Description

Technical Field

[0001] The invention relates to the field of copper plate smelting, in particular to an automatic feeding device for smelting copper plates. Background Art

[0002] In the processing and production of non-ferrous metal copper, horizontal continuous casting is the first process in the copper processing industry. If the quality of horizontal continuous casting is not good and the production efficiency is low, it will affect the product quality and production efficiency of subsequent rolling and drawing processes. The existing horizontal continuous casting method is divided into two stages: melting and casting. In the melting stage, the operator lifts the copper plate casting and transfers it to the melting and casting platform, cuts off the steel strip to separate the copper plates, and then uses a special clamp to clamp the copper plates and transfer them to the top of the melting furnace. At this time, the furnace door is opened, and the lower half of the copper plate casting is placed in the smelting pool. After the lower half of the copper plate casting is melted, the clamp is released to allow the copper plate casting to fall into the smelting pool for melting. Finally, the operator raises the clamp back to the starting position to continue to clamp the copper plate and transfer it to the smelting pool for melting. It can be seen that the traditional feeding method is manually completed by the operator. As the production scale becomes larger and larger, the manual feeding method will have problems such as high labor intensity, slow feeding speed, and low smelting efficiency.

[0048] See also Figure 6 , is a schematic diagram of the structure of the first clamp and the second clamp in an embodiment of the present invention.

[0049] In this embodiment, the structure of the second clamp is the same as that of the first clamp, including a clamp cylinder and a clamp, the clamp cylinder pushes the clamp to open and clamp the material, and when it moves to a preset position, the clamp cylinder pushes the clamp to open and put down the material. In other embodiments, the first clamp and the second clamp may also adopt other structures.

[0050] The following is an explanation of the implementation principle of the automatic feeding device for smelting copper plates described in this embodiment.

[0051] Workers use a forklift to transport the copper plate castings to be smelted and place them on the first trolley; the first trolley transports the materials from the feeding end of the storage platform to the discharging end, and flips the materials to place them vertically on the material storage table; at this time, the first positioning assembly and the second positioning assembly extend to block and position the materials, and the first trolley returns to the feeding end to load the materials; when the first trolley transports the second group of materials to the material storage table, the third positioning assembly extends to position the second group of materials on the rear side of the first group of materials. At this time, the second positioning assembly can be recovered to the positioning bracket. The second driving mechanism pushes the materials forward through the chain conveyor transmission, so that the materials fall on the correction plate of the adjustment mechanism. After the adjustment mechanism adjusts the placement angle of the materials, the lifting mechanism drives the first clamp to descend to clamp the materials and lift them to a certain height. At this time, the second trolley approaches the lifting mechanism to receive the materials, and transfers the materials to the first conveying roller, and then to the third trolley, and the materials are transported to the feeding transfer table through the third trolley. At this time, the clamp base on the third trolley is lifted, and after the clamp is opened to clamp the material, the clamp base, the clamp and the material return to the original position. The tenth cylinder flips the third trolley body so that the second clamp is located above the smelting furnace mouth. The second clamp puts the lower half of the material into the smelting furnace for smelting. After the lower half of the material is melted, the clamp is released so that all the material is put into the smelting furnace for smelting. The third trolley flips to its original position and repeats the process of putting the material into the furnace. The entire loading process does not require worker operation, has a high degree of automation, fast loading speed and high smelting efficiency. At the same time, it avoids workers from working in the high temperature environment around the smelting furnace for a long time, which is beneficial to the health of workers. In addition, it reduces electricity consumption and saves maintenance costs.

[0052] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
