Abstract
The utility model relates to an elbow reshaping mould made of steel plates. An upper concave die and a lower concave die of the mould are manufactured by vertically and symmetrically cutting a standard finished elbow product along an annular central surface of the elbow. The inner diameter of a beveled edge of the elbow for manufacturing the mould is approximately equal to the outer diameter of a beveled edge of a reshaping elbow. The upper concave die and the lower concave die are welded with a support rack made of steel plates. The support rack is a box formed by welding the steel plates, and is mainly formed by welding a top plate, side plates and support plates. A certain number of support plates which are uniformly distributed radially relative to the rotating center of the upper concave die and the lower concave die are arranged in the middle of the box, and semicircular grooves adaptive to the outer diameter of the elbow of the upper concave die and the lower concave die are cut in the middle of the support plates so as to be welded with the external circular surface of the elbow of the upper concave die and the lower concave die. The peripheries of the support plates are respectively welded with the top plate of the box. The overall structure of the mould is stable and has good rigidity, and force transmission is dispersed and uniform. The mould has the advantages of simple process, low cost and short manufacturing period. The reshaping mould is simple and practical, and is particularly suitable for nominal size 350-600I series elbows.
Description
Technical field
The utility model belongs to metallic plate in the International Classification of Patents, pipe or does not have the cutting processing field basically, specially refers to nominal dimension 350～600 steel plate systems the shaping mould of welding of elbow is made.
Background technology
Nominal dimension 350～600 elbows belong to the heavy caliber pipe fitting, are pressed into the semicircle elbow with steel plate earlier usually, the butt welding of two semicircle elbows are formed again.Geomery all has variation behind the elbow welding forming, needs to realize final dimensional accuracy and the form accuracy of elbow finished product through shaping process.Shaping is exactly the standard die cavity pressurization setting of the elbow welding finished product being put into mould.The elbow shaping mould adopts the foundry goods metalworking to process usually.The Mold Making cost is high, the cycle is long.
Summary of the invention
The utility model purpose is to solve the shaping technique difficult problem of nominal dimension 350～600 steel plate systems to welding of elbow.
Particular content is the elbow shaping mould that a kind of steel plate is made, and comprises the upper and lower die of standard elbow-making, box-type bracing frame that top board and side plate welding are processed and the gripper shoe in the middle of the bracing frame.
Described upper and lower die is to cut open along elbow circle ring center face vertical symmetry with the finished product elbow to process.
The used elbow of described upper and lower die is the standard elbow of nominal dimension 200～600 in GB/T12459-2005 " the steel butt welding seamless pipe " standard.
The steel plate materials of the elbow shaping mould that described steel plate is made is normal carbon steel plate or Fine Steel Casting iron plate or alloy-steel plate.
The steel plate materials thickness of the elbow shaping mould that described steel plate is made is 10～80 millimeters.
The elbow shaping mould that described steel plate is made; Be that the welding of upper and lower die and steel plate realizes support fixation and reinforcement; Be welded into open casing by top board and side plate; Add 3～12 gripper shoes of weldering in the middle of the casing, the upper and lower relatively die finished product of gripper shoe elbow circle ring center is radial five equilibrium and evenly arranges.
The firm good rigidly of steel plate system elbow shaping mould overall structure, the power transmission is uniformly dispersed.Technology is simple, with low cost, fabrication cycle short.Be specially adapted to of the making of nominal dimension 350～600 I series steel plate systems to the welding of elbow shaping mould.

The specific embodiment
With nominal dimension 500 I series elbow in the GB/T12459-2005 standard is example.This elbow groove place outside dimension is 508; The elbow groove place external diameter 530 of nominal dimension 500 II series pressure rating Sch30, nominal bore diameter 505 and I series elbow external diameter 508 are approaching, and scale error is in this elbow standard code margin of tolerance.Finished product elbow with nominal dimension 500 II series pressure rating Sch30 is cut open along the ring symmetrical centre, with the bracing frame of steel plate welding production finished product semicircle elbow.Bracing frame and finished product semicircle elbow assembly welding are accomplished the body making of nominal dimension 500I series elbow shaping mould.Again after last machine pressure testing through elbow finished size and SHAPE DETECTION are carried out suitable polishing finishing to shaping mould, the finished product elbow precision after shaping satisfies the corner dimension precision and the form accuracy requirement of standard code fully.
Often there are a kind of dimension series elbow groove internal diameter and another dimension series elbow groove external diameter to have approximately equalised relation in the corner dimension series.This relation is commonplace between the elbow I of the middle nominal dimension 350～600 of GB12459-2005 " steel butt welding seamless pipe ", the II series.Thereby has suitable promotional value with the process of the shaping mould of another series specification elbow of standard finished products elbow-making.
