Description
Technical field
The utility model relates to a kind of wiring board process equipment, more particularly, relates in particular to a kind of wiring board punching press stripper.
Background technology
Existing wiring board punching press stripper, as shown in Figure 4, mainly formed by public top board 10, the thimble 40 that re-packs set screw 30 and be located on the public top board 10 that re-packs 20, is threaded in 20 both sides that re-pack that is arranged on public top board 10 bottoms, be provided with the public affairs top 50 with through hole at public top board 10 tops, it is 20 relative that thimble 40 passes re-packing of through hole and bottom on the public top 50.During installation, at first 50 installation positions of inserting the Presser Dashing pressure head, the top of the public affairs on the public top board 10 are fixed, mainly be to cooperate the public top 50 of screw-clamped by pressing plate, then diel is installed, patrix is fixed on public top board 10 bottoms, counterdie is fixed on the base of staking punch below, during use, need to be according to the difference of every mold, adjust the length of the set screw 30 that re-packs, make itself and fixedly the length of thimble 40 adapt.There is following shortcoming in the stripper of said structure:
(1) existing public backform is in upper mode locking.Because public top 50 is to be fixed on the punch press by frictional force, if when mould is very large, own wt is very heavy, easily not tight; In addition, when large or red needle is a lot of when product, also can produce very large thrust during the material returned, also can cause easily the mould not tight, even come off, have potential safety hazard.
(2) thimble 40 and the re-pack set screw 30 on both sides of existing stripper by the centre matches and carries out the material returned, the set screw that re-packs 30 need to be carried out manual adjustments according to concrete product specification, it is inconsistent with middle thimble 40 length to occur easily, simultaneously, because manual adjustments is fully with operating personnel's qualification, also be prone to the inconsistent situation of set screw 30 left and right sides length that re-packs, uneven when causing taking off material, quality problems appear in product easily, mould also is prone to the shovel mould, the situation of broken needle, not only affect operating efficiency, also can increase maintenance cost.
(3) when installation mold, public top 50 needs use screw locking, and workman's qualification can affect the quality of locked mode, if for example inaccurate to mould, can cause the mould damage; Simultaneously, during installation mold, need many people compounding practice, patrix efficient is low.
(4) waste material, existing stripper, every mold all need to dispose public top, 20 need to cooperate with the set screw 30 that re-packs owing to re-pack, so re-pack and 20 design very longly; And every cover die all joins two set screw 30 that re-pack, and high material consumption and utilization rate are not high.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of compact conformation, easy to use, safe and wiring board punching press stripper that result of use is good are provided.
The technical solution of the utility model is achieved in that a kind of wiring board punching press stripper, comprise public top board, bottom public top board, be provided with and re-pack, wherein said public top board middle part is provided with at least three through holes, be provided with location-plate at public top board top, the location-plate upper surface be distributed with three with through hole counterbore one to one, in each counterbore, be equipped with material returned thimble, it is corresponding that described each material returned thimble passes through hole re-packing bottom public top board; Described public top board is fixedly connected with by hydraulic means with location-plate.
Above-mentioned wiring board punching press is with in the stripper, and wherein said location-plate bottom is distributed with the location counterbore, and location-plate passes the location counterbore by screw and is fixed on the staking punch of punch press.
Above-mentioned wiring board punching press is with in the stripper, and described hydraulic means is comprised of hydraulic cylinder and the locating piece that is fixed on the piston rod end of hydraulic cylinder, and hydraulic cylinder is connected with external hydraulic station pipeline; Described location-plate is respectively equipped with at least two T shape locating slots on the relative wherein two sides, be provided with the locating notch corresponding with each T shape locating slot at public top board, described hydraulic cylinder is arranged on the bottom of each locating notch, and described locating piece correspondence is located in each T shape locating slot.
Above-mentioned wiring board punching press is distributed with installing hole with in the stripper on the described public top board.
The utility model matches with public top board with hydraulic means by location-plate is set after adopting said structure, the simple and fast and firm difficult drop-off is installed so that the mounting means of public top board becomes; After adopting this structure, location-plate is disposable installation, and public top board is installed is no longer needed a product to cooperate a cover, can cooperate with patrix according to the positioning screw hole on the public top board to be fixed, and can greatly save die cost, and more greatly shortens the mold exchange time; Further, with original thimble and the mode that the set screw that re-packs matches, change three material returned thimbles into, and three material returned thimbles all are positioned on the public top board, and the spacing when re-packing is dwindled, and can dwindle the size that re-packs, save material, simultaneously, three material returned thimbles are fixed on the punch press by location-plate, and its length is consistent, do not need to regulate, the unbalanced problem that re-packs can not occur, guarantee product quality, can guarantee that equipment is not impaired yet.
