A mold with horizontal forging correction function and its application method

Abstract

The invention belongs to the field of forging, and particularly relates to a die having a horizontal forging correction function and a using method thereof. The die is characterized by comprising an upper correction die, horizontal compaction inclined blocks, bolts A, a lower correction die, horizontal movement insert block dies, springs and bolts B, wherein mold cavities in which forging pieces are placed are formed in the upper correction die and the lower correction die; the two horizontal compaction inclined blocks are symmetrically mounted on the two sides of the upper correction die by adopting the bolts A; sliding slots are symmetrically formed in the two sides of the mold cavity of the lower correction die; the two horizontal movement insert block dies are separately arranged in the two sliding slots; circular holes are symmetrically formed in the two sides of the lower correction die, threads are arranged at the bottoms of the circular holes, the springs are arranged in the circular holes, and the bolts B sequentially pass through the horizontal movement insert block dies and the springs and are mounted on the lower correction die; and the horizontal compaction inclined blocks correspond to the horizontal movement insert block dies. According to the die having the horizontal forging correction function and the using method thereof disclosed by the invention, a structure of the die is simple, an operation is convenient and quick, and correction of horizontal deformation of the forging pieces produced in die forging and edge cutting processes can be effectively carried out.

Description

technical field [0001] The invention belongs to the field of forging, and in particular relates to a mold with a horizontal forging correction function and a use method thereof. Background technique [0002] The forging production process of forgings is generally: heating - billet making - pre-forging - final forging - trimming - correction. During the trimming process of forging products, some parts with more complex shapes will be deformed. For example, after trimming the I-shaped structure of the rod part of the connecting rod, the horizontal opening of the H-shaped cross-section will become larger in the lower die, forming a " 8" shape; and some forgings with complex shapes, such as crankshaft trimming process, will produce horizontal deformation. Forging drawing requirements, but this design is not only complicated, but also requires repeated tests and adjustments to determine the compensation value, and due to changes in temperature and mold state during the productio...

Problems solved by technology

During the trimming process of forging products, some parts with more complex shapes will be deformed. For example, after trimming the I-shaped structure of the rod part of the connecting rod, the horizontal opening of the H-shaped cross-section will become larger in the lower die, forming a " 8" shape; and some forgings with complex shapes, such as crankshaft trimming process, will produce horizontal deformation. Forging drawing requirements, but this design is not only complicated, it needs to be repeatedly tested and adjusted to determine the compensation value, and the deformation is unstable due to changes in temperature and mold state during the production process, and the final forging has poor dimensional quality stability
