Technical Field
[0001] The utility model relates to the technical field of metal composite plate processing equipment, in particular to a cold composite rolling mill for aluminum alloy brazing composite plates. Background Technique
[0002] The aluminum alloy brazing composite plate is a composite material plate with an aluminum alloy as the base plate, and is composite with other metal materials on one or both sides through a brazing process. This composite plate is commonly used in fields such as aerospace, automotive manufacturing, rail transit, electronics, and construction, and has the advantages of light weight, high strength, and corrosion resistance.
[0003] The cold composite rolling mill for aluminum alloy brazing composite plates is a device specifically used for cold rolling processing of aluminum alloy brazing composite plates. The cold composite rolling mill rolls the aluminum alloy brazing composite plate with a certain pressure through two or more rolling rolls. During the rolling process, the composite plate undergoes plastic deformation under the action of the rolling rolls, thereby changing its thickness, flatness, surface quality, etc.
[0004] After the existing cold composite rolling mill for aluminum alloy brazing composite plates finishes rolling, it will directly perform winding, and cannot perform edge grinding and polishing according to the width of the rolled composite plate. This makes it possible for there to be burrs on both sides of the composite plate, which will affect the product quality and may also hurt the hands of the staff. In view of the above problems, a cold composite rolling mill for aluminum alloy brazing composite plates is proposed. Content of the Utility Model
[0005] The purpose of the utility model is to provide a cold composite rolling mill for aluminum alloy brazing composite plates, which solves the problem in the background technique that edge grinding and polishing cannot be performed according to the width of the rolled composite plate.

[0035] Working principle: First, turn on the first braking motor 3. The output end of the first braking motor 3 rotates to drive the first gear 17 to rotate, thereby driving the straight rack 1 and the slider 4 to move downward along the first chute 6 according to the thickness to be rolled until the distance between the two rolling rolls 19 is set to the thickness to be rolled. Then, turn on the second braking motor 5. The output end of the second braking motor 5 rotates to drive the rotating shaft 16 and the rolling rolls 19 to rotate. Then, roll the aluminum alloy brazing composite plate between the two rolling rolls 19, and the aluminum alloy brazing composite plate can be rolled. If there are rolling requirements for different thicknesses, only the distance between the two rolling rolls 19 needs to be changed. Then, the aluminum alloy brazing composite plate slides along the top of the third U-shaped plate 15. Then, turn on the fifth braking motor 27. The output end of the fifth braking motor 27 rotates to drive the grinding wheel 26 to rotate. Then, turn on the fourth braking motor 21. The output end of the fourth braking motor 21 rotates to drive the second gear 20 to rotate, thereby driving the unilateral rack 23 and the limit rod 24 to slide along the inner wall of the second chute 25 until the distance between the two grinding wheels 26 matches the width of the aluminum alloy brazing composite plate. Then, the two grinding wheels 26 can grind both sides of the aluminum alloy brazing composite plate, thereby grinding off the burrs on both sides of the aluminum alloy brazing composite plate, ensuring the quality of the product and avoiding injury to the hands of the staff.
