Fig. 2 show the buckle of three kinds of different models.The present invention will buckle punching module, need to process other inhomogeneities
The buckle of type, it is only necessary to the corresponding buckle punching module is replaced on mold, so that it may to realize the production of different buckles.
The operation principle of the present invention：
Mold of the present invention uses autoloader self-feeding, and the production of punching press completion is caught using automatic collecting mechanism
Product.When defining web width according to buckle maximum length setting is concentrated, the distance between the pin 2 that drifts along, the pin 2 that drifts along effect are defined
It is that tailing correcting fixes material in order to avoid material sideslip in punching press.When punching machine drives 7 downward punching press of upper die holder, guide sleeve 10, correcting
Pin 11, guide sleeve 12, pilot pin 13 fix upper die holder 7 and 15 stamping position of lower die holder, ensure the punching press of punch 3 and molding concave die 5
Cooperation position, upper die holder 7 drive molding concave die 5 downward, material top and bottom and 4 two sides of molding concave die 5 and lower clamp plate punch mold insert
It squeezes, when upper die holder 7 continues downward, for punch 3 by material punching press into molding concave die 5, nitrogen gas spring 14 passes through external stripping plate pad
Plate 17 is that external stripping plate 18 provides enough buoyancies, ensures the grip force of molding concave die 5 and lower clamp plate punch mold insert 4 to material,
Material punching press is not in loosen deformation into material when molding concave die 5 by punch 3.When being lifted on punching machine, the drive of spring 16 is drifted along
Material is restored the height and position before punching press by pin 2 upwards, and nitrogen gas spring 14 drives lower clamp plate punch mold insert 4 slowly to revert to upwards
Punching press front position, punch 3 are also exited from molding concave die 5, and at this moment position-limit mechanism drives holding pad 9 to push in punching machine, holding pad 9
Thimble 8 is driven to push, thimble 8 drives 6 downward ejecting product of interior de- block, and at this moment material receiving mechanism picks out the product to fall down and completes punching
Press process.
Fig. 1 molds are realized modularized design by the design, and the punch clamp plate 1 of lower die holder 15 is for fixing punch 3, lower folder
Plate punch mold insert 4 is fixed for 3 position of punch, and shift in position when preventing 3 punching press of punch causes punch 3 to occur with molding concave die 5
Interference, leads to burn failure.By mold and punching head strap 1, punch 3, lower clamp plate punch mold insert 4, molding concave die 5, interior de- block 6
It realizes modularized design, is buckled in punching press different model, buckle a, buckle b, buckle c as shown in Figure 2, it is only necessary to replace different shaped
Number module, so that it may to realize that the buckle of different model produces, realize that mould bases is shared.Fig. 3 is molding concave die 5, Fig. 4 is lower clamp plate
It is punch 3, Fig. 8 and Fig. 9 is interior de- block 6, by module appearance and size that punch mold insert 4, Fig. 5, which are punch strap 1, Fig. 6 and Fig. 7,
Design is consistent, and fit dimension is consistent, realizes that module is exchanged.
This programme provide it is a kind of reduce the early development time newly buckled, reduce development cost, improve product economy effect
A kind of continuous die design of the common mode of the similar buckle mold of punching press of rate.
The series of detailed descriptions listed above is illustrated only for possible embodiments of the invention,
They are all without departing from equivalent embodiment made by technical spirit of the present invention or change not to limit the scope of the invention
It should all be included in the protection scope of the present invention.
