Description
Technical field
The invention belongs to the fields of forging, and in particular to a kind of mold and its user with horizontal forging calibration function
Method.
Background technique
The forging production technique of forging is general are as follows: heating-base-blocking-finish-forging-trimming-correction.Forging products
During trimming, the more complicated position of some shapes can be deformed, such as: the bar portion I-shaped structure of connecting rod is in trimming
Lower die will appear the case where H font section horizontal opening becomes larger afterwards, form " eight " font；And some complex-shaped forging, it is such as bent
Axis trimming process can generate horizontal distortion, these horizontal distortions can not be corrected by normal correction mould, generally take at end
Deformation meets forging drawing requirement after the design of compensating property reaches trimming when design of forging die, but this design is not only complicated, needs
Test is repeated and adjusts determining offset, and feelings are deformed due to the variation of temperature and mold state in process of production
Condition is unstable, and final forging's block dimension quality stability is poor.
Summary of the invention
The present invention provides a kind of mold and its application method with horizontal forging calibration function, and structure is simple, and operation is just
Victory can complete the correction for the horizontal distortion that forging generates during die forging and trimming, expeditiously to meet die-forging forming
Requirement.
Technical scheme is as follows:
Under a kind of mold with horizontal forging calibration function, including correction upper mold, horizontal compression skewback, bolt A, correction
Mould moves horizontally insert die, spring and bolt B, and correction upper mold and correction lower die are equipped with the type chamber for placing forging, two horizontal pressures
Tight skewback is symmetrically mounted on the two sides of correction upper mold using bolt A；The type chamber two sides of correction lower die are symmetrically arranged with sliding slot, two water
Dynamic insert die is translated to be individually positioned in two sliding slots；Correction lower die two sides are symmetrically arranged with circular hole, and the circular hole bottom is set
There is screw thread, the spring is placed in the circular hole, and bolt B, which sequentially passes through, moves horizontally insert die and the spring is mounted on school
In positive lower die；It is corresponding with insert die position is moved horizontally that level compresses skewback.
The mold that there is horizontal forging calibration function, wherein level compresses the inclined-plane of skewback and moves horizontally insert
Inclined-plane gradient having the same on the outside of mould, works in coordination.
The mold that there is horizontal forging calibration function, wherein the type chamber and two water of correction upper mold and correction lower die
The working face for translating dynamic insert die collectively constitutes correction chamber.
The mold for having horizontal forging calibration function, preferred embodiment is the working face for moving horizontally insert die
It is equipped with printing mark.
A kind of application method of the above-mentioned mold with horizontal forging calibration function, includes the following steps:
1) correction upper mold is fixed on press ram, correction lower die is fixed on press bench, makes to correct
Upper mold is located at press machine upper dead center position, and forging is put into correction lower die；
2) move downward correction upper mold, when the horizontal inclined-plane for compressing skewback connects with the inclined-plane moved horizontally on the outside of insert die
When touching, level compress the slope driving of skewback move horizontally insert die and generate horizontal movement, spring starts to be compressed；
3) when correction upper mold, which moves to working surface, to be bonded completely with correction lower die working surface, level compresses skewback
Insert die will be moved horizontally and be depressed into horizontal terminal, the type chamber of correction upper mold and correction lower die and two move horizontally the work of insert die
Correction chamber is collectively constituted as face, completes the correction to the horizontal distortion of forging；
4) so that correction upper mold is carried out backhaul movement upwards, during level compresses skewback and gradually moves up, move horizontally edge
The block mould side that moves outward under the action of the spring is mobile；
5) when level, which compresses skewback, and moves horizontally insert die is detached from, it is extensive under the action of the spring to move horizontally insert die
Initial position is arrived again；
6) when correction upper mold returns to press machine upper dead center position, forging is taken out from correction lower die, completes the school of forging
Just.
The invention has the benefit that the present invention be can carry out simultaneously vertically and horizontally both direction to forging shape and
The corrected mold of change in size realizes the control to the position of forging horizontal distortion, guarantees forging's block dimension qualification and quality
Stability.For the forging that forging side has printing to identify, printing mark can be set on moving horizontally insert die, realized
The mark of the horizontal position of forging prints, and forging side is required can to move horizontally insert for the forging faced directly
The working face of mould is designed to the forming faced directly Shi Xians to forging side.The configuration of the present invention is simple operates convenient, high production efficiency.
