In fact, there is a lot of knowledge to know about automotive stamping parts. Many problems are beyond your reach at ordinary times. The application of different stamping parts in different industries requires different knowledge points. The following is a brief introduction to stamping.

Generally, we calculate the development size of stamping parts in this way. First of all, we should not consider bending to make the material thinner. The calculation method is very simple. First, calculate the radius R of the neutral layer of the bending part (find out the location coefficient x of the neutral layer, R=r+xt), and then calculate the developed length of the bending section according to the arc length formula. 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, we will introduce the stamping process of automobile body for automobile sheet metal parts:

1. Cut the whole roll of steel plates with a thickness of 1.0mm to 1.2mm, which are special for automobiles, into several pieces of different sizes, and sort them out so that they can be used for different purposes.

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

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

So far, batches of automobile steel plates have become body parts with complex shapes and structures. Then they were sent to the welding workshop for the next process.

What are the effects and hazards of using the steering wheel cover on driving? According to the traffic patrol police, the low temperature in winter will reduce people's responsiveness and perception, and the use of steering wheel covers increases the difficulty for drivers to control.

Secondly, in winter, the road is often icy. The use of the steering wheel cover will reduce the friction between the steering wheel and hands. In the case of slippery roads and sharp turns in rain and snow, the steering wheel is not easy to control, and the control is easy to slip. It is not conducive to safe handling when dealing with emergencies. The steering wheel is easy to release, affecting safety and causing accidents.
