Description
The utility model relates to a kind of rapid shaping Ribbed Bar extruding junctor, belongs to the technical field of extrusion machinery.
It is that two reinforcing bars of preparing to connect are inserted in the steel sleeves that the extruding of Ribbed Bar connects, and uses the extruding connection device, along the steel bushing radial compression, makes it produce a plastic deformation, and with the reinforcing bar as a whole method of attachment of combining closely; Diameter according to reinforcing bar, adopt different pressing molds, in order to guarantee bonding strength, adopt different pressing molds, at the different road number of every end crimping, guarantee that it connects area, for example single-ended connection of φ 20-40mm reinforcing bar, extruding road number does not wait with the 3-8 road, when extrusion equipment pushes, be that each end of steel bushing is pushed one after another, so joint of every extruding, working time is very long, efficient is also low, connects in order to finish a large amount of reinforcing bars, often need use many extruding junctors, and need the long working time, therefore demand urgently improving.
The purpose of this utility model is that a kind of rapid shaping Ribbed Bar extruding junctor will be provided, and it can overcome above-mentioned shortcoming, utilizes high-pressure hydraulic pump to drive hydraulic cylinder, by extrusion die, but makes the once just extrusion modling of every end, high efficiency.
The purpose of this utility model is achieved in that
A kind of rapid shaping Ribbed Bar extruding junctor, its 2 hydraulic pumps (1) are contained in frame (4) above the right part, each is connected in reversal valve (2) with oil inlet pipe (12) and oil return pipe (13) hydraulic pump (1), reversal valve (2) is connected to the A oil pocket (21) and the B oil pocket (22) of hydraulic cylinder (8) again with flowline (16) (17), piston (14) is positioned at the cylinder (8) of hydraulic pressure, hydraulic cylinder (8) is divided into A, B, the affixed dynamic pressure mould (5) of oil pocket (21) (22) piston rod (15) left end, dynamic pressure film (5) and level pressure mould (6) all are contained in the die body (25), pull bar (10) is housed on 2 reversal valves (2), and pull bar (10) and handle (11) are formed a link gear.
Walking roller (3) is housed below the frame (4).
Fig. 1 pushes the schematic diagram of junctor;
Fig. 2 junctor schematic diagram.
Now in conjunction with the accompanying drawings the structure of rapid shaping Ribbed Bar extruding junctor is described in detail:
By Fig. 1, ultrahigh voltage hydraulic pump station is equipped with 2 hydraulic pumps (1) and is contained in above the right part of frame (4), and the axle that walking roller (3) is equipped with in frame (4) bottom just is supported in bearing (18) hole, and protective cover (9) is contained in above the top pillar (20) of frame (4).
Each is connected in reversal valve (2) with oil inlet pipe (12) and oil return pipe (13) hydraulic pump (1), reversal valve (2) is connected in the A of hydraulic cylinder (8) again with flowline (16) (17), B oil pocket (21) (22), piston (14) is positioned at hydraulic cylinder (8), hydraulic cylinder (8) is divided into AB two parts oil pocket (21) (22), piston (14) left end connects a piston rod (15), the affixed dynamic pressure mould (5) of piston rod (15) left end, can insert steel bushing (23) and reinforcing bar (24) between level pressure mould (6) and the dynamic pressure mould (5), dynamic pressure mould (5) and level pressure mould (6) all are contained in the die body (25), level pressure mould carrying handle (7) is equipped with on die body (25) top, pull bar (10) and handle (11) are housed on two reversal valves (2), and pull bar (10) and handle (10) are formed a link gear.
Ultrahigh-pressure hydraulic pump (1) output hydraulic oil, enter reversal valve (2) by oil inlet pipe (12), send into the A oil pocket (21) of hydraulic cylinder (8) again by high-pressure oil pipe (16), pressure oil promotion piston (14) is moved to the left by piston rod (15) promotion dynamic pressure mould (5) and is moved to the left, at this moment the oil in the B oil pocket (22) is by the fuel tank of oil pipe (17) and reversal valve (2) rework solution press pump (1), dynamic pressure mould (5) extruding steel bushing (23), make it produce plastic deformation, reach with reinforcing bar (24) and closely be connected to form one, so change direction by reversal valve (2), make pressure oil enter in the B oil pocket (22) of hydraulic cylinder (8) again by oil pipe (17), piston (14) is passed to the right, so piston rod (15) drives dynamic pressure mould (5) and moves right, at this moment the oil of A oil pocket (21) also returns fuel tank by oil pipe (16) and reversal valve (2).The extruding of so just having finished an end connects.
During use, utilize the following walking roller (3) of frame (4) to make junctor move to processing site, connect power supply, starting switch, at this moment should note the motor above the hydraulic pump (1), whether its direction of rotation is correct, just steel bushing (23) is placed between level pressure mould (6) and the dynamic pressure mould (5), be close to level pressure mould (6), again reinforcing bar (24) is put into steel bushing (23), plate fixed handle (11) is so 2 reversal valves (2) are realized simultaneously operating by pull bar (10), when hydraulic oil enters A oil pocket (21), just realized the extruding action that dynamic pressure mould (5) is moved to the left, the big I of operating pressure is decided by the indication of the Pressure gauge above the hydraulic power unit, when pressure reaches required numerical value, just oppositely pulls handle (11) with regard to pressure release.
Adopt 2 hydraulic pumps can reduce separate unit hydraulic pump flow, reduce the power of drive motor, so also reduced energy consumption.
Compared with prior art rapid shaping Ribbed Bar extruding junctor has following advantages:
1, extruding connects to bar one-time, raises the efficiency 5-6 doubly;
2, equipment can move to on-the-spot the use;
3, joint distortion is little;
4, extruding connection yield rate reaches 100%;
5, energy-conservation about 30%.
