Description
Technical Field
The utility model relates to a pipe fitting pressure testing field, concretely relates to automobile-used petrol is cut-out press for fuel distribution system pipe.
Background
The existing gasoline engines adopt conventional circular tubes to improve the response speed of fuel and improve the mixing precision of fuel, thereby achieving higher combustion performance, improving the performance of the engine and saving energy.
When the distribution pipe is responsible for surface machining round hole, directly punch a hole on the pipe surface for the convenience of processing usually, this kind of mode is convenient for the processing in hole, but the round hole is on the face of cylinder after punching a hole, leads to the later stage to assemble difficulty and inefficiency.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defect of prior art, the utility model aims to provide a cut-out press is used to automobile-used petrol fuel distribution system pipe.
A kind of vehicle gasoline fuel oil distribution system circular tube uses the cut-out press, including:
a punch head device,
the lower part of the punch device is provided with a punch,
the lower part of the punch device is provided with a corresponding female die device, the middle part of the female die device is provided with a female die, the front section of the female die is provided with an embedded structure, and the upper part of the embedded structure is provided with a blanking hole so as to reduce the stress of the female die;
the front punching clearance of the female die is 0.45-0.55mm and is less than 0.5T of the thickness of the plate.
In a preferred embodiment of the present invention, the front punching gap of the female die is 0.5mm, which is smaller than 0.5T of the thickness of the plate.
In a preferred embodiment of the present invention, the length of the mosaic structure is 30-40 mm.
The beneficial effects of the utility model reside in that:
the utility model discloses a cut-out press for vehicle gasoline fuel distribution system pipe has solved unilateral clearance undersize, the low problem of die intensity to solve machining center machining efficiency's problem, stability, uniformity and the reliability of the little clearance cut-out press die of cambered surface that the invention can guarantee the elliptical tube, make product performance reach international advanced level.
Drawings

Fig. 2 is a schematic structural diagram 2 of the present invention.
Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
As shown in fig. 1 or 2, the punching die 100 for the circular tube of the gasoline fuel distribution system for a vehicle includes a punch means 110, and a punch 111 for punching the circular tube of the gasoline fuel distribution system for a vehicle is mounted on a lower portion of the punch means 110.
The lower part of the punch device 110 is provided with a corresponding female die device 120, the middle part of the female die device 120 is provided with a female die 121, the front section of the female die 121 is provided with an embedded structure 130, and the upper part of the embedded structure 130 is provided with a blanking hole 131 so as to reduce the stress of the female die; the punching gap of the front surface of the concave die 121 is 0.5mm and is less than 0.5T of the plate thickness.
Because of possessing the above structure, the utility model discloses a theory of operation lies in:
the front surface of a circular tube (not shown in the figure) of the gasoline and fuel oil distribution system for the vehicle is inserted into the female die 121 and pushed to the positioning surface at the bottom of the female die 121, the punch 111 is pressed down to punch the circular tube (not shown in the figure) of the gasoline and fuel oil distribution system for the vehicle, and waste reaches the blanking hole 131 of the embedded structure 130 arranged at the front section of the female die 121. At the moment, the waste is blown out from the side edge and does not need to fall freely by gravity, and the strength of the die 121 can be ensured to the maximum extent because the blanking hole of the die 121 is not cut through. In the process, the design scheme ensures that the punched hole can be reliably produced.
