Description

Technical Field

[0001] This utility model relates to the field of electrical components, specifically to a flattening mold for copper tubes in switch cabinets. Background Technology

[0002] Copper conduits in switchgear primarily serve as conductors and connectors, offering the following advantages: 1. Excellent conductivity: Copper exhibits excellent electrical conductivity, effectively transmitting current and reducing power loss; 2. High mechanical strength: Copper conduits possess high mechanical strength, enabling them to withstand certain mechanical stresses within the switchgear, ensuring the safe operation of electrical equipment; 3. Strong corrosion resistance: Copper materials have good corrosion resistance, allowing for long-term use in humid or corrosive environments, extending the service life of the switchgear; 4. Reliable connection: Copper conduits can be reliably connected to other electrical components, ensuring circuit stability and safety.

[0003] In existing switchgear, some copper tubes need to be flattened, and then an opening needs to be made at the flattened part of the copper tube to meet the connection requirements. However, in the current technology, there is no equipment that can simultaneously flatten the copper tube and make the opening at the same time. Based on this, the applicant has conducted in-depth research, which led to the creation of this case. Utility Model Content

[0004] This utility model provides a flattening mold for copper tubes in switch cabinets. Its main purpose is to overcome the problem that existing equipment cannot simultaneously flatten the copper tubes and form the opening at the same time.

After the moving mold and the fixed mold are closed, the upper flattening grooves and the lower flattening grooves are aligned. After the moving mold and the fixed mold are closed, a plate opening is formed to make way for the open forming plate.

[0007] Furthermore, the lower pressing flat groove includes a first lower flat groove, a first lower inclined groove, and a first lower semicircular hole connected sequentially from left to right, and the first lower flat groove, the first lower inclined groove, and the first lower semicircular hole are connected and pass through each other from left to right; the upper pressing flat groove includes a first upper flat groove, a first upper inclined groove, and a first upper semicircular hole connected sequentially from left to right, and the first upper flat groove, the first upper inclined groove, and the first upper semicircular hole are connected and pass through each other from left to right, and the left end of the first lower flat groove and the left end of the first upper flat groove form the plate opening after the mold is closed.

[0013] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following advantages: A pre-cut opening is made at the point where the copper tube needs to be opened. Then, the pre-cut copper tube is placed on a fixed mold, and an opening forming plate is inserted into the pre-cut opening. The moving mold then moves downwards to extrude the copper tube, flattening it at the upper and lower flattening grooves. Simultaneously, under the action of the opening forming plate, the opening at the flattened part of the copper tube is also formed.
