The main processes of stamping parts processing in stamping factories are punching, bending and stretching. These three processes have different requirements for stamping materials. Dongguan Fortuna has been committed to precision metal stamping for more than 10 years, and has accumulated rich experience in blanking, bending and stretching. Next, the editor of Dongguan Fortuna will analyze the influence of different materials and these three stamping processes. 1. PunchingPunching stipulates that the raw material should have sufficient plasticity to ensure that the material does not crack during punching. After punching the soft material, a punched part with a smooth cross section and a small slope can be obtained. After punching, the hard metal stamping material has a large cross section. And the thick material is a ductile material, which is very easy to cause tearing after punching;2. BendingBending and forming materials need to have sufficient plasticity and low strength limit; high plasticity plates are not easy to crack during bending; materials with low strength limit and low elastic mold, the rebound deformation after bending is small, very It is easy to obtain bending parts with accurate dimensions; the metal stamping parts with great ductility must have a large relative bending half warp when bending, otherwise the material is very easy to crack during the whole bending process;3. StretchingThe drawing process of the material not only stipulates that the deep depth of the drawing is as small as possible, the appearance is as simple and round as possible, but also that the material has good plasticity. Cracking of tensile parts, etc.;
Metal stamping parts are widely used in all aspects of our lives, and their requirements are getting higher and higher. It is necessary to have some inspection standards for metal stamping parts to ensure the quality and stability of stamping parts. Next, Xiaobian Yiwei will introduce the inspection standards of metal stamping parts to you.1. Parts Inspection Guidance (Standard) BookSimple metal stamping parts can be inspected by comparing the various sizes marked in the drawings, followed by the use of various measuring instruments, such as tape measures, calipers, pass and stop gauges, etc. In addition, pay attention to some important tolerances marked on the drawings, and whether the tolerance range is consistent with the drawings. For some high-precision products, the tolerance requirements are strict. 2. Samples of metal stamping partsFor some parts without inspection tools but with complex shapes that cannot be expressed in 2D drawings. A quadratic circle test can be used. The sign board is a very intuitive reference. It can be seen whether the structure is qualified, the surface treatment, and the cutting edge.3. Excellent quality of metal stamping partsThe adaptability of the metal stamping material to the stamping forming process becomes the stamping forming performance of the sheet metal, which includes: crack resistance, mold fit and shapeability. 1) Crack resistance refers to the ability of stamping materials to resist cracking, which is generally measured by parameters such as forming limit; 2) Mold fit refers to the ability of the sheet to achieve consistency with the shape of the mold during stamping; 3) Formability refers to the ability of a part to maintain its shape in the mold after demolding. It is obvious that the higher the forming limit, the better the mold fit and settability, the better the stamping formability of the material. 4. Special inspection tool for metal stamping partsThe special inspection tool for metal stamping parts should be based on the actual situation of the parts, and it needs to be used skillfully.The above are the inspection standards for metal stamping parts. For products with extremely high requirements, Dongguan Fortuna has specially developed automatic visual inspection equipment for quality inspection. Automated visual inspection equipment can detect 100% of the product, and the internal high-resolution dedicated camera can detect the product from all dimensions to determine whether the product meets the standard. This can achieve the goal of maximum inspection efficiency while ensuring 100% reliable component quality.
In order to ensure the accuracy of mold processing, Dongguan Fortuna uses Mitsubish low-speed wire cutting machines to process mold parts.Low speed wire cutting is a kind of EDM wire cutting. It uses continuous moving thin metal wire as electrodes to perform pulse spark discharge on the workpiece to remove metal and cut into shape. It is mainly used for processing various high-precision parts. Let me introduce to you the advantages of slow-moving wire cutting. 1. Perfect qualityThe quality of the machined surface is improving day by day(1) Nanosecond high peak current pulse power supply technology(2) Anti-electrolysis (BS) pulse power supply2.

Efficiency improvementSignificantly improved processing efficiency(1) High processing efficiency(2) Processing efficiency of larger thickness workpieces(3) Processing efficiency of workpieces with varying thickness
1. The dimensional accuracy does not meet the requirements, and there are many reasons for this situation: wrong drawing, improper use of the dial, no need for trial cutting, inaccurate measurement, thermal effect of cutting, etc. After the above problems occur, the solutions are as follows: clearly check the size requirements of the part drawings, use the turntable correctly, perform trial cutting, check and adjust the zero position, and measure correctly, do not measure when the workpiece temperature is high, please use cutting fluid Reduce the temperature.2. The reason for the taper: the turning tool is gradually worn in the middle; when clamping, the workpiece overhangs for a long time, and the cutting force moves the front end during machining of the CNC lathe shaft. When using the chuck to clamp the longitudinal feed in rotation, the rails of the lathe are not parallel to the axis of the lathe. After the above problems occur, the solutions are as follows: select the appropriate cutting tool material or reduce the cutting speed; reduce the extension length of the workpiece as much as possible, or use the rear center support at the other end to increase the clamping rigidity; adjust the lathe spindle and the lathe guide rail. parallelism.3. Reasons for unqualified roundness: The clearance of the main shaft of the lathe is too large; the blank allowance is uneven, and the flank feed is too large during the cutting process. After the above problems occur, the solutions are as follows: Check the spindle clearance and adjust it properly before turning. If the spindle bearings are severely worn, replace the bearings. Finish turning after semi-finishing.This article focuses on the knowledge point of CNC lathe shaft machining, through this article, you can see that CNC lathes are also often used as an auxiliary process to add or improve features on parts manufactured using different processes. Because CNC lathes can provide high tolerances and surface finishes, they are ideal for adding precision rotational features to parts that already have a basic shape.
