Technical field
The utility model belongs to part connection and maintenance technique field, and in particular to a kind of for rivet and boxing nut
Hydraulic disengaging tooling.
Background technology
The case where rivet, boxing nut, spot welding nut etc. need forcible entry can be often encountered in repair and manufacturing field.For example,
Connect in such a way that rivet or bolt add boxing nut between railway freight-car 120/120-1 air shut-off valves protective cover and upper cover
It connects, since 120/120-1 air shut-off valves are the important components of railway freight-car safe operation, often need to be overhauled or be replaced,
This just need by protective cover rivet or boxing nut forcible entry.For example, railway freight-car coupler buffer unit is in maintenance process,
Couple yoke supporting plate bolt and nut must be dismantled, since a little bolt and nut service conditions in this position are severe, frequent rust joint is serious, and dismounting is tired
Difficulty, or even can not dismantle, this just needs to dismantle nut.For another example in the manufacture of large-scale load truck vehicle frame, riveting
It is most common fastening means, in the practical fabrication stage, because of riveting mistake existing for more than riveting location, implements change in design, each
Class formation failure does over again, reprocess and for different customer demands repacking etc., be required for dismantling rivet.
Currently, for it is this kind of forcible entry generally use be bore striking, carve rush method, annulus dismounting method, annular groove rive method and
O2-C2H2 cutting method；The main problem of this kind of forcible entry method is in decomposable process, connecting portion will be caused nothing occur when serious
Method continues to rivet or the problems such as gap influences performance occurs after riveting, and used tool is numerous in the forcible entry of all kinds of riveting parts
It is more, riveting parts are taken and easily damaged, riveting pore size is increased.

And the positioning and guiding bar for cutter body and U-type groove to be connected.
Further, the junction of transverse slat and riser is symmetrically arranged with two pieces of floors.
Compared with prior art, the utility model has technique effect beneficial below：
The orcible entry frock clamped one time of the utility model can dismantle the rivet on multiple same straight lines, once can be real into grade
The rivet of existing different-diameter or bolt forcible entry, it is simple and compact for structure, it can be significantly improved compared to traditional rivet forcible entry mode
It dismantles efficiency, reduce labor intensity, cutter, the hydraulic cylinder that the rivet forcible entry special tooling of the utility model uses are replaceable, answer
It is wide with range, corresponding cutter and hydraulic cylinder can be designed according to the diameter difference of forcible entry type and connector, and hydraulic cylinder exports
Power configuration is larger, disclosure satisfy that the gapless forcible entry of rivet within the scope of 5~50mm；The hydraulic cylinder and cutter of orcible entry frock are replaced,
The rivet and bolt of different-diameter and material can be dismantled, the utility model realizes the broken of rivet or boxing bolt using shearing force
It tears open, forcible entry is realized by the fracture of manufactured head or bolt head, not connecting hole, there is no the accidental injurys bored in striking, to ensureing to connect
Connecing pore size has remarkable effect, and it is that power source is not necessarily to electric power, gas station etc. that hydraulic hand-pump, which can be used, in the utility model, can be in incapability
It is used under the environment of source, it is highly beneficial in external environment out of office.
Further, the utility model can adjust pending workpiece and hang down by the way that supporting studs and screw-thread bush is arranged
The upward position of histogram.
Further, the utility model can adjust pending workpiece in level by the way that fastening stud and branch fastener is arranged
Position on direction.
Further, it can ensure that cutoff knife rack will not be turned over along the centre of gyration of connecting pin by using rectangular connecting pin
Turn.

Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
The utility model is mainly used in repair and the maintenance of iron industry of automobile assembly line or daily all kinds of machinery equipments
It uses, the connection that can be dismantled includes：Rivet interlacement is bolted, on same straight line there are one or multiple rivets, be bolted need
The plate parts etc. to be dismantled.
Referring to Fig. 2-Fig. 7, the utility model dismantles the deficiency of efficiency for existing rivet and boxing screw thread pair, to being connected
The problems such as damage of part is larger provides the hydraulic disengaging tooling for rivet and boxing nut, including charged electric hydraulic pump
