Solution is replaced, and has not only improved replacement efficiency, but also can reduce the cost of gear die.And its is simple in structure, easy to use, each component
Between seamless applying design can also ensure the precision of Gear Processing.
Further, for ease of processing, demoulding, the tooth form bore dia of upper toothed member is straight more than the scallop of lower toothed part
Footpath.
Further, to improve the machining accuracy of binodal gear, the lower toothed part and upper toothed member are that wire cutting adds
Work forms.And wire cutting technology is ripe, easy to process, easy to be reprocessed to single toothed member, and also allow for pair
Toothed member carries out trickle adjustment, to improve precision.
Further, fastening bolt or holding pin are equipped between the base two and upper toothed member the two is coaxial fixed.
In said structure, it can prevent sidesway or slip from reducing the concentricity of mould, be further ensured that the concentricity of all parts, at the same time
Ensure that gear has certain accuracy in process.
Further, the base two, the upper surface of base one are horizontal plane, corresponding upper toothed member, lower toothed part
Bottom surface be also horizontal plane, and the height of base two is no more than the height of base one.Said structure is easy to each combination section of aliging
Part, is conducive to replace, assembles toothed member again, ensure the machining accuracy of gear in the case where replacing toothed member.
Further, it is to improve the degree of modularity, the outer wall of the lower toothed part is flushed with the outer wall of base one, upper tooth form
The lateral wall of part is flushed with the outer wall of base two.
Preferably, for ease of the upper toothed member and lower toothed part of aliging, ensure final product quality, the top of the base two is not
More than the top of base one.
Preferably, to prevent from loosening between lower toothed part and base one, influence final finished quality, the base two with
Fastening bolt is equipped between upper toothed member or holding pin coaxially fixes the two, the top of fastening bolt is less than lower toothed part top
Or flushed with the top of lower toothed part.
Beneficial effects of the present invention are as follows：In the present invention, by the teeth molded part that half uses be split as upper toothed member with
Lower toothed part, upper toothed member are respectively adopted line with lower toothed part and cut machine-shaping, can improve the precision of forming gear.Upper tooth form
Part, lower toothed part also allow for replacing various sizes of toothed member to process various sizes of gear, without gear die is overall
Replacement is disassembled, reduces adjustment, the cost for replacing gear size and man-hour, and its is easy to assembly, quick.
In brief, can be in process the present invention provides a kind of box-like Double-gear organisation of working of improvement group
Preferably ensure the precision and concentricity of gear forming part, and reduce the cost of secondary operation and the man-hour expended, the letter of its structure
Single, manufacture cost is low, is easy to use suitable for gear and other parts mould processing occasion.
