Abstract
The utility model discloses a novel mould of terminal overlap of spinning hub structure is improved. The more traditional mould lower mould of this mould bottom has increased the lower mould and has improved regional 7, the lower mould improves 7 regional tops design and levels up metal water conservancy diversion platform 6, this horizontal metal water conservancy diversion platform 6 has changed the tradition and has cast the overlap metal flow direction when aluminum alloy hub blank spinning is extremely terminal soon, change into radial overlap by former axial overlap, the problem of lead to blank downward heat treatment furnace that directly get into of rim in unable because the overlap height differs is solved, to cancel machine tooling preface in advance significant to realizing casting the short flow production of aluminum alloy hub soon.
Description
Technical field
The utility model relates to mould, relates in particular to a kind of casting and revolves aluminium alloy wheel hub spinning mold.
Background technology
Casting is revolved aluminium alloy wheel hub and is carried out short route production namely: the blank manufactured by low-pressure casting process, and band rising head directly carries out preheating, spinning, and after spinning, blank inner rim directly enters roll body formula heat-treatment furnace downwards.By the impact of existing equipment and mould and die accuracy, conventional boss spinning process, blank spinning, to wheel lip place together, all can form the axial overlap that height is uneven, cause blank cannot enter downwards roll body formula heat-treatment furnace by inner rim.
Summary of the invention
The purpose of this utility model is to provide a kind of solution and revolves during aluminium alloy wheel hub short route produces in casting, and after spinning, blank cannot directly enter the device of roll body formula heat-treatment furnace downwards by inner rim.
The technical solution of the utility model is: increase horizontal metal guide platform bottom counterdie.
The radial distance that described horizontal metal guide platform revolves aluminium alloy wheel hub inner rim product line with casting is more than or equal to 13 millimeters, and is less than or equal to spinning machine running roller and counterdie and improves the radial spacing that aluminium alloy wheel hub inner rim product line is revolved in region interference point and casting.
The axial distance that described horizontal metal guide platform revolves aluminium alloy wheel hub inner rim product line with casting is more than or equal to 11 millimeters, and is less than or equal to spinning machine running roller and counterdie and improves the axial spacing that aluminium alloy wheel hub inner rim product line is revolved in region interference point and casting.
The utility model counterdie horizontal metal guide platform applies the restriction of axial direction to blank, forms plane after making blank spinning in inner rim position, and then cannot directly enter the problem of roll body formula heat-treatment furnace downwards by inner rim after solving blank spinning.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Fig. 1 is that in prior art, aluminium alloy wheel hub lower die of spinning die partial schematic diagram is revolved in casting; Fig. 2 is a kind of Novel die structure schematic diagram improving spinning wheel hub end overlap of the utility model; Aluminum alloy hub blank is revolved in 1-casting, 2-prior art spinning counterdie, the axial overlap that 3-prior art blank spinning produces to end, 4-spinning machine running roller, 5-modified spinning counterdie, the horizontal metal guide platform increased bottom L1-counterdie revolves the radial distance of aluminium alloy wheel hub inner rim product line with casting, the horizontal metal guide platform increased bottom L2-counterdie revolves the axial distance of aluminium alloy wheel hub inner rim product line with casting, 6-horizontal metal guide platform, 7-counterdie improves region, 8-spinning machine running roller and counterdie improve region interference point, the radial overlap of 9-.
Detailed description of the invention
As shown in Figure 2, after modified spinning counterdie 5 increases horizontal metal guide platform 6 bottom counterdie, use spinning machine running roller 4 to revolve aluminum alloy hub blank 1 to casting and carry out rotary pressing processing, radial overlap 9 can be produced at spinning end.This radial overlap 9 is opposite planar in the axial direction, therefore can meet casting and revolve aluminum alloy hub blank 1 inner rim and directly enter roll body formula heat-treatment furnace downwards.
As shown in Figure 2, a kind of modified spinning of the utility model die structure, the radial distance L1 that the horizontal metal guide platform 6 increased bottom described counterdie revolves aluminium alloy wheel hub inner rim product line with casting is more than or equal to 13 millimeters, and is less than or equal to spinning machine running roller and counterdie and improves the radial spacing L1 ' that aluminium alloy wheel hub inner rim product line is revolved in region interference point 8 and casting; Radial distance L1 crosses conference and causes spinning machine running roller and counterdie to improve region interfering in advance, cannot spinning to blank end, apart from the too small effect cannot playing axial constraint to blank, again form axial overlap.
As shown in Figure 2, a kind of modified spinning of the utility model die structure, the axial distance L2 that the horizontal metal guide platform 6 increased bottom described counterdie revolves aluminium alloy wheel hub inner rim product line with casting is more than or equal to 11 millimeters, and is less than or equal to spinning machine running roller and counterdie and improves the axial spacing L2 ' that aluminium alloy wheel hub inner rim product line is revolved in region interference point 8 and casting; The excessive effect cannot playing axial constraint to overlap of axial distance L2, forms axial overlap again, and too small meeting causes spinning machine running roller and counterdie to improve region interfering in advance, cannot spinning to blank end.
The utility model counterdie horizontal metal guide platform 6 revolves to casting aluminum alloy hub blank 1 to apply axial direction restriction at the radial overlap 9 that tail end produces, thus well solve casting revolve aluminium alloy wheel hub short route produce in, blank, under the prerequisite of not removing cast gate, cannot directly enter the problem of roll body formula heat-treatment furnace downwards by inner rim.
One described in the utility model changes end metal and flows to mode; horizontal metal guide platform 6 is increased bottom counterdie; be not limited to the elaboration that utility model content and detailed description of the invention are done; according to other end metal flow guide systems that the utility model religious doctrine is taked, all fall into protection domain of the present utility model.
Claims (4)
1. improve a Novel die structure for spinning wheel hub end overlap, it is characterized in that: bottom counterdie, increase horizontal metal guide platform (6).
2. according to a kind of Novel die structure improving spinning wheel hub end overlap according to claim 1, it is characterized in that: the horizontal metal guide platform (6) increased bottom counterdie change tradition casting revolve aluminum alloy hub blank spinning to overlap metal flow during tail end to, change radial overlap into by axial overlap.
