The barrel of dynamic die is located between centring ring and jumping-up ring.
A kind of wall thickness is more than the sheet product upsetting-extruding method of flange thickness, and it comprises the steps,
1) first pass through the drawing punching technology of routine or drawing piercing and flanging technique makes sheet metal with flange
The cylindrical member prefabricated blank waiting wall thickness or the wall thickness such as approximate；
2) prefabricated blank of equal thickness is inserted on the rigidly connected core with lower template, cope match-plate pattern is descending, drives floating recessed
It is molded the flange of tight prefabricated blank and so that push rod is gradually resetted, centring ring play the guiding role to floating cavity die in the process；
3) cope match-plate pattern continues traveling downwardly, and jumping-up ring affixed therewith, with core for guiding, carries out jumping-up to the barrel of prefabricated blank,
Until full of the annular region between core and floating cavity die；
4) upper mould lifts, and jumping-up ring is up therewith with floating cavity die, and knock-pin is by the thick workpiece of barrel jumping-up from core
Ejection.
It is an advantage of the invention that first, compared with traditional machining process, the method being provided with the present invention and frock
Make the sheet metal part that wall thickness is more than flange thickness, its stock utilization greatly improves, and machining man-hour is obvious
Reduce, there is significant economic benefit；Second, bowl wall portion is after jumping-up, its mechanical property is due to work-hardening effect
And obtain different degrees of lifting, the bearer properties of workpiece can be made to obtain and to improve；Third, the technology of present invention offer and device,
Can be used not only for revolving parts makes the making it is also possible to for non-revolved body section parts.

Specific embodiment
With reference to the accompanying drawings and examples the present invention is described in detail：
The know-why of the present invention is, using the combination process of a kind of drawing punching and jumping-up, to complete wall thickness and be more than
The making of the tubular class stamping products of flange thickness.Metal plate the wall thickness or the tubular of the wall thickness such as approximate such as is made by drawing punching
Part prefabricated blank, the wall thickness of this prefabricated blank is increased to design requirement (more than flange thickness) by jumping-up.
A kind of wall thickness be more than flange thickness sheet product upsetting squeeze device include core 1, centring ring 2, jumping-up ring 3,
Floating cavity die 4, push rod 6, lower template 7 and cope match-plate pattern 8.Its annexation is as shown in Figure 1.Jumping-up ring 3 and cope match-plate pattern 8 are fixed in one
Rise, core 1 and centring ring 2 are arranged in lower template 7, floating cavity die 4 be hollow tubular and be located at lower template 7 and cope match-plate pattern it
Between, the barrel of floating cavity die 4 is located between centring ring 2 and jumping-up ring 3.
It is capable of the making that wall thickness is more than the tubular class stamping products of flange thickness, concrete step by said apparatus
Suddenly as follows：
1) first pass through the drawing punching technology of routine or drawing piercing and flanging technique makes sheet metal with flange
The cylindrical member prefabricated blank waiting wall thickness or the wall thickness such as approximate, as shown in Figure 2；
2) prefabricated blank of equal thickness is inserted on the rigidly connected core with lower template, cope match-plate pattern is descending, drives floating recessed
