Specific embodiment
In conjunction with attached drawing, a kind of hole punched device, including be inserted in the intraluminal pipe die 10 of punching pipe A, the tube wall of pipe die 10
On open up through hole setting formed punch 20, formed punch 20 in the through-hole make protruding out and bouncing back perpendicular to 10 tube core direction of pipe die
Mobile, the end 21 of the formed punch 20 outside pipe die 10 is long axis with the consistent elliptic cylindrical shape in 10 tube core direction of pipe die and end face is
The center-of-curvature line in concave arc shape stamp face 23, concave arc shape stamp face 23 is vertical with the tube core of pipe die 10.The utility model is by formed punch
The end face of 20 end 21 is set as concave arc shape stamp face 23, and the profile of the end 21 of formed punch 20 can be made to form blade in this way,
For treating the shearing punching of punching pipe A tube wall；21 shaft of end of formed punch 20 be elliptic cylindrical shape, elliptical long axis with
The tube core direction of pipe die 10 is consistent, under the mating reaction in 21 elliptic cylindrical shape shaft of end and concave arc shape stamp face 23, treats punching
It to the notch on punching pipe A tube wall is ellipticity after the pipe A punching of hole, and elliptical long axis and tube core direction one to punching pipe A
It causing, this allows for the size being less than on axial direction to the size of the notch on punching pipe A tube wall in a circumferential direction, thus
Guarantee that the aperture edge height of the flanging bore after flange is almost the same, improve the flatness in the flanging bore aperture to punching pipe A,
It ensure that brazing quality.
Further, the concave arc shape stamp face 23 on the projection surface be projected as whole oval profile and the wheel
Wide section is the symmetrical profiles section of short axle side, center-of-curvature line of the perspective plane perpendicular to concave arc shape stamp face 23.Specifically,
The concave arc degree in concave arc shape stamp face 23 is determined according to the caliber to punching pipe A, to guarantee that formed punch 20 is managed perpendicular to pipe die 10
When core direction protrudes out mobile, the machined surface profile line in concave arc shape stamp face 23 can contact simultaneously with the inner tubal wall to punching pipe A,
So that punching pipe A tube wall can be treated in punching while implementing shear action, it is ensured that stress is concentrated, and avoids treating punching
Pipe A tube wall causes to damage, and influences flange effect.
Further, the formed punch 20 further includes cylindrical ontology 22, and the body diameter of ontology 22 is greater than formed punch 20
The elliptical long axis of end 21 passes through chamfered transition between the end 21 and ontology 22 of formed punch 20.When it is implemented, formed punch 20
End 21 is punched out for treating punching pipe A, and the ontology 22 of formed punch 20 carries out flange for treating punching pipe A, between the two
By chamfered transition, after completing to treat the punching of punching pipe A, the tube wall that chamfered part can treat punching pipe A carries out rollover
Side, then flange is carried out by the tube wall that ontology 22 treats punching pipe A, so that the tube wall to punching pipe A be protected not to be damaged in flange
Wound improves flange quality.
Further, setting power rail 30 is connected with formed punch 20 and formed punch 20 is driven to protrude out and return in the lumen of pipe die 10
Contracting movement.Power rail 30 is arranged in the lumen of pipe die 10, so that overall structure is more compact, both can guarantee the dynamic of formed punch 20
Power supply, and can be avoided power rail 30 and to the interference between punching pipe A.
Further, the brace on skewed slot or inclined hole and power rail 30 is set on 20 ontology 22 of formed punch in pipe die 10
Section 31 cooperates, and driving formed punch 20 protrudes out when power rail 30 moves in pipe die 10 along tube core direction and retraction moves.By oblique
The cooperation of slot or inclined hole and brace section 31, so that the displacement of power rail 30 in the axial direction is converted to position in the radial direction
It moves, to ensure the movement that protrudes out and bounce back of formed punch 20.
Further, the through hole of same core arrangement is opened up on pipe die 10, the both ends of formed punch 20 are placed in the hole, and formed punch 20
The skewed slot 24 that section is T-type is set on body 22, and the brace section 31 on power rail 30 is inserted in 24 vallecular cavity of skewed slot and between the two
Composition is slidably matched.It is opened up by through hole on pipe die 10, it is ensured that formed punch 20 avoids formed punch 20 convex in intraluminal position
Run-off the straight when stretching and bouncing back mobile and influence flange precision.Preferably, the inner wall of skewed slot 24 is with 31 outer peripheral surface of brace section
Shiny surface, to reduce the sliding friction between 24 brace section 31 of skewed slot, to reduce loss of the power in transmittance process.
Preferably, the T-shaped plate that the brace section 31 on power rail 30 is generally coincide with 24 cross section profile of skewed slot, T-shaped plate
Wing plate 311, web 312 are inserted in the chamber of the vallecular cavity section 241 of skewed slot 24, closing in section 242 respectively and constitute limit between the two
Position guiding cooperation.Brace section 31 on power rail 30 is also provided with it is at T-shaped, after such brace section 31 cooperates with skewed slot 24, wing plate
311 plant the vallecular cavity section 241 for arriving skewed slot 24, so that limiting skewed slot 24 can only move radially along the length direction of wing plate 311, thus
Ensure the accuracy of power transmitting.
As one of embodiment of the utility model, as the 25mm to punching pipe A, when pipe wall thickness is 1.2mm, on
The elliptical long axis in end 21 for stating formed punch 20 is 12mm, and the diameter of short axle 8mm, the ontology 22 of formed punch 20 are 16.2mm, complete
After piercing and flanging process, as shown in Fig. 2, the opening's edge of the flanging bore to punching pipe A is flat mouth shape, precision when with cooperation is in charge of
It is higher, effectively raise brazing quality.
