Abstract

The present invention relates to a method for amplifying design data of a pair of soles, which comprises the following procedures: A. data to be amplified of a pair of soles is prepared; B. the amplifying data is set; data of a reference code dimension, etc. is set, and at least one lock-on boundary is set; C. the amplifying is calculated; a requisite proportion value is found and converted according to relevant setting in the procedure B, and the amplifying data is divided into a natural amplifying region, a buffering region and a locking region according to the lock-on boundary; inequality proportion zooming calculation is gradually carried out to positions of each controlling point of each defined curved face of data in the buffering region; D. the data is stored in a disk, and the data which is amplified and calculated is stored in the disk for reserve.

Description

The level of sole design data is put method

Technical field

The present invention relates to the manufacturing technology of sole, carry out according to demand about a kind of geometry data particularly that selectivity is amplified or the level of the sole design data of dwindling is put method sole.

Background technology

Comfortableness when asking wear or functional now has designs such as adding air cushion, oil bag in sole, and making the user more comfortable when the wear, and elasticity is better.

In the process of exploitation sole mould, general mode is to set up standard-sized sole CAD (3D CAD) model earlier at present, use CAD (3D CAD) model of this standard size to amplify again and dwindle, use CAD (3D CAD) model of setting up various sizes.

Yet, aforementioned known CAD (3D CAD) model is amplified dwindled in the mode, owing to be that the equal proportion amplification is dwindled, and air cushion, oil bag equidimension is but fixed, therefore after sole being amplified or dwindles, sole is kept for air cushion, the space of oil bag is also amplified synchronously or is dwindled, cause full-sized air cushion, the oil bag can't be suitable insert sole, only when amplifying, this space is locked, so that after amplification, still can keep the size in this space, make air cushion, the oil bag can be inserted suitably, yet existing CAD (CAD) system can't realize local locks with respect.Known settling mode has two:

One, the air cushion of the multiple size of exploitation or oil bag: this can increase design, manufacturing and stock's cost, is not a good settling mode.

Two, with the design at the bottom of artificial each shoe sizes of modification in addition, make its air cushion that goes for single size or oil bag etc. add thing.Yet this can increase the cost of personnel, time equally, and differs with manual amendment's product quality, and personnel's educational training has also been increased cost.

Therefore, above-mentioned dual mode is not best solution.

Summary of the invention

Main purpose of the present invention is to provide a kind of level of sole design data to put method, it can optionally amplify or dwindle the geometry data of sole, effectively improve sole after amplification is dwindled, add the problem that thing structurally can't match with air cushion or other.

Secondary objective of the present invention is to provide a kind of level of sole design data to put method, and it can effectively reduce cost, but also steady production quality.

Description of drawings

Fig. 1 is the block diagram of a preferred embodiment of the present invention;

Fig. 2 is that the level of a preferred embodiment of the present invention is put position description figure.

The specific embodiment

In order to describe technical characterstic of the present invention place in detail, now lift a preferred embodiment and conjunction with figs. and be described as follows:

As shown in Figure 1, put method, mainly have the following step for the level of a kind of sole design data that a preferred embodiment of the present invention provided:

A, the level for the treatment of of purchasing sole are put data: how much data of the sole of first preparation standard size are as how much data of benchmark sole, the data that how much data of this benchmark sole produce for other CAD (CAD) system, or be how much data of a CAD that prestores (CAD), comprise geometric datas such as sole three-dimensional (3D) curved surface data, curve data and point data, and comprise most control points of definition curved surface or curve, be used for level and put calculating, level put calculate be meant with the standard size be the predetermined ratio that benchmark was carried out amplification, dwindle calculating.

B, level put table and level is put data setting: the data such as footwear sign indicating number that set each axial residual quantity between reference number size, each yard and reference number, will produce, and set the buffering area width, and set at least one lock-on boundary.

C, level are put calculating: look for or be converted into needed ratio value according to the related setting among the step B; To treat that the level data of putting distinguishes according to the lock-on boundary, the side in the lock-on boundary is the lock room, is buffering area in the preset width of lock-on boundary opposite side, puts the district for size fractions of raw coal outside buffering area.Wherein, putting district's data for size fractions of raw coal is to amplify or dwindle in the mode of fixed proportion, then not amplifying or dwindle calculating for the lock room data, then is that the position at each control point of each curved surface of definition in this district is carried out the calculating of inequality proportion convergent-divergent one by one for the buffering area data.

D, data deposit: the data deposit that level is put after the calculating is standby.

The above-mentioned level method of putting is for how much data of sole optionally being amplified or dwindling, when being benchmark with benchmark size #9, when wanting level to put size to #15, ratio value after it converts is X:1.111, Y:1.171, Z:1.087, above-mentioned X, Y, the ratio value when Z axis scale value is the equal proportion convergent-divergent, if when putting, then need to do a computing in addition according to this value with non-geometric ratio level.As shown in Figure 2, level with the Z axle is put and is calculated as example, the lock-on boundary is wire, it is a Z shaft lock alignment 41 (being arranged in the figure sole position), level is put data based Z shaft lock alignment 41 and is as the criterion, what be positioned at Z shaft lock alignment 41 belows is height lock room 31, and the altitude range that is positioned at Z shaft lock alignment 41 top 5mm is a buffering area 21, and the part that is higher than buffering area 21 is size fractions of raw coal and puts district 11.Wherein, size fractions of raw coal is put district 11 and is the equal proportion convergent-divergent, the Z axle magnification ratio 1.087 of #15 is all multiply by at each control point when amplifying, its inside, height lock room 31 then will not be amplified, then the amplification of inequality proportion being carried out at each control point of definition curved surface in buffering area 21, is example with three control points in the present embodiment:

Control point one is in the position of buffering area 75%, and then ratio is 1+0.087 * 0.75=1.0653;

Control point two is in the position of buffering area 50%, and then ratio is 1+0.087 * 0.5=1.0435;

Control point three is in the position of buffering area 25%, and then ratio is 1+0.087 * 0.25=1.0218;

From the above, amplification mode in buffering area 21 is not to carry out convergent-divergent with 1.087 equal proportion, but decide its ratio with its distance with height lock room 31, it is not the equal proportion convergent-divergent, can meet when making the demand that the binding face for the sole edge amplifies like this, also can meet sole accordance to air cushion or oil bag when amplifying size, and this method can be applicable in the design of carrying out with computer software, and then avoid manual amendment's problem, has effect easily and fast simultaneously, more can reduce production costs the steady production quality.

Aforesaid lock-on boundary is to be example with the wire, but technology of the present invention is not limited in this, the lock-on boundary also can a curved surface as the border, this equally also is a technology of the present invention.
