Technical field
The utility model belongs to sheet metal component manufacturing and processing equipment field, relates generally to a kind of plate edge folding machine structure.
Background technology
That at sheet metal component production and processing field sheet material bending and molding, uses at present, has hydraulic bending press, Pneumatic reverse turning bed formula bender and a Manual turning plate type bender.
Figure 18 gives the signal that has hydraulic bending press, and General hydraulic bender is comprised of critical pieces such as frame 61, framework platform 62, jack knife beam 66, jack knife 65, counterdie 63, driving oil cylinders 67.Described jack knife beam 66 is simply supported beam forms.Two point is at place, simply supported beam both sides, and two driving cylinder piston rods are fulcrum, and cylinder block and frame connect firmly.Jack knife beam 66 is arranged in the slide of frame both sides setting.The framework platform 62 relatively arranging in frame under cylinder piston rod promotes moves up and down.Jack knife 65 is arranged on the bottom of jack knife beam 66 and connects firmly, and counterdie 63 is fixed on framework platform 62.65 of jack knives are V-arrangement cutter head, and counterdie 63 is with V-shaped groove.V-arrangement cutter head can coincide in counterdie V-shaped groove.Its course of work is: on counterdie V-shaped groove, place after sheet material 45, under the driving of cylinder piston rod, jack knife beam 66 moves down with V-arrangement cutter, and while jack knife being fallen in the V-shaped groove of counterdie 63, sheet material is by bending.Under cylinder piston rod pulls, jack knife beam 66 rises, and jack knife 65 shifts out counterdie V-shaped groove, and sheet material 45 is bent into type.This process is by hydraulic cylinder, to drive jack knife beam to move up and down to form unidirectional bending.Because the bending principle of this type of bender is to be entered downwards in the V-shaped groove of upper plane and carried out bending by the moving V-knife head of jack knife sill bolt.On another V-shaped groove mould bottom surface and framework platform, plane is fixed on above framework platform.Be that existing hydraulic bending press is by the moving up and down of jack knife beam 66, rely on the coordinating of V-shaped groove of V-arrangement cutter head and upper plane, realize the unidirectional bending of sheet material.
In conjunction with Figure 19, Figure 20, Figure 21, Figure 22,23, Pneumatic reverse turning bed bender is by frame, upper trave lling girder 92, forming cutter 93, framework platform 62, gear 97, tooth bar 98, rack guide rail 99, upper trave lling girder pull bar 100, slide 101, rotating shaft cover 102, rotating shaft 103, bending turnover panel 104, cylinder I 105, bearing pin I 106, gear rocking arm 107, cylinder II 108, bearing pin II 109 critical pieces such as grade form.Upper trave lling girder 92 is simply supported beam forms, and upper trave lling girder 92 is arranged in the slide 101 of frame both sides setting, on one side upper trave lling girder 92 upper ends are provided with trave lling girder pull bar 100, upper trave lling girder pull bar 100 upper ends and upper trave lling girder are hinged, and lower end and tooth bar 98 connect firmly.Gear 97 and tooth bar 98 engagements, connect firmly gear rocking arm 107 on gear, one end and gear rocking arm 107 other ends of cylinder II 108 piston rods are hinged.Cylinder body and bearing pin II 109 are hinged.Centered by the right-angle line intersection point at the B angle of framework platform 62, rotating shaft 103 is set, rotating shaft 103 centers overlap with right-angle line intersection point and connect firmly on framework platform 62.Centered by the right-angle line intersection point at the A angle of bending turnover panel 104, axle sleeve 102 is set, axle sleeve 102 centers overlap with right-angle line intersection point and connect firmly on bending turnover panel 104.Axle sleeve 102 is arranged in rotating shaft 103, rotating shaft cover 102 and rotating shaft 103 matched in clearance.Bending turnover panel 104 overlaps 102 103 rotations around the shaft by rotating shaft.Piston rod one end and the bending turnover panel 104 of cylinder I 105 are hinged, and cylinder body and bearing pin I 106 are hinged.
The course of work: framework platform 62 is placed after sheet material 45 above, stretch out forward the part that needs bending, under 108 effects of cylinder II, gear rocking arm 107 driven gear 97 rotation that moves up, gear 97 is stirred tooth bar and is moved down and drive trave lling girder pull bar 100 also to move down, and in drives, trave lling girder 92, forming cutter 93 move down compression sheet material 45.The plane of bending turnover panel 104 corresponding sheet materials is rotated around the shaft to sheet material 45 upwards bendings.Bending exhaust hood I 105, cylinder II 108 set back, the equal return of each assembly.The workpiece of bending is taken out.That is: Pneumatic reverse turning bed bender is the set of gears by being driven by cylinder II 108, the transmission mechanism of tooth bar, trave lling girder 92 is moved up and down, and make forming cutter on trave lling girder 92 compress sheet material, the be limited inclined plane of the maximum bending angle of panel of forming cutter 93 upper surfaces; By cylinder I 105, make plane 103 rotations around the shaft of turnover panel 104 corresponding sheet materials to sheet material 95 upwards bendings, realize the unidirectional bending of sheet material.
Existing manual turnover panel bender, its basic structure is with identical with above-mentioned Pneumatic reverse turning bed bender to the wrap direction of sheet material; The moving up and down of trave lling girder on it, the rotation around the shaft of the plane of the corresponding sheet material of turnover panel, all completes manually.
By the introduction of above three kinds of bender Forging Process, can recognize that equipment is all to direction bending of sheet material, and above three kinds of equipment are due to structural limitations, also cannot be by two cover bending structures be installed, dog leg is carried out in realization in the situation that not stirring sheet material, as Z-shaped in sheet material being converted in the situation that not stirring sheet material.
There is following problem in the said equipment and processing method:
If it is Z-shaped that 1 sheet material requires to be converted into, operator needs feeding repeatedly, the bending material returned, turn-over, feeding, then bending.When batch production, the more difficult control of uniformity of size.And labor strength is large, is unfavorable for physical and mental health.
2, because non-cutting time in production process is too much, cause production efficiency low, production cost increases.
