The principle of the invention is as follows:
the invention designs a set of automatic circle rolling, electric heating and joint self-closing device. The core column is heated by introducing current into the core column, the amorphous foil is heated by heat conduction of the core column, automatic edge rolling is realized by the designed clamping device, the pipe side joint is automatically closed by controlling heating temperature and time, and the amorphous is formed in an overcooling liquid phase area with excellent plastic deformation performance. The thickness of the microtube is regulated and controlled by a mode of stacking and heating two amorphous foils to close gaps between the two amorphous foils.
The invention utilizes the clamping device to successfully realize the following four processes:
(1) the folding plate pops up, and when the stem descends, the stand is pressed and descends therewith, and because the lower end of the stand is in fit with the U-shaped frame in an inclined plane form, the U-shaped frame slides outwards, the folding plate pops up, and the amorphous foil is pressed, so that most area of the folding plate is attached to the stem, and the automatic edge rolling of the amorphous foil is realized when the die is closed.
(2) The sliding block goes down and the folding plate is folded. The upper die plate continues to move downwards, the sliding block can be pressed to move downwards, and meanwhile, the folding plate below the sliding block is also driven to be folded.
(3) And locking the sliding block. When the upper template descends, the U-shaped frame and the L-shaped frame are pushed to slide outwards, and the hole in the sliding block is finally embedded by the convex sliding block, so that the sliding block is kept still at the lowest position. The slide block presses the folding plate so that it cannot be ejected.
(4) And (4) moving the sliding block upwards. After the molding is finished, the rear core column moves upwards, the upright column also moves upwards due to the contraction of the spring 1, the convex sliding block is retracted into the sliding groove, the sliding block is pulled back to the highest position due to the contraction of the spring 2, and the folding plate is folded at the moment.
The four processes meet the requirement of automatic rounding of the amorphous foil, and the device can be repeatedly used, so that the possibility is provided for efficient preparation of the amorphous foil.
