The utility model discloses dismantlement equipment that can be convenient is applicable to the disposable wind spring processing of convexity type spring, and the convexity type spring mechanical properties after the processing is good, and machining efficiency is high, and the last through -hole of die can alleviate the weight of die and whole mould, has improved machining precision and processingquality.
Description
Technical field
The utility model belongs to a kind of spring and manufactures mould and in particular to easy-disassembling-assembling middle convex floating die assembly.
Background technology
Convexity spring is the spring that a kind of middle part outer annular diameter is more than both sides outer annular diameter, due to the particularity of its structure,
After the completion of causing wind spring, floating die assembly can not take out, so adopt prior art first making two tower-like springs respectively more, then
The mode of production welded, reduces production efficiency, simultaneously because the volume of floating die assembly is substantially equal to spring inner ring being enclosed
Become the volume in space, so the general volume of mould being used is larger, more heavy, not only increase the cost of mould, and
Increased the physical load of employee when spring manufactures, reduce further production efficiency.
Chinese patent cn203470755u proposes a kind of camber floating die assembly, but it is gone back in installing production process
There are some problems.
Content of the invention
The utility model is to solve the problems, such as that prior art proposes, and its objective is to provide easy-disassembling-assembling middle convex
Floating die assembly.
The technical solution of the utility model is: easy-disassembling-assembling middle convex floating die assembly, and including base plate, base plate one end is arranged
There is connecting shaft, connecting shaft forms multiple assembling collars, the assembling cylindrical place of collar is provided with matrix, shape between two neighboring matrix
Become transition gap, matrix is more than the disk-like structure of axial length for radius, matrix is centrally formed shoulder hole, the big footpath section of shoulder hole
With the cylindrical interference fit of assembling collar, the path section restriction matrix axial movement direction of shoulder hole, shape on connecting shaft free end
Become external screw thread, the external screw thread of described connecting shaft is matched with the locking nut of locking matrix, and the outside diameter of matrix is by connecting shaft
Centre be sequentially reduced to the both sides of connecting shaft.
The pin-and-hole being connected with big footpath section is formed on the path section of shoulder hole, the alignment pin being arranged in pin-and-hole is inserted into dress
Join in the location hole of collar.
Described base plate is welding or mode connects for screw with the connected mode of connecting shaft.
It is evenly equipped with multiple through holes along axis on described matrix end face.
Described through hole is circular hole, elliptical aperture.
The utility model can easily dismantle assembling it is adaptable to the disposable wind spring of middle convex spring is processed, after processing
Middle convex spring mechanical performance good, high in machining efficiency, the utility model can be by from different length and be provided with difference
Quantity assembles the connecting shaft of collar, and the system completing convex spring in all size using the matrix of different-diameter and quantity
Make, the through hole on matrix can mitigate matrix and the weight of whole mould, improve machining accuracy and crudy.
Brief description

Specific embodiment
Hereinafter, with embodiment, the utility model is described in detail referring to the drawings:
It is easy to the middle convex floating die assembly of dismounting as shown in Fig. 1 ~ 3, including base plate 1, base plate 1 one end is provided with connecting shaft
5, connecting shaft 5 forms multiple assembling collars 8, the assembling cylindrical place of collar 8 is provided with matrix 2, two neighboring matrix 27.
Described through hole 7 is circular hole, elliptical aperture.The weight of matrix 2 can be mitigated, be further able to mitigate whole mould
Weight.
The course of work of the present utility model is as follows:
Matrix 2 is sleeved in the assembling collar 8 of connecting shaft 5 in order, by alignment pin, matrix 2 is positioned,
Then axially position is carried out by locking nut 4, mounted mould is placed on spring coiling machine and carries out wind spring.
After wind spring finishes, whole mould is taken off from spring coiling machine, unclamp locking nut 4, alignment pin, by base plate 1
Movement makes base plate 1, matrix 2 separate, and matrix 2 is taken out from the gap of spring, completes the wind spring process of middle convex spring.
The utility model can easily dismantle assembling it is adaptable to the disposable wind spring of middle convex spring is processed, after processing
Middle convex spring mechanical performance good, high in machining efficiency, the utility model can be by from different length and be provided with difference
Quantity assembles the connecting shaft of collar, and the system completing convex spring in all size using the matrix of different-diameter and quantity
Make, the through hole on matrix can mitigate matrix and the weight of whole mould, improve machining accuracy and crudy.
