[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0038] The utility model aims to provide a bimetallic composite strip preparation device to solve the problems of the existing preparation method that only a single composite strip can be prepared each time, the product has low composite strength, is easy to delaminate, has high power consumption, complicated process, and high comprehensive preparation cost.

[0039] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] It should be noted that when it is mentioned in this embodiment that a certain device is located at the "rear side" of another device, its meaning refers to the chronological order, that is, the processing technology corresponding to the device at the rear is later than the processing technology corresponding to the device at the front. When a certain device is located at the "rear side" of another device, in terms of spatial orientation, the device at the rear can be located on the left side of the device at the front, or on the right side of the device at the front, or at other positions.

[0041] Refer to Figures 1 to 12 , this embodiment provides a device for preparing a bimetal composite plate strip, including an aluminum rod 802 supply device, a steel strip supply device, a steel strip laminating device 14, an induction heating device 7, a continuous coating device 8, a cooling device 9, a grinding device 11, and a product collection device 12.

[0042] The aluminum rod 802 supply device is used to supply the aluminum rod 802. The steel strip supply device is used to supply the first steel strip and the second steel strip simultaneously. The steel strip laminating device 14 is used to laminate the first steel strip and the second steel strip. The induction heating device 7 is used to heat the laminated first steel strip and second steel strip.

[0043] The continuous coating device 8 includes a compaction wheel 801, an extrusion wheel 811, a guide plate 803, a coating die, and a scraper 812. The rim of the extrusion wheel 811 is provided with a wheel groove 8111, and the wheel groove 8111 is arranged in a circle along the rim. The compaction wheel 801 is used to roll and compact the aluminum rod 802 into the wheel groove 8111. The lower surface of the coating die is provided with a material blocking block 8051 and a through hole 8052. The material blocking block 8051 is inserted into the wheel groove 8111 to push the aluminum rod 802 in the wheel groove 8111 upward into the cavity of the coating die. The through hole 8052 communicates with the cavity of the coating die. The scraper 812 is used to scrape off the residual aluminum layer on the extrusion wheel 811. The cavity has a steel strip inlet and a composite plate strip outlet. The size of the steel strip inlet is configured to be adapted to the overall size of the stacked first steel strip and second steel strip, so that the heated first steel strip and second steel strip can pass through in a stacked state. The size of the composite plate strip outlet is configured to be adapted to the overall size of the two stacked composite plate strips, so as to coat a preset thickness of aluminum layer (this aluminum layer is called the aluminum layer 8101 on the opposite side) on the side opposite to the first steel strip and the second steel strip, obtaining two composite plate strips. The cooling device 9 is used to cool the composite plate strip in the laminated state. The grinding device 11 is used to grind the cooled composite plate strip. The product collection device 12 is used to traction-separate the two composite plate strips and wind them up separately.

[0044] The working principle of the device for preparing the bimetal composite plate strip in this embodiment is as follows:

[0045] When the extrusion wheel 811 rotates, the aluminum rod 802 is first flattened by the compaction wheel 801 in the groove 8111 of the extrusion wheel 811, and then enters the cavity of the coating die through the support of the material blocking block 8051. The first steel strip and the second steel strip are stacked and then pass through the coating die. By restricting the dimensional relationship between the steel strip inlet and the composite strip outlet, an aluminum layer is covered on each side of the first steel strip and the second steel strip facing away from each other, so as to obtain two composite strips in a stacked state.

[0046] Therefore, in this embodiment, two composite strips can be prepared simultaneously, improving production efficiency. In addition, in this embodiment, the process of the aluminum material flowing and coating is simple and energy-consuming is low. Compared with the rolling method, the electricity cost and equipment purchase cost can be reduced, and the comprehensive cost is lower. The extrusion forces of the aluminum material on the first steel strip and the second steel strip cancel each other out, and the overall force is uniform, which is beneficial to product forming and improves product quality.

[0047] When designing the size of the composite strip outlet, the overall size of the two composite strips expected to be obtained needs to be considered. According to the design expectation, if only the sides of the first steel strip and the second steel strip facing away from each other need to be covered with an aluminum layer, the width of the composite strip outlet should not be greater than the width of the steel strip inlet, and the height of the composite strip outlet should not be greater than the sum of the height of the steel strip inlet and the thicknesses of the two aluminum layers. According to the design expectation, if the thickness surfaces of the first steel strip and the second steel strip also need to be covered with an aluminum layer (this aluminum layer is called the thickness-side aluminum layer), the width of the composite strip outlet should not be greater than the sum of the width of the steel strip inlet and the thicknesses of the two aluminum layers.

[0048] When designing the size of the steel strip inlet, to reduce the frictional resistance, the height of the steel strip inlet should be slightly greater than the sum of the thicknesses of the first steel strip and the second steel strip, and the width of the steel strip inlet should be slightly greater than the widths of the first steel strip and the second steel strip. Exemplarily, the specific range of the slightly greater here can be 0 - 0.3 mm, and preferably 0.2 mm.

[0049] In this embodiment, the cross-sectional dimensions of the first steel strip and the second steel strip are the same (the cross-sectional dimensions can also be different), and are collectively referred to as the steel strip 804. The shapes of the steel strip inlet and the composite strip outlet are both rectangular. On this basis, when the first steel strip and the second steel strip pass through the coating die at a horizontal angle, if it is required that the aluminum layers 8101 on the sides facing away from each other of the first steel strip and the second steel strip have the same thickness, the axes of the steel strip inlet and the composite strip outlet should be collinear. It can be understood that those skilled in the art can also adjust the height relationship between the axes of the steel strip inlet and the composite strip outlet to obtain the required two aluminum layers 8101 on the sides facing away from each other.

[0050] As a possible example, in this embodiment, the steel strip supply device includes two steel strip pay-off devices 13, and the two steel strip pay-off devices 13 are respectively used to release the first steel strip and the second steel strip.

[0051] As a possible example, in this embodiment, the aluminum rod 802 supply device includes an aluminum rod pay-off reel 1 and an aluminum rod straightening device 2. The aluminum rods 802 released by each aluminum rod pay-off reel 1 are straightened by at least one aluminum rod straightening device 2. Specifically, in this embodiment, the number of aluminum rod pay-off reels 1 is two, and the two aluminum rod pay-off reels 1 supply aluminum rods 802 simultaneously. According to different actual requirements, those skilled in the art can also select other numbers of aluminum rod pay-off reels 1 to meet the aluminum material demand.

[0052] As a possible example, in this embodiment, the bimetallic composite strip manufacturing device further includes an aluminum rod cleaning device 3, and the aluminum rod cleaning device 3 is used to clean and dry the aluminum rods 802. In order to meet the cleaning requirements of the first steel strip and the second steel strip, corresponding cleaning devices should also be arranged. In this embodiment, the steel strip laminating device 14 has the functions of cleaning and drying. The first steel strip and the second steel strip are laminated at the entrance of the steel strip laminating device 14, and then the cleaning is completed inside the steel strip laminating device 14.

[0053] As a possible example, in this embodiment, the bimetallic composite strip manufacturing device further includes an aluminum rod turning device and an aluminum rod guiding device 6. The aluminum rod turning device is arranged behind the aluminum rod cleaning device 3 and is used to change the conveying direction of the cleaned aluminum rods 802. The aluminum rod guiding device 6 is arranged behind the aluminum rod turning device and is used to guide the turned aluminum rods 802 between the compaction wheel 801 and the extrusion wheel 811.

[0054] As a possible example, in this embodiment, the extrusion wheel 811 is located below the coating die, so it is necessary to send the aluminum rod 802 obliquely upward to the wheel groove 8111 of the extrusion wheel 811. Correspondingly, the aluminum rod turning device includes a first turning device 4 and a second turning device 5. The first turning device 4 is used to bend the aluminum rod 802 from horizontal to inclined downward, and the second turning device 5 is used to bend the aluminum rod 802 from inclined downward to horizontal, that is, the first turning device 4 and the second turning device 5 are used in combination to reduce the height of the aluminum rod 802. The aluminum rod guiding device 6 is used to bend the aluminum rod 802 from horizontal to inclined upward, so as to send the aluminum rod 802 obliquely upward between the compaction wheel 801 and the extrusion wheel 811.

[0055] As a possible example, in this embodiment, the coating mold includes a cavity 805, a male mold 807, and a female mold 808, and a material stopper 8051 is located on the lower surface of the cavity 805. A channel is provided inside the cavity 805, and the male mold 807 and the female mold 808 are located in the channel. The female mold 808 is located behind the male mold 807, and a cavity is formed between the male mold 807 and the female mold 808. A through hole 8052 is provided at the lower part of the cavity 805, and the upper end of the through hole 8052 is connected to the cavity, and the lower end of the through hole 8052 is connected to the wheel groove 8111. The steel strip inlet is located on the male mold 807, and the composite plate strip outlet is located on the female mold 808. The male mold 807 has a convex surface convex toward the side where the female mold 808 is located, and the female mold 808 has an inner concave surface concave toward the side away from the male mold 807. By limiting the direction of the convex surface of the punch 807 and the concave surface of the die 808, a flow direction that is the same as the conveying direction of the first steel strip and the second steel strip is formed in the cavity of the coating mold to guide the flow direction of the aluminum material in the cavity.

[0056] As a possible example, in this embodiment, the coating mold further includes a first nut 806 and a second nut 809. The first nut 806 is threadedly connected to the first end of the channel, and the first nut 806 presses and positions the convex mold 807. The second nut 809 is threadedly connected to the second end of the channel, and the second nut 809 presses and positions the concave mold 808. According to different actual needs, those skilled in the art may also fix the convex mold 807 and the concave mold 808 in other ways, such as locking the convex mold 807 and the concave mold 808 on the coating mold respectively by screws.

[0057] As a possible example, in this embodiment, the grinding device 11 includes a plurality of grinding wheels 111, and the plurality of grinding wheels 111 are respectively used to grind the thickness surfaces on both sides of the composite plate strip. In order to prevent the friction force applied by the grinding wheel 111 to the composite plate strip from affecting the conveying direction of the composite plate strip, in this embodiment, limiting rollers 112 are respectively provided on the front and rear sides of the grinding wheel 111.

[0058] As a possible example, in this embodiment, the product collecting device 12 includes a first collecting roller and a second collecting roller, and the two composite strips are respectively wound and collected by the first collecting roller and the second collecting roller.

[0059] As a possible example, in this embodiment, the bimetallic composite plate and strip preparation equipment also includes a control cabinet 10, which controls the operations of the aluminum rod 802 supply equipment, the steel strip supply equipment, the steel strip stacking equipment 14, the induction heating equipment 7, the continuous coating equipment 8, the cooling equipment 9, the grinding equipment 11, the product collection equipment 12 and the aluminum rod cleaning equipment 3 respectively.

[0060] As a possible example, in this embodiment, the number of the wheel grooves 8111 on the extrusion wheel 811 is two, and each wheel groove 8111 corresponds to an aluminum rod 802. Correspondingly, two material blocking blocks 8051 are provided at the lower part of the cavity 805, and the two material blocking blocks 8051 are respectively inserted into the two wheel grooves 8111. The lower surface of the cavity 805 is a mating arc surface 8053, so as to mate with the bending shape of the rim of the extrusion wheel 811. During operation, the material blocking blocks 8051 limit the movement direction of the aluminum material, forcing it to enter the cavity through the through hole 8052 at the lower part of the cavity 805.

[0061] This embodiment also provides a method for preparing a bimetallic composite strip, which uses the above-mentioned bimetallic composite strip preparation equipment, and includes the following steps:

[0062] Send the first steel strip, the second steel strip and the aluminum rod 802 to the continuous cladding equipment 8, and the continuous cladding equipment 8 outputs two composite strips.

[0063] Separate the free ends of the two composite strips in a stacked state, and the product collecting equipment 12 separately winds the two composite strips.

[0064] Since this method for preparing a bimetallic composite strip uses the above-mentioned bimetallic composite strip preparation equipment, it also has the corresponding advantages of the bimetallic composite strip preparation equipment, which will not be elaborated here.

[0065] In the present utility model, specific examples are used to elaborate the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
