(1) Molding die forging head Molding refers to the use of blanks for two forgings, after heating and forging into the first forging, 180. Turning the head, using the pliers to clamp the first forging and then forging another forging. The weight of the forged head is between 6 and 7 kg, and the length of the ingredients is not more than 300 mm.
(2) A fire, multiple pieces, and multiple pieces of fire are continuously forged several forgings with a heated bar. Each forging of a forging piece, the forging piece is separated from the rod by a cutter. Used in small forgings with a single weight below 0.5g. The number of forgings for continuous forging is generally 4 to 6 pieces.
(3) One or more pieces of one or more pieces are forged two or more forgings on the same module at a time. It is used for small forgings with a weight below 0.5kg and a length not exceeding 00mm. Forgings with a drop can be offset by the misalignment that can occur when swaging a single forging. The advantages of a multi-piece are obvious, but when the mold is manufactured, it is necessary to pay close attention to strictly control the positional accuracy between several final forging dies.
(4) Use of the skin and jaws For the gears with larger internal holes (such as the rear axle gears of the car), the thickness of the skin can be appropriately designed. The splicing of the skin can meet the requirements of forging another smaller cake. For shaft parts with clamp jaws, the use of clamp heads should be considered, especially for large forgings such as crankshafts. One of the methods is to properly change the length of the jaws so that the cut jaws can be used to forge another smaller forging.
(5) Forgings of forgings can forge two kinds of forgings at a time, so that the varieties of forgings and molds are reduced and easy to manage. There are also advantages in that the metal is evenly distributed and more easily formed. When determining the step and method of the die forging, the possibility of forging is considered.
