With the increasing number of car ownership, it is becoming more and more common to own a car. Auto parts will always suffer from various wear and tear during use, and maintenance and maintenance are required at this time. For many car owners, car maintenance is nothing more than simple car cleaning and regular inspections to see if there are major problems. But in fact, car maintenance is much more than that. What's more, frequent mistakes in car maintenance, the result not only does not prolong the life of the car, but accelerates the aging of the car, why is this so? It depends on whether the following maintenance misunderstandings occur during maintenance!

With the advancement of science and technology in modern times, manufacturers pay more and more attention to the meticulous processing of sheet metal. Laser cutting technology is one of the methods of sheet metal processing. Sheet metal processing using laser cutting can meet the requirements of narrow slits, smooth and beautiful cutting surfaces, no dross, and high precision for metal processing according to the drawings given by customers.

Practice has proved that in the mass production of medium-thick plate parts with a material thickness of t>3mm and thick plate parts with a thickness of t>4.75mm, the popularization and application of fine blanking technology instead of cutting processing can not only achieve good economic benefits, but also eliminate the current There are occasional personal injury accidents in ordinary stamping production, which can reduce the pollution of stamping noise to the environment and obtain satisfactory occupational safety and environmental protection benefits. These plate parts are difficult to complete with other processing methods. Even if the combination of various types of work is used for cutting and processing, not only the efficiency is low, the quality is difficult to guarantee, but also the cost is very high. The analysis shows the following characteristics:

Any defects on the surface of automobile body stamping parts will affect the beauty of the product, so defects on the surface of automobile stamping parts are not allowed. Automotive stampings require clear and smooth decorative ridges, uniform transitions and symmetry between left and right, and the connection of ridges between stampings outside the car body must be smooth. Stamping parts not only need to meet the structural and functional requirements, but also must meet the requirements of surface quality.

Precision metal stamping parts processing: with the characteristics of thinness, uniformity, lightness and strength. Stamping can produce stamping parts with ribs, ribs, undulations or flanging that are difficult to manufacture by other methods, so as to improve its rigidity. Due to the selection of fine molds, the precision of the workpiece can reach the level of 0.01mm, and the repeatability is high, and the standard is consistent, and it is possible to punch out holes, bosses, etc.

In the stamping of automobile stamping parts, the factors that affect the yield of stamping and drawing generally include the precision of stamping equipment, the rationality of die design, the quality of stamping dies, and the performance of stamping oil. How to choose stamping oil is also a part of stamping technology. An important topic:

Hardware and automotive stamping parts are becoming more and more sophisticated, with more and more varieties, and the market scale is expanding. Due to the increasingly high requirements for quality and precision in various industries, how to ensure quality has become a key factor. There are many reasons for poor stamping parts. Unloading may also damage stamping parts. Therefore, details should be fully considered in every link of the entire manufacturing process to avoid quality problems as much as possible.

At present, many products we manufacture have molds, and then use molds to make them, which can improve production efficiency. Many friends also consulted about the selection principles of automotive stamping dies?

Precision metal stamping parts are ubiquitous in our lives. There are many processes in the production of metal stamping parts, but the hardness of precision metal stamping parts is very important. How do we test it? Shenzhen Chengruifeng The editor of metal stamping will give you a brief introduction.

Any defects on the surface of automobile body stamping parts will affect the beauty of the product, so the surface of automobile stamping parts is not allowed to have defects. Automotive stampings require clear and smooth decorative ridges, uniform transitions and symmetry between left and right, and the connection of ridges between stampings outside the car body must be smooth. Stamping parts not only need to meet the structural and functional requirements, but also must meet the requirements of surface quality.

The stamping process is one of the processing methods to complete metal plastic forming. Usually, the press and the mold apply external force to the sheet, strip, pipe and profile to cause plastic deformation or separation, so as to obtain the desired shape and size of the workpiece.

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 inspection standards. The goal of forming is to make the sheet into the desired shape and size without breaking the billet. The purpose of the separation process is to separate the stamping parts from the sheet according to the established goals, and at the same time, it must ensure that the quality of the separation section meets the standard requirements.

Automotive stamping parts indicate that since stamping parts have developed into large-scale and complex parts, the quality requirements for stamping parts have become more and more stringent. In order to achieve these goals, automobile stamping parts manufacturers have proposed relevant quality control principles, which are reflected in precision. , precision, and sophistication.

In the industrial field, different production processes will have a great impact on the performance of the product. So, for the processing of stainless steel stamping parts, what are its processing characteristics and what are its advantages? Next, automobile stamping parts manufacturers will analyze and answer this question, hoping to help everyone.

Automotive stamping parts are a very critical component that plays an important role in the entire car, but many users are wondering how to buy such auto parts? What kind of automotive stamping parts is suitable?

First of all, the designed automotive stamping parts must be conducive to improving the utilization rate of metal materials, reducing the variety and specifications of materials, and reducing the consumption of materials as much as possible. If allowed, stamping parts can be made of low-cost materials, and the parts can be punched with no waste and less waste as much as possible.

In recent years, with the improvement of people's living standards, the demand for automobiles has also increased. The competition among various automobile factories has become increasingly fierce, and new models with cost competitiveness have been continuously invested to seize the market. Natural resources such as iron ore and coke are increasingly scarce. Improving the utilization rate of materials can not only reduce the manufacturing cost of automobiles and improve the competitiveness of automobile brands, but also conform to the environmental protection concept of energy saving and consumption reduction.

The material of the main working parts of the mold is faulty. Poor material performance and wear resistance; The mold steel is unrefined and has a large number of smelting defects; The forging process of the convex and concave die and the forging blank is not perfect, and there are still hidden dangers of heat treatment.

Stamping parts are often used in daily life, and a large number of products such as instruments, household appliances, bicycles, office machinery, household utensils, etc. are stamping parts. How to reasonably formulate the stamping process?

Touch test: wipe the surface of the outer cover with clean gauze. The inspector needs to wear touch gloves to touch along the longitudinal direction of the automobile stamping parts and close to the surface of the stamping parts. This inspection method depends on the inspector's experience. If necessary, polish the detected suspicious area with an oilstone and verify it, but this method is an effective and rapid inspection method.
