Abstract
The utility model relates to the field of forging equipment and discloses a forging press with a pre-stressed frame structure, comprising a power device, a forging tool and the pre-stressed frame structure, wherein the pre-stressed frame structure comprises four pull rods each sleeved by a column sleeve; the pull rods pass through an upper beam and a lower beam; the two ends of each pull rod are provided with threads and are screwed with nuts to apply pre-tightening force to the upper and lower beams; and the column sleeves are clamped between the upper and lower beams to keep the distance between the upper and lower beams. The forging press with the pre-stressed frame structure reduces the amplitude of the stress applied to the frame structure during working, improves the anti-fatigue capacity of the pre-stressed frame structure and prolongs the service life of the forging press.
Description
Technical field
The utility model relates to the forging equipment field, specifically is a kind of forging press that possesses the prestressed frame structure.
Background technology
Forging and pressing are by the thickness of the relative motion change workpiece of instrument or the machining process of cross sectional shape.Forging press is the fabrication tool of forging and pressing.The stress amplitude that the frame structure of the part of forging press, especially forging press is born is very big, reaches several ton forces even tens of ton force.And the anti-fatigue ability of the frame structure of prior art forging press is lower.
Therefore, cases such as column fracture, base fracture took place in actual applications.
The utility model content
The purpose of this utility model is to provide a kind of frame structure anti-fatigue ability strong forging press.
For realizing above goal of the invention, the utility model forging press comprises power set, forging tools and prestressed frame structure; The prestressed frame structure comprises four pull bars, column sleeve of every rod outer sleeve; Pull bar passes entablature and sill, and the pull bar two ends are provided with screw thread, and the cover top nut applies pretightning force for entablature and sill; Column sleeve is clipped between entablature and the sill, keeps the distance between entablature and the sill, and column sleeve can be the common metal workpiece, also can be the metal processing piece that the part transformation by waste and old equipment forms.
Pull bar adopts the high strength alloy steel manufacturing to form, and the screw thread at two ends adopts German SOLT standard, is provided with dual weakening groove, makes screw thread evenly stressed.Power set are drive units of forging press, for the work of forging press provides power; Power set can be pump control oil hydraulic systems, also can be valve control oil hydraulic system or hydraulic pressure system.
A kind of forging press that possesses the prestressed frame structure of the utility model, the suffered stress amplitude of frame structure has improved the anti-fatigue ability of prestressed draw-bar when having reduced work, has prolonged the service life of prestressed draw-bar.
As Fig. 2 is the stressed schematic diagram of prestressed frame.The entablature of forging press is stressed to be nominal pressure F
1, the pulling force that pull bar is subjected to is F
2, the deflection of pull bar
The pressure that column sleeve is subjected to is F
3, the deflection of column sleeve
Suppose that prestressing force is F
4Work as F
1When being directed downwards,
Work as F
1When direction makes progress,
If d＜D, side F
2＜F
4, the suffered tension F of frame structure
5=0; Frame structure institute compression chord
Therefore, the suffered stress amplitude of frame structure
Fig. 3 is nominal pressure F
1" power-distortion (P-Δ l) " figure of the utility model forging press of=70MN, the suffered stress amplitude of frame structure is Δ F=8.238MN as shown in FIG., only is 11.7% of nominal pressure.As seen, the technique effect that technical solutions of the utility model are brought is significantly, has improved the anti-fatigue ability of frame structure greatly, has improved the stability of forging press.
