Description

Technical Field

[0001] The present invention relates to the technical field of metal material processing, and particularly relates to a metal sheet pressing and compounding device. Background Art

[0002] The metal sheet compounding technology is a key process for realizing the manufacture of lightweight and functional materials. Traditional compounding processes mainly rely on hot rolling, explosive compounding or cold pressure welding, but there are the following technical bottlenecks in practical applications:

[0003] 1) Single pressing method leads to interface defects

[0004] Conventional roll pressing equipment mostly adopts fixed-spacing pressure rollers or a single pressure mode, which cannot meet the compounding requirements of different thicknesses and materials. One-time high pressure is likely to cause stress concentration in the sheet, and microcracks or delamination are likely to occur at the interface bonding part, especially poor adaptability to dissimilar metals (such as titanium-steel compounding with large differences in thermal expansion coefficients).

[0005] 2) Defects in cooling efficiency and residual stress control

[0006] Existing cooling systems mostly rely on natural cooling or single air cooling. Insufficient cooling rate leads to high-temperature interface rebound, insufficient curing of the metallurgical bonding layer, and warping deformation caused by the accumulation of residual stress.

[0007] 3) Low energy utilization rate and insufficient automation

[0008] Serious heat dissipation occurs in the heating area, and there is a lack of waste heat recovery design. At the same time, processes such as unwinding, alignment, and temperature control rely on manual adjustment, resulting in low production efficiency and difficult to guarantee compounding accuracy; therefore, we propose a metal sheet pressing and compounding device to solve this problem.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. In the present invention, for a metal sheet pressing and compounding device, by starting the first motor to drive the unwinding wheel to rotate, the lower sheet is unwound. At the same time, the second motor is started to drive the feeding wheel to rotate to realize sheet conveying. The upper sheet and the intermediate layer material are stored in the storage rack, and the upper sheet and the intermediate layer material are combined with the lower sheet through the guide wheels and then enter the heating mechanism. The sheet is heated by the electromagnetic heater. Heating enhances the activity ability of metal atoms and reduces the yield strength of the material, so that plastic deformation is more likely to occur during the pressing process. Then it enters the rolling mechanism, and the pressing and compounding of the sheets is realized through the extrusion between the pressing rollers. By starting the hydraulic cylinder to drive the upper mounting plate to move downward, and driving the lower mounting plate to move upward synchronously through the linkage rod and the rotating arm, the distance between the pressing rollers in multiple rolling assemblies can be adjusted to a gradually decreasing state, so as to realize step-by-step pressing and compounding. By starting the blowing motor to drive the rotating shaft and the fan blades to rotate, the sheet is quickly cooled. The cooling process quickly solidifies the metallurgical bonding interface formed at high temperature, prevents delamination caused by thermal stress rebound, and ensures the compounding effect.

[0024] 2. In the present invention, for the described metal sheet pressing and compounding equipment, by starting the air extraction pump, negative pressure is generated at the bottom of the air extraction frame, the air heated by the sheet is extracted, and is introduced into the air outlet frame through the air outlet pipe and blown out, so as to preheat the sheet in the heating shell. The temperature of the sheet is monitored by the first infrared thermometer, and the power of the electromagnetic heater is controlled to keep the temperature of the heated sheet balanced.

[0025] 3. In the present invention, for the described metal sheet pressing and compounding equipment, the temperature of the sheet is monitored by the second infrared thermometer. When the temperature is relatively high, the power of the blowing motor is controlled to increase, so as to enhance the cooling effect. While the rotating shaft rotates, the rotating plate is driven to rotate through the meshing of the driving bevel gear and the driven bevel gear, and drives the counterweight plate and the cross plate to perform circular motion. The cross plate drives the connecting disk to rotate. The counterweight plate is thrown outwards under the action of centrifugal force and compresses the compression spring. At the same time, the counterweight plate drives the connecting disk to rotate and move to the right through the cooperation with the trapezoidal guide rail, and approaches the linkage disk. As the monitored temperature rises, the blowing motor controls the rotation speed of the rotating shaft to increase, so that the connecting disk moves further horizontally. When the sector protrusion on the connecting disk inserts into the sector groove on the linkage disk, the connecting disk starts to drive the linkage disk to rotate, and drives the impeller to rotate through the linkage shaft, and cooperates with the internal structure of the water pump to realize water conveyance, so that the external cooling water is introduced through the water inlet of the water pump, and is introduced into the water inlet pipe through the water outlet, and then flows into the water outlet pipe through a plurality of annular pipes and is discharged, so as to cool the air while blowing, and enhance the cooling effect on the sheet.

[0026] 4. In the present invention, for the described metal sheet pressing and compounding equipment, multiple motors are coordinated to drive the unwinding, feeding and rolling pressure mechanisms to realize the precise alignment and efficient compounding of multiple layers of sheets; the electromagnetic heater is combined with the infrared thermometer to dynamically adjust the power, ensuring uniform and stable heating of the sheets, effectively activating the diffusion ability of metal atoms and reducing the yield strength, providing ideal conditions for plastic deformation; the innovative design of the multi-stage rolling pressure mechanism, through the hydraulic cylinder linkage to adjust the distance between the pressure rollers, realizes progressive pressing and compounding, avoiding interface defects caused by stress concentration; combined with the intelligent temperature control and centrifugal drive cooling system, the air cooling and water cooling are synchronously triggered to cooperate in cooling (the centrifugal counterweight plate drives the impeller to convey water), greatly improving the cooling efficiency, quickly solidifying the metallurgical bonding interface, and suppressing the risk of thermal stress rebound and delamination; at the same time, the air extraction pump is used to recover the waste heat in the heating area to preheat the unprocessed sheets, realizing the recycling of energy. The overall scheme combines automation, energy saving and high-precision control, significantly improving the interface bonding strength, product flatness and production efficiency of the composite sheets, and solving the technical bottlenecks such as large temperature fluctuations, uneven cooling and high energy consumption in the traditional process.

[0057] In this embodiment, during use, by starting the first motor 103 to drive the unwinding wheel 102 to rotate, the lower-layer board material is unwound. At the same time, the second motor 202 is started to drive the feeding wheel to rotate to achieve the conveyance of the board material. The upper-layer board material and the intermediate-layer material are stored through the storage rack, and the upper-layer board material and the intermediate-layer material are combined with the lower-layer board material through the guiding wheel 304, and then enter the heating mechanism 4. The board material is heated by the electromagnetic heater 402. Heating enhances the activity ability of metal atoms and reduces the yield strength of the material, so that plastic deformation is more likely to occur during the pressurization process. Then it enters the rolling mechanism 5, and the pressurized combination between the board materials is realized through the extrusion between the pressure rollers 504. By starting the hydraulic cylinder 505 to drive the upper mounting plate 503 to move downward, and driving the lower mounting plate 503 to move upward synchronously through the linkage rod 510 and the rotating arm 509, the distance between the pressure rollers 504 is adjusted.

By starting the blowing motor 805 to drive the rotating shaft 804 and the fan blades 803 to rotate, the board material is quickly cooled. The cooling process rapidly solidifies the metallurgical bonding interface formed at high temperature, prevents delamination caused by thermal stress rebound, and ensures the composite effect. By starting the air extraction pump 7, negative pressure is generated at the bottom of the air extraction frame 703, and the air heated by the board material is extracted and introduced into the air outlet frame 702 through the air outlet pipe 701 and blown out to preheat the board material in the heating shell 401. The temperature of the board material is monitored by the first infrared temperature detector 403, and the power of the electromagnetic heater 402 is controlled to keep the temperature of the heated board material balanced;

[0058] The temperature of the sheet is monitored by the second infrared thermometer 604. When the temperature is relatively high, the power of the blowing motor 805 is controlled to increase, thereby enhancing the cooling effect. While the rotating shaft 804 rotates, the driving bevel gear 806 meshes with the driven bevel gear 11 to drive the rotating plate 14 to rotate, and drives the counterweight plate 16 and the cross plate 15 to perform circular motion. The cross plate 15 drives the connecting disc 13 to rotate. The counterweight plate 16 is thrown outwards under the action of centrifugal force and compresses the compression spring 18. At the same time, the counterweight plate 16 drives the connecting disc 13 to rotate and move to the right through the cooperation with the trapezoidal guide rail 17, and approaches the linkage disc 907. As the monitored temperature rises, the blowing motor 805 controls the rotation speed of the rotating shaft 804 to increase, so that the connecting disc 13 further moves horizontally. When the sector protrusion on the connecting disc 13 is inserted into the sector groove 908 on the linkage disc 907, the connecting disc 13 starts to drive the linkage disc 907 to rotate, and drives the impeller 905 to rotate through the linkage shaft 906, and cooperates with the internal structure of the water pump 901 to realize water conveyance. Thus, the cooling water from the outside is introduced through the water inlet of the water pump 901 and led into the water inlet pipe 902 through the water outlet, and then flows into the water outlet pipe 904 through a plurality of annular pipes 903 and is discharged, so as to cool the air while blowing, and enhance the cooling effect on the sheet.
