Embodiment 1

[0036] Such as figure 2 As shown, the aluminum alloy handle of the refrigerator door is prepared by the process of the present invention, and the aluminum alloy model is 6063.

[0037] S1: Preparation of the refrigerator door frame handle blank. According to the product size requirements of the handle, the handle rough blank is produced by extrusion molding process. The handle rough blank is sequentially processed by sawing, stamping and CNC machine tool to obtain the refrigerator door frame handle blank;

[0038] S2: Refining the surface of the refrigerator door frame handle blank. The surface of the refrigerator door frame handle blank produced in step S1 is subjected to a chamfering treatment, wire drawing treatment, polishing treatment and a second chamfering treatment in sequence to obtain a refrigerator door frame handle initial product, wherein the wire drawing treatment The used grinding wheel is connected to the grinding wheel driving stepping motor, and the grinding...

Embodiment 2

[0042] The difference between embodiment 2 and embodiment 1 is that in the step S2 wire drawing process, the peripheral surface of the grinding wheel is alternately provided with end-to-end arc-shaped areas of 200 mesh, 250 mesh and 300 mesh, and the rotation speed of the grinding wheel is 2400r / min The model of sandpaper used in the step S2 grinding process is 400 orders; the step S3 sand blasting process uses steel grit as the spray material, and the model of the steel grit is 150 orders, and the pressure of the sand blasting process is 3.5kg / cm 2 The primary oxidation treatment in step S3 is to put the refrigerator door frame handle into the anodizing tank, the anode voltage is 14V, the oxidation time is 40min, the solution concentration in the anodizing tank is a sulfuric acid solution of 220g / L, and the oxidation temperature is 20°C The step S3 secondary oxidation treatment is to put the refrigerator door frame handle into the anodizing tank, the anode voltage is 11V, th...

Embodiment 1～2 and comparative example 1～6

[0055] Embodiment 1~2 and comparative example 1~6 experimental data

[0056]

[0057] Experimental results show that: the outer surface of the aluminum alloy handle of the refrigerator door frame prepared by the process of the present invention in Examples 1-2 has no visible flaws, excellent gloss, excellent texture clarity, a first-time good product rate of more than 95%, and a product scrap rate of 2% or less; the aluminum alloy handles of the refrigerator door frames produced in Comparative Examples 1-2 did not adopt the drawing process, and the outer surface of the aluminum alloy handles of the refrigerator door frames produced had defects visible to the naked eye, and the gloss and texture clarity were better than those in Examples 1-2 Poor, the first-time product yield is about 75%, and the product scrap rate is over 7%; the outer surface of the aluminum alloy handle of the refrigerator door frame produced in Comparative Examples 3 to 6 has no visible flaws with the na...

Abstract

The invention discloses a production process and production equipment of a refrigerator door frame handle. The production process comprises the following three steps of preparing a refrigerator door frame handle blank; finish machining the refrigerator door frame handle blank surface and maintaining the refrigerator door frame handle blank surface. The production equipment comprises a bottom plate, an inverted-U-shaped support, a grinding wheel driving stepping motor, a connecting shaft driving stepping motor, a connecting shaft, a grinding wheel and a controller are arranged on the bottom plate. The production process is simple and convenient to operate, the appearance effect of the refrigerator door frame handle produced by the process is better and fine, the one-time yield during the production of the handle is improved, and the rejection rate of the product is reduced; the production equipment is simple in structure and convenient for industrial application implementation of the process.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a production process and production equipment of a door frame handle of a refrigerator. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industrial production, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for aluminum alloy structural parts is increasing day by day. Aluminum alloy has low density, but relatively high strength, which is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel. . [0003] With the improvement of people's living standards, people are ...
