In this embodiment, the spiral groove is integrally divided into a speed regulation section and a non-speed regulation section along the groove depth direction. The speed regulation section is arranged close to the cylindrical groove, the flow speed of the scroll blank in the scroll groove is regulated through the speed regulation section, and then the flow speeds of the scroll blank in all positions in the scroll direction are the same, so that the heights of the finally obtained scroll body in all points in the extension direction are consistent.
Specifically, referring to fig. 2 and 3, the spiral groove includes a plurality of sequentially connected profiled groove segments along the extending direction thereof, and each profiled groove segment is divided into a profiled groove segment speed regulation segment 20 and a profiled groove segment non-speed regulation segment 30 along the groove depth direction thereof. And the part of the vortex body corresponding to the molding groove section is a molding section. Each forming groove section speed regulating section 20 controls the flowing speed v of the scroll plate blank of the corresponding part, and then the corresponding forming section is obtained through forming.
The groove width B of each forming groove section speed regulating section 20 is not larger than the thickness of the forming section formed correspondingly, and the flow velocity v of the scroll blank in the groove depth direction is regulated by extruding each forming groove section speed regulating section 20. Further, the groove width B and the groove depth of each forming groove section speed regulating section 20 are different, and the groove depths (such as L1 and L2, L3 and L4, L5 and L6) of the inner side and the outer side of each forming groove section speed regulating section 20 are different, by adjusting the contact area of the scroll blank and the female die 2, the frictional force f1 and f2 between the die and the two sides of the scroll blank is further changed, the flow velocity v of each section forming part of the scroll is adjusted, and further the heights of the obtained scroll at each point in the extending direction are consistent, and due to the reduction of the frictional force between the die and the scroll blank, the requirement of forming on extrusion force is reduced, the extrusion force borne by the die is reduced, the service life of the die is prolonged, and the requirements on pressure and tonnage are also reduced.
In this embodiment, the specific groove depth of the speed regulating section 20 of each forming groove section is related to the wall thickness of the forming section, the shortest distance from the forming section to the center of the scroll body, and the material of the scroll body. The larger the wall thickness of the molding section is, the larger the groove depth of the molding groove section speed regulating section 20 is; the greater the shortest distance from the forming section to the center of the scroll, the smaller the groove depth of the forming groove section speed regulating section 20. The greater the plastic deformability of the material of the scroll, the smaller the groove depth of the profiled groove section speed regulation section 20.
The design principle of the groove width B of the forming groove section speed regulating section 20 is as follows: b1≤B≤b2. Wherein, b1Design of minimum limit dimension for wall thickness of profiled section, b2The maximum limit size is designed for the wall thickness of the profiled section. The basic wall thickness of the forming section is b, and according to design tolerance, the minimum limit wall thickness b can be obtained1And maximum wall thickness design limit dimension b2。

Under the condition that the wall thickness of the first forming section is equal to that of the second forming section, the design principle of the groove depths of the first forming section speed regulating section and the second forming section speed regulating section is as follows:
if the shortest distance from the first forming section to the center of the vortex body is greater than the shortest distance from the second forming section to the center of the vortex body, the groove depth of the speed regulating section of the first forming section is greater than that of the speed regulating section of the second forming section;
if the shortest distance from the first forming section to the center of the vortex body is smaller than the shortest distance from the second forming section to the center of the vortex body, the groove depth of the speed regulating section of the first forming section is smaller than that of the speed regulating section of the second forming section;
the arrangement ensures that the flow rates of the first forming section and the second forming section are close to each other, and finally the heights of the two forming sections are basically consistent.
In addition to the above design principle, the present embodiment considers three influencing factors, namely the wall thickness of the forming segment, the shortest distance from the forming segment to the center of the scroll body, and the material of the scroll body, and provides a general formula for the depth design of the forming groove segment speed adjusting segment 20: l-2 ub-kz. Wherein, L is the groove depth of the forming groove section speed regulating section 20, b is the wall thickness basic size of the forming section, z is the shortest distance from the forming section to the center of the vortex body, k is the distance influence coefficient, and u is the material influence coefficient.

For a vortex body made of 4 series aluminum alloy, the value range of the material influence coefficient u is 1.05-1.85. The dimension design of the vortex groove based on the formula ensures that the heights of all parts in the extending direction of the vortex body obtained by stamping are consistent, and the integral height difference is not more than 5 percent.

In addition, for the design of the groove width M of the molding groove section non-speed regulation section 30, the value range of M is: (B +0.1mm) to (B +0.6 mm). Wherein, B is the groove width of the forming groove section speed regulating section 20 corresponding to the forming groove section non-speed regulating section 30 in the same forming groove section. So set up, can guarantee that the blank through shaping groove section speed governing section 20 can get into shaping groove section non-speed governing section 30 smoothly to guarantee that the unloading rod 83 can upwards ejecting vortex dish work piece 1 smoothly.

When forging, the vortex plate blank is placed in the cylindrical groove of the combined female die 2, and the male die 1 moves downwards to forge and form the vortex plate blank. In the process, when the vortex plate blank flows downwards to the vortex groove of the female die 2 by means of plastic deformation, the metal flow speeds of different forming sections are adjusted through forming groove sections with different groove widths and groove depths, and finally the end face flatness of the vortex body is controlled to be more than 95% (equivalent to back pressure forming). And when the die descends to a set height, finishing the forging forming. And (3) opening the die, and pushing the ejector rod 82 upwards to drive the ejector rod tray 81 and the discharging rod 83 to ascend so as to eject the formed scroll workpiece 1.
