The utility model discloses a multi-hole blanking quick-replacing lower die structure. The multi-hole blanking quick-replacing lower die structure comprises a lower die base. Lower padding feet are fixed to the two sides of the bottom of the lower die base respectively through screws, outer guide posts are fixed to the two sides of the upper end face of the lower die base respectively, a lower padding plate is arranged on the upper end face of the lower die base, lower die plates are arranged on the two sides of the upper end of the lower padding plate, the upper end face at one end of each lower die plate is provided with a fixing groove, the lower die plates are connected with the lower padding plate and the lower die base in the mode that screws penetrate through the fixing grooves, a fixing insert is arranged between the two lower die plates, a quick-replacing insert is fixed to one end of the upper end face of the fixing insert through a screw, a hole matched with a knocking rod in shape and size is formed in the vertical direction on the same side of one end of the fixing insert, one end of the lower padding plate and one end of the lower die base, a hole matched with a positioning pin in shape and size is formed in the vertical direction on the same side of the other end of each lower plate, the other end of the lower padding plate and the other end of the lower die base, and the positioning pin is fixed into the hole. The multi-hole blanking quick-replacing lower die structure is simple and convenient to operate and maintain, cost is reduced, production efficiency is improved, and labor intensity of bench workers is relieved.

Description

A kind of porous punching quick change lower die structure
Technical field
The utility model relates to diel field, specifically, relates in particular to a kind of porous punching quick change lower die structure.
Background technology
Along with the development of electric utility, people require more and more faster to the speed of service of data, and the heat that powerful product produces in inside is also more and more, and heat radiation becomes a problem that must solve.For sheet metal component, at periphery, rushing a lot of apertures is a solution, but because the aperture of punching is many, and aperture is smaller again, for diel, edge of a knife intensity and service life are all more insoluble problems, the edge of a knife is due to intensity difference, often easily wearing and tearing, so counterdie will be made mold insert form, traditional way is that mold insert is made to overall structure, at stiff end, do hanging platform, lower bolster milling empty avoiding, be fixed on lower bolster, and so, because of mold insert thicker, the workload that line cuts is larger, cost increases, two while carrying out mold repair, need to be lower bolster, lower bolster, die shoe and screw, pins etc. are all pulled down, mold insert can be taken out, and change, and this structure causes inefficiency, be not suitable for the requirement of producing fast, and increased the labour intensity of pincers worker.
Summary of the invention
The purpose of this utility model is just to provide a kind of porous punching quick change lower die structure, and simple in structure, convenient for maintaining, reduces costs, and enhances productivity, and reduces pincers worker labour intensity.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions:
A kind of porous punching quick change lower die structure, comprise die shoe, described die shoe two bottom sides has been screwed respectively bottom seat pad, both sides, die shoe upper surface are fixed with respectively outer guiding post, the upper surface of die shoe is provided with lower bolster, these both sides, lower bolster upper end are provided with lower bolster, two described lower bolsters wherein offer holddown groove in the lower bolster upper surface of one end, described lower bolster passes holddown groove and described lower bolster by screw, die shoe connects, between two described lower bolsters, be provided with fixedly mold insert, this has fixedly been screwed quick change mold insert in one end, mold insert upper surface, described fixedly mold insert, lower bolster, the same side, die shoe one end vertical direction offers and the hole of knocking bar respective shapes and size, described lower bolster, lower bolster, other end the same side vertical direction of die shoe offers the hole of alignment pin respective shapes and size, in hole, be fixed with alignment pin.
Described fixedly insert shape is cuboid, and upper surface, described fixedly mold insert one end inboard, upright direction offers screw, and described fixedly mold insert bottom offers correspondingly knocks the hole of bar, the screw of the hole of corresponding alignment pin, bellmouth, fixed screw.
Described quick change mold insert one end offers screw holddown groove, and the other end offers the hole of fixed locating stud, and its middle part offers bellmouth.
The beneficial effects of the utility model:
It is simple in structure, simple to operation for the utility model, and convenient for maintaining, reduces costs, and enhances productivity, and reduces pincers worker labour intensity.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is fixedly insert structure schematic diagram of the utility model.
Fig. 3 is the utility model quick change insert structure schematic diagram.
The specific embodiment
Referring to accompanying drawing, a kind of porous punching quick change lower die structure, comprise die shoe 10, described die shoe 10 two bottom sides have been screwed respectively bottom seat pad 11, die shoe 10 both sides, upper surface are fixed with respectively outer guiding post 8, the upper surface of die shoe 10 is provided with lower bolster 9, lower bolster 9 both sides, upper end are provided with lower bolster 2, described in two, lower bolster 2 wherein offers holddown groove 13 in lower bolster 2 upper surfaces of one end, lower bolster 2 passes holddown groove 13 and lower bolster 9 by screw 1, die shoe 10 connects, between two lower bolsters 2, be provided with fixedly mold insert 5, fixedly mold insert 5 one end, upper surface are fixed with quick change mold insert 3 by screw 6, fixedly mold insert 5, lower bolster 9, die shoe 10 the same side, one end vertical directions offer and the hole 14 of knocking bar 12 respective shapes and size, lower bolster 2, lower bolster 9, other end the same side vertical direction of die shoe 10 offers the hole 15 of alignment pin 7 respective shapes and size, in hole 15, be fixed with alignment pin 7.
Described fixedly mold insert 5 is shaped as cuboid, adopt Cr12 material to make, fixedly mold insert 5 upper surface, one end inboard, upright directions offer screw 16, and fixedly mold insert 5 bottoms offer the screw 19 of corresponding hole 17 of knocking the hole 14 of bar, corresponding alignment pin, bellmouth 18, fixed screw.
Described quick change mold insert 3 one end offer screw holddown groove 20, and the other end offers the hole 21 of fixed locating stud, and its middle part offers bellmouth 22.
Counterdie mold insert is divided into fixedly mold insert 5, quick change mold insert 3, wherein fixedly mold insert 5 adopts Cr12 material, all material spilling holes get out with CNC, without carrying out line, cut processing, quick change mold insert 3 adopts customized white steel of returning or other good high hard material of heat treatment, directly line cuts, and because thickness of slab is thinner, line cuts and can save a greater part of time.During assembling, first fixing mold insert 5 is locked on lower bolster 9, and then quick change mold insert 3 is locked in fixedly on mold insert 5.During maintenance, the screw 6 of first dismantling, then ejects quick change mold insert 3 with knocking bar 12.Again change a new mold insert, positioned in alignment pin 4, packs into fixedly in mold insert 5, lock screw 5, and maintenance completes.
Although illustrated and described embodiment of the present utility model, for a person skilled in the art, be appreciated that in the situation that not departing from principle of the present utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is limited by claims and equivalent thereof.
