Heating pipes are arranged in the first movable template 21, the second movable template 31, the first fixed template 22 and the second fixed template 32.
Further, in order to reduce the volume of the whole equipment for field operation, as shown in fig. 1 and 2, the C-shaped frame body includes a bottom plate 11, and two C-shaped plates 12 with openings facing the front side are arranged on the bottom plate 11 in parallel. As shown in fig. 5 and 6, the left and right ends of the first and second fixing templates 22 and 32 are fixedly connected to the C-shaped plate 12, respectively. As a specific embodiment, in this embodiment, a first boss 221 and a second boss 321 extending inward are respectively disposed on the inner side surfaces (on the side close to the C-shaped frame) of the first fixing template 22 and the second fixing template 32, and the dimensions of the first boss 221 and the second boss 321 in the left-right direction are equal to the distance between the two C-shaped plates 12.

Preferably, a certain distance M is provided between the lower side of the connection lug 13 and the upper side of the opening of the C-shaped plate 12. The upper side of the end connecting plate is pressed against the upper side of the opening of the C-shaped plate 12 under the locking action of the second screw. The left and right ends of the end connecting plate of the second cylinder 33 are fixedly connected with the rear end surface of the C-shaped plate 12 through third screws respectively.
Therefore, the oil cylinder can be used for strengthening the frame body, namely, the oil cylinder has the function and the strengthening member.
Further, in order to make the structure more stable, the atress is more reasonable. Two guide rods are arranged on the left side and the right side of the C-shaped frame body, and four guide rods are arranged in a matrix of two rows and two columns. For convenience of description, the guide bar on the upper side will now be defined as an upper guide bar 36, and the guide bar on the lower side will be defined as a lower guide bar 37. However, although stability can be increased, since the sealing ring after butt joint is in a closed-loop state, the sealing ring can only enter between the second movable die plate 31 and the second fixed die plate 32 through a gap between two adjacent guide rods in order to be able to remove the sealing ring which is finally in the closed-loop state. Thus, the problem of deformation of the sealing ring with larger diameter can exist, and the final processing quality is affected.
For this reason, as shown in fig. 10 and 11, the diameters of the through holes for receiving the upper guide bar 36 in the second moving die plate 31 and the first connecting plate 34 are the same as the diameter of the upper guide bar 36. A detachable cushion block 38 is disposed on the upper guide bar 36 at the front side of the second movable mold plate 31, and the cushion block 38 determines the limit position of the second movable mold plate 31 moving forward relative to the upper guide bar 36.
As a specific embodiment, flat openings 361 are symmetrically arranged on the upper guide rod 36 at the front side of the second moving die plate 31 in this embodiment, as shown in fig. 7 and 13, the length of the cushion block 38 is the same as the dimension of the flat openings 361 along the front-rear direction, and a notch 381 penetrating through the cushion block 38 along the length direction is arranged on the cushion block 38. The notch 381 includes two clamping planes 3811, and a distance between the two clamping planes 3811 is equal to a distance between the two flat openings 361. Preferably, the surface for connecting the two clamping planes 3811 is an arcuate surface 3812, and has the same diameter as the upper guide bar 36.
The rear side of the first connecting plate 34 is provided with a second connecting plate 35, and two ends of the second connecting plate 35 are respectively and fixedly connected with the upper guide rod 36. Preferably, the second connecting plate 35 is provided with a handle 351.
In this way, in use, the end of the sealing ring can be inserted from the gap between the upper guide rod 36 and the lower guide rod 37, after the butt joint is completed to form a closed loop, the cushion block 38 is removed from the upper guide rod 36, and the diameter of the upper guide rod 36 is equal to the diameter of the through hole in the second moving die plate 31 for accommodating the upper guide rod 36, so that the upper guide rod 36 can be separated from the second moving die plate 31 after the cushion block 38 is removed from the upper guide rod 36. At this time, the upper guide bar 36 is pushed backward, so that the upper guide bar 36 is separated from the second moving die plate 31, and the sealing ring forming the closed loop can be taken out.
Further, as shown in fig. 6, the front end of the first fixed die plate 22 is connected to the upper end of the second fixed die plate 32, and the first fixed die plate 22 and the second fixed die plate 32 together form an L-shaped structure.
Further, as shown in fig. 6 and 9, a supporting plate 15 for supporting the second cylinder 33 is disposed between the two C-shaped plates 12, and an arc-shaped groove matching the outer diameter of the second cylinder 33 is disposed on the supporting plate 15.
The operation method for replacing the sealing ring by the vulcanizing machine comprises the following steps:
first, a seal ring of matching dimensions is selected and comprises a fully vulcanised zone 41 and a semi vulcanised zone 42.
Preferably, the ratio of the arc length N of the semi-vulcanized area 42 to the perimeter L of the sealing ring is 1/10-1/8.
Here, the seal ring including the fully vulcanized region 41 and the semi-vulcanized region means that a partial region of the seal ring is in a fully vulcanized state, a partial region is in a semi-vulcanized state, and a region in a semi-vulcanized state is continuous as shown in fig. 14.
The sealing ring comprising the complete vulcanizing zone 41 and the semi-vulcanizing zone 42 belongs to the prior art in terms of the preparation process, namely the partially vulcanized sealing ring can be prepared by adopting the prior art. At present, manufacturers can customize this type of seal ring in the market. The preparation process of the sealing ring is basically a local vulcanization technology, and for the convenience of further understanding of the scheme, the preparation method of the sealing ring is simply described.
The vulcanization is a process of converting linear macromolecules into a three-dimensional network structure under certain temperature and pressure conditions. As the name suggests, the vulcanization is performed under certain pressure and temperature conditions. The conventional vulcanizing device (taking a press vulcanizing machine as an example) generally comprises an upper die plate, a lower die plate and a pressurizing oil cylinder, wherein heating pipes (not shown in the figure) are arranged in the upper die plate and the lower die plate, so that the die is heated to meet the vulcanizing temperature condition. A vulcanizer for processing a partially vulcanized seal ring is provided with cooling ducts in the partial locations of an upper die plate and a lower die plate to reduce the temperature of the die at that portion during production. For convenience of description, this partial region of the mold will now be defined as a cooling zone. When the sealing ring with the vulcanization is vulcanized, the part of the sealing ring outside the cooling area can reach the vulcanization temperature (175-180 ℃) so as to normally carry out the vulcanization, and the part of the sealing ring inside the cooling area can not reach the normal vulcanization temperature due to the existence of the cooling pipeline, so that the part of the sealing ring can not be completely vulcanized, but is in a semi-vulcanization state.
Second, the semi-vulcanized area 42 is cut, and the cut is located at the middle position of the semi-vulcanized area 42, so that the sealing ring is in an open-loop state.
As shown in fig. 15, the cuts produced by the cutting include a horizontal cut 421 and first and second vertical cuts 422 and 423 located at both ends of the horizontal cut 421, and the first vertical cut 422 extends upward through the sealing ring, and the second vertical cut 423 extends downward through the sealing ring. Preferably, the horizontal cut 421 is located at a middle position of the seal ring in the thickness direction.
The arc length M of the horizontal cut 421 is smaller than the arc length N of the semi-vulcanized area 42 of the sealing ring. I.e. the horizontal cut 421 is located entirely within the semi-vulcanisation zone 42 of the sealing ring.
Thirdly, the flange at the connecting part of the GIS shell is detached, the GIS shell is moved for a certain distance, the original sealing ring can be taken out, and then the original sealing ring is sheared and taken down.
Fourth, the sealing ring to be installed bypasses the conductor in the GIS shell, is placed at the position to be installed, and the opening of the sealing ring is located outside the GIS shell.
Fifthly, the end parts of the sealing rings are placed between a fixed template and a movable template of the vulcanizing machine, and the end parts of the sealing rings are in lap joint or end face contact, so that a complete ring state is achieved.
Sixthly, starting a vulcanizing machine, maintaining the pressure at 15MPa, the temperature at 175-180 ℃ and the pressure maintaining time at 10-15min, vulcanizing the part of the end part of the sealing ring in a semi-vulcanized state, and thus completing the butt joint of the sealing ring.
Seventhly, adjusting the sealing ring after the butt joint is finished to be positioned at the installation position, and then fastening and installing the flange at the joint of the GIS shell.
