When forging and processing a forging, the first thing we need to do is to determine the forging process of the forging first, and know what process method to use to forge the forging in the next step. The forging process plays a very important role in the whole forging process, and it is also the premise to initially determine whether the forging can guarantee the quality. As long as the head is opened, the whole process can be better ensured, therefore, how important the scheme of the forging process is, let's first look at how the scheme of the forging process is determined.

The purpose of economic analysis of forging processing is to explore technical solutions and pursue greater economic effects. Any production process should not only formulate the process, determine the process parameters and process equipment, but also discuss the economic effect.

The principle of determining the forging process is to create more material wealth with less labor consumption. The optimization of process is to find the minimum value in the total consumption of materials, equipment, energy and labor under the premise of ensuring the quality and quantity of products. For the forging process, it can be specifically: high dimensional accuracy of forgings, organization and performance to meet the requirements, low raw material consumption, small equipment investment, simple tools, low energy consumption, low labor intensity, and no pollution to the environment.

The effect of technical economy is carried out by comparative method. When comparing process options, there may be more than two options, and in order to make the conclusions of the analysis correct and reliable, an exhaustive list of possible or alternative options is used. To this end, to carry out forging process analysis, to explore a variety of processes, programs, for technical and economic analysis and selection of ****** process program preparation conditions. The task of general process analysis can be summed up as follows: according to the functional characteristics, material, shape, dimensional accuracy, quality requirements and production batch of forgings, under the conditions of existing or available equipment, devices, tools, energy, inspection means, management level and personnel quality, various process schemes can be put forward for use.

During process analysis, the following questions must be considered and answered:(1) whether the function of forgings can be met;(2) whether the technical conditions and quality standards of drawings can be met;(3) Whether the structure of forgings is reasonable and whether there is any excess dressing;(4) Whether the machining allowance can be reduced;(5) Whether the deformation force or deformation work can be reduced;(6) Whether the metal flow line meets the requirements;(7) Whether there is any omission in the process to ensure the quality; (8) Whether the working procedures and steps have been reduced;(9) Whether the material is fully utilized and whether it is possible to forge together with other parts, with multiple pieces in one die or multiple pieces in one blank;(10) Have you considered advanced technologies such as cold forging, precision forging, rolling, local die forging, segmented die forging, combined die forging, forging welding, etc. The steps of process analysis, process analysis to specific forgings as the object, the comprehensive use of metal pressure processing principles, forging technology, metal science and heat treatment, forging equipment and automation and other disciplines of knowledge and factory production practice. Starting from the analysis of the function and technical requirements of the parts, explore various possible deformation methods, design a reasonable forging structure, determine the appropriate machining allowance, tolerance and process dressing, and draw the forging diagram. According to the shape and size of forgings and deformation mode, the force required for deformation is calculated, and the main forging equipment is selected. Determine the heating temperature according to the forging material and deformation mode, and select the heating mode and heating equipment. According to the type of forging equipment, deformation mode and blank size, the blanking equipment is selected. Determine the process route according to the quality requirements of forgings, and select the equipment such as trimming, correction, fine pressing, heat treatment, cleaning, inspection and flaw detection. Determine the production beat and productivity according to the production batch, and then calculate the number of equipment. According to the equipment performance characteristics and productivity, calculate various consumption data, such as material, power, material, auxiliary materials and mold consumption. According to the selected process, taking into account the production organization, equipment characteristics, determine the production of the required plant area and the number of production workers, auxiliary workers, technical and management personnel, and then analyze the advantages and disadvantages of the various processes, such as: labor conditions, environmental protection and its technical and labor skills needs.

It should be noted that technically unreliable processes need to be screened and eliminated before alternative process options can be derived. The so-called unreliable process includes the following aspects: unable to complete the forming of forgings; Dimensional accuracy does not meet the requirements of drawings; Metal flow line is unreasonable or cannot meet the requirements of parts for metal flow line; Can not meet the performance requirements of part strength, rigidity and hardness; Can not meet the requirements of quality tolerance and dimensional tolerance for the use of parts or subsequent processing; Can not obtain the required equipment or mold, the supply of necessary power, fuel, raw materials and auxiliary materials cannot be obtained; serious public hazards or damage to the health of operators cannot be prevented or proper preventive measures cannot be obtained.

Process analysis is a systems engineering problem. Although it is still an analogy and inference based on experience, it is a method characterized by the personal mental work of the craftsman, so the person engaged in this work is required to be familiar with the existing production methods and master the characteristics, scope of application and restrictions of various process schemes. Can correctly calculate the technical parameters, understand the current situation, trend and development trend of forging production at home and abroad, and can infer and predict according to the actual conditions.

After the above analysis and comparison process, the processing method of specific forgings has been understood. If the analysis is based on existing knowledge and experience, the proposed number of process options will be limited to the existing mode of production, on the basis of further thinking, put forward new ideas. In view of the inherent shortcomings of the existing various programs, in the deformation mode, reduce the process, save energy, save materials may be the case, improve or change the forging, the idea of a new process program. The new concept has to go through the above procedures to calculate various technical data to form a complete process plan.
