Abstract
The invention relates to a method for adjusting the pressure center of a mould by using nitrogen cylinders, which is characterized in that four nitrogen gas springs with the same specification are arranged at four symmetrical corners of the mould, thus ensuring that the pressure centers of the four nitrogen cylinders and the geometric center of the mould are in coincidence. The pressure enters of the nitrogen cylinders are used for adjusting the pressure center of the mould so as to lead the pressure center of the mould to be much closer to the geometric center of the mould. The invention can obviously improve the condition that the pressure center of the mould is deviated from the center of a pressure machine which is also named the geometric center of the mould so as to better protect the pressure machine and the mould.
Description
Technical field
The present invention relates to a kind of method of utilizing nitrogen spring to adjust Mould's Pressure Center.
Background technology
The Center of Pressure of diel when mould uses preferably near in addition overlap with the forcing press center.If there are bigger off-centre in Mould's Pressure Center and forcing press center, will aggravate the wearing and tearing of guide rail of press machine and cause the unbalance loading of mould to use serious even damage that cause lathe, mould.
At present, in design, be easy to guarantee that the geometric center of mould overlaps with the center of forcing press.But because technological means and working condition restriction are difficult to guarantee that Mould's Pressure Center overlaps with the forcing press center in concrete die design process.For example: automobile die work profile all is the three dimensions solid surface, often a mold is concentrated compound punching press contents such as moulding, deburring, punching, flange, lateral punching, can not accurately calculate the Center of Pressure of mould and the position relation of mould geometric center with present technological means at all, cause the skew of Mould's Pressure Center and location, forcing press center like this.During punching press, mould and forcing press all exist than large eccentricity load, reduce die life, the degree of wear of aggravating guide rail of press machine simultaneously.
Summary of the invention
In order to address the above problem the present invention
OpenA kind of method of utilizing nitrogen spring to adjust Mould's Pressure Center.It is characterized in that, at first arrange four nitrogen springs of pressure greatly on four of the mould symmetry angles, thereby guarantee that the Center of Pressure of 4 nitrogen springs overlaps with the mould geometric center, utilize the Center of Pressure of nitrogen spring to adjust Mould's Pressure Center, thereby make the more close mould geometric center of Mould's Pressure Center.
Because the strength of nitrogen spring is big, and strength is steady, therefore can makes the more close mould geometric center of Mould's Pressure Center, and can not make Mould's Pressure Center away from the mould geometric center because of the punching parts out-of-shape.So, the invention has the beneficial effects as follows that Center of Pressure and the mould geometric center that can obviously dwindle diel are the deviation value at forcing press center.
Description of drawings
Fig. 1 is an embodiment of the invention schematic diagram.
Among the figure, 1 is nitrogen spring, and A is assumed to and adjusts the front mold Center of Pressure, and B is for utilizing Mould's Pressure Center after the adjustment of nitrogen cylinder, and C is mould geometric center, lathe Center of Pressure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done more detailed explanation.
It is the basic demand of mould design that Mould's Pressure Center overlaps as far as possible with the forcing press center, if there are bigger off-centre in Mould's Pressure Center and forcing press center, will aggravate the wearing and tearing of guide rail of press machine and cause the unbalance loading of mould to use serious even damage that cause lathe, mould.Automobile die work profile is mainly the 3 D stereo curved surface at present, and the direction of power is difficult to determine with the center of making a concerted effort during punching press; And stamping procedure tends to concentrate compound punching press contents such as moulding, deburring, punching, flange, lateral punching, and present technological means can't be determined Mould's Pressure Center at all.Adopt the present invention then can reduce the deviation value at Mould's Pressure Center and forcing press center.
Consult Fig. 1, on four angles of mould symmetry, arrange four same nitrogen springs 1.During punching press, the pressure-bearing table top of nitrogen spring 1 working end and patrix design contacts simultaneously, the fitting like a glove with mold center and forcing press center with joint efforts of nitrogen spring 1.Wherein, the mould geometric center of determining when the C point designs for the engineering staff also is the geometric center of lathe simultaneously.Suppose that the A point is for increasing the Center of Pressure of nitrogen spring front mold punching press product.Draw the B point for increasing making a concerted effort of Center of Pressure behind the nitrogen spring according to the Center of Pressure solving method.As can be seen from the figure, after employing this method, Mould's Pressure Center is made a concerted effort obviously approaching with the lathe Center of Pressure.
Therefore, the present invention can obviously reduce the deviant at Mould's Pressure Center and forcing press center, and the eccentric load of having born when having reduced mould and forcing press punching press makes mould and lathe work more steady, has improved the punching press condition.Thereby the assurance die life reduces the machine tool guideway degree of wear.
Claims (2)
1. method of utilizing nitrogen spring to adjust Mould's Pressure Center, it is characterized in that, this method is at first arranged the nitrogen spring of four same model specifications on four angles of mould symmetry, thereby guarantee that the Center of Pressure of four nitrogen springs overlaps with the mould geometric center, utilize the Center of Pressure of nitrogen spring to adjust Mould's Pressure Center again, allow the more close mould geometric center of Mould's Pressure Center.
