The present invention is generally related to tire curing devices, and more particular to a hydraulic curing system of enhanced convenience in transportation and assembly.
Hydraulic curing is a major process in manufacturing tires. Tires are solidly formed by the high-temperature, high-pressure curing process so that subsequent operations can be conducted.
Existing apparatus for hydraulic curing usually has dual molds or multiple molds for working on multiple tires with a single curing device for increased productivity. As the dimension of tires is increased, the apparatus for hydraulic curing has to be increased in size too.
A manufacturer of the apparatus for hydraulic curing is usually required to ship the apparatus to overseas where the tire manufacturing plant is located.
As the size of the apparatus is increased, the difficulty in transportation and therefore the cost are also increased. For example, the apparatus may not be able to fit in a normal-sized container, may not be lifted by an ordinary crane, etc.
Additionally, when the apparatus arrives at the site, sometimes, some demolishing work to the plant's building has to be done so that the apparatus can be moved inside the plant. Afterwards, the building has to be recovered.
Therefore, to obviate the shortcomings of prior arts, the present invention provides a novel hydraulic curing system of enhanced convenience in transportation and assembly.
A major gist of the present invention lies in its detachable arrangement to a first and second hydraulic curing devices by applying fastener sets to the corresponding first and second joint hole sets on the first and second hydraulic curing devices, thereby achieving the enhanced convenience in transportation and assembly.
The hydraulic curing system contains a firs hydraulic curing device, a second hydraulic curing device, and a number of fastener sets fixedly coupling the first and second hydraulic curing devices side by side together. The first hydraulic curing device has a number of first joint hole sets; whereas the second hydraulic curing device has a number of second joint hole sets. The fastener sets fixedly couple the first and second hydraulic curing devices side by side together by fastening corresponding first and second joint hole sets.
Through the present invention, the transportation and assembly of the hydraulic curing system can be conducted by handling the first and second hydraulic curing devices separately. The convenience of the transportation and assembly is as such significantly enhanced.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become apparent to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
The second hydraulic curing device 2 has a second joint face 22, and a number of second joint hole sets 21 on the second joint face 22. Each second joint hole set 21 contains at least a second positioning hole 211 and a number of second joint holes 212.
The hydraulic curing system further contains a number of fastener sets 3 with which the first and second hydraulic curing devices 1 and 2 are coupled side by side together.
As shown in
The advantage of the hydraulic curing system over prior arts lies in its detachable arrangement to the first and second hydraulic curing devices 1 and 2 by applying fastener sets 3 to the corresponding first and second joint hole sets 11 and 21, thereby achieving the enhanced convenience in transportation and assembly.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
