Problems solved by technology

[0003] At present, the ground socket panel and the upper cover are all produced by the casting process in the whole industry. The disadvantages are: (1) The copper needs to be smelted into a liquid state (1200°C) before casting, which will cause atmospheric air during smelting. Pollution; (2) During smelting, the copper loss is relatively large, about 8%; (3) Due to the casting process, the copper temperature needs to be around 1200°C, so the casting mold is too damaged. Generally, a set of molds is produced in 7000- In the case of 10,000 molds, it will be scrapped, and the mold needs to be well maintained
(4) The technical requirements are high during production, and the production efficiency is low. Because the casting process is easy to produce pores and sand holes, the product yield is low, so the production cost is high, and the product quality cannot be improved.

Embodiment 1

[0017] Embodiment 1: a kind of manufacture method of copper panel of ground socket, the copper rod that grade is H59, diameter is Φ50 is cut into the copper block of 30% more weight than copper panel finished product (see Fig. 1-Fig. 4), and copper block Heat until it turns red, and the forging die (see Figure 4-9) is installed in a friction press with a pressure of no less than 600 tons, and the copper block that has been burned to red is clamped into the forging die (see Figure 9) with pliers , At this time, immediately turn on the friction press for stamping and forming, and then use a punch and a special mold to punch holes and trim edges to obtain a finished copper panel (see Figure 1-Figure 4). The heating temperature of the copper block is 600°C.

Embodiment 2

[0018] Embodiment 2: A method for manufacturing a ground socket copper upper cover, cutting a copper rod with a grade of H59 and a diameter of Φ50 into a copper block with a weight 30% more than the finished copper upper cover, heating the copper block until it turns red, and forging The mold is installed in a friction press with a pressure of not less than 600 tons. The copper block that has been burned to red is clamped into the forging mold with pliers. At this time, the friction press is immediately turned on for stamping, and then punched with a punch and a special mold. , Trim the edge, and make the copper upper cover finished product. The heating temperature of the copper block is 600°C.

Embodiment 3

[0019] Embodiment three: a kind of manufacture method of copper panel of ground socket, the copper rod that grade is H58, diameter is Φ50 is cut into the copper block of 30% more weight than copper panel finished product (see Fig. 1-Fig. 4), and copper block Heat until it turns red, and the forging die (see Figure 4-9) is installed in a friction press with a pressure of no less than 600 tons, and the copper block that has been burned to red is clamped into the forging die (see Figure 9) with pliers , At this time, immediately turn on the friction press for stamping and forming, and then use a punch and a special mold to punch holes and trim edges to obtain a finished copper panel (see Figure 1-Figure 4). The heating temperature of the copper block is 500°C.

Abstract

This invention relates to earth socket copper panel and its copper cover process method, which comprises the following steps: cutting copper bar with name as H58-H60 and diameter as Phi45-Phi60 by proportion into copper blocks with weight 25%-35% more of copper panel or cover and heating the blocks till red; Fixing the forge tool into friction pressure machine with no less than 600 tons; clamping the red copper blocks into forge tool mode for shaping by friction pressure machine; then using impact bed and special mode tool for whole opening, cutting to process copper panel or copper cover to get final product.

Description

technical field [0001] The invention relates to a method for manufacturing a ground socket copper panel and a copper upper cover. Background technique [0002] With the improvement of people's living standards, people use more and more electrical appliances in their work and life. It is not suitable to use wall sockets to obtain power or signal sources, and there are many disadvantages. For this reason, people have designed some ground sockets (floor sockets). When not in use, the socket can be completely retracted into the ground (floor), and can bounce (jump up or open) from the ground (floor) when in use, eliminating the need for external connections and eliminating unsafe factors caused by wires . The Chinese market has been using ground sockets since 1992. Ground sockets include panels, upper covers, functional parts, terminal block components, opening and closing mechanisms, insulating mats, etc. Panels and upper covers are the main parts of ground sockets.
