Specific implementation mode
A kind of embodiment of inner bearing type school shape tooling of the utility model is described further below in conjunction with the accompanying drawings.
A kind of specific embodiment one of the inner bearing type school shape tooling of the utility model, as depicted in figs. 1 and 2, inner bearing type school
Shape tooling includes telescopic mandril and the jacking block at mandril both ends is arranged, and tool structure is simple.Mandril includes 1 He of first support bar
Second support bar 2, first support bar 1 and second support bar 2 are threadedly coupled with regulating part to realize the adjusting to mandril length, top
Pole length adjusts accurate.First support bar 1 and second support bar 2 are circular tube structure in the present embodiment, can mitigate school shape tooling
Weight, do not have to the additional support construction for increasing tooling, support to tooling may be implemented in the frictional force that tooling is fixed against casting.
In other embodiments, first support bar, second support bar can be set as other tubular structures such as square tube.First support bar 1 and
Threaded adjusting is carried out by regulating part between two supporting rods 2, the regulating part in the present embodiment is that internal thread adjusts sleeve 3, is adjusted
With convenient for disassembly and assembly, repeatable utilization rate height.The length of two supporting rods can be replaced when necessary to adjust the length of mandril, to adapt to
The demand of different casting.It should be noted that：The scale value for identifying corresponding support pole length is equipped on two supporting rods,
There is certain reference role during mandril length adjustment.The outside that internal thread adjusts sleeve 3 is equipped with and adjusts mandril length
The rotation stop fit structure for adjusting the cooperation of tool rotation stop, the rotation stop fit structure in the present embodiment is square structure, it is convenient in spiral shell
Line adjusts the processing of sleeve.When adjusting mandril length, adjusts tool card and on the square structure of interior threaded adjusting sleeve 3 and revolve
Turn adjusting of the realization of inner thread sleeve 3 to mandril length.
As shown in Fig. 2, the first jacking block 4 be equipped with first boss 6, the second jacking block 5 be equipped with second boss 7, in order to it is right
The supporting rod interior sidewall surface answered matches, and the first boss 6 and second boss 7 in the present embodiment are set as cylindrical, first boss 6
It inlays and connect with the interior sidewall surface of the first support bar 1 of circular tube structure；The second support bar 2 of second boss 7 and circular tube structure
Interior sidewall surface inlay connection.First jacking block 4 and the second jacking block 6 are connected by two boss with corresponding supporting rod, and jacking block is facilitated
Installation and change, can meet the needs of different shape casting additionally by jacking block of different shapes is replaced, increase school shape work
The versatility of dress.First jacking block 4 and the second jacking block 5 design with the shape using school shape face is consistent with the size after the shape of casting school, can be with
Avoid due to school shape in face of school shape caused by casting it is inaccurate, or even damage casting the phenomenon that.
The material of tooling is 45 steel in the present embodiment, and the intensity of 45 steel is high, and durability is good, and tooling service life is long, in addition
The steel pipe that two supporting rods can purchase existing specification using tube material is used as mandril, reduces the processing capacity to two supporting rods, drop
The cost of low tooling.For needing to coordinate the casting for adding hot sizing, the coefficient of thermal expansion of the tooling itself is small, is adopted at tooling assembly
With clearance fit, tooling can be heated with casting, and be not in the situation of tooling dismounting difficulty after heating.
A kind of tool body shaping process of the inner bearing type school shape tooling of the utility model：Select the steel pipe being of convenient length as top
Two supporting rods of bar, two supporting rods adjust sleeve 3 with internal thread and connect composition mandril, after selection or processing school shape face and school shape
Two consistent jacking blocks of casting correspond to the inner bearing type school shape tooling for inlaying and being connected to and forming the utility model on two supporting rods.School shape
Tooling is packed into tubular class or frame clsss and waits in the shaped cast part of school, with adjusting external square knot of the tool cover in interior threaded adjusting sleeve 3
Clamping on structure adjusts the adjusting mandril total length of sleeve 3 by screwing internal thread, school shape tooling total length is made to reach suitable dimension,
Stretching casting corrects shape casting, can obtain the substantial distance of mandril by the scale on supporting rod at this time, convenient in school shape
The adjusting of mandril length is carried out when workpiece other angles.After completing school shape on a direction of casting, tooling rotation one is unclamped
Fixed angle again carries out casting the swollen school shape of support of other direction, it should be noted that if the jacking block school shape face of tooling is enough
Greatly, it can only rotate primary or need not rotate the school shape that casting all directions can be completed in school shape angle.Needs are matched
The casting for adding hot sizing is closed, multiple toolings can be used and be gap-matched respectively with casting at casting different directions and position,
Then tooling with waiting for that school shaped cast part is heated, school shape of the tooling completion to casting is removed after heating in order.
