The Quality Problem of Leaf Spring of Agricultural Transporter

The agricultural vehicle leaf spring assembly is one of the five major components. The reasons for the product's unqualified product are as follows: 1. The main reasons for the unsatisfactory quality of the free-radical project: 1. The size deviation of the material exceeds the standard, the thickness and width are not uniform or exceeds the difference (thickness and rigidity become the quadratic relationship, and the width and stiffness are linearly related). Therefore, the dimensional deviation of the material has a great influence on the stiffness and should be given enough attention. 2. The arc of the single-plate spring does not meet the design requirements. If the clamp is improperly adjusted during thermoforming, the contact state of each leaf spring is poor, and the deformation is uneven during loading, resulting in instability of the stiffness value. 3. Some companies do not know how to determine the stiffness of the leaf spring, or have not verified the calculated value indicators, so many in mind that the reported parameters or the parameters given on the drawings are inconsistent with the actual situation. Countermeasures 1. Strengthen the inspection of incoming raw materials and strictly control the purchase of raw materials. 2. Strict process requirements and process discipline. 3. Verify the product and correct the technical documents if they do not meet the requirements. Second, the major reasons for the failure of static arc high 1. Raw material size deviation is too large, causing a large deviation in stiffness. 2. The free arc height is incorrect. Countermeasures 1. Put raw materials into storage. 2. Determine the arc height of the single leaf spring and carefully perform the process. Third, the main reason for the failure of fatigue life 1. The quality of the raw material itself. If the leaf spring steel plate modified from the old guideway steel is selected, the material itself has fatigue damage, so it will definitely affect the fatigue life, and because the chemical composition of the material is unstable, the hardness and metallographic structure of the leaf spring do not meet the requirements after the heat treatment. , affecting life expectancy. 2. The material has microscopic defects, such as surface micro cracks, interlayers and other defects. The use of old rail steel remanufactured leaf spring steel plate is more obvious. 3. Improper heat treatment can cause the surface hardness to be too high or too low, affect the strength or toughness of the leaf spring, can also cause the metallurgical structure does not meet the requirements, the surface decarburization is too deep, and the grain is coarse, resulting in spherical graphite, grain boundary With ferrite structure, the grain boundary strength is reduced.

Flower Tea

 

GanoHerb has now developed a new Flower Tea line to help you prepare for hot summer. The ingredients we used for the flower tea products are 100% natural with no additive whatsoever. For example, for the lemon tea, we used pure freshly dried lemon slices in order to maximize the fresh lemon flavor as well as to keep the nutrition inside. Besides that, we also have rose tea, goji berry tea, hawthorn tea, chrysanthemum tea etc. All of them are delicious and easy to make. Simply put the content into a teapot and add boiling water. Within minutes, a pot of delicious flower tea will be ready for you. If you use a transparent glass teapot, you can enjoy watching the flower booming in water. You can also mix some of them together to create your own unique flower tea.

Flower Tea


There are plenty of health benefits you can get from drinking flower tea. They are all very good source of antioxidant, therefore they can prevent cell damage from free radicals. Also, each flower tea has its unique function. For example, rose tea is good for your skin, and chrysanthemum is a effective anti-inflammatory agent and immunity booster, goji berries, on the other hand, help regulate blood sugar and testosterone. Go ahead and make yourself some fresh flower tea, which will not only give you a fresh and delicious taste, but also bring you great health benefits.
