Abstract
The invention discloses a slanting wedge knife holder which comprises a knife holder and a mounting frame which is positioned at the two ends of the knife holder and used for supporting the knife holder to vertically move, wherein the knife holder is provided with upper and lower knife holder rods which are spaced from each other by a set distance; the upper and lower knife holder rods are respectively used for mounting bending knives; the bending knives are arranged towards the direction of the central lines of the two knife holder rods; blades of the bending knives face the side surface of the knife holder; the two knife holder rods are connected to each other at the two ends to form a whole body so as to form a supporting part; the other side surface, different from the side surface with the bending knives, of the supporting part is a slanting surface; and a wedge which can vertically move is arranged on the slanting surface side of the supporting part and is provided with a slanting wedge surface which is matched with the slanting surface of the supporting part. The slanting wedge knife holder has a compact structure, occupies small stereo space, can provide larger power for driving the bending knives to carry out bending, can also accurately control the running distances of the bending knives, can realize bending towards the upper and lower directions with only need for changing the corresponding bending knives, is simple and convenient to operate and meets the requirements for a bending angle.
Description
Technical field
The present invention relates to a kind of wedge knife rest, belong to field of mechanical technique.
Background technology
When bending is carried out to steel plate, need the movement locus controlling bending tool, to reach the requirement of bending angle.Bending tool is arranged on knife rest usually, controls the motion driving knife rest, drive the motion of bending tool by drive unit.In order to realize towards the bending of different directions, usually need change different benders or adopt different knife rests, adding cost; On the other hand, in prior art, the bending power of steel plate bending required and be difficult to satisfy the demand to the precise requirements of bending angle simultaneously.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art, provides a kind of wedge knife rest, larger driving bending tool both can be provided to carry out the power of bending, accurately can control again the range ability of bending tool, meet the requirement of bending angle.
For solving the problems of the technologies described above, the invention provides a kind of wedge knife rest, it is characterized in that, comprise a knife rest and be positioned at knife rest two ends and support the installing rack that moves both vertically of knife rest;
Knife rest has upper and lower two knife rest bars at a distance of a setpoint distance, and be respectively used to installation one bending tool, bending tool is arranged towards the centerline direction of two knife rest bars, and blade is towards the side of knife rest;
Two knife rest bars are all connected at two ends and form support portion, and support portion and the another side of installing bending tool different are inclined-plane; The side, inclined-plane of support portion arranges a voussoir that can move both vertically, and voussoir has a cammed surface matched with the inclined-plane of support portion.
Voussoir is driven by the first drive unit be fixed on installing rack and moves both vertically.
Voussoir upper end has the projection of a protrusion, projection is arranged a through hole, and the locus between underbump and installing rack can hold lower first drive unit, and the driving shaft of the first drive unit stretches in the through hole of projection, is fixedly connected with voussoir.
Installing rack drives entirety to be in vertical motion by second drive unit be arranged on above installing rack.
Preferably, the first drive unit adopts differential servo hydraulic cylinder.
Preferably, the second drive unit adopts synchronous servo hydraulic cylinder.
The beneficial effect that the present invention reaches:
Wedge knife rest of the present invention, compact conformation, shared solid space is less; Both larger driving bending tool can be provided to carry out the power of bending, accurately can control again the range ability of bending tool, and wedge knife rest of the present invention, can realize carrying out bending towards both direction up or down, only need change corresponding bending tool, simple to operation, meet the requirement to bending angle.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present invention;
Fig. 2 is the longitudinal sectional view of wedge knife rest one end;
Fig. 3 is voussoir schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1-Figure 3, wedge knife rest 1 of the present invention is symmetrical arranged, and comprises installing rack 11 and a knife rest 12.Knife rest has upper and lower two knife rest bars 121 at a distance of a setpoint distance, and be respectively used to installation one bending tool 2, two bending tools and be oppositely arranged, blade is all towards the same side of knife rest.When needs carry out upward bending, bending tool 2 installed by knife rest bar 121 up, when needs carry out downward bending, bending tool 2 installed by the knife rest bar 121 of below, do not need to change knife rest, convenient and swift.
Two knife rest bars 121 are all connected at two ends and form support portion 122, and support portion 122 and the another side of installing bending tool different are inclined-plane 123.The side, inclined-plane 123 of support portion arranges a voussoir 13, and voussoir 13 has one and to match the cammed surface 131 contacted with the inclined-plane 123 of support portion.
Voussoir 13 upper end has the projection 132 of a protrusion, projection 132 is arranged a through hole 1321, locus below projection 132 and between installing rack 11 can hold lower first drive unit 3, first drive unit 3 is installed on installing rack 11, its drive rod stretches in the through hole 1321 of projection, be fixedly connected with voussoir 13, voussoir 13 driven by the first drive unit 3 and moves both vertically.
When voussoir 13 moves both vertically, the horizontal movement of band movable knife rack 12, makes the bending tool 2 on knife rest 12 move horizontally, converts moving horizontally of bending tool 2 to by moving both vertically of voussoir.First drive unit 3 is contained in the space between voussoir 13 and installing rack 12, makes compact conformation, and shared solid space is less.
Installing rack 11 drives entirety to be in vertical motion by second drive unit 4 be arranged on above installing rack 11.When installing rack 11 entirety moves both vertically, the first drive unit 3, voussoir 13 and knife rest 12 on it are all together in vertical motion, thus realize moving both vertically of the bending tool 2 on knife rest 12.
Second drive unit 4 is fixed on framework 5, and its drive rod is connected with installing rack 11, moves both vertically for drive installation frame 11 entirety.
In order to ensure the synchronism of knife rest two end motion, the second drive unit 4 adopts synchronous servo hydraulic cylinder.First drive unit 3 adopts differential servo hydraulic cylinder.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
