Detailed description of the invention
Below in conjunction with accompanying drawing, a most preferred embodiment of the present invention is described further, to help understanding content of the present invention.
As shown in Figure 1 to Figure 3, the present invention includes the knife rest 11 that entirety becomes " recessed " font, the leg on knife rest 11 both sides slightly outwards opens, the outside, middle part of described knife rest 11 is connected with swing arm 12 by axle 16, on knife rest 11, inside leg, summit place is provided with the first mold 1, inside knife rest 11 lower support legs, summit place is provided with the first bed die 13, and mould is connected by bolt 3 with knife rest 11; The centre of the first mold 1 and the first bed die 13 is provided with rectangular through holes, is provided with rectangle pushing block 2 with matching in through hole, and the left side of pushing block 2 is no more than mould left side; Near mould place, projection is set in knife rest 11 leg inner sides, in projection, is provided with the rectangular through holes matching with pushing block 2. In the through hole that pushing block 2 can arrange on the first mould 1 and knife rest 11, move. Evenly be provided with two internal thread holes at pushing block 2 away from mould one end, screw mandrel 4 is inserted in the internal thread hole of pushing block 2, screw mandrel 4 is fixedly connected with shaft coupling 5 one end away from pushing block 2 one end, the other end of shaft coupling 5 is fixedly connected with driven gear 6, driven gear 6 is connected with driving gear 8 by synchronizing jugged chain 7, driving gear 8 is fixedly connected with the output of reduction box 9, and the input of reduction box 9 is connected with motor 10 outputs.
Specific works mode:
The second mold 14 and the second bed die 15 clamp thin plate, start the hydraulic means of knife rest 11 tops, promote knife rest 11 and rotate around axle 16, after the first mould is adjacent to thin plate, continue to sway, and make thin plate bending, and the angle of now thin plate bending is 90 ° to the maximum. In the time that thin plate bending angle is greater than 90 ° by needs, start the motor 10 of thrust unit, motor 10 outputs are connected with reduction box 9 inputs, the output of reduction box 9 is fixedly connected with driving gear 8, drive driving gear 8 to rotate together, driving gear 8 drives driven gear 6 to rotate together by synchronizing jugged chain 7, because driven gear 6 is connected with screw mandrel 4 by shaft coupling 5, therefore can drive screw mandrel 4 to rotate together.
