Embodiment 1

[0041] Example 1, such as Figure 1-3 , Figure 8 and Figure 9 As shown, the upper copper bar 1 and the lower copper bar 2 have the same size, the length is 150 mm, the width is 60 mm, and the thickness is 6 mm. The nailless flat riveting process of copper bars includes the following steps:

[0042] (1) Stamping the circular riveting joint 21 on the lower copper bar 2: the stamping machine uses a stamping machine tool, fixes the cylindrical mold on the interface of the stamping machine tool, and then starts the stamping machine tool to drive the cylindrical mold to press the surface of the lower copper bar 2, Make the back side of the lower copper bar 2 protrude to form a circular riveting head 21, and at the same time form a groove 23 on the surface of the lower copper bar 2 that is punched. Specifically, the diameter of the circular riveting head 21 is 8mm, the height is 3mm, and the groove 23 is formed due to the protruding circular rivet head 21, so the size of the gro...

Embodiment 2

[0049] Example 2, such as Figure 8 As shown, the upper copper bar 1 and the lower copper bar 2 have the same size, the length is 150 mm, the width is 60 mm, and the thickness is 6 mm. The nailless flat riveting process of copper bars includes the following steps:

[0050] (1) Stamping the circular riveting joint 21 on the lower copper bar 2: the stamping machine uses a stamping machine tool, fixes the cylindrical mold on the interface of the stamping machine tool, and then starts the stamping machine tool to drive the cylindrical mold to press the surface of the lower copper bar 2, Make the back side of the lower copper bar 2 protrude to form a circular riveting head 21, and at the same time form a groove 23 on the surface of the lower copper bar 2 that is punched. Specifically, the diameter of the circular riveting head 21 is 8mm, the height is 3mm, and the groove 23 is formed due to the protruding circular rivet head 21, so the size of the groove 23 is the same as that of ...

Embodiment 3

[0057] Example 3, such as Figure 8 As shown, the upper copper bar 1 and the lower copper bar 2 have the same size, the length is 150 mm, the width is 60 mm, and the thickness is 6 mm. The nailless flat riveting process of copper bars includes the following steps:

[0058] (1) Stamping the circular riveting joint 21 on the lower copper bar 2: the stamping machine uses a stamping machine tool, fixes the cylindrical mold on the interface of the stamping machine tool, and then starts the stamping machine tool to drive the cylindrical mold to press the surface of the lower copper bar 2, Make the back side of the lower copper bar 2 protrude to form a circular riveting head 21, and at the same time form a groove 23 on the surface of the lower copper bar 2 that is punched.

Abstract

The invention provides a copper bar nail-free flat riveted structure and a process method thereof. The copper bar nail-free flat riveted structure comprises an upper copper bar and a lower copper barwhich are arranged perpendicularly; two layers of concentric stepped circular holes which pass through the upper copper bar the thickness direction of the upper copper bar are formed in the upper copper bar; one side surface of the lower copper bar is provided with circular riveting joints which are suitable for being riveted into the circular holes with smaller diameters in the stepped circular holes; and process counterbores are formed in the circular riveting joints. According to the copper bar nail-free flat riveted structure and the process method thereof of the invention, riveting can berealized with no nails needed, other connecting parts are not required, the upper surface and lower surface of the copper bar nail-free flat riveted structure are flat, the appearance of the copper bar nail-free flat riveted structure is beautiful, the installation of other parts is not disturbed, and riveting means can be enriched.

Description

technical field [0001] The invention relates to the technical field of circuit connection in the electric power industry, in particular to a nailless flat riveting structure of a copper bar and a process method thereof. Background technique [0002] The copper bar plays the role of the main circuit conductor in the electrical cabinet and is an essential structural element. According to the requirements of low-voltage electrical technology, the space distance from the surface of three-phase copper bars A, B, and C to any conductor must be greater than or equal to 10mm. Such as Figure 10 As shown, in the traditional process, the copper bars are basically connected by screws and nuts. In the case of a relatively compact space, in order to ensure this safe distance, the distance between the copper bars has to be pulled due to the influence of the screws. This makes the space in the cabinet almost insufficient, and the size of the electrical cabinet will be developed in a compa...
