Embodiment 1

[0064] Prepare HF8061 aluminum alloy composite product, specifically according to the following steps:

[0065] 1. Roll Gap Compensation

[0066] S01: Set the calibration pressing force;

[0067] In the step of bonding the HF8061 alloy, first set the calibration pressing force on the rolling mill, and the calibration pressing force is set to 100 tons;

[0068] S02: Position calibration;

[0069] The rolling mill starts calibration after receiving the calibration command, record the initial position of the upper oil cylinder on the operation side as Y1, and the initial position of the upper oil cylinder on the transmission side as Y2;

[0070] S03: Compensation calibration;

[0071] After performing the S02 step, the pressing device starts to run at a speed of 1.5mm / s under the drive of the motor. When the upper and lower work rolls just contact, the pressing force reaches 50 tons at this time, and the pressing device stops running; At this time, the upper cylinder starts t...

Embodiment 2

[0080] To prepare the HF8061 aluminum alloy composite product, the specific steps are the same as in Example 1, except that the calibration pressing force in step S01 is set to 170 tons.

Embodiment 3

[0082] To prepare the HF8061 aluminum alloy composite product, the specific steps are the same as in Example 1, except that the calibration pressing force in step S01 is set to 145 tons.

Abstract

The invention relates to a metal composite material bonding and rolling method for overcoming defects of bubbles and skin material deviation. The metal composite material bonding and rolling method comprises the following steps of (1) pre-swinging position calibration, specifically, acquiring initial calibration positions Y1 and Y2 of pressure devices on the operation side and the transmission side of a rolling mill during bonding pass rolling; (2) compensation calibration, specifically, acquiring final calibration positions X1 and X2 of the pressure devices on the operation side and the transmission side of the rolling mill when the set pressing force for calibration is reached; and (3) gap difference value determination, specifically, calculating the gap difference value Z of the pressure devices on the operation side and the transmission side through a displacement calibration method, performing Z value compensation on a compression roller, wherein Z is equal to (X1-Y1)-(X2-Y2). According to the metal composite material bonding and rolling method, position compensation is carried out in advance in a static compensation manner, a dynamic adjusting function of a pressing oil cylinder is omitted in the bonding process, and a constant roll gap of the rolling mill is kept in the whole bonding and rolling process; and compared with conventional dynamic leveling, the problem that askin material deviates in the bonding process is solved, and the probability of bubble generation is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of improving the manufacturing process of metal composite materials, and more specifically, relates to a bonding and rolling method of metal composite materials for improving air bubbles and deviation defects of leather materials. Background technique [0002] There are always two thorny problems in the production process of metal composite materials in hot rolling. One is that air bubbles are easily generated between the composite layers during the bonding process of the composite materials in hot rolling, which reduces the qualified rate of finished products; The upper leather material is easy to deviate during the bonding process, resulting in a decrease in the edge compounding rate of the finished product. [0003] Strip deviation is the lateral instability evolution process in which the rolling system loses symmetry under the initial factor of lateral asymmetry, and the center line deviates and expands ...
