Abstract
The invention provides a kind of method of impulse- free robustness punching press, the second area of the drift pressing material band of diel（That is the position of product）The second area is moved downward, the corner of second area bottom will be formed the first fillet by pulling force, then drive the ejection part of diel to move upwards, ejection part ejects sagging second area upwards, the first area of the upper surface of second area by material strip（That is waste material）Pulling force will be formed one second fillet, form the first fillet and the second fillet by the flowing of metal, can effectively prevent that burr from occurring in the edge of product, particularly when product precision size degree require it is higher when, the demand in market can be met significantly.
Description
Technical field
The present invention relates to a kind of Sheet Metal Forming Technology, more particularly to a kind of method of impulse- free robustness punching press（Negative clearance punching press, half-dozen drift does not enter cavity plate, is then again clapped product in feed back band with mold insert of clapping）.
Background technology
Decompressor currently used in the market, it is main to include on one module and once module, drift and guiding pin etc. are provided with upper module, when using, material strip is placed on lower module, then drive the drift to move downward, material strip gone out to a through hole or blanking by the way of blanking, but the through hole that is formed of the mode of this blanking and outline edge have one side that many sides thorns occur（Burr）, cause product bad, for above-mentioned situation, the one side pierced with side is carried out clapping the processing of C angles, pierced side using compression by also producer（Burr）Extruding, can this extruding certainly will will cause through hole inwall formation projection, it is difficult to reach the requirement of high precision, especially when the size for the product being related to is smaller, size requirement above be even more be difficult to it is eligible, this way be difficult make precision product, it is difficult to meet the demand in market.
The content of the invention
It is an object of the invention to the defect for overcoming prior art, there is provided a kind of method of automation, high-accuracy impulse- free robustness punching press.
What the present invention was realized in：A kind of method of impulse- free robustness punching press, it includes：

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
Such as Fig. 1 to Fig. 6, the embodiment of the present invention provides a kind of method of impulse- free robustness punching press, and it comprises the following steps.
The first step, one diel is provided, it, which has to be provided with drift, the lower module to be provided with module and once module, the upper module on one, pushes up bottom, clap mold insert and cavity plate, the drift is made up of nonferrous materials, it can move up and down and move with mould, the top bottom is in tabular, and the mold insert of clapping also is in tabular, the ejection part can also move up and down, and the cavity plate is to accommodate the sheet material after punching press is sunk.
There is provided a material strip 1 for second step（Sheet material）, below with sheet material（Material strip）Exemplified by, the sheet material 1 is metal and other hard plate materials, first area 11 and the second area 12 abutted with the first area 11 are provided with the sheet material, the first area and the second area are with the presence of a virtual edge of a knife, the first area 11 and the second area 12 are arranged alternately, sheet material is active on the lower module, and complete to work continuously, the lower surface of first area 11 is set to be connected to the top bottom, and top bottom is higher than lower module, that is top bottom is higher by lower 0.01~0.02mm of module upper surface, the top bottom is directly connected on the second area 12, prevent the stress of second area 12 and overall deformation.
3rd step, the drift is driven to move downward, drift extrudes second area 12, the lower surface of drift and the upper surface sizableness of second area 12, move downward the second area 12, a part of material of the second area 12 enters in the cavity plate, and the distance that the second area 12 declines is the 60%~90% of the thickness of material strip.The corner of the bottom of second area 12 will be forced into one first fillet 124, first fillet 124 sets to the concave, in smooth arc-shaped, continue to drive drift to move downward, until the upper surface of second area 12 is higher than the lower surface of the first area 11 in thickness 10%~40% of material strip, and the upper surface of second area 12 is less than the upper surface of the first area 11, now first area 11 and second area 12 are additionally attached to together, and upper module drift is retracted.
4th step, the material strip is driven to move downward, the mold insert of clapping ejects sagging second area 12 upwards, the upper surface of the second area 12 is set to be higher than the upper surface of the first area 11, the upper surface of the second area 12 will be formed one second fillet 125 by the stretching of first area 11, and the second fillet 125 sets to the concave, in smooth arc-shaped, material strip is moved up and exits mold insert of clapping in diel uphill process, and product is remained secured in material strip, and then can obtain sheet material 1.
Further, the drift falls the centre of form in the projection of vertical direction and overlapped with the cavity plate centre of form, it is easy to drift to depress second area 12, and also to ensure that the part second area 12 pushed up on bottom is connected on the bottom of top, after the formation of second fillet 125, there is a strip gap in the side of first area 11 described in the side of the second area 12（Produce large and small face）.
After the 4th step, the product that the second area 12 is formed after punching press, the second area 12 includes a main part 121（Facet）, the side of main part 121 has a protuberance 122（Big face）, the upper surface of the protuberance 122 and the upper surface flush of the main part 121, the periphery of the protuberance 122 has one second fillet 125, the upper surface of second fillet 125 from the protuberance 122 is extended downwardly, and intersect at the side of the protuberance 122, extend a base plate 123 under the bottom surface of the main part 121, the outward flange of the base plate 123 and the outward flange of the main part 121 are connected by the first fillet 124, one first fillet 124 and the second fillet 125 are formed by the flowing of metal, particularly when the precision size degree of product requires higher, it can effectively prevent that burr from occurring in the edge of product, certainly, sheet material in the present invention is used primarily on automatic punching machine（It can also use on one-shot）, it is easy to large-scale batch production, also allows for the control of size.Relative to conventional design, that is, process is saved, the technique for also reducing subsequent treatment, without using other handling process again, direct punching press can just produce carrot-free product, the demand of production is met significantly, particularly the product of high precision when, its effect is more notable.
It in another the design, can also will be changed over above and below upper module and lower module, carry out stamping process, its direction moved is also just reverse, but its principle is identical, just not burdensome narration herein, its result can also obtain identical product, should also belong within the scope of the present invention.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, within the spirit and principles of the invention, any modifications, equivalent substitutions and improvements made etc. should be included within the scope of the present invention.
