Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, specifically to a device for forming compact and small circuit breaker contact structures. Background Technology

[0002] Circuit breaker contacts are key components in high-voltage electrical appliances, and their performance directly affects the quality and service life of the appliance. The development of contact technology aims to improve contact effect, reduce contact resistance, and enhance short-time withstand capability. Circuit breaker contacts typically contain metal plates used to connect and form with conductors, allowing current to be conducted through the metal plates. The processing of these metal plates usually requires manual welding or pressing. Traditional processing equipment requires placing the metal plates and conductors at a processing station. However, since a complete conductor consists of several small conductors, the conductors are prone to scattering or even detaching from the processing station during pressing, requiring manual restraint. This processing method is complex, has a high risk factor during manual operation, and is inconvenient to operate. Furthermore, traditional processing equipment cannot restrain the metal plates in these small circuit breaker contacts, let alone restrain multiple conductors on the metal plates, making processing difficult.

One end of the clamping contact is located in the notch and can contact the workpiece to be processed, while the other end abuts against the transmission rod.

[0007] The effects of adopting the above technical solution are as follows: by setting up a clamping contact and a transmission rod in cooperation, when the transmission rod moves towards the workpiece to be processed, it can drive the clamping contact to clamp the workpiece to be processed. The clamping method is simple, the clamping and forming effect is good, and the operation is convenient.

[0008] As a further improvement of this utility model, the platform is provided with a processing groove corresponding to the positions of the first limiting piece and the second limiting piece, and the outer walls of the first limiting piece and the second limiting piece can contact the inner walls on both sides of the processing groove.

[0009] The effects of adopting the above technical solution are as follows: by setting a processing groove to accommodate the workpiece to be processed, when both the first limiting plate and the second limiting plate are placed in the processing groove, and the outer walls of the first limiting plate and the second limiting plate can contact the inner walls on both sides of the processing groove, the workpiece to be processed can be accommodated in the notch for processing.

[0011] The effects of adopting the above technical solution are as follows: by setting a long groove and a limiting groove, the long groove can be used to accommodate the long guide wire, and the limiting groove can limit one end of the long guide wire to prevent it from coming out of the long groove after being compressed. Connecting the long groove with the processing groove and the limiting groove makes it easier to place the long guide wire to be processed.

[0012] As a further improvement of this utility model, a through groove is provided between the processing groove and the long groove, which runs vertically through each other.

[0013] The effect of adopting the above technical solution is that by setting through grooves to accommodate the metal sheet to be processed in a local area, the metal sheet can be placed more stably on the processing station, and the metal sheet will not come out of the processing station when the clamping device clamps the guide wire on the metal sheet, thus improving the stability during processing.
