Abstract
The invention discloses a die stroke design and check method. For stroke design, the steps include defining data, setting a die stroke value set and a die closing height value set, restricting the defined data, determining a moving mode of a lift plate. For stroke check, the steps include inputting the defined data into an EXCELL sheet, setting an equation in a cell X and Y, judging whether or not the defined data are abnormal, if yes, automatically filling the cell X and Y in an amorality color for warning, defining the moving mode of the lift plate with a cell Z, setting a scroll-down option including multiple modes in the cell Z for selection, and checking the data of the steps above.
Description
Technical field
The present invention relates to technical field of mold, particularly a kind of mold stroke design and inspection method thereof.
Background technology
The progressive die, refers to forcing press in a punching stroke, adopts banded punching press raw material, a secondary mould completes with several different station the cold stamping punch die of multi-step forming processes simultaneously, the every punching press of mould completes once, and material strip fixed-distance moving once, completes to product.
For in continuous die design, designer, because lacking experience, after upper and lower mould stroke reasonable set, does not find that mold stroke can not meet production or Mould Code mould needs of problems.So the travel settings up and down of carrying out mould by experience can bring very large unstability, easily very large damage even scrap mould is caused to mould.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, provides a kind of mold stroke to design and inspection method.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of mold stroke design and inspection method thereof, wherein, stroke designs: 1) define data, described mold stroke numerical value group comprises ram travel A, from top dead-centre to bottom dead centre, feeding area E is comprised successively in described ram travel A, when material strip floats, stripper plate leaves the distance D of material strip, material lift plate stroke C and stripper plate stroke B, described die shut height numerical value group comprises die shut height S, feed level F and die shut height, described die shut height S comprises minimum of a value Smin and maximum Smax, 2) described B+ C+D < A and Smax-B-C-10MM >=die shut height >=Smin+20MM is limited, 3) material lift plate move mode is determined,
Inspection method: definition data field a) is set in Microsoft Excel, comprises all data in above-mentioned steps 1; B) a cell X is got, in this cell X, arrange formula is=B+ C+D, and an IF function is set in this cell X, an IF function is be judged as exception when the numerical value of this cell X is greater than A, and is that abnormal color is with warning by cell X automatic filling; C) get another cell Y and be defined as die shut height, and the 2nd IF function is set in this cell Y, 2nd IF function is that what make not meet Smax-B-C-10MM >=die shut height >=Smin+20MM condition is all abnormal, and is that abnormal color is with warning by cell Y automatic filling; D) get a cell Z and be defined as material lift plate move mode, and in cell Z, arrange the drop-down option comprising various ways for you to choose.
In technique scheme, described material lift plate move mode comprises: mode one, and described material lift plate stroke C is at below F; Mode two, described material lift plate stroke C is middle separated time with feed level F; Mode three, as material lift plate stroke C≤30MM, described material lift plate stroke C is middle separated time with feed level F, as described material lift plate stroke C > 30MM, described material lift plate stroke C with feed level F for line of demarcation, be positioned at 2/3 stroke that more than feed level F is material lift plate stroke C, be positioned at 1/3 stroke of below feed level F for material lift plate stroke C.
The various heavy losses the invention has the beneficial effects as follows: by the design data of mould is organized in EXCEL software, and arrange the exception of design data is warned, reduce the dependence to experience with this, reduce cost of labor, preventing because correlation experience causes.
Accompanying drawing explanation
Fig. 1 is mould clock figure of the present invention;
Fig. 2 is that mould of the present invention closes schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1, 2, a kind of mold stroke design and inspection method thereof, comprise the design of mold stroke and the inspection method to the trip data.By empirical data, and graphically, the situation of assuming as a matter of course is avoided to cause the generation of heavy losses.
Wherein, stroke designs: 1) define data, mold stroke numerical value group comprises ram travel A, from top dead-centre to bottom dead centre, comprise feeding area E successively in described ram travel A, material strip when floating stripper plate leave distance D, material lift plate stroke C and the stripper plate stroke B of material strip, described die shut height numerical value group comprises die shut height S, feed level F and die shut height, and described die shut height S comprises minimum of a value Smin and maximum Smax; 2) described B+ C+D < A and Smax-B-C-10MM >=die shut height >=Smin+20MM is limited; 3) material lift plate move mode is determined.Wherein, ram travel A refer to slide block from top dead-centre to bottom dead centre the distance of process.。Material lift plate stroke C refers to the material lift plate of support material strip from matched moulds to the displacement that matched moulds is complete produced.Feeding area E refers to that material strip does not all tangle up and down, normally can do the lift area of feeding campaign, and this region can affect time morning and evening of feeding, namely can affect production efficiency.Mould clock run-length data and closed data are closed schematic diagram by mould clock figure and mould show, as shown in Figure 1, 2, intuitively simple, as long as user knows proportionate relationship and the position relationship of mold stroke data at a glance, so that check the setting of mold stroke altitude information, reduce the possibility of makeing mistakes.
Inspection method: definition data field a) is set in Microsoft Excel, comprises all data in above-mentioned steps 1; B) a cell X is got, in this cell X, arrange formula is=B+ C+D, and an IF function is set in this cell X, an IF function is be judged as exception when the numerical value of this cell X is greater than A, and is that abnormal color is with warning by cell X automatic filling; C) get another cell Y and be defined as die shut height, and the 2nd IF function is set in this cell Y, 2nd IF function is that what make not meet Smax-B-C-10MM >=die shut height >=Smin+20MM condition is all abnormal, and is that abnormal color is with warning by cell Y automatic filling; Wherein, die shut height >=Smin+20MM is the minimization principle as die shut height, and meeting under the condition that mould normally produces, secondary principle is conducive to reducing mold height, reduces the cost of material; D) get a cell Z and be defined as material lift plate move mode, and in cell Z, arrange the drop-down option comprising various ways for you to choose, just directly can judge that whether selected mode is corresponding with the stroke C of material lift plate, prevents design from makeing mistakes when inspection; E) carry out inspection to above each step data to examine.
Wherein, described material lift plate move mode comprises: mode one, and described material lift plate stroke C is at below F; Mode two, described material lift plate stroke C is middle separated time with feed level F; Mode three, as material lift plate stroke C≤30MM, described material lift plate stroke C is middle separated time with feed level F, as described material lift plate stroke C > 30MM, described material lift plate stroke C with feed level F for line of demarcation, be positioned at 2/3 stroke that more than feed level F is material lift plate stroke C, be positioned at 1/3 stroke of below feed level F for material lift plate stroke C.
Above embodiment is merely illustrative and not limiting to the invention, therefore all equivalences done according to the method described in patent claim of the present invention change or modify, and are included in patent claim of the present invention.
