Production precautions and processing procedures for precision stamping parts

In order to produce qualified stamped parts, there are generally the following points that need to be noted in production:

1、 It is necessary to regularly inspect the performance of the punch press, as well as the parallelism and perpendicularity of the slider and worktable.

2、 Strict installation requirements are required for the production of stamping molds. If the stamping factory does not have the ability to produce molds, it is necessary to find a more formal mold factory. The quality of stamping molds determines the quality of stamped parts. Stamping parts should not be sold to unregulated mold factories just to save money.

3、 Before installing the mold, it is necessary to strictly inspect whether the inside of the mold and the punching table are clean, and check the lubrication of the mold guide column.

4、 During the production process, it is necessary to regularly inspect and replace springs to avoid any problems that may affect the quality of stamped parts.

5、 Stamping workers must strictly follow the established rules and regulations when installing stamping molds.

6、 In the actual production process, if there is wear on the cutting edge of the mold, it should be repaired or replaced in a timely manner, otherwise it will cause the damage to the mold to continue to increase.

Metal stamping parts; The fundamental quality lies in the stamping die, only the stamping die can produce qualified metal stamping parts. 80% of the quality problems with stamped parts are caused by stamping molds. So, designing and producing stamping molds is very important. The general requirements for stamping molds are as follows:

1、 Ability to produce stamping

The production of automotive hardware stamping parts has always been a top priority for industrial production enterprises, and stamping enterprises are even more so. In recent years, frequent stamping accidents have caused many stamping factories to encounter difficulties in recruiting workers. A large part of these stamping accidents are caused by unreasonable mold design. So, the stamping mold first needs to have the capability of stamping production. Only when the productivity is met can the next step of work be carried out.

2、 Can improve product production efficiency

Many mold factories often only consider producing qualified stamped parts when designing molds, ignoring the convenience of stamping workers in operation. Resulting in the inability of actual stamping production workers to achieve productivity. Nowadays, stamping enterprises are fiercely competitive, and only by improving stamping efficiency can production costs be significantly reduced.

3、 Can improve product quality

In the past decade or so of working in stamping, I have encountered too many stamping peers and created new molds that work well at first, but after using them for a long time, I am unable to produce qualified stamping parts. In practical use, stamping molds for automotive parts have to withstand considerable impact forces. If the mold design and production are reasonable, problems such as deformation and wear are very likely to occur. The quality of the product cannot be produced.

As long as the stamping process is reasonable, it can reduce defects and waste in the practical production process, and also increase the output value of the product. Outstanding stamping molds for metal stamping parts rely on stamping molds for direct processing and production, so the quality of the molds is crucial, especially for mass-produced metal stamping parts. The unevenness of the mold quality greatly affects the cost of metal stamping parts.

In addition to metal stamping parts, efforts should also be made to minimize the production process of the product under reasonable circumstances. Nowadays, the cost of using automated production for metal stamping parts, especially for electronic stamping parts with relatively small components, is often higher due to manual labor costs. So promoting stamping automation is an inevitable trend.

Try to use continuous stamping molds to promote stamping automation. However, even if manual stamping is used, for some products, it is still necessary to consider using simple continuous molds. Reasonable use of materials for products with low requirements, able to fully utilize scraps for production.

The methods for handling the distortion of metal stamping parts and the burrs caused by stamping during cutting. Training is required for punching cutting edges, and attention should be paid to checking whether the punching gap is reasonable. During the punching process, there has been flipping and distortion deformation of the punched parts, resulting in poor forming after bending. It is necessary to start processing from the punching and cutting station.

Caused by the instability of stamped parts during bending. For U-shaped and V-shaped bending. The key to handling this issue is to guide the stamped parts before bending, guide them during the bending process, and press down on the data during the bending process to prevent slippage of the stamped parts during bending.

We now have some understanding of the methods for handling material distortion in metal stamping parts. The reason for the occurrence of material flipping and distortion in stamped parts is still due to the influence of punching force and unreasonable and uneven punching gaps. Through the above methods, these problems can be effectively addressed to prevent stamped parts from flipping and distorting.

The planned stamping parts have a simple shape and reasonable structure, which is conducive to simplifying the mold structure and reducing the number of processes. This means that the entire part can be processed with fewer and simpler stamping processes, reducing the need for other methods of processing. It is also conducive to stamping operations, facilitating the arrangement of mechanized and automated production, and improving labor productivity.

The planned stamping parts should have lower requirements for standard precision level and surface roughness level as much as possible when they can be used normally, which is conducive to product exchange, reducing waste, and ensuring stable product quality. The planned stamping parts should be conducive to processing them using existing equipment, process equipment, and process flow as much as possible, and to extending the service life of the stamping die. The stamping parts for car wiper housings and car wiper housings should be stamped by professionals in the car industry. Mainly focused on deep drawing. In our country, this part is concentrated in large factories such as car manufacturers, tractor manufacturers, and aircraft manufacturers, and large-scale stamping and deep drawing factories are not yet common. Stamping of professional parts such as cars. It is formed by punching and cutting.

Many of these enterprises are classified as standard parts factories, as well as some stamping factories. Nowadays, there are many small factories in the vicinity of some car or tractor factories. Electrical equipment stamping factory. This type of factory is a new industry that is expanding along with the development of electrical appliances, and these factories are concentrated in the south. Daily necessities stamping factory. Make some handicrafts, tableware, etc. These factories have also made significant progress in recent years.

A good cross-section of metal stamping parts should first control burrs and minimize them, followed by pursuing a bright strip. For many hardware stamping parts that require comparison, customers will specify the proportion of the bright strip in the entire cross-section, which is the scope of stamping.
