鍛造鍛件時模鍛變形工藝
一、制坯工步或制坯模膛
1. Blank manufacture step or blank mold chamber

鐓粗:鐓粗坯料,使坯料的高度減小,直徑增大。用于餅類鍛件的制坯。使坯料直徑與鍛件相接近,有利于鍛件的成形,減少終鍛錘擊次數,提高模膛壽命,并能除去坯料側表面上的氧化皮。
Upsetting: upsetting billet reduces the height of the billet and increases the diameter. The billet used for the forgings of the cake. The diameter of the blank is close to the forging, which is beneficial to the forming of the forgings, reducing the number of hammer strikes, improving the life of the die, and removing the oxide skin on the surface of the blank.

壓扁:壓扁坯料,使坯料變扁增寬,壓扁后坯料的長度幾乎不變。多用于外形扁寬的鍛件制坯。
Flattening: flattening the blank so that the blank becomes flat and widened, and the length of the billet is almost unchanged after flattening. Most of the forgings are made of flat and wide shape.
滾擠:使坯料局部橫截面增大,相鄰部分減小,稍許增加坯料的長度。經過滾壓后,坯料沿軸線準確分配體積,使表面光滑圓渾。操作時坯料繞軸線作90°翻轉,不作進給。
Roll extrusion: the local cross section of the billet is enlarged, the adjacent part is reduced, and the length of the billet is slightly increased. After rolling, the volume of the billet is accurately distributed along the axis, making the surface smooth and round. During operation, the billet is turned 90 degrees around the axis without feeding.

拔長:減小坯料局部橫截面面積,使坯料長度增加,從而使坯料的體積沿軸線重新分配。操作時坯料繞毛坯軸線作90°翻轉并沿軸線向模膛進給。
Pull out: reduce the local cross sectional area of billet, increase the length of billet, so that the volume of the billet is redistributed along the axis. During operation, the billet is turned 90 degrees around the blank axis and fed along the axis to the mold cavity.

壓肩:使坯料的局部截面略有增加,壓下部分展寬。操作時坯料一般不翻轉。
Press shoulder: make the local section of the billet slightly increase, and the part of the press is widened. In general, the blank is not turned over.

彎曲:使坯料軸線彎曲,獲得與鍛件水平投影圖形相近的形狀,以適應軸線彎曲的鍛件終鍛成形要求。
Bending: bending the blank axis and obtaining a shape similar to that of the horizontal projection of the forging to meet the final forging requirement for the forging of the axis.

二、模鍛工步或模鍛模膛
Two. Die forging or die forging die

預鍛:通過預鍛獲得與終鍛接近的形狀,以利鍛件在終鍛時的最終成形,能改善金屬流動條件,有利終鍛的充滿,避免終鍛產生折疊并提高終鍛模膛壽命。
Pre forging: the shape close to the final forging is obtained by pre forging, so that the final forming of the forgings in the final forging can improve the metal flow conditions, benefit the filling of final forging, avoid the final forging and increase the life of the die die.

終鍛:通過終鍛獲得最終的鍛件形狀,所有的鍛件都必須經過終鍛。終鍛模膛周圍有飛邊槽,用以容納多余的金屬。
Final forging: the final forging shape is obtained through final forging, and all forgings must undergo final forging. There are flash grooves around the final forging chamber to accommodate excess metal.
