1 引言 高强度模锻外链片如图1所示。该零件形状复杂,成形难度较大。某厂采用自由锻锤制坯,摩擦压力机终锻成形,从制坯、成形工艺、模具结构型槽设计和设备使用技术等方面采取了有力措施,消除了锻件折叠等缺陷,保证了锻件的质量,并且适合于高效率的大批量生产。2 成形工艺的制定及防止折叠的措施 外链片沿轴线长度方向各断面基本是工字形断面,模锻时易产生折叠。在制定模锻
1 Introduction High strength forging outside the chain piece shown in Figure 1. The shape of the complex parts, forming more difficult. A factory using free forging hammer blank, friction press final forging, from the blank, forming process, mold structure groove design and equipment technology and other aspects of the adoption of effective measures to eliminate the forging defects such as folding to ensure that the forging Quality, and suitable for high-efficiency mass production. Form forming process and prevent the folding measures External chain along the axial length of the cross-section of the basic section is I-shaped, easy to produce when die forging fold. In the development of forging
