Description

Connect aerofoil profile saddle bracket forge die
Technical field
The utility model relates to saddle bracket manufacturing technology field.
Background technology
Saddle bracket is a vitals in Messenger Wire base, and it plays the effect of direct carrying carrier cable.National standard " parts of electrified railway contact network " is described to some extent to the structure of Messenger Wire base in (TB/T2075-2010), for single groove Messenger Wire base, the main body of its saddle bracket is a saddle-shaped line holder, respectively there is a leg-of-mutton connecting wing both sides of line holder, there is a circular hole running through from top to bottom at Xian Tuo center, respectively has a connecting hole in connecting wing.When use, line ball clamping plate, carrier cable, saddle bracket, Messenger Wire base body stacked successively and fix with bolt, wherein carrier cable passes through from saddle-shaped line holder just.
Under prior art, the production that connects aerofoil profile saddle bracket is to adopt mould forging and stamping to manufacture, before forging and stamping, first calculate the specification of blank used according to the drawing of saddle type bearing, then by blank heating, put it into again in special mould, forge and press with forging press, thereby obtain the forging and stamping blank of saddle type bearing.
Because blank generally adopts cylinder blank, and the tip portion of connecting wing is thinner and far away apart from center, therefore while forging and stamping, often produce the incomplete phenomenon of the most advanced and sophisticated moulding of connecting wing, in order to address this problem, conventionally before formal forging and stamping, increase blocking operation one, blocking is to adopt larger cylinder blank, and extrude a winglet extending to both sides in the centre of this blank, owing to having increased by a procedure, and blank consumption increases, just make whole production process become comparatively complicated, energy consumption is also large, forging cost increases, simultaneously, owing to having increased prefabricated blank operation, in whole production process, just need to repeatedly suppress the blank after heating, thereby cause the sharply decline of blank temperature, this has also affected the final performance of part.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of aerofoil profile saddle bracket forge die that connects is provided, it can make blank flow to the position of needs, the main body and the connecting wing that ensure the rear saddle bracket of forging and stamping are all full complete, thereby save blocking operation, save blank, enhance productivity.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of aerofoil profile saddle bracket forge die that connects, it comprises upper die and lower die, patrix has the upper impression identical with the upper profile shape of saddle bracket, counterdie has the lower impressions identical with the lower profile shape of saddle bracket, the edge of upper impression and lower impressions is all surrounded with stitching surface, patrix stitching surface is identical with the shape of counterdie stitching surface, when compressing, upper and lower mould has the gap of flowing out for clout between patrix stitching surface and counterdie stitching surface, upper die and lower die also have the overflow launder for holding clout, overflow launder is looped around outside stitching surface, counterdie has four overflows and stops projection, overflow stops that projection is positioned at four angle positions that connecting wing and saddle bracket main body are, these four overflows stop that projection can limit blank from the both sides of connecting wing and flow out the both sides of saddle bracket main body, make blank to the tip of connecting wing and the two ends of saddle bracket main body flow, ensure that these four position moulding are complete full, patrix has with overflow and stops the groove that projection matches, when upper and lower mould pressing, overflow stops between projection and groove to have gap.
As preferably, overflow stops that projection is between overflow launder and stitching surface.
As preferably, when upper and lower mould pressing, overflow stops between the side of projection and end face and groove all have the gap of 2 millimeters, and when forging and stamping, unnecessary blank can flow out from this gap.
As preferably, four jiaos of counterdie have guide pad, and four jiaos of patrix have the guide pad groove suitable with guide pad, and guide pad and guide pad groove limit the relative position of upper and lower mould jointly, ensure that both can not misplace.
As preferably, overflow stops that projection is four prism type, and its length is 15~40 millimeters, and width is 10~30 millimeters, is highly 6~20 millimeters.
As preferably, the material of upper die and lower die is H13 steel (H13 steel is the hot die steel that in GB/T1299-2000 standard, the trade mark is 4Cr5MoSiV1).
The beneficial effect that adopts technique scheme to produce is: the utility model adds overflow to stop projection in mould, can limit whens forging and stamping blank from connecting wing both sides and the both sides of saddle bracket main body flow out, thereby make blank to the tip of connecting wing and the two end portions of saddle bracket main body flow, after guarantee forging and stamping, especially connecting wing is full complete for the each several part of saddle bracket, save blocking operation, save blank, enhance productivity, very practical.
