Abstract
The utility model discloses thick mould assembly of circular steel tube includes stamping die in thick shaping bed die and two the thick shaping, slightly the upper surface of shaping bed die is the upwards opposite W shape that goes up the bending in outstanding, both ends of arc form for mid portion, two the stamping die symmetry sets up in the thick shaping the top at thick shaping bed die both ends, stamping die's bottom is outstanding arc form downwards in the thick shaping, in the thick shaping stamping die the bottom dorsad the radius of the cambered surface of thick shaping bed die upper surface tip be greater than towards the radius of the cambered surface of thick shaping bed die upper surface tip. The utility model has the advantages of the shaping is steady, the shaping is regular, steel tube strength is high, the modulus is big.
Description
Technical field
The utility model relates to round steel pipe processing unit (plant), particularly relates to the thick mould assembly of round steel pipe.
Background technology
Round steel pipe refers to both ends open and has hollow concentric circles section, the larger steel of its length and periphery.
The technological process of round steel pipe processing comprise band steel inspection, shearing, scale, sizing, weld, polish (seamless process), scale, inspection.Ф 76 steel pipe is widely used in pipeline, Thermal Equipment, mechanical industry, the petroleum geology probing field such as container, chemical industry.
Steel band especially in the sizing stage, will be with steel by multiple kinds of molds, in the effect machine-shaping successively of each mould shape in process usually.With steel after traditional mould shape, its intensity, modulus damage are larger.
Utility model content
The utility model, for the deficiencies in the prior art, provides shaping steady, the thick mould assembly of shaping regular, that steel strength is high, modulus is large round steel pipe.
The utility model is solved the problems of the technologies described above by following technological means: the thick mould assembly of round steel pipe, comprises thick molding bottom die and two thick shaping upper diels; The upper surface of described thick molding bottom die is the W shape that the curved shape of mid portion projects upwards, two ends are bent upwards relatively; Two described thick shaping upper diels are symmetricly set on the top at described thick molding bottom die two ends, and the bottom of described thick shaping upper diel is arc shape outstanding downwards; The radius of the bottom of the described thick shaping upper diel cambered surface of described thick molding bottom die upper surface end is dorsad greater than the radius of the cambered surface towards described thick molding bottom die upper surface end.
Preferably: the radius of the bottom of the described thick shaping upper diel cambered surface of described thick molding bottom die upper surface end is dorsad 34.4mm, radian is 90 °, described thick shaping upper diel bottom faces to the radius of the cambered surface of described thick molding bottom die upper surface end be 32.4mm, radian is 90 °;
The radian of the upper surface mid portion cambered surface of described thick molding bottom die is 26 °, and its radius is 326.97mm, and the radius of the cambered surface at the upper surface two ends of described thick molding bottom die is 38.4mm, radian is 90 °.
Preferably: the described thick shaping top of upper diel is connected with the telescopic end of hydraulic cylinder.
Preferably: the stiff end of described hydraulic cylinder is arranged in frame.
The utility model has the advantage of:
(1) before carrying out cans, carry out pre-crimped by thick mould, the two ends of steel band are formed by the downward punching press of thick shaping upper diel of correspondence the arc shape be bent upwards, is convenient to the processing of postorder mould.
(2) use hydraulic cylinder to drive upper diel to press down, realize the adjustability of spacing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the thick mould assembly of the utility model round steel pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, the open thick mould assembly of round steel pipe of the present embodiment, comprises thick molding bottom die 11 and two thick shaping upper diels 12; The upper surface of described thick molding bottom die 11 is the W shape that the curved shape of mid portion projects upwards, two ends are bent upwards relatively.Two thick shaping upper diels 12 are symmetricly set on the top at thick molding bottom die 11 two ends, and the bottom of thick shaping upper diel 12 is arc shape outstanding downwards.
To process the thick mould assembly that model is Ф 76 steel pipe, the radius of the bottom of thick shaping upper diel 12 cambered surface of thick molding bottom die 11 upper surface end is dorsad 34.4mm, radian is 90 °, the bottom faces of thick shaping upper diel 12 to the radius of the cambered surface of thick molding bottom die 11 upper surface end be 32.4mm, radian is 90 °.
The radian of the cambered surface of the upper surface mid portion of thick molding bottom die 11 is 26 °, and its radius is 326.97mm, and the radius of the cambered surface at two ends is 38.4mm, radian is 90 °.
The top of thick shaping upper diel 12 is connected with the telescopic end of hydraulic cylinder (not shown in FIG.), and the stiff end of hydraulic cylinder is arranged in frame (not shown in FIG.).
The foregoing is only the preferred embodiment that the utility model is created; do not create in order to limit the utility model; the any amendment done within all spirit of creating at the utility model and principle, equivalent to replace and improvement etc., all should be included within protection domain that the utility model creates.
