Abstract

The utility model relates to a pressure machine frame, which is composed of a base, a cross beam, two upright posts tightly fixed by a positioning pin and a bolt. The upper part and the lower part of the inside of the pressure machine frame are respectively provided with a half dovetailing shape boss with inclined surface. The half dovetailing shape boss is respectively matched and attached to the half dovetailing shape groove at the outside of the cross beam and the base. The inclined surface combining structure has the self-locking function and the structure can improve the stress condition of each component. Compared with the same product, the utility model has small size and light weight, which can make the material saved by 20%-28%. The assembling, transportation, and processing cost are reduced by 5%-10% and the total cost is reduced by 25%-35%. The utility model can be used in various mechanical presses and screw presses.

Description

Press frame

The utility model relates to metal forming machinery, more clearly says so to be used for the hydropress frame of big machinery forcing press and various fly press (as friction screw press, high power screw press, electric screw press, hydraulic screw press, swing fly press etc.).

In various forcing presses, frame is a key components and parts, and it is related to the precision and the service life of whole forcing press.The hydropress frame in past mostly adopts the combined frame structure with the four-pull-rod tension.It is by base, crossbeam, constitute between two columns between the two, four pull bars, eight retainer rings, eight big nuts.The pull bar two ends are threaded, and base, crossbeam and column are tightened together at the pull bar two ends with big nut.Therefore, in fact four pull bars, eight retainer rings and eight big nuts are exactly the securing member that base, crossbeam and column are fixed together.The hydropress frame volume of this structure is big, weight is big.The machining difficulty will be processed with heavy duty machine tools.Assembly difficulty is big, be through overbaking dress or cold drawn assemblying.Lifting, transportation inconvenience will be used large lifting equipment, and transportation time space utilization rate is low.Therefore, its manufacturing, cost of transportation are all very high.

The purpose of this utility model is to overcome above-mentioned shortcoming and defect, provide a kind of simple in structure, volume is little, in light weight, easy to manufacture, processing is simple, can assemble in applying unit, dismounting, transportation, lifting are convenient, the hydropress frame that cost is low.

In order to achieve the above object, the utility model by base, be installed on the base about two columns, be installed in about two above the column crossbeam and the securing member that above-mentioned parts are fixed together formed.About the inside upper part and the bottom of two columns respectively have one and half swallow-tail form inclined-plane boss, two outsides respectively have half a swallow-tail form inclined plane groove that matches with two column bottoms and top respectively about base and crossbeam.About two columns be installed in the left and right sides of base and crossbeam respectively, half swallow-tail form inclined-plane boss and half swallow-tail form inclined plane groove coincide.Securing member is bolt and the alignment pin that column and base, crossbeam are fixed together.About two columns by the plate combination, fixedly constitute.

Since about the half swallow-tail form inclined-plane integrated structure that adopts of two columns and base, crossbeam, all the technology power thus faying face bear.Crossbeam when stressed, about two columns and base be in the self-locking process always, the precision that has remained whole frame is constant.About two columns not only born the effect of four pull bars in the hydropress frame in the past, and born torque resistant effect and counter-bending metamorphosis.Simultaneously, the stressed centre of form is changed, reduced the stressed span of crossbeam and base greatly.Compare with the like product in past, span can reduce 15%.The reducing of span reduces crossbeam and the actual moment of bearing of base, and then reduced the flexural deformation amount of deflection of crossbeam and base, improved its stress condition greatly.In other words, the intensity of crossbeam and base is corresponding improves greatly.The existence of above-mentioned advantage makes with the part geometry size of tonnage forcing press to be dwindled, and material has been saved in weight saving, has reduced cost.

Task of the present utility model comes to this and finishes.

The utility model is simple in structure, volume is little, in light weight, stress condition good.Machining, assembling, convenient transportation can be decomposed into parts with integral body earlier during transportation in applying unit (user) assembling, thereby have saved transport space and lifting cost usefulness greatly.The utility model alleviates 20～28% weight than the past like product, thereby has saved 20～28% material.Processing, assembling, packing, freight have saved 5～10%.Therefore, totle drilling cost of the present utility model has reduced by 25～38% more in the past.It can be widely used in the metal forming machinerys such as punching machine, fly press.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further explanation.

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the structural representation of hydropress frame in the past.

Among Fig. 1, the utility model embodiment by base 3, about two columns 2, crossbeam 1 and securing member form.Securing member is by column 2 and base 3, column 2 are constituted with bolt 5 and the alignment pin 4 that crossbeam 1 is fixed together.The inside upper part of column 2 and bottom respectively have one and half swallow-tail form inclined-plane boss 6, and half swallow-tail form inclined plane groove 7 with the crossbeam 1 and base 2 outsides coincide proper respectively.

As can be seen, two columns 2 are by plate combination, fixed forming about present embodiment among Fig. 2.

Shown in Figure 3, the hydropress frame in past by four screw rods (four pull bars) 5 and nut thereof with base 3, about two columns 2, crossbeams 1 tighten together.Each parts stressing conditions is abominable, and volume is big, and weight is big, fee of material, cost height, processed complex, transportation inconvenience.

Present embodiment is in light weight, volume is little, material is economized, convenient transportation.Its totle drilling cost like product has in the past reduced by 30%, and it can be widely used in various big machinery forcing presses, in the fly press.
