Description
Technical field
The utility model relates to a kind of forging tools, is specifically related to a kind of annular forging piece production saddle support.
Background technology
At present, when adopting flat-die forging mode to produce annular forging piece or rolling ring base in technical field of forging, often adopt core axial hole machining mode (also known as saddle forging).For large forgings or the higher alloy forged piece of resistance of deformation, require that saddle support instrument used has higher intensity and resistance to impact.As shown in Figure 3, traditional saddle support weight is comparatively large, is arranged on anvil block, fixes by drift.Mandrel is placed on the top of saddle support, from middle part through ring base.Under the strike of upper hammer anvil, forging distortion, rotates under external force simultaneously, completes the radial growth of a cycle.Then taken out by saddle support, hammer anvil under anvil block is installed, lies in a horizontal plane in ring base on lower hammer anvil, carries out axial leveling.For less-deformable alloy hot forging, due to its narrow forging temperature, complete one week expanding after, temperature has been reduced to stops under forging temperature, needs to reheat just can carry out leveling operation afterwards.Waste energy resource consumption like this, reduce production efficiency, and time heating of many fire there is baneful influence to less-deformable alloy structure property.
Utility model content
The utility model provides a kind of annular forging piece production saddle support, avoid installation repeatedly, the dismounting of forging saddle support and lower hammer anvil in annular forging piece process, improve expanding and efficiency that is trimming, shorten activity time, and for the ring forging of differing heights, the adaptation can carrying out saddle support span regulates, and improves the security of operation.
The technical solution of the utility model is as follows:
A kind of annular forging piece production saddle support, comprise riser, support, horse leg, connecting bolt, nut one, spring, rotating shaft screw bolt and nut two, the quantity of described riser, support and horse leg is two, described saddle support is arranged on lower hammer anvil, two described riser symmetries are placed in the both sides of described lower hammer anvil, two described risers are linked together by described connecting bolt and nut one, and described spring is placed between described riser and described nut one; Described Bracket setting is in the outside of described riser, and described support is provided with locating hole, and the afterbody of described horse leg is provided with through hole one, and described rotating shaft screw bolt inserts described locating hole and described through hole one is connected with nut two, is installed on the bracket by described horse leg; The working head of described horse leg can be placed on the upper surface of described lower hammer anvil, also can open to both sides.
Described annular forging piece production saddle support, its preferred version is, described locating hole is divided into locating hole one and locating hole two, and described horse leg is arranged on described locating hole one place, and the spacing of the working head of two described horse legs is 100mm; Described horse leg is arranged on described locating hole two place, and the spacing of the working head of two described horse legs is 200mm.
Described annular forging piece production saddle support, its preferred version is, the working head upper end of described horse leg arranges groove, and the mandrel laying annular forging piece is placed in described groove.
Described annular forging piece production saddle support, its preferred version is, described support is provided with circular hole one, and described horse leg is provided with through hole two, and when described horse leg is opened to both sides, fixed pin shaft inserts described circular hole one and described through hole two is fixed described horse leg.
Described annular forging piece production saddle support, its preferred version is, described support is provided with circular hole two, and when described horse leg is opened to both sides, set bolt inserts described circular hole two and is connected with nut three, is located described horse leg.
The beneficial effects of the utility model:
1, adopt high efficiency saddle support of the present utility model, in forging annular forging piece process, operation is capable of circulation carries out for expanding and leveling, and saved process time, improve efficiency, forging quality obtains fine guarantee.
2, different according to annular forging piece height, horse leg is placed on different locating hole places and adaptation adjustment is carried out to span, improve the flexural loading state of mandrel, improve the security of mandrel life-span and operation.Carry out simply supported beam model simplification to mandrel, the cross section of moment of flexure maximum absolute value is dangerouse cross-section, and maximum tension stress appears at the neutral axis place in cross section, maximal bending moment place.The length of beam is longer, needs less at the situation lower stress of proof strength.Visible, the span between horse leg 4 is less, and safety coefficient is higher, and this is significantly for bearing the operating mode of hitting compared with HI high impact in flat-die forging.
3, during expanding operation under hammer action, two horse legs may have a little displacement to both sides, are pulled playback under the action of the spring.During flattening operation, two horse legs are overturn to both sides, and fixed with fixed pin shaft and set bolt, prevent making because of impact endurance test shock horse leg produce and rotate.

Detailed description of the invention
As shown in Figure 1, 2, a kind of annular forging piece production saddle support, comprise riser 1, support 5, horse leg 6, connecting bolt 2, nut 1, spring 4, rotating shaft screw bolt 7 and nut two, the quantity of riser 1, support 5 and horse leg 6 is two, described saddle support is arranged on lower hammer anvil 14, two riser 1 symmetries are placed in the both sides of lower hammer anvil 14, and two risers 1 are linked together by connecting bolt 2 and nut 1, and spring 4 is placed between riser 1 and nut 1; Support 5 is arranged on the outside of riser 1, support 5 is provided with locating hole 1 and locating hole two, the afterbody of horse leg 6 is provided with through hole one, and rotating shaft screw bolt 7 inserts locating hole two and through hole one and is connected with nut two and is arranged on support 5 by horse leg, and the spacing of the working head of two horse legs 6 is 200mm; The working head upper end of horse leg 6 arranges groove, and during work, mandrel 12 is placed in a groove; Support 5 is provided with circular hole one, and horse leg 6 is provided with through hole 2 11, and when horse leg 6 is opened to both sides, fixed pin shaft 8 inserts circular hole one and through hole 2 11 pairs of horse legs 6 are fixed; Support 5 is provided with circular hole two, and when horse leg 6 is opened to both sides, set bolt 9 inserts circular hole two and is connected with nut three, is located horse leg 6.
When utilizing above-mentioned saddle support to carry out expanding operation, lower hammer anvil 14 is arranged on the anvil block 15 of equipment, and horse leg 6 is placed on lower hammer anvil 14, and mandrel 12 is placed in the groove of horse leg 6 through ring base 16; Under the downward strike to ring base 16 of upper hammer anvil 13, ring base 16 local deformation, radial and axial metal flow, horse leg 6 to the left and right both sides has a little displacement, and upper hammer anvil 3 lifts, riser 1 and horse leg 6 playback under the effect of spring 9, and by manual operation, ring base 16 rotates certain angle, upper hammer, 13 hit downwards again, and ring base 16 continues distortion.Until the distortion Posterior circle completing a week is reciprocal, ring base 16 internal diameter, enlarged outside diameter, wall thickness reduces, and axial height also has grows up.
Carry out flattening operation subsequently, by horse leg 6 both sides upset to the left and right, spacing by the set bolt 9 on support 5, simultaneously fixed pin shaft 8 inserts circular hole one and through hole 2 11 pairs of horse legs 6 are fixed; Lain in a horizontal plane in by ring base 16 on lower hammer anvil 14, upper hammer anvil 13 moves downward, and hits, make it the height dimension reaching technical requirement to ring base 16 end face.
