Description
Technical field
The present invention relates to a kind of processing technology, and in particular to a kind of processing technology of belt pulley, belongs to cold punching technology neck
Domain.
Background technology
Belt pulley is a kind of important mechanical transmission part, and it is widely used in the various of automobile, agricultural machinery and light and textile industries
In machine driving.The conventional fabrication processes of belt pulley are that blank is made using casting technique, then it is machined be made, tradition system
The shortcoming for making technique is that serious waste material, low production efficiency, Product Precision are low, and the belt pulley produced is low because of precision, need to enter
Row Balance Treatment.
The content of the invention
It is an object of the invention to overcome the shortcoming of traditional handicraft and realize lightweight, so as to provide a kind of new processing work
Skill, ensure that the precision of belt pulley, improve stock utilization, and production efficiency is high, and product quality is light, and balance is good, without flat
Weighing apparatus processing.
Technique according to the invention scheme, the processing technology of the belt pulley, comprises the following steps：
（1）Blanking：By roller flatteningl roller levelling and diameter needed for striking out and thickness circular blank；
（2）Pre-punched hole：To step（1）Circular embryo material center carry out pre-punched hole；
（3）The first step is stretched：By step（2）It is drawn into the middle part of middle embryo material to side bowl-shape；
（4）Second step is stretched：By step（3）In the side wall of bowl-shape embryo material further stretch, make it perpendicular to bottom surface；
（5）Integer：Fillet outside stretched portion is shaped to right angle, inner bottom surface fillet shaping bevel；
（6）Trimming：Redundance excision in embryo material outward flange is reached into required size；
（7）Flange：By step（6）Embryo material outward flange through trimming is to step（2）Middle draw direction translates into vertical straight flange；
（8）Whole R angles：By step（7）Middle flange radius integer size needed for；
（9）Enlarging：Part on flange is forced radially to expand using mould；
（10）Bulging：Ensure that flange is central raised, shrink flanging upper shed；
（11）Punching：To step（2）In pre-punched hole be outwards further punched circular waste material, the hole of diameter needed for obtaining.
Further, the processing technology of the belt pulley is cold punching technology.
Further, the step（7）In, the height of flange is higher than step（2）The height of middle stretching.
Further, the step（8）In, the height of flange is slightly above step（2）Middle stretched portion internal depth.
Further, the step（10）In, flange upper shed is consistent with diameter at flange.
The present invention has advantages below compared with prior art：The precision of belt pulley is ensure that, stock utilization is improved,
Production efficiency is high, and product quality is light, and balance is good, without Balance Treatment.

Embodiment
With reference to specific accompanying drawing, the invention will be further described.
As shown in Figure 1 and Figure 2：The processing technology of the belt pulley comprises the following steps：
（1）Blanking 1：By roller flatteningl roller levelling and diameter needed for striking out and thickness circular blank；
（2）Pre-punched hole 2：To step（1）Circular embryo material center carry out pre-punched hole；
（3）First step stretching 3：By step（2）It is drawn into the middle part of middle embryo material to side bowl-shape；
（4）Second step stretching 4：By step（3）In the side wall of bowl-shape embryo material further stretch, make it perpendicular to bottom surface；
（5）Integer 5：Fillet outside stretched portion is shaped to right angle, inner bottom surface fillet shaping bevel；
（6）Trimming 6：Redundance excision in embryo material outward flange is reached into required size；
（7）Flange 7：By step（6）Embryo material outward flange through trimming is to step（2）Middle draw direction translates into vertical straight flange；
（8）Whole R angles（I.e.：Full circle arc angle）8：By step（7）Middle flange radius integer size needed for；
（9）Enlarging 9：Part on flange is forced radially to expand using mould；
（10）Bulging 10：Ensure flange mid diameter, shrink flanging upper shed；
（11）Punching 11：To step（2）Middle pre-punched hole is outwards further punched circular waste material, the hole of diameter needed for obtaining.
Specifically, the processing technology of inventive belt wheel is cold punching technology；Step（7）In, the height of flange is higher than step
Suddenly（2）The height of middle stretching, facilitates the processing of whole R angles 8 and the grade of enlarging 9 to flange；Step（8）In, the height of flange is slightly above
Step（2）Middle stretched portion internal depth；Step（10）In, flange upper shed is consistent with diameter at flange.
Processing technology of the present invention uses enlarging 9, the process of bulging 10, and material is by two-way action of pulling stress, in the absence of compression,
And tension through-thickness is evenly distributed, therefore Instability wrinkling is difficult, resilience is small, surface quality is good, it is ensured that belt pulley
Precision, improve stock utilization, production efficiency is high, product quality is light, and balance is good, without Balance Treatment.
