introduction: The causes of mold cracks are: 1、Insufficient mold rigidity 2、The stress concentration of the corner of the cavity Mold wall thickness design is an important parameter of mold design,Perform strength calculation(Simple tension simple calculation),To ensure the necessary thickness of the mold.In addition,Additional grooves to take advantage of the overall rigidity of the mold. It is easy to produce stress concentration when machining the corners of the die cavity,Cracks are also prone to occur here,So the corner must be processed into a circular cornerRThe shape of solution:The corners of the mold cavity are processed into rounded cornersRthe

introduction:The hydraulic oil temperature of the electric forklift is too high When the forklift hydraulic oil temperature reaches80℃The above,The coefficient of thermal expansion of hydraulic components is different,The gap between the relative moving elements and the operating state will change abnormally。Gap widening,The oil leak is getting worse;Gap reduction,May occur between components“stick”phenomenon,Make it impossible to move,It will also cause thermal deformation of the machine,Destroy the original accuracy。 In the summer, the working temperature of the hydraulic oil of the electric forklift truck is too high. In the recent period of time, many users have received feedback,This is a common phenomenon of electric forklifts,Also normal

introduction:It is becoming increasingly important to check the status of in-operation transfers and prepare a thorough inspection plan in advance。Which again with bearings[bearing:bearing(“Bearing”,Japanese person“Axial receptor”)It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said,When other parts move relative to each other on the shaft,A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Be the center of attention,Because its the most important rotating part of any turnaround,Condition monitoring is an important part of preventive maintenance。Early detection of bearing damage to avoid damage caused by bearing damage
