State.Thus will also realize that formal forming process is the most stably carried out.In Figure 11 (d), it is known that in two positions of corner part 1c
It is formed well and is turned back what flange was constituted for a pair by stretch out the most laterally from the adjacent longitudinal wall 1b of four limit cartridge units
Flank 1g.I.e., it is not necessary to corner part 1c is carried out drawing and forming, only it is bent and deformed and just can form four limit cartridge units.Therefore,
Even if the forming height of four limit cartridge units uprises, the drawing resistance for blank material 1 also will not increase, in other words, it is not necessary to increases
The deflection adding each several part just can obtain the four limit cartridge units (having bottom tube-like parts) without fracture.But, in present embodiment 2
In the case of, owing to being provided with multiple flank 1g, therefore on the mould the least for turning R (drift 3 and punch die 4) under overlooking
In the groove 4f of the corner part 4c of punch die 4, the gap enlargement between drift 3 and punch die 4.Accordingly, there exist stamping after flank
The problem that the shape of 1g cannot be formed sharply as the shape of embodiment 1.Such flank 1g is formed wanting
In the case of more sharp-pointed, need embodiment 3 as be described hereinafter like that and turning R is correspondingly set to slightly by the quantity of flank 1g
Greatly.It addition, at above-mentioned two flank 1g under side-looking along with being gradually increased towards the open side of longitudinal wall 1b from bottom 1a, and
And under being also not provided with on flank 1g overlooking at two, extend prominent flange towards outside from the open end of flank 1g.

Sample is provided with the situation of flank 1g at corner part 1c and compares, it is possible to reduce the overhang of flank 1g.It is therefore preferable that be arranged on
The quantity of the flank 1g of corner part 1c be at two more than.But, if increasing the flank 1g being arranged at corner part 1c as described above
Quantity, then the end in the direction, inner side of the corner part 4c towards punch die 4 in groove 4f is overlapping, at such position, drift 3 with
Gap enlargement between punch die 4, therefore the shape of flank 1g cannot be stably formed.If it addition, the width of constriction groove 4f and make
The described end of groove 4f is the most overlapping, then the volume of the part bearing deformation load also diminishes, and the intensity of punch die 4 guarantees to become class
Topic.If wanting to guarantee to a certain extent the width of groove 4f, form more sharp-pointed flank 1g, then necessary and rib according to requirement
The radius of curvature R of corner part 4c is correspondingly set as bigger by the quantity of portion 1g.In other words, if the quantity of flank 1g is very few,
Then flank 1g increases from corner part 1c towards the overhang in inner side or outside, if the quantity of flank 1g is too much, then overlooks lower turning
The radius of curvature R of portion 4c increases.Here, turning R smaller from the viewpoint of shape restriction, inner capacities guarantee is (bent
Rate radius R is of about below 80mm), and, in order to obtain flank 1g towards little four limits of the overhang of outside product or inner side
Cartridge unit (has bottom tube-like parts), the quantity of the flank 1g being preferably disposed on corner part 1c be everywhere below.
As above, according to the structure of the present invention, not only need not two moulds (punch die and drift) be implemented respectively in pairs
Particular job, it is also possible to use can shape from the mass-produced cold stamping of blank material, only shaped by general curved
