Abstract
The utility model discloses a car spoke nut extrusion forming die which comprises a lower die plate, a guide pillar, an upper die plate and a guide sleeve. A lower fixed base plate, a lower punch base plate and a lower punch fixed plate are successively installed on the lower die plate, the lower fixed base plate, the lower punch base plate and the lower punch fixed plate are positioned according to a lower center positioning pillar, and a lower punch is installed on the lower punch fixed plate. An upper fixed base plate, an upper punch base plate and an upper punch fixed plate are successively installed on the upper die plate, the upper fixed base plate, the upper punch base plate and the upper punch fixed plate are positioned according to an upper center positioning pillar, and an upper punch is installed on the upper punch fixed plate. The heads of the upper punch and the lower punch are both spherical heads which are adaptive to spoke nuts. The car spoke nut extrusion forming die can enable a plurality of double-faced nuts of spokes to be simultaneously formed once in extruded mode on a hydraulic machine, spherical surface roughness can achieve 6.3 micrometers, diameter tolerance of each nut is controlled no more than 0.3 millimeter, the diameter and the plane reference position degree of the plurality of double-faced nuts can be controlled no more than phi 0.3 millimeter relative to a distribution circle. Each nut is ensured to be concentric with a center hole and an outside diameter, and radial end jump of the spokes is within tolerance range.
Description
Technical field
The utility model relates to a kind of processing technology equipment, specifically a kind of automobile spoke nut extrusion molding dies.
Background technology
At present, the conventional fabrication and processing technology of automobile spoke is: blanking, and---------------ream ball bowl nut is bored in fraising---car---to multiple the pressure to compound dashing, and all locatees with screw when machined into centre bore and external diameter towards the wind hole in moulding; Because of the screw hole dimensions tolerance in 0～0.8mm scope, alignment pin size that sets and screw fit clearance inaccuracy cause the spoke dimensional tolerance range after the processing bigger; And nut single processing on drilling machine; The difference of machining benchmark finally causes nut and screwhole position degree overproof, and nut and centre bore, external diameter decentraction finally cause spoke directly to be held jumping overproof; The vehicle shake caused potential safety hazard when operation was used.
The utility model content
In order to overcome above-mentioned defective; The utility model provides a kind of automobile spoke nut extrusion molding dies; Can a plurality of nut time processing of spoke be formed; Guarantee that nut and centre bore, external diameter are concentric, for the following process assembling of spoke provides comparatively accurate localization benchmark, the footpath end jumping that guarantees spoke is within the margin of tolerance.
To achieve these goals, the technical scheme of the utility model is: a kind of automobile spoke nut extrusion molding dies comprises lower bolster, guide pillar, cope match-plate pattern, guide pin bushing; Fixedly backing plate is set down on the lower bolster; Fixedly on the backing plate low punch backing plate is set down, the low punch backing plate is provided with the low punch fixed head, and the low punch fixed head is provided with low punch; Fixedly backing plate, low punch backing plate, low punch fixed head center are provided with down the centralized positioning post down, and following centralized positioning post is the benchmark location; Fixedly backing plate is set under the cope match-plate pattern; Upward fixedly backing plate is divided into and is put the upper punch backing plate; The upper punch fixed head is set under the upper punch backing plate; The upper punch fixed head is provided with upper punch, and upward fixedly backing plate, upper punch backing plate, upper punch fixed head center are provided with the centralized positioning post, and above centralized positioning base for post certainly the position; Low punch head and upper punch head are all the ballhead that adapts with spoke nut.
The automobile spoke nut extrusion molding dies of the utility model; Can be with a plurality of two-sided nut once extrusion modling on hydraulic press simultaneously of spoke; The sphere roughness can obtain 6.3 μ m on the one hand; The nut diameter tolerance is controlled at≤0.3mm on the other hand, and a plurality of two-sided nuts can be controlled at≤φ 0.3mm with respect to distribution circle diameter and reference position, plane degree.Guarantee that nut and centre bore, external diameter are concentric, the footpath end jumping that guarantees spoke is within the margin of tolerance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is done explanation further.
As shown in Figure 1; The automobile spoke nut extrusion process device of the utility model comprises lower bolster 1, guide pillar 12, cope match-plate pattern 11, guide pin bushing 13, and fixedly backing plate 2 is set down on the lower bolster 1; Fixedly on the backing plate 2 low punch backing plate 3 is set down; Low punch fixed head 5 is set on the low punch backing plate 3, and low punch fixed head 5 is provided with the low punch hole, and the distribution circle diameter in low punch hole is identical with reference position, plane degree with the bolthole circle diameter of extruding spoke 14 with reference position, plane degree; The low punch hole low punch 4 of packing into; Low punch 4 and low punch hole interference fit, following fixedly backing plate 2, low punch backing plate 3, low punch fixed head 5 centers are provided with down centralized positioning post 15, and following centralized positioning post 15 is that reference center locatees;
Cope match-plate pattern is provided with fixedly backing plate 9 for 11 times; Going up fixedly, backing plate is provided with upper punch backing plate 89 times; The upper punch backing plate is provided with upper punch fixed head 78 times, and upper punch fixed head 7 is provided with the upper punch hole, and the distribution circle diameter in upper punch hole is identical with reference position, plane degree with the bolthole circle diameter of extruding spoke 14 with reference position, plane degree; The upper punch hole upper punch 6 of packing into; Upper punch 6 and upper punch hole interference fit, upward fixedly backing plate 9, upper punch backing plate 8, upper punch fixed head 7 centers are provided with centralized positioning post 10, and above centralized positioning post 10 is the reference center location.Low punch 4 heads and upper punch 6 heads are all the ballhead that adapts with spoke nut.
Following fixedly backing plate 2 and lower bolster 1, low punch backing plate 3 and following fixedly backing plate 2, low punch fixed head 5 and low punch backing plate 3; Be connected with interior six square bolts with alignment pin respectively; And with descending reference column 15 that it is combined; Low punch 4 is packed into interference fits in the low punch fixed head 5, constitutes the extruding counterdie.Go up fixedly backing plate 9 and cope match-plate pattern 11, upper punch backing plate 8 and last fixedly backing plate 7, upper punch fixed head 7 and upper punch backing plate 8; Be connected with interior six square bolts with alignment pin respectively; And use reference column 10 it is combined; Upper punch 6 is packed into interference fits in the upper punch fixed head 7, constitutes the extruding patrix.Cope match-plate pattern 11 is settled guide pillar 12 and guide pin bushing 13 with lower bolster 1, and the extruding upper and lower mould leans on guide pillar 12 and guide pin bushing 13 to constitute a whole set of extrusion die.
The technical scheme of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical scheme of the utility model all falls within the protection domain of the utility model.
