Description

Technical Field

[0001] The utility model relates to the technical field related to sealing ring processing, in particular to a sealing ring vulcanization bonding tool. Background Art

[0002] When large-sized sealing rings were first put into use, they were fully prepared in the finished product production factory and sent to large-sized sealing ring demand manufacturers or construction sites for use. With the increase in applications and the improvement of market requirements, the technology and method of shipping large-sized sealing rings to the site in an open manner and using structural adhesives for bonding during installation has emerged. Sealing rings bonded with structural adhesives can meet the needs of some working conditions, but their strength, medium applicability, etc. are significantly different from those of sealing rings bonded with vulcanization. In order to meet market demand, a method of transporting vulcanization equipment to the installation site for vulcanization bonding has emerged.

[0003] The current on-site bonding solution mainly uses structural adhesives for bonding and transports vulcanization equipment to the site for vulcanization bonding.

[0004] Structural adhesive for bonding:

[0005] 1. Trim the two ends of the large-sized sealing ring to be bonded to complementary shapes;

[0006] 2. Clean the end faces of the large-sized sealing ring to be bonded;

[0007] 3. Apply structural adhesive to both ends of the large-sized sealing ring to be bonded;

[0008] 4. Apply structural adhesive to the large-sized sealing ring of the opening, align the two ends, and press them together for bonding;

[0009] 5. After the bonding surface has been pressed and cured for a certain period of time, perform appearance inspection and polishing;

[0010] 6. The product is inspected and ready for use.

[0011] The vulcanization equipment is transported to the site for vulcanization bonding:

[0012] 1. Preparation at the bonding site: vulcanization equipment, molds, large-sized sealing rings to be bonded, rubber materials, and operating tools;

[0013] 2. Install the mold on the vulcanization equipment and set the process (vulcanization temperature, vulcanization pressure, vulcanization time) according to the standard vulcanization process;

[0014] 3. After the mold is heated up, place the large-sized sealing ring to be vulcanized and bonded on the mold for vulcanization and bonding according to the vulcanization process;

[0015] 4. After the sealing ring is vulcanized and bonded, it is taken out, cooled, and flash treatment is performed;

[0016] 5. Inspect the product and keep it ready for use after it passes the inspection.

[0017] 6. On-site cleaning (equipment, molds, materials, tools, etc. are returned to the appropriate area)

[0018] In summary, the shortcomings of the prior art are:

[0019] The strength of structural adhesive bonding is significantly weaker than that of vulcanized bonding. At the same time, structural adhesive cannot adapt to many working media (such as water, temperatures above 80 degrees, and some alkaline media), so structural adhesive can only be used in some working conditions.

[0020] A vulcanizing equipment weighs more than 10 tons. It is very inconvenient and uneconomical to transport it to the installation site for vulcanization and bonding. It also places very high demands on the work site and supporting facilities.

[0021] In view of the above-mentioned defects, the designers actively carried out research and innovation in order to create a sealing ring vulcanization bonding tooling to make it more valuable for industrial use. Utility Model Content

[0023] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0025] An upper plate sealing cavity distributed along the left-right direction is provided at the bottom middle position of the upper plate, and a pressing plate sealing cavity distributed along the left-right direction is provided at the bottom middle position of the pressing plate, and the cross-sectional structures of the upper plate sealing cavity and the pressing plate sealing cavity are the same;

[0026] A lower plate sealing cavity distributed along the left-right direction is arranged on the lower plate directly below the upper plate sealing cavity and the pressure plate sealing cavity.

[0027] As a further improvement of the utility model, a plurality of guide posts are evenly distributed on the bottom of the upper plate and the pressure plate, and guide holes matching the guide posts are provided on the lower plate directly below the guide posts, and the guide posts can be embedded in the guide holes below from top to bottom.
