Abstract
The utility model discloses a kind of steel tire rim extension die, is made of upper plate, lower plate, cone, expansion block, feather key and spring ring；Cone is fixedly connected on upper plate bottom surface by screw；10 feather keys are disposed radially and circumference uniform distribution is on lower plate, each feather key is fixedly connected by two positioning pins and two screws with lower plate, 10 expansion blocks are corresponded with 10 feather keys and each expansion block is radially slidably connected with corresponding feather key, expand block and be equipped with the conical surface coordinated with cone taper, and expand and oil guide groove is provided between block and cone in favor of lubrication；Expansion block is having spring ring recess at upper and lower ends, and spring ring is in spring ring recess.It can ensure the molding surface size requirement of wheel rim body very well, and apparatus structure is simple, it is easy to operate.
Description
Technical field
It the utility model is related to a kind of dilatation mold, and in particular to a kind of steel wheel rim body extension module.
Background technology
At present, steel wheel rim process of expansion is the committed step for making wheel rim reach molding surface size requirement, in this process
Dilatation mold plays key effect, and dilatation mold directly influences the key technologies such as cylindricity and the radial run-out of wheel rim
Parameter, is directly linked to the technical quality of wheel rim.
The existing most workpiece loading and unloading of dilatation mold is difficult, and is not easy size needed for product after adjustment expansion, and it is strong to work
Spend larger.
The content of the invention
The utility model provides a kind of steel wheel rim body extension module, it is the simple dilatation mold with multiple expansion blocks,
So as to reach the expansion requirement of steel wheel rim body.
The technical scheme adopted by the utility model is that：
A kind of steel tire rim extension die, is made of upper plate, lower plate, cone, expanding mechanism and spring ring；Cone
It is fixedly connected on upper plate bottom surface；Expanding mechanism is slidably connected with lower plate and expanding mechanism can radially horizontal slide, expansion
Mechanism is equipped with the conical surface coordinated with cone taper, and spring ring is installed on expanding mechanism periphery.
Further, the expanding mechanism is disposed radially including multiple expansion blocks and multiple feather keys, multiple feather keys
And circumference uniform distribution, on lower plate, each feather key is fixedly connected by positioning pin and screw with lower plate, multiple expansion blocks
Corresponded with multiple feather keys and each expansion block is radially slidably connected with corresponding feather key.
Further, the expansion block number is 10.
Further, it is provided with oil guide groove between the expanding mechanism and cone.
Further, the expanding mechanism is having spring ring recess at upper and lower ends, is installed in spring ring recess
Spring ring.
The utility model has the advantages that：It is uniformly multiple in circumference to be positioned radially expansion block, by the cone for expanding block and cone
Degree, which coordinates, realizes radially sliding for expansion block, completes the expansion of steel wheel rim body, can ensure the molding surface size requirement of wheel rim body very well,
It is easy to operate and apparatus structure is simple.
Brief description of the drawings
Fig. 1 is a kind of overall construction drawing of steel tire rim extension die described in the utility model；
Fig. 2 is the overlooking the structure diagram that block is expanded in Fig. 1；
Fig. 3 is the structure diagram of lower plate in Fig. 1；
In figure：1- upper plates, 2- cones, 3- expansion blocks, 4- feather keys, 5- spring rings, 6- positioning pins, 7- lower plates.
Embodiment
The technical solution of the utility model is discussed in detail below in conjunction with attached drawing：
As shown in Figure 1, a kind of steel tire rim extension die, by upper plate 1, lower plate 7, cone 2, expansion block 3, feather key
4 and spring ring 5 form.
As shown in Figure 1 to Figure 3, cone 2 is fixedly connected on 1 bottom surface of upper plate by screw；10 feather keys 4 are radially set
Put and circumference uniform distribution is on lower plate 7, each feather key is fixed by two positioning pins 6 and two screws with lower plate 7 to be connected
Connect, 10 expansion blocks 3 corresponded with 10 feather keys 4 and each expand block 3 with the corresponding feather key 4 radially company of slip
Connect, expansion block 3 is equipped with the conical surface with 2 taper fit of cone, and expands and oil guide groove is provided between block 3 and cone 2 in favor of lubrication；
Expansion block 3 can be slided along feather key 4；Expansion block 3 is having spring ring recess at upper and lower ends, and spring ring is installed on bullet
In spring coil groove.
The operation principle of the utility model is introduced briefly below：
First steel wheel rim to be expanded is sleeved on mould, then uses and pneumatically pressure is applied on upper plate 1, upper plate
1 connection cone 2, moves down cone 2, and expansion block 3 is reached along 4 radial dilatation of feather key, 5 radial dilatation of spring ring, wheel rim body
To after molding surface size requirement, pressure is cancelled, and expansion block 3 shrinks back original position under the action of spring ring 5.
