Open Die Forgings The principle of rough selection
      Open Die Forgings is the first step in Open Die Forgings. The quality of the Open Die Forgings will have an important impact on the quality, performance, longevity and economic benefits of the Open Die Forgings. Open Die Forgings Blank processing technology, equipment accuracy and performance determines the quality of the blank. Open Die Forgings rough directly affects the accuracy of turning, and turning the quality of the grinding and grinding accuracy and efficiency. So the choice of Open Die Forgings rough works in the Open Die Forgings processing plays a very important role, Open Die Forgings rough selection principle, should meet the requirements of the use of the premise, as much as possible to reduce production costs, so that products in the market Competitive. Next is the Open Die Forgings rough selection principle, the following:
      1. Principle of process:
      Open Die Forgings use requirements determine the shape of the blank shape, a variety of requirements and shape the use of the characteristics of the formation of the corresponding blank forming process requirements. The use requirements of Open Die Forgings are embodied in the external quality requirements such as their shape, size, machining accuracy, surface roughness, and internal quality requirements such as chemical composition, metal structure, mechanical properties, physical properties and chemical properties. For different Open Die Forgings requirements, you must consider the process characteristics of the Open Die Forgings material (eg forging performance, weldability, etc.) to determine what blank forming method is used. Select the blank forming method at the same time, but also take into account the follow-up machining processability. Some of the complex, difficult to use a single forming method of forming the rough, it is necessary to consider the possibility of combining a variety of forming programs, but also need to consider whether these combinations will affect the machinability of machinability.
       2. Principles of Adaptation:
       In the choice of rough forming options, but also consider the principle of adaptability. Based on the structural shape, dimensions and working conditions of the Open Die Forgings, choose the blank scheme. For example, for the ladder shaft parts, when the step diameter difference is not large, the bar can be used; if the difference is large, it is appropriate to use forging rough. Open Die Forgings working conditions are different, the choice of rough type is also different.
       3. Production conditions to take into account the principle:
       Open Die Forgings blank forming program according to the site production conditions to choose. On-site production conditions include the actual level of workmanship, the status of the equipment and the possibility and economy of the outreach, but at the same time consider the use of more advanced blank manufacturing methods due to production development. To this end, the blank selection, the company should analyze the existing production conditions, such as equipment capacity and staff technical level, as far as possible the use of existing production conditions to complete the rough manufacturing tasks. If the existing production conditions are difficult to meet the requirements, you should consider changing the Open Die Forgings materials and / or blank forming methods, but also through outsourcing or outsourcing solution.
       4. Economic principles:
       The principle of economy is to make Open Die Forgings the lowest cost of manufacturing materials, energy, and cost. In the choice of Open Die Forgings blank type and the specific manufacturing methods, should meet the requirements of the use of parts under the premise of a number of preselections for economic comparison, from which the overall cost of production options. In general, the choice of blank types and manufacturing methods, should be rough size, shape and finished parts as close as possible, thereby reducing the processing margin, improve the utilization of materials and reduce the workload of machining. But the more accurate the rough, the more difficult to manufacture, the higher the cost. Therefore, the production program should be used when the high precision, high productivity of the rough manufacturing method, then although a large investment, but the increase in rough manufacturing costs can be reduced by the consumption of materials and mechanical processing costs are compensated. The general rule is that a single piece of small batch production, can be used for free forging, manual arc welding, sheet metal fitter and other forming methods, in the mass production can be used machine modeling, forging, submerged arc welding or other.
