Design Of Inner Ear Type Shallow Enclosure Shoes

1. finished product drawing

As shown in figure 2-2-1, if you do not look at the shallow section, this is a short ear type inner ear shoe.

With the shallow section, it will form the inner ear type shallow enclosure shoes.

 

On the shoe cover, there is a decorative line of cars, and a line of traces is arranged to form rhythmic rhythms.

The distance between false lines is controlled at about lOmm.

In the early design, the positioning and picking method was adopted, so that although the position of the shoe ears and the round bars could be designed, the technological sedan was not easy to handle, so now it was replaced by two lines.

2. structure design drawing

The structure design of inner ear type shallow enclosure shoes is shown in figure 2-2-2.

 

(1) first design the rear part of the shoe ears, because the shoe covers and the surround strips are painted with the replica board. First, confirm the back helps to find the connecting positions of the shoe covers and the surround strips.

The length of the ear is taken at 1 / 2VE, making the shoe eye position, the shoe ear and the shoe contour, and also making the rear package and the contour line.

Under the O point, the position of lOmm is connected to the straight line of the girth, and then the position and the position are reached.

(2) design the shoe cover and the fence strip, use the two arc intersection point to find the J'point, connect the back midline J'V.

From the point of view, draw the outline of the shoe cover with the copy board on the straight line in the back line, then connect it to the straight line of the surround strip, and the termination point is O'.

From the point of J', draw the outer outline of the fence with the replica board on the back curve and follow the O' point.

Make the difference between the inside and outside of the shoe cover and the enclosure.

The front line of the fence is connected with the AJ'line as the center line of the girth.

At this time it will be found that the contour of the front end of the bar is not smooth and can be corrected along the arc line of the bar as the vertical line of the middle line, and the amount of the loss is supplemented under the bandage of the bottom.

As shown in the shadow.

Finally, the contour of the bottom rib and the difference between inside and outside are designed.

The template for making shallow shoe is the same as that in front.
