Description
Technical field
The utility model belongs to wiper counter-boring techniques field, and in particular to a kind of applied to automobile wiper connecting rod head
Hole expansion die.
Background technique
Connecting rod is one of main parts size of automobile wiper, and the vehicle of automobile is different, and connecting rod is also different, and common adopts
" tubular type " connecting rod made of steel pipe, traditional connecting rod make complexity, and need manually to go to dig out the reaming of connecting rod, and make essence
Low, and high labor cost is spent, and the manufacture of this hole expansion die is easy, is easy to dismount, and because equipped with ejector beam, can use pressure makes
The smooth depanning of workpiece, and manual compression is not needed, cost of labor is saved, while increasing the precision of manufacture.
Utility model content
The purpose of this utility model is to provide a kind of hole expansion dies applied to automobile wiper connecting rod head, on solving
State the problem of proposing in background technique.
To achieve the above object, the utility model provides the following technical solutions: one kind being applied to automobile wiper connecting rod head
Hole expansion die, including taper matrix, the first spring, taper clamping sleeve, supporting plate, mandril, taper punch-pin, second spring, workpiece,
Buffer, the taper matrix left and right sides are connect with the first spring, and cone is equipped with below the middle position of the taper matrix bottom
Shape punch-pin, part is fixed by taper clamping sleeve on the taper punch-pin, is connected at left and right sides of the taper clamping sleeve with second spring
It connects, the taper clamping sleeve is located on supporting plate, and the supporting plate is supported by mandril, taper male bottom position and buffer
Connection.
Further, workpiece is placed between the taper matrix and taper punch-pin.
Further, the recess of the taper matrix is in rounded shape.
The technical effect and advantage of the utility model: the manufacture of this hole expansion die is easy, is easy to dismount, and because being equipped with liftout
Bar, can use pressure makes the smooth depanning of workpiece, and does not need manual compression, saves cost of labor, while increasing manufacture
Precision.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the hole expansion die applied to automobile wiper connecting rod head of the utility model；
In figure: taper matrix 1, the first spring 2, taper clamping sleeve 3, supporting plate 4, mandril 5, taper punch-pin 6, second spring 7,
Workpiece 8, buffer 9.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment, based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1:
The utility model provides a kind of hole expansion die applied to automobile wiper connecting rod head as shown in Figure 1, including
Taper matrix 1, the first spring 2, taper clamping sleeve 3, supporting plate 4, mandril 5, taper punch-pin 6, second spring 7, workpiece 8, buffer
9, the recess of the taper matrix 1 is in rounded shape, and 1 left and right sides of taper matrix is connect with the first spring 2, and the taper is recessed
It is equipped with taper punch-pin 6 below 1 bottom middle position of mould, workpiece 8, the cone are placed between the taper matrix 1 and taper punch-pin 6
Part is fixed by taper clamping sleeve 3 on shape punch-pin 6, and 3 left and right sides of taper clamping sleeve is connect with second spring 7, the cone
Shape clamping sleeve 3 is located on supporting plate 4, and the supporting plate 4 is supported by mandril 5, and 6 bottom position of taper punch-pin and buffer 9 connect
It connects.
When work, workpiece first covers on taper punch-pin, when taper matrix downlink, by workpiece pressure together with taper clamping sleeve
Tightly, when continuing traveling downwardly, taper matrix and taper clamping sleeve in the case where the tapered surface on taper punch-pin pushes, both make to drive workpiece to
Both sides are opened, and when taper matrix uplink, under the elastic force effect of buffer, to push supporting plate to move upwards, workpiece is also therewith
It moves upwards, that is, can be taken off bulletin and see, at the same time, taper matrix and taper clamping sleeve are under the action of the spring, automatic to be closed
The technical effect and advantage of the utility model: the manufacture of this hole expansion die is easy, is easy to dismount, and because being equipped with liftout
Bar, can use pressure makes the smooth depanning of workpiece, and does not need manual compression, saves cost of labor, while increasing manufacture
Precision.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
