Abstract
The utility model discloses a machine body of a hydraulic press, and belongs to the technical field of hydraulic presses. The machine body of the hydraulic press comprises an upper cross beam, a base, a left upright post and a right upright post, wherein both the upper cross beam and the base are arranged between the left upright post and the right upright post; the left and the right lateral faces of the upper cross beam and the left and the right side surfaces of the base are respectively connected with the inner side surface of the left upright post and the inner side surface of the right upright post through a key, a key slot, and a plurality of composite members including bolts and disk springs. The machine body of the hydraulic press is low susceptible to deformation, thereby ensuring that the hydraulic press works stably, and improving the pressing accuracy.
Description
Technical field
The utility model belongs to the hydraulic press technical field, relates in particular to a kind of hydraulic press fuselage.
Background technology
Be used for the frame structure that the fuselage of the hydraulic press of the complex-curved flexible forming of heavy duty metal sheet material is made up of entablature, column, base etc.Described column comprises two left columns and two right columns, and four root posts place between entablature and the base, and every root post is accordingly by interconnecting between a pull bar and entablature and the base.Pull bar runs through entablature, column and base, described pull bar through hydraulic pressure rise draw processing after, connect locking nut respectively at the two ends of pull bar.Said structure is from the transmission angle analysis of power, and the active force that is arranged in the master cylinder of entablature below passes to entablature by cylinder body, and entablature passes to pull bar by the locking nut that is connected the pull bar upper end.Though pull bar has certain pretightning force, hydraulic press is still to have the gap in compacting between entablature and base and the column during workpiece.Because the existence in gap, hydraulic press plays pendulum, and easily causes whole frame deflection, and the compacting precision is lower.
The utility model content
The technical problems to be solved in the utility model provides a kind of not yielding, guarantees the hydraulic press working stability, improves the hydraulic press fuselage of compacting precision.
The utility model comprises entablature, base, left column and right column, and entablature and base place respectively between left column and the right column; The and arranged on left and right sides face of entablature and the and arranged on left and right sides face of base interconnect by key and keyway and a plurality of sub-assembly of being made up of screw and disk spring with the medial surface of the medial surface of left column and right column respectively.
As improvement of the present utility model, above-mentioned left column and right column are respectively overall structures.
As improvement of the present utility model, described keyway is arranged on the left surface of entablature or base or the groove on the right flank, forms with groove combination on the medial surface that is arranged on left column or right column.
Adopt the airframe structure in the utility model, when master cylinder is had an effect, active force passes to entablature by the master cylinder cylinder body, entablature passes to column by key, column then passes to base by key again, because between key and entablature, column, the base is that face cooperates, so hydraulic press is in stable closed state all the time; In addition, the sub-assembly of forming by disk spring and the screw vibration that when bearing serious unbalance loading, causes of absorption liquid press fuselage effectively.Above-mentioned hydraulic press airframe structure is not yielding, has guaranteed the stability when hydraulic press is worked, and has improved the compacting precision of hydraulic press.
Be two single-columns with right column with existing left column be that the structure of two single-columns is compared, integrally-built left column and integrally-built right column have higher strength and stiffness in the utility model, the stability when further having guaranteed hydraulic press work.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the cutaway view along A-A line among Fig. 1.
The specific embodiment
As shown in Figure 1, present embodiment comprises entablature 1, base 2, left column 3 and right column 4, and above-mentioned left column 3 and right column 4 are respectively overall structures.
As shown in Figure 2, interconnect by a plurality of sub-assemblies of forming by screw 6-1 and disk spring 6-2 6 in addition between entablature 1 and the right column 4.Also interconnect by means of a plurality of sub-assemblies 6 respectively between base 2 and the right column 4 in the same manner, between entablature 1 and the left column 3, between base 2 and the left column 3.
Claims (3)
1, a kind of hydraulic press fuselage comprises entablature, base, left column and right column, it is characterized in that: entablature and base place respectively between left column and the right column; The and arranged on left and right sides face of entablature and the and arranged on left and right sides face of base interconnect by key and keyway and a plurality of sub-assembly of being made up of screw and disk spring with the medial surface of the medial surface of left column and right column respectively.
2, a kind of hydraulic press fuselage according to claim 1, it is characterized in that: above-mentioned left column and right column are respectively overall structures.
