Embodiment 1

[0031] A method for forming a tire die forging billet for a long thin plate complex die forging, the specific operation steps are as follows:

[0032] (1) Prepare the tire mold required for forging forming ( figure 2 ), block ( image 3 ), platen ( Figure 4 ) and tools such as pliers;

[0033] (2) Preheat the tire mold and tools to 200 ° C ~ 300 ° C, and heat the heated bar ( Figure 5 ) is placed on the flat anvil surface, and the processes of flattening, elongating and shaping are carried out along the radial direction of the bar to ensure Image 6 Medium and long square size requirements;

[0034] (3) Carry out size clamping along the length direction of the block, partially elongate the tail end, and use a semicircular pressing plate to make a dimple on the end face of the tail to ensure Figure 7 Shape and size requirements;

[0035] (4) Clamp the tire mold with the manipulator ( figure 2 ) is placed on the flat anvil of the forging hammer, and the Figure 7 Th...

Abstract

The invention provides a loose tooling forging blank forming method of a long-sheet complicated die forge piece and belongs to the field of aviation product plastic forming. According to the loose tooling forging blank forming method of the long-sheet complicated die forge piece, an original free forging blank method is changed, free forging loose tooling forming is applied to die forging blank forming, a simple tooling is designed, materials are accurately calculated, steps of square forging, bar pulling, indenting, heading, necking, clamp pressing, final forming and the like are utilized, the shape of a blank is similar to that of the forge piece, final forming of the die forge piece is facilitated, the whole streamline of the die forge piece is reasonable, the problems that the shape is not regular, the size is slightly large, die forging forming size mismatching exists and the like due to the original free forging blank method can be avoided, and the loose tooling forging blank forming method of the long-sheet complicated die forge piece has the advantages that the die manufacturing is simple, costs are low, the period is short, forging heating number is small, the material utilization ratio is high, and the like.

Description

technical field [0001] The invention belongs to the field of plastic forming of aviation products, and in particular relates to a method for forming a tire die forging blank of a complex die forging such as a long thin plate. Background technique [0002] The complex structure of long and thin plates is a typical structure of aviation product parts, such as figure 1 As shown, the internal structure of the part is complex, the size of each section varies greatly, the overall thickness is thin, and the outer dimension is large and irregular. The blank is usually formed by casting, but for some parts with high stress conditions, the design requires die forging. take shape. Die forgings of this type of structure are difficult to form, especially for the shape and quality of the preformed billet. Many times, need large equipment tonnage and other disadvantages. Contents of the invention [0003] The present invention changes the original free forging billet forming method, a...
