Abstract
The utility model relates to an upsetting die for machining, which is characterized in that a taper cavity (5) is produced at a position where an upper die (4) and a workpiece (1) are contacted. A die conical surface (6) of the taper cavity (5) is matched with a workpiece conical surface (3), and upsetting can be carried out to some prescribed position of a seamless steel pipe by that the die conical surface (6) of the taper cavity (5) is used. When an upsetting deformation zone is 6 times larger than the thickness of a pipe wall or even more, the phenomena of folding and bending can still not be generated, and accordingly, the utilization of metal materials is improved, workpiece intensity is improved, and cost is reduced.
Description
The utility model relates to the mould of machining, especially the mould of jumping-up processing usefulness.
At present, the mould of known jumping-up processing usefulness, it contacts upsetting pressure with the workpiece end face position is a plane body, this in practice mould is during to the seamless steel pipe jumping-up, when the jumping-up deformed area more than one times under the situation, can occur longitudinal folding, the buckling phenomenon of tube wall greater than thickness of steel pipe, can not be shaped.
The purpose of this utility model is to provide a kind of heading die, utilizes it to carry out jumping-up to a certain desired location of seamless steel pipe, when the jumping-up deformed area still can not produce folding, buckling phenomenon during greater than 6 times of thicknesss of pipe wall.
The purpose of this utility model is achieved in that the position that mould contacts with workpiece is made into the taper cavity.The conical surface of mould taper cavity can form the normal component of force of the conical surface when contacting pressurized with the workpiece conical surface, this normal component of force can be resisted tube wall because of pressurized folds, crooked trend, makes metal to the position development of setting jumping-up, is full of die cavity, natural moulding.
Adopt technique scheme, can carry out jumping-up to a certain desired location of seamless steel pipe, when the jumping-up deformed area greater than 6 times of thickness of steel pipe, even more for a long time, still can not produce folding, buckling phenomenon, make it to reach the good effect that improves the metal material utilization rate and improve workpiece strength and reduce cost.
Below in conjunction with drawings and Examples the utility model is further specified.
Figure of description is the utility model structure cutaway view and jumping-up moulding work status cutaway view.Figure of description also is a Figure of abstract.
Among the figure, the 1. workpiece 2. upset position 3. workpiece conical surfaces 4. patrixes 5. taper cavitys 6. mould conical surfaces 7. counterdies
With reference to the accompanying drawings, the utility model is a kind of heading die, it is characterized in that the position that patrix (4) contacts with workpiece (1) is made into taper cavity (5).With the seamless steel pipe is that raw material making mud slurry pump cylinder jacket is an example, after the seamless steel pipe blanking, one end is processed into the workpiece that has tapering, be called workpiece (1), the conical surface of this workpiece (1) is the workpiece conical surface (3), according to the jumping-up needs, setting upset position (2) and following some length thereof of workpiece (1) are the jumping-up deformed area, and this jumping-up deformed area also is the thermal treatment zone.In process of production, the mould conical surface (6) is consistent with the workpiece conical surface (3), match, when the mould conical surface (6) of patrix (4) to the workpiece conical surface (3) when pressure is arranged, the conical surface normal component of force that forms can be resisted folding, the crooked trend of wall compression, make the metal in the deformed area be full of die cavity, promptly be full of upset position (2).Through practice, when the jumping-up deformed area greater than 6 times of thickness of steel pipe, even more for a long time, still can not produce folding, buckling phenomenon.Heading die comprises patrix (4) and counterdie (7), and the position that patrix (4), counterdie (7) and workpiece (1) contact all can be made into taper cavity (5), can reach good effect of the present utility model equally.
Claims (1)
1. a heading die is characterized in that the position that patrix (4) contacts with workpiece (1) is made into taper cavity (5).
