Embodiment
The special-purpose pulling rivet of railway freight-car as shown in Figure 1; have pulling rivet main body 1, the collar 2; pulling rivet main body 1 is made up of pulling rivet head 11, pulling rivet shaft; the pulling rivet shaft is followed successively by polished rod section 12, locking annular groove section 13 and tailing screw flight section 14 from top to bottom, and 14 places are provided with guard member 3 in the tailing screw flight section.The shape and the size of locking annular groove section 13 and tailing screw flight section 14 are all inequality.The external diameter of pulling rivet shaft is also variant, and order from large to small is polished rod section 12, locking annular groove section 13, tailing screw flight section 14, and such size sequencing helps the riveted joint of pulling rivet.
Below the utility model is further described again:
(1), prevent situations such as getting rusty in use appears in tailing screw flight section 14, bad tooth, collision deformation, 14 places are provided with guard member 3 in the tailing screw flight section.
The utility model is used to rivet the railway freight-car coupler supporting base, outside the tailing screw flight section 14 of the special-purpose pulling rivet of railway freight-car can be exposed to after the installation, without any protective measure, in the working procedure of railway freight-car, can collide with miscellaneous part, cause screw thread snaggletooth, bad tooth, collision deformation to occur; Outside tailing screw flight section 14 is exposed to; wind and weather can quicken getting rusty of tailing screw flight section 14; just can not reuse again having damaged the drop-down rivet body 1 of tooth form or the situation of getting rusty; so the utility model is after the special-purpose pulling rivet installation of railway freight-car; can be provided with guard member 3 at tailing screw flight section 14 places; one can protect the complete of thread profile, two can protect screw thread can not get rusty the influence reuse.To after date, take off the guard member 3 of tailing screw flight section 14 in the special-purpose pulling rivet life cycle of railway freight-car, sever the collar 2 of locking on the annular groove 13 with special-purpose cut device, pulling rivet main body 1 just can continue to use.
The utility model is provided with guard member 3 for preventing situations such as getting rusty in use appears in tailing screw flight section 14, bad tooth, collision deformation in tailing screw flight section 14.Tailing screw flight section 14 can be processed into outside thread, also can be processed into internal thread.When tailing screw flight section 14 is processed into outside thread, can select nut, plastic cement protecting jacket etc. for use in the guard member 3 that tailing screw flight section 14 is provided with; When tailing screw flight section 14 was processed into internal thread, the guard member 3 that is provided with in tailing screw flight section 14 need be selected the bolt that can match with tailing screw flight section 14 internal threads, plastic cement guard column etc. for use.
(2), in order to prevent the stolen of pulling rivet, serious potential safety hazard appears, described guard member 3 is anti-theft nut or anti-theft bolt.
The utility model is prevent pulling rivet stolen, serious potential safety hazard occurs, and guard member 3 is designed to anti-theft nut or anti-theft bolt.After the special-purpose pulling rivet installation of railway freight-car, tailing screw flight section 14 is installed the anti-theft nut that matches with special-purpose each specification of pulling rivet of railway freight-car, can effectively prevent the stolen of the special-purpose pulling rivet of railway freight-car, improves the safety coefficient of railway freight-car fortune dress.
The anti-theft nut that matches with the special-purpose pulling rivet of railway freight-car, after can selecting for use a kind of and tailing screw flight section 14 to tighten, the nut head is the antitheft solid split nut of turn-break type of fracture automatically, this anti-theft nut and tailing screw flight section 14 joints are provided with internal thread, internal thread length is 2/3 of tailing screw flight section 14 length, the internal thread leading portion is provided with than the bigger sleeve of locking annular groove 13 place's external diameters, sleeve just in time interacts with the collar 2, produce interaction force, further limited the axial motion of the collar 2, thickness and rivet length that the length of sleeve will be riveted according to the special-purpose pulling rivet of railway freight-car are selected.
The anti-theft nut that matches with the special-purpose pulling rivet of railway freight-car, also can select a kind of anti-theft nut that must use special tool just can shirk for use, the nut head of this anti-theft nut has the various shapes that are of little use such as circle, shaven head, triangle, selects for use the effect of the antitheft solid split nut of this anti-theft nut and above-mentioned turn-break type consistent.
(3), on locking annular groove section 13, still can be made circular movement by the riveted joint back, on described locking annular groove, have axial groove in order to prevent the collar 2.
The utility model for prevent the collar 2 at railway freight-car in running, because of circular movement appears in alternate load, the situations such as operating mode, friction increase gap of impacting, on locking annular groove 13, have axial groove, axial groove can be used punching press, also can be with various processing methods such as millings, only require that axial groove opens in locking annular groove 13 and the collar 2 contact-segments, axial groove length does not have specific requirement, but guarantee the special-purpose pulling rivet integral intensity of railway freight-car, axial groove length gets final product can play the 2 circumference radial motion effects of the restriction collar.Axial groove can effectively further limit the circumference radial motion of the collar 2, prevent coming off of the collar 2, can not influence the locking degree of the collar 2 and locking annular groove 13 again, Fig. 2 is to the structure situation of axial groove is not set on Fig. 1, and Fig. 3 is the structure situation that Fig. 1 is provided with axial groove.
In conjunction with embodiment of the present utility model, the installation steps of the special-purpose pulling rivet of railway freight-car are as follows:
1, the special-purpose pulling rivet of railway freight-car is penetrated in the attachment hole of the required riveting parts of hitch supporting base, the collar 2 is enclosed within on the special-purpose pulling rivet of railway freight-car.
2, special-purpose staking setting tool is threaded in tailing screw flight section 14, presses power switch, instrument start-up, tool head piston rod are firmly grasped pulling rivet tailing screw flight section 14, and the tool head anvil block promotes the collar 2 and presses to fixed plate, up to removing any gap.
3, the tool head anvil block begins the collar 2 is embossed on the groove of locking annular groove 13 of pulling rivet bar, up to the collar 2 plastic deformations take place, inwall clamps into locking annular groove 13.
4, the collar 2 locking annular groove 13 groove pressing mold locking finish reach the design clamping force after, withdraw from installation special tool.
5, on tailing screw flight section 14, anti-theft nut is installed, overall process is installed finishes.
6, when the collar 2 life cycles to after date, use special-purpose cut device that the collar is severed, anti-theft nut is backed out, pulling rivet main body 1 is changed the new collar 2 and can also be reused with guard member 3.
