Described adsorption mechanism 14 comprises the blanking channel 17 that one end is communicated with the second die, described blanking channel 17 other ends are communicated with suction assembly, also comprise suction box 23, this suction box 23 is flexibly connected with lower bolster 10, and blanking channel 17 is communicated with suction assembly by suction box 23;
As shown in Figures 4 and 5, described suction assembly comprises air exhauster, efferent duct 22 one end of this air exhauster are stretched in suction box 23 and are communicated with blanking channel 17, the efferent duct 22 of described air exhauster is plastic telescopic pipe, suction assembly also comprises two symmetrical ventilating boards 18, these ventilating board 18 one end are located in blanking channel 17, the other end is located in suction box 23, this ventilating board 18 is rotationally connected with blanking channel 17, stretching into efferent duct 22 ends of the air exhauster of suction box 23 wears ejaculation one ventilating board 18 and is connected with this ventilating board 18, in suction box 23 bottoms, be provided with a cam 19, these cam 19 turning cylinders 20 are placed in the middle part of two ventilating boards 18, the axle center of turning cylinder 20 is greater than turning cylinder 20 axle center to the distance of a ventilating board 18 and to be less than the plate of ventilating board 18 long to the curvilinear surface longest distance of this cam 19, suction box 23 is stretched out in described turning cylinder 20 one end, and these turning cylinder 20 external parts are connected with motor.
Described patrix and counterdie are made by PMMA material, this material price is cheap, moderate strength and easily processing, greatly save molding cost.
On mould, remove cross cutting waste material function and be mainly the binder by patrix holding pad 16 and eject waste material with drift 15, counterdie is installed suction box 23 and is connected the mode that realizes suction under upper top with air exhauster or dust catcher and removes waste material.
The course of work of this patent:
Needing the first operation of the material of cutting is exactly first to place it on the die block 9 of this mould, and by correcting, follow closely 6 its location is fixed, by corrosion cutter 21, it is carried out to punching processing, now sweeping away the waste material that comes can be by the drift through hole that coordinates with corrosion cutter 21 on counterdie toward whereabouts, enter into and collect waste material mechanism, yet can be because drift retraction or the situation such as be just bonded at below punching when the punching causes waste material to stick on material for the waste material of cohesive material;
The first drift 7 on mould can position to this material the punching in hole, in order to the location of subsequent processing, uses;
A pair of jig 12 consists of two groups of identical signs, two groups identify the corresponding two ends that are located at corrosion cutter 21 and shedding mechanism 8 respectively, when material enters into discharging operation, can to jig 12, accurately find the position corresponding with the second drift 15, made hole by this, and then the locating hole sweeping away by the first drift 7 positions fixing;
Now material enters into after discharging operation, holding pad 16 when patrix moves down on shedding mechanism 8 first contacts punched material and leans on the elastic compression material of spring 3, because making holding pad 16, moves to cope match-plate pattern 1 direction by spring 3, thereby again it is rushed to waste material after exposing the second drift 15 by bore of the punch, spring 3 second drift 15 when normal condition can not reveal holding pad 16 outsides, open subsequently air exhauster, make waste material pass through blanking channel 17, suction box 23 and efferent duct 22 are siphoned away by air exhauster, thereby in realization, depress the process of suction, spring 3 designs herein can be played cushioning effect in drift and punching corresponding matching, can in this process, adjust at any time positions of materials, it is more accurately coordinated corresponding,
Two ventilating boards 18 that are provided with in suction box 23, rotation by cam 19 can realize two ventilating boards 18 around axle left-right rotation, again because a ventilating board 18 is communicated with fixing with telescopic flexible plastic efferent duct 22, so the mouth of pipe of this efferent duct 22 can change by corresponding occurrence positions along with the rotation of ventilating board 18, the wind speed that now ventilating board 18 extends to the part in blanking channel 17 and will provide air exhauster exerts an influence, so just can better to waste material, carry out exhausting suction, reduce waste material and be attached to the probability on the second drift 15 or material.
Because the turning cylinder 20 of cam 19 is placed in the middle part of two ventilating boards 18, the axle center of turning cylinder 20 is greater than turning cylinder 20 axle center to the distance of a ventilating board 18 and to be less than the plate of ventilating board 18 long to the curvilinear surface longest distance of this cam 19, so cam 19 can touch respectively two ventilating boards 18 when rotating, the ventilating board 18 touching with cam 19 can be driven and move to left or move to right by cam 19, now extend into two ventilating boards 18 of blanking channel 17 the insides owing to being rotationally connected with blanking channel 17, so ventilating board 18 run-off the straights that touched by cam 19, thereby change the ventilating opening size in blanking channel 17, when ventilating opening diminishes, wind speed is in the situation that air quantity is constant, reduce air-out area, will increase wind speed, therefore strengthen the effect of waste suction material.
The second drift 15 in discharge process is less than the diameter of the drift on corrosion cuttves 21 is the waste material being attached to below material hole in order better to wash out, and do not affect the shape in made hole, the shape of described drift can be different, such as oval, circular etc., and the drift that will guarantee to corrode on cutter 21 is identical with the shape of the second drift 15.
Upper and lower mould is controlled and is moved up and down precision by guide pillar 5 and guide column sleeve 11, thus the positional precision when guaranteeing the quality of fit of drift and die and rushing waste material.
This mould also comprises limited block, and limited block is enclosed within fixed head 2 and connects on the screw of stripper 4, and stripper 4 use are fixed on spring 3 jack-up between stripper 4 and cope match-plate pattern 1 and control ejection height with the limited block being enclosed within on screw.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model scope and improvement etc., within all should still belonging to this patent covering scope.
