Description

Pressure reaming tool

Technical Field

The utility model relates to a fixture, in particular to a pressure reaming fixture.

Background

The fixture is a technological device for fast fastening workpiece during machining to maintain correct relative positions of machine tool, cutter and workpiece, and is an indispensable part for machining. As shown in fig. 1, in a workpiece 100, a middle hole 101 is formed in the middle of the workpiece 100, and the middle hole 101 needs to be reamed, in the conventional reaming, a punch is driven by a press machine to ream the middle hole 101 of the workpiece 100, and after reaming, the punch is clamped in the middle hole 101, so that stripping of the workpiece 100 is very difficult.

Disclosure of utility model

The utility model aims to provide a pressure reaming tool capable of automatically finishing workpiece stripping.

In order to achieve the above object, the technical solution of the present utility model is:

The utility model relates to a pressure reaming tool which comprises a die frame, an upper die plate, a punch and a stripping block;

The upper die plate is fixed on the die carrier top plate, the upper end of the punch is fixed on the upper die plate, the lower end of the punch is opposite to the stripping block, a through hole is formed in the center of the upper portion of the stripping block, the punch can pass through the through hole, a groove for placing a workpiece is formed in the lower portion of the stripping block, the groove is located right below the through hole, and the stripping block is fixed on the die carrier bottom plate.

The lower portion of the punch is tapered to expand the middle hole of the workpiece.

The two sides of the stripping block are provided with locking plates extending outwards.

After the scheme is adopted, the die carrier comprises the die carrier, the upper die plate, the punch and the stripping block, the groove at the lower part of the stripping block forms a processing position of a workpiece, the punch penetrates through the through hole in the stripping block and then is inserted into the middle hole of the workpiece to conduct reaming, the punch ascends after reaming, the workpiece clamped on the punch is blocked by the top surface of the groove of the stripping block and is stripped from the punch, and stripping of the workpiece is automatically completed.

The utility model will be further described with reference to the drawings and the specific examples.

FIG. 2 is an isometric view of the present utility model mounted on a press;

fig. 3 is an isometric view of the stripping block of the present utility model.

Detailed Description

As shown in fig. 1-3, the utility model relates to a pressure reaming tool, which comprises a die carrier 1, an upper die plate 2, a punch 3 and a stripping block 4.

The upper die plate 2 is fixed on a top plate 11 of the die frame 1, the upper end of the punch 3 is fixed on the upper die plate 2, and the lower end of the punch 3 is opposite to the stripping block 4.

The two sides of the stripping block 4 are provided with locking plates 41 extending outwards, the center of the upper part of the stripping block 4 is provided with a through hole 42, the through hole 42 can be penetrated by the punch 3, the lower part of the stripping block 4 is provided with a groove 43 for placing the workpiece 100, the groove 43 is positioned right below the through hole 42, and the stripping block 4 is fixed on the bottom plate 12 of the die carrier 1.

The lower portion of the punch 3 is tapered to expand the middle hole 101 of the work 100.

The working principle of the utility model is as follows:

The groove 43 at the lower part of the stripping block 4 forms a processing station of the workpiece 100, the workpiece 100 is placed in the groove 43 at the lower part of the stripping block 4, the press machine 200 drives the punch 3 to pass through the through hole 42 on the stripping block 4 and then insert the middle hole 101 of the workpiece 100 for reaming, the punch 3 ascends after reaming, the workpiece 100 clamped on the punch 3 is blocked by the top surface of the groove 43 of the stripping block 4 and is stripped from the punch 3, and the stripping of the workpiece is automatically completed.

The foregoing description is only illustrative of the preferred embodiments of the present utility model, and is not intended to limit the scope of the utility model, i.e., the equivalent changes and modifications to the utility model as described in the claims and specification should be considered as falling within the scope of the utility model.
