Description
Technical field
The present invention relates to automobile manufacturing field, specifically the processing technology of a kind of spark-plug body。
Background technology
Along with automobile, the development of motorcycle industry, as the element of engine ignitor, spark plug is also developed rapidly accordingly。Spark plug is consumable accessory, and consumption is big, and standardization level is also high, studying the manufacturing process of this part, have huge economic potential, spark plug iron-clad manufacturing process is now few from being changed into by hexagonal steel machining, without cutting technology, namely rod extrusion technology combines with Cutting Process。So cold extruding technique is a kind of a kind of processing technique meeting modern crafts production。
Summary of the invention
It is an object of the invention to provide the processing technology of a kind of spark-plug body。
For realizing such purpose, the technical scheme is that the present invention adopts cold-stamped method to carry out the making of spark-plug body, decrease the cutting head cutting tail of centre, drastically increase yield rate。The concrete technology step of the present invention is as follows:
1) material choice, technique of the present invention is to produce spark-plug body with cold extruding technique, so adopting phosphorus content relatively low, and the resistance of deformation after annealing, No. 15 steel that flow harden sensitivity and cost are all relatively low, and adopt blanking preforming multistation extrusion forming technology；
2) blanking, shaping, choose required No. 15 steel and first carry out outside shaping on cold headers；
3) annealing, in step 2) complete after material is carried out full annealing, reduce its hardness, improve its plasticity, at the turnery processing that cold-extrusion shaping rear continues after an action of the bowels；
4) acidifying, phosphatization, carry out acidification before phosphatization, then workpiece intrusion Phosphating Solution carries out bonderizing；
5) one squeeze, two squeeze, three squeeze, by three times extruding from mould extrude spark-plug body；
6) punching the wad, the residue material in finisher's station；
7) machining, repairs the blank of extrusion, processes, carries out smooth surface, and seamed edge processes。
The processing technology of described a kind of spark-plug body, it is characterized in that, described processing step 4) in souring operation be: workpiece is invaded at 50 DEG C-60 DEG C, etch 5min-10min in the sulfuric acid solution (added with buffer agent) of 5%-10%, washing, then it is used in etch 0.5min-2min in the sulfuric acid solution (added with buffer agent) that concentration is 1%-5%。
The processing technology of described a kind of spark-plug body, it is characterised in that described processing step 4) in workpiece carried out the technique of phosphatization be: workpiece is invaded the Phosphating Solution 7min-15min that temperature is 50 DEG C-70 DEG C。
The beneficial outcomes of the present invention:
Can greatly improve the mechanical property of materials, improve stock utilization, raise labour productivity, remarkable in economical benefits, the performance improving spark plug there is is great benefit simultaneously。
