What Factors Affect The Galvanizing Of Metal Stamping Parts
In order to make metal stamping parts beautiful and prevent corrosion, stamping parts manufacturers usually choose to galvanize the surface of the product. The application fields of electro-galvanization are very wide, including machinery manufacturing, 3C electronics, precision instruments, chemical industry, medical industry, aerospace and so on. In the actual production process of the stamping plant, what factors will affect the quality of electrogalvanized?1. The surface of metal stamping parts is not thoroughly cleaned, and a curing film is formed on the surface of the stamping parts, which affects the normal deposition of electro-galvanized parts;2. The carbon content of stamping parts is high. High-carbon steel and cast iron parts will reduce the hydrogen precipitation potential, accelerate the hydrogen precipitation on the surface of the workpiece, and reduce the efficiency of electroplating;3. The stamping parts are bound too tightly, and part of the surface is not electroplated in place during the galvanizing process4. The content of additives in the zinc plating solution is low. If the additive content is low, it will affect the zinc dispersibility, and the coating will appear too thin in some parts;5. Surface corrosion will also reduce the hydrogen precipitation potential, accelerate the hydrogen precipitation on the surface of the stamping parts, reduce the current efficiency, and affect the deposition rate of zinc;6. Low sodium hydroxide content. If the content of sodium hydroxide is low, the current density will decrease and anodic passivation will occur;7. Anode passivation will reduce the effective area, thereby affecting the normal distribution of current

How To Detect The Hardness Of Metal Stamping Parts
With the development of society, stamping products have been applied to various fields. Because the materials used in metal stamping parts are also divided into many types, when producing metal stamping parts in a stamping processing plant, we need to understand the characteristics of the product and the performance of the material. Among them, material hardness is a very important point. Different materials have different testing methods for material hardness.1. Hot rolled steel sheets are usually thick. It is generally stipulated that the Brinell hardness tester is used to test the hardness, and the Rockwell hardness tester can also be used to test the hot-rolled steel plate. When using a portable Rockwell hardness tester to test hot-rolled steel plates, the hrb scale can be used. The test can be carried out without sampling and the operation is very simple;2. The cold-rolled steel plate used for processing metal stamping parts mainly uses Rockwell hardness tester to test the hardness, usually using the hrb scale, and the harder one using the hrc scale;3. The material of the sheet material can use the Webster hardness tester, or the surface Rockwell hardness tester hrn or hrt scale;4. The hardness of the brass plate used for processing metal stamping parts can be tested with the hrb scale of the Rockwell hardness tester; the hrf scale of the softer brass plate and the red copper plate;5. A Webster hardness tester can be used to test aluminum alloy plates used to process metal stampings. When the material thickness is 13mm, a Barcol hardness tester can be used. Busbar hardness tester should be used for pure aluminum plate or low-hardness aluminum alloy plate.

Processing Steps Of Circular Stamping Parts
Stamping factories can produce different kinds of metal stamping parts, and round stamping parts are also one of them. So, when producing circular stamping parts, what processing steps should we take and what should we pay attention to?1. Strip-shaped materials that need to be formed into circular stamping parts;2. Put the main body of the circular stamping strip material used for forming into a two-cavity blanking die for stamping processing. In the stamping process, first locate the bar on the two inclined edges of the parallelogram length, and then position the bar through the hole edge of the circular stamping part after the blanking;3. In order to improve the processing efficiency, two rows of circular stamping parts can be set in the material belt, and the two rows of circular stamping parts can be staggered; when the stamping parts are processed, the positioning of the material belt is located on the four sides of the rectangular material belt Although this method improves the processing efficiency, the utilization rate of stamping materials is not high, and the processing cost is relatively increased.4. The horizontal cross section of the formed circular punch is a parallelogram, and both sides of the parallelogram are inclined in the length direction. The circular stamping parts made from the strip can improve the material utilization rate and reduce the processing cost. Simultaneous stamping. During the processing, the material belt needs to be positioned once during each stamping process, so that the quality of the round stamping parts produced will be better.

How To Design Stamping Parts
Metal stamping parts are a kind of metal products that are widely used, especially punched parts and stretched parts. Generally speaking, the structural design and precision of stamping parts are very important, and a small error will cause huge hidden dangers in use. Stamping parts processing manufacturers must comprehensively consider stamping equipment, mold accuracy, and production costs when designing.1. When we design stamping parts, the shape must be simple and not complicated. If the shape of the stamping part is very complicated, we can split it into several small parts for separate processing, which can greatly reduce Difficulty of production2. The structural design of stamping parts is very important. We design products through molds. The structure of the mold determines the structure of the stamping parts. Therefore, we must ensure the rationality of the structure and reduce the occurrence of waste.3. In order to ensure production efficiency, in the process of producing stamping parts, we should minimize the processing steps and try to simplify the production process, so as to ensure good production efficiency.

Introduction To The Characteristics Of Stamping Parts
Metal stamping parts are a kind of metal processing parts, which can be processed by stamping, bending, stretching and other methods. Stamping is a widely used metal processing technology with high efficiency and large-scale mass production. According to different application fields, stamping parts can be divided into automobile stamping parts, electronic stamping parts, medical stamping parts, etc. Generally speaking, the basic equipment of a stamping factory includes various auxiliary equipment such as shearing machine, CNC punch/laser, plasma, water jet cutting machine, bending machine and uncoiler, leveling machine, deburring machine, spot welding machine, etc. . Generally, the three very important steps in a stamping die factory are cutting, stamping and folding.Stamping parts are sometimes referred to as sheet metal. Usually, the metal sheet is press-molded by hand or with a mold to plastically deform the metal sheet to form a desired shape and size, and it can be further welded or processed with a small amount of machining. More complex parts (such as chimneys, tin stoves and commonly used car shells) are sheet metal parts.Stamping parts processing is called sheet metal processing. For example, use plates to make chimneys, iron barrels, oil cans and pans, vent pipes, etc. The main processes are shearing, punching and bending, bending, welding, riveting, etc., which require certain geometric knowledge. Modern sheet metal technology includes: laser cutting, metal bonding, metal wire drawing, plasma cutting, rolling, metal sheet bending, die forging, water jet cutting, precision welding, etc.

What Needs To Be Paid Attention To in The Production Process Of Precision Stamping Parts
With the improvement of the level of science and technology, people have higher and higher requirements for the precision of products. The stamping industry is no exception. While customer demand for precision stamping parts is increasing, the precision requirements for products are also increasing. In the production process, the production of precision stamping parts must not only consider the shape and size of the product, but also the impact of stamping dies, punches and other matters.1. It is necessary to regularly check the performance of the punch press and the parallelism and perpendicularity of the worktable.2. The production of precision stamping dies must be strictly controlled. If the stamping factory does not have the ability to independently develop molds, it needs the support of a more powerful mold supplier. The quality of precision stamping dies determines the quality of precision stamping parts. Therefore, we need to ensure that there are no mistakes in this part of the mold, otherwise the consequences will be disastrous.3. Before installing the mold, be sure to strictly check whether the mold and the press are clean, and check the lubrication of the mold guide post.4. In the production process, the springs should be checked and replaced regularly to avoid spring problems and affect the quality of precision stamping parts.5. Stamping processing plants need to formulate work standards to ensure that stamping workers operate according to the standards when installing stamping dies.6. In the actual production process, if the knife edge of the mold wears out, it needs to be repaired or replaced in time, otherwise the mold will be more damaged.In addition to the same precautions as conventional stamping parts, the main purpose of ensuring the quality of precision stamping parts is to pay attention to the maintenance and maintenance of punches and stamping dies. Stamping factories can only produce qualified precision stamping parts if they ensure the accuracy of the punch and die.

Application Of Hydroforming Technology On Stamping Parts
Hydroforming is a shaping technology that refers to the use of liquids or molds to shape workpieces, also known as hydraulic forming. Hydroforming technology can do many stamping processes, such as punching, bending, stretching, etc. Using hydroforming technology, stamping processing plants can process a variety of complex stamping parts, such as bellows. The stamping products produced by hydroforming have the advantages of good surface quality, simplified process and simplified molds, which greatly simplifies the processing procedures of the stamping processing plant. However, because the liquid directly acts on the stamping parts, it is much more difficult to achieve the sealing requirements, and the operation process is more complicated.Hydroforming has outstanding advantages:1. This technology is isostatic forming, which relies on high-pressure media to change the shape of the sheet. The raw material is compressed in the normal direction and is under stress in three directions, which can better perform partial forming and make it easier to process more complex stamping parts;2. The traditional steel-steel contact forming method is changed, which can effectively reduce the scratches of stamping products and optimize the appearance of the product to a large extent.3. Break through the limitations of traditional stamping in the forming direction of stamping parts.4. Multiple processes can be carried out at once, which is beneficial to reduce the number of processes and molds.
