Embodiment Construction
[0016] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0017] Such as image 3 with Figure 4 As shown, the present invention uses a low-carbon steel sheet with a suitable thickness as the base material of the valve plate. First, the shape of the valve plate, the mounting holes around the valve plate, the positioning holes, and the inlet valve holes on the valve plate are processed by precision stamping. And the annular groove around the opening of one end of the intake valve hole and the installation groove of the suction valve tongue connected with the annular groove, forming an annular protrusion at the same time between the intake valve hole opening and the surrounding annular groove At the same time, the top surface of the ring-shaped protrusion is also formed; then, the valve plate is turned over, and the exhaust valve hole on the valve plate and the annular groove around the one end of the...

A compressor valve plate manufacture method belongs to the refrigeration system compressor field; an existing compressor valve plate is made by powder metallurgy with large energy consumption, polluted environment and long manufacture period; the method comprises the following steps: firstly employing mild steel sheet material with proper thickness as valve plate base material; using precision stamping technology to process the valve plate profile, valve plate surrounding mount holes and positioning holes, a valve plate air inlet valve hole, an annular groove surrounding one end orifices of the air inlet valve hole, a valve plate air outlet valve hole, and an annular groove surrounding one end orifices of the air outlet valve hole. When the annular groove is stamped and processed, an annular protrusion can be simultaneously formed between the air inlet valve hole and the surrounding annular groove, and an annular protrusion can be simultaneously formed between the air outlet valve hole and the surrounding annular groove; the whole end faces on two ends of the valve plate can be grinded by a grinding machine. The compressor valve plate manufacture method can greatly reduce the valve plate manufacture period, can reduce production cost, is small in energy consumption, cannot cause environment pollution, thus complying with green manufacture development prospects.
Description
technical field [0001] The invention belongs to the field of refrigeration system compressors, and in particular relates to a method for manufacturing a valve plate for a compressor. Background technique [0002] The air valve is an important part of the compressor in the refrigeration system. The air valve generally includes a valve plate and two valve pieces covered on the entire end surface of the two ends of the valve plate. The valve plate and the two valve pieces are respectively provided with mounting holes and positioning holes around them. , the middle part of the valve plate is provided with an intake valve hole and an exhaust valve hole, the two valve plates are respectively provided with an intake valve tongue and an exhaust valve tongue, and the intake valve tongue and the exhaust valve tongue are respectively sealed on the inlet Air valve hole and exhaust valve hole. Such as figure 1 with figure 2 As shown, the valve plate end face 1 where one end of the in...
