Description

The quick bending press of a kind of thin-walled minor radius steel pipe
Technical field
The utility model belongs to pipe working machinery technical field, is the quick bending press of a kind of thin-walled minor radius steel pipe of design concretely.
Background technology
Its purposes of thin-wall steel tube with setting bending radius is extremely extensive, at present when carrying out bending to thin-wall steel tube, all adopts the operations such as cutting plate, punching press, stretching, welding to complete.Not only prepare many, the complex process of manufacturing procedure, waste time and energy, and the bend pipe shape formed is lack of standardization, precision is low, and the intensity of the bend pipe caused due to welding is difficult to meet the demands.
Utility model content
The purpose of this utility model is just to provide a kind of quick bending press of thin-walled minor radius steel pipe that disposablely can complete setting angle of bend.
For achieving the above object, the technical solution adopted in the utility model is:
The quick bending press of a kind of thin-walled minor radius steel pipe, is characterized in that: be made up of flexible die mechanism and bent into shape mechanism; Wherein, described
The structure of flexible die mechanism comprises, one end be provided with pull-out mechanism flexible link, can be placed on this flexible link has plastoelastic cylindrical mold and die locking mechanism;
The structure of bent into shape mechanism comprises, two of being fixed on bottom frame have setting spacing the lageniform support wheel in Asia and be arranged at described upper rack with the middle ware of described two support wheels apart from corresponding also can the sub-calabash shaped briquetting roller of up-down adjustment.
The additional technical feature forming the quick bending press of above-mentioned thin-walled minor radius steel pipe also comprises:
---in described flexible link, be provided with mould baffle plate;
---described mould baffle plate and be fixed between described pull-out mechanism between shell body to be provided with fixed muffle;
---the round die block that described plastoelastic cylindrical mold is mated by several plastoelastic and described bended pipe internal diameters that can be placed in described flexible link is formed;
---in the centre bore of described module, cover has its thickness to be less than the support set of module thickness;
---described two lageniform support wheels in Asia with setting spacing are in same plane, and the axial plane be situated between is arranged with can the sub-calabash shaped compacted under wheel of up-down adjustment.
The quick bending press of thin-walled minor radius steel pipe provided by the utility model compared with prior art, because this device is made up of flexible die mechanism and bent into shape mechanism, the steel pipe being about to bend is after being inserted in flexible die mechanism, the down-pressing forming wheel bending mechanism it support wheel arranged by bottom and top arranged again, by it press-bending, has the feature of efficiency height and good forming effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the quick bending press of the utility model thin-walled minor radius steel pipe;
Fig. 2 is the structural representation of the flexible die mechanism forming above-mentioned bending press;
Fig. 3 forms the support wheel of bending press and the structural representation of upper and lower briquetting roller.
Detailed description of the invention
Below in conjunction with accompanying drawing, the structure of the quick bending press of the utility model thin-walled minor radius steel pipe and use principle are described in further detail.
As shown in Figure 1, 2, be the structural representation of the quick bending press of the utility model thin-walled minor radius steel pipe.The structure forming this device is made up of flexible die mechanism and bent into shape mechanism two parts; Wherein, the structure of above-mentioned flexible die mechanism comprises the retaining mechanism 5 preventing its lock nut deviating from flexible link to form that one end is provided with the flexible link 2 of pull-out mechanism 1, cylindrical mold that several plastoelastic round die blocks 4 mated with the internal diameter of bended pipe 3 that can be placed in this flexible link are formed and is arranged at top; The structure of bent into shape mechanism comprises two of being fixed on bottom frame 6, and to have according to the periphery of the length setting spacing L of bended pipe 3 be lageniform left and right, the Asia support wheel 7 and 8 of curved surface 9 and what be arranged at upper rack is the sub-calabash shaped briquetting roller 10 of curved surface 9 apart from the corresponding periphery that also can carry out up-down adjustment by hydraulic pressure or other screw mechanisms 17 with the middle ware of two support wheels, and the periphery of this briquetting roller is corresponding with the periphery of two support wheels.
Its operation principle is: first the flexible link forming flexible die mechanism pulled out by drawing mechanism, by several, the plastoelastic round die block mated with the internal diameter of bended pipe 3 is inserted in the cylindrical mold wherein formed again, then by steel pipe socket to be bent in cylindrical mold, lock nut is locked, start drawing mechanism, several elastoplasticity round die blocks are strained and rises steel pipe tensioner the effect of its pulling force is lower outside, this cover is inserted by the flexible link of steel pipe in the circumferential groove of left and right support wheel 7 and 8, sub-calabash shaped briquetting roller is regulated under startup hydraulic pressure or other screw mechanisms, owing to being provided with the spacing of setting between the support wheel of left and right, therefore bending can be formed by steel pipe, on carry briquetting roller reset, lock nut unclamps by reset pull-out mechanism, take out round die block, sweeping thin-walled minor radius steel pipe can be obtained.
In the structure forming the quick bending press of above-mentioned thin-walled minor radius steel pipe,
---rise outside the tension of being inserted in the cylindrical mold wherein formed for the ease of round die block, flexible link is provided with mould baffle plate 13, and be provided with fixed muffle 12 between this mould baffle plate 13 and pull-out mechanism shell body 11, namely this baffle plate can facilitate the tension of elastoplasticity round die block;
---forming above-mentioned cylindrical mold can be that a bodily form elastoplasticity cylinder being provided with the centre bore that flexible link is passed is formed certainly, can reach the purpose of this utility model equally;
---in the centre bore 14 of above-mentioned module, cover has its thickness to be less than the support set 15 of module thickness, so that rise outside the extruding of module thinning distortion and the slip of flexible link, and the thickness of support set is less than;
---two lageniform support wheels 7,8 in Asia with setting spacing are in same plane as shown in Figure 3, the axial plane be situated between is arranged with can the sub-calabash shaped compacted under wheel 16 of up-down adjustment, bending needs during to use bend pipe length longer further.
In such a configuration, flexible link selects its technological effect of steel wire of establishment better.
