Abstract
The utility model discloses a kind of anti-scrap bouncing mechanisms of die punching, including Kong Chong and air inlet pipe, the venthole of both ends of the surface is rushed in the Kong Chong with axially extending and through hole along its, the upper section of the venthole is linkage section, the both ends of the air inlet pipe all have gas-tpe fitting, wherein one end of air inlet pipe is connected to linkage section by gas-tpe fitting, and is connected with venthole.The utility model effectively avoids the case where jump bits damage product.
Description
Technical field
The utility model relates to a kind of anti-scrap bouncing mechanisms of die punching.
Background technique
In the prior art, it since die punching station waste material is too small and comparison rule, while being glued on material in punching course
There is lubricating oil, therefore waste material is attached on formed punch to be taken up to cause to jump and considers to be worth doing in formed punch shearing, causes the deformation or great of product
It weighs wounded, therefore there is improved spaces.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a mold the anti-scrap bouncing mechanism of punching, effectively keeps away
Exempt to jump the case where bits damage product.
To achieve the above object, the utility model provides following technical solution:
A kind of anti-scrap bouncing mechanism of die punching, including Kong Chong and air inlet pipe, the Kong Chong are interior with axially extending along its
And through hole rushes the venthole of both ends of the surface, the upper section of the venthole is linkage section, and the both ends of the air inlet pipe all have tracheae
Connector, wherein one end of air inlet pipe is connected to linkage section by gas-tpe fitting, and is connected with venthole.
Preferably, the gas-tpe fitting is threadedly engaged with linkage section connect.
Preferably, the lower section of the venthole is construction section, is provided with spring, the upper end of the spring in the construction section
It is fixed in construction section, the lower end of spring is located at the outside of venthole in its natural state.
Preferably, the diameter of the construction section is greater than the diameter of venthole.
Preferably, the lower end of the spring is connected with annulus.
The advantages of the utility model are as follows: after Kong Chong shear offs scrap from material, connect gas source using air inlet pipe, just
The scrap for being adsorbed on hole and sweeping away end can be blown away, it is therefore prevented that the case where jumping bits, to prevent the impaired situation of product.
Detailed description of the invention
Fig. 1 is the schematic diagram of the anti-scrap bouncing mechanism of die punching provided by the present embodiment.
Specific embodiment
It is further described in conjunction with anti-scrap bouncing mechanism of the Fig. 1 to the utility model die punching.
A kind of anti-scrap bouncing mechanism of die punching, including hole punching 1 and air inlet pipe 5, the hole rushes to have in 1 prolongs along its axial direction
The venthole 2 that simultaneously through hole rushes 1 both ends of the surface is stretched, the upper section of the venthole 2 is linkage section 21, and the both ends of the air inlet pipe 5 are equal
With gas-tpe fitting 51, wherein one end of air inlet pipe is connected to linkage section 21 by gas-tpe fitting 51, and leads with venthole 2
Logical, the other end of air inlet pipe 5 connects gas source by gas-tpe fitting 51, to realize that gas source is blown to venthole 2, will be adsorbed on
The scrap that hole rushes on 1 lower end surface is blown away, and effectively avoids jumping the case where bits are by damage of product.
The present embodiment is further arranged to: the gas-tpe fitting 51 is threadedly engaged with linkage section 21 to be connect.That is linkage section 21
Inner wall on there is internal screw thread, there is external screw thread, to realize that air inlet pipe and hole are rushed 1 and be stably connected on gas-tpe fitting 51.
The present embodiment is further arranged to: the lower section of the venthole 2 is construction section 22, is provided in the construction section 22
The upper end of spring 3, the spring 3 is welded in construction section 22, and the lower end of spring 3 is located at the outer of venthole 2 in its natural state
Portion, after scrap is sheared from material, the lower end of the spring 3 can generate extruding to the scrap that hole rushes on 1 lower end surface is adsorbed on
Power, the gas which generates can effectively and quickly remove the scrap of absorption, avoid jumping and consider to be worth doing.
The present embodiment is further arranged to: the diameter of the construction section 22 is greater than the diameter of venthole, which avoids
Spring 3, which circulates in venthole 2 to air-flow, generates the case where hindering.
The present embodiment is further arranged to: the lower end of the spring 3 is connected with annulus 4, which can play pad shield and make
With.
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.
