Description
Technical field
The utility model relates to steel pipe shaping field, particularly a kind of steel tube inner hole apparatus for shaping.
Background technology
Suck back oil connection and have good interchangeability, economy at engineering Hydraulic Industry, applicability is strong and be widely used.But product has following shortcoming:
1, sucking back the steel pipe parts of pipe pipe joint when carrying out bent tube technique, can there is certain flat ratio in steel pipe, viewed from profile flange and the transition of steel tube inner hole junction unsmooth, certain limit can affect the current state of fluid; 2, pipe joint needs to carry out assembling spot welding before carrying out soldering, and because steel pipe exists flat ratio, during soldering, some scopes of steel pipe too much can flow out weld seam because of pricker liquid, sagging phenomenon is formed in non brazing district, affect product attractive in appearance, can product quality be affected under serious conditions, cause product rejection.
Utility model content
The utility model is flat for producing when solving steel pipe parts bend pipe, unsmooth with transition during Flange joint, during erection welding, owing to there is flat road rate, pricker liquid flows out weld seam, forms sagging phenomenon in non brazing district, affect product attractive in appearance, can product quality be affected under serious conditions, cause product rejection.
The utility model proposes a kind of steel tube inner hole apparatus for shaping, comprise workbench, hydraulic jack, be installed on described hydraulic jack output connecting rod, two be inverted in wedge on described workbench, be installed on the sizing die of described connecting rod end, described hydraulic jack is positioned at below described workbench, described workbench is provided with through hole, described connecting rod stretches out described workbench by described through hole, described sizing die is inverted round platform, and the one side that described round platform is less is fixed with described connecting rod; Described wedge is close to described sizing die both sides.
Further preferred version of the present utility model, the wedge inwall being affixed on described sizing die both sides is inclined-plane, fits in the side of described wedge inwall and described sizing die.
Further preferred version of the present utility model, the end face of described sizing die is greater than described through hole.
Further preferred version of the present utility model, described wedge outer wall is arc.
Described connecting rod is through the through hole of described workbench, described sizing die is positioned at above workbench, two wedges are inverted and are close to described sizing die both sides, steel pipe to be processed is placed on described wedge outer wall, during hydraulic jack retracted downward, described sizing die applies pressure to described wedge inwall, and wedge is expanded to both sides, pressure is applied to the inwall of steel pipe, realizes the effect of steel pipe shaping.
The steel tube inner hole apparatus for shaping that the utility model proposes, the pulling force of hydraulic jack acts on wedge type block frock inwall, and wedge type block is expanded outwardly, and the wall contacts of wedge type block is in steel pipe inner wall, the pulling force of oil cylinder acts on steel pipe inner wall, makes steel pipe expand the effect having reached inwall shaping.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
View when Fig. 2 is processing steel pipe of the present utility model;
1-hydraulic jack, 2-connecting rod, 3-workbench, 4-wedge, 5-sizing die, 6-through hole, 7-wedge outer wall, 8-wedge inwall, 9-steel pipe.
Detailed description of the invention
The utility model is described in detail, illustrative examples wherein and illustrate and be only used for explaining the utility model below in conjunction with accompanying drawing and specific embodiment, but not as to restriction of the present utility model.
As shown in Figure 1, a kind of steel tube inner hole apparatus for shaping, comprise workbench 3, hydraulic jack 1, the connecting rod 2, two that is installed on described hydraulic jack 1 output are inverted in wedge 4 on described workbench 3, be installed on the sizing die 5 of described connecting rod 2 end, described hydraulic jack 1 is positioned at below described workbench 3, described workbench is provided with through hole 6, described connecting rod 2 stretches out described workbench 3 by described through hole 6, described sizing die 5 is inverted round platform, and the one side that described round platform is less is fixed with described connecting rod 2; Described wedge 4 is close to described sizing die 5 both sides.
As Fig. 2, described connecting rod 2 is through the through hole 6 of described workbench 3, described sizing die 5 is positioned at above workbench 3, two wedges 4 are inverted and are close to described sizing die 5 both sides, and steel pipe 9 to be processed is placed on described wedge outer wall 7, during hydraulic jack 1 retracted downward, described sizing die 5 applies pressure to described wedge inwall 8, make wedge 4 to both sides expansion, pressure is applied to the inwall of steel pipe 9, realizes the effect of steel pipe 9 shaping.
Further preferred version of the present utility model, the wedge inwall 8 being affixed on described sizing die 5 both sides is inclined-plane, and described wedge inwall 8 is fitted with the side of described sizing die 5.
Further preferred version of the present utility model, the end face of described sizing die 5 is greater than described through hole 6, does not add man-hour sizing die and 5 can be positioned on workbench 3, prevent from dropping below workbench 3, use inconvenience.
Further preferred version of the present utility model, described wedge outer wall 7 is arc, and wedge outer wall 7 is identical with the inwall radian of described steel pipe 9, has better shaping effect to steel pipe 9, prevents the scratch to steel pipe 9 inwall.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
