Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to bushing processing, in particular to a continuous riveting tool for metal bushings of a seat frame. Background Art
[0002] In the early stage of seat frame development, before the formal tooling development is completed, the seat frame trial production and development process needs to frequently change the riveted metal bushings of different specifications for repeated debugging. The existing technology is that the technician holds the rivet rod with one hand and aligns it with the metal bushing hole that needs to be riveted, and keeps it perpendicular to the plane of the part. With the other hand, the technician uses an iron hammer to violently hit the rivet rod, so that after the underlying part is stressed, the hole wall expands outward, and then the flat surface of a heavier three-dimensional iron block is used to press the hole wall to complete the riveting of the parts.
[0003] This riveting process relies entirely on manual work. During the hammering process, if the hand holding the part is unstable or the hammering position is not on the center line of the rivet rod and there is a serious deviation, the rivet rod will "slip" or fly out. Regardless of whether it slips or flies out, the entire gravity of the hammer hitting down will fall on the hand holding the part, and the operator's hand holding the part will be injured. The way the human hand holds the rivet rod is extremely unstable. When the center of the rivet rod is not perpendicular to the plane of the part and there is a slight deviation, the left and right forces are uneven, the riveted flange will be uneven, and even the part will be scrapped.

[0004] The utility model aims to provide a continuous riveting tool for metal bushings of a seat frame, which is a riveting auxiliary tool with a wide range of uses, low cost, safety, quick replacement and stable quality, and provides hardware basic support for the early development and debugging of the seat frame.
[0005] To this end, the technical solution adopted by the utility model is: a continuous riveting tool for the metal bushing of a seat frame, comprising a base, a first punch rivet rod, a second punch rivet rod and a hammer, at least two hollow rivet rod columns of different specifications are welded on the base at intervals, each hollow rivet rod column is equipped with a first punch rivet rod and a second punch rivet rod, the wall thickness of the hollow rivet rod column should ensure that the flanged edge of the metal bushing can be fully supported from below; the punch of the first punch rivet rod can be partially inserted into the hollow rivet rod column for positioning, and the part of the punch of the first punch rivet rod remaining outside the hollow rivet rod column is used to expand the unflanged edge of the metal bushing outward at a certain oblique angle; the punch of the second punch rivet rod can be completely inserted into the hollow rivet rod column for positioning, and the root diameter of the punch of the second punch rivet rod is smaller than the rod diameter, so that the front end of the rod of the second punch rivet rod is used to expand the unflanged edge of the metal bushing outward into place to complete the riveting.
[0006] Further preferably, the number of the hollow rivet rod columns is five, and the inner diameters are 15-17 mm, 21-23 mm, 11-13 mm, 19-21 mm, and 17-19 mm, respectively, and the wall thicknesses corresponding to the inner diameters are 4 mm, 4 mm, 10 mm, 4 mm, and 4 mm.

[0009] More preferably, the height of the rivet rod columns is 48 mm, and the depth of the inner hollow portion is 46 mm.
[0010] The beneficial effects of the utility model are as follows: when the metal bushing is inserted into the bushing hole of the seat frame component and the flange is placed on the top of the hollow rivet rod column, the front end of the punch of the first rivet rod can first pass through the metal bushing from top to bottom and insert into the hollow rivet rod column, and when struck by a hammer, the rear end of the punch of the first rivet rod can open the unflanged edge of the metal bushing outward; when the first rivet rod is removed, the front end of the punch of the second rivet rod can pass through the metal bushing from top to bottom and insert into the hollow rivet rod column, and when struck by a hammer, the rear end of the punch of the first rivet rod can open the unflanged edge of the metal bushing outward; during the riveting process, the metal bushing will not slide left and right due to uneven force on the rivet rod, thereby affecting the quality of the flanging of the rivet rod. The metal bushing is evenly stressed and the flanging effect of the riveting is better. A plurality of rivet rod columns of different sizes and specifications are provided, which can be applicable to the riveting of metal bushings of different specifications, and have a wide range of uses, low cost, safety, quick replacement and stable quality.

At least two hollow rivet rod columns 2 of different specifications are welded on the base 1 at intervals. Each hollow rivet rod column 2 is equipped with a first punch rivet rod 3 and a second punch rivet rod 4. The wall thickness of the hollow rivet rod column 2 should ensure that the flanged edge 501 of the metal bushing 5 can be fully supported from below; the punch of the first punch rivet rod 3 can be partially inserted into the hollow rivet rod column 2 for positioning, and the part of the punch of the first punch rivet rod 3 remaining outside the hollow rivet rod column 2 is used to expand the unflanged edge 502 of the metal bushing 5 outward at a certain oblique angle; the punch of the second punch rivet rod 4 can be completely inserted into the hollow rivet rod column 2 for positioning, and the root diameter of the punch of the second punch rivet rod 4 is smaller than the rod diameter, so that the front end of the rod of the second punch rivet rod 4 is used to expand the unflanged edge 502 of the metal bushing 5 outward into place to complete the riveting.
[0015] There are five hollow rivet rod columns 2, with inner diameters of 15-17mm, 21-23mm, 11-13mm, 19-21mm, and 17-19mm, respectively, and wall thicknesses corresponding to the inner diameters of 4mm, 4mm, 10mm, 4mm, and 4mm.

The base 1, the first punch rivet rod 3, the second punch rivet rod 4, and the hollow rivet rod column 2 are all made of No. 45 steel. No. 45 steel has good plastic toughness, high strength, high strength, and good cutting processability.
[0017] When the metal bushing 5 is installed in the bushing hole of the seat frame component and the flanged edge 501 is placed on the top of the hollow rivet rod column 2, the front end of the punch of the first rivet rod 3 can be inserted from top to bottom through the metal bushing 5 into the hollow rivet rod column 2, and when struck by a hammer, the rear end of the punch of the first rivet rod 3 can open the unflagged edge 502 of the metal bushing 5 outward; when the first rivet rod 3 is removed, the front end of the punch of the second rivet rod 4 can be inserted from top to bottom through the metal bushing 5 into the hollow rivet rod column 2, and When struck by a hammer, the rear end of the punch of the first rivet rod 3 can open the unflanged edge 502 of the metal bushing 5 outward. During the riveting process, the metal bushing 5 will not slide left and right due to uneven force on the rivet rod, which will affect the quality of the flanging of the rivet rod. The metal bushing 5 is evenly stressed, and the riveted flanging effect is better. A plurality of rivet rod columns of different sizes and specifications are provided, which can be suitable for the riveting of metal bushings 5 of different specifications.
