Abstract
The utility model relates to a pressing machine capable of adjusting the pressure centre of a die, which comprises the pressing machine and is characterized that four nitrogen springs are further included, wherein the four nitrogen springs are respectively arranged on the four corners of the pressing machine and are symmetrical to the die center; and each nitrogen spring weights 3 to 5 tons. The power of the nitrogen springs is great and steady, so that the pressure centre of the die can be closer to the geometric centre of the die, instead of being far away from the geometric centre of the die caused by irregularly-shaped stamped parts. Therefore, the utility model can remarkably reduce the deviation value of the pressure centre of a stamping die from the geometric centre of the die, i.e. the center of the pressing machine.
Description
Technical field
The utility model relates to the forcing press of a kind of adjustable mould preparation tool Center of Pressure.
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.
The utility model content
In order to address the above problem, the utility model discloses the forcing press of a kind of adjustable mould preparation tool Center of Pressure.It is characterized in that, also comprise four nitrogen springs, four nitrogen springs be separately positioned on four angles of forcing press and with the position of mold center's symmetry.Wherein, nitrogen spring is 3～5 tons a nitrogen spring.
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 Center of Pressure and the mould geometric center that adopt the utility model can obviously dwindle diel are the deviation value at forcing press center.
Description of drawings
Fig. 1 is the utility model embodiment schematic diagram.
Among the figure, 1 is nitrogen spring, and 2 is forcing press, and A is assumed to and adjusts the front mold Center of Pressure, and B is for utilizing Mould's Pressure Center after the nitrogen spring adjustment, and C is mould geometric center, lathe Center of Pressure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model 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 utility model then can reduce the deviation value at Mould's Pressure Center and forcing press center.
Consult Fig. 1, on four angles of forcing press 2 and with the position of mold center symmetry, arrange a same nitrogen spring 1 respectively.During punching press, the pressure-bearing table top of nitrogen spring 1 working end and patrix design contacts simultaneously, then the fitting like a glove with mold center and forcing press 2 centers 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, behind employing the utility model, Mould's Pressure Center is made a concerted effort obviously approaching with the lathe Center of Pressure.
Therefore, the utility model 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.
