Design Of Gourd Head Single Side Zipper Short Tube Men'S Boots

Gourd head, also known as the doll head, is a classic design of boot products, which requires double conversion and pick up.

The so-called double conversion take off method, that is, in the front and bottom to carry out the two conversion to take off, is the design of gourd head special pick up method.

1. finished product drawing

As shown in figure 5-2-10, the front part of the shoe is a whole block, which is equivalent to the hoist head of the tongue. It reaches two points or more than the E point.

The pulling force of the clippers can play an effective role in tightening the first turning around the V point, but for the second turning around the E point, there is something to be done, so it is necessary to do the two conversion.

For the first time, it is aimed at the lower part of the front Gang, and the second switch is aimed at the gourd head.

 

2. structure design drawing

As shown in Fig. 5-2-11, the height of the back tube is 160mm and the width of the cylinder is 140mm.

 

The reduction of the early gourd head is done by manual operation. The wider the head of the gourd is, the worse it is to restore. Therefore, the traditional width is narrower. The male boots take 20 to 24mrn and the female boots take 16 to 20mm.

With the appearance of the surface shaping machine, the width of the head of the gourd increases gradually, and even the boot of the half face is constantly helping.

No matter whether the gourd head is wide or narrow, the method of reduction is manual or machine.

First design the back frame and then design the front part.

The specific operation is as follows:

(1) make the middle line of the back line in the appropriate position near the last back curve to connect a straight line for the back midline. It is required that there is no gap between the straight line and the original back middle curve. It is also requested that the vertical line of the 07 point of the heart of the towing towel should be placed in the back midline of the straight line and on the back middle line of the curve.

(2) the way to take the changeover from the lower part of the front to the lower part of the front part is to change the seesaw method in the basic structure.

Take 0 points as the center of the circle, take the radius of 0'Ao as the arc, intercept the conversion length to A2 point, and make the H1O'H2.

And intercept the A2A2'length difference of 1 / 3 to the bottom of the front support.

(3) the head of the gourd is taken to change the vertical line of the back midline through the 0'point, and the position of the 2/3 is fixed to 0 points, and the 0 point is the center of the circle. The length E' of the gourd head is the arcs of the radius and intersects with the back midline at the Eo point, and the contour line after the pformation of the gourd head is designed through the E point.

After designing the contour line of the gourd head, the replica plate of the original shape of the gourd head should be first prepared and drawn along the straight back midline with the duplicate plate.

This is the same as using the replica board to describe the outline of the shoe.

The length of the pformed head is longer than the actual length of the gourd head, shorter than the length of the conversion, less than the 1/3 of the head length of the gourd head.

The 1 / 3 amount needs to be stretched through the bottom edge and the back side, so that the head of the gourd is bent on the last surface.

Remember the design of the cover shoe?

"One piece is on the top of the shoe and one is on the fence," the result is a difference of 1 / 3 in length.

The design of gourd head also keeps the length difference of 1/3.

In the use of leather materials with better elongation, there is no special requirement for cutting. However, when the material is not ideal, or when using artificial leather, pverse blanking should be used to ensure the effective operation of the drawing.

The design of other components is the same as that of high waist shoes.

The position of the zipper is taken at the middle point of the width of the inner opening, and the 1 / 2 position of the lower part is inclined forward.

Zipper has zipper tongue parts.

The cylinder mouth part of this picture is straight line outside, and the inside is higher than 2 3mm outside.

Some of the products in Taiwan are less expensive than those in the outside world, because the wearing parts are not seen when they are dressed.

Some foreign products are of the same height inside and outside. We can see that there is no hard rule on who is taller or lower.

The upper part of the back line should be 1.5 to 2mm.

When the upper part of the back pack is joined to the seam, taking into account the smooth connection, a technological quantity should be collected. When the upper part of the back pack is also taking the center line, it can not shrink.
