Description

Assembling die

Technical Field

The utility model relates to the field of dies, in particular to an assembly die.

Background

The clutch shaft of the silicone oil fan is a spare part in an automobile air conditioner and engine cooling system, is assembled by forging the shaft, quenching and tempering, numerical control machining and knurling, and is in small interference fit with a wafer, the runout of the end face of the wafer on the large end face of the shaft is required to be less than or equal to 0.1 after the assembly, and the requirement on the assembly precision cannot be met by using a common assembly pressure head due to the flatness of the wafer and the precision influence of a press.

Therefore, it is necessary to provide a new technical solution.

Disclosure of utility model

In order to solve the technical problems in the prior art, the utility model discloses an assembly die, and the specific technical scheme is as follows:

the utility model provides an assembly die, which comprises an upper punch, a lower die holder and an assembly press head,

The lower die holder is provided with a die cavity, a workpiece is placed in the die cavity of the lower die holder,

The assembly pressure head is arranged on the top end face of the workpiece, the bottom of the assembly pressure head is arranged as a plane, the top of the assembly pressure head is provided with an arc-shaped protruding structure,

The upper punch is arranged above the assembly press head, and the upper punch is used for stamping and forming the workpiece by pushing the assembly press head downwards.

Further, the protruding structure of the assembly press head is hemispherical.

The utility model has the following beneficial effects:

1. The parallelism of the end surfaces of the two assembly parts after the assembly press head is used is generally about 0.05mm, and the requirement that the parallelism of customers is less than or equal to 0.1mm can be met.
