Abstract
The utility model discloses a kind of enhanced buoyant pin, "-" type guide groove is offered on the side wall of the buoyant pin, the depth of the "-" type guide groove is less than or equal to 1/5th of buoyant pin diameter length；It is provided on the side wall of the buoyant pin and limits the positioning region that buoyant pin circumferentially rotates, the positioning region is certain bit plane, and the positioning plane is located at the other side that buoyant pin corresponds to "-" type guide groove.The utility model effectively improves the structural strength and guide precision of buoyant pin.
Description
Technical field
The utility model relates to a kind of enhanced buoyant pins.
Background technique
In the prior art, the structure of buoyant pin forms guide as shown in figure 3, opening up an annular groove on the side wall of buoyant pin
Slot, there are two disadvantages for tool under the structure: 1, the contact of the side with position 4 of punching press steel 2 is point contact, leads to the precision being oriented to
It is poor；2, opening up due to annular groove causes the contact surface between position 1 and position 2 to reduce, so that position 1 and position 2 are connected
It is in easy fracture after stress.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of enhanced buoyant pin, effectively improves buoyant pin
Structural strength and guide precision.
To achieve the above object, the utility model provides following technical solution:
A kind of enhanced buoyant pin offers "-" type guide groove, the "-" type guiding on the side wall of the buoyant pin
The depth of slot is less than or equal to 1/5th of buoyant pin diameter length；It is provided on the side wall of the buoyant pin and limits buoyant pin week
To the positioning region of rotation.
Preferably, the positioning region is certain bit plane.
Preferably, the positioning plane is located at the other side that buoyant pin corresponds to "-" type guide groove.
The advantages of the utility model are as follows: be obviously improved the structural strength of buoyant pin, and improved to stamping steel plate
Guiding accuracy.
Detailed description of the invention
Fig. 1 is the front view of enhanced buoyant pin provided by the present embodiment；
Fig. 2 is the axial sectional view of enhanced buoyant pin provided by the present embodiment；
Fig. 3 is the schematic diagram of buoyant pin in the prior art.
Specific embodiment
The enhanced buoyant pin of the utility model is further described in conjunction with Fig. 1 to Fig. 2.
A kind of enhanced buoyant pin offers "-" type guide groove 11 on the side wall of the buoyant pin 1, and the "-" type is led
It is less than or equal to 1/5th of 1 diameter length of buoyant pin to the depth of slot 11；It is floating that restriction is provided on the side wall of the buoyant pin 1
The positioning region 12 that material pin 1 circumferentially rotates.In the present embodiment, the slot bottom of "-" type guide groove is plane, thus with stamping steel plate 2
It is contacted between side wall for line, increases contact area, improve the precision of guiding；On the other hand, 11 phase of "-" type guide groove
To annular guide groove is opened up, buoyant pin 1 can be significantly improved on shaping area at the position of guide groove two sections, because
The case where this effectively enhances the structural strength between guide groove two sections, avoids fracture；Positioning region 12 exists for buoyant pin 1
Positioning on grade mould guarantees the stability of its guide.
The present embodiment is further arranged to: the positioning region 12 is certain bit plane, and the structure is simple, and is easy to fixed.Make
Buoyant pin 1 is set in the same hole with planar portions, so that the plane of plane and buoyant pin 1 in hole is mutually pasted by the used time
It closes, can effectively avoid buoyant pin 1, there is a situation where circumferentially rotate in hole.
The present embodiment is further arranged to: the positioning plane is located at the another of the corresponding "-" type guide groove 11 of buoyant pin 1
Side, the setting is easy to process, and positioning plane with "-" type guide groove 11 being uniformly distributed on buoyant pin 1, can enhance float
Expect the whole structural strength of pin 1.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
Claims (3)
