Abstract
The utility model discloses an one (b) plants pipe type bloated shape device of many bosss in side, belongs to tub bloated shape technical field of a class side boss. Quality material cost poor, that outer tube class side boss exists that current pipe fitting shaping rear surface exists is high, the bigger scheduling problem of fillet of side boss and the existence of pipe fitting junction. The utility model discloses a bulging die, branch are located two sets of actuating mechanism of bulging die both sides and are used for the fashioned bloated shape inner core of pipe fitting, offer the die cavity that can hold the work piece on the bulging die, and the shape inner core that expands is set and is placed in the work piece, and two sets of actuating mechanism separately -driven push the inner core that appears that expands, make the pipe fitting take place plastic deformation and reach required shape. The utility model discloses a core that expands takes shape, compares with cast form, can overcome the manufacturing cost height, a great deal of difficult problem of surface quality subalternation. The utility model has the advantages of simple structure, with low costs, pipe fitting outward appearance edges and corners are clearly demarcated, the depth is unanimous, the homogeneity is good.
Description
Technical field
The utility model belongs to boss Bulging Technology field, tubing side, especially relevant with a kind of tubing side many boss bulging device.
Background technology
At present, domestic and international tubing side boss adopts forging type mostly, and this mode has many defects: one is that formation of tubes rear surface mass ratio is poor; Two is that material cost is higher; Three is side boss larger with pipe fitting joint fillet (R > 3), corner angle fuzzy.And existing casting device complex structure, safeguard inconvenient, cost is also high.
Utility model content
The problems such as the fillet that the material cost that of poor quality, the outer tubing side boss that the purpose of this utility model is intended to overcome the existence of existing formation of tubes rear surface exists is high, side boss exists with pipe fitting joint is larger, provide tubing side many boss bulging device that a kind of structure is simple, cost is low, pipe fitting outward appearance corner angle clearly demarcated, depth consistent and uniform is good.
For this reason, the utility model is by the following technical solutions: tubing side many boss bulging device, comprise bulging die, be divided into two groups of driving mechanisms of bulging die both sides and the bulging inner core for formation of tubes, bulging die offers the die cavity that can hold workpiece, bulging inner core puts into inside workpiece, workpiece is positioned in bulging die die cavity, and the driving mechanism described in two groups drives Extrusion bulging inner core respectively, makes pipe fitting generation plastic deformation and reaches required shape.
As to technique scheme supplement and perfect, the utility model also comprises following technical characteristic.
Described driving mechanism is hydraulic drive mechanism, and hydraulic drive mechanism comprises oil cylinder and piston rod, and piston rod and described bulging inner core are conflicted.
The both sides of described bulging die are provided with the draw-in groove that can hold described cylinder block, and described oil cylinder is installed on this draw-in groove.
The periphery, cylinder body front end of described oil cylinder forms integral type block, the draw-in groove of described bulging die offers the block groove of setting for block.
Described piston rod is resetted by return spring.
Described tubing side many boss bulging device also comprises pressure distributor, and pressure distributor offers two joints and an inlet union be connected with hydraulic power source that are connected with two described oil cylinders by hydraulic tube, thus realizes fuel feeding by unified hydraulic power source.
Described bulging inner core comprises soft core and two hard cores, and hard core is divided into soft core two ends.
Described soft core is that polyurethane materials making is shaping.
Use the utility model can reach following beneficial effect: the utility model is shaped by bulging core, compared with cast form, can overcome manufacturing cost high, many difficult problems such as surface quality difference.The utility model has the advantages such as structure is simple, cost is low, pipe fitting outward appearance corner angle clearly demarcated, depth consistent and uniform is good.The utility model is applicable at the tubing of uniform wall thickness, threeway, four-way class part forming.
Accompanying drawing explanation
Fig. 1 is that modular construction of the present utility model splits schematic diagram.
Fig. 2 is the lower die structure schematic diagram of bulging die.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
Embodiment: as shown in Fig. 1 ~ Fig. 2, the utility model comprises bulging die 1, is divided into two groups of driving mechanisms 2 of bulging die 1 both sides and the bulging inner core 3 for formation of tubes, bulging die (upper and lower mould symmetry is manufactured) is installed on hydraulic press workbench face, bulging die 1 offers the die cavity that can hold workpiece, bulging inner core 3 puts into inside workpiece, and workpiece is positioned in bulging die 1 die cavity; Driving mechanism 2 drives Extrusion bulging inner core 3, makes pipe fitting generation plastic deformation and reaches required shape.
As preferably, driving mechanism 2 is hydraulic drive mechanism, and hydraulic drive mechanism comprises oil cylinder 4 and piston rod 5, and piston rod 5 and bulging inner core 3 are conflicted.
Further, the both sides of bulging die 1 are provided with the draw-in groove that can hold oil cylinder 4, and oil cylinder 4 is installed on this draw-in groove, and periphery, oil cylinder 4 front end forms integral type block 7, the draw-in groove of bulging die 1 offers the block groove of setting for block 7.
Preferably, piston rod 5 is resetted by return spring 8.
Further, tubing side many boss bulging device also comprises pressure distributor 6, pressure distributor 6 offers two joints and an inlet union be connected with hydraulic power source that are connected with two oil cylinders 4 by hydraulic tube, thus realizes fuel feeding by unified hydraulic power source.Pressure distributor is installed on hydraulic pressure owner hydraulic tube annex and is connected with hydraulic pressure owner hydraulic tube, by the pressure distribution in main hydraulic tube to hydraulic jack by high-pressure oil pipe.
As preferably, bulging inner core 3 comprises soft core 9 and two hard cores 10, and hard core 10 is divided into soft core 9 two ends, and soft core 9 makes shaping for polyurethane materials.
Utility model works principle: oil cylinder 4 is installed in the draw-in groove on bulging die 1, and be connected with pressure distributor by high-pressure oil pipe, the hydraulic coupling piston rod 5 Extrusion bulging inner core 3 distributed by pressure distributor, make pipe fitting generation plastic deformation and reach required shape, hydraulic press pressure release after hydraulic coupling keeps certain hour, return spring 8 on hydraulic drive mechanism pulls piston rod 5, makes it get back to initial position.
