Abstract
The utility model relate to a kind of can solve self-elevating ocean platform lifting tooth roller box planet carrier adopt split forging after the brought stable working that is welded poor, service life is short, ineffective self-elevating ocean platform lifting tooth roller box planet carrier casting forming die, there are four pieces of wedge subsidies pin position, four, upper flange region and form movable block together with upper flange, movable block is embedded in core print round platform middle upper portion, four pins, main Feeding channel subsidy and cover on the core print of center with upper flange and lower flange join domain, core print and upper lower flange and center core print are integrated to combine and form.Advantage: owing to being monoblock cast structure, overcome in the course of work brought by being welded after forging molding and easily produce destructiveness, add stationarity during work, extend the service life of product, also reduce production cost simultaneously, improve operating efficiency, improve the reliability of product, there are wide market prospects.
Description
Technical field
The utility model relates to a kind of can solution after self-elevating ocean platform lifting tooth roller box planet carrier adopts split forging and is welded that brought stable working is poor, service life is short, ineffective self-elevating ocean platform lifting tooth roller box planet carrier casting forming die, belongs to steel-casting shaping mould manufacture field.
Background technology
External upper and lower two end flanges and pin three part are in design forged into blank respectively, and by welding after machined, last fine finishining is shaping.Its weak point: stable working is poor, service life is short, inefficiency.
Utility model content
Purpose of design: avoid the weak point in background technology, design a kind of large speed ratio, the super large moment of torsion self-elevating ocean platform lifting tooth roller box planet carrier casting steel casting shaping mould that adopt integral casting forming, solve that to adopt split forging molding to weld the operation brought again numerous and diverse, production cost is high, and pin and upper and lower Flange joint region use procedure simultaneously very easily produces the self-elevating ocean platform lifting tooth roller box planet carrier casting forming die of destruction.
Design: in order to realize above-mentioned purpose of design.In order to realize above-mentioned purpose of design.The key of the application is to solve and adopts integral cast steel cast mold to replace welded structure part after split forging molding, how to ensure that the entirety of steel-casting is fine and close and solve pin and upper and lower Flange joint regional stress concentrates the crack defect problem caused, the key of its casting forming die integral structure layout design is, four pieces of wedge shape subsidies are evenly distributed in upper flange circumferentially, and hemispherical riser feeding location is set at upper flange center, ensure that the harmony of riser feeding, simultaneously because rising head is away from the transition region of upper lower flange and four pins, avoid concentrating of shrinkage stress, this shaping mould integral structure layout not only achieves the feeding problem of shrinking and solidifying, also overcome shrinkage stress simultaneously and concentrate the crack defect problem brought.
Technical scheme: a kind of large speed ratio, super large torsion gearbox planet carrier steel-casting shaping mould, there are four pieces of wedge subsidies pin position, four, upper flange region and form movable block together with upper flange, movable block is embedded in core print round platform middle upper portion, four pins, main Feeding channel subsidy and cover on the core print of center with upper flange and lower flange join domain, core print and upper lower flange and center core print are integrated to combine and form.
The utility model is compared with background technology, owing to being monoblock cast structure, overcome in the course of work brought by being welded after forging molding and easily produce destructiveness, add stationarity during work, extend the service life of product, also reduce production cost simultaneously, improve operating efficiency, improve the reliability of product, there are wide market prospects.

Detailed description of the invention
Embodiment 1: with reference to accompanying drawing 1 to Fig. 3.A kind of large speed ratio, super large moment of torsion self-elevating ocean platform lifting tooth roller box planet carrier casting steel casting shaping mould, there are four pieces of wedge subsidies 4 pin 2 position, four, upper flange 1 region and form movable block together with upper flange 1, movable block is embedded in core print 7 round platform middle upper portion, four pins 2, main Feeding channel subsidy 5 and cover on center core print 6 with upper flange 1 and lower flange 3 join domain, core print 7 is integrated to combine with upper lower flange and center core print 6 and forms.Center core print 6 is up-small and down-big tapered cylinder.It is planet carrier steel-casting body part that Fig. 2 beats hatched parts, and the lattice that knit a net first part are Feeding channel part.
It is to be understood that: although above-described embodiment to be contrasted detailed text description to mentality of designing of the present invention; but these text descriptions; just the simple text of mentality of designing of the present invention is described; instead of the restriction to mentality of designing of the present invention; any do not exceed mentality of designing of the present invention combination, increase or amendment, all fall within the scope of protection of the present invention.
