The utility model also provides a high-efficient compound die or form removal method, the compound die is different with the processing of form removal only to the bolt in S3, all the other homogeneous phases. The method specifically comprises the following steps:

s1: the pipe die is moved on the conveying line in the X direction, and when the pipe die moves into the outer frame 3, the second sensor on the outer frame 3 detects the height of the pipe die, or the second follow-up bracket 84 is driven by the follow-up second lifting device 81 to descend to a preset height corresponding to the height of the pipe die according to the height of the pipe die which is manually input in advance. The piston rod of the follower lift lock driving mechanism 821 horizontally extends out and is inserted into the positioning hole 823 at the same height, so that the second follower support 84 is kept at a preset height. In addition, the following X-direction lock 86 is always in a locked state. S2 is executed.

S2: and when the pipe die moves to the associated position relative to the die closing machine, the die closing machine and the pipe die are associated with each other so as to move synchronously along the X direction along with the pipe die.

The related position, namely the position of the centrifugal position flange 18 convenient to fix on the pipe die, is used for judging whether the pipe die moves to the position of the centrifugal position flange 18 relative to the die spotting machine, and the method comprises the following steps: as shown in fig. 13, the following first elevating device 88 drives the holding device to descend, so that the first sensor 893 on the clamping fixture 892 descends to a height opposite to the eccentric location flange 18 on the pipe die in the X direction, and detects the distance from the eccentric location flange 18 in the X direction. When the distance is less than a predetermined value, it is determined that the eccentric flange 18 has been reached. The predetermined distance should be set small so that clamping fixture 892 is in close proximity to eccentric cam 18 so as to clamp eccentric cam 18.

As shown in fig. 14, the clamp driving mechanism 891 of the clamp device drives the movable clamp arm 8911 thereof to rotate downward, the centrifugal flange 18 is clamped between the movable clamp arm 8911 and the clamp fixing member 892, the clamp device is fixed to the centrifugal flange 18 to associate the outer frame 3 with the pipe die, and at the same time, the clutch 214 of the travel driving mechanism 21 is switched to the disengaged state, and the outer frame 3 is dragged by the pipe die to move synchronously in the X direction. S3 is executed.

S3: the three-dimensional moving unit drives the inner frames 5 on each side to move to the notch position, the bolt overturning unit 7 and the nut screwing unit 6 on each inner frame 5 respectively assemble and disassemble bolts at each notch, if the quantity of the bolts required to be assembled and disassembled on each side is larger than that of the inner frames 5, the inner frames 5 are continuously driven to the unassembled bolts by the X-direction moving device until all the bolts near the eccentric flange 18 are completely assembled and disassembled. S4 is executed.

S4: the X-direction lock 86 is then actuated to release the lock on the X-direction rail 841. As shown in fig. 15, the first follower bracket 87 is driven by the follower X-direction moving device 85 to move on the X-direction guide 841, and since the first follower bracket 87 is fixed to the pipe mold by the holding device and the movements thereof are opposite to each other, the effect is that the X-direction guide 841 moves in the X-direction with respect to the first follower bracket 87 and the holding device, and since the second follower bracket 84 on which the X-direction guide 841 is located is fixed in the X-direction with respect to the outer frame 3, the outer frame 3 is moved in the X-direction to the second position with respect to the first follower bracket 87 and the holding device. After the movement is finished, the follow-up X-direction locking device 86 is locked again, and the bolt on the notch position is assembled and disassembled by the assembling and disassembling unit.

Then, the outer frame 3 can be driven by the following X-direction moving device 85 to move to a third position, a fourth position, and the like for assembly and disassembly, and is specifically arranged according to the interval of the centrifugal flanges 18 of the pipe mold, so that the moving range of the outer frame 3 on the pipe mold can cover all the bolts between every two centrifugal flanges 18, and all the bolts can be assembled and disassembled, and the situation that partial bolts between the two centrifugal flanges 18 cannot be assembled and disassembled due to the overlong distance between the two centrifugal flanges 18 and the smaller coverage range of the pipe mold by the outer frame 3 is avoided.

After the attachment and detachment of the bolts near the eccentric flange 18 are completed, the outer frame 3 is driven to return to the initial position by the following X-direction moving device 85.

S5: the clamping driving mechanism 891 drives the movable clamping arm 8911 to rotate upwards, so that the clamping device releases the eccentric flange 18, and the follow-up first lifting device 88 drives the clamping device to lift, so that the outer frame 3 is separated from the pipe die, and the pipe die moves relative to the die spotting machine. S5 is executed.

S6: the pipe die is moved relative to the outer frame 3 so that the next eccentric flange 18 on the pipe die reaches the outer frame 3. In the process, the clutch 214 is switched to the engaged state, and the walking driving device 21 drives the outer frame 3 to follow the pipe die on the track 9, so as to prevent the pipe die from being conveyed too fast and missing the next eccentric flange 18; if the moving speed of the pipe die is slow, the walking driving device 21 can be omitted, and the die spotting machine can be static on the rail 9 to wait for the pipe die to move continuously. At the same time, S2 is executed again, the first sensor 893 is lowered again to detect whether the next eccentric flange 18 is in place, and after the flange is in place, the flange is clamped again and then the mounting and dismounting are performed. And performing the steps S2-S5 in a circulating manner until all the bolts on the pipe die are machined.

In other embodiments, the associating device may implement the association between the mold closing machine and the pipe mold by other means than a clamping device, such as a magnetic or vacuum chuck, and when such a chuck is used, the chuck may be directly sucked and fixed with the flat portion of the top of the pipe mold, and does not need to be fixed with the raised portion, so that the raised portion does not need to be detected. The first sensor 893 may be fixed at another location on the clapper die spotting press to detect the raised area in another manner. The follow-up second elevating device 81 and the follow-up elevating locking device 82 can be omitted. The following lifting locking device 82 may be locked without the combination of the positioning hole 823 and the piston rod, and may be any structure that can be combined with each other to achieve locking. Similarly, the following X-direction locking device 86 may be omitted or implemented by other locking structures.

What has been described above are only some embodiments of the invention.
