Description
A kind of integrated steel bars machine belongs to the bar connecting apparatus in the construction.
Flourish along with building industry, the use amount of reinforcing bar is increasing.Some major diameters, high-intensity reinforcing bar are used in a large number, thereby the reinforcing bar connectivity problem has seemed more and more important.It is steel bar connecting machine that existing reinforcing bar connects the equipment that adopts usually, is also referred to as the steel bars machine, and it axially connects two reinforcing bars and puts sleeve pipe, by applying radially high pressure to the sleeve pipe periphery, makes sleeve pipe produce plastic deformation two reinforcing bars are coupled together.This extruder mainly is made of oil pump source, high-pressure conduit, extrusion head three parts.The oil pump source provides high voltage power by high-pressure conduit power to be imposed on to be used for squeezing bushing on the extrusion head and to make it plastic deformation, reach the purpose of connecting reinforcement.Existing extruder is owing to be made up of three parts, whole heavy, the lightest have about 70kg, and heavy reaches more than the 130kg, singly is that extrusion head just reaches 30kg, can only hang operation, operation inconvenience can not be handed during use, and the hydraulic oil in the high-pressure conduit has very high pressure in addition, easily high-pressure conduit is cracked, cause operating personnel's casualty accident easily.
The purpose of this utility model just provides the integrated steel bars machine of a kind of compact conformation, in light weight, easy to operate, safe in utilization and hand-holdable operation.
The utility model is following formation: integrated steel bars machine mainly comprises extrusion head, piston, oil cylinder, shell, piston pump, pumping chamber, main fuel tank, auxiliary fuel tank, spring, handle, motor etc.; Wherein: extrusion head is by the extruding patrix, the extruding counterdie, try to stop people from fighting each other form, the extruding patrix, the extruding counterdie is located in a shape tries to stop people from fighting each other, try to stop people from fighting each other with shell between the tenon formula be connected, the extruding counterdie that is positioned at the opening part of trying to stop people from fighting each other is connected with the top land of shell centre, piston is provided with switch valve and its periphery and oil cylinder inner wall slip and joins, the bottom centre of oil cylinder is provided with piston pump, oil cylinder top is connected with shell, the piston pump other end is connected with motor, the periphery of piston pump is provided with main fuel tank, be provided with the pumping chamber in the main fuel tank, for having the air of pressure, its role is to make keep certain pressure in the fuel tank forever in the pumping chamber, pumping chamber and main fuel tank contact portion are elastomeric material, when if micro-leakage takes place, expand the interior oil of fuel tank be under the certain pressure in the pumping chamber; The space that forms between piston, oil cylinder, the shell is an auxiliary fuel tank, is provided with spring between auxiliary fuel tank inside and outside shell and the piston, has oil pipe line to be interconnected between main fuel tank, auxiliary fuel tank, the piston pump.Can be provided with handle on the shell of extruder.During use, to try to stop people from fighting each other and be stuck on the shell, set reinforcing bar to be connected and sleeve pipe between the upper and lower mould of extruding in trying to stop people from fighting each other, provide power to piston pump by motor, the work operation of piston pump forms high-pressure extrusion between piston and the oil cylinder with the oil in the fuel tank, hydraulic oil promotes piston, the extruding counterdie moves to extruding patrix direction, and squeezing bushing makes it the plastic deformation lock ring and lives two reinforcing bars simultaneously, thereby two reinforcing bars are connected.
Integrated steel bars machine is an one not reducing under the existing extruder effect oil pump source, high-pressure conduit, extrusion head three segment sets, makes it compact conformation, volume is little, and weight reduces greatly, need not hang operation, hand-heldly just can operate.Cut high-pressure conduit, eliminated the danger that high-pressure conduit breaks and brought, safe in utilization, reliable, convenient.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a front view of the present utility model:
Wherein: 1. try to stop people from fighting each other; 2. extruding patrix; 3. extruding counterdie; 4. piston; 5. shell; 6. spring; 7. auxiliary fuel tank; 8. Oil Guide pipeline; 9. oil cylinder; 10. piston pump; 11. main fuel tank; 12. pumping chamber; 13. motor; 14. handle; 15. check valve; 16. switch valve; 17. motor switch; 18. seal washer;
Fig. 2 is the axonometric drawing of the utility model extrusion head:
Fig. 3 is the schematic diagram of sleeve pipe and two reinforcing bars to be connected: 19. reinforcing bars; 20. sleeve pipe; 21. reinforcing bar;
As shown in Figure 1, integrated steel bars machine mainly comprises extrusion head and the extruding main body be made up of piston, oil cylinder, shell, piston pump, pumping chamber, fuel tank, spring, handle, motor etc.; Extrusion head is by the extruding patrix, the extruding counterdie, try to stop people from fighting each other form (Fig. 2), semicircle extruding patrix is fixed on the shape top of trying to stop people from fighting each other, semicircle and top have the extruding lower die-sleeve of inserting rod also can be in the interior slip of trying to stop people from fighting each other in the bottom of trying to stop people from fighting each other, the two semicircle full circle that form relatively, the tenon formula is connected between try to stop people from fighting each other openend and the shell that pushes main body of door shape, the slotting rod of extruding counterdie is inserted in the middle T shape top land hole of shell also affixed with it, piston is provided with switch valve, the piston bottom end periphery is an oil cylinder, the bottom centre of oil cylinder is provided with piston pump, oil cylinder top and shell are affixed, the piston pump other end is connected with motor by motor shaft, the periphery of piston pump is provided with main fuel tank, be provided with the pumping chamber in the main fuel tank, for having the air of pressure, its role is to make keep certain pressure in the fuel tank forever in the pumping chamber, pumping chamber and main fuel tank contact portion are elastomeric material; The space that forms between piston, oil cylinder, the shell is an auxiliary fuel tank, is provided with spring in the auxiliary fuel tank, has oil pipe line to interconnect between main fuel tank, auxiliary fuel tank, the piston pump.The extruding main body is provided with handle.When the needs connecting reinforcement, at first two steel bar end butt joints are put sleeve pipe, will push patrix, extruding lower die-sleeve at sleeve pipe periphery (Fig. 3).Utilizing extrusion head to be connected with the tenon formula of shell then couples together extrusion head and shell.Because integrated steel bars machine integral body has only 30kg, therefore need not hang, staff can be taken moving extruder operation.During extruding, starter motor, the work of driven by motor piston pump forms high pressure with the oil that certain pressure is arranged in the fuel tank and injects piston bottom end, this hydraulic oil will promote piston effectively and move to extruding patrix direction, extruding patrix, extruding counterdie squeezing bushing make it to produce plastic deformation, are bumped into two reinforcing bars are connected.After this operation finishes, disable motor, piston pump quits work, open the switch valve on the piston, the hydraulic oil of piston base leaks in the auxiliary fuel tank, in auxiliary fuel tank under the effect of bullet Huang, piston is got back to original position, unloads extruding main body, extruding counterdie and extruding patrix successively, tries to stop people from fighting each other, and work finishes.This extruder is used for shearing or moment reinforcement because therefore conveniently replaced extrusion head, can be changed to extrusion head shear extrusion head, crooked extrusion head flexibly, forms a tractor serves several purposes.
