Abstract
The present invention relates to process of forming casing for air conditioner compressor, and belongs to the field of machining technology. The process includes the steps of longitudinal shearing coiled plate, winding and welding to form high frequency welded steel pipe, cutting to required length, cleaning, pickling, expanding inner diameter, chamfering, shaping, making bottom cover, boxing and inspection. The present invention makes air conditioner compressor casing with high frequency steel pipe, and has high material utilizing rate, high product precision, capacity of lowering noise of the compressor and other advantages.
Description
Technical field
The present invention relates to a kind of air-conditioner compressor outer housing (cylindrical shell) moulding process, belong to the Machining Technology field.
Background technology
Air-conditioner compressor outer housing is mainly used in the parts of the compressor that installs an air-conditioner in the housing, and forms enclosed cavity, stores compressor medium and lubricating fluid etc., and is convenient to test, transportation etc.In prior art, be used to process air-conditioner compressor outer housing and normally adopt deep drawn, cold-drawn processing, turning processing technology, adopt deep stretching process the most general.The deep stretching process procedure of processing is as follows: material selection ST13, ST14 (acid-cleaning plate).Earlier with the pickling flat board side of being cut into plate, blanking becomes disk then, again through one draw, two draw, shaping, three is drawn, shaping, four is drawn, shaping, side cut, chamfering, punching, is finished product at last.Adopt above-mentioned processing technology stock utilization low, loss is big; Die needed many, percent defective height, processing charges height; Internal diameter of outer cover poor (because pull and stretch stress and wall thickness attenuation cause); Compressor noise big (because stretching wall thickness); The product that same inner diameter length is different only need be opened different blanking dies, stretching die; Shell bottom and shell body fuse, and can't dismantle when compressor is tested, and can not satisfy the client and assemble needs.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of technique of forming air conditioning compressor casing is provided, its stock utilization height increases yield rate, and loss is little; Product internal diameter precision height, circularity are good, can reduce compressor noise; The product that same inner diameter length is different only needs to adjust Pipe Cutting length location, and processing technology is simple.
Main solution of the present invention is achieved in that
Technique of forming air conditioning compressor casing of the present invention adopts following processing step:
1, roll bending slitting rolls through being welded into the ratio-frequency welding steel pipe; 2, be cut into required steel pipe by length; 3, steel pipe is carried out cleaning treatment; 4, steel pipe is carried out pickling processes; 5, internal diameter of outer cover expander; 6, flat head chamfering; 5, punching; 6, shaping; 7, make bottom, and carry out boxing; 8, verify as finished product.
Described pipe diameter is: φ 80mm-φ 250mm, and steel pipe length is: 5m-8m, thickness of steel pipe is: 2.0mm-7.5mm; Described internal diameter of outer cover precision is: ± 0.05mm; Circularity is in the shell: 0.2mm.
Compared with the prior art the present invention has the following advantages:
The compressor case that the present invention adopts the high frequency steel pipe to make, its stock utilization height, loss is little; Product internal diameter precision height, circularity good (the little wall thickness of stress is even), and can reduce compressor noise, increase yield rate; The product that same inner diameter length is different only needs to adjust Pipe Cutting length location, and processing technology is simple; Shell bottom and shell body can be for convenience detach, help the client and assemble needs.

6, punching: the punching precision be (+0.1mm+0.2mm); The hole is used to connect compressor air inlet-outlet pipe and cylinder body etc.;
7, shaping; Adopt special-purpose expander equipment and mold to carry out shaping.
8, make bottom, and carry out boxing.(can not welding bottom, convenient user assembled needs) according to customer requirements yet
9, verify as finished product.
On shell (cylindrical shell), support and copper pipe etc. are set at last, easy to use.Processing technology of the present invention is simple, its stock utilization height, and loss is little; Product internal diameter precision height, circularity good (the little wall thickness of stress is even), and can reduce compressor noise, increase yield rate.
Embodiment two
The roll bending slitting rolls through being welded into the ratio-frequency welding steel pipe; Pipe diameter is: Φ 100.91mm, steel pipe length is: 6m, thickness of steel pipe is: 2.6mm.The air-conditioner compressor outer housing (cylindrical shell) that adopts the production and processing technology among the embodiment one to make can satisfy user's assembling demand, and its stock utilization height can increase yield rate, and spillage of material is little; Product internal diameter precision height, circularity are good, and can reduce compressor noise.
Embodiment three:
