Abstract
The invention relates to a hydraulic forming mould for stretching a pipe fitting at a vertical angle, which can effectively solve the problem of being incapable of forming by adopting an ordinary punching mould, and has the advantages of simple structure and high machining efficiency. The technical scheme is as follows: the hydraulic forming mould comprises an upper template and a lower template, wherein a forming concave die is installed on the lower template, and backers are installed around the forming concave die; and the hydraulic forming mould is characterized in that: a hydraulic cylinder is installed at the lower part of the upper template, and a piston rod of the hydraulic cylinder is fixedly connected with the upper template.
Description
Technical field
The present invention relates to punched pipefitting process unit field, be specially the shaped by fluid pressure mould that is used for the stretching of pipe fitting vertical angle.
Background technology
A kind of pipe fitting that is used for automobile exhaust system, it is vertical that its air inlet axis and gas outlet axis are 90 degree, adopt common diel and pressing equipment, because its forming convax mould or molding concave die can not be done the translation of horizontal direction, so can't carry out processing and forming to it; Also have at present by repacking forming convax mould or molding concave die into fixing and movable split type combining structure; movable structure can be along the horizontal plane translation when patrix and counterdie matched moulds thereby reach; reach purpose with formation of tubes, but its complex structure, and working (machining) efficiency is low.
Summary of the invention
At the problems referred to above, the invention provides and be used for the shaped by fluid pressure mould that the pipe fitting vertical angle stretches, it can effectively solve and adopt the problem that common diel can't moulding, and is simple in structure, the working (machining) efficiency height.
Its technical scheme is such, it comprises cope match-plate pattern and lower bolster, on the described lower bolster molding concave die is installed, and the backer is installed around the described molding concave die, it is characterized in that: described cope match-plate pattern bottom is equipped with hydraulic cylinder, and the piston rod of described hydraulic cylinder and described cope match-plate pattern are connected and fixed.
The shaped by fluid pressure mould that is used for the stretching of pipe fitting vertical angle of the present invention, it is simple in structure, it uses hydraulic pressure that pipe fitting is carried out punching press, in forming process, hydraulic pressure plays the effect of forming convax mould, and with the punched pipefitting moulding, its processing can not be subjected to the influence of formation of tubes shape requirement with molding concave die, the formed precision height, the working (machining) efficiency height.
Description of drawings
Fig. 1 is the shaped by fluid pressure mould structure schematic diagram that is used for the stretching of pipe fitting vertical angle of the present invention.
The specific embodiment
See Fig. 1, mould structure of the present invention comprises cope match-plate pattern 1 and lower bolster 2, and molding concave die 3 is installed on the lower bolster 2, around the molding concave die 3 backer 4 is installed, and cope match-plate pattern 1 bottom is equipped with hydraulic cylinder 5, and the piston rod 6 and the cope match-plate pattern 1 of hydraulic cylinder 5 are connected and fixed.When using shaped by fluid pressure Mould Machining pipe fitting of the present invention, earlier pipe fitting to be processed is rotated in the die cavity of molding concave die 3, it is right then hydraulic cylinder 5 usefulness screws 7 to be fixed on the molding concave die 3, and piston rod 6 is descending then, and the hydraulic oil that promotes in the hydraulic cylinder 5 carries out punch forming to pipe fitting.Among Fig. 1,8 is sealing ring.
Claims (1)
1. be used for the shaped by fluid pressure mould that the pipe fitting vertical angle stretches, it comprises cope match-plate pattern and lower bolster, on the described lower bolster molding concave die is installed, the backer is installed around the described molding concave die, it is characterized in that: described cope match-plate pattern bottom is equipped with hydraulic cylinder, and the piston rod of described hydraulic cylinder and described cope match-plate pattern are connected and fixed.
