Description

The outer edger of a kind of rubber ring

Technical field

The utility model relates to the rubber ring of pharmaceutical freeze-dried powder container barrel lid to be produced, and glue limit, cushion rubber outer ring accurately can be excised, thereby effectively guaranteed the complete of working face by this edger, relates in particular to the outer edger of a kind of rubber ring.

Background technology

Medicinal rubber circle flash trimming mode, for cutting by hand limit, is cut the edge out-of-flatness of the not high easy generation outer ring of limit precision now, also can cause product to cross and cultrate into waste product, production inefficiency.

Summary of the invention

The technical problems to be solved in the utility model is to provide the outer edger of a kind of rubber ring, it effectively raises the efficiency of medicinal rubber circle trimming operation, guarantee cushion rubber trimming quality, trimming precision improves greatly, has promoted product percent of pass, production efficiency, reduction labour intensity simultaneously, has improved product quality.

The purpose of this utility model is achieved in that

The outer edger of a kind of rubber ring, it comprises lower bolster, cope match-plate pattern, punch, die, tapered sleeve, main spring, guide pillar, guide pin bushing, punch retainer, ladder screw, die shank, stripper, stripper spring, upper pin and lower bearing pin, in die die cavity, be provided with buffer board, between buffer board and lower bolster, be provided with buffer spring, between buffer board and lower bolster, be connected by screw, in the positioning ring groove on buffer board, be provided with retaining ring.

Between above-mentioned guide pillars and bushes, be provided with steel ball retainer, steel ball retainer is withstood in main spring upper end.

The utility model has been obtained following technique effect: the utility model effectively raises the efficiency of medicinal rubber circle trimming operation, guarantee cushion rubber trimming quality, trimming precision improves greatly, has promoted product percent of pass, production efficiency, reduction labour intensity simultaneously, has improved product quality.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Fig. 1 is structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, the outer edger of a kind of rubber ring, it comprises lower bolster 2, cope match-plate pattern 7, punch 17, die 19, tapered sleeve 3, main spring 4, guide pillar 8, guide pin bushing 6, punch retainer 15, ladder screw 11, die shank 13, stripper 18, stripper spring 10, upper pin 16 and lower bearing pin 20, in die die cavity, be provided with buffer board 14, between buffer board and lower bolster, be provided with buffer spring 9, between buffer board and lower bolster, connect by screw 14, in the positioning ring groove 1 on buffer board, be provided with retaining ring 12.Between described guide pillars and bushes, be provided with steel ball retainer 5, steel ball retainer is withstood in main spring upper end.

The utility model keeps processed rubber ring 21 profiles indeformable by retaining ring 12, puts into together buffer board 14 positioning ring grooves 1; Carry out trimming action, its sequence of movement is that punch 17 strippers 18 move downward again, and stripper 18 is pushed down glue limit, and punch 17 does trimming action with die 19, and punch 17 and buffer board 14 move downward simultaneously simultaneously, and glue limit is complete the most at last cuts; Open mould and take out processed rubber ring 21.

When processing, first processed medicinal rubber snare is entered to retaining ring and put into buffer board positioning ring groove, then punch and stripper move downward, stripper plays binder effect, punch and die play trimming effect, until cut glue limit, then punch moves upward, stripper plays material returned effect simultaneously, finally takes out retaining ring and processed rubber ring.
