Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-5 is please referred to, the present invention provides a kind of technical solution: a kind of punching press material guide device, including it is used for punching press guide
Interior stock guide 6, the first outer stock guide 3 and the second outer stock guide 4 of process and the lower die holder 11 installed for each components,
The buoyant plate 8 for simultaneously further including the material strip 7 for raw material transmission and holding up for material strip 7, finally includes being used for lower die holder 11
Fixed lower pallet 16 is supported, T-type is offered at the position for being internally located at buoyant plate 8 of material strip 7 and is punched slot 1, and material strip 7
The edge that one end is located at buoyant plate 8 is provided with flange feature 2, and material strip 7 is provided with forming process 5, buoyant at buoyant plate 8
The upper end outer surface of plate 8 is equipped with lower template 9 at T-type punching slot 1, and runs through at the inside center of lower template 9 and offer
Correcting hole cavity plate 10 is rushed, the outer surface of lower pallet 16 is connected with multiple groups bottom seat pad 12, and the outer surface of lower die holder 11 is close to surrounding top
Outer guiding post 13 is installed, and the outer surface of lower die holder 11 offers multiple groups fastening screw hole 14 and limited post 15 at angle.
The bottom end of buoyant plate 8 is provided with several nitrogen gas springs, and is installed on the first outer stock guide 3 on 8 top of buoyant plate
It is flexibly connected by screw with buoyant plate 8 with the second outer stock guide 4, can facilitate during molding, utilize press belt
Dynamic first outer stock guide 3 moves up and down with the second outer stock guide 4.
Lower template 9 and the upper end outer surface for rushing correcting hole cavity plate 10 are above the upper end outer surface of buoyant plate 8 in molding,
Therefore, the first outer stock guide 3 is adopted a split structure with the second outer stock guide 4, is disconnected in the side of lower template 9, is facilitated first
Outer stock guide 3 does with the second outer stock guide 4 and moves synchronously up and down.
The quantity of first outer stock guide 3 and the second outer stock guide 4 is two groups, and is led outside the first outer stock guide 3 and second
Flitch 4 is symmetrical about material strip 7 in the upper end of buoyant plate 8, and the material of the first outer stock guide 3 and the second outer stock guide 4 is to carry out
The Cr12 material of heat treatment, can be improved its wearability, to reduce the first outer stock guide 3 and the second outer stock guide 4 and material strip 7
Contact wear repeatedly.
Two group of first outer stock guide 3 is contacted with the side of material strip 7 with the second outer stock guide 4, and is equipped with 0.2-0.5mm
Guiding clearance, it can be achieved that forming process 5 before material strip 7 feeding guiding.
The upper end outer surface of interior stock guide 6 is provided with rectangular boss, realizes forming process by the contact with flange feature 2
The feeding guiding of material strip 7 after 5.
Material strip 7 is far from being equipped with end inductor at an end position of buoyant plate 8.
Material strip 7 is sent into the upper surface of buoyant plate 8 along feed direction, and material strip 7 enters bottom is held to be provided with stock supporting plate.
First outer stock guide 3 and the second outer stock guide 4 are shoulder structure, and the first outer stock guide 3 and the second outer stock guide 4
Height below shoulder is greater than 7 thickness of material strip and stock guide moves down sum of the distance.
In conclusion a kind of punching press material guide device is during use, firstly, in the outer surface of lower pallet 16 under
Feet 12 is installed, at the same time, in the process of molding, when upper mold and buoyant plate 8 contact, by the guide sleeve for being mounted on upper mold
It is precisely molded with the outer guiding post 13 for being connected to 11 upper surface of lower die holder, and punching stroke limit is carried out by limited post 15,
Prevent material ironed, while the first outer stock guide 3 and the second outer stock guide 4 are shoulder structure, it is tight by screw and buoyant plate 8
Gu before molding, material strip 7 is sent into forward guiding along the side of the first outer 3 shoulder lower part of stock guide, when upper mold and buoyant plate 8 connect
After touch, buoyant plate 8 moves downward under the action of the nitrogen gas spring of lower section, and drives the first outer stock guide 3 and the second outer stock guide 4
Move together, thus below the first outer stock guide 3 and the second outer 4 shoulder of stock guide the height in guide face be greater than 7 thickness of material strip with
Stock guide moves down sum of the distance, and in punching course, progress correcting hole and side edge punching first are rushed correcting hole cavity plate 10 and be fixed on down
In template 9, due to moving downward for the first outer stock guide 3 and the second outer stock guide 4 and buoyant plate 8, therefore led to lower template 9 and punching
Positive hole cavity plate 10 protrudes except buoyant plate 8, to avoid molding from interfering, while guaranteeing the intensity of lower template 9, therefore the first outer stock guide
3 with the second outer stock guide 4 be it is split type, disconnected in the side of lower template 9, and carry out empty avoiding, forming process above lower template 9
Each punching station before 5, the feeding of material strip 7 are directed through the first outer stock guide 3 and the second outer stock guide 4 and 7 side of material strip
Contact realize, the first outer stock guide 3 and the second 4 or so each one piece of outer stock guide, since the first outer stock guide 3 and second are led outside
Flitch 4 and the contact wear repeatedly of material strip 7, to improve the guiding accuracy for expecting outer stock guide, the first outer stock guide 3 and the second outer guide
Plate 4 uses Cr12 material, and is heat-treated, to improve its wearability, before forming process 5 starts, in the intermediate vector of material strip 7
On go out head be form of arcs T-type be punched slot 1, and by T-type punching slot 1 arc-shaped head carry out flange, erect
Flange feature 2 passes through the rectangular boss side of interior 6 upper end of stock guide protrusion and connecing for flange feature 2 since forming process 5
The feeding guiding of material strip 7 is realized in touching, on the last one station, is separated material strip 7 with product by cut off operation, needed for obtaining
Stamped part, it is practical.
