Description

The vulcanizing production uses a tooling for a vulcanizing model, the vulcanizing model consists of an upper die, a lower die, a steel ring and a clamp, the steel ring is divided into an upper steel ring and a lower steel ring, the A-shaped machine clamp consists of a steel ring and a self-contained part of equipment, and the self-contained part of the equipment comprises a clamp plate, a ball nose, a bag barrel and the like; the clamp of the B-type machine consists of a lower steel ring, a positioning disc, an upper chuck and a lower chuck, wherein the tire bead engagement parts of the steel rings of the vulcanization models of the A-type vulcanizing machine and the B-type vulcanizing machine are consistent, but the clamp difference of the capsules is large, the geometric shapes and the structures of the clamp are different, and the two models cannot be used simultaneously under the conventional condition, namely, the vulcanization model of the same tire product can only be applied to the A-type vulcanizing machine or the B-type vulcanizing machine. The interface of the steel ring of the vulcanization model and the upper and lower dies is positioned on the product surface, the interface is called as the product interface of the steel ring, the interface condition directly affects the appearance quality of the tire product, the interface is in taper fit, the parameters of the interface have the requirements of fit clearance and the difference between the surfaces of the two, in the processing, even if the design is a high-requirement small tolerance value, the steel ring also has to be repeatedly tried and matched with the corresponding parts of the upper and lower dies to reach the requirements, namely the vulcanization steel ring has one-to-one correspondence with the upper and lower dies, and the part processing technical requirements are high. The timeliness of the actual tire products is superior to the production timeliness, namely the tire production requirement is fast, the scientificity is emphasized by the tire model storage and coordinated production organization, the productivity of equipment can be exerted to the greatest extent, and the contradiction between the storage quantity and the utilization rate of equipment tools is balanced; the difference in the real market also determines that the reserve of the tire model is difficult to determine, and the production of two vulcanizing machines is shared in the life cycle of the vulcanizing model.
The inventor researches that if the two sets of steel rings which are suitable for the A-type vulcanizing machine and the B-type vulcanizing machine are selected to be produced simultaneously at the beginning of the asset input, each pair of models needs to be provided with two sets of steel rings which are suitable for the A-type vulcanizing machine and the B-type vulcanizing machine, and the storage capacity of the steel ring asset is large and the idle capacity of the asset is also large due to the plurality of models. If the small number of models are used as the models according to market demands, the processing of the vulcanized steel ring needs to be matched with the upper die and the lower die, the delayed production exists in the matched process of the vulcanized die, the processing preparation condition of the supplemented vulcanized steel ring is harsh, and the flexibility is poor. The technical requirement of steel ring processing is high and the flexibility is poor, so that the processing difficulty of the vulcanized steel ring is high.

Detailed Description
The difference in the real market also determines that the reserve of the tire model is difficult to determine, and the production of two vulcanizing machines is shared in the life cycle of the vulcanizing model. If the asset input is considered to be selected on the A-type vulcanizing machine or the B-type vulcanizing machine to be produced simultaneously, two sets of steel rings which are suitable for the A-type vulcanizing machine and the B-type vulcanizing machine are required to be configured for each pair of models, and a plurality of models enable the storage capacity of the steel ring asset to be large and the idle capacity of the asset to be large. If a few models are used as the models according to market demands, the processing difficulty of the vulcanized steel ring is high, and the production delay exists in real-time vehicle matching and supplementing.
