After the necking is completed, the upper die and the lower die are separated, the first elastic piece provides compression elastic force for the first ejector rod, the elastic force is vertically upward to drive the first necking slide block and the second necking slide block to vertically move upward, the first necking slide block and the second necking slide block respectively linearly move vertically upward and horizontally inward under the limitation of the trapezoidal guide rail, the end cover after necking is pushed out, the end cover after necking can be easily removed from the profiling convex piece, and the necking efficiency is high; after the first ejector rod rises to a certain position, the telescopic through hole is smaller than the limiting round table, and the limiting round table limits the rising position of the first ejector rod. The second elastic piece provides compression elastic force for the second ejector rod, and the elastic force is vertically upward to drive the profiling raised head to vertically move upward.
In the concrete implementation, the diameters of the third elastic piece and the fourth elastic piece are different, the diameter of the third elastic piece is larger than that of the fourth elastic piece, and correspondingly, the elastic force of the third elastic piece is larger than that of the fourth elastic piece; the lower template is also provided with a plurality of screw holes 31, and the height of the lower template can be adjusted through the screw holes, so that the height of the end cover opening shrinkage is adjusted, and the application range of the shrinkage die is further improved.
Above-mentioned amortization package end cover throat mould makes end cover opening part week circle throat reach the requirement state through toper slider and empty structure of rolling over, and whole process is accomplished with ordinary press through a set of mould, has following advantage: 1. compared with special necking equipment, the cost is saved, the cost for configuring a special necking equipment for each end cover is high, and the end cover can be finished by only one set of die and one general press; 2. the production speed is faster than that of special necking equipment; 3. the quality of the produced product is more stable than that of the special necking equipment.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that the technical solution of the present invention may be modified or substituted without departing from the spirit and scope of the technical solution of the present invention, and the present invention is intended to be covered in the scope of the present invention.
