Abstract
The invention relates to a forging and pressing method for a long-shaft forged piece. According to the method, a hoisting traveling crane is adopted for assistance and a tripper is hung, then the other end of the long-shaft forged piece is hitched through the tripper, and as one end of the long-shaft forged piece is clamped by a claw beam of a forging and pressing operation machine, when the long-shaft forged piece is forged by a hydraulic press, the stress of the long-shaft forged piece is more uniform, which solves the problem that the long-shaft forged piece is bent due to larger length during the forging and pressing processes, and also avoids the problem that in the prior art, the diameter allowance of the forged piece is increased to overcome deformation, so that the increase of the diameter allowance exceeds the working range of the operation machine.
Description
Technical field
The present invention relates to the axle class and make the field, relate in particular to a kind of forging method for long-axis forging.
Background technology
In the prior art, the forging mode of long-axis forging is to utilize the jaw of forging and pressing operating machine to vise an end of long-axis forging, then forge by hydraulic press, but utilize this kind forging method stressed buckling phenomenon that occurs of long-axis forging meeting after forging and pressing, in order to reduce the appearance of buckling phenomenon, usually adopt the diameter surplus (namely diameter of forgings being carried out overstriking) that increases long-axis forging, make its least possible bending in the forging and pressing process, but the diameter surplus that increases long-axis forging has following shortcoming:
(1) diameter of increase long-axis forging also just increases raw material, has greatly improved production cost.
(2) because the diameter surplus of long-axis forging increases, cause the weight of this long-axis forging also to increase, even can exceed the manipulator working range and the situation that causes to produce.
Summary of the invention
The applicant is studied improvement for the problems referred to above, and the another kind of forging method that is used for long-axis forging is provided, and it does not need to increase diameter of forgings, and economical with materials reduces production costs.
The technical solution adopted in the present invention is as follows:
A kind of forging method for long-axis forging is characterized in that may further comprise the steps:
The first step: forging and pressing operating machine comes an end of clamping forge piece;
Second step: rane trolley is hung servo-actuated upender, and the chain end of servo-actuated upender is socketed the other end of described forging.
The 3rd step: forging and pressing operating machine work, rane trolley are moved and are realized the movement of forging on lower anvil, by anvil on the hydraulic press and lower anvil described forging are forged.
Beneficial effect of the present invention is as follows:
The inventive method is by the rane trolley power-assisted and hangs upender, then entangle by the other end of upender with long-axis forging, because an end of long-axis forging has passed through the claw beam clamping of forging and pressing operating machine, thereby when hydraulic press is forged, long-axis forging stressed more even, overcome long-axis forging in the forging and pressing process owing to the long buckling problem that causes of length, also avoided increasing in order to overcome distortion the diameter of forgings surplus in the past, cause exceeding the problem of the working range of manipulator, utilize the method not need to increase diameter of forgings, effectively saved material and production cost.
Description of drawings
Fig. 1 is the forging schematic diagram of the inventive method.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Method of the present invention may further comprise the steps:
The first step: as shown in Figure 1, come an end of clamping forge piece 2 by the claw beam 1 of forging and pressing operating machine;
Second step: the suspension hook 401 by rane trolley 4 is hung servo-actuated upender 5, and the other end of the chain end socket forging 2 of servo-actuated upender 5 is finished installation.
The 3rd step: forging and pressing operating machine work, rane trolley 4 are moved and are realized the movement of forging on lower anvil, by anvil on the hydraulic press and lower anvil described forging are forged.
Utilize the specific implementation process of the inventive method as follows:
In the forging and pressing process, the claw beam revolution of forging and pressing operating machine, because the other end of forging is enclosed within the chain end of servo-actuated upender, forging is rotated, the simultaneously movement of forging on lower anvil is to finish by the movement of the rane trolley of hanging upender, at last by anvil realization on the hydraulic press to the forging and pressing work of forging.
The structure of above-mentioned hydraulic press, servo-actuated upender, forging and pressing operating machine and operation principle all belong to existing known technology.
Above description is explanation of the invention, is not that limited range of the present invention is referring to claim, in the situation that without prejudice to basic structure of the present invention, the present invention can do any type of modification to the restriction of invention.
