Abstract
The utility model relates to an ejector pin hole-sleeve detaching tool, which comprises a rod body. A hanging hole is disposed at one end of the rod body, the other end of the rod body is connected to one side of a squeezing plate, the other side of the squeezing plate is connected with an impacted head, and the squeezing plate is larger than the inner diameter of an ejector pin hole-sleeve to be detached and smaller than a sleeve hole for mounting the ejector pin hole-sleeve to be detached. The ejector pin hole-sleeve detaching tool is convenient and fast in use, and resolves the problem that ejector pin hole-sleeve replacement operation is quite difficult, wastes labor and materials and consumes long time.
Description
Technical field
The utility model relates to instrument, relates in particular to a kind of top thick stick borehole jack extracting tool.
Background technology
At stamping factory, need use mould and carry out punching parts, and when ferrous material is struck out solid shape, drawing operation is wherein arranged one, and drawing die need use the top thick stick, in the process of punching production, top thick stick borehole jack damages easily, when it was changed, after table surface need being pulled down, the top thick stick borehole jack to damaging slowly beat from bottom to top again, beat out in thick stick hole, top until top thick stick borehole jack, but owing to the tight fit that is installed as in top thick stick borehole jack and bench top thick stick hole, be by external force top thick stick borehole jack to be beaten firmly to enter in the thick stick hole, top when mounted, very difficult when removing; And after need leaving workbench in certain height when beaing, beat by 2-4 people's cooperation, sometimes the top thick stick borehole jack that more needs to utilize die to damage slowly reams, and just can change, and it is operated very difficulty and waste of manpower, material resources and needs long time just can finish.
Summary of the invention
The utility model provides a kind of easy to use, top thick stick borehole jack extracting tool efficiently, has solved to operate very difficulty and waste of manpower, material resources when changing top thick stick borehole jack and need long time just can finish the problem that more changes jobs.
Above technical problem solves by following technical proposal: a kind of top thick stick borehole jack extracting tool, comprise the body of rod, one end of the described body of rod is provided with lifting hole(eyelet), the other end of the described body of rod connects stripper plate one side, the opposite side of described stripper plate connects hit head, and described stripper plate trepanning bigger than the top thick stick borehole jack internal diameter that is disassembled, that use than installation demolished top bar borehole jack is little." described stripper plate is bigger than the top thick stick borehole jack internal diameter that is disassembled, the trepanning that the demolished top bar borehole jack uses is little than installing " be meant stripper plate can be in the trepanning that the demolished top bar borehole jack is installed by but the meaning that can not pass through in the demolished top bar borehole jack; During use, the body of rod is located in the thick stick borehole jack of top, the end that lifting hole(eyelet) arranged up, reeve lifting hole(eyelet) this body of tool of slinging, can not from top thick stick borehole jack in pass because of stripper plate this moment, sling together so stud with the workbench of top thick stick borehole jack, upwards knocks hit head, under the gravity effect of percussion power and workbench itself, top thick stick borehole jack can very be removed like a cork.
As preferably, described stripper plate is circular, and described hit head is a cylinder, the described body of rod and described extruding disk, hit head three coaxial line, and described lifting hole(eyelet) is positioned at the centre of the described body of rod.With the form fit of demolished top bar borehole jack, coaxial line makes gravity and percussion power consistent at the axis direction of the direction of same straight line and power and top thick stick borehole jack, and is more laborsaving during dismounting.
As preferably, the diameter of the described body of rod is littler 0 to 5 millimeter than the internal diameter of the top thick stick borehole jack that is disassembled.Rock for a short time when knocking, the easier axis of the body of rod that makes is consistent with the axis of top thick stick borehole jack.
As preferably, the diameter of described extruding disk is littler 0 to 1 millimeter than the external diameter of demolished top bar borehole jack.Top thick stick borehole jack stressed effect is good, easier being removed of top thick stick borehole jack.
As preferably, the diameter of described hit head is greater than the internal diameter of described demolished top bar borehole jack, less than the external diameter of described demolished top bar borehole jack.Stripper plate is difficult for being struck bad when knocking.
As preferably, be rounded down between the side of described hit head and the free end face.The hit head free end is difficult for outwards upset, long service life when knocking.
As preferably, the described body of rod, extruding disk, hit head three are structure as a whole.Handling ease, align easily in three's axis, and the bonding strength between the three is good.
The utlity model has following advantage, 1, simple and reasonable, easy to process, convenient and swift during use; 2,, shortened the time of taking out top thick stick borehole jack by using specific purpose tool; 3, alleviated personnel labor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a user mode schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.Referring to Fig. 1, a kind of top thick stick borehole jack extracting tool, comprise the body of rod 1, the upper end of the body of rod 1 has lifting hole(eyelet) 2, the lower end of the body of rod 1 is connected on the upper surface of stripper plate 3, be connected with hit head 4 on the lower surface of stripper plate 3, the body of rod 1 is cylindrical, and lifting hole(eyelet) 2 is positioned at the centre of the body of rod 1, and lifting hole(eyelet) 2 is a circular port, can be consistent so that both sides were stressed when this body of tool was sling, and alignment to the midline automatically, not run-off the straight, stripper plate 3 is circular, hit head 4 is cylindrical, the body of rod 1, stripper plate 3, hit head 4 threes are structure as a whole and three's coaxial line, and the lower surface of hit head 4 and the side of hit head are arc transition, when the lower end of knocking hit head like this is free end, the bottom of hit head is difficult for producing flop phenomenon, can make the longer service life of this instrument;
Referring to Fig. 2, the diameter of stripper plate 3 is littler 0.5 millimeter than the external diameter of the top thick stick borehole jack 5 that is disassembled, the diameter of the body of rod 1 is littler 3 millimeters than the internal diameter of top thick stick borehole jack 5, the diameter of hit head 4 is littler than the diameter of stripper plate 3, bigger 2 millimeters than the internal diameter of top thick stick borehole jack 5, during use, after the body of rod 1 passed top thick stick borehole jack 5 by the below of the top thick stick borehole jack 5 in the workbench 6, utilizing steel wire rope 7 to be enclosed within lifting hole(eyelet) 2 backs is connected with driving 8, instrument is sling in driving 8, because of the diameter of stripper plate 3 bigger than the internal diameter of push rod borehole jack 5, so workbench is sling together, utilize iron hammer that hit head 4 is beaten again, because of the diameter of stripper plate 3 littler than the external diameter of push rod borehole jack 5, like this under the acting in conjunction of gravity and percussion power, stripper plate 3 just will be extruded in the trepanning of top thick stick borehole jack 5 from the workbench 6, because the body of rod 1, stripper plate 3, hit head 4 three's coaxial lines and lifting hole(eyelet) 2 are opened in common centre position, during so sling, the axis of this instrument is consistent with the axis of top thick stick borehole jack, the direction of gravity and percussion power is consistent with the direction of axis, and it is laborsaving to work.
