Problems solved by technology

The existing cavity is usually made of ordinary galvanized sheet or stainless steel sheet. Because ordinary galvanized sheet or stainless steel sheet is easily oxidized and discolored by heat at high temperature, it is difficult to clean, and the heat reflection effect becomes poor, which affects the user experience.

Embodiment 1

[0048] Such as figure 1 As shown, a kind of electroplating cavity comprises a cavity blank and an electroplating layer coated on the cavity blank. The cavity blank includes a front plate, a rear plate, a U plate, and a bottom plate. In the electroplating layer Each component includes: 70%-90% copper; 10%-20% nickel; 0.5%-5% chromium, more preferably 75%-85% copper; 13%-16% nickel; 2% chromium ~3%.

[0049] Furthermore, it can also be considered in the present invention that the thickness of the electroplating layer is 12-15 μm, more preferably 12-13.5 μm.

Embodiment 2

[0051] A method for manufacturing an electroplating cavity. First, the appearance of the cavity blank is inspected, and the cavity blank that passes the inspection is hung on a hanger; the manufacturing method also includes the following steps:

[0052] Step 1: pre-plating treatment: the pre-plating treatment acts on the surface of the cavity blank to remove the grease layer, wax layer and rust film on the surface of the cavity blank, and improve the bonding force between the electroplating layer and the cavity blank, To increase the efficiency of electroplating.

[0053] Include the following steps:

[0054] A. Place the cavity blank in the degreasing tank for thermal degreasing;

[0055] B. Place the cavity blank processed in the above steps in a washing tank for washing;

[0056] C. Place the cavity blank processed in the above steps in the wax removal tank for ultrasonic wax removal

[0057] D. Place the cavity blank processed in the above steps in a washing tank for wash...

Embodiment 3

[0094] Abrasion test of stainless steel bottom plate

[0095] 1. Test purpose: To investigate the electroplated nickel-chromium layer on the stainless steel bottom plate (the components in the electroplated nickel-chromium layer include: copper 70% to 90%; nickel 10% to 20%; chromium 0.5% to 5%, with a thickness of 12 -15μm) wear resistance.

[0096] 2. Test conditions:

[0097] a. Test product placement: consistent with the actual use conditions

[0098] b. Test environment: Verify on the TOKIT oven, assemble an electroplated stainless steel bottom plate and an unplated stainless steel bottom plate for a comparative test.

[0099] 3. Test method:

[0100]a. Before the aging test of the prototype, check the stainless steel bottom plate. Both the electroplated stainless steel bottom plate and the unplated stainless steel bottom plate are intact without scratches.

[0101] b. Use a scouring pad to wipe back and forth 20cm on the base plate as one cycle, and perform a total o...

Abstract

The invention relates to an electroplating cavity. The electroplating cavity comprises cavity blank and an electroplating layer coated on the cavity blank, wherein the electroplating layer consists ofthe following components in percentage by weight: 70%-90% of copper, 10%-20% of nickel, and 0.5%-5% of chromium. The invention further relates to a manufacturing method for the electroplating cavity,and the manufacturing method comprises the following steps: performing pre-plating treatment, plating nickel for bottoming, plating shinning copper for bottoming, plating acid copper for bottoming, plating shinning nickel, performing nickel sealing, plating chromium, dehydrating, roasting and packaging. The invention provides the electroplating cavity which does not change color after high-temperature roasting, strengthens corrosion resistance, friction resistance, glossiness and thermal reflection performance, and a manufacturing method thereof.

Description

technical field [0001] The invention belongs to the technical field of ovens, and in particular relates to an electroplating cavity and a manufacturing method. Background technique [0002] The electric oven uses a heating tube to generate heat to increase the temperature of the oven cavity, so as to achieve the purpose of heating food. During the cooking process, the cavity is in a state of high-temperature grilling for a long time. The existing cavity is usually made of ordinary galvanized sheet or stainless steel sheet. Because ordinary galvanized sheet or stainless steel sheet is easily oxidized and discolored by heat at high temperature, it is difficult to clean and the heat reflection effect becomes poor, which affects the user experience. [0003] Therefore, based on these problems, it is of great practical significance to provide an electroplating cavity and a manufacturing method thereof that do not change color after high-temperature baking, and have enhanced corr...
