After the bolt screw in bolt hole was screwed, then rotatory screw thread push rod will make screw thread push rod push up first slider and move forward, and first slider is when removing, under the effect on first direction inclined plane and second direction inclined plane, promotes the tank bottom surface butt in second slider and the groove of only revolving, because the groove depth in only revolving groove diminishes along the direction of unscrewing of bolt, has just so restrained the bolt and has rotated toward the direction of unscrewing to the effect that the bolt has loosened has been played.
Preferably, the first guide slope is parallel to the second guide slope.
Preferably, the rotation preventing grooves are provided in four numbers and are uniformly arranged in the circumferential direction of the bolt hole.
Preferably, the groove bottom surface is a circular arc surface.
Preferably, the punch body is made of tungsten steel. The tungsten steel has high hardness, and can prevent the punch from deforming and damaging in the stamping process.
Preferably, the block is made of tungsten steel. The tungsten steel has high hardness, and can prevent the character block from deforming and damaging in the stamping process.
The invention has the beneficial effects that: when the invention is actually used, the character block can be replaced according to actual needs, so that when the character mark on the part needs to be changed, only the character block needs to be replaced, the punch does not need to be replaced, and the use is more convenient.

In the figure: 1. the punch comprises a punch body, a punch 2, a threaded connection hole, a punch 3, a character block, a bolt hole 4, a bolt 5, a bolt, a punch groove 6, a character block groove 7, a character projection 8, a counter bore 9, a first slide hole 10, a first slide block 11, a second slide block 12, a rotation stopping groove 13, a threaded hole 14, a threaded push rod 15 and a groove bottom surface.
Detailed Description
The invention is further described by the following detailed description in conjunction with the accompanying drawings.
Example 1:
as shown in fig. 1 to 5, a finishing punch includes a punch body 1. The punch body 1 is made of tungsten steel. One end of the punch body 1 is provided with a block groove 6. The bottom of the block groove 6 is provided with a bolt hole 4. The block groove 6 is embedded with a block 3. The block 3 is made of tungsten steel. The block 3 is provided with a font projection 7. The block 3 is fixed in the block groove 6 by the bolt 5. The block 3 is provided with a counter bore 8 for mounting the bolt 5. The bolt 5 is connected to the bolt hole 4 through the counter bored hole 8. The other end of the punch body 1 is provided with a threaded connecting hole 2.
The bolt is provided with a first slide hole 9 and a threaded hole 13. The first slide hole 9 and the threaded hole 13 are both provided along the axial direction of the bolt 5. The first slider 9 communicates with the threaded hole 13. The first slider 9 and the threaded hole 13 penetrate through both ends of the bolt, respectively. The cross section of the first slide hole 9 is rectangular. A first slider 10 is slidably disposed in the first slide hole 9. The side surface of the first slide hole 9 is provided with a second slide hole perpendicular to the first slide hole 9. The second slide block 11 is arranged in the second slide hole in a sliding mode. The first slider 10 is provided with a first guide inclined plane, and the second slider 11 is provided with a second guide inclined plane matched with the first guide inclined plane. The first guide slope and the second guide slope are parallel. The first guide slope is in contact with the second guide slope. The bolt hole 4 is provided with a rotation stop groove 12 in the circumferential direction. The rotation stopping grooves 12 are provided with four rotation stopping grooves and are uniformly arranged in the circumferential direction of the bolt holes 4. The groove bottom surface 15 of the rotation stopping groove 12 is a circular arc surface. The groove depth of the rotation stop groove 12 decreases in the direction of the unscrewing of the bolt 5. One end of the second slider 11, which is away from the first slider 10, abuts against the groove bottom surface 15 of the rotation stop groove 12. A threaded push rod 14 is connected in the threaded hole 13. One end of the threaded push rod 14 abuts against the first slider 10. After the bolt screw in bolt hole was screwed, then rotatory screw thread push rod will make screw thread push rod push up first slider and move forward, and first slider is when removing, under the effect on first direction inclined plane and second direction inclined plane, promotes the tank bottom surface butt in second slider and the groove of only revolving, because the groove depth in only revolving groove diminishes along the direction of unscrewing of bolt, has just so restrained the bolt and has rotated toward the direction of unscrewing to the effect that the bolt has loosened has been played.
When the invention is used, a finishing punch is required to be installed on the punching equipment. The character block is fixedly connected in the character groove through a bolt, and the character block can be conveniently detached and installed. When the utility model is used, the block can be changed according to actual need, so when the character mark on the part needs to be changed, only need to change the block can, need not to change the drift, it is comparatively convenient to use. The threaded connecting hole arranged at one end of the punch body is convenient for installing and fixing the punch on the punching equipment.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
