Embodiment Construction
[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0023] refer to figure 1 As shown, a stator processing method is characterized in that:
[0024] Step 1. Incoming material inspection, check whether each component meets the requirements according to the product material requirements;
[0025] Step 2, blanking, blanking Φ60×32 according to the required size on the special blanking machine;
[0026] Step 3, hot forging, forging and forming on hot forging equipment to ensure the compactness of the material, and remove excessive allowance for machining, with a thickness of 27min;
[0027] Step 4, T6 treatment, to ensure that the material properties conform to the drawing non-proportional elongation strength ≥ 245MPa, tensile strength ≥ 265MPa, elongation after fracture ≥ 9%;
[0028] Step 5. Rough drilling is processed on a drilling machine, and the middle hole of the outer circle is...

Abstract
The invention discloses a processing method of a stator, which comprises the following steps of: feeding and checking: checking whether various components meet the requirement or not according to the requirement on a material of a product; blanking: blanking in a special blanking machine according to the required size; hot forging: forging and forming on hot forging equipment; carrying out T6 treatment to ensure that properties of the material meet the requirement of a drawing; roughly drilling, clamping an excircle and roughly drilling an intermediate hole; turning a surface A, boring an intermediate hole and positioning the datum for subsequent processing; turning a back side and the excircle and positioning the datum for subsequent processing; broaching a groove and positioning according to the end surface of a concave surface; drilling and milling an inner cavity of the surface A, positioning according to the groove and a bottom surface, pressing an upper end surface and processing the diameter of the inner cavity; stabilizing the positioning datum so as to extremely-easily ensure the position degree; turning two surfaces, internally expanding a section cavity and turning a front side and a back side in one step; oxidizing an anode and treating an oxidation layer in special oxidation equipment; inspecting a finished product; and packaging and warehousing. According to the processing method disclosed by the invention, the processing datum is enabled to be stabilized; the processing capability and the efficiency are improved; the processing quality is ensured; the subsequent feeding yield is greatly improved; and the production cost is reduced simultaneously.
Description
technical field [0001] The invention relates to the machining of the intake stator of the variable phaser system of the engine. Background technique [0002] This part belongs to the variable phaser system of BAIC engine. The conventional processing method is incoming inspection-cutting-rough drilling-turning A surface and boring center hole-turning back and outer circle-drilling and milling A surface-grooving-milling A Face-milling back-anodizing-inspection and shipment; this method is difficult to guarantee the position when drilling and milling the A surface, and it is not easy to process the parallelism of the two sides. Contents of the invention [0003] The object of the invention is to provide a processing method with stable processing standards, high efficiency, high quality and low cost. [0004] In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the present invention is realized through the following techn...
