Abstract

The utility model discloses a special necking and arc-surface shaping die for the lower pressure plate of the lower support of an automobile shock absorber. The die is convenient to adopt the stamping method to implement the workpiece necking technology, achieves the shaping of products at the same time, improves the processing efficiency and the product quality, ensures the stability of the product quality and reduces the processing difficulty. An upper die assembly comprises an upper die plate, a female die, a die handle and a material knocking rod, wherein the female die is fixedly connected with the upper die plate; a processing groove which corresponds to an upper opening of a processed workpiece in shape is formed on an upper die (i.e. the female die); and the diameter of the lowest end of the processing groove is equal to the outside diameter of the upper opening of an unprocessed workpiece. A lower die assembly comprises a lower die plate, a lower pressure plate, an upper pressure plate, a elastic padding plate, a male die and a guide post, wherein the lower pressure plate is fixedly connected with the lower die plate; the elastic padding plate is arranged on the lower pressure plate; the upper pressure plate is arranged on the elastic padding plate; the guide post penetrates the upper pressure plate and the elastic padding plate and then is fixedly connected with the lower pressure plate; the male die is mounted in the centers of the upper pressure plate and the elastic padding plate; and the upper end surface of the male die is propped against the arc surface of the unprocessed workpiece.

Description

Lower platen necking down of automobile absorber undersetting and arc surface shaping particular manufacturing craft
Technical field
The utility model relates to a kind of automobile absorber undersetting lower platen arc surface shaping particular manufacturing craft.
Background technology
In the process that automobile product updates, automobile absorber undersetting lower platen need carry out again Design and Machining to adapt to the requirement of Product Renewal.Newly-designed automobile absorber undersetting lower platen need carry out necking down and shaping to the intermediate member that is processed in process.Present necking down processing method is that lateral compression or spinning form, and in this processing method, because extruding or the employed die of spinning need divide some lobes to form the upper surface annular groove, convex line appears in the annular groove outer surface, and working (machining) efficiency is low, quality is unstable.And, can not reach the purpose of shaping simultaneously, the product difficulty of processing is big.
The utility model content
The utility model is in order to overcome weak point of the prior art; A kind of automobile absorber undersetting lower platen necking down and arc surface shaping particular manufacturing craft are provided; So that the necking down processing technology of workpiece adopts the method for punching press to realize, and realize simultaneously the shaping of product improving working (machining) efficiency and product quality; Ensure the stability of product quality, reduce difficulty of processing.
The utility model is realized through following technical proposals:
A kind of automobile absorber undersetting lower platen necking down and arc surface shaping particular manufacturing craft; It is characterized in that; Comprise mould assembly and lower mould assembly, the said mould assembly of going up comprises cope match-plate pattern, die, die shank and knockout rod, and said die is fixedly connected with cope match-plate pattern; Said patrix is provided with and processes the corresponding working groove of back workpiece upper shed shape, and the diameter bottom of said working groove is identical with the preceding workpiece upper shed external diameter of processing; Be fixed with die shank on the said cope match-plate pattern, said knockout rod passes said die shank, cope match-plate pattern, die; Said lower mould assembly comprises lower bolster, lower platen, top board, resilient sleeper-bearing, punch, lead; Said lower platen is fixedly connected with said lower bolster; Be placed with resilient sleeper-bearing on the said lower platen; Be placed with top board on the said resilient sleeper-bearing, said lead passes said top board, resilient sleeper-bearing is fixedly connected with said lower platen, and said punch is installed in top board and resilient sleeper-bearing center; The arc surface of the preceding workpiece of processing is withstood in the upper surface of said punch, and said cope match-plate pattern and lower bolster are slidingly connected through the guide pillars and bushes that matches.
The utlity model has following technique effect:
The particular manufacturing craft of the utility model makes the necking down processing technology of workpiece adopt the method for punching press to realize, and in necking down, realizes the shaping of product, improves working (machining) efficiency and product quality, ensures the stability of product quality, has reduced the product difficulty of processing.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
The sketch map of lower platen necking down of the utility model automobile absorber undersetting and arc surface shaping particular manufacturing craft is as depicted in figs. 1 and 2; Comprise mould assembly and lower mould assembly; The said mould assembly of going up comprises cope match-plate pattern 2, die 5, die shank 3 and knockout rod 4; Said die 5 is fixedly connected with cope match-plate pattern 2, and said upper cavity die 5 is provided with and processes the corresponding working groove 12 of back workpiece upper shed shape, and the diameter bottom of said working groove is identical with the preceding workpiece upper shed external diameter of processing.Be fixed with die shank 3 on the said cope match-plate pattern 2, said knockout rod 4 passes die shank 3, cope match-plate pattern 2, die 5.Said lower mould assembly comprises lower bolster 11, lower platen 9, top board 7, resilient sleeper-bearing 6, punch 8, lead 10; Said lower platen 9 is fixedly connected with lower bolster 11; Be placed with resilient sleeper-bearing 6 on the lower platen 9; Be placed with top board 7 on the resilient sleeper-bearing 6, lead 10 passes top board 7, resilient sleeper-bearing 6 is fixedly connected with lower platen 9.Said punch 8 is installed in top board 7 and resilient sleeper-bearing 6 centers, and the arc surface of the preceding workpiece of processing is withstood in the upper surface of said punch 8, and said cope match-plate pattern 2 is slidingly connected with guide pin bushing 13 through the guide pillar 1 that matches with lower bolster 11.Wherein, resilient sleeper-bearing preferably adopts elastomeric material.
Fig. 3 is the sketch map before the workpiece processing, and Fig. 4 is the sketch map of workpiece after processing.During use; The arc surface 15 of workpiece 14 is placed on the punch; Power-equipment drives cope match-plate pattern and die moves down; The lower surface of working groove is blocked workpiece upper shed and limiting material and is realized necking down processing along working groove on the die, and necking down makes the arc surface 15 among Fig. 3 become shape shown in Figure 4 simultaneously, realizes the shaping of arc surface.
