High speed Gong processing requirements

The surface quality standard of high speed computer gong parts

1、 The purpose and action of high speed Gong processing temperature control on formability. The appearance of products, physical properties of materials and forming cycle are significantly affected by die core temperature. In general, it is ideal to keep the core temperature low to increase the injection times. However, the forming cycle related to the shape of the product (core structure) and the type of finished material also depends on the need to increase the core filling temperature.

2、 In order to prevent the temperature control of stress, this is the problem of forming material, the only requirement is cooling rate. The cooling time is short. Even if some parts are hardened and some parts are soft, the stress caused by uneven shrinkage can be avoided. That is to say, proper temperature control can improve the properties of cooling stress.

3、 Temperature control of crystallizing degree adjustment of forming material. High molding temperature is usually required to adjust the degree of crystallization and improve the mechanical properties of crystalline materials such as polyamide, polyacetate and polypropylene.

  1. Computer gong processing fastening parts, check whether the fastening parts loose, damage phenomenon, the way is to find the same specification of metal stamping parts for replacement.
  2. The edge of metal stamping must be ground after a long time of use. After grinding, the edge surface must be demagnetized without magnetism, otherwise the metal stamping is prone to material blocking.
  3. The punch is easy to break, bend and gnaw in the process of metal mold processing. The punch sleeve is generally gnawed. The damage of the punch and the punch sleeve of metal stamping is generally replaced with parts of the same specification. The punch parameters mainly include the size of the working part, the size of the installation part and the length size.
  4. High speed Gong processing hardware stamping parts, such as pressure plate, uniglue, etc., discharge parts, such as stripper, pneumatic top material, etc., during maintenance, check the parts of the relationship and whether there is damage, repair the damaged parts, pneumatic top material check whether there is air leakage, and take measures for the specific situation, such as the replacement of air pipe damage.

Basic program of large computer gong processing

  1. Large scale computer gong processing accuracy requirements, a mold is generally composed of female mold, male mold and mold base, some may also be multi-component module. Therefore, the combination of upper and lower die, the combination of insert and cavity, and the combination between modules all require high machining accuracy. The dimensional accuracy of precision die for machining mechanical parts is often up to μ m level.
  2. The shape and surface of some products, such as automobile panels, aircraft parts, toys and household appliances, are complex. The surface of the shape is composed of a variety of curved surfaces. Therefore, the cavity surface of the mold is very complex. Some surfaces must be treated mathematically.
  3. The production of small batch mold is not mass production, in many cases, only one batch is produced.
  4. There are many working procedures for large-scale computer gong, and many working procedures such as milling, boring, drilling, reaming and tapping are always used in mold processing.
  5. The service life of repetitive production mould is long. When the service life of a pair of molds exceeds its service life, it is necessary to replace the new molds, so the production of molds is often repetitive.
  6. In the mold production of copying process, sometimes there is neither drawing nor data, and the copying process should be carried out according to the real object. This requires high imitation accuracy and no deformation.
  7. Large computer gong processing mold material is excellent, high hardness, the main material of the mold is made of high-quality alloy steel, especially high life mold steel. This kind of steel has strict requirements from blank forging, processing to heat treatment. Therefore, the establishment of processing technology can not be ignored, and heat treatment deformation is also a serious problem in processing. The basic operation of high-speed Gong machining requires that the working performance of high-speed Gong machining center is an important prerequisite for mold manufacturing industry to process mold efficiently and accurately. Driven by drive technology, many different types of high-speed machining centers with innovative structure and excellent performance have emerged. Do not place obstacles around the high-speed machining center to ensure that the working space is large enough; do not splash water or oil on the ground to ensure that the working ground is clean and dry; do not move or damage the warning signs installed on the machine tool to ensure that the safety warning signs are bright and eye-catching. Don’t touch the switch with wet hands, otherwise it will cause electric shock; before pressing the switch, make sure it is correct, so as to avoid danger caused by wrong connection; be familiar with the position of the emergency stop button, and make sure that you can press it when you need to use it.
