In the figure: 11-leather ball sheet, 12-inverted triangular groove, 13-joint part, 14-mould, 15-inclined plane;
21-leather ball sheet, 22-inverted trapezoidal groove, 23-joint part, 24-mould and 25-inclined surface.
Detailed Description
The invention will be further described in detail by the following examples in conjunction with the following drawings:
soccer balls are regularly not longer than 70 cm, not shorter than 68 cm in circumference, and therefore have a diameter of 21.6561-22.293 cm. A soccer ball generally includes 20 regular hexagons and 12 regular pentagons having sides equal to those of the regular hexagons, with sides of about 4.576 centimeters.
The first embodiment is as follows:
referring to fig. 1-5, in the present embodiment, pentagonal leather ball pieces were prepared, which had a thickness of about 3 mm.
A manufacturing method of high-strength leather ball comprises the following steps:
s1, cutting the surface material to obtain a regular pentagonal leather ball piece 11 with the side length of 4.8 centimeters, wherein the cross section of the regular pentagonal leather ball piece is rectangular;
s2, processing an inverted triangle groove 12 along the peripheral edge of the leather ball sheet by a high frequency processing method or a hot plate processing method, wherein the inverted triangle groove is an isosceles triangle groove, the bottom edge is 1.2 mm, the height is 1.2 mm, one end of the inverted triangle groove close to the leather ball sheet is 1 mm away from the edge of the leather ball sheet, and meanwhile, in the high frequency processing method or the hot plate processing method, the leather ball sheet is contacted with a mould, a joint part 13 is formed on the inner wall surface of the inverted triangle groove under the action of heat energy, and the thickness of the joint part is about 0.5 mm;
and S3, pressing the leather ball sheet into the die 14 quickly, so that the joints 13 are jointed together along the central line of the inverted triangular groove, and under the action of the die, the bottom edge of the last leather ball sheet is an inclined plane 15 which is in arc transition with the bottom surface of the leather ball sheet and is in arc transition with the side surface of the leather ball sheet.
