Forging a common process for forging

In order to improve the efficiency of forging, we query the original data that is forging assembly drawing, part drawing; Quality standard for forgings acceptance; The production conditions of the forging factory, including the specifications, performance and existing state of the machine tools and forging process equipment, the technical level of the workers, the ability of the factory to make self-made process equipment, and the ability of the factory to supply power and gas, etc. Design manuals and relevant standards required for the design of production process procedures and process equipment design; Domestic and foreign advanced manufacturing technology data, etc. Forging products

To find out the design principle, the forging design process should be able to achieve the quality of the machine, to meet the technical requirements specified on the drawings provided by customers; Should make the process have higher productivity, so that the product delivery as soon as possible; Try to reduce this; Pay attention to reduce the labor intensity of workers, production.

Determine the step content, analyze and study the forging assembly drawing; Determine the blank; Develop the forging production process route, select the positioning base surface; Determine the equipment used in each process; Determine the tools, fixtures, measuring tools and auxiliary tools used in each process; Determine the technical requirements and inspection methods of each main process; Determine the allowance of each procedure, calculate the procedure size and tolerance; Determine cutting parameters; Determine the quota of working hours.

The forge will use different methods depending on the shape needed to produce the forgings. Other forgings are done in a variety of ways. Although the principles of these methods are different but still have a lot in common, the difference is different form of cutting movement forgings, but because of all kinds of machine tools and tools used are different, so they have their own process characteristics and application range.

Turning is a cutting method in which the forging rotates as the main movement and the turning tool acts as the feed movement. The main movement of forging turning is forgings rotating, especially suitable for rotary surface forgings, shaft forgings, etc., is the straight-line movement of cutting tools for feed movement.

Grinding is a method by which the grinding tool rotates at a high linear speed and the forging factory works on the surface of the forgings. The use of abrasive tools is usually called a grinder. In the process of grinding, the self-sharpening effect of the grinding wheel is the cutting edge of the general cutting tool which is not found in other cutting tools.

Boring is the main movement of the boring tool rotation, is the cutting method of forging or boring tool feed movement. Boring is mainly carried out on the milling and boring machine. Boring is a further forgings drilling, boring can expand the aperture, lift, reduce the surface roughness, but also can better correct the original hole axis deviation. Boring can be divided into rough boring, half fine boring and fine boring.

Planing is a cutting method in which the planer and forgings reciprocate in a horizontal direction relative to a straight line. Planing is one of the main methods of planing, which is commonly used in the small batch production of forgings. Common planer machine tools are shaver, planer and planer.

Milling is a cutting method in which the milling cutter rotates as the main movement and the forging and milling cutter act as the feed movement. Milling is one of the main plane methods, milling, forging with the table milling cutter rotation is the main movement.

Broaching is the use of broach under the action of tension for axial movement, forgings, the surface of the method. The use of multi-tooth broach, one by one from the workpiece to cut a very thin metal layer, so that the surface to achieve higher precision, can be forged to obtain a smaller roughness value.

Drilling is a method of drilling tool and forging relative movement and axial feed movement, forging on the forging hole. Drilling is the basic hole method in forgings.
