S2.1, the horizontal moving mechanism 12 drives the two clamping mechanisms 2 to extend into the rolled product 5 from the corresponding clamping grooves 41, and each clamping mechanism 2 respectively clamps the inner side and the outer side of the rolled product 5.
S2.2, the forming mechanism 4 in the rolled product 5 is pulled out, and the horizontal driving mechanism 35 drives the supporting block 33 to synchronously extend into the rolled product 5 in the process of pulling out the forming mechanism 4. Specifically, since the two clamping mechanisms 2 apply pressure to the inner wall and the outer wall on the left side and the right side of the rolled product 5 simultaneously, and the supporting block 33 applies upward supporting force to the inner wall on the upper side of the rolled product 5 simultaneously, smooth blanking and no core pulling are ensured when the forming mechanism 4 is pulled out.
S3, the two left and right driving mechanisms 21 respectively drive the two clamping mechanisms 2 to be far away from each other, and meanwhile, the up and down driving mechanism 34 drives the supporting block 33 to move downwards. During the downward movement of the support block 33, the support block 33 remains in contact with the inner wall of the rolled product 5.
S4, the lifting mechanism 1 drives the rolled product 5, the two clamping mechanisms 2 and the supporting block 33 to move, when the rolled product 5 moves to a designated position, the two clamping mechanisms 2 are opened, and the two clamping mechanisms 2 and the supporting block 33 are separated from the rolled product 5. In actual working conditions, the specified position can be a blanking belt.
In the blanking process: the rolled product 5 is in a clamping and fixing state, so that the rolled product 5 is prevented from being deformed in an uncontrolled manner when the forming mechanism 4 is pulled out, and particularly, the inner wall of the upper side of the rolled product 5 is prevented from being deformed in a downward protruding manner. In the blanking translation process, the two clamping mechanisms 2 move towards the directions away from each other under the action of the two left and right driving mechanisms 21 respectively, at this time, the supporting block 33 moves downwards under the action of the upper and lower driving mechanisms 34, so that the auxiliary supporting mechanism 3 keeps in contact with the upper inner wall of the rolled product 5, and accordingly the upper inner wall of the rolled product 5 is continuously supported, downward protruding deformation of the upper inner wall of the rolled product 5 in the rolling process can be prevented until rolling is completed, and the rolled product 5 is formed into a flat shape.
Variation II
Based on a second preferred embodiment, the working method for the long-cell auxiliary support blanking device provided by the invention comprises the following steps: for step 2, it is also possible to:
s2.1, the horizontal moving mechanism 12 drives the two clamping mechanisms 2 to extend into the rolled product 5 from the corresponding clamping grooves 41, and enables each clamping mechanism 2 to clamp the inner side and the outer side of the rolled product 5 respectively, and meanwhile, the horizontal moving mechanism 12 drives the supporting block 33 to extend into the rolled product 5 from the corresponding supporting grooves 42, and enables the supporting block 33 to be in contact with the inner wall of the rolled product 5.
S2.2, the forming mechanism 4 in the rolled product 5 is pulled out. Specifically, since the two clamping mechanisms 2 apply pressure to the inner and outer walls on the left and right sides of the rolled product 5 at the same time, the supporting block 33 applies upward supporting force to the inner wall on the upper side of the rolled product 5, and smooth blanking and no core pulling are ensured when the forming mechanism 4 is pulled out.
