Embodiment 1

[0039] Such as figure 1-2 shows a specific implementation of the forging edge trimming correction system involved in the present invention. The forging edge trimming correction system includes: a worktable 9, a lower backing plate 8, an edge trimming correction assembly 5, a first drive assembly, a second drive assembly, at least one set of hydraulic devices, a guide assembly, a mounting assembly, and a temperature sensor.

[0040] In this embodiment, the lower backing plate 8 is disposed on the workbench 9 .

[0041] In this embodiment, the edge trimming correction assembly 5 is used for trimming the forging and performing correction while trimming, such as figure 1 As shown, the trimming correction assembly 5 includes a first trimming correction assembly at the top and a second trimming correction assembly at the bottom, and the first trimming correction assembly can be positioned relative to the second trimming correction assembly Move up and down in the vertical directio...

Embodiment 2

[0052] Different from Example 1, as image 3 As shown, the hydraulic device is arranged in two groups, and the hydraulic cushion plunger cylinder in each group of the hydraulic device is connected to an accumulator, and the back pressure provided by the hydraulic device of the two groups is different, so different groups of The hydraulic cushion plunger cylinder can have different pressures, so that the back pressure exerted on different parts of the forging with complex shapes is also different, realizing a more flexible trimming correction function.

Abstract

The invention relates to the technical field to forging, in particular to a forged piece edge-cutting and correcting system. The forged piece edge-cutting and correcting system comprises an edge-cutting and correcting assembly, a first driving assembly and one or more sets of hydraulic devices, wherein the edge-cutting and correcting assembly is used for conducting edge cutting on a forged piece and correcting the forged piece while conducting edge cutting on the forged piece; the first driving assembly is connected with the edge-cutting and correcting assembly, the edge-cutting and correctingassembly applies force to the forged piece under the action of the first driving assembly; and each hydraulic device comprises a plurality of first hydraulic cylinders, the acting ends of the multiple first hydraulic cylinders act on the edge-cutting and correcting assembly under driving of second driving assemblies to provide back pressure for the edge-cutting and correcting assembly, and the connecting number of the second driving assemblies and the first hydraulic cylinders is adjustable. The forged piece edge-cutting and correcting system can adjust the back pressure according to different products and is flexible and high in applicability.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a trimming correction system for forgings. Background technique [0002] The typical forging process of forgings is usually: blanking-flattening (bending)-pre-forging-finishing-trimming-correction. The traditional process is prone to straightness deformation caused by bending moment during the forging and trimming process. Subsequent needs to pass The hydraulic press is used for point pressure alignment, but there will be many problems in the alignment process: (1) residual stress will be generated, which will affect the product accuracy; (2) the thermal alignment process usually requires separate finishing equipment and alignment molds, which not only increases the investment , and increase the process and production cycle; (3) For forgings that have been deformed, thermal correction can only play a certain role, and cannot completely eliminate deformation. [0003] Therefore, ...
