Description
Technical field
The invention belongs to chain manufacturing technology field, more particularly to a kind of chain, sharp_fanged link joint and its carrier bar automatic press
Moulding process.
Background technology
All the time, sharp_fanged link joint is the important composition part in sharp-tooth chain, and the profile of sharp_fanged link joint is by circular arc and straight
Line is constituted, and has two holes on carrier bar, and with bearing pin or sleeve interference fit, an important feature feature of sharp_fanged link joint is Kong Xinlian
There is a pointed tooth in the Symmetrical vertical direction of line, the wedge angle of pointed tooth within 20 °, and tines portion account for whole Link plate height 40～
60%, flattened portion accounts for 50% of pointed tooth or so, and the thickness of minimum (thin) part is thick 0.1～0.2 of material, must not there is angle of collapsing.
Traditional sharp_fanged link joint stamping procedure adopts following steps：Punching（Including punching, blanking）→ correction of the flank shape → quenching →
Sharpening tooth.Need multiple devices to carry out corresponding operation successively, two endoporus and tooth are made by simple stamping first on punch press
The exterior contours such as point, now the pointed tooth portion fillet of carrier bar is very big, then carries out retapering angle with another punch press and mould（Use carrier bar
Holes is positioned）, then the heat treatment process of carrier bar is carried out, with gradient frock grinding carrier bar on surface grinding machine after heat treatment
Pointed tooth portion, the defect that as known from the above existing processing technology is present has：
1）Punch extermal form and deburring, if one-shot forming, are not only produced tight with different mould and punch press at sharp_fanged link joint pointed tooth
The punching quality problems such as angle of collapsing, the shearing facial disfigurement of weight, and the stress concentration of mould is larger, and the drift and die of mould are easily
Damage, therefore using thick punch extermal form mould and fine profile mould, and with two punch presses.
2）Carrier bar pointed tooth needs artificial roll flute, and due to equipment precision problem, grinding size is difficult to ensure, and artificial per tour
Production efficiency be less than 5000.
3）Due to being single process, each operation is both needed to positioning, causes carrier bar precision low, is also easy to produce 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 more, and occupancy equipment is more, and required artificial many, complex operation, energy consumption are big, production efficiency
It is low.
6）Individual product repairing form produces pointed tooth portion's fragmentation and deformation, causes carrier bar to be scrapped.
The content of the invention
In order to solve above-mentioned technical problem, it is integrated automatically that an object of the present invention is to provide a kind of chain sharp_fanged link joint
Punch forming process, few so as to realize processing equipment needed thereby, operation is few, and machining accuracy is high, improves the high purpose of product percent of pass.
