Description

A kind of plug puller
Technical field
This utility model is related to the disassembling fixture of auxetic plug in mould and in particular to a kind of plug puller.
Background technology
The cooling water channel overwhelming majority of hot forming tool is all processed using depth drill.Consequently, it is desirable to special water channel Plug blocking water hole, to prevent mould leak.Conventional water channel plug is made up of plug tube and stick harness, and stick harness is provided with screw.Make Used time plug tube is coordinated with water hole, and stick harness enters and makes plug tube produce expanded radially in plug tube, and axial stress is changed into the footpath of plug tube To bulking effect, thus forming effective high-pressure non-leakage sealing.Prior art dismantle water channel plug when, using bolt Through sleeve and be screwed in stick harness, turn bolt using inner hexagon spanner, pull stick harness until stick harness departs from plug tube, then will fill in Cylinder takes out, and completes unloading process.
Find that prior art has following point in use:Sleeve and bolt length are not it is impossible to carry out deep hole water channel The dismounting of plug;Torsion rotation is carried out to elongated bolt, the inadequate easy fracture of bolt strength;During bolt pulls stick harness The phenomenon of stick harness stripped thread easily occurs.
Content of the invention
The purpose of this utility model proposes a kind of plug puller, to solve the above problems.
A kind of plug puller described in the utility model, including sleeve, the first screw rod and the second screw rod, described first spiral shell External screw thread corresponding with the screw on stick harness is had on bar, the left end of described first screw rod is provided with the slide block in cylindrical shape, institute The diameter stating slide block is equal to the internal diameter of described sleeve, and the periphery of described slide block is provided with outerplanar, the left side of described slide block It is provided with the screw-threaded counterbore extending to the right, described second screw rod and described screw-threaded counterbore screw thread cooperation, a left side for described second screw rod End is provided with the screw rod head in prism shape, and the right side of described screw rod head is uniformly inlaid with some steel balls that can rotate, At least part of right side protruding from described screw rod head of every described steel ball;The internal diameter of described sleeve is less than the outer of plug tube Footpath, the internal diameter of described sleeve is not less than the internal diameter of plug tube, and the inwall of described sleeve left part is provided with corresponding with described outerplanar Inner plane, described slide block can be in the internal slide of the left part of described sleeve;The right side of described sleeve is fixed with packing ring, described Packing ring is made up of rubber, and the left end of described sleeve has and outward extends flange, and the external diameter of described flange is not less than described screw rod The minimum inscribed circle diameter of the right side of head, when the right side of described screw rod head withstands on described flange, some described steel Pearl all with described Hp contacts.
Further, the length of described sleeve is not less than 200mm.
As one kind preferably, described first screw rod and described second screw rod are made by Cr12MoV steel.
This utility model is made that improvement with respect to prior art, using longer sleeve to realize to the water channel at deep hole The dismounting of plug, cooperation electric wrench is to lift work efficiency it is adaptable to high-volume operates;Pull first by the second screw rod Screw rod, by inner plane and outerplanar carry out circumference spacing it is ensured that the first screw rod is not subject to rotary torsion, the use longevity of the first screw rod Life is longer;First screw rod can be fully mated with the screw on stick harness, and be ensure that by inner plane and outerplanar cooperation First screw rod does not operationally rotate, only move along a straight line, it is to avoid the screw on stick harness stripped thread and leads to the stick harness cannot The phenomenon taken out;Increase the frictional force between sleeve and plug tube using packing ring, reduce flange and screw rod using steel ball simultaneously Frictional force between head, it is to avoid the phenomenon of sleeve rotating occurs in operation;Make flange and screw rod using the rotation of steel ball Can smoothly relatively rotate between head, have the advantages that clean, clean and tidy compared with using lubricating oil.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of plug puller as shown in Figures 1 to 4, including sleeve 1, the first screw rod 2 and the second screw rod 4, the first spiral shell External screw thread corresponding with the screw on stick harness 13 is had on bar 2, the left end of the first screw rod 2 is provided with the slide block 3 in cylindrical shape, sliding The diameter of block 3 is equal to the internal diameter of sleeve 1, and the periphery of slide block 3 is provided with outerplanar 11, and the left side of slide block 3 is provided with to the right The screw-threaded counterbore 8 extending, the second screw rod 4 is provided with prism shape with the cooperation of screw-threaded counterbore 8 screw thread, the left end of the second screw rod 4 Screw rod head 5, the right side of screw rod head 5 is uniformly inlaid with some steel balls that can rotate 7, every steel ball 7 at least Divide the right side protruding from screw rod head 5;The internal diameter of sleeve 1 is less than the external diameter of plug tube 12, and the internal diameter of sleeve 1 is not less than plug tube 12 Internal diameter, the inwall of sleeve 1 left part is provided with inner plane 10 corresponding with outerplanar 11, and slide block 3 can be in the left part of sleeve 1 Slide in portion;The right side of sleeve 1 is fixed with packing ring 9, and packing ring 9 is made up of rubber, and the left end of sleeve 1 has and outward extends flange 6, the external diameter of flange 6 is not less than the minimum inscribed circle diameter of the right side of screw rod head 5, when the right side of screw rod head 5 withstands on flange 6 When upper, some steel balls 7 are all contacted with flange 6.
