Abstract
The utility model discloses a kind of ladder rivet, its drip irrigation device comprises the rivet set, limited step, the rivet rod that are manufactured by the cold-heading of cold-forging steel one, described rivet rod is provided with the taper rivet hole of cold-heading drilling forming away from rivet set one end, rounding is provided with bottom described taper rivet hole, the described taper rivet hole degree of depth and rivet rod lenth ratio are 1/4 ~ 1/3, the zinc coat that surface has plating to be formed.
Description
Technical field
The utility model relates to a kind of mechanical parts field, and more particularly, it relates to a kind of ladder rivet.
Background technique
Ladder rivet is the accessory in automobile safety belt external member, safety being taken up to position-limiting action, ladder rivet forms a fixed transverse rod fixed for safety strip by riveting on fixed component, and usually process on lathe at this ladder rivet of production, easily burr is produced in turning process, reject rate is high, and operation is loaded down with trivial details, manufacturing efficiency is low, and when processing rivet hole, comparatively sharp-pointed bottom rivet hole, cause leaving one section of rivet hole after ladder rivet riveting, cause very ugly of product after riveting, and be not easy bottom rivet hole to plate resin layer, get rusty easily when causing ladder rivet to use, thus the safety coefficient greatly reduced when safety strip uses.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of easily manufactured, the ladder rivet not easily got rusty.
For achieving the above object, the utility model provides following technological scheme: a kind of ladder rivet, comprise the rivet set, limited step, the rivet rod that are manufactured by the cold-heading of cold-forging steel one, described rivet rod is provided with the taper rivet hole of cold-heading drilling forming away from rivet set one end, rounding is provided with bottom described taper rivet hole, the described taper rivet hole degree of depth and rivet rod lenth ratio are 1/4 ~ 1/3, the zinc coat that surface has plating to be formed.
Preferably, the cone angle of described taper rivet hole is 80 degree.
Preferably, the described taper rivet hole degree of depth and rivet rod lenth ratio are 2/7.
Preferably, described rivet rod diameter and limited step diameter ratio are 5/6.
Compared with prior art, the beneficial effects of the utility model are: ladder rivet integrated straight is connected on that Cold header carries out cold pier by supporting mould is shaping, because taper rivet hole effectively avoids the generation of rivet hole inner burr by cold-heading drilling forming, allow ladder rivet metal structure finer and closely woven simultaneously, effectively raise structural strength better, decrease process step, improve manufacturing efficiency, and due to rivet hole be taper, instead of original common blind hole, thus in the process of riveting, after rivet hole is under pressure, more easily balance is uniform to external diffusion, effectively avoid after pressurized to rivet hole center deformation, thus the fixed effect effectively raised after ladder rivet riveting, and the taper rivet hole degree of depth and rivet rod lenth ratio are 1/4 ~ 1/3, effectively avoid rivet rod distortion place and produce larger distortion, the ladder rivet making connection product thickness different all has identical riveting amount of deformation, thus make often to locate to use the join strength ratio of ladder rivet all identical, and owing to adopting cold-heading to form, make to produce rounding more easily bottom taper rivet hole, and it is more smooth in riveting rear surface, and taper rivet hole surface is especially more prone to zinc-plated in bottom, effectively raise rust-proof effect calmly, thus Safety performance when effectively raising use, and ladder rivet surface-brightening after ladder rivet copper coating, can also be allowed to have texture, and zinc-plated rear ladder rivet list mask has good lubricating ability and antirust ability, long-term antirust ability can be ensured.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the utility model ladder rivet embodiment.
Reference character: 1, rivet set; 2, limited step; 3, rivet rod; 4, rivet hole; 5, rounding.
Embodiment
With reference to Fig. 1, the utility model ladder rivet embodiment is described further.
A kind of ladder rivet, comprise the rivet set 1 manufactured by the cold-heading of cold-forging steel one, limited step 2, rivet rod 3, described rivet rod 3 is provided with the taper rivet hole 4 of cold-heading drilling forming away from rivet set 1 one end, rounding 5 is provided with bottom described taper rivet hole 4, described taper rivet hole 4 degree of depth and rivet rod 3 lenth ratio are 2/7, the zinc coat that surface has plating to be formed, ladder rivet integrated straight is connected on that Cold header carries out cold pier by supporting mould is shaping, because taper rivet hole 4 effectively avoids the generation of rivet hole 4 inner burr by cold-heading drilling forming, allow ladder rivet metal structure finer and closely woven simultaneously, effectively raise structural strength better, decrease process step, improve manufacturing efficiency, and due to rivet hole 4 be taper, instead of original common blind hole, thus in the process of riveting, after rivet hole 4 is under pressure, more easily balance is uniform to external diffusion, effectively avoid after pressurized to rivet hole 4 center deformation, thus the fixed effect effectively raised after ladder rivet riveting, and taper rivet hole 4 degree of depth and rivet rod 3 lenth ratio are 2/7, effectively avoid rivet rod 3 distortion place and produce larger distortion, the ladder rivet making connection product thickness different all has identical riveting amount of deformation, thus make often to locate to use the join strength ratio of ladder rivet all identical, and owing to adopting cold-heading to form, make to produce rounding 5 more easily bottom taper rivet hole 4, and it is more smooth in riveting rear surface, and taper rivet hole 4 surface is especially more prone to zinc-plated in bottom, effectively raise rust-proof effect calmly, thus Safety performance when effectively raising use, and ladder rivet surface-brightening after ladder rivet copper coating, can also be allowed to have texture, and zinc-plated rear ladder rivet list mask has good lubricating ability and antirust ability, long-term antirust ability can be ensured, and many experiments is when showing that taper rivet hole 4 degree of depth and rivet rod 3 lenth ratio are 2/7, constant intensity after riveting, counter-bending deformability is the strongest.
The cone angle of described taper rivet hole 4 is a, the angle of a is 80 degree, when the rivet rod 3 backward outer distortion that to be under pressure near taper rivet hole 4 one end is more easy, and the thickness produced after riveting is comparatively even, can not be blocked up and excessively thin, effectively ensure structural strength, and facilitate riveting, and when exerting pressure, also can be out of shape normally when the power inclination 30 degree of exerting pressure.
Described rivet rod 3 diameter and limited step 2 diameter ratio are 5/6, effective guarantee limited step 2 exceeds the thickness of rivet rod 3, thus the effective conflict area ensureing limited step 2 and product, thus effectively avoid producing when ladder rivet riveting, offseting, thus the operation of effective guarantee riveting can normally, effectively be carried out.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
