For many people who get a driver's license, some knowledge of the driver's license may still be unclear. For example, what if the driver's license expires? How does the driver's license in the field test go to the household registration? What is the procedure for the replacement of driver's license? In response to these very common issues in Europe, Xiaobian made a summary for everyone today. First: renew driver's license Loss of driver's license will require re-submitting. It may be a problem for many car owners. This is not a bank card. Therefore, it is not necessary to apply for loss reporting. Preparation materials: ID card and photocopy of the client, application for re-applying a driver's license, two small-size photos. Precautions: 1. If the driver’s license is required to be reissued, if there are three months to expire, the driver’s license must be changed at the same time; 2. If the original driver's license is recovered after the issuance of the certificate, the original driver's license should be returned to the issuing authority in a timely manner. Otherwise, the driver's license will be deemed as holding a dual license. The public security and vehicle management department will be cancelled according to the regulations. . Second: Expiration of driver's license This is related to the renewal of the license. The vehicle owners should apply for renewal of the vehicle license at the place where the driver's license is issued within 90 days before the expiry date of the motor vehicle driver’s license. If the vehicle’s driver’s license has exceeded the validity period for more than one year, Log off the motor vehicle driver's license. (I'm going to punish you. I often watch the driver's license. I don't know when it expired and I missed one year and I have to admire you.) It should be noted that the annual review has now been abolished. Basically, the certificates are changed every six years. Of course, for some vehicles, it is another matter. We can look at our driver's licenses for understanding. If the valid period of the motor vehicle driver's license is more than one year without replacement, and if the driver's license is cancelled for more than two years, the normal use of your driver's license may be resumed after passing the examination of subject one; if it is written off for more than two years, a new application is required. Third: The foreign driver's license is transferred to the place of residence In foreign places, the driver's license needs to be transferred to the location of his or her household registration. To understand, there are too many people driving test drives in different places. So we must take a good look at this. condition: 1. The motor vehicle driver’s household registration has moved into the local area or the motor vehicle driver has lived in the local area; 2. Inquire the national public security traffic management information system, compare, confirm the applicant information, and the vehicle driver's license information is true and valid; 3. The motor vehicle driver does not have the circumstances of being revoked, cancelled or cancelled the motor vehicle driver's license according to law; 4. The cumulative score of the motor vehicle driver does not reach full marks (out of 24 points). Required materials: 1. "Application Form for Motor Vehicle Driving Licence" (to apply to the vehicle management bureau that wants to migrate from the past) 2. Identification and photocopy of motor vehicle driver's identity; 3, the original motor vehicle driver's license; 4, an inch, bareheaded, color, white, big head photo. 5, commissioned by the agency should also provide proof of identity and a copy of the agent (I can not personally go, so that others need to go). The cost is about 15-20 yuan. Press Die Components are also called hardware die Components.

1. Wear resistance
When the blank is plastic in the mold cavity, it flows and slides along the surface of the mold cavity, causing severe friction between the surface of the mold cavity and the blank, which leads to the failure of the mold due to wear. So the wear resistance of the material is one of the most basic and important properties of the mold.
Hardness is the main factor affecting the wear resistance. Generally, the higher the hardness of die parts, the smaller the wear amount and the better the wear resistance. In addition, the wear resistance is also related to the type, quantity, shape, size and distribution of carbide in the material.
2. Strong toughness
Most of the working conditions of dies are very bad, some of them often bear large impact load, which leads to brittle fracture. In order to prevent the die parts from brittle fracture, the die should have high strength and toughness. The toughness of die mainly depends on carbon content, grain size and microstructure.
3. Fatigue fracture properties
In the process of die working, under the long-term action of cyclic stress, it often leads to fatigue fracture. Its forms are small energy multiple impact fatigue fracture, tensile fatigue fracture contact fatigue fracture and bending fatigue fracture. The fatigue fracture performance of the die mainly depends on its strength, toughness, hardness and the content of inclusions in the material.
4. High temperature performance
When the working temperature of the die is high, the hardness and strength will decrease, which will lead to early wear or plastic deformation of the die and failure. Therefore, the die material should have high tempering stability to ensure that the die has high hardness and strength at working temperature.
5. Cold and hot fatigue resistance
Some dies are in the state of repeated heating and cooling in the working process, which makes the surface of the cavity subject to tensile and pressure stress, causes surface cracking and peeling, increases friction, hinders plastic deformation, reduces dimensional accuracy, and leads to die failure. Cold and hot fatigue is one of the main failure modes of hot working dies, which should have high cold and hot fatigue resistance.
6. Corrosion resistance
Some molds, such as plastic molds, because of the presence of chlorine, fluorine and other elements in the plastic, decompose and precipitate strong corrosive gases such as HCI and HF after being heated, which erode the surface of mold cavity, increase its surface roughness, and intensify wear failure.
The materials of Die accessories are usually tungsten steel, high speed steel, bearing steel, stainless steel, brass, metal alloy, spring steel, carbonized steel, etc.
