.

[0032] Specifically, the first slider 42 and the second slider 43 can move closer to or away from each other to facilitate the clamping or loosening operation of the bellows 6; the groove 46 structure at the first mold piece 44 and the second mold piece 45 matches the outer peripheral shape of the bellows 6 to be processed. When changing the type of bellows 6 to be processed, the style of the first mold piece 44 and the second mold piece 45 can be replaced to quickly adapt to different bellows 6 processing requirements to ensure the adaptability of this solution.

[0033] In one embodiment of the present scheme, the groove 46 has a semicircular opening structure, so that when the first mold piece 44 and the second mold piece 45 are close to each other to clamp the bellows 6, the two grooves 46 are spliced ​​to form a complete circle to adapt to the circular structure of the outer periphery of the bellows 6.

[0034] Preferably, the mold mounting plate 41 is connected to a first driving member 47 for driving the first slider 42 and the second slider 43, the first slider 42 and the second slider 43 are movably mounted on the first driving member 47, and the first driving member 47 in the first mold assembly 4 has a shaping lower mold 48 on the side, a guide rod 49 is provided at the shaping lower mold 48, and the bellows 6 is sleeved on the outer periphery of the guide rod 49, and the first driving member 47 in the second mold assembly 5 has a shaping upper mold 51 on the side, and a guide hole 52 corresponding to the guide rod 49 is opened at the shaping upper mold 51, and the guide rod 49 and the guide hole 52 are both located between the first mold piece 44 and the second mold piece 45.

[0035] Specifically, the clamping or loosening action of the first slider 42 and the second slider 43 is controlled by the first driving member 47. When the bellows 6 is initially placed, the bellows 6 is sleeved onto the guide rod 49, so that the guide rod 49 positions the bellows 6 axially, and the clamping of the matching groove 46 can position the bellows 6 circumferentially to ensure the stability of the bellows 6 during processing and the accuracy of the processing size. At the same time, when the bellows 6 is flattened, a cylindrical limiting space is formed by the groove 46 in the first mold assembly 4 and the second mold assembly 5, so that when the lifting seat 3 drives the second mold assembly 5 to perform a second downward pressure, the flattening outer diameter of the bellows 6 can be limited by the limiting space to ensure that the outer diameter of the bellows 6 after flattening meets the processing requirements.

[0036] It is worth mentioning that since the shaping upper mold 51 in the second mold assembly 5 has a guide hole 52 corresponding to the guide rod 49, when the second mold assembly 5 is pressed down, the two ends of the bellows 6 respectively press against the end faces of the shaping lower mold 48 and the shaping upper mold 51, and the purpose of flattening the bellows 6 is achieved by facing the two ends. At this time, the end of the guide rod 49 is inserted into the guide hole 52 to ensure that there is enough processing stroke between the two end faces to flatten the bellows 6.

[0037] In one embodiment of this solution, the first driving member 47 may adopt a cylinder structure, and the first slider 42 and the second slider 43 are sliders driven by the cylinder to ensure the circumferential positioning effect of the bellows 6.

[0038] Preferably, a first mold mounting plate 410 is connected between the first slider 42 and the first mold 44, a second mold mounting plate 411 is connected between the second slider 43 and the second mold 45, and there is a gap between the first mold 44 and the first mold mounting plate 410, and between the second mold 45 and the second mold mounting plate 411.

[0039] Specifically, through the setting of the first mold mounting plate 410 and the second mold mounting plate 411, the slider can drive the corresponding mold to clamp or loosen, and due to the gap setting between the mold and the mold mounting plate, the interface corrugations 61 at both ends of the bellows 6 can be snapped into the gap, and then the interface corrugations 61 are specially flattened to meet the different processing requirements of the middle corrugation 63 and the end interface corrugation 61 of the bellows 6 (the two ends of the bellows 6 usually need to be welded, so the special flattening treatment of the interface corrugation 61 can effectively increase the strength and ease of processing of the welding).

[0040] Preferably, elastic parts are connected between the first mold 44 and the first mold mounting plate 410, and between the second mold 45 and the second mold mounting plate 411, and the first mold 44 and the second mold 45 are both provided with a plurality of limiting holes 412. The limiting parts 413 are passed through the limiting holes 412 and fixed to the first mold mounting plate 410 and the second mold mounting plate 411, so that the first mold 44 and the second mold 45 can move along the axial direction of the limiting parts 413.

[0041] Specifically, by pushing the first mold 44 and the second mold 45 by the elastic member and limiting the height of the first mold 44 and the second mold 45 by the limiting member 413, the first mold 44 and the second mold 45 initially have a certain lifting distance, and the initial lifting distance is the gap between the mold and the mold mounting plate. Then, by adjusting the positioning depth of the limiting member 413, the limiting height of the mold by the limiting member 413 can be controlled to facilitate the adjustment of the gap distance between the mold and the mold mounting plate, thereby ensuring precise adaptation of the interface corrugations 61 of different thicknesses.

[0042] In one embodiment of the present scheme, the elastic member may adopt a spring structure; the limiting member 413 may adopt a bolt structure, and the end of the limiting member 413 is threadedly engaged with the first mold mounting plate 410 or the second mold mounting plate 411 to ensure the adjustable height effect when the limiting member 413 is screwed. At the same time, no threaded engagement is set between the limiting member 413 and the limiting hole 412, but the limiting member 413 and the limiting hole 412 are movable engaged, so that the mold can be pressed and moved along the axial direction of the limiting member 413, thereby flattening the interface corrugation 61 of the bellows 6.

[0043] In particular, the limiting member 413 of this solution can be additionally provided with a guide ring on the periphery of the position where it cooperates with the limiting hole 412, so that when the mold is pressed, the movement and cooperation between the limiting hole 412 and the limiting member 413 can be used more smoothly through the guide ring.

[0044] Preferably, the first driving member 47 has a fixed block 414 on one side, and the fixed block 414 is detachably connected to a fixed base 415 so that the shaping upper mold 51 and the shaping lower mold 48 are both clamped between the fixed base 415 and the fixed block 414 .

[0045] Specifically, since the inner diameter, outer diameter processing requirements and other dimensions of the bellows 6 of different specifications are different, in order to accurately adapt to the bellows 6 of different specifications, this solution clamps and positions the shaping upper mold 51 and the shaping lower mold 48 through the setting of the fixed base 415 and the fixed block 414, and the style of the shaping upper mold 51 and the shaping lower mold 48 can be conveniently replaced by disassembling the fixed base 415 to ensure the adaptation effect of the bellows 6.

[0046] In one embodiment of this solution, the fixing base 415 and the fixing block 414 are threadedly engaged with each other.

[0047] Preferably, a positioning arc plate 416 is extended on the inner side of the groove 46 so that when the bellows 6 is processed, the interface corrugation 61 at one end of the bellows 6 is located between the end face of the shaping lower mold 48 and the positioning arc plate 416, and the interface corrugation 61 at the other end of the bellows 6 is located between the end face of the shaping upper mold 51 and the positioning arc plate 416.

[0048] Specifically, when the groove 46 clamps and limits the outer periphery of the bellows 6 along with the die, the positioning arc plate 416 is clamped between the interface corrugation 61 at the end of the bellows 6 and the adjacent corrugation, that is, the interface corrugation 61 is located between the positioning arc plate 416 and the end face of the shaping upper die 51 or the lower die 48. At this time, in the process of the groove 46 wrapping the outer periphery of the middle section corrugation 63 of the bellows 6 and the lifting seat 3 pressing down, there are two stages of flattening processing: ① The lifting seat 3 is pressed down, so that the first mold assembly 4 and the second mold assembly 5 are close to each other. At this time, the middle section corrugation 63 of the bellows 6 is close to the outer periphery of the bellows 6. 63 is flattened and shaped until the dies in the first mold assembly 4 and the second mold assembly 5 abut against each other; ② the lifting seat 3 continues to press down. Since the dies in the first mold assembly 4 and the second mold assembly 5 abut against each other at this time, the dies will be compressed and approach the die mounting plate (compressed elastic parts), so that the positioning arc plate 416 and the end face of the shaping upper mold 51 or the lower mold 48 are flattened at the position of the interface corrugation 61, and the flattening stroke of the interface corrugation 61 is the downward stroke of the lifting seat 3 in the second stage / 2 (the upper and lower ends of the bellows 6 are flattened synchronously).

[0049] In a preferred embodiment of the present scheme, the end face of the shaping upper mold 51 or the lower mold 48 is set higher than the end face of the fixed base 415 to avoid the problem that when the positioning arc plate 416 is pressed down, the positioning arc plate 416 is interfered with by the end face of the fixed base 415, resulting in inaccurate flattening stroke of the interface corrugation 61.

[0050] Preferably, a first gasket 417 for increasing the thickness of the first mold 44 is connected to the side of the first mold 44 close to the second mold assembly 5, and a second gasket 418 for increasing the thickness of the second mold 45 is connected to the side of the second mold 45 close to the second mold assembly 5.

[0051] Specifically, by adding the first gasket 417, the thickness of the first mold 44 can be increased (the first gasket 417 and the first mold 44 are regarded as the same unit), so that when the first mold assembly 4 and the second mold assembly 5 are close to each other to flatten and shape the middle corrugation 63 of the bellows 6, the flattening height of the middle corrugation 63 can be adjusted by the first gasket 417 to ensure the accuracy of the total height of the bellows 6 after flattening and shaping.

[0052] It is worth mentioning that when the mold pieces in the first mold assembly 4 and the second mold assembly 5 abut against each other, the flattened molding height of the middle corrugation 63 is reached. At this time, the flattened height of the middle corrugation 63 is the mold piece (first mold assembly 4) + gasket (first mold assembly 4) + mold piece (second mold assembly 5) + gasket (second mold assembly 5). Therefore, by controlling the thickness of the gasket, the flattening processing size of the middle corrugation 63 can be quickly changed without adjusting the mold piece size, thereby improving the overall processing efficiency.

[0053] Among them, the thickness of the first gasket 417 and the second gasket 418 needs to be consistent to ensure that the flattening height on both sides of the bellows 6 is consistent, and the first gasket 417 and the second gasket 418 are also provided with a groove 46, which has the same structure as the groove 46 on the mold.

[0054] Preferably, the frame 1 is provided with a second driving member 11 for driving the lifting seat 3 , and a plurality of guide posts 12 are provided on the side of the lifting seat 3 , and the guide posts 12 are in movable cooperation with the frame 1 .

[0055] Specifically, the lifting seat 3 is controlled to move up and down relative to the frame 1 by the second driving member 11. At this time, the guide column 12 can be used to guide the lifting direction of the lifting seat 3 to improve the matching accuracy between the first mold assembly 4 and the second mold assembly 5.

[0056] In one embodiment of this solution, the second driving member 11 may be a servo cylinder, and the lifting base 3 is connected to the output end of the servo cylinder so that the servo cylinder can control the lifting movement of the lifting base 3 .

[0057] Preferably, a plurality of adjustment slots 21 are provided on the working platform 2 and the lifting seat 3 , and the mold mounting plate 41 is detachably connected to the adjustment slots 21 .

[0058] Specifically, by setting the adjustment groove 21, the mold mounting plate 41 can be positioned at any position in the adjustment groove 21 to adjust the relative position relationship between multiple mold mounting plates 41. When it is necessary to remove or install the mold mounting plate 41, it can be adjusted by moving the original mold mounting plate 41 along the adjustment groove 21.

[0059] In one embodiment of the present scheme, a plurality of mounting holes corresponding to the adjustment grooves 21 are opened on the side of the mold mounting plate 41. The mold mounting plate 41 can be positioned by passing parts such as tightening bolts through the mounting holes and tightening them to the adjustment grooves 21.

[0060] Preferably, the side of the frame 1 has an interactive interface 13 for controlling the opening and closing status of the bellows 6 processing, so that the operator can control the opening and closing, processing size parameters, etc. of the equipment of this scheme through the interactive interface 13, and its specific control method can adopt existing control methods such as PLC control program.

[0061] When using this solution, you can follow the following process: The semi-finished bellows 6 is sleeved onto the guide rod 49 of the shaping lower mold 48, and the lower end of the bellows 6 is placed on the end surface of the shaping lower mold 48. The interactive interface 13 controls the extension of the screw of the servo electric cylinder, and then controls the second mold assembly 5 to move downward to the pre-compression position through the lifting seat 3, so that the lower end surface of the shaping upper mold 51 contacts the upper end of the semi-finished bellows 6, and then pre-compressed by 0-0.3mm (since there may be a certain error in the height of the semi-finished bellows 6, this action can effectively eliminate the height error between different semi-finished bellows 6). The interactive interface 13 controls the cylinder to close (that is, the first slider 42 and the second slider 43 approach each other), and the positioning arc plate 416 is inserted between the interface corrugation 61 of the semi-finished bellows 6 and the adjacent corrugation. The interface corrugation 61 at the lower end of the bellows 6 is located between the mold piece and the upper end surface of the shaping lower mold 48, and the interface corrugation 61 at the upper end of the bellows 6 is located below the mold piece and the shaping upper mold 51. Between the end faces, the delivery interface controls the screw of the servo electric cylinder to extend twice, driving the second mold assembly 5 and the shaping upper mold 51 downward to the compression position. At this time, the mold pieces in the first mold assembly 4 and the second mold assembly 5 are pressed against each other under the action of the servo electric cylinder, and the thickness of the mold piece (mold piece + gasket) limits the forming height of the middle corrugation 63. The screw of the servo electric cylinder extends three times, and the mold piece and the shaping lower mold 48 or the shaping upper mold 51 squeeze the interface corrugation 61 against each other until the interface corrugation 61 is flattened to the required thickness and formed into a flattened wave 62. The delivery interface controls the screw of the servo electric cylinder to retract, and drive the second mold assembly 5 and the shaping upper mold 51 to move to the pressure relief mold opening position. The mold piece is reset under the action of the ejection force of the elastic part, the cylinder opens, and the mold piece disengages from the finished bellows 6. The screw of the servo electric cylinder is controlled to retract, and drive the second mold assembly 5 and the shaping upper mold 51 to move to the initial position, take out the finished bellows 6, and complete a cycle.

[0062] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
