Problems solved by technology

The shape of the 4032 aluminum alloy bearing seat is complex and difficult to form. The side wall of the traditionally forged face plate is easy to tear, the ribs are not filled enough, the bottom of the plate is seriously folded, the product qualification rate is low, and the overall performance is poor.

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0026] The invention provides a forging method for a machining blank of a bearing seat of a scroll compressor, as shown in the figure, it includes the following steps:

[0027] 1) For descaling, use 4032 aluminum alloy extruded rods with a specification of φ100, and the descaling depth of the outer circle of the turning bar is 1.5-2mm;

[0028] 2) Blanking, sawing machine cutting, according to the post-processing allowance requirements of the product and the principle of constant volume, the thickness of the material is 14-15mm, and the upper and lower deviation is 0.1mm;

[0029] 3) Heat coating 1, heat the tablet to 200±20°C, hang it into the graphite water diluted 20-23 times with tap water and stir it evenly, after staying for 4-6s, stay in the air for 10-15s, put it ...

Abstract

The invention provides a forging method for a scroll compressor bearing seat machining blank. The material is a 4032 aluminum alloy extruded rod with the diameter phi being 100. The technological process comprises the following steps of descaling, discharging, first coating heating, second coating heating, pre-forging, finish forging, heat treatment and shot blasting. The bearing seat machining blank forged through the forging method is good in compactness, simple in process, convenient to operate, high in material utilization rate, high in percent of pass and small in subsequent finish machining allowance. The process is quite suitable for market requirements.

Description

technical field [0001] The invention belongs to the field of metal plastic forming, in particular to a forging method of a machining blank of a bearing seat of a scroll compressor. Background technique [0002] The scroll compressor has the advantages of small size, low noise, long life and reliable operation. Known as the most advanced compressor in the world today. Scroll compressors are widely used in industries such as industry, agriculture, transportation, medical equipment and textiles. The material of the bearing seat is 4032 aluminum alloy, which is an important accessory in the scroll compressor. The temperature difference in the working environment is large, so it not only has to bear the alternating stress caused by the high-speed rotation of the crankshaft, but also bears a certain impact load. The quality of the bearing seat plays an important role in ensuring the normal operation, working stability and service life of the compressor. The shape of the 4032 al...
