Abstract
The utility model relates to hot forming tool water channel plug dismantling device, comprises pull bar, and one end of pull bar is provided with the external screw thread corresponding with the screw on stick harness, and the other end is provided with diameter clamping part that is less, that coordinate with hand riveter; The outer of pull bar is arranged with the sleeve be slidably matched with pull bar, and the internal diameter of sleeve is less than the external diameter drawing swollen plug, and the inwall of sleeve is provided with helicla flute.The utility model utilizes longer sleeve and pull bar to realize drawing deep hole place the dismounting of swollen plug, coordinates hand riveter to promote operating efficiency, is applicable to produce in enormous quantities, makes pull bar not be subject to rotary torsion, the longer service life of pull bar simultaneously.The inwall of sleeve is provided with helicla flute, and spiral fluted exhaust effect ensure that sleeve and pull bar can easy slide when fit clearance is less, makes sleeve and pull bar have good axiality, ensure that the installation effect of drawing swollen plug; Simultaneously helicla flute also has the effect of despumation, avoids use procedure middle sleeve and pull bar is damaged by impurity.
Description
Technical field
The utility model relates to the disassembling fixture drawing swollen plug, is specifically related to hot forming tool water channel plug dismantling device.
Background technology
The cooling water channel overwhelming majority of hot forming tool all adopts depth drill to process.Therefore, need special water channel plug (die swell throat taps, mould draw swollen plug) to come shutoff water hole, leak to prevent mould.One is as shown in Figure 3 conventional draws swollen plug, and it is made up of plug tube 8 and stick harness 9, and stick harness 9 is provided with screw.During use, plug tube 8 coordinates with water hole, and stick harness 9 enters in plug tube 8 and plug tube 8 generation is radially expanded, and axial stress changes the radial expansion effect of plug tube 8 into, thus forms the sealing of effective high-pressure non-leakage.Prior art is carried out dismounting by a bolt and sleeve and is drawn swollen plug, when swollen plug is drawn in installation, swollen plug first will be drawn to put into water hole, bolt passes sleeve and is screwed in the screw on stick harness 9, use inner hexagon spanner to turn bolt, stick harness 9 is drawn in plug tube 8 so that the water hole of mould is blocked.When swollen plug is drawn in dismounting, bolt passes sleeve and is screwed into stick harness 9 li, uses inner hexagon spanner to turn bolt, pulls stick harness 9 until stick harness 9 departs from plug tube 8, then plug tube 8 taken out, complete unloading process.
In use find that prior art exists following point: sleeve and bolt length not, can not carry out the installation and removal of deep-hole plug; Torsion rotation is carried out to elongated bolt, the inadequate easy fracture of bolt strength; Need by inner hexagon spanner, when swollen plug is drawn in dismounting, not very convenient, when particularly needing operation in enormous quantities, affect work task efficiency; The axiality of sleeve and bolt can not ensure, the installation effect of swollen plug is drawn in impact.
Summary of the invention
The purpose of this utility model proposes a kind of hot forming tool water channel plug dismantling device, and this instrument can be applicable to the dismounting that swollen plug is drawn at deep hole place, can promote work task efficiency simultaneously; And this tool life is long, install effective.
Hot forming tool water channel plug dismantling device described in the utility model, comprise pull bar, one end of described pull bar is provided with the external screw thread corresponding with the screw on stick harness, and the other end is provided with diameter clamping part that is less, that coordinate with hand riveter; The outer of described pull bar is arranged with the sleeve be slidably matched with pull bar, and the internal diameter of described sleeve is less than the external diameter drawing swollen plug, and the inwall of described sleeve is provided with helicla flute.
Further, the length of described sleeve is not less than 200mm, and to realize the dismounting of deep hole place being drawn to swollen plug, and longer sleeve facilitates workman to take holds.
Further, described pull bar is made up of Cr12MoV steel, makes pull bar have higher hardness, intensity and good wearability.
The utility model has made improvement relative to prior art, utilizes longer sleeve and pull bar to realize drawing deep hole place the dismounting of swollen plug, coordinates hand riveter to promote operating efficiency, be applicable to produce in enormous quantities; Pull bar is not by rotary torsion simultaneously, the longer service life of pull bar.Sleeve lining is provided with helicla flute, and spiral fluted exhaust effect ensure that sleeve and pull bar can easy slide when fit clearance is less, makes sleeve and pull bar have good axiality, ensure that the installation effect of drawing swollen plug; Helicla flute also has the effect of despumation simultaneously, avoids use procedure middle sleeve and pull bar to be damaged by impurity.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Hot forming tool water channel plug dismantling device as shown in Figure 1, comprises and makes pull bar 4 by Cr12MoV steel, and one end of pull bar 4 is provided with the external screw thread 6 corresponding with the screw on stick harness 9, and the other end is provided with diameter clamping part 5 that is less, that coordinate with hand riveter 7.On pull bar 4, the tail end of diameter sudden change place and external screw thread 6 is equipped with rounding off, concentrates to prevent stress.The outer of pull bar 4 is arranged with the sleeve 2 be slidably matched with pull bar 4, and the length of sleeve 2 is not less than 200mm, and the internal diameter of sleeve 2 is less than the external diameter drawing swollen plug 1, and as shown in Figure 2, the inwall of described sleeve 2 is provided with helicla flute 3.
Fig. 3 is the common concrete structure drawing swollen plug 1, and it comprises plug tube 8 and stick harness 9 forms, and stick harness 9 is provided with screw.
Operation principle of the present utility model is: be first arranged on stick harness 9 by pull bar 4 by external screw thread 6, then the outer race upper bush 2 of pull bar 4 until sleeve 2 is conflicted plug tube 8.By clamping part 5 clamping on hand riveter 7, exert a force to pull stick harness 9 to realize drawing the swollen stifled of swollen plug 1 or taking out by hand riveter 7.
Above-mentioned hand riveter 7 can select Manual rivet pulling gun, such as two hand riveter, also can select other electronic or pneumatic hand riveters.
