Abstract
The utility model relates to a hand-tool, which is used for pressure matched connecting objects, in particular to a hydraulic wire press joining pincers. The hydraulic wire press joining pincers is composed of a hydraulic mechanism, a pressure welding mechanism and a pressure mechanism. The pressure welding mechanism and the pressure mechanism are arranged on the hydraulic mechanism. The utility model is characterized in that the pressure mechanism comprises a bracket which is fixed to a barrel body and a handle head which is arranged on the bracket. The core of an oil pump is connected with a handle head together. The utility model has the advantages of modern design, lighter weight, little operation labour, high work efficiency, dependable performance, etc. The utility model mdoel is a novel tool for intermediate connection and end sealing for motility, lighting and cable installation.
Description
The utility model relates to the hand tools that is used for the pressured object that is connected, particularly the fluid pressure type conductor compression jointing tongs.
Existing fluid pressure type conductor compression jointing tongs, because the spacing in pressing mechanism central bearing point and force is bigger, pressure is less, thereby the Press Plier volume is bigger, relatively requires great effort during use.
The purpose of the utility model is to provide the spacing in a kind of pressing mechanism central bearing point and force less, pressure is bigger, thereby the Press Plier volume is less, compare the novel Press Plier in labour-saving when using.
Hydraulic conductor compression jointing tongs is made up of hydraulic mechanism and dress compression joint mechanism and pressing mechanism thereon.Hydraulic mechanism comprises cylindrical shell and dress oil pump overcoat, oil pump fuse, inlet valve, delivery valve, piston and return spring within it.Compression joint mechanism comprises the binding clip that is fixed on the cylindrical shell, is fixed on the movable mold on the piston, is fixed on the fixed die on the binding clip.Pressing mechanism is made up of with the handle head that handle head pin and support are linked together the support that is fixed on the cylindrical shell.The oil pump fuse is linked together with oil pump fuse pin and handle head.
Below in conjunction with embodiment shown in the drawings, the utility model is done detailed explanation.
Accompanying drawing 1 is the utility model front view, and accompanying drawing 2 is A-A cutaway views, and accompanying drawing 3 is existing fluid pressure type conductor compression jointing tongs pressing mechanism schematic diagrames.In accompanying drawing 1 and accompanying drawing 2: 1. handle, 2. oil pump fuse pin, 3. handle head, 4. handle head pin, 5. support, 6. fixed die, 7. movable mold, 8. binding clip, 9. return spring, 10. piston, 11. cylindrical shells, 12. delivery valve, 13. oil pump overcoats, 14. oil pump fuses, 15. inlet valves, 16. oil storage chambers.
Hydraulic conductor compression jointing tongs is made up of hydraulic mechanism and dress compression joint mechanism and pressing mechanism thereon.
Hydraulic mechanism comprises cylindrical shell 11, is contained in the oil pump overcoat 13 in the cylindrical shell 11, is contained in the oil pump fuse 14 in the oil pump overcoat 13, is contained in inlet valve 15, delivery valve 12, piston 10 and return spring 9 in the cylindrical shell 11.
Compression joint mechanism comprises the binding clip 8 that is fixed on the cylindrical shell 11, is fixed on the movable mold 7 on the piston 10, is fixed on the fixed die 6 on the binding clip 8.
Pressing mechanism is by the support 5 that is fixed on the cylindrical shell 11, and the handle head that connects with oil pump fuse 14 3 that is contained on the support 5 is formed.Support 5 can adopt thread connection with cylindrical shell 11, also can adopt its method to connect.Support 5 connects with handle head 3 armrest button pins 4.Oil pump fuse 14 connects with handle head 3 usefulness oil pump fuse pins 2.Obviously, handle head pin 4 is fulcrums, and oil pump fuse pin 2 is forces.The spacing in fulcrum of the prior art shown in the gap ratio accompanying drawing 3 in fulcrum and force and force is much smaller.
Operation principle of the present utility model is such: good corresponding movable mold 7 of apolegamy and fixed die 6, pull handle 1, and oil pump fuse 14 is risen, inlet valve 15 unlatchings this moment, the oil in the oil storage chamber 16 enters in the lower cavity of oil pump fuse 14 by inlet valve 15.When handle 1 past pressing down, inlet valve 15 cuts out, and delivery valve 12 is opened, oil in oil pump fuse 14 lower cavity is pressed into delivery valve 12, promotes piston 10 and forces return spring 9 compressions, and movable mold 7 is pushed ahead, the extruding lead makes lead and lead or lead and binding post crimping moulding.Unclamp the oil return screw then, oil return valve is opened, because the effect of return spring 9 is flowed back in the oil storage chamber 16 oil, movable mold 7 resets.
The utility model is made series of products.The crimping scope: hexagon end-blocking crimping cross section aluminum steel is 16～240mm
2, copper cash is 16～150mm
2Middle arc crimping cross section aluminum steel, the aluminium conductor steel rein 25～95mm of connecting
2The range of piston 10 is 22mm.
The utility model modern design, weight are light, rapid operation, high efficiency, dependable performance, are to connect in the middle of doing during power, illumination and cable are installed and the new tool of end-blocking.
Embodiment shown in the drawings is the hydraulic conductor compression jointing tongs of hexagon end-blocking.Support 5 and cylindrical shell 11 usefulness M16 * 1.5 thread connection, handle head pin 4 is of a size of φ 8 * 24.5, and oil pump fuse pin 2 is of a size of φ 8 * 14, and the external diameter of oil pump fuse 14 is 8.The overall dimension of whole Press Plier is 400 * 100 * 55.
