In fact, there are a lot of knowledge to know about automotive stamping parts, many problems are usually out of your reach. When you apply different stamping parts in different industries, you need to know different knowledge points. Next, stamping is a simple way for you to understand.

Generally, we calculate the development dimension of stamping parts in this way. First of all, let's not think about bending to make the material thinner at all. The calculation method is very simple. It is mainly to find out the radius r of the neutral layer of the bending part (find out the position coefficient X of the neutral layer, r = R + XT), and then calculate the expansion length of the bending section according to the arc length formula. Just sum. If you want to consider the material thinning of the bending part, you need to calculate the blank according to the principle of constant volume, which needs further correction.

Today's automobile sheet metal parts introduce the stamping process of automobile body:

1. Cut the whole roll of steel plate with thickness between 1.0mm and 1.2mm into several pieces of different sizes, and then sort them to have different uses.

2. Steel of different sizes shall go through a process of edge cutting. Then it is assigned to each press for the next step. The flat steel is reshaped by the press and pressed into various stamping parts on the body.

3. The pressed front fender shall be placed neatly in the finished product area for use. Press formed vehicle side body.

So far, a batch of automobile steel plates have become the body parts with complex shape and structure. Then they were sent to the welding workshop and entered the next process.

What are the effects and hazards of using the steering wheel cover on driving? According to the traffic police, when the temperature is low in winter, people's reaction ability and perception ability will decline. Using the steering wheel cover increases the difficulty of the driver's operation.

Secondly, in rainy and snowy weather in winter, the road is often frozen. Using the steering wheel cover will reduce the friction between the steering wheel and the hand. When encountering slippery and sharp turning road conditions, the steering wheel is not easy to control, and easy to slide the handle. It is not conducive to safety disposal when dealing with emergency situations. The steering wheel is easy to get out of hand, affecting safety and causing accidents.
