With the improvement of life quality, metal automobile stamping parts have penetrated into various fields. No matter in industrial production or daily life, many places will use various metal stamping parts. It is closely related to our life and cannot be separated. What process and technical requirements are needed in the production of metal stamping parts in the hardware processing factory to produce hardware products that can meet the production and life of consumers?

Fine metal stamping is mainly classified by process, which can be divided into two categories: separation process and forming process. Parting process can also be called blanking, which aims to separate fine stamping parts from sheet metal along a certain contour line and ensure the quality requirements of parting section together.

Automobile stamping parts are processed by punch. In the whole process, the operation of lathe equipment is very critical. If not properly grasped, it will not only affect the forming quality of stamping parts, but also the equipment may be damaged. The key is that the safety of staff can not be guaranteed. Therefore, the operation requirements of lathe equipment for stamping parts processing will be brought to you soon.

If the installation process of automobile stamping parts is classified, stamping is generally divided into two major processes: forming and separation. Each process has its own inspection standard. The goal of forming is to make the sheet material into the required shape and size without breaking the blank. The purpose of the separation process is to separate the stamping parts from the sheet metal according to the established objectives, and at the same time, it is necessary to ensure that the quality of the separation section meets the standard requirements.

The so-called automobile stamping technology refers to the adaptability of stamping parts to handicrafts, that is, whether the designed stamping parts meet the stamping process requirements in size, size accuracy and benchmark, structural shape, etc. Automobile stamping parts should have good handicrafts and economy. The important marks to weigh their level are the number of stamping processes, the number and size of the car body assembly blocks, the structure of stamping parts and other factors.

If the programming program of automobile sheet metal parts has some problems, it will cause irreparable loss. Because the special-shaped part of this kind of door plate is used to install the door stopper, the following processing scheme is usually adopted in mass production of this kind of door plate: cutting by shearing machine (three door stopper pieces are cut separately) → punching by punch machine → cutting angle → folding by folding machine → welding four corners and three door stopper pieces. The improvement of the scheme not only saves the cost of raw materials and equipment maintenance, but also greatly reduces the programming error rate.

It's said that the staff who make Lexus can touch the subtle differences on the body with their hands. It's very difficult for us to reach similar level without professional training, but you don't need to worry too much. After all, as long as a car reaches the factory standard, it's not easy to have defects visible to consumers.

In the cost of automobile stamping parts, the material cost is more than 60%. Therefore, the economic utilization of materials is of great significance. Layout refers to the arrangement and placement of parts on strips or plates. Unreasonable layout will cause material waste. The index to measure the layout economy is the utilization rate of materials. The utility model can reduce the waste area and the material utilization rate is high.

First, observe whether the upper and lower gaps of the front and rear vertical seams of the door are even. If the front of the top seam of the door is small and the rear is large, and the front of the bottom seam is large and the rear is small, it means that the door sinks due to the bending of the plate at the door hinge or fixed plate, which can be corrected.

Generally speaking, we can judge from two aspects: body and surface covering. Next, let's say one by one, but we need to pay attention to one thing. Here's the method you can use as an ordinary car buyer to go to the 4S shop. Because it doesn't involve special tools, it's not professional, but with them you can generally understand the quality of automobile sheet metal parts.

Bending die is made of high-quality steel through special heat treatment, with high hardness, not easy to wear and bear large pressure, but each set of die has its limit pressure: T / m, so when using the die, the length of the die should be selected correctly, that is, how much pressure should be added per meter, and never exceed the pressure marked by the die.

When many users are designing new products or developing products, they usually focus on product development and development at the initial stage, or price, rather than communication and exchange with injection mold manufacturers. In fact, it is necessary to communicate with injection mold manufacturers in advance after determining the preliminary design scheme of products. Today, I will give you a specific introduction of injection molding What should be paid attention to when opening die for auto parts.

The repair methods of automobile sheet metal parts mainly include the following five parts: knock off repair method, pry top repair method, stretching repair method, heating shrinkage method, pleating method, etc.

Auto parts hardware stamping is a very important part of the automobile structure. In medium and heavy-duty vehicles, most of the covering parts, such as the body outer panel, and some load-bearing and supporting parts, such as the frame, carriage and other auto parts are all auto parts hardware stamping parts. So what should be done when selecting materials for this product?

The realization of all kinds of stamping process has its basic motion mechanism, which is closely related to the die. The structural design and mechanical design of all kinds of dies are to meet the requirements of realizing specific motion. Whether the designed die can achieve the required movement of stamping process strictly or not directly affects the quality of automotive stamping parts, so the mechanical movement should be controlled in the die design. At the same time, in order to meet the requirements of the shape and size of products, we should not stick to or be limited to the basic movement mode of various processes, but should continue to develop and innovate, and use the mechanical movement flexibly in the mold design.

Automobile is a big cost product for most families in our country, so everyone should be careful when choosing the right motor vehicle. In fact, there are many scales to choose the time of motor vehicles. However, if we want to get whether the motor vehicles in front of us can meet our own requirements in a simple way, it is also a good way to see the quality of the whole vehicle from the quality of the stamping parts.

The surface of automobile paint repair must be carefully treated before painting. The surface treatment in automobile repair should be treated differently according to the specific situation, generally including cleaning, degreasing and lubricating grease removal, thorough removal of damaged paint film, grinding and derusting as well as post cleaning and other processes.

In the process of producing automobile stamping parts, it is easy to affect the service life of the die and the quality of stamping products because of the raw materials, heat treatment, structure, use specification and maintenance frequency of the die used, so how can we reduce or avoid the occurrence of this matter in the production of automobile stamping parts?

The outstanding advantage of modular stamping is that it can combine the flexibility of stamping system with high efficiency production. Flexibility has a wide meaning, such as the requirements of the geometric shape of stamping parts, which can be obtained only through free programming, reflecting the flexibility of machining shape. For example, it is not only suitable for the production of large-scale single variety stamping parts, but also flexible for the processing of small batch and multi variety.

When designing new products or developing products, many users usually focus on product development and development at the initial stage, or price, rather than communication and exchange with injection mold manufacturers. In fact, it is necessary to communicate with injection mold manufacturers in advance after determining the preliminary design scheme of products. Today, I will give you a specific introduction of steam injection What are the precautions for the opening of the plastic mould for car parts.
