                  Abstract: This article introduces a combined device that integrates the functions of mold adjustment
              and force measurement mechanisms for mechanical tire shaping and curing presses, enabling simultaneous
              automatic mold adjustment, recording, and display of cold mold clamping force. The device, achieved
              by adding a rotary displacement encoder and upgrading the PLC program, features a simple structure,
              convenient operation, and strong versatility. It offers a low-cost and easy-to-implement solution for the
              intelligent retrofitting of existing curing presses.

                  The tire shaping and curing press is used in the final   curing presses, dual-column manipulator transformation,
              process of tire production, which is an important step in tire   steamer to hot plate transformation, and integrated valve group
              shaping and qualitative determination. It can be said that   application. Song Peifen, combining enterprise management
              the tire shaping and curing press is a key equipment that   concepts, has achieved good results in a series of energy-
              determines the quality of tires. After more than 40 years of   saving improvements for tire curing presses, such as using
              reform and opening up in China, with the great development   PLC control for curing press condensate water discharge,
              of electrical and informatization, tire curing equipment has   which results in a low failure rate and saves 30% to 40% of
              gradually gone through stages of exploration, including curing   steam. Zheng Wanli and others have carried out technical
              tanks, single-unit curing presses, groups of curing presses,   transformation and management improvement based on the
              and pure electric curing presses. In the process of pursuing   inherent safety of the curing process, implementing measures
              innovation in curing presses, countless manufacturers have   such as mandatory inspection of the safety rod of the curing
              proposed improvements such as automation, structural   press and linkage protection of the mold opening and closing
              optimization, energy saving, safety, electric heating, and   electrical system to improve the curing process. Shang Rongwu
              intelligence for single-unit curing presses, based on their   and others have proposed an electromagnetic induction heating
              business and development stages. For example, Luo Yongfeng   device for the segmented mold of the curing press to enhance
              and others have conducted technical automation transformation   the quality and performance of vulcanized tires, analyzing the
              and promotion of the shaping pressure, manipulator, and curing   magnetic flux leakage shielding and electromagnetic heating
              control program of all-steel tire curing presses, which not only   characteristics of the segmented mold.
              ensures production continuity but also improves production   The mold adjustment of a mechanical tire shaping and
              efficiency and curing qualification rate. Guo Lianggang and

              others have discussed upgrades and transformations in aspects   primarily engaged in research and design work related to the electrical
              such as replacing hydraulic power with water for mechanical   aspects of curing presses.
