Detailed description of the invention
Core of the present invention is to provide the processing method of a kind of synchronized in conjunction with ring gear, and the method can, in the situation that meeting product design requirement and manufacturing capacity, improve the working (machining) efficiency in conjunction with ring gear, and process be comparatively simple, and tooling cost is lower. Another core of the present invention is to provide a kind of particular manufacturing craft for the above-mentioned synchronous processing method in conjunction with ring gear.
In order to make those skilled in the art person understand better the present invention program, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, Fig. 1 is the flow chart of synchronized provided by the present invention in conjunction with a kind of detailed description of the invention of processing method of ring gear.
A kind of synchronized provided by the present invention is in conjunction with the processing method of ring gear, and in this processing method, synchronized is all processed by Sheet Metal Forming Technology in conjunction with external tooth form, the ring cone flank of tooth and the end face angle of lock of ring gear. Use above-mentioned processing method to manufacture synchronized and only need to use stamping machine and particular manufacturing craft in conjunction with ring gear, equipment investment is less, thereby has solved production cost; Meanwhile, in punching course, without adjusting working process parameter, reduce the error of human intervention, improved production efficiency and Product Precision; Meanwhile, compared with forging, the production process of punching press is comparatively simple, and working (machining) efficiency is higher.
Synchronized provided by the present invention comprises the following steps in conjunction with the processing method of ring gear:
S11 blanking: former material is put into stamping machine and punching press obtains the blank with described external tooth form;
S12 punching press end face angle of lock: punching press obtains described end face angle of lock on described blank;
The S13 punching press ring cone flank of tooth: punching press obtains the described ring cone flank of tooth on described blank.
Like this, first stamp out the end face angle of lock punching press ring cone flank of tooth again, the material producing can avoid punching press end face angle of lock time flows to the ring cone flank of tooth, and the ring cone flank of tooth causing is filled, thereby has further improved production efficiency and Product Precision.
From theory, the processing method of punching press is also not limited to above-mentioned steps, it also can bore the flank of tooth by subpunch pressure ring, backlash pressure side face angle of lock, but, this processing sequence may cause the material producing in the time of processing end face angle of lock to fill the manufactured ring cone flank of tooth, needs the secondary operations of the ring cone flank of tooth.
In above-mentioned steps S11, external tooth form can process by the method for smart punching press, less to ensure the blank end face surface roughness that punching press obtains, and reduces the mismachining tolerance in subsequent handling.
From theory, external tooth form also can be processed by common impact style, in order to ensure its smooth surface, also can carry out the techniques such as polishing.
In above-mentioned steps S12, end face angle of lock can be by the method processing of common punching press, and because the surface roughness of end face angle of lock is less demanding, common punching press can meet its technological requirement, and common cost of stamping is relatively low, has saved production cost.
In above-mentioned steps S13, the ring cone flank of tooth can be by the method processing of common punching press, because the surface roughness of the ring cone flank of tooth is less demanding, common punching press can meet its technological requirement, and common cost of stamping is lower, thereby under the condition that meets technological requirement, save production cost.
Except above-mentioned synchronized is in conjunction with the processing method of ring gear, the present invention also provides a kind of particular manufacturing craft for above-mentioned processing method.
Please refer to Fig. 2 and Fig. 3, Fig. 2 is the structural representation of a kind of detailed description of the invention of the first mould provided by the present invention; Fig. 3 is the structural representation of a kind of detailed description of the invention of the second mould provided by the present invention.
In a kind of detailed description of the invention, particular manufacturing craft provided by the present invention comprises the first mould 1 and the second mould 2, and wherein, the pressing mold portion of the first mould 1 and the shape of end face angle of lock match, and the pressing mold portion of the second mould 2 matches with the shape of the ring cone flank of tooth; Like this, in punching course, blank is put on the first mould 1, under the punching press of stamping machine, because the pressing mold portion of the first mould 1 and the shape of end face lock support match, blank can stamp out end face angle of lock with the position that the pressing mold portion of the first mould 1 contacts; Blank is put on the second mould 2, and under the punching press of stamping machine, because pressing mold portion and the shape of the ring cone flank of tooth of the second mould 2 match, blank wants that with the pressing mold portion of the second mould 2 position contacting can stamp out the ring cone flank of tooth.
Above-mentioned the first mould 1 also comprises guide part, and the outer shape of the blank with external tooth form that guide part obtains with punching press is identical, so that feeding and guiding.
