Description
Technical field
This utility model belongs to a kind of tubular object extruding field, particularly relates to the school mouth device of the bigger bend pipe straight length of a kind of bore.
Background technology
Current pipeline is after initial processing, the mouth of pipe or straight length are that ellipticity has a certain distance from international standard scope, in order to ensure later stage welding quality, small-bore bend pipe and straight tube are all used and are manually beaten or the hydraulic pressure school mouth machine of little frock carries out school circle inside the mouth of pipe, and multi-directional rotation realizes, but for the bend pipe of heavy caliber diameter range 1220, owing to its bore is big, highly difficult control, and bend pipe is heavy, is difficulty with artificial and relevant tooling device operation.
Utility model content
The purpose of this utility model is in that to provide a kind of big diameter elbow school mouth frock, low cost of manufacture, and labor intensity is low, and school circle efficiency is high, time saving and energy saving.
The technical solution of the utility model is:
Big diameter elbow school mouth frock, including forcing press platform and work platforms, work platforms is provided with battery main switch, motor, fuel tank, battery main switch connects motor by power line, and motor is positioned on fuel tank, and fuel tank is connected to oil regulating valve by the first petroleum pipeline, oil regulating valve is connected to fuel delivery valve by the second petroleum pipeline, being provided with Pressure gauge and manually-operated gate in connecting tube, fuel delivery valve is connected to hydraulic cylinder oil nozzle by petroleum pipeline, and described hydraulic cylinder oil nozzle is arranged on the top of forcing press platform; Forcing press platform includes base, upper bracket, hydraulic column, mold and lower mold, the upper and lower side of hydraulic column is connected with upper bracket, base respectively, mold is connected to the downside of upper bracket, lower mold is connected on base, mold and lower mold are equipped with semicircular mold cavity, mold and lower mold are oppositely arranged, upper and lower mould all includes mold base and semicircular arcwall face, arcwall face constitutes semicircular mold cavity, the outside of arcwall face is provided with polylith gusset, is provided with cross-brace post between adjacent gusset.
The centrage of cross-brace post and the centerline parallel of arcwall face.
Cross-brace post is cylinder.
Cross-brace post is two.
This utility model adopts mold and lower mold, it is separately fixed on the upper lower platform of forcing press, upper/lower die is two semicircle shapes, when the red Large Diameter Pipeline bend pipe of burning is placed on downforce machine lower planes, when hydraulic pressure, oil pump control, mold from top to bottom forms a seamless circle with lower mold, change the oval present situation of bend pipe, this operates maximum benefit is safe, laborsaving, can efficiently guarantee mouth of pipe school circle quality, it is ensured that with other pipe fitting seamless welding in later stage welding process.

Detailed description of the invention
Such as Fig. 1, shown in 2, big diameter elbow school of the present utility model mouth frock, including forcing press platform 17 and work platforms 25, work platforms 25 is provided with battery main switch 1, motor 3, fuel tank 10, battery main switch 1 connects motor 3 by power line 2, motor 3 is positioned on fuel tank 10, fuel tank 10 is connected to oil regulating valve 5 by the first petroleum pipeline 4, oil regulating valve 5 is connected to fuel delivery valve 9 by the second petroleum pipeline 8, connecting tube 8 is provided with Pressure gauge 7 and manually-operated gate 6, fuel delivery valve 9 is connected to hydraulic cylinder oil nozzle 12 by petroleum pipeline 11, hydraulic cylinder oil nozzle 12 is arranged on the top of forcing press platform, forcing press platform 17 includes base 18, upper bracket 19, hydraulic column 16, mold 13 and lower mold 14, the upper and lower side of hydraulic column 16 is connected with upper bracket 19, base 18 respectively, mold 13 is connected to the downside of upper bracket 19, lower mold 14 is connected on base 18, mold 13 and lower mold 14 are equipped with semicircular mold cavity 22, mold 13 and lower mold 14 and are oppositely arranged.
As shown in Figure 3, mold 13 and lower mold 14 all include mold base 20, and the side of mold base 20 is provided with semicircular arcwall face 21, and arcwall face 21 constitutes semicircular mold cavity 22, the outside of arcwall face is provided with polylith gusset 23, is provided with cross-brace post 24 between adjacent gusset 23.
The centerline parallel of the centrage of cross-brace post 24 and arcwall face 21, cross-brace post 24 is cylinder, and cross-brace post 24 is two.
Principle: workbench is provided with battery main switch 1, motor 3 is connected by power line 2, motor 3 is arranged on fuel tank 10, make hydraulic oil pass through the first petroleum pipeline 4 by the effect of motor 3 and enter in oil regulating valve 5, by connecting tube 8, oil regulating valve 5 and fuel delivery valve 9 are linked together, connecting tube 8 has Pressure gauge 7 and manually-operated gate 6, controls the size of oil mass by regulating manually-operated gate 6 and show on Pressure gauge 7. Fuel delivery valve 9 and hydraulic cylinder oil nozzle 12 are linked together by petroleum pipeline 11, have forcing press platform 15 below oil nozzle, and mold 13 in semicircle and lower mold 14 up and down, compressed by hydraulic column 16 and collectively form a closed circle under the effect of hydraulic pressure. Hydraulic cylinder is thus made to define an organic whole with hydraulic column and fuel tank, thus constituting a complete heavy caliber school oral fluid compression mould.
In the course of the work, power supply 1 is worked by power line 2 drive motor 3, hydraulic oil enters oil regulating valve by petroleum pipeline 4 from fuel tank 10, manually valve 7 regulates in pressure entrance fuel delivery valve 9, and enter hydraulic cylinder oil nozzle 12 by oil pipe 11, pressure-driven hydraulic column 16, when burning red heavy caliber straight length and being placed in lower mold 14, makes lower half circle mould 13 and 14 form a closed circle, makes non-round pipe end reach the state of school circle by the effect of mould.
