Problems solved by technology

[0004] At present, the treatment method of the aluminum wire reel terminal is: first remove the aluminum enamelled paint, then soak the flux, then cold press, and finally tin, the use of flux has a strong corrosion effect on the enameled wire paint, use a section on the aluminum wire reel After a period of time, the paint skin of the aluminum wire near the terminal is corroded, causing an open circuit and affecting the service life of the wire reel

Embodiment 1

[0018] figure 1 As shown, insert the end of the lead wire 3 of the aluminum enameled wire reel 1 into the terminal 2, place it in the cold pressing equipment, and use 6 kg of pressure to flatten the terminal 2 and the end of the lead 3 inserted into the terminal 2 together. , so that the terminal 2 and the end of the lead wire 3 are fixedly connected; then place it in a hot pressing device, and use a pressure of 6 kg and a temperature of 600°C for 4 seconds to heat the same part of the cold press, and insert the lead wire inserted into the terminal 2 3. The aluminum wire at the end is softened so that the aluminum wire is closely connected with the terminal 2. The aluminum stranded wire is composed of one or more aluminum wires, and the terminal is made of metal materials.

[0019] figure 2 As shown, heat-shrinkable sleeve 4 is used to wrap the aluminum enameled wire at the end of lead wire 3 of aluminum enameled wire reel 1 and the part of lead wire 3 close to aluminum ena...

Embodiment 2

[0021] Example 2: figure 1 As shown, insert the end of the lead wire 3 of the aluminum enameled wire reel 1 into the terminal 2, place it in the cold pressing equipment, and use a pressure of 4 kg to flatten the terminal 2 and the end of the lead 3 inserted into the terminal 2 together. , so that the terminal 2 and the end of the lead wire 3 are fixedly connected; then place it in a hot pressing device, and use a pressure of 4 kg and a temperature of 400°C for 6 seconds to heat the same part of the cold press, and insert the lead wire inserted into the terminal 2 The aluminum wire at the end of 3 is softened, so that the aluminum wire is closely connected with the terminal 2.

Embodiment 3

[0022] Example 3: figure 1 As shown, insert the end of the lead wire 3 of the aluminum enameled wire reel 1 into the terminal 2, place it in the cold pressing equipment, and use a pressure of 5 kg to flatten the terminal 2 and the end of the lead 3 inserted into the terminal 2 together. , so that the terminal 2 and the end of the lead wire 3 are fixedly connected; then place it in a hot pressing device, and use a pressure of 5 kg and a temperature of 500°C for 5 seconds to heat the same part of the cold press, and insert the lead wire inserted into the terminal 2 The aluminum wire at the end of 3 is softened, so that the aluminum wire is closely connected with the terminal 2.

Abstract

The manufacturing method of the aluminum reel terminal of the present invention is to directly insert the end of the lead wire (3) of the aluminum enameled wire reel (1) into the terminal (2), and first use cold pressing to flatten the terminal (2), so that The aluminum enameled wire reel (1) lead wire (3) is fixedly connected to the terminal (2), and then the aluminum wire inserted into the terminal (2) is melted by hot pressing, so that the aluminum wire and the terminal (2) are tightly connected. Connect, and form a slope (6) trapezoid at the stamping place; in order to ensure that the aluminum wire is not easy to break, the aluminum enameled wire reel (1) lead wire (3) is wrapped, and the lead wire (3) is close to the wire reel and terminal ( 2), wrap the aluminum wire with a heat-shrinkable sleeve (4), and wrap and seal the aluminum wire with a heat-shrinkable sleeve (4) and a glass fiber tube (5) on its periphery, so as to prevent the aluminum wire from being damaged due to bending. Disconnection, and to prevent external moisture or corrosive air erosion, suitable for use on the induction cooker.

Description

technical field [0001] The invention relates to a manufacturing method of an aluminum coil terminal. Background technique [0002] As a new small kitchen appliance, induction cooker has been popularized quickly due to its advantages of no open flame and high thermal efficiency. Important components, due to the increase in copper prices, aluminum enameled wires tend to replace copper enameled wires, and motor windings are changed from copper enameled wires to aluminum enameled wires to reduce production costs. [0003] The treatment method of copper enameled wire reel terminal is: the enameled wire is stripped first, then cold pressed on the copper terminal, and filled with tin. The wiring method of copper wire is very mature and used in mass production, but the material of aluminum wire determines the tinning treatment. Need to add flux dipping process before. [0004] At present, the treatment method of the aluminum wire reel terminal is: first remove the aluminum enamell...
