In order to further improve ram efficiency, reduce punching press dynamics, in one embodiment, as shown in Fig. 2 the notch
203 width is gradually reduced from one end close to second end 202 to one end close to the first end 201, for example, described
The width of notch 203 reduces with the increase of the depth of the notch 203, for example, the quilt of the second end 202 of the tube wall 210
The notch 203 is divided into some portions 230 of blooming, it should be understood that in each embodiment, the width of notch 203 and blooms
The width in portion 230 be along the length on the circumferencial direction of tube wall 210, so, due to notch 203 opening portion width compared with
Greatly, so, width of the tube wall 210 in the portion 230 of blooming at the second end 202 is smaller, and intensity is relatively low, easy deformation bending, is conducive to
Reduce punching press dynamics, further improve ram efficiency, with the increase of the depth of notch 203, the width of notch 203 reduces, and opens
The width in flower portion 230 accordingly increases, the intensity increase of tube wall 210 so that the intensity of tube wall 210 for being pressed on product surface is bigger,
And then enabling the portion of blooming 230 to be closely pressed together on product surface so that the intensity of riveting is bigger so that riveting is more firm.
More easily washed open in order that obtaining tube wall 210 so that punching press dynamics is smaller, for example, the notch has trapezoidal section
Face, for example, section of the notch on the circumferential surface of the tube wall is trapezoidal, for example, as shown in Fig. 2 the notch 203
With triangular-section, for example, section of the notch 203 on the circumferential surface of the tube wall 210 is triangle, for example,
The opening angle θ of the notch 203 is 10 °~20 °, for example, the outside of the notch 203 sets cell wall, pair of the notch 203
The angle for two cell walls answered is the opening angle θ of the notch 203, for example, the opening angle θ of the notch 203
For 16 °, it should be understood that the opening angle of notch 203 is bigger, then the width in corresponding portion 230 of blooming is smaller, then portion of blooming
230 are more easily stamped, but so that the intensity in portion 230 of blooming is too weak so that the intensity for being pressed together on product surface is relatively low, makes
Into riveting built on the sand, therefore, in the present embodiment, the opening angle θ of the notch 203 is 16 °, on the one hand causes portion 230 of blooming
Easy punching press deformation bending, on the other hand so that portion 230 of blooming is with larger width so that be pressed together on opening for product surface
The intensity of flower portion 230 is larger so that riveting is more firm.
It is more firm in order to rivet so that riveting is more firm, in one embodiment, as depicted in figs. 1 and 2, described
Length of the rake 220 in the axial direction of the body 200 is less than length of the notch 203 in the axial direction of the body 200
Degree.It should be understood that length of the notch 203 in the axial direction of the body 200 can be considered the depth of notch 203, for example, institute
State the depth that length of the rake 220 in the axial direction of the body 200 is less than notch 203, it should be understood that rake
220 enter rivet hole for introduction pipe body 200, and the length of such as rake 220 is too big, then tube wall 210 can not fully be abutted
Space is produced between the hole wall of rivet hole, tube wall 210 and hole wall so that riveted built on the sand, because the length of rake 220 is small
It is less than the length in portion 230 of blooming in the length of the depth of notch 203, that is, rake 220, when the portion of blooming 230 is pressed on production
During product surface, rake 220 is all located at the outside of rivet hole, that is, is connected to the surface of product, therefore, does not result in tube wall
Loosening is produced between 210 and the hole wall of rivet hole, tube wall 210 is fully connected to the hole wall of rivet hole so that riveting is more firm.
In order to which further such that riveting is more firm, in one embodiment, the notch 203 is in the body 200
Length and the length ratio of the body 200 on axial direction are less than 1/2nd, for example, the notch 203 is in the body 200
Axial direction on length ratio on abstract of length and the body 200 be less than 1/2nd.It should be understood that notch
203 depth is too big, and the intensity of tube wall 210 will be caused to reduce, and after the insertion rivet hole of body 200, notch 203 is as penetrated into rivet
In hole, it will make it that riveting is unstable, for example, length of the notch 203 in the axial direction of the body 200 and the body
200 length ratio is 1：(3~4), therefore, in the present embodiment, the ratio that the depth of notch 203 accounts for the length of body 200 is situated between
Between 1/3rd and a quarter so that tube wall 210 can fully be connected to the hole wall of rivet hole, it is to avoid the shadow of notch 203
The intensity that speaking pipe wall 210 is abutted with hole wall, and so that the easy punching press in portion 230 of blooming is bloomed so that riveting is more convenient.
In order that must rivet it is more firm, in one embodiment, circle of some notches 203 along the tube wall 210
Circumferential direction is uniformly arranged, and is set for example, the width of each notch 203 is identical, for example, on same axial location, it is each described
The width of notch 203 is identical, is set for example, the width in the portion 230 of blooming is equal, so that portion 230 of respectively blooming is in punching press
After can wash open well-balancedly, and be equably connected to product surface so that the uniform force of portion 230 of respectively blooming, and then cause riveting
It is more firm.
In order that must rivet it is more firm, for example, the quantity of the notch be four, for example, the quantity of the notch is
Five, for example, as depicted in figs. 1 and 2, the quantity of the notch 203 is six, it is worth mentioning at this point that, each notch 203 is located at
Between two portions 230 of blooming, the quantity of notch 203 is more, and the quantity of portion 230 of blooming is more, then the width in portion 230 of blooming is smaller, opens
The width in flower portion 230 is smaller, then intensity is lower so that the intensity that portion 230 of blooming is pressed on product surface declines, and is unfavorable for riveting
Stable, therefore, the quantity of notch 203 should not be excessive, and the quantity of notch 203 is also unsuitable very few, the quantity of notch 203 very little, then
The width in corresponding portion 230 of blooming is larger, is unfavorable in punching press, the present embodiment, and the quantity of notch 203 is six, is enabled to
Notch 203 is evenly distributed, and is conducive to carrying out punching press under less punching press dynamics, and so that the width in portion 230 of respectively blooming is fitted
In, product surface can be pressed on so that riveting is more firm.
In order that the second end 202 for obtaining tube wall 210 is easier deformation bending in punching press, for example, as shown in Fig. 2 described
The thickness of rake 220 gradually increases from one end close to second end 202 to one end close to the first end 201, example
Such as, the thickness of the rake 220 from close to the first end 201 one end to close to second end 202 one end gradually
Reduce, for example, the rake 220 has trapezoid cross section, for example, the rake 220 is in the axial direction of the body 200
Section is trapezoidal, and the thickness due to rake 220 close to the one end at the second end 202 is smaller so that rake 220 has less
Intensity, that is, the second end 202 of tube wall 210 have less intensity, are conducive to the Bending Deformation of the second end 202 of tube wall 210,
So that the second end 202 of tube wall 210 is easier deformation bending in punching press, and with close first end 201, rake 220
Thickness is larger, and thickness of the rake 220 close to one end of first end 201 is identical with the thickness at other positions of tube wall 210, because
This, with compared with strong hardness, can impermeable riveting in rivet hole so that riveting is more firm.
In order to which preferably riveting enters and reached safer riveting, for example, referring to Fig. 1 and Fig. 2, the rake 220 has
There is inclined plane 221, for example, the inclined plane 221 is the outer surface of the rake 220, for example, the rake 220 is
The conic tube on part top is amputated using the plane parallel to bottom surface；In one embodiment, the inclined plane 221 and the pipe
Angle α between the central axis of body 200 is 5 °~10 °, for example, on the section in the axial direction of body 200, inclined plane 221
Corresponding lines are formed on the section, the angle between the lines and central axis is inclined plane 221 and the body 200
Central axis between angle α, the angle α be inclined plane 221 angle of inclination, it should be understood that inclined plane 221 with pipe
Angle between the central axis of body 200 is too big, and the riveting of body 200 is entered to cause to hinder, is unfavorable for the guiding to body 200, and
Inclined plane 221 and the angle of the central axis of body 200 are too small, then inclined plane 221 is intended to the central shaft parallel to body 200
Line, then guide effect not good, in the present embodiment, because the angle α between the central axis of inclined plane 221 and body 200 is 5 °
~10 °, not only contribute to rake 220 and enter in rivet hole, also effectively make it that the length of rake 220 is longer, is conducive to pair
The guiding of body 200.
In order to which further the preferably riveting of introduction pipe body 200 enters rivet hole so that riveting is more quick, for example, described tilt
