Description
Technical field
The utility model relates to a kind of circle shear auxiliary equipment of cold rolling finishing unit, particularly a kind of circle shear dismantling device.
Background technology
Circle shear is a kind of configurations equipment that finishing line is used to cut edge, Fig. 1 is the formation schematic diagram of circle shear, as shown in the figure, circle shear comprises cutter shaft 10 and following cutter shaft 20, hydraulic nut 11, shading ring 12, cutting edge 13 and hydraulic nut 14 are installed on the last cutter shaft 10 successively, following cutter shaft 20 is equipped with hydraulic nut 21, shading ring 22, cutting edge 23 and hydraulic nut 24 equally successively, wherein shading ring 12,22 and cutting edge 13,23 are enclosed within respectively on cutter shaft 10 and the following cutter shaft 20, and hydraulic nut 11,14,21,24 are threaded with last cutter shaft 10 and following cutter shaft 20 respectively.
After circle shear cutting edge 13,23 weares and teares aborning, jumps and mouthful can not satisfy production requirement, the circle shear cutting edge that just need more renew, remove cutting edge at 13,23 o'clock, and needing to remove earlier cutter shaft 10 up and down, hydraulic nut 11,21 on 20, shading ring 12,22 and old cutting edge 13,23, new cutting edge is installed subsequently, return dress shading ring 12 again, 22 and hydraulic nut 11,21.
The general iron staff that adopts is inserted in the hole of hydraulic nut outer ring when the dismounting hydraulic nut now, with manual back-out the in the loosening back of hydraulic nut, otherwise installs.The problem that this assembly and disassembly methods exists is: drop easily in the hydraulic nut dismounting, damage.The general substance 15KG of finishing rotary cutter fluid pressure nut rotates by both hands Bian Tuobian in the unloading process fully, owing to there is not specific purpose tool, hydraulic nut is circle and sliding again, and last a few ring manipulation personnel of dismounting rotation drop for preventing, can only by a hand rest, a hand-screw changes, and consumes one's strength very much.Even if like this, also have incessantly possibility of holder, break equipment easily or cause personal injury.
The utility model content
For addressing the above problem, the utility model provides a kind of circle shear dismantling device, eliminates the potential safety hazard in the disassembly process, improves operating efficiency.
For achieving the above object, circle shear dismantling device of the present utility model, comprise hydraulic nut support, connecting rod and knuckle buster, described hydraulic nut support middle part is provided with a mandrel that can be fixed on the circle shear, and described hydraulic nut support can rotate around described mandrel; Described hydraulic nut support is connected with described connecting rod by a contiguous block; Described knuckle buster is fixedlyed connected with described connecting rod, and described knuckle buster is provided with backstay and knocks bar.
Described hydraulic nut support is provided with at least one dovetail groove, and an end of described contiguous block is connected with described connecting rod, and the other end is provided with the dovetail that is complementary with described dovetail groove.
Offer groove on the described hydraulic nut support.
Described hydraulic nut support is cylindric.
Described knuckle buster is circular-arc.
Adopt circle shear dismantling device of the present utility model, make that the dismounting operation is convenient and swift, eliminated potential safety hazard, improved operating efficiency.

The specific embodiment
Fig. 2 is the stereogram of circle shear dismantling device of the present utility model, and Fig. 3 is the user mode schematic diagram of circle shear dismantling device of the present utility model.As shown in the figure, circle shear dismantling device of the present utility model comprises hydraulic nut support 100, connecting rod 200 and knuckle buster 300, described hydraulic nut support 100 middle parts are provided with a mandrel 110 that can be fixed on the circle shear, and described hydraulic nut support 100 can rotate around described mandrel 110; Described hydraulic nut support 100 is connected with described connecting rod 200 by a contiguous block 210; Described knuckle buster 300 is fixedlyed connected with described connecting rod 200, and described knuckle buster 300 is provided with backstay 301 and knocks bar 302.
Described hydraulic nut support 100 is provided with at least one dovetail groove 101, and an end of described contiguous block 210 is connected with described connecting rod 200, and the other end is provided with the dovetail 211 that is complementary with described dovetail groove 101.Adopt being connected of dovetail groove 101 and dovetail 211, make things convenient for separating and combination of hydraulic nut support 100 and connecting rod 200.
Described hydraulic nut support 100 is cylindric, and its diameter is not more than the internal diameter of hydraulic nut 11,21.The hydraulic nut 11,21 that disassembles can be held by described hydraulic nut support 100, does not need operating personnel with hand rest.One end of the mandrel 110 of described hydraulic nut support 100 is provided with hexagon column 111, and convenient spanner or the outer-hexagonal spanner of using can fastening installation mandrel 111, and the other end is provided with external screw thread 112, is used for connecting with the screwed hole of upper and lower cutter shaft 10,20 end faces.
Behind dismounting hydraulic nut 11,12, hydraulic nut 11,12 is enclosed within on the described hydraulic nut support 100, takes out for convenient, offers groove 102 on described hydraulic nut support 100.
Described knuckle buster 300 is circular-arc, and backstay 301 is positioned at the inboard of described knuckle buster 300, and described backstay 301 can insert in the circumferential locating hole of hydraulic nut 11,21.Knock bar 302 and be positioned at the outside of described knuckle buster 300, after described backstay 301 inserts the circumferential locating hole of hydraulic nuts 11,21, the described bar 302 that knocks that can hit with a hammer, thus can become flexible or fastening hydraulic nut 11,21.
Circle shear dismantling device of the present utility model is when dismantling, as shown in Figure 3, earlier mandrel 110 is screwed into the screwed hole of cutter shaft 11 end faces, after installing mandrel 11, put hydraulic nut support 100, and with the dovetail groove 101 on the dovetail 211 insertion hydraulic nut supports 100 of contiguous block 210, backstay 301 inserts in the locating hole of hydraulic nuts 11.Knock with hammer etc. and to knock bar 302 on the described knuckle buster 300, make hydraulic nut 11 loosening, shake knuckle buster 300 subsequently just hydraulic nut 11 to be screwed out to hydraulic nut support 100, can dismantle shading ring 12 and cutting edge 13 subsequently.Otherwise can be used for installing hydraulic nut 11.
