Description
Technical field
The utility model relates to the production equipment of a kind of automotive seat with profiled holes on the elongated tubular, a kind of specifically elongated tubular middle part punching die.
Background technology
Since the reform and opening-up, particularly the Domestic Automotive Industry growth momentum is powerful in recent years, China become continue U.S., day after the 3rd automobile produce the country of breaking ten million per year, enter ten million automobile superpower ranks.In order to satisfy the requirement of this fast development of automobile industry, the auto parts and components that play a decisive role for the speed of production and the quality of the automobile producer that forms a complete production network, the structure of the parts of being produced, quality and quantitative requirement are more and more higher.
In automotive seat is produced, elongated tubular is a kind of more common processing component, and original elongated tubular becomes hole tool to adopt boring grab to hole on drilling machine substantially, and this technology once can only be bored a circular hole, efficient is low, waste man-hour, labour intensity is big, and the finished product burr is big, reprocess easily, mismachining tolerance is big, and the percent defective height has significant limitation.
Summary of the invention
The purpose of this utility model is to provide a kind of simple and reasonable, and efficient is low, and labour intensity is little, and mismachining tolerance is little, the elongated tubular middle part punching die that percent defective is low.
The purpose of this utility model is to realize like this, this punching die comprises cope match-plate pattern, punch retainer, punch, lower bolster, mandrel die fixed block, mandrel die, microgap support iron and locating piece, described punch is arranged on the cope match-plate pattern by punch retainer, mandrel die fixed block is arranged on an end of lower bolster, the microgap is supported iron and is arranged on the lower bolster, described locating piece is fixed on the mandrel die fixed block, and the mandrel die is arranged on mandrel die fixed block and the microgap is supported on the iron.
The utlity model has following advantage:
1, the utility model mould can be according to the various profiled holes on the product needed stamping-out elongated tubular, can be once towards a plurality of holes of different angles different size, and the efficient height has reduced labour intensity, and finished product does not have burr, can rational and effective guarantee product quality.
2, the utility model mould is used for elongated tubular middle part towards circular hole, square hole, profiled holes etc., can divide a plurality of stations once towards a plurality of holes of different angles on a mold.
3, during the utility model mold work, when contacting with workpiece, punch can produce very big blanking pressure, can make the mandrel die of long cantilever produce very big flexural deformation, and this mould is offset blanking pressure by supporting the iron supporting workpiece with the microgap, the pressure distortion amount that makes the generation of mandrel die so just makes this mould reach the punching purpose of elongated tubular in the scope of reasonable stamping-out.
4, the utility model mould punch adopts the drift of oblique processing, can reduce the stamping-out contact area effectively, thereby blanking pressure is reduced greatly, and the pressure that the mandrel die is born reduces, and elongated tubular middle part punching can more reasonably be realized.

The specific embodiment
Shown in accompanying drawing 1,2,3: this punching die comprises cope match-plate pattern 1, punch retainer 2, punch 3, lower bolster 4, mandrel die fixed block 5, mandrel die 6, microgap support iron 7 and locating piece 8, described punch 3 is arranged on the cope match-plate pattern 1 by punch retainer 2, mandrel die fixed block 5 is arranged on an end of lower bolster 4, the microgap is supported iron 7 and is arranged on the lower bolster 4, described locating piece 8 is fixed on the mandrel die fixed block 5, and mandrel die 6 is arranged on mandrel die fixed block 5 and the microgap is supported on the iron 7.
Shown in accompanying drawing 3: an end is uniform side by side on the described lower bolster 4 is provided with a plurality of mandrel die fixed blocks 5, corresponding each mandrel die fixed block 5 side by side is provided with a microgap at least and supports iron 7, and each mandrel die fixed block 5 and the microgap that is arranged side by side with it are supported iron 7 and formed a processing stations I, II, III.
The quantity that punch retainer 2 is set on the described cope match-plate pattern 1 is corresponding with the microgap support iron 7 on position and the lower bolster 4.
Have a plurality of processing stations I, II, III that be arranged in parallel between described cope match-plate pattern 1 and the lower bolster 4.
Shown in accompanying drawing 4: described mandrel die 6 is the long cylinder structure, and an end is a stiff end 13, has die hole 14 on it.
Shown in accompanying drawing 5: described punch 3 cutting edges are inclination cutting edge structures.
The mold work principle:
The utility model mould punch 3 is fixed on the forcing press on the plane by punch retainer 2 and cope match-plate pattern 1, and mandrel die 6 is fixed on the forcing press lower plane by mandrel die fixed block 5 and lower bolster, is in open mode when not working.During work, earlier workpiece 9 is inserted on the mandrel die 6 of station I, fix the end position of workpiece 9 by locating piece 8, start forcing press, when bolster 1 and 4 compresses along with forcing press, workpiece 9 will form the hole that requires shape along with the stamping-out of punch 3 and mandrel die 6, stamping-out forms the technology locating notch of end simultaneously, take out workpiece 9 when bolster 1 with when opening in 4 minutes, insert again in the mandrel die 6 of station II, and the technology locating notch by the end is fixed on and carries out the stamping-out second time on the locating piece 8, can obtain required final products by that analogy.
