Description
Technical field
The present invention relates to hydraulic press technical field, in particular to a kind of improved cylinder girder construction for hydraulic press,
The manufacture method of hydraulic press and cylinder girder construction with the cylinder girder construction.
Background technology
Hydraulic press is a kind of general machinery, for automobile, aircraft, ceramics, plastics every profession and trade material forming technique.Weight
Type hydraulic machine is the indispensable jumbo in the fields such as national defence, military project, space flight, nuclear power, shipbuilding, is the mark for signifying national strength
Will is equipped.Cylinder and beam are the basic components of hydraulic press, and the hydraulic medium acted in cylinder produces huge pressure by cylinder
Load, pressure loading is delivered on upper and lower beam, and the balanced system of force of closing is formed through column.How pressure loading is delivered to beam
On, i.e., load transmission chain is influence press intensity, the key issue of rigidity Design.Cylinder-load beam transmission refers to that a kind of load is passed
Pass chain relation.
Fig. 1 shows the cylinder load beam transmission schematic diagram of existing hydraulic press.Oil pressure pi is acted on cylinder bottom 1 ', produce to
On thrust P, and act also on simultaneously on piston, produce equivalent downward thrust (P), under its effect, move beam 2 ' downwards
Motion, suppresses forging 3 '.It can be seen from balanced system of force power transfer chain principle, the upward power of cylinder bottom 1 ' is acted on, through cylinder mouthful flange
Contact surface (A faces), is transferred on the bottom surface of upper beam 4 ', its value is also P.Above-mentioned cylinder-load beam transmission chain relation is built upon
On load transmission relation on cylinder mouthful flange and soffit between respective carrier face, i.e. A faces, this is also referred to as " cylinder oral instructions power
Type " load transmission chain.
Fig. 2 shows the structural representation of existing another hydraulic press, and which show the cylinder beam knot of cylinder bottom power transmission type
Structure.As shown in Figure 2, shown is wire wrapped frame, and steel wire floor is by upper and lower beam 1 ", 2 " (being half circular beam) and column 3 "
Winding pretension turns into a framework for support, and this is the load transmission relation of one " cylinder bottom power transmission type ".Cylinder bottom 4 " is oil pressure pi's
Under effect, pressure P is directly delivered on the bottom surface of upper beam 1 ", without passing through cylinder flange.Using " cylinder oral instructions power type " and " cylinder
All very extensively, they respectively have advantage and disadvantage for application in the press of two kinds of load transmission chains of bottom power transmission type ", engineering.It will be made below
Summary.
For cylinder oral instructions power type load transmission chain, make to be used as maximal bending moment M as shown in fig. 1, on beam central cross section, such as
Shown in Fig. 3, exactly cylinder passes the position of beam herein, there is very big hole, and it weakens the intensity of such as upper beam.The deformation in hole
The change of hole radius of curvature can also be caused, it makes the tangential stress on hole side further increase, and sees Fig. 3.This is to cause beam strength
The maximum hidden danger of problem, has to increase the thickness of all structures in hole to improve intensity.
As shown in fig. 1, in cylinder oral instructions power type load transmission chain, beam, the load transmission of cylinder are logical contact surface A therebetween
And carry out, but contact situation can deteriorate with the increase for adding/unloading cycle-index, contact it is uneven contact stress is increased severely,
Influence the intensity of beam.For example, 8000 tons of cylinder oral instructions power type single cylinder press of factory of China, fresh processed beam, cylinder, due to matching relationship
Good, contact is good, and the working life of cylinder is up to 700,000 times；And after long-term work, because contact condition deteriorates, a new cylinder is old
Beam coordinates, and the life-span of cylinder is then down to 250,000 times, it is seen that coordinate A faces the good and bad relation of contact it is great.
Cylinder bottom active force P is balanced by the bearing reaction Q on flange, thus bears huge tension Qz on cylinder barrel wall,
As shown in Figure 4, which show the structural representation of the cylinder bottom 5 ' of the hydraulic cylinder in the hydraulic press in Fig. 1, and two are formed
Area of stress concentration：Cylinder bottom (is generally group with casing wall transition region I (radius is R, as shown in Figure 4) and flange stress concentration zones II
Mould assembly line).The cylinder body of the overwhelming majority is destroyed all in the two areas.
In order to improve the intensity in I areas, then the thickness of cylinder bottom is increased, 1.5-2.5 times of casing wall thickness is, thick cylinder bottom is curved
Song deformation is small, so as to reduce the bending stress in the area；The stress concentration degree in I areas can be obviously reduced in R increases.Obviously arrange for this two
Apply the weight for all considerably increasing cylinder.R increase, also add the length of cylinder, but not increase the effective travel of cylinder, because smart
Leakproof fit piston can not possibly run to R fillet areas.
In addition, the machining accuracy and surface smoothness that improve I, II area are to increase the important measure of cylinder fatigue life, but together
When add processing cost and the cycle of cylinder.Alternatively it is also possible to carry out roller process to II areas, the residual pressure on increase top layer should
Power, so that the fatigue resistance in II areas is greatly improved, while also increasing the processing cost of cylinder.
For cylinder bottom power transmission type load transmission as shown in Figure 2, due to cylinder bottom support, therefore cancel cylinder mouthful flange, because
And the II areas of stress concentration disappear, as shown in Figure 2, a series of disadvantages associateds disappear therewith.In addition, can be by cylinder bottom and cylinder point
From, assembling cylinder bottom formula cylinder structure is formed, thus area of stress concentration I areas also disappear, a series of disadvantages associateds also disappear therewith.
Further, combination cylinder bottom is without knuckle R, thus improves cylinder inner chamber operation mileage rate (piston can be moved
Dynamic longer distance).
The cylinder girder system system of " cylinder bottom power transmission type " load transmission chain, its shortcoming is also clearly.Due to cylinder bottom top surface with it is upper
Soffit is contacted, and cylinder bottom is covered by soffit completely, thus loses the installing space of cylinder bottom top surface, it is impossible on cylinder bottom top surface
The parts such as replenishing valve, safety valve, valve block are installed；Also external booster can not be to be mounted directly to cylinder bottom top surface.Hydraulic cylinder is placed in
Below soffit rather than in beam, the height of frame is considerably increased, this is a significant drawback.
In current engineering, more than oil cylinder more than thousands of tons of, avoid " cylinder oral instructions power type "；And use " cylinder bottom power transmission
Type ".But it is completely covered by soffit thus extremely serious at the top of cylinder to have impact in " cylinder bottom power transmission type " cylinder beam relation
Its use scope.
