Abstract
The utility model discloses a spin pressing and forming die set for a wide flange cylindrical piece, which comprises an upper die, a lower die, as well as a performing spinning wheel and a final forming spinning wheel, which are used to match the upper die and the lower die, wherein a positioning column is fixedly mounted in the center part at the upper end of a lower die, the upper surface of the lower die is a forming surface matched with the inner surface of the wide flange cylindrical piece, a round hole is formed in the center part of the lower end of the upper die, the flange of the performing spinning wheel is a large arc surface, the radius of the large arc surface is not less than two times of the blank thickness of the wide flange cylindrical piece, the flange of the final forming spinning wheel is a small arc surface, and the radius of the small arc surface is matched with the circle radius of the joint of the cylinder wall of the wide flange cylindrical piece and the flange. Compared with die cut forming, the spin pressing and forming of the spin pressing and forming die set has the advantages that the production efficiency, the material utilization ratio and the product quality are improved, and the tool manufacturing cost and the manufacturing period are reduced.
Description
Technical field
The utility model relates to the technological equipment field, relates in particular to a kind of wide flange cylindrical member and presses and revolve the mould group.
Background technology
Wide flange cylindrical member moulding prior art is generally that steel plate is cut material, then adopt punch press through three times or stretch more frequently after trimming form, not only the punch die manufacturing cost is high, the cycle is long for such mode of production, and production efficiency and stock utilization all lower.
Summary of the invention
For addressing the above problem, a kind of wide flange cylindrical member of the present utility model is pressed and is revolved the mould group, steel plate is cut into adopts the vertical spinning machine that workpiece is once pressed after the disc blank to revolve moulding, enhances productivity and the purpose of stock utilization to reach.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of wide flange cylindrical member of the utility model is pressed and is revolved the mould group, comprise patrix, counterdie and the preformed spinning roller and the final shaping unit spinning roller that are mated use, a locating dowel is installed in the centre, upper end of described counterdie, the upper surface of counterdie is the forming surface that is complementary with wide flange cylindrical member inner surface, the centre bore of described locating dowel and wide flange cylindrical member blank is for movingly, and the centre, lower end of described patrix is provided with circular hole, and described circular hole and locating dowel are for movingly.
Further improvement of the utility model is: the wheel rim of described preformed spinning roller is the great circle cambered surface, and the radius of described great circle cambered surface is not less than two times of wide flange cylindrical member sotck thinkness.
Further improvement of the utility model also is: the wheel rim of described final shaping unit spinning roller is small arc surface, and the barrel of the radius of described small arc surface and wide flange cylindrical member and flange junction arc radius are complementary.
The beneficial effects of the utility model are: compare with the stamping-out moulding and make not only that production efficiency improves more than three times, stock utilization improves more than 5% installing and using the utility model on spinning machine, and the manufacturing cost of frock, manufacturing cycle reduce more than 50%, also improved product surface roughness and material structure density.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In order to deepen that understanding of the present utility model is further described the utility model below in conjunction with embodiment and accompanying drawing, this embodiment only is used for explaining the utility model, does not consist of the restriction of the utility model protection domain.
as shown in Figure 1: a kind of wide flange cylindrical member of the present utility model is pressed and is revolved the mould group, comprise patrix 1, counterdie 2 and the preformed spinning roller 5 and the final shaping unit spinning roller 7 that are mated use, a locating dowel 3 is installed in the centre, upper end of counterdie 2, the upper surface of counterdie 2 is the forming surface 4 that are complementary with wide flange cylindrical member inner surface, the centre bore of locating dowel 3 and wide flange cylindrical member blank 5 is for movingly, the centre, lower end of described patrix 1 is provided with circular hole 10, described circular hole 10 and locating dowel 3 are for movingly, the wheel rim of described preformed spinning roller 6 is great circle cambered surfaces 8, the radius of described great circle cambered surface 8 is not less than two times of wide flange cylindrical member blank 5 thickness, the wheel rim of described final shaping unit spinning roller 7 is small arc surfaces 9, the barrel of the radius of described small arc surface 9 and wide flange cylindrical member and flange junction arc radius are complementary.
when the utility model is implemented, operating personnel are fixedly installed to patrix 1 on the top pressure part of vertical spinning machine, counterdie 2 is fixedly installed on the spindle unit of vertical spinning machine, again preformed spinning roller 6 and final shaping unit spinning roller 7 are fixedly installed to respectively on the radial direction mechanism parts of vertical spinning machine worktable both sides, the centre bore of wide flange cylindrical member blank 5 is nested on locating dowel 3, then start the vertical spinning machine, clamped rear spindle unit fast rotational with the vertical spinning machine at wide flange cylindrical member blank 5 by patrix 1 and counterdie 2, simultaneously preformed spinning roller 6 applies radially and downward power for wide flange cylindrical member 5 blanks by the great circle cambered surface 8 of wheel rim under the effect of radial direction mechanism parts simultaneously, after being processed into the splayed semi-finished product, preformed spinning roller 6 withdraws from, final shaping unit spinning roller 79 pairs of splayed semi-finished product of small arc surface by wheel rim under the effect of radial direction mechanism parts apply radially and downward power simultaneously, make it be processed into the finished product of wide flange cylindrical member to the forming surface 4 pointwise continuous modifications of counterdie 2.
After the utility model is implemented, compare with the stamping-out moulding and make not only that production efficiency improves more than three times, stock utilization improves more than 5%, and the manufacturing cost of frock, manufacturing cycle reduce more than 50%, also improved product surface roughness and material structure density.
