Design Of Inner Ear Shoes -- Structural Design Of Women'S Two Head Shoes

Draw a half panel outline, connect 4 basic control lines, and make the natural angle zvoV7 with compasses.

Connect V point and J point to a straight line.

The A point of the bottom port is connected by arc to the back midline, and the intersection point is AO point.

A.

The V line is the front line.

The length of the front wings is at the middle point of FP near Fi.

From the front V'point, make the vertical line of the front midline, then draw a door outline along the vertical line to F1 point.

The width of women's shoes should not be too big, and the lines of both wings should be stretched.

In order to make the contour of the mouth door reasonable, the vertical line of the back midline of the back line is then passed through the V point, and the position of the contour of the mouth door after the intersection point of the two vertical lines is controlled.

To make the contour of the mouth smooth, smooth and stretches, it has a feminine soft form.

From A to V to F1 to A.

The closed curve is the contour of the front.

The design of the rear side is shown in figure 1-2-6.

Cross the vertical line of the front part of the bottom port and cross it with the OQ line, then decrease the 2mm position P 'point, connect the P'Q line as the shoe auxiliary line.

Then draw the outline of shoe ears and shoes by V, E, P, and Q.

Pay attention to the curve changes of shoe ears, the curve changes of the shoes should be consistent with the contour style of the shoe door.

The rear arc QB remains unchanged.

In the use of leather materials, if the rear arc is added to the seam, the upper becomes longer.

If you do not add the amount of sewing, although the seam will be reduced by about 2mm after the seam, it will be stretched when it is stretched, just to restore the selected design point.

If using synthetic leather and other materials, due to the low strength of the parts, the 3mm joint should be added and stitched on the 3mm line.

At the front end of the shoe ear, follow the vertical line passing through the Y point, and connect it with the arc to pick up the corner, and gradually intersect with the front contour line.

The intersection point of the two arcs is determined by 0 "points, and VO'V" is the positioning angle.

It is not deliberate to find the O point of the center. The location of the center is on the break line, and the two arcs of the front and rear sides are intersected with the O 'point, so that the contour of the template can be smoothly and without carving.

There are shoe eye positions and false lines on the back.

A parallel VE eye line is placed behind the middle line 13mm of the shoe ear. Then 5 equal parts are taken in the range of the ear length, and 4 eye positions are identified.

The position of the 12mm at the rear end of the eye line begins, and an arc is positioned at the middle point of the door, which is designated as the location of the dummy line.

The design of tongue and safety leather is shown in figure 1-2-7

The design of tongue and safety leather is more standard.

Taking the length of the shoe ear (VE) as the reference length, the front pressure stubble is 10 to 12mm, and the rear end is increased by 6 to 7mm.

The backend width is taken to the pseudo line position (25mm), and the front end width is less than the rear end 5mm.

(20mm).

First connect to trapezoidal shape, then connect the back end to a circular arc angle, and make a 30 degree inclination angle at the front of the stubble position as a mark for processing.

The width of the cover is 30mm and 20mm respectively.

During processing, take a piece of leather with the right length and width to pass through, then sew it on several pairs of upper shoes, and then sew one end and then cut it down and sew second pieces.

But when drawing the structural design, it is a rectangle to indicate a safety leather part.

The insurance cover for women's shoes is 20mmX18mm.

After the design of the front, back, tongue, and insurance skin, the structural design plan has been completed.

In order to prepare the template for supporting parts, it is necessary to add and stretch the bottom port and distinguish the inside and outside arms.

Although the thickness of the bottom can be accurately measured, the thickness and elongation of the material can not be unified, so it is better to adopt the "trial" method.

Men's shoes select a set of data of 14mm - 15mm '16mm 17mm. Women's shoes choose a set of data of 13mm 14mm, 15mm, 16mm. First, put out the amount of bandage and wait until the test is done, then determine the final amount of the bandage according to the needs. See Fig. 1-2-8.

The difference between the inside and outside of the bottom is based on the comparison between the original model and the last one, and there is no uniform provision.

However, there are rules to follow: in the AH section of the front part of the front part, about 2/3, the Huai River generally falls into 2 ~ 3mm; at the HF section of the bottom of the Chinese Gang, there is an increase in the number of Li Huai.

At the bottom of the PB section, the inside and outside are basically the same.

At the bottom of each part of the bar, the scissors are marked to make it easier to distinguish when opening.

Through the structural design of women's two quarter shoes, we can see that the analysis of finished products plays an important role in drawing structural drawings.

The finished product plan is the form representation of the shoe body. The structure diagram is the plane composition representation of the shoe parts, the more familiar the shape of the shoe is, the better the drawing effect is.
