As shown in figure 3, being also provided with the kidney slot 20323 for allowing expanding rod to pass through on the jam plate 2032, expanding rod being allowed to limit
The kidney slot 20324 that position boss 2012 passes through.
The first ladder expanding rod locking assembly 205, the second ladder expanding rod locking assembly 207 and expanding rod hang locking group
The structure composition of part 210 is identical as the structure composition of expanding rod locking assembly 203, also include mounting plate, jam plate, jam plate cover board and
Jam plate driving assembly is intended merely to the different needs of cooperation 2012 position of positive stop lug boss different expanding rod and workpiece ladder, different
It the position of the lockhole on jam plate, kidney slot in locking assembly can be different.
The guidance set 208 includes guide rod 2081, guiding deckle board 2082, guide sleeve 2083, bumper post 2084, chain
(not shown).
Described 2081 one end of guide rod is mounted in flare seat 302, and the other end is mounted on hanging seat 209, the guide sleeve
2083 are set on outside guide rod 2081 and are oriented in deckle board 2082, and are mounted on guiding deckle board 2082, the bumper post 2084
It is mounted on guiding deckle board 2082.It is connected between each guiding deckle board 2082 by chain, two of them are oriented to deckle board
2082 are connect with the first ladder power seat 204 and the second ladder power seat 206 respectively by chain.
It is mobile steady in order to make to be oriented to deckle board, it is provided with sliding block sliding rail between each guiding deckle board 2082 and fuselage 1 and leads
To mechanism 2086.
When tube expansion, expanding rod 201 as needed is divided into two parts, and a part carries out tube expansion, and a part is without tube expansion.No
It hangs the right side that positive stop lug boss 2013 is located at expanding rod suspension locking assembly 210 with the expanding rod 201 ' of progress tube expansion, and by its jam plate
Locking, expanding rod when tube expansion without tube expansion will not then be moved together with power seat 202, Yao Jinhang tube expansion then in left side, shape
State figure is as shown in Figure 7.
The stepped workpiece of three rows as shown in FIG. 6 is corresponded with the three row of the bulge bars 201 of Fig. 7 from top to bottom, each to arrange
Expanding rod 201 be locked component locking state diagram as shown in fig. 7, three row of the bulge bars are in sustained height position.After adjusting,
To carry out tube expansion movement, power seat 202 drives three row of the bulge bars 201 are mobile to carry out tube expansion, and three array of pipes quilt is swollen simultaneously on earth, herein
In the process, the first ladder power seat 204 is mobile relative to power seat with certain speed simultaneously, and directional velocity is identical, and second-order
Terraced power seat 206 is also mobile with respect to power seat with certain speed simultaneously, directional velocity on the contrary, so interior at the same time,
The corresponding 201 tube expansion speed of expanding rod of the pipe of one row of longest is fast, the corresponding 201 tube expansion speed of expanding rod of the pipe of a most short row
It can be most slow.After three row of workpiece all it is swollen it is complete after, power seat 202 returns to initial position, in the process, the first ladder power seat
204 is mobile relative to power seat with certain speed simultaneously, and directional velocity is identical, and the second ladder power seat 206 is also simultaneously with one
Fixed speed is mobile relative to power seat, and for directional velocity on the contrary, so at the same time, the pipe of one row of longest is corresponding
201 tube expansion speed of expanding rod is fast, and the corresponding 201 tube expansion speed of expanding rod of the pipe of a most short row can be most slow, wants the swollen of tube expansion in this way
Bar 201 returns to same position simultaneously again, waits for tube expansion next time.
If workpiece height is the same, i.e., usually said putting down is swollen, then the first ladder power seat 204 and the second ladder power
Seat 206 does not need then to move, and can also save.
During power seat 202 moves forward tube expansion, the second ladder power seat 206 passes through chain 2085 for second-order
Guiding deckle board 2082 between terraced power seat 206 and hanging seat 209 gradually pulls open the expanding rod 201 ' to support non-tube expansion, while first
Guiding deckle board 2082 between ladder power seat 204 and flare seat 302 with the expanding rod 201 of tube expansion gradually protrude into workpiece and by
Compression contact, is contacted by bumper post 2084 between each other, and the directly touching of guiding deckle board 2082 is avoided to vibrate.
When 202 tube expansion of power seat terminates to retract, with above-mentioned movement on the contrary, the first ladder power seat 204 passes through chain
2085 by the guiding deckle board 2082 between the first ladder power seat 204 and flare seat 302 as the expanding rod 201 of tube expansion gradually exits
Workpiece and pull open, support and be oriented to, retract the expanding rod 201 of tube expansion, and between the second ladder power seat 206 and hanging seat 209
Guiding deckle board 2082 is then gradually compressed.

Between 3047, at this point, flaring assembly initialization component 305 is started to work, 3051 piston rod of cylinder is retracted, and spring 3053 will receive
Compression, due to the barrier effect of circlip 310, so that spring 3053 drives flaring component 303 mobile, until elasticity is kept off
Circle 310 is blocked by the 5th guide plate 306 until cannot continuing to move to, this just carries out the flaring component 303 for needing to be flared
Initialization, makes it be entirely located in same position, and then the second jam plate driving assembly 30412 drives the second jam plate 3043 mobile, makes
First flaring component 303 ' to be flared of the latching of aperture 34 of second jam plate 3043, and the flaring component that second batch to be flared
303 " are then located in long gain hole 35, and state diagram is as shown in 14 and 15.In flaring, flare seat 302 drives flaring component 303 '
It is mobile to complete its flaring to corresponding nozzle, and it is flared component 303 " due in long gain hole 35, not being flared power, it will not be right
Its corresponding nozzle is flared, and is also pushed back instead.
First flaring is completed, and flare seat 302 is retracted, and the second jam plate 3043 unclamps.
Under the action of spring 3053, flaring component 303 " also resets, and the flaring component for needing to be flared is located at same again
Position, then third jam plate driving assembly 30413 drives third jam plate 3045 mobile, locks the aperture 34 of third jam plate 3043
The second batch flaring component 303 " to be flared, and the flaring component 303 ' of first flaring is then located in long gain hole 35.Expanding
Mouthful when, flare seat 302 drives flaring component 303 " is mobile to complete its flaring to corresponding nozzle, and be flared component 303 ' due to
In long gain hole 35, it is not flared power, its corresponding nozzle will not be flared, be also pushed back instead.Second batch has been flared
At flare seat 302 is retracted, and the second jam plate 3043 unclamps.
The flaring thus to have made two bites at a cherry to all nozzles.
If once to complete the flaring to all nozzles, as long as by the second jam plate and the mobile latching institute of third jam plate
Some is wait be flared component.
