The one-material multi-forging die forging method has certain constraints (or unsuitable conditions). As long as one of the following contents is not suitable for one-material multi-forging (especially not suitable for one-die multi-forging, continuous multi-forging, U-turn die forging and Compound die forging and other forming methods): such as heavy forgings, large horizontal projection area of forgings, too complicated forging shapes, too narrow forging temperature range, large forging die bore depth, excessive final forging deformation without blank forming, The number of billet making steps in one-fire forging is ≥3, the number of forging dies needs to be increased, and the number of forging equipment needs to be increased, etc. The one-material multi-forging die forging method is a systematic project. Effectively determining the constraints and suitable conditions is one of the prerequisites for achieving the reliability, effectiveness and timeliness of the one-material multi-forging.

In the forgings used today, poor temperature control or carelessness in the production process will cause a series of defects, which will greatly reduce the quality of the forgings. In order to eliminate this defect in the forgings, the metal must be improved first. In order to avoid the sensitive working pressure of steel parts in the whole forging process, it can increase the relative density of metal materials, not only make it less and less smooth and dense, but also make it a high aluminum alloy. When carburizing in alloy steel , Body shape is broken. Secondly, improve the appearance regulations and specifications of steel castings to make them close to the parts. This not only reduces the cost of metal composite materials, but also shortens the laser cutting time. It can further improve the production efficiency of very forged forged parts and molded parts. This speed far exceeds the speed of drilling production and processing. The forging parts of the forging press have strong adaptability, not only for simple production and processing, but also for producing parts with relatively complex shapes. Therefore, in the entire manufacturing process, no or only a small amount of drilling or solving is required. After the forging processing technology has been moderately improved, the product quality has been greatly improved, and the minimum forging defect rate has been greatly reduced. Therefore, as a variety of industrial equipment, forging parts can play a stronger role. For special tools such as Barr, the surface of the forged material will be affected during the forging process, and an extended heat treatment method is applied to the forged material to eliminate the different time characteristics of the internal and external structural changes of the forging. Forging materials, reduce welding stress and structural ground stress, and ensure more reasonable characteristics and service life of cast steel materials, and have strong adaptability

Forging parts refer to a processing method that deforms metal by impact or pressure between the upper and lower anvils or forging dies. Date: 2017-12-10 Mining equipment forging manufacturers: Forgings refer to the processing method that deforms the metal by impact or pressure between the upper and lower anvils or forging dies. It can be divided into free forging and model forging. If the shape of the workpiece is the only requirement, then forging is only one of the processing techniques. However, in many cases, forging is the only way to obtain the necessary mechanical properties. In order to obtain all the advantages of the forging process, the requirements for its performance must be indicated in the forging process specification. The process specification should include requirements for material standards and any additional requirements, as well as possible exceptions. In addition, the minimum tensile performance required and the maximum and minimum hardness at a specific position of the part should also be indicated. During free forging, the metal to be processed is compressed between the upper and lower anvils to produce deformation, and the metal can flow freely in all directions on the horizontal plane, so it is called free forging. The equipment and tools used in free forging are more versatile, and the quality of forging parts varies. However, the shape and size of free forging parts are mainly guaranteed by the forger's operating technology, which requires high technical level, high labor intensity, low productivity, low precision of forgings, large machining allowance, and can not obtain more complex. shape. Therefore, it is mainly used for single-piece, small batch production and repair work. For large forgings, free forging is the only production method.

Professional manufacturer of forged passenger car wheels-Zhejiang Huaguang Precision Manufacturing Co., Ltd. Zhejiang Huaguang, a professional manufacturer of forgings, Zhejiang Huaguang Precision Manufacturing Co., Ltd., Zhejiang Huaguang`s main products include construction machinery forgings, locomotive forgings, auto parts forgings, flange forgings, and excavators. Let us first understand what is a forging? Forging refers to a workpiece or blank obtained by forging and deforming a metal blank. By applying pressure on the metal blank, it produces plastic deformation, which can change its mechanical properties. According to the temperature of the blank during processing, forgings can be divided into cold forging, warm forging and hot forging. Cold forging is generally processed at room temperature, and hot forging is processed at a temperature higher than the recrystallization temperature of the metal blank Forging products supplied by Zhejiang Huaguang Precision Manufacturing Co., Ltd. " Product name: Forged passenger car wheels Forging equipment: hydraulic press Processing properties: hot forging Processing materials: according to customer requirements Processing basis: Wheel forgings are designed and processed according to customer drawings, samples or functional requirements Scope of application: cranes, transportation, nuclear power, marine, industry, bridges, aerospace, etc. Welcome to inquire about forging products of Zhejiang Huaguang Precision Manufacturing Co., Ltd.

How to face the status of the casting and forging market In recent years, Zhejiang Huaguang Precision Manufacturing Co., Ltd. has made great progress in forging products. From a macro point of view, it has also adapted to the overall development level of my country. However, we have also seen our own shortcomings. The consumption of large castings and forgings in my country Both the volume and output are developing at an average annual growth rate of about 20%, but the average annual growth rate of large-scale castings and forgings imports exceeds 25%, which exceeds the growth rate of consumption and domestic production in the large-scale castings and forgings market. In particular, the forging industry as a whole has a large gap with foreign countries, with a self-sufficiency rate of less than 60%, and there is still a lot of room for development. At present, although my country's large-scale casting and forging manufacturing industry appears to have strong production capacity, its ability to provide products to the market is still insufficient. Some high value-added products with high technical quality, good economic benefits and excellent quality are still not produced or rarely produced by Chinese enterprises, and a large number of markets are squeezed by foreign manufacturers. Zhejiang Huaguang Precision Manufacturing Co., Ltd. has been continuously investing scientific research funds in this regard, increasing the upgrading of forging equipment, and continuously improving the quality and added value of forging products. The next 10 to 15 years will still be a critical period for advancing my country's industrialization process. The metallurgy, electric power, petrochemical, shipbuilding and other industries will continue to develop, and the demand for large castings and forgings will increase accordingly. Although my country has built three large-scale casting and forging production bases, their equipment an
