The working principle is as follows:
the assembled upper die and the assembled lower die are installed on a punching machine, the upper pressing plate, the lower pressing plate and pressing plate screws are used for fixing the die and a machine tool, the servo feeder and the material erecting device are arranged in position and connected, and production can be carried out after the die is installed and debugged. And (4) flattening the coiled material by a material erecting device, and then feeding the coiled material by a servo feeder in a step pitch manner.
Placing the plate into the buoyancy pin 4, and starting to perform the first-step drawing process hole punching: the upper die is pressed down by the punching machine, the upper die base 7, the left stripper plate 13 and the right stripper plate 14 move downwards under the guiding action of the guide sleeve 8 and the guide post 2, when the left stripper plate 13 and the right stripper plate 14 contact the buoyancy lift pin 4, the buoyancy lift pin 4 starts to compress the supporting spring 29 under the pressure of the stripper plates (the rigidity of the buffer spring 34 is greater than that of the supporting spring 29), when the buoyancy lift pin 4 descends to the surfaces of the lower right female die 5 and the lower left female die 6, the two stripper plates respectively contact the lower right female die 5 and the lower left female die 6, at the moment, the punching machine continues to descend, the two stripper plates start to compress the buffer spring 34, the distance between the two stripper plates and the upper die base 7 is reduced, so that the first punch pin 23 passes through a through hole on the stripper plate and contacts with the plate, then the plate is stretched, and when the punching machine descends to a set position (namely, the position where the punch pin completes the shaping of the plate), the first punch pin 23 completes the drawing of the sheet material, and the punch returns upwards to finish the first step.
And then the feeder carries out step feeding, the plate enters the next station, and the second step of material stretching is started, and the process is consistent with that in the first step and is not repeated.
Then the feeder carries out step feeding, the plate sequentially enters the next station, the third step of primary reshaping machining, the fourth step of secondary reshaping machining, the fifth step of punching machining and the sixth step of trimming process machining are sequentially started, and finally the corner waste is cut off through the cutter 30.
The working principle of the buoyancy lifting pin 4 is as follows: the punched plate is placed in the clamping groove of the buoyancy lifting pin 4, and a certain free gap is reserved between the plate and the buoyancy lifting pin 4. When the punch descends, the upper die and the lower die start to be closed, and the lifting pin 4 also starts to move along with the descending of the die. Compression is effected by means of the lift pin support spring 29. Carry out moulding change in grinding the chamber by punching press panel, make panel and mould combine completely, at this moment, the punching machine begins the return stroke upwards, the lift pin makes progress the return stroke simultaneously, the return stroke is to a certain degree, carry out pay-off on next step by punching press panel and mould separation again, the good product of punching press can fall into lower mould exit, convey it to the turnover case in by the product conveyer again, and the corner waste material that the punching press came out is cut off by last mould cutter 30, so, product and waste material have reached autosegregation's effect completely, wait after the mould accomplishes first six steps single punching presses, just can set the punching machine into continuous motion, carry out continuous punching press.
Compared with the prior art, the utility model uses one mould to produce the outer baffle cover of the pump shell, the error is very small, the rejection rate is low, and the production cost is low; the utility model discloses only need a mould, join in marriage a punching machine, reduced the use quantity of punching machine, reduced the occupation of land space, alone can operate the completion, reduce the human cost, reduced operating personnel's potential safety hazard simultaneously. Additionally, the utility model discloses to towards the needle set to detachable, can accomplish the quick replacement towards the needle through quick detach bolt, improved the efficiency of production.
The utility model discloses maintenance convenient and fast, the noise is lower. The finished product after the punching press, in the past need carry out surface cleaning, and the outer fender lid of this device production directly cuts the leftover bits and pieces, need not to wash once more. In addition the utility model discloses use no oily stamping technology, environmental protection and energy saving improves production efficiency.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all the modifications and equivalents of the technical spirit of the present invention to any simple modifications of the above embodiments are within the scope of the technical solution of the present invention.
