Description
Technical field
The present invention relates to a kind of punching die, more particularly, to a kind of locking board punching die.
Background technology
The existing D-117 locking boards punching die of company, its structure as depicted in figs. 1 and 2, including upper die component and lower mould
Component, wherein, upper die component includes upper bolster 1, upper padding plate 2 and upper solid plate 3, and upper padding plate 2 and upper solid plate 3 are set successively from top to bottom
Put below upper bolster 1, be provided with drift 9 directed downwardly in upper solid plate 3, drift 9 is provided with mold notch, and the material of mold notch is
CR12MOV, lower mold assemblies include die shoe 8, and the lower template 6 and lower bolster being successively set on from top to bottom on die shoe 8
7, lower template 6 is interior to enter block 10 with lower mould of the correspondence position of drift 9 provided with a length of 33.3mm, and the upper solid lower section of plate 3, which is provided with, takes off material
Plate 5, stripper plate 5 is connected with the gim peg being arranged on upper solid plate 3, provided with the de- material of auxiliary between stripper plate 5 and upper solid plate 3
Excellent power glue 4.During work, workpiece 11 is fixedly installed in lower template 6, and drift 9 is punched out to workpiece 11.
During using above-mentioned D-117 locking boards punching die to workpiece punching, lower mould enters block and is very easy to rupture, for every eight hours
Often set perforating die will change lower mould and enter block 2-3 parts, be wasted in that repair a die above will be 2-3 hour daily, some made products mao
Thorn it is very big, it is necessary to polish could shipment, so time-consuming and laborious, product quality cannot be guaranteed again, meanwhile, excellent power glue auxiliary takes off
Flitch Yin Qituo material power is uneven, easily produces the phenomenon that gets stuck.In addition, using D-117 locking boards punching die to workpiece punching
When, the distance in the hole gone out to workpiece only has 1.4mm, and workpiece material thickness is 4.0mm, beyond the distance in hole in Sheet Metal Forming Technology to side
The thick requirement of minimum 1.5 material, has a strong impact on the volume production of product.
Chinese patent 201310749772.0 discloses the locking board punching die that a kind of thickness is more than more than 3.5mm, bag
The upper die component and lower mold assemblies matched is included, wherein upper die component includes upper padding plate, upper mounted plate, in addition to Type B drift, Gu
Determine bolt, described Type B drift is fixed on upper mounted plate by fixing bolt.The B of the locking board punching die of the patent
Lower mould below type drift enters block and is easily damaged, and the phenomenon that easily got stuck during de- material, so as to seriously reduce production efficiency.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of production efficiency is high
Locking board punching die.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of locking board punching die, is included on the upper die component and lower mold assemblies of interconnection, described upper die component

Mould enters block, treats that punch workpiece is fixedly installed on lower mold assemblies, and stripper plate, described de- material are provided with below described upper die component
Nitrogen spring provided with the de- material of auxiliary between plate and upper die component, described lower mould, which enters, is provided with connected lower die-cushion below block
Block；During work, treat that punch workpiece is fixedly installed on lower mold assemblies, fixedly locked upper die component and lower mold assemblies, workpiece pressing,
The downward punching press of drift is punched out to workpiece, after the completion of punching, and in the presence of nitrogen spring, stripper plate is separated with workpiece, complete
Into de- material.
Described upper die component includes upper bolster, upper padding plate and upper solid plate, and described upper padding plate and upper solid plate are from top to bottom
It is successively set on below upper bolster, described upper solid plate is provided with drift, upper solid plate two ends are to having bolt structure, the screw
Structure extends through stripper plate two ends, and connects lower mold assemblies, and described stripper plate is provided with the drift moved up and down for drift
Hole, nitrogen spring is connected between described stripper plate and upper bolster, compared to excellent power glue, and nitrogen spring takes off material power uniformly,
Seldom occur not take off material, get stuck phenomenon.
Described lower mold assemblies include the die shoe, lower bolster and lower template for stacking setting successively from top to bottom, the lower mould
Plate is sequentially provided with lower mould in the correspondence position of drift and enters block and lower die-cushion block from top to bottom, and the two ends of described lower template are set respectively
There is the screw mouthful matched with bolt structure, enter the height of block, and lower die-cushion block is set below by shortening lower mould so that under
The intensity that mould enters block is greatly enhanced, and the lower mould occurred high pressure when mold notch is to workpiece punching enters block, and to stay phenomenon big
It is big to reduce.
Described upper bolster and the two ends correspondence position of die shoe are respectively equipped with connecting hole, by matching with the connecting hole
Connecting rod upper bolster and die shoe are connected.
Described lower template is provided with the positioning hole that multiple auxiliary work-pieces are positioned.
Described positioning hole is provided with four, and four positioning holes are square to be set.
The material of described mold notch is SKH51, and SKH51 is tungstenic high-speed tool steel, and mold notch has high abrasion
Property, high compressive strength, harden after high case hardness, excellent overall quenching degree, good surface treatment processability and excellent
Anti-temper softening, it is good to the processing effect of workpiece, be not likely to produce burr and the phenomenon such as weigh wounded, greatly reduce lower mould and enter block etc.
The generation of edge of a knife fracture phenomena.
Compared with prior art, the present invention has advantages below：
(1) save the operating time, improve production efficiency：The present invention by nitrogen spring by replacing excellent power glue, so as to reduce
Material, the generation for the phenomenon that gets stuck are not taken off, enters block and the below lower die-cushion block of setting by shortening lower mould, the lower mould of increase enters bulk strength,
Reduction stays phenomenon, so that repairing a die daily 2~3 hours of old mould the time, is reduced to 2~3 talentes of every production and repaiies 1 mould
Tool, substantially increases production efficiency；
(2) product quality is obviously improved：Lower template is provided with positioning hole, auxiliary work-piece positioning, so that effectively guarantee pair
The precision of workpiece punching, it is ensured that the punching requirement to workpiece, the Work-piece burr phenomenon after punching is significantly reduced, and product, which is weighed wounded, to be subtracted
It is few；
(3) cost is low：The mold repair expense of the present invention greatly reduces, and maintenance die master worker's workload greatly reduces, dimension
Repair personnel and reduce to 4 by 5.
