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.
