Description

Technical Field

[0001] The present invention relates to the field of flange processing, and in particular to a flange processing device. Background Art

[0002] As an important component for connecting pipeline systems, mechanical equipment, and pressure vessels, flanges are widely used in many fields such as petrochemical, electric power, shipbuilding, metallurgy, aerospace, etc.; their processing quality directly affects the sealing performance and structural stability of the entire system. When processing and manufacturing flanges, turning equipment is required to perform cutting work on the flanges, that is, a turning tool turns the rotating flange to remove the excess metal on the flange blank for forming the flange.

[0003] In the related art, a flange processing turning equipment includes an equipment base; a fixed seat is fixedly connected to the top of the equipment base; a servo motor is fixedly connected inside the fixed seat; the output end of the servo motor is fixedly connected to a rotating roller; a first limiting plate is fixedly connected to the rotating roller, and a second limiting plate is threadedly connected to the end of the rotating roller away from the servo motor. The flange is sleeved on the rotating roller and is located between the first limiting plate and the second limiting plate. An installation cavity is formed inside the rotating roller, and a plurality of extrusion blocks are slidably installed on the rotating roller. The plurality of extrusion blocks extend into the installation cavity. A push rod extending into the installation cavity is fixedly connected to the second limiting plate. A spherical surface in contact with the plurality of extrusion blocks is formed on the push rod. During the rotation of the second limiting plate, the second limiting plate pushes the extrusion blocks to move through the push rod, so that the extrusion blocks are in contact with the inner wall of the flange, thereby limiting the flange. A linear moving mechanism is installed on the equipment base, and a turning tool is installed on the linear moving mechanism. The linear moving mechanism drives the turning tool to move to turn the flange.

[0004] In view of the above related art, during the turning of the flange, the flange is fixed only by the friction between the extrusion blocks and the flange. If the force applied by the extrusion blocks is too large, it may damage the flange.

When the locking inclined surface contacts the connecting block 58, the locking block 62 contracts into the locking installation groove, compressing the locking spring 61. When the locking block 62 is opposite to the locking insertion groove, the locking spring 61 pushes the locking block 62 into the locking insertion groove to lock the connecting block 58. At the same time, the abutting plate 24 contacts the flange. After the turning of the flange is completed, the driving motor 41 is started to reverse. The driving motor 41 drives the alignment guide rod 23 to move in the reverse direction. The alignment guide rod 23 drives the connecting block 58 to move. The connecting block 58 drives the second switch 57 to move, stretching the third spring 59. At this time, the second switch 57 still contacts the first switch 56. When the alignment guide rod 23 moves to the initial position, the second switch 57 is separated from the first switch 56, and the driving motor 41 returns to the initial position. The driving motor 41 drives the two alignment plates 22 to approach each other.

When the alignment guide rod 23 moves to the initial position, the second switch 57 is separated from the first switch 56, and the two alignment plates 22 approach each other. When the L-shaped insertion rod 63 contacts the matching inclined surface, the L-shaped insertion rod 63 pushes the unlocking rod 64 to move. The unlocking rod 64 pushes the locking block 62 to move through the unlocking inclined surface, so that the locking block 62 is pulled out of the locking insertion groove, and the locking of the connecting block 58 can be released.

[0039] The implementation principle of a flange processing device according to an embodiment of the present invention is as follows: When turning a flange, first place the flange on the alignment shaft 21, and then start the drive motor 41. The drive motor 41 drives the two alignment plates 22 to move away from each other. When both alignment plates 22 come into contact with the flange, the two alignment plates 22 support the flange. At the same time, the control block 55 is completely received in the control groove, the first switch 56 contacts the second switch 57, and the storage battery energizes the electromagnet 51. The electromagnet 51 attracts the iron block 52, and the iron block 52 drives the drive motor 41 to move, so that the first gear 411 disengages from the second gear 451, and the first gear 411 meshes with the third gear 351. The drive motor 41 drives the limit plate 31 to move, and at the same time the limit plate 31 rotates. The limit plate 31 drives the buffer column 33 to insert into the bolt hole on the flange, and the drive motor 41 drives the abutting plate 24 to move. The abutting plate 24 and the limit plate 31 cooperate to limit the flange from both sides. At this time, the alignment guide rod 23 is locked with the connecting block 58.

[0040] After the turning of the flange is completed, start the drive motor 41 to reverse. The drive motor 41 drives the limit plate 31 and the alignment guide rod 23 to move in the reverse direction. The alignment guide rod 23 drives the connecting block 58 to move, and the connecting block 58 drives the second switch 57 to move, stretching the third spring 59. At this time, the second switch 57 still contacts the first switch 56. When the alignment guide rod 23 moves to the initial position, the second switch 57 separates from the first switch 56, and the drive motor 41 returns to the initial position. The drive motor 41 drives the two alignment plates 22 to move closer to each other. When the two alignment plates 22 return to the initial position, the L-shaped insertion rod 63 pushes the unlocking rod 64 to move. The unlocking rod 64 pushes the locking block 62 to move through the unlocking inclined surface, so that the locking block 62 is pulled out of the locking insertion slot, unlocking the locking of the connecting block 58. The third spring 59 drives the connecting block 58 to return to the initial position, facilitating continued use next time.

[0041] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
