The second fixing template 32 is fixedly connected with the front side surface of the C-shaped frame body. The rear side of the C-shaped frame body is provided with a first connecting plate 34, the left side and the right side of the C-shaped frame body are respectively provided with a guide rod capable of sliding back and forth relative to the C-shaped frame body, the front end of the guide rod is fixedly connected with the second movable template 31, and the rear end of the guide rod is fixedly connected with the first connecting plate 34. And a sliding seat 16 matched with the guide rod is arranged on the C-shaped frame body.
A second oil cylinder 33 is arranged between the first connecting plate 34 and the C-shaped frame body, a piston rod of the second oil cylinder 33 is fixedly connected with the first connecting plate 34, and a cylinder body of the second oil cylinder 33 is fixedly connected with the C-shaped frame body.
Heating pipes are arranged in the first movable die plate 21, the second movable die plate 31, the first fixed die plate 22 and the second fixed die plate 32.
Further, in order to reduce the volume of the whole equipment and facilitate the field operation, as shown in fig. 1 and 2, the C-shaped frame comprises a bottom plate 11, and two C-shaped plates 12 with openings facing to 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 fixing template 22 and the second fixing template 32 are fixedly connected to the C-shaped plate 12. As a specific embodiment, in this embodiment, a first boss 221 and a second boss 321 extending inward are respectively disposed on inner side surfaces (taking a side close to the C-shaped frame body as an inner side) of the first fixing template 22 and the second fixing template 32, and a dimension of the first boss 221 and the second boss 321 in the left-right direction is equal to a distance between the two C-shaped plates 12. The left and right ends of the first boss 221 and the second boss 321 are respectively fixedly connected with the C-shaped plate 12 through first screws, and holes for accommodating the first screws on the C-shaped plate 12 are countersunk holes.
As shown in fig. 4, 6 and 9, the first oil cylinder 23 and the second oil cylinder 33 are both located between the two C-shaped plates 12. The outer side surfaces of the C-shaped plates 12 (the opposite side of the two C-shaped plates 12 is the inner side) are respectively provided with a connecting ear plate 13, and a rib plate 14 is arranged between the connecting ear plates 13 and the C-shaped plates 12. And the left end and the right end of the end connecting plate of the cylinder body of the first oil cylinder 23 are respectively fixedly connected with the connecting lug plate 13 through second screws. Preferably, a certain distance M is provided between the lower side of the connecting ear plate 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. And the left end and the right end of the end connecting plate of the cylinder body of the second oil cylinder 33 are respectively fixedly connected with the rear end surface of the C-shaped plate 12 through third screws.
Therefore, the oil cylinder can be used for realizing the function of reinforcing the frame body, namely, the oil cylinder not only plays a functional role, but also plays a role of a reinforcing component.
Furthermore, 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 the four guide rods are arranged in a matrix of two rows and two columns. For convenience of description, the guide bar located at the upper side is defined as an upper guide bar 36, and the guide bar located at the lower side is defined as a lower guide bar 37. However, although the stability can be increased, since the seal ring after the abutment is in the closed-loop state, the seal ring can be inserted only between the second movable die plate 31 and the second fixed die plate 32 through the gap between the adjacent two guide rods in order to remove the seal ring which is finally in the closed-loop state. Thus, the sealing ring with a larger diameter has the problem of deformation, and the final processing quality is influenced.
For this, as shown in fig. 10 and 11, the through holes of the second moving plate 31 and the first connection plate 34 for receiving the upper guide 36 have the same diameter as that of the upper guide 36. A detachable spacer 38 is disposed on the upper guide bar 36 at the front side of the second movable platen 31, and the spacer 38 determines the limit position of the forward movement of the second movable platen 31 relative to the upper guide bar 36.
As a specific embodiment, flat openings 361 are symmetrically formed on the upper guide bar 36 in the front side of the second movable platen 31 in this embodiment, as shown in fig. 7 and 13, the length of the block 38 is the same as the size of the flat openings 361 in the front-back direction, and a notch 381 penetrating through the block 38 in the length direction is formed in the block 38. The notch 381 comprises two clamping planes 3811, and the distance between the two clamping planes 3811 is equal to the distance between the two flat openings 361. Preferably, the surface connecting the two clamping planes 3811 is an arc-shaped surface 3812, and has the same diameter as the upper guide rod 36.
A second connecting plate 35 is arranged at the rear side of the first connecting plate 34, 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, after the end of the seal ring is inserted into the gap between the upper guide rod 36 and the lower guide rod 37 at the beginning, and the spacer 38 is removed from the upper guide rod 36 after the butt joint is completed to form a closed loop, the upper guide rod 36 can be separated from the second movable mold plate 31 after the spacer 38 is removed from the upper guide rod 36 because the diameter of the upper guide rod 36 is equal to the diameter of the through hole of the second movable mold plate 31 for accommodating 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 movable die plate 31, and the seal 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 form an L-shaped structure together.
Further, as shown in fig. 6 and 9, a supporting plate 15 for supporting the second oil cylinder 33 is arranged between the two C-shaped plates 12, and an arc-shaped groove matched with the outer diameter of the second oil cylinder 33 is formed in the supporting plate 15.
The operation method for replacing the sealing ring by using the vulcanizing machine comprises the following steps:
first, a seal ring of matching dimensions is selected and includes a fully cured zone 41 and a semi-cured zone 42.
Preferably, the ratio of the arc length N of the semi-vulcanization zone 42 to the perimeter L of the sealing ring is 1/10-1/8.
Here, the seal ring including the completely vulcanized part 41 and the semi-vulcanized part means that a part of the seal ring shown in fig. 16 is in a completely vulcanized state, a part of the seal ring is in a semi-vulcanized state, and a part of the seal ring in a semi-vulcanized state is continuous.
The sealing ring comprising the fully vulcanized zone 41 and the semi-vulcanized zone 42 belongs to the prior art in terms of the preparation process, i.e. the sealing ring with partial vulcanization can be prepared by adopting the prior art. At present, manufacturers can customize the type of sealing ring on the market. The preparation process of the sealing ring fundamentally adopts the technology of partial vulcanization, and the preparation method of the sealing ring is simply described at present in order to further understand the scheme.
The sulfuration is a process of converting linear macromolecules into a three-dimensional network structure under certain temperature and pressure conditions. As the name implies, vulcanization is carried out in such a way that certain pressure conditions and temperature conditions are met. The existing vulcanizing equipment (taking a flat vulcanizing machine as an example) generally comprises an upper template, a lower template and a pressurizing oil cylinder, wherein heating pipes (not shown in the figure) are arranged in the upper template and the lower template, so that a mold is heated to meet the vulcanizing temperature condition. A vulcanizer for processing locally vulcanized sealing washer is provided with cooling tube in the local position of cope match-plate pattern and lower bolster to reduce the temperature of mould in this part in the production process. For convenience of description, the partial region of the mold is now defined as a cooling zone. Thus, when the vulcanized sealing ring is vulcanized, the sealing ring outside the cooling zone can reach the vulcanization temperature (175 ℃ -180 ℃) so as to be vulcanized normally, and the sealing ring inside the cooling zone can not reach the normal vulcanization temperature due to the existence of the cooling pipeline, so that the sealing ring of the part is not vulcanized completely but is in a semi-vulcanized state.
Secondly, the semi-vulcanization zone 42 is cut, and the cut is positioned in the middle of the semi-vulcanization zone 42, so that the sealing ring is in an open-loop state.
As shown in fig. 17, the cuts generated by cutting include a horizontal cut 421, and a first vertical cut 422 and a second vertical cut 423 which are located at two ends of the horizontal cut 421, wherein the first vertical cut 422 extends upward to penetrate through the gasket, and the second vertical cut 423 extends downward to penetrate through the gasket. Preferably, the horizontal cut 421 is located at the middle position of the sealing ring along the thickness direction.
The arc length M of the horizontal cut 421 is smaller than the arc length N of the semi-vulcanization zone 42 of the sealing ring. I.e. the horizontal cuts 421 are located entirely within the semi-vulcanization zone 42 of the sealing ring.
Thirdly, the flange at the joint of the GIS shell is disassembled, the GIS shell is moved for a certain distance, the original sealing ring can be taken out, and then the original sealing ring is cut off and taken down.
Fourthly, the sealing ring to be installed bypasses a conductor in the GIS shell and 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 all placed between the fixed die plate and the movable die plate of the vulcanizing machine, and the end parts of the sealing rings are in lap joint or end surface contact to form a complete circular ring state.
And sixthly, starting the vulcanizing machine, maintaining the pressure at 15MPa, the temperature at 175-180 ℃, and the pressure maintaining time at 10-15min, and vulcanizing the part in the semi-vulcanized state at the end part of the sealing ring, thereby completing the butt joint of the sealing ring.
And seventhly, adjusting the butted sealing ring to enable the sealing ring to be located at the installation position, and then fastening and installing the flange at the connection part of the GIS shell.
