Abstract
The invention discloses a modified blanking die of a bicycle chain guard connecting piece. The modified blanking die of the bicycle chain guard connecting piece comprises a die body and a die knife edge, wherein the die knife edge is arranged in the middle of the die body, the die knife edge comprises a first omega-shaped chain guard connecting piece knife edge and a second omega-shaped chain guard connecting piece knife edge, and a pin of the first omega-shaped chain guard connecting piece knife edge is arranged in an inner round arc of the second omega-shaped chain guard connecting piece knife edge. In this way, the modified blanking die of the bicycle chain guard connecting piece can improve work efficiency and lower the production cost.
Description
Technical field
The present invention relates to bicycle manufacturing technology field, particularly relate to the blanking die of a kind of Modified type bicycle chain guard contact pin.
Background technology
In prior art, the chain guard tab construction formula being used on bicycle is an open circles arcuate structure, adopting diel to add man-hour, it is generally single blanking, thereby assurance product quality, but working (machining) efficiency is low, wherein after the circular arc material punching press of chain guard contact pin inner ring, substantially does waste disposal, so raw material availability is low, also increased product cost simultaneously.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the blanking die of a kind of Modified type bicycle chain guard contact pin, can increase work efficiency, and reduces production costs.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the blanking die that the contact pin of a kind of Modified type bicycle chain guard is provided, comprise: die ontology and the mould edge of a knife, the described mould edge of a knife is arranged on the middle part of die ontology, the described mould edge of a knife comprises first " Ω " type chain guard contact pin edge of a knife and second " Ω " type chain guard contact pin edge of a knife, and a pin of described first " Ω " type chain guard contact pin edge of a knife is placed in the interior circular arc of second " Ω " type chain guard contact pin edge of a knife.
In a preferred embodiment of the present invention, described die ontology comprises upper die and lower die, and the described mould edge of a knife is separately positioned on the middle part of patrix and the middle part of counterdie.
The invention has the beneficial effects as follows: 2 chain guard contact pin of blanking of blanking die of Modified type bicycle chain guard of the present invention contact pin, have improved operating efficiency and availability ratio of the armor plate.
Accompanying drawing explanation
Fig. 1 is the edge of a knife distributed architecture schematic diagram of the blanking die of Modified type bicycle chain guard of the present invention contact pin;
Fig. 2 is the structural representation of the blanking die of Modified type bicycle chain guard of the present invention contact pin;
In accompanying drawing, the mark of each parts is as follows: 1, die ontology; 2, the mould edge of a knife; 10, patrix; 11, counterdie; 20, first " Ω " type chain guard contact pin edge of a knife; 21, second " Ω " type chain guard contact pin edge of a knife; 200, pin; 210, interior circular arc.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises: the blanking die of a kind of Modified type bicycle chain guard contact pin, comprise: die ontology 1 and the mould edge of a knife 2, the mould edge of a knife 2 is arranged on the middle part of die ontology 1, the mould edge of a knife 2 comprises that a pin 200 of first " Ω " type chain guard contact pin edge of a knife 20 and second " Ω " type chain guard contact pin edge of a knife 21, the first " Ω " type chain guard contact pin edge of a knife 20 is placed in the interior circular arc 210 of second " Ω " type chain guard contact pin edge of a knife 21.
Furtherly, described die ontology 1 comprises patrix 10 and counterdie 11, and the mould edge of a knife 2 is separately positioned on the middle part of patrix 10 and the middle part of counterdie 11.
The blanking die of Modified type bicycle chain guard of the present invention contact pin in the course of the work, raw material are cut into than larger a little the material strip of the width of chain guard contact pin, or be directly customized to the coiled tape of certain width, material strip is placed between patrix 10 and counterdie 11 and to material strip and is located, wherein 2 pairs of material strips of the mould edge of a knife are sheared punching press, the efficiency operation mode that completes two product outputs of a punching press, on material strip, remaining waste material is also few, has saved cost of material.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
Claims (2)
