Trimming is completed with a trimming convex die 17 when the upper die body 1 moves downwards along with a press; and (3) as the press continues to press downwards, the trimming and waste cutting combined mechanism fixed on the upper die body 1 rotates around the movable waste cutter rotating shaft 7 to cut waste with the lower die waste cutter 5 under the action of the cutting driving block 4 on the lower die body 18.
In the stamping process of the die, the key point is that the trimming and waste cutting combined mechanism firstly realizes the completion of conventional normal trimming with the trimming male die 17 in the stamping process; when continuing the punching press, go up mould activity waste material cutting off cutter 4 under the effect of cutting off drive block 4 on lower mould body 18, realize around activity waste material sword rotation 7 rotatory realizing with lower mould waste material sword 5 that the waste material cuts off, accomplished the two prefaces operation of general mould so far, effectively avoided cold stamping outer covering piece waste material to cut off the difficult problem that iron fillings splashed on the product, practiced thrift mould manufacturing cost simultaneously, also practiced thrift the frock cost for the host computer factory.
The specific stamping process is as follows:
stamping the die:
(1) before stamping, the die is opened, the nitrogen spring 15 is in a non-working state, and the prepressing acting force and the pressing core 16 are in a non-working state and reach the maximum stroke position;
(2) the trimming and waste cutting mechanism fixed on the upper die body 1 moves downwards along with the press, and the material pressing core 16 is firstly contacted with a plate on the trimming male die 17 and plays a role of pressing under the action of the nitrogen spring 15;
(3) the upper die body 1 continues to push the trimming and waste cutting mechanism and the pressing core 16 to move downwards, the upper end of the cutting edge of an upper die movable waste cutting knife 4 in the waste cutting mechanism is flush with the trimming cutting edge of the trimming and waste combined mechanism seat under the action of the return polyurethane 12, and the upper end of the upper die movable waste cutting knife 4, the trimming and waste combined mechanism seat 3 and the trimming male die 17 are combined to finish trimming under the further downward action of the press;
(4) when the press continues to perform downward punching, the upper die movable waste cutting-off knife 4 is in contact drive with the cutting-off drive block 2 on the lower die body 18 and is arranged on the drive wheel 11, so that the upper die movable waste cutting-off knife rotates around the movable waste knife rotating shaft 7 to cut off waste with the lower die waste knife 5, and the punching closing process is completed, namely trimming and cutting-off work is finished.
And (3) returning work of the die:
(1) the upper die body 1 moves upwards along with a press sliding block, the driving wheel 11 is separated from the cutting driving block 2 on the lower die body 18, the upper die movable waste cutting knife 4 is separated from the lower die waste knife 5, the upper die movable waste cutting knife 4 returns to be flush with the trimming cutting edge of the trimming and waste combining mechanism seat 3 under the action of the return polyurethane 12, the upper die movable waste cutting knife 4 and the trimming and waste combining mechanism seat 3 continuously rise along with the press, the upper die movable waste cutting knife 4 and the trimming and waste combining mechanism seat 3 are separated from the trimming male die 17, and at the moment, the material pressing core 16 continuously presses the plate under the pressure.
(2) And (3) continuing moving the press upwards, separating the pressing core 16 from the lower die body 18, the trimming convex die 17 and the plate along with the upper die body 1, completely opening the die, returning the press to the upper working state, and ending the die opening work of the die.
The description is made through the working principle as follows: the trimming and waste cutting integrated step-by-step stamping is a big characteristic of the die structure, the trimming and waste cutting work is completed at one time through the trimming and waste cutting integrated design, and the common outer cover normal trimming and waste cutting can be completed in different working procedures. Meanwhile, the defect that the conventional fixed cutting waste scrap iron chips bring to the surface of the appearance part to cause plate defects is solved, and even the molded surface of the die is damaged, and the die can continue to work only by maintaining the die.
Therefore, the design of the trimming and waste cutting integrated die with the structure can solve the problem that the conventional die can complete all trimming and waste cutting operations in two processes, so that scrap iron generated by cutting waste is prevented from flying to a product and a die molded surface, and the die development cost generated by increasing the processes is reduced. Meanwhile, the design and manufacturing technology of enterprises is improved, and the manufacturing cost of a host factory is reduced.
The above-mentioned is only for the description of the preferred embodiments of the present invention, and the above-mentioned technical features can be combined at will to form a plurality of embodiments of the present invention.
The present invention has been described in detail with reference to the accompanying drawings, and it is apparent that the present invention is not limited by the above embodiments, and various insubstantial improvements can be made without modification to the present invention.
