Description
Technical field
The invention belongs to chain manufacturing technology field, particularly relate to a kind of chain, sharp_fanged link joint and carrier bar automatic press moulding process thereof.
Background technology
All the time, sharp_fanged link joint is the important composition part in sharp-tooth chain, the profile of sharp_fanged link joint is by circular arc and rectilinear(-al), carrier bar there are two holes, with bearing pin or sleeve interference fit, an important feature feature of sharp_fanged link joint is that the Symmetrical vertical direction of hole heart line has a pointed tooth, the wedge angle of pointed tooth is within 20 °, and tines portion accounts for 40 ~ 60% of whole Link plate height, flattened portion accounts for about 50% of pointed tooth, and thickness of minimum (thin) part is material thick 0.1 ~ 0.2, must not have angle of collapsing.
Traditional sharp_fanged link joint stamping procedure adopts following steps: punching (comprising punching, blanking) → correction of the flank shape → quenching → sharpening tooth.Namely multiple devices are needed to carry out corresponding operation successively, first on punch press, the exterior contours such as two endoporus and crown are made by simple stamping, now the pointed tooth portion fillet of carrier bar is very large, then retapering angle (with carrier bar holes location) is carried out with another punch press and mould, carry out the heat treatment process of carrier bar again, the pointed tooth portion of the frock grinding carrier bar using band gradient after heat treatment on surface grinding machine, the defect that existing processing technology exists as known from the above has:
1) punch extermal form and deburring different moulds and punch press, if one-shot forming, not only sharp_fanged link joint pointed tooth place produces the serious stamping-out quality problems such as angle of collapsing, shear surface distortion, and the stress of mould is concentrated larger, drift and the die of mould very easily damage, therefore thick punch extermal form mould and smart punch extermal form mould is adopted, and with two punch presses.
2) carrier bar pointed tooth needs artificial roll flute, and due to equipment precision problem, grinding size not easily ensures, and the production efficiency of artificial per tour is no more than 5000.
3) owing to being single process, each operation all needs location, causes carrier bar precision low, easily produces waste product.
4) deburring, grinding process are artificial feeding and discharging, and processing safety is poor, and efficiency is low.
5) whole process operation is many, takies equipment many, and required artificial many, complicated operation, energy consumption are large, production efficiency is low.
6) individual product cracked and distortion in correction of the flank shape formula generation pointed tooth portion, causes carrier bar to be scrapped.
Summary of the invention
In order to solve above-mentioned technical problem, an object of the present invention is to provide the integrated automatic press moulding process of a kind of chain sharp_fanged link joint, thus it is few to realize processing equipment needed thereby, and operation is few, and machining accuracy is high, improves the object that product percent of pass is high.
Two of object of the present invention is to provide a kind of carrier bar, adopts above-mentioned punch forming process to obtain.
Three of object of the present invention is to provide a kind of chain, has above-mentioned carrier bar.
In order to realize above-mentioned object, present invention employs following technical scheme:
The integrated automatic press moulding process of a kind of chain sharp_fanged link joint, it is characterized in that: adopt multi-position continuous punching die tool to carry out progressive stamping formed machining to steel band, described multi-position continuous punching die tool is disposed with along the grading throughput direction of steel band: punching station, trimming station, just flatten station, the flat station of pressure-sizing, deburring station, smart punching station and blanking station; Wherein,
