Problems solved by technology
In order to meet the requirements of the maximum stress, the width of the blanking can only be designed according to the maximum stress point, and the strength of many places is excessive, resulting in a large waste of materials, which is very uneconomical
Moreover, some positions are prone to breakage under special circumstances

Embodiment Construction
[0044] It should be noted that the "upper end" mentioned in the present invention refers to the end facing the direction of the umbrella rod, and the "lower end" refers to the end away from the direction of the umbrella rod. In the same way, "upward" refers to the direction toward the umbrella pole, and "downward" refers to the direction away from the umbrella pole. The so-called up and down only refers to their relative positions, which is convenient for description and is not particularly limited. Of course, "up" can also be defined as "left" and "down" can be defined as "right", which does not affect the structural relationship of the present invention.
[0045] refer to Figure 14-Figure 21 , a force-optimized third-speed umbrella rib of the folding umbrella of the present invention includes an umbrella rib body, the upper end of the body is provided with a first mounting hole 11 for connecting the upper plate 4, and the middle part is provided with a connecting four hole...

The invention discloses a stress-optimized three-gear umbrella rib of a folding umbrella. The umbrella rib comprises an umbrella rib body. The upper end of the body is provided with a first installation hole for being connected with an upper disc. The portion, close to the lower end, of the middle of the body is provided with a second installation hole for being connected with a four-gear umbrella rib. The lower end of the body is provided with a third installation hole for being connected with a small saddle. The body is formed by folding blank formed through stamping in half along the center line in the length direction. The stress-optimized three-gear umbrella rib is characterized in that the width of the portion, located on the second installation hole area, of the blank is largest, and the width of the other part is small. By changing the shape of the blank for manufacturing the three-gear umbrella rib, the main stress part is appropriately widened, and the sub stress part is appropriately narrowed, so that materials are saved, the overall stress capability of the three-gear umbrella rib is improved, and the fracture problem of the umbrella rib is greatly reduced; in addition, during stamping and discharging, the large end and the small end can be alternately arranged in a left-right mode, width complementing is achieved, and therefore materials can be greatly reduced.
Description
technical field [0001] The invention relates to umbrella parts, in particular to umbrella rib parts, in particular to a force-optimized three-speed umbrella rib of a folding umbrella and a processing method thereof. Background technique [0002] Conventional folding umbrellas have different structural forms such as three-fold umbrellas and five-fold umbrellas. like figure 1 As shown, a typical three-fold umbrella includes a handle 1, an umbrella stem 2, an umbrella stand 3, an upper plate 4, an umbrella surface 5 and a lower plate 6. The umbrella upper plate 4 and the handle 1 are respectively fixed and installed on the upper and lower ends of the umbrella pole 2, the lower plate 6 is sleeved on the umbrella pole 2, and can slide up and down along the umbrella pole 2. The upper edge of the upper plate 4 and the lower plate 6 are A group of grooves are evenly opened on the outer circumference. [0003] combine figure 2 , the umbrella frame 3 is composed of a group of bon...
