Description

Technical Field

[0001] The utility model relates to the technical field of hexagon across flats punches, in particular to a hexagon across flats punch with high precision. Background Art

[0002] A hexagon across flats punch is a metal part in mechanical tools, especially used for stamping dies. It directly contacts the material during the stamping process, causing the material to deform or be cut, so as to obtain the required finished or semi-finished products.

[0003] The hexagon across flats punch is installed in the tailstock sleeve of a lathe and punches the workpiece. Although the hexagon across flats punch can be installed in the tailstock sleeve through a punch fixture. However, if only relying on the punch fixture to fix the hexagon across flats punch, the fixing effect is not particularly good. The hexagon across flats punch will have a slight deviation due to the impact and vibration generated during the processing, thus reducing its stability, and this will reduce the processing precision of the hexagon across flats punch. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a hexagon across flats punch with high precision is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A punch fixture is arranged in the tailstock sleeve, and a detachable hexagon across flats punch is installed on the punch fixture. And a threaded ring is fixedly arranged on the outer side of the punch fixture; A reinforcing ring is fixedly sleeved on the shank of the hexagon across flats punch. A plurality of reinforcing cavities are arranged on the surface of the reinforcing ring facing the threaded ring. And reinforcing members are arranged on the threaded ring corresponding to the reinforcing cavities in a matching manner.

[0007] In addition, the preferred structure is that set screws are assembled on the outer sides of the punch fixtures, and set screw holes are correspondingly and adaptively arranged on both the punch fixtures and the hexagon across flats punches.

[0008] In addition, the preferred structure is that the outer side of the threaded ring is provided with external threads, and a detachable sleeve is sleeved on the threaded ring.

[0009] In addition, the preferred structure is that internal screw grooves are arranged on the inner wall of the sleeve, and the internal screw grooves are all adapted to the external threads.

[0010] In addition, the preferred structure is that a retaining ring is fixedly arranged on one side of the sleeve, and the diameter of the inner diameter of the retaining ring is smaller than the diameter of the outer diameter of the reinforcing ring.

[0011] In addition, a preferred structure is that a plurality of reinforcing members are fixedly arranged in an "annular" array on the outer side of the threaded ring, and the reinforcing cavities on the reinforcing ring are all adapted to the reinforcing members.

[0012] The beneficial effects of the present utility model are as follows: The hexagonal across flats punch is assembled on the punch fixture through the setscrew. Through the matching and clamping between the reinforcing member and the reinforcing cavity, and the clamping of the reinforcing ring by the retaining ring on the sleeve, the stability of the hexagonal across flats punch after installation can be improved, so as to improve the fixing effect of the hexagonal across flats punch on the punch fixture, thereby reducing the offset degree of the hexagonal across flats punch during punching due to impact and vibration, and improving its punching accuracy.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Refer to Figures 1-5, A high-precision hexagon across flats punch, including a tailstock sleeve 1 and a hexagon across flats punch 2. A punch clamp 11 is arranged inside the tailstock sleeve 1, and a detachable hexagon across flats punch 2 is installed on the punch clamp 11. And a threaded ring 4 is fixedly arranged on the outer side of the punch clamp 11. A reinforcing ring 21 is fixedly sleeved on the shank of the hexagon across flats punch 2. A plurality of reinforcing cavities 22 are formed on one side of the reinforcing ring 21 facing the threaded ring 4. And a reinforcing member 42 is adaptively arranged on the threaded ring 4 corresponding to the reinforcing cavities 22.

[0021] Among them, set screws 12 are assembled on the outer sides of the punch clamp 11. And set screw holes are adaptively formed on both the punch clamp 11 and the hexagon across flats punch 2 corresponding to the set screws 12. The tailstock sleeve 1 is provided with the punch clamp 11. The user can insert the shank of the hexagon across flats punch 2 into the punch clamp 11. Subsequently, insert the set screw 12 through the set screw hole in the punch clamp 11 and into the set screw hole in the hexagon across flats punch 2. In this way, the fixed connection between the hexagon across flats punch 2 and the punch clamp 11 can be realized through the set screw 12. It should be noted that the specific structures and working methods of the tailstock sleeve 1, the punch clamp 11, the set screw 12 and the set screw holes are all prior arts, so no more details will be given.

[0022] Among them, an external thread 41 is arranged on the outer side of the threaded ring 4. And a detachable sleeve 3 is sleeved on the threaded ring 4. Internal screw grooves 31 are formed on the inner wall of the sleeve 3. And the internal screw grooves 31 are all adapted to the external thread 41. Through the adapted connection between the internal screw grooves 31 and the external thread 41, the sleeve 3 can be fixedly installed on the outer side of the threaded ring 4.

[0023] Among them, a retaining ring 32 is fixedly arranged on one side of the sleeve 3. And the diameter of the inner diameter of the retaining ring 32 is smaller than the diameter of the outer diameter of the reinforcing ring 21. Through the arrangement of the retaining ring 32, the fixed clamping of the reinforcing ring 21 can be realized.

[0024] Among them, a plurality of reinforcing members 42 are fixedly arranged on the outer side of the threaded ring 4 in an "annular" array. And the reinforcing cavities 22 on the reinforcing ring 21 are all adapted to the reinforcing members 42.
