Description

Technical Field

[0001] The present invention relates to the technical field of cladding metal production, and in particular to a production device and process for a plurality of cladding metal composite materials. Background Art

[0002] Due to the high strength, high electrical conductivity and good thermal conductivity of copper and the light weight, easy processing, corrosion resistance and fast heat dissipation of aluminum, copper-aluminum layered composite materials are widely used in the thermal conductivity, heat dissipation, power and electrical, and communication shielding industries, achieving the goal of "saving copper with aluminum", alleviating the current situation of copper resource scarcity, and fully complying with the development concept of maximizing resource utilization and optimizing performance. The main preparation processes of copper-aluminum layered composite materials include explosive composite method, die casting method, cold rolling + diffusion composite method, core filling continuous casting composite method, casting and rolling method, etc. However, in the existing production process of composite metal materials, due to different customer requirements, the width of the composite metal materials is different, but the same production line can only produce composite metal sheets with the same width, which affects the production efficiency. Summary of the invention

[0003] The invention provides a production process of a multi-cladding metal composite material.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A production process for a multi-clad metal composite material, (1) melting an electrolytic low-titanium aluminum alloy ingot into aluminum alloy liquid, and then injecting the aluminum alloy liquid at a temperature of 680 to 800° C. into an aluminum liquid guide trough through a degassing box and a filter box;

[0006] (2) The copper strip is degreased and deoiled, then polished by a grinding roller, and enters a twin-roller continuous casting and rolling machine through an upper roller. The surface roughness of the upper roller in contact with the copper strip is Ra0.8-1.6 μm, and the roughness of the lower roller is Ra0.4-0.6 μm. Before casting and rolling, the asynchronous speed of the upper roller is set, and the upper and lower rollers are preheated to 160-200°C;

[0007] (3) The semi-molten aluminum alloy liquid formed by melting in the smelting furnace enters the degassing box and the filter box through the aluminum liquid guide groove, and the titanium boron wire is fed into the aluminum alloy liquid in the guide groove by the wire feeder for grain refinement. The control system measures the liquid level in the aluminum liquid guide groove by a camera to calculate the volume of liquid flowing through the aluminum liquid guide groove, and controls the wire feeding speed of the wire feeder according to the liquid volume; the wire feeder detects the wire feeding speed of the titanium wire by a detection wheel, and transmits the measured speed to the control system in real time to determine whether the ratio of the measured speed to the liquid volume is within a specified range. If the ratio of the wire feeding speed to the liquid volume is not within the range, the control system adjusts the wire feeding speed by controlling the speed of the drive motor 2 so that the wire feeding speed and the liquid volume are within the specified ratio range;

[0008] (4) After the grains are refined, the semi-molten aluminum alloy liquid begins to contact the copper strip at the boundary of the casting nozzle. The water flow rate is controlled to keep the temperature of the upper and lower rollers at 160-200°C. As the upper and lower rollers rotate through the casting zone, the different roughness of the upper and lower rollers and the speed difference of the asynchronous casting of the two rollers are used to generate friction shear force between the copper strip and the aluminum alloy melt, creating a disturbance of the aluminum alloy melt at the front end of the casting zone of the copper-aluminum composite process, generating a synergistic effect of rolling and deformation at the rear end of the casting, further removing the oxide film on the surface of the copper strip, and the aluminum surface just solidified. The grains containing oxide film are crushed and pressed into the aluminum matrix to obtain a copper-aluminum composite thin plate with fine grains and good interface bonding. The ends of the composite thin plates with different widths are clamped by production equipment; the composite thin plate is inserted between the two clamping blocks of the fixed unit in the slide slot, and the fixed unit is pulled by the traction rope, so that the fixed unit is relatively displaced in the slide slot of the base. Under the action of the slide slot, the distance between the two clamping blocks is reduced, so that the clamping force of the two clamping blocks on the composite thin plate becomes larger, and finally, driven by the traction rope, the base, the fixed unit and the composite thin plate are moved at the same time.

[0009] Furthermore, the production equipment includes a base, a slide groove is arranged on the rod body of the base, the width of the upper part of the slide groove is smaller than the width of the lower part of the slide groove, a plurality of mounting grooves are arranged on the two inclined surfaces of the slide groove, the distance between two adjacent mounting grooves is equal, a plurality of fixing units are installed in the slide groove, the fixing unit includes a first clamping plate and a second clamping plate, the first clamping plate includes an inclined plate and a straight plate, the upper end of the inclined plate is fixedly connected to the straight plate, the structure of the first clamping plate is completely consistent with the structure of the second clamping plate, the outer side surface of the inclined plate of the first clamping plate and the outer side surface of the inclined plate of the second clamping plate are both provided with sliding blocks, the upper end of the straight plate of the first clamping plate and the upper end of the straight plate of the second clamping plate are fixed to the connecting sleeve The connection is that the inner side surface of the inclined plate of the first clamp and the inner side surface of the inclined plate of the second clamp are both provided with clamping blocks, the side surface of the clamping blocks is an arc surface, and a plurality of clamping teeth are provided on the arc surface, the arc surfaces of the two clamping blocks are arranged facing each other, and a connecting piece is installed in the connecting sleeve, and the connecting piece is connected to the traction rope, the slider of the first clamp and the slider of the second clamp are both arranged in the mounting groove of the inclined surface of the slide groove, the first clamp and the second clamp are fitted with the inclined surface, and a plurality of composite thin plate strips with different widths can be fixed in the slide groove of the base through the fixing unit, when (N-1)*L1<the width L of the composite thin plate strip<N*L1, at this time, the end of the composite thin plate strip is fixed by N fixing units.

[0010] Advantages: The present invention clamps the ends of composite thin plate strips of different widths through production equipment; inserts the composite thin plate strip between the two clamping blocks of the fixing unit in the slide groove, and pulls the fixing unit through a traction rope, so that the fixing unit is relatively displaced in the slide groove of the base, and under the action of the slide groove, the distance between the two clamping blocks is reduced, so that the clamping force of the two clamping blocks on the composite thin plate strip becomes larger, and finally driven by the traction rope, the base, the fixing unit and the composite thin plate strip are moved at the same time.
