Embodiment
The embodiment of the inner bearing type school shape frock of the present invention is described further below in conjunction with the accompanying drawings.
The specific embodiment one of the inner bearing type school shape frock of the present invention, as depicted in figs. 1 and 2, inner bearing type school shape frock bag Include telescopic push rod and be arranged on the jacking block at push rod both ends, tool structure is simple.Push rod supports including first support bar 1 and second Bar 2, first support bar 1 and second support bar 2 are threadedly coupled with regulating part to realize the regulation to push rod length, and push rod length is adjusted Section is accurate.First support bar 1 and second support bar 2 are circular tube structure in the present embodiment, can mitigate the weight of school shape frock, no With the supporting construction of extra increase frock, the frictional force that frock is fixed against casting can realize support to frock.In other realities Apply in example, first support bar, second support bar can be set to other tubular structures such as square tube.First support bar 1 and second support bar 2 Between threaded adjusting carried out by regulating part, the regulating part in the present embodiment be internal thread regulating sleeve 3, is adjusted and dismounting side Just, it is high to repeat utilization rate.The length of two support bars can be changed if necessary to adjust the length of push rod, to adapt to different casting Demand.It should be noted that:The scale value for identifying corresponding support pole length is equipped with two support bars, in push rod length There is certain reference role during regulation.The outside of internal thread regulating sleeve 3 is provided with the regulation work with adjusting push rod length Has the rotation stop fit structure that rotation stop coordinates, the rotation stop fit structure in the present embodiment is square structure, facilitates internal thread adjusting set The processing of cylinder.When adjusting push rod length, regulation tool card is on the square structure of interior threaded adjusting sleeve 3 and rotating female screw Sleeve 3 realizes the regulation to push rod length.
As shown in Fig. 2 the first jacking block 4 is provided with first boss 6, the second jacking block 5 is provided with second boss 7, in order to it is right The support bar interior sidewall surface answered is engaged, and the first boss 6 and second boss 7 in the present embodiment are set to cylinder, first boss 6 Inlay and be connected with the interior sidewall surface of the first support bar 1 of circular tube structure;Second boss 7 and the second support bar 2 of 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 support bar, facilitate jacking block Installation and change, can meet the needs of different shape casting additionally by jacking block of different shapes is changed, 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 because school shape is inaccurate in face of school shape caused by casting, or even the phenomenon of damage casting.
The material of frock is 45 steel in the present embodiment, and the intensity of 45 steel is high, and durability is good, frock service life length, in addition The steel pipe that two support bars can purchase existing specification using tube material is used as push rod, reduces the processing capacity to two support bars, drop The cost of low frock.For needing to coordinate the casting for adding hot sizing, the thermal coefficient of expansion of the frock in itself is small, is adopted at frock assembling Coordinated with gap, frock can be heated with casting, and be not in the situation of frock dismounting difficulty after heating.
The tool body shaping process of the inner bearing type school shape frock of the present invention:Select two as push rod of the steel pipe that is of convenient length Strut, two support bars are connected composition push rod with internal thread regulating sleeve 3, and selection or processing school shape face are consistent with the casting after the shape of school Two jacking blocks correspondingly inlay be connected to formed on two support bars the present invention inner bearing type school shape frock.School shape frock is loaded tubular Class or frame clsss are treated in the shaped cast part of school, with regulation tool cover clamping in the external square structure of interior threaded adjusting sleeve 3, are passed through Screw internal thread regulating sleeve 3 and adjust push rod total length, school shape frock total length is reached suitable dimension, stretching casting is to casting Correct shape, the substantial distance of push rod can be now obtained by the scale on support bar, it is convenient in school other angles of shape workpiece Carry out the regulation of push rod length.After completing school shape on a direction of casting, unclamp frock and rotate certain angle again to casting Part carries out the swollen school shape of support of other direction, it is necessary to which explanation, if the jacking block school shape face of frock is sufficiently large, can only rotate one It is secondary or school shape angle need not be rotated can complete the school shape of casting all directions.For needing to coordinate the casting for adding hot sizing Part, multiple frocks can be used respectively in casting different directions and opening position and casting using gap cooperation, then frock with treating School shaped cast part is heated, and removes school shape of the frock completion to casting after heating in order.
The specific embodiment two of the inner bearing type school shape frock of the present invention, the specific reality with the inner bearing type school shape frock of the present invention Apply example one to compare, differ only in:As shown in figure 3, adjusted for the push rod for connecting first support bar 11 and second support bar 12 Part is external screw thread regulating sleeve 13.
The specific embodiment three of the inner bearing type school shape frock of the present invention, the specific reality with the inner bearing type school shape frock of the present invention Apply example one to compare, differ only in:As shown in figure 4, first boss 26 is provided with the circular tube shaped hole inserted for first support bar 21, Inlay the interior sidewall surface for being connected to first boss 26, the structure phase of second boss 27 and first boss 26 in the top of first support bar 21 Together, the top of second support bar 2 is inlayed with the interior sidewall surface of second boss 27 and is connected.
The specific embodiment four of the inner bearing type school shape frock of the present invention, the specific reality with the inner bearing type school shape frock of the present invention Apply example one to compare, differ only in:As shown in figure 5, first support bar 31 is connected with second support bar 32 using hole latch structure.The One support bar 31 with the connection end of second support bar 32 at be provided with female thread structure, second support bar 32 with first support bar External thread structure, the external thread structure of second support bar 32 and the screw-internal thread fit of first support bar 31 are provided with 31 connection end Connection forms the hole pin connected construction of two support bars.
The specific embodiment five of the inner bearing type school shape frock of the present invention, the specific reality with the inner bearing type school shape frock of the present invention Apply example one to compare, differ only in:First support bar and the first jacking block, the second jacking block of second support bar are formed in one knot Structure, first support bar and the first jacking block, second support bar and the second jacking block can be interference fit, riveting etc. in other embodiments Non-disconnectable attachment structure.
In the other embodiment of the inner bearing type school shape frock of the present invention, the connection of jacking block and push rod can also use screw, The regulating parts such as rivet are attached;Scale value can be not provided with two support bars;Frock material can also use the structure with 45 steel The other materials of intensity and thermal coefficient of expansion relatively;Rotation stop fit structure other can facilitate realization to stop for hexgonal structure etc. Turn the rotation stop fit structure coordinated.
