在锻压生产中采用小损耗模锻是进一步提高金属材料利用率的有效途径之一。据前时所述原理,环类锻件小损耗模锻的模具结构见图1。模具由上模座1和下模座7组成。在下模座中放上垫板8、下模5、顶杆9、顶出杆10、润滑模膛的管子6(箭头示出喷涂润滑剂的方向)。在上模座里装上凸模3、顶杆12、项出杆11、管子6。嵌套4由拉紧螺钉2固定,以保证嵌套开闭。在模具零件接近预镦粗毛坯变形开始时,嵌套4封闭凹模5。仅靠嵌套自重保证接触平面紧贴。在过程的第一阶段,金属向
The use of small loss forging in forging production is an effective way to further improve the utilization of metal materials. According to the principle of the previous period, ring forgings small loss forging die structure shown in Figure 1. Mold by the mold base 1 and the mold base 7 components. Place the pad 8, the lower mold 5, the ram 9, the ejector pin 10, and the tube 6 that lubricate the mold cavity (the arrow shows the direction in which the lubricant is sprayed). In the punch holder installed punch 3, the mandrel 12, the item 11, the tube 6. Nested 4 by the tightening screws 2 fixed to ensure nesting. At the beginning of the deformation of the die part near the pre-upset blank, the die 4 is closed 4 to close the die 5. Only rely on nested self-respect to ensure contact with the plane. In the first phase of the process, the metal to
