Bilateral shear crankshaft dry oil lubrication method, device and equipment and computer readable storage medium

Abstract

The invention provides a bilateral shear crankshaft dry oil lubrication method. The bilateral shear crankshaft dry oil lubrication method comprises the steps that the internal temperature and the surface temperature of a crankshaft are collected; an arithmetic mean value of the internal temperature of the crankshaft and the surface temperature of the crankshaft is calculated; a temperature deviation and a temperature deviation change rate are obtained according to the arithmetic mean value and a set temperature; the temperature deviation and the temperature deviation change rate are subjected to fuzzification to obtain the fuzzy quantity of the temperature deviation and the fuzzy quantity of the temperature deviation change rate; fuzzy reasoning is carried out on the fuzzy quantity of the temperature deviation and the fuzzy quantity EC of the temperature deviation change rate to obtain a fuzzy output quantity; the number of times that bilateral shears finish shearing within a period of time is counted; and when the shearing frequency is greater than or equal to the fuzzy output quantity, one-time refueling action on the crankshaft is finished. According to the bilateral shear crankshaft dry oil lubrication method and device, the structure is simple, detection is reliable, the safety coefficient of the bilateral shear crankshaft is improved, and the labor intensity of crankshaft temperature measurement in the production process of the bilateral shears is reduced.

Description

[0001] This application is a divisional application of 2019101738773, the original application filing date: March 8, 2019, the application number: 2019101738773, the name of the invention: double-sided shear crankshaft temperature detection method, device, dry oil lubrication method and device technical field [0002] The invention relates to a lubricating method, in particular to a dry oil lubricating method, device, equipment and a computer-readable storage medium for double-shear crankshafts. Background technique [0003] The double-sided shear is an important processing equipment in the finishing process of the medium and thick plate production line, and the crankshaft is an important part of the double-sided shear. The quality of its lubrication is directly related to the normal operation of the double-sided shear. The crankshaft copper sleeve is lubricated with dry oil. When the oil supply is too small, the crankshaft will stop shearing due to poor lubrication and the t...

AI Technical Summary

Problems solved by technology

The crankshaft copper sleeve is lubricated with dry oil. When the oil supply is too small, the crankshaft will stop shearing due to poor lubrication and the temperature is too high. When the oil supply is too much, the crankshaft is well lubricated, but too much dry oil overflow will cause oil stains on the steel plate and affect the steel plate. Surface quality, excessive oil pollution not only wastes dry oil and pollutes the environment, but also increases the labor intensity of workers and pushes up production costs

At present, the double-shear crankshaft is lubricated at a fixed period, and the dry oil lubrication system is often in an over-lubricated state
