Description

Technical Field

[0001] The utility model relates to the technical field of production equipment arrangement in a nonferrous metal processing workshop, in particular to a workshop reconstruction structure of a copper belt bell-type heat treatment furnace. Background Art

[0002] In the production process of copper strip, it needs to go through multiple processing steps, from copper strip blank → copper strip rolling → heat treatment of in-process products → copper strip rolling → heat treatment of finished products → finishing, etc. Among them, the heat treatment of finished products is a production process to control the final product state and performance of the copper strip and eliminate the internal stress of the strip. It is an indispensable and important process in the production process of copper strip. Usually, this heat treatment is carried out in a bell-type heat treatment furnace.

[0003] During the production process, copper strips must be heat treated. One of the equipment used in this process is a bell-shaped heat treatment furnace. According to conventional designs, in order to allow the outer furnace cover to be lifted off the bell-shaped heat treatment furnace, the foundation is usually sunk. Figure 1 As shown, this structure requires taking stairs to the underground for auxiliary lifting during production. During production, an overhead crane is used to lift the bell-type heat treatment furnace cover from the bottom to the top, and then the copper coil is placed in the bell-type heat treatment furnace by the overhead crane, and finally the furnace cover is lifted back into the bell-type heat treatment furnace. Since the bell-type heat treatment furnace is relatively high, and when lifting the furnace cover, the furnace cover needs to be raised above the entire furnace group, and a certain amount of moving space is left. In this case, during production, the bell-type heat treatment furnace group area needs to be deepened to make a foundation furnace pit. In order to reduce investment, some companies need to use existing old factory buildings or standard factory buildings built by the government for transformation. The traditional pit design often has a high foundation construction cost, and during production, the staff need to enter the furnace pit to operate, the labor intensity of the workers is high, and the production safety is low. For this reason, we propose a workshop transformation structure for a copper belt bell-type heat treatment furnace. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1:

[0018] See also Figure 2The utility model provides a technical solution: a workshop reconstruction structure of a copper strip bell-type heat treatment furnace, comprising a bell-type heat treatment furnace 2 arranged on the floor 1 of the workshop and a copper strip coil 3 placed on the bell-type heat treatment furnace 2, a heat treatment furnace cover 4 is arranged on the outside of the bell-type heat treatment furnace 2, and a heat treatment furnace cover lifting device for lifting the heat treatment furnace cover 4 and a copper strip coil transferring device for transferring the copper strip coil 3 are also arranged on the workshop. Specifically, the heat treatment furnace cover lifting device comprises a first car 6 arranged in the workshop, and the The copper strip coil transfer device includes a second crane 7 arranged in the workshop, the first crane 6 and the second crane 7 are both arranged above the bell-shaped heat treatment furnace 2, and the second crane 7 is arranged below the first crane 6. Compared with the conventional design structure, the structure of the present application is to add a crane above the existing crane to lift the furnace cover of the bell-shaped heat treatment furnace. Since the furnace cover is light, the selected crane can be selected from some cranes with smaller loads, and the existing crane, i.e. the first crane 6 used to lift and transfer the copper strip coil 3, should be determined according to the copper coil produced. This configuration no longer requires a deep foundation furnace pit to place the bell-shaped heat treatment furnace, and can be placed directly on the ground. During production, the furnace cover of the bell-shaped heat treatment furnace can be lifted out by the upper crane, and then the copper coil can be put into the furnace by the lower crane, and then the furnace cover can be put back into the bell-shaped heat treatment furnace by the upper crane.

[0019] The first lathe 6 and the second lathe 7 do not overlap in the top view to avoid collision when lifting the heat treatment furnace cover 4 and the copper strip coil 3, thereby affecting the safety of the workshop.

[0023] A preferred technical solution is that a plurality of counterweights 11 are installed on the side of the sliding seat 9 away from the coil reel 10. The weight and quantity of the counterweights 11 can be configured according to the weight of the copper strip coil 3 to ensure that the sliding seat 9 can maintain balance when sliding in the slide groove 13 of the fixed frame 8.

[0024] The preferred technical solution is that a driving screw 14 is rotatably arranged in the slide groove 13, a driving motor 12 is installed on the side surface of the fixing frame 8, the driving motor 12 is electrically connected to the external control switch, the output shaft of the driving motor 12 penetrates into the slide groove 13 and is connected to the driving screw 14 through a coupling, the driving screw 14 is threadedly connected to the screw hole provided on the side surface of the sliding seat 9, the driving motor 12 drives the driving screw 14 to rotate so that the sliding seat 9 drives the copper strip coil to move, thereby moving the copper strip coil 3 to the bell-type heat treatment furnace 2 or removing it from the bell-type heat treatment furnace 2.

[0025] The L-shaped sliding seat 9 ensures that the coil reel 10 arranged thereon will not conflict with the already lifted heat treatment furnace cover 4 during the process of moving the copper strip coil 3 to the bell-shaped heat treatment furnace 2 .

[0026] The drive motor 12 is an electronic component commonly used in the prior art, and its specific structure, working principle and circuit connection are all well-known technologies and will not be described in detail here.
