Description

Technical Field

[0001] The present invention relates to the field of umbrella rib mold structures, and particularly to a mold structure for automatically positioning and fitting umbrella ribs. Background Art

[0002] An umbrella, as an essential daily necessity for sunshading and rain shielding, is used very frequently in daily life. The structure of an umbrella mainly includes an umbrella handle, several groups of umbrella ribs connected to the umbrella handle, and an umbrella surface supported by the umbrella ribs. The existing umbrella ribs are mainly formed by riveting multiple umbrella rib segments together. However, the existing riveting technology for umbrella ribs is still relatively primitive. It mainly relies on manual operation to align the riveting holes of two umbrella rib segments, then place them into a riveting machine for riveting, and then take out the next umbrella rib segment to continue aligning the riveting holes for riveting. This method of relying on manual alignment of the riveting holes of umbrella rib segments can only align one pair of riveting holes at a time. Therefore, only one rivet can be riveted each time, resulting in a very slow speed of umbrella rib riveting; during the operation, the worker's fingers are often at risk of being injured by the riveting machine, and manual operation is prone to errors, producing defective products and reducing the riveting quality of the umbrella ribs.

[0003] In view of this, the applicant of the present invention conducts in-depth research on the above problems, and thus this case is generated. Summary of the Invention

[0030] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail through specific embodiments below.

[0031] As Figure 3-7 shown, a die structure for automatically positioning and fitting umbrella ribs, wherein, it includes a plurality of positioning modules 1, and a positioning groove 2 for fixing umbrella rib segments is provided on the positioning module 1.

[0032] After adopting the above - mentioned structure, the umbrella ribs are placed in the corresponding positioning grooves 2 for positioning, and then the positioning modules 1 are relatively combined, so that the umbrella rib segments in the positioning grooves 2 are automatically inserted into each other. Then, they are sent into a riveting machine for riveting. The lower die of the riveting machine contacts the umbrella rib segments through the riveting through - holes 3 and rivets the umbrella rib segments together.

[0033] Compared with the prior art, the beneficial effects are that the present invention can realize the automatic fitting of umbrella rib segments, improve the riveting efficiency of umbrella ribs, without the need for a large amount of manpower, save production costs, and at the same time use a die to accurately position the umbrella rib segments, improving the quality of umbrella rib riveting.

[0034] Preferably, the number of the positioning modules 1 is at least two, and each positioning module 1 is provided with at least one positioning groove 2. As one embodiment of the present invention, the positioning module 1 is a first module 11 and a second module 12, which respectively position a first umbrella rib segment 41 and a second umbrella rib segment 42. The positioning grooves 2 are a first positioning groove 21 and a second positioning groove 22. The first positioning groove 21 is provided on the first module 11, and the second positioning groove 22 is provided on the second module 12. The first positioning groove 21 is used to accommodate the first umbrella rib segment 41, and the second positioning groove 22 is used to accommodate the second umbrella rib segment 42. The first positioning groove 21 and the second positioning groove 22 are communicated with each other so that when the modules are combined, the first umbrella rib segment 41 and the second umbrella rib segment 42 in the modules are inserted into each other at the communication part of the first positioning groove 21 and the second positioning groove 22.

[0035] Preferably, as Figure 1-2 shown, in the embodiment of the present invention, the first umbrella rib segment 41 has a clamping groove 414 for the second umbrella rib segment 42 to be inserted. Since the umbrella rib segments to be riveted together need to be first fitted together before riveting, the first positioning groove 21 and the second positioning groove 22 need to have different groove depths. In this way, there is a depth difference between the first positioning groove 21 and the second positioning groove 22, so that when the first module 11 and the second module 12 are fitted, the second riveting head can be inserted into the clamping groove 414 to form a state of being inserted into each other.

[0036] More preferably, the groove depth of the first positioning groove 21 is greater than that of the second positioning groove 22. When the first umbrella rib segment 41 and the second umbrella rib segment 42 are positioned and fitted, the second umbrella rib segment 42 can be inserted into the clamping groove 414 of the first umbrella rib segment 41 in alignment.

[0037] Preferably, the first module 11 has a first fitting surface 111 that fits with the second module 12. The first positioning groove 21 is provided on the upper surface of the first module 11, and the notch at one end of the first positioning groove 21 extends to the first fitting surface 111 to form a first opening 112. After adopting the above structure, the first umbrella rib segment 41 is provided with a first rod body 411 and a first riveting part 412 connected to each other, and a clamping groove 414 is formed by extending the first riveting part 412 along the length direction. The first riveting part 412 is provided with a first riveting hole 413. The first rod body 411 is embedded in the first positioning groove 21, and the first riveting part 412 faces the first fitting surface 111 and extends out from the first opening 112.

[0038] Preferably, the second module 12 has a second fitting surface 121 that fits with the first module 11. The second positioning groove 22 is provided on the upper surface of the second module 12. One end of the second positioning groove 22 extends to the second fitting surface 121 and forms a second opening 122. The second rib segment 42 is provided with a second rod body 421 and a second riveting portion 422. The second riveting portion 422 is provided with a second riveting hole 423. The second rod body 421 is embedded in the second positioning groove 22. The second riveting portion 422 faces the second fitting surface 121 and extends out from the second opening 122. The position of the second opening 122 corresponds to the position of the first opening 112 one by one. When the first module 11 and the second module 12 are fitted together, the first riveting portion 412 of the first rib segment 41 and the second riveting portion 422 of the second rib segment 42 can be fitted together, and the first riveting hole 413 and the second riveting hole 423 are aligned with each other, which is more accurate and efficient than manual alignment.

[0039] Preferably, a first through groove 31 that penetrates the first module 11 from top to bottom is provided directly below the first opening 112. A second through groove 32 that penetrates the second module 12 from top to bottom is provided directly below the second opening 122. The first through groove 31 and the second through groove 32 are correspondingly matched to form a riveting through hole 3. After adopting the above structure, the lower die of the riveting machine can enter the positioning module 1 from below the riveting through hole 3 respectively, and then contact and rivet with the rib segment.

[0040] Preferably, in addition to being placed in the positioning groove 2 manually, the rib segment can also be placed in the positioning groove 2 by being clamped by a manipulator. In order to provide a space for the manipulator, a first relief groove 113 is further provided on the first module 11, and a second relief groove 123 is further provided on the second module 12. The first relief groove 113 and the first positioning groove 21 are arranged alternately, and the second relief groove 123 and the second positioning groove 22 are arranged alternately.

[0041] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the present invention.
