The present invention softens the pipe through a heating mechanism when the pipe is flanging to prevent the pipe from cracking during the flanging process. When the pipe is flanging, the bending radius length during flanging is automatically adjusted according to the changes in the thickness and diameter of the pipe.

Description

Technical Field

[0001] The invention belongs to the technical field of glass fiber reinforced plastic composite pipe processing, and in particular relates to a fully automatic flanging device for a glass fiber reinforced plastic composite pipe. Background Art

[0002] The flanging of the FRP composite pipe is to fold the pipe wall outward to increase the strength and connectivity of the pipe end. The flanging of the FRP composite pipe should generally not exceed 90° to avoid excessive deformation or cracking of the pipe end face, which will affect the normal use of the pipe. The pipe end after flanging presents a funnel-like shape, which can improve the pressure and bearing capacity of the pipe.

[0003] FRP composite pipes are prone to cracking during the flanging process due to their poor plasticity. Sufficient length must be reserved at the pipe mouth so that it can withstand relatively large pressure during the flanging process. However, for pipes of the same diameter and larger thickness, the required bending radius length will be relatively long when flanging at the same angle. For pipes of the same thickness and larger diameter, the required bending radius length will also be relatively long when flanging at the same angle.

[0004] Therefore, different bend radius lengths need to be reserved during flanging according to different pipe diameters and wall thicknesses to prevent cracking, but the prior art cannot reserve different bend radius lengths during flanging of FRP composite pipes according to different pipe diameters and wall thicknesses.

[0041] When the present invention is used to flanging the glass fiber reinforced plastic composite pipe, the electric fan 6 is started, and then the pipe is moved toward the interior of the present invention. During the movement, the gas blown out by the electric fan 6 moves forward through the second conduit 602. The front end of the second conduit 602 is in contact with the front side of the first shell 606 under the action of the spring 603 at the initial position. At this time, the gas enters the first shell 606 through the second conduit 602. The gas enters the first sliding block 6061 through the telescopic pipe in the first shell 606. The first sliding block 6061 sprays gas to blow out impurities in the pipe to prevent the impurities from damaging the pipe during flanging. In the process of the pipe entering the interior of the present invention, the pipe squeezes the first The sliding block 6061 and the second sliding block 6062 move, and the first sliding block 6061 drives the first limit block 301 to move, so that the first limit block 301 fits with the pipe, and continues to move when the edge of the pipe contacts the second limit rod 605, and the pipe drives the second limit rod 605 to move backward, and the second limit rod 605 drives the second conduit 602 to move backward. At this time, the conical air outlet at the front end of the second conduit 602 cooperates with the sealing block in the first shell 606 to seal the front end of the second conduit 602 and turn off the electric fan 6. At this time, the pipe reaches the flange position and stops moving. When the pipe is successfully moved out, the fixing ring 604 and the second limit rod 605 rebound under the action of the spring 603, and the cleaning mechanism is reset.

The pipe rotates under the action of the directional rotation mechanism, so that the pipe is evenly flanging. The second fixed rod 3051 drives the first sleeve 3052 to move. In order to prevent the second fixed rod 3051 from rubbing against the inner wall of the pipe during flanging and causing damage to the pipe, the first sleeve 3052 turns off the rotating motor 2 after the flanging is completed. After the rotating motor 2 is turned off, the rotating ring 202 stops rotating. At this time, the pipe is unlocked by rotating the fixed handle 205. After the pipe is unlocked, the pipe is moved out. In the process of the pipe moving forward, the bent edge of the pipe will press the first limit block 301 on the outside, so that the pipe is smoothly moved out to complete the flanging.

[0046] After the pipeline enters the interior of the present invention and presses the fixing ring 604, the fixing ring 604 drives the first conduit 601 to move backward. In the initial position, the front end of the first conduit 601 is located inside the second shell 607, and the sealing member on the second shell 607 seals the front end of the first conduit 601. After the fixing ring 604 is pressed, the front end of the first conduit 601 is separated from the sealing member of the second shell 607. After the pipeline is clamped under the action of the rotating screw 204, the electric fan 6 is started, and the gas moves to the inside of the second shell 607 through the first conduit 601. The gas inside the second shell 607 enters the airbag 608 through the circular hole, and the airbag 608 expands and becomes The large support rod 610 moves outward, the support rod 610 drives the elastic telescopic rod 609 to extend outward, the support rod 610 drives the second sleeve 611 to move outward, the airbag 608 expands to make the second sleeve 611 contact with the inner wall of the pipe and then stops, at this time the airbag 608 is closed, the airbag 608 is limited by the support rod 610 close to the airbag 608, the second sleeve 611 contacts with the rotating pipe, and the gap between the support rod 610 close to the airbag 608 and the second sleeve 611 prevents the airbag 608 from directly contacting the pipe, thereby protecting the airbag 608, and the airbag 608 opens to block the pipe, thereby hindering the gas circulation inside the pipe.

[0047] Open the switch valve on the third duct 702, and the electric fan 6 starts to blow out hot air after the air bag 608 expands.

[0048] After the pipeline enters the interior of the present invention, the first hydraulic rod 3 is compressed, and the first hydraulic rod 3 drives the first moving rod 304 to move through the first limiting rod 303. The first moving rod 304 compresses the hydraulic oil in the first hydraulic chamber 502 inwardly, and the hydraulic oil in the first hydraulic chamber 502 moves to the inside of the annular hydraulic shell 504 through the L-shaped conduit 503. The second elastic member 5041 presses the annular seal inside the annular hydraulic shell 504 outwardly, and the hydraulic oil in the annular hydraulic shell 504 is moved to the inside of the second hydraulic chamber 506 through the hydraulic conduit 505 through the second elastic member 5041. The increase of hydraulic oil in the second hydraulic chamber 506 presses the second moving rod 507 to slide inwardly, so that the first limiting block 301 fixed to the second moving rod 507 is aligned with the outside of the pipeline. Wall contact, in the initial state, the hydraulic oil inside the first hydraulic chamber 502 and the annular hydraulic shell 504 and the second hydraulic chamber 506 is constant. In the initial state, the second elastic member 5041 presses the annular hydraulic shell 504, and the liquid in the annular hydraulic shell 504 enters the first hydraulic chamber 502 and the second hydraulic chamber 506. The increase of liquid in the first hydraulic chamber 502 and the second hydraulic chamber 506 drives the first moving rod 304 and the second moving rod 507 to move. The first moving rod 304 drives the first limiting rod 303 to make the two corresponding first limiting blocks 301 inside and outside contact. At this time, the limiting slider 501 contacts the front side of the sliding groove of the second limiting block 5. When a pipeline enters, the first limiting block 301 moves to make the first limiting rod 303 and the pressing block 307 move. A limiting rod 303 drives the first moving rod 304 to move. At this time, the total amount of hydraulic oil in the first hydraulic chamber 502 and the second hydraulic chamber 506 decreases, and the hydraulic oil in the annular hydraulic shell 504 increases. The annular seal in the annular hydraulic shell 504 moves backward and drives the L-shaped guide tube 503 to move backward. The L-shaped guide tube 503 drives the limiting slider 501 to slide backward in the slide groove of the second limiting block 5. The limiting slider 501 drives the first hydraulic chamber 502 to move. The first hydraulic chamber 502 drives the first moving rod 304 to move. The first moving rod 304 slides on the first limiting rod 303 and drives the connecting member 305 to move inward. The connecting member 305 drives the second fixed rod 3051 to move inward, and the connecting member 305 is separated from the first limiting block 301 on the inner side. , the length of the pipe bending radius is extended, the oil inlet hole of the second hydraulic chamber 506 is closed, and when the pipe is flanging, the first limiting rod 303 is fixed so that the volume of the hydraulic oil in the first hydraulic chamber 502 remains unchanged, the volume of the hydraulic oil in the annular hydraulic shell 504 remains unchanged, and the front and rear positions of the first moving rod 304 remain unchanged, so as to prevent the second fixed rod 3051 from shaking during flanging, so that when folding pipes of different thicknesses, the thicker the pipe, the longer the bending radius length, the diameter of the second hydraulic chamber 506 is greater than the diameter of the first hydraulic chamber 502, and when the pipe thickness is the same and the diameter increases, the second hydraulic chamber 506 and the first hydraulic chamber 502 move outward by the same distance, the total amount of hydraulic oil in the second hydraulic chamber 506 and the first hydraulic chamber 502 decreases, and the hydraulic oil in the annular hydraulic shell 504 increases,The movement of the annular seal in the annular hydraulic housing 504 drives the second fixing rod 3051 to move inward, and the length of the bend radius increases. The length of the bend radius is automatically adjusted through the transfer of hydraulic oil in the first hydraulic chamber 502, the annular hydraulic housing 504, and the second hydraulic chamber 506, to prevent breakage and damage when the pipeline is folded.
