Description

Automatic control screw jack I-steel bullodozer

The utility model is that a kind of being used for specially belongs to I-steel press-bending field of mechanical technique to the I-steel automatic control screw jack I-steel bullodozer of operation that bends.

In some engineering construction such as tunnel, tunnel, often will make bracing frame, and these I-steel often to be suppressed into arc with I-steel.Common coiling machine is because insufficient pressure, only can crooked angle steel, channel-section steel etc., and can not bend I-steel.Special I-steel press-bending facility, the press-bending radius has limitation, can only accomplish that a mold bends a kind of I-steel of radius, and has the major defect that is pressed the easy torsional deformation of I-steel.

The purpose of this utility model is to provide an a kind of mold can suppress the I-steel of multiple radius, and can prevent to be pressed the automatic control screw jack I-steel bullodozer of the protruding abdomen distortion of I-steel.

The technical solution of the utility model is: automatic control screw jack I-steel bullodozer is foundation means, actuating unit, is anti-ly turned round mechanism and circuit mechanism forms jointly by quadruplet mechanism.The formation of foundation means is: at pedestal bottom plate is welding jack base plate 14 on the operating table surface 1, force column 6, and the stiffener 15 of jack base plate 14, the stiffener 16 of force column 6, bedplate 14 is strengthened I-steel 17.The formation of actuating unit is: electric reducer 2 is installed on operating table surface 1, and electric reducer 2 is connected with screw jack 3 by clutch 13, and the head of screw jack 3 is installed inner module 4.The anti-formation of turning round mechanism is: welding slide rail 9 on operating table surface 1, the two ends of slide rail 9 weld the I-steel of two settings respectively and prevent turning round stake 8; Anti-turning round in the stake 8 offered rectangular through holes 20, penetrates the anti-depression bar 7 of turning round of packing in the front and back through hole 20; The anti-head of turning round depression bar 7 inserts and anti-ly draws pin 18, is parallel to slide rail 9 on the both sides of operating table surface 1 pad rail 10 is set, and an end of slide rail 9 on perpendicular to the direction of slide rail 9 is an operating table surface 1 and prevent turning round to be provided with between the depression bar 7 highly to control rail 11 in pedestal bottom plate.The formation of circuit mechanism is: jack travel switch 12, protection travel switch 19, change-over switch, compensating switch, A.C. contactor.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof and operating process.

Figure 12 is the left view of Figure 11.

In conjunction with Fig. 2 and Fig. 3 as can be seen, the bottom surface of operating table surface 1 is welded with strengthens I-steel 17, be welded with two pad rails 10 and two one slide rails 9 on the table top, an end of slide rail 9 on perpendicular to the direction of slide rail 9, in pedestal bottom plate be operating table surface 1 and anti-turn round to be provided with between the depression bar 7 highly control rail 11, processed I-steel 5 is erected at pad rail 10 and above the slide rail 9.In conjunction with Fig. 2 and Fig. 1 as can be seen, processed I-steel 5 nestles up force column 6, in order to prevent processed I-steel 5 torsional deformation in processed process, the two anti-depression bars 7 of turning round that pressurizeed above, anti-two of turning round depression bar 7 is fixed in the middle of being through the anti-square hole 20 of turning round stake 8; Prevent that in order to prevent that processed I-steel 5 from driving in the quilt process that bends turning round depression bar 7 moves, special at the anti-anti-pin 18 that draws of front end insertion of turning round depression bar 7.

Operating process of the present utility model is as follows:

1, assembles inner module 4, regulates jack travel switch 12 by required I-steel radius requirement.

2, worker to be processed is made 5 of steel on slide rail 9, pad rail 10 and to be close to force column 6 in place.

3, will prevent turning round depression bar 7 and pass the anti-slot of turning round in the stake 8 20, push down I-steel to be processed 5, and plug the anti-pin 18 that draws, in case the anti-depression bar 7 of turning round produces slippages during operation at the anti-head of turning round depression bar 7.

4, the change-over switch of pressing motor reducer 2 is put to positive transposition, and screw jack 3 is slowly moved, and forward stretches out and touches I-steel to be processed 5, and then and the I-steel to be processed 5 that bends.When the I-steel that bends touched jack travel switch 12, electric reducer 2 was shut down.

5, the change-over switch of electric reducer 2 is beaten to backward position, pinned compensating switch, electric reducer 2 counter-rotatings, screw jack 3 reclaims; After treating that screw jack 3 is recovered to jack stroke beginning 12 and resets, decontrol compensating switch.

6, after screw jack 3 continues to reclaim certain stroke, the change-over switch of electric reducer 2 is beaten at neutral position, electric reducer 2 is shut down.Or when jack backhaul protection travel switch 19 was touched, electric reducer 2 was shut down.

7, with 6 whiles of operation, extract and prevent drawing pin 18, withdraw from the anti-depression bar 7 of turning round, processed I-steel 5 is shifted to next section, do the press-bending of next section.

8, repeat above-mentioned 2-7 step, until processed I-steel 5 completion of processing.

The utility model is simple in structure, and flexible operation is made easily, and is sturdy and durable, can guarantee the I-steel accurate forming.As long as assemble inner module 4 and regulate jack travel switch 12, just can bend the I-steel of different radii requirement, need not make external mold, the I-steel flank portion that bends moulding is non-warping.The utility model is the very strong machining machine and tool of a kind of practicality, has wide production promotion prospect.
