The technical scheme that solves the problems of the technologies described above is: a kind of retaining mechanism of portable angle-bender, described retaining mechanism comprises: frame, be fixed on vertical slideway and horizontal slideway on the frame, at the bending machine head that the vertical slideway in drive mechanism lower edge and horizontal slideway move, also comprise the telescoping cylinder, adjustable shelf and the fixed mount that are positioned at bending machine head bottom; Cylinder seat one end hinged securement frame one end of described telescoping cylinder, hinged adjustable shelf one end of the expansion link of the telescoping cylinder other end; The fixed mount other end is fixed on bending machine head bottom; The adjustable shelf other end swingingly leaves or exposure level slideway one side about under the expansion link driving.
The beneficial effects of the utility model are: the utility model overcomes the defective of prior art, and simple in structure being convenient to changed, and cost is low, and is easy to operate, easy to maintenance, stable working.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 the utility model front view; Fig. 2 is Fig. 1 left side view, also shows A-A cutaway view among Fig. 1.
As shown in the figure, the utility model provides a kind of retaining mechanism of portable angle-bender, and described retaining mechanism comprises: frame 11, be fixed on vertical slideway 13a and horizontal slideway 13b on the frame 11, drive the bending machine head 15 that the vertical slideway 13a in lower edge and horizontal slideway 13b move at driving mechanism (figure does not show).
The utility model also comprises telescoping cylinder 7, adjustable shelf 2 and the fixed mount 9 that is positioned at bending machine head 15 bottoms; Cylinder seat 8 one end hinged securement framves 9 one ends of described telescoping cylinder 7, expansion link 6 hinged adjustable shelf 2 one ends of telescoping cylinder 7 other ends; Fixed mount 9 other ends are fixed on bending machine head 15 bottoms; Adjustable shelf 2 other ends swingingly leave or exposure level slideway 13b one side about under expansion link 6 drivings.Described telescoping cylinder 7 is cylinder or oil cylinder; Expansion link 6 is the piston rods on cylinder or the oil cylinder.
The right flank of described adjustable shelf 2 other ends and left surface are respectively arranged with projection 18 and groove 19; Exposure level slideway 13b one side behind projection 18 embedding mount holders 17 through holes when adjustable shelf 2 other ends are swung to the right, this mount holder 17 is the plates that are vertically fixed on bending machine head 15 bottoms and have through hole.The face that between projection 18 and the horizontal slideway 13b is contacts, and is shown as the inclined-plane among the figure and contacts.
Groove 19 inserted on the hook of spacing press strip 1 when described adjustable shelf 2 other ends were swung left, and this spacing press strip 1 is fixed on bending machine head 15 bottoms.
The structure of described expansion link 6 hinged adjustable shelf 2 one ends is: be provided with connector 4 between expansion link 6 and adjustable shelf 2 one ends, connector 4 one ends are inserted in the adjustable shelf 2 one end grooves and are hinged on the adjustable shelf bearing pin 3, and adjustable shelf bearing pin 3 is fixed on adjustable shelf 2 one ends; Connect the threaded end of expansion link 6 in the screwed hole of connector 4 other ends, nut 5 is fixed on connector 4 other ends with expansion link 6.
More particularly, bending machine head 15 comprises: the crooked head (not marking sequence number among the figure) of bending machine casing 10, moment reinforcement and be fixed on the cabinet base 12 of bending machine casing 10 bottoms.
Fixed mount 9 one ends insert in cylinder seat 8 one end slots of telescoping cylinder 7 and are hinged on the fixed mount bearing pin 16, and this fixed mount bearing pin 16 is fixed on the cylinder seat 8.
Bending machine head 15 bottoms are provided with slider roller 14, and this slider roller 14 is arranged on the vertical slideway 13a left and right sides and horizontal slideway 13b upper and lower sides, and vertical slideway 13a and horizontal slideway 13b move in the drive mechanism lower edge to be convenient to bending machine head 15.
Below the course of work of the present utility model is described.
When the needs moment reinforcement, bending machine head 15 is moved to the moment reinforcement desired location, starting telescoping cylinder 7 stretches out its expansion link 6 left, adjustable shelf 2 one ends are moved to the left with expansion link 6, adjustable shelf 2 other ends are swung to the right, projection 18 exposure level slideway 13b one side of adjustable shelf 2 other ends, bending machine head 15 is locked on the horizontal slideway 13b, bending machine head 15 beginning moment reinforcements.When bar bending finishes, start telescoping cylinder 7 its expansion link 6 is withdrawn to the right, adjustable shelf 2 one ends move right with expansion link 6, and groove 19 inserted on the hook of spacing press strip 1 when adjustable shelf 2 other ends were swung left, the level and smooth road 13b of bending machine head 15 leaving waters, bending machine head 15 begins to move.
