Abstract
Box car lining pulling rivet Novel dismounting tool and method.There are oil-feed hand held structures and cutting to clamp.Rear end sets the pull action cylinder containing cylinder sleeve, piston in cutting pincers housing.The push action cylinder containing thrust piston is formed between cylinder sleeve and housing.Front end work head has:Claw, clamps the pulling rivet collar and is threadedly coupled with pulling piston during work；Claw sleeve, rear end is connected with cylinder sleeve, and front end has lozenges to adjust claw clamping and release；It is outer to be with the thrust outer shroud being connected with thrust piston and extension ring.Hydraulic pressure pump startup, pull action cylinder work, claw clamping flange disk post-tensioning；Pressurize；Oil circuit is changed；Push action cylinder works, extension ring reach, withstands on foundary weight, the collar is extracted from mounting hole.Solve that the finishing dismounting of existing lining is manually prized, to pound efficiency low, dangerous.This removal tool special, realize that simple in construction, clamping degree is big, interchangeability is good, esy to use, safe and reliable, save labor, efficiency high, cost it is low.Box car composite interior wallboard is applied not only to, other metallic plates and the dismounting of composite plate pulling rivet are can also be used for.
Description
(1) technical field：Box car lining pulling rivet Novel dismounting tool of the present invention and method, are related to a kind of for connecting
Connect the extracting tool of the special pulling rivet between composite plate and metallic plate.Belong to the riveting class (B21J) and fastener of metal machining
Class (F16B).
(2) background technology：
See Fig. 2, the lining of box car 23 in the composite plate 21 of rear side and the metal bead 22 of front side by constituting.Because of dress
The composite plate repaiied has the possibility often dismantled, thus this non-metal board that need to be dismantled of tradition and connected between metallic plate it is main
Method is screw.Although mode connects for screw is detachable, bonding strength is low, easy loosening, easy to fall off under goods collision.To this need
Connected between the metallic plate and non-metal board of dismounting according to common pulling rivet connection between existing two metallic plate, first in powerful riveting
Under power effect, composite board is just crushed easily, if even if in riveting, it is also very difficult when if desired dismantling.
It is thus desirable to provide a kind of be easy to riveting for have the lining pulling rivet of composite board for decoration in box car
With the technology of dismounting.At present, the P70 type box car linings newly made just employ a kind of following clinching method:1) Fig. 2 is seen, it is special
The nail rod 19 of pulling rivet stretched backward by mounting hole 24 on front side of the lining.2) on rear side of lining after dress foundary weight 20, the collar 18
Stretch on rear side of the lining in mounting hole and to be riveted with nail rod deformable squeeze.Structure is shown in Fig. 2 after riveting:Mark 19 is after breaking in figure
Rivet bar, mark 18 for extruding after the collar, mark 18a for set take capel.
As mentioned above, it is necessary, the composite plate of decoration need to be changed during this box car lining maintenance, or rivet in an installation
It is required to dismantle lining pulling rivet when nonconforming, then rivets again.
Middle Country patents disclose one kind<Box car lining pulling rivet extracting tool and method for dismounting>(publication number
CN104923706A, application number 201510355034.7).This solves the sled used now, pound mode belt removal
Inefficiency, security it is poor, and the foundary weight 20 of the outer surface dismantled is the problem of can not reuse.But, the dismounting work
Have work head and there is following deficiency:1) because working head structure is complicated, easy wearing detail is more and is difficult to change；Cause manufacturing cost it is high,
Service life is low.2) work head clamping pulls jaw pull bar, pull bar U-shaped mouth, center connecting pin, then band using pulling piston connecting rod
Moved behind dynamic left jaw, right jaw center, now left and right preceding connecting pin Tapes moves left jaw, right jaw and gradually closed along longitudinal direction rotation
Close, two jaws are split set take capel 19a from circumferential embedded clamping.Pinching action is complicated during work, and to the folder of the pulling rivet collar
Tight effect is bad.3) it is approximately two-point locating mode when the distance rod of the extracting tool withstands foundary weight, stability is poor, and easily
Foundary weight is caused to deform.Therefore, it is related to box car lining pulling rivet in patent CN104923706A is retained and unloads instrument and side
A kind of box car lining new pulling rivet extracting tool must be developed while the advantage of method.
(3) content of the invention：The new pulling rivet extracting tool of box car lining proposed by the present invention and method, its purpose it
One is exactly to solve existing lining pulling rivet extracting tool to dismantle using sled, the mode of pounding, and can not facilitate asking for installing/dismounting
Topic.The second purpose is that open extracting tool and method are improved.A kind of drawing for riveting nonmetallic and metallic plate is provided
The removal tool special of rivet.

It is upper that the control button 17 interlocked with external hydraulic pump and oil circuit control section is housed.
The present embodiment method for dismounting of above-mentioned box car lining pulling rivet Novel dismounting tool, comprises the following steps：
1) see Fig. 1, press control button 17, the pressure oil that external hydraulic pump is provided is entered by pull action cylinder oil inlet pipe to be drawn
Power cylinder 2, makes pulling piston 3 be moved rearwards by compressing rear end compression spring 4, while pulling piston front end sequentially drives pulling piston
Bar 3.2, claw 10 are moved rearwards by, and now with claw sleeve 11 relative motion occurs for claw, and lozenges 11.1 forms crowded to claw
Pressure, claw radial contraction realizes clamping to pulling rivet collar ring flange 18a, until tension spring 4 reaches stroke, after stopping
Move and pull.
2) Fig. 1, Fig. 4 are seen, pull action cylinder pressure, which rises, reaches setting pressure value, and outside oil pump stops pressurization, and does pressurize
Processing；Outside oil circuit control section automatic conversion, makes external pressure oil enter push action cylinder by push action cylinder oil inlet pipe simultaneously
7, it is allowed to move forward to the pressurization of thrust piston 8, sequentially promotes thrust outer shroud 12 and extension ring 13 to move forward, extension ring withstands on what is be riveted
On foundary weight 20.
3) see Fig. 1, Fig. 5, persistently oil in push action cylinder chamber is pressurizeed, extension ring applies thrust P13 to foundary weight；In pulling force oil
The claw post-tensioning of cylinder pressurize and clamping collar is acted on simultaneously under, make the pulling rivet collar overall and pull out from being riveted in plate mounting hole 24
Go out.
4) Fig. 1, Fig. 3, Fig. 6 are seen, pulling force and push action cylinder start pressure release, and tension spring resets elongation, promotes claw 10
Move forward, lozenges 11.1 is separated, and claw 10 is resetted, and now the hole of front end plate-like claw 10.1 is opened, aperture, which is more than, covers around-France
Blue disk diameter D18；Thrust spring 9, which resets, simultaneously shrinks, and pulls shifting after thrust piston 8 to reset.Reset back pressure throw of lever B13 big
About take 13mm (see Fig. 6).
Hydraulic system is driven by controller, and controller is connected with pressure sensor, and rivet, which clamps oil circuit, has pressure detecting
And pressure keeps function.
