Description

Automatic production line for static vortex disc Technical Field The invention relates to the technical field of manufacturing of automobile parts, in particular to an automatic production line for manufacturing a new energy oil-free air conditioner compressor static vortex disc. Background Forging is a processing method for forging a metal blank by applying pressure to the metal blank by using forging machinery to plastically deform the metal blank so as to obtain a forging piece with certain mechanical properties, shape and size. Forging can eliminate as-cast loose and welded holes of metal, so that its mechanical property is superior to that of casting of identical material, so that some important parts with high load and severe working condition in the machine are made up by adopting forging and pressing process. For example, a compression part of an oil-free air conditioner compressor for new energy vehicles in the automobile industry, namely a static vortex disc, is mostly manufactured by forging and pressing. The static vortex disc forging and pressing process is that a flat rough blank piece is placed into an upper cavity of a fixed mold core of a mold, forging and pressing equipment drives an upper mold mechanism and a pressing head to press downwards, and the lower part of the rough blank piece is plastically extruded into a volute lower cavity to form a volute of a forging piece. The forging die and the forging process of the fixed scroll belong to the mature prior art. The forging and pressing process is only one ring of the whole production line, the rough blank before forging and pressing is further subjected to a series of preceding processes such as preheating by an intermediate frequency furnace, soaking graphite, secondary heating by a mesh belt furnace and the like, and the forged and pressed forging piece is further subjected to subsequent processes such as flanging by machining, shot blasting and the like. Specifically, the worker manually places the rough blank into the inlet of the intermediate frequency furnace, pushes the rough blank into the intermediate frequency furnace along a first channel by a first pushing cylinder to preheat the rough blank to about 250 ℃, and then discharges the rough blank from the outlet. And then the preheated rough blank is clamped by a hand-held pliers of a worker and soaked in the graphite tank. And then, the rough blank piece clamped by a worker through the pliers after the secondary heating is sent to an upper cavity of a forging die for forging. During forging, the upper die mechanism presses down the rough blank in the upper die cavity of the fixed die core to enable the rough blank to be plastically deformed downwards to form a vortex body, the upper edge of the rough blank is synchronously and reversely extruded into a gap between the pressing head and the upper die cavity upwards to form an upward flanging, and therefore the flanging of the forged piece is required to be removed. The existing method is that a worker takes out a high-temperature forging piece from a die after die opening by using pliers, places the high-temperature forging piece on the ground to cool the high-temperature forging piece, and then manually turns off a flanging by using a numerical control machine tool. And finally, performing shot blasting and sand blasting on the cut workpiece to obtain a fixed vortex disc finished product. The above-described prior art fixed scroll production line and process have the following drawbacks. 1. The flanging procedure is carried out by manually clamping the high-temperature forging piece from the die, the clamping operation is complicated and laborious, the hidden danger of scalding exists, the high-temperature forging piece cannot be directly turned, the ground is required to be placed for full cooling, the continuity of production is broken, the time is long, the speed is low, the efficiency is low, the yield is restricted, the turning procedure is manually operated, the labor is wasted, the cutting consistency is poor, errors are easy, and the yield is insufficient. 2. During forging, graphite is soaked on the surface of a rough blank for heat insulation and temperature reduction, and the graphite is adhered to the surface of a forged piece, so that the color is blackish, the burden of a subsequent shot blasting and sand blasting process can be increased, a large number of sand shots are consumed, and the color of finished products on the rear side of the shot blasting is dark and non-uniform. 3. The mesh belt furnace is used as secondary heating, namely reheating equipment, has low automation degree, is labor-operated, consumes labor, increases labor cost, clamps high-temperature reheating workpieces, is complex and dangerous in operation, is highly dependent on worker experience, has poor consistency of time and rhythm of soaking and reheating feeding, is easy to influence soaking and reheating effects, and further, graphite is
