A method for measuring the amount of carcass twitch in each process of tire manufacturing process

Abstract

The invention discloses a method for measuring the amount of carcass pumping in each process of the tire manufacturing process, which specifically includes the following steps: obtaining tire samples at different stages in each process of the tire manufacturing process; dividing and marking the carcass of the tire sample in the circumferential direction of the building drum n measuring points, obtain a sample of the traveler composite part, and make a marking line along the circumference of the outer edge of the traveler composite part; measure the distance from the end points of the carcass on both sides of the forming drum to the center point of the forming drum according to the position of the measuring point in different process stages And calculate the average value; then obtain the tire sample and fit it on the building drum, mark m measuring points in the circumferential direction of the building drum, cut the formed tire blank at any two adjacent measuring points to obtain m sections, and obtain the results of each process stage Carcass pumping and calculating the sum of carcass pumping in the tire manufacturing process. The invention can determine the problematic process in the manufacturing process and take countermeasures through the calculation of the carcass pumping amount in different processes, reduce the difference in tire quality, and improve the manufacturing accuracy.

Description

Technical field [0001] The present invention relates to a tire manufacturing technology, in particular it relates to a measuring method in each step tic amount of one carcass tire manufacturing process. Background technique [0002] Experience in the tire manufacturing process of the tire toward the central direction tics, such as a molding machine and a pneumatic tire billet drum pressure during the tire carcass because of the pressure lumen that tension tic center direction toward the tire. For each step of the carcass MOVEMENT AMOUNT manufacturing processes, without prior measurement method. [0003] In the tire manufacturing process at the same production machine there are fluctuations in the amount of tic tire carcass, the carcass tics finished tire carcass can cause excessive bending shoulder line and shoulders dilute symptom of a disease. When an amount of greater volatility tic carcass, often by a width adjusting machine plane, shoulder drum shaped like parameters to adju...

AI Technical Summary

Problems solved by technology

When the amount of carcass twitching fluctuates greatly, it is often necessary to adjust the length of the carcass between the two bead rings by adjusting the molding parameters such as the plane width and drum shoulder width of the molding machine for temporary countermeasures. The quantity is unknown, it is impossible to determine the problematic process in the manufacturing process, and it is impossible to find the real cause to prevent the problem from reoccurring

There are large differences in the tooling parameters of the molding machines purchased by tire companies from different manufacturers and at different times. For example, the size of the sector block of the locking traveler is different, which will directly cause the difference in the amount of carcass twitch produced by different molding machines. The same product in different The quality of molding machine production is different

[0004] The disadvantage of the prior art is that in the process of making tires for different types of molding machines, the twitching amount of the carcass in each process cannot be determined
