Abstract
The invention discloses a pressure flat bending device which comprises a baseplate, a triangular plate fixedly connected on the upper surface of the baseplate, and a guide plate movably connected on the front surface of the triangular plate. The front surface of the triangular plate is perpendicular to the baseplate, a slider is movably connected below the guide plate, the lower surface of the guide plate and the upper surface of the slider incline towards the direction of the triangular plate, and a template is arranged on the lower surface of the slider. The guide plate and the slider are in inclination contact, and a to-be-bent steel batten or angle bar and flat-bulb steel are stressed by bending force in the horizontal and outward direction and by force in the vertical and downward direction, so that the to-be-bent steel batten or angle bar and the flat-bulb steel are prevented from wrinkling and deforming. Since the whole bending process is a pure physical process and a crystal structure of the to-be-bent steel batten is not changed, no damage is caused to base metal.
Description
Technical field
The present invention relates to the flat bending apparatus of a kind of pressure, belong to curved steel bending tool field.
Background technology
In the manufacturing process of steel construction, often having many steel plate strip or shaped steel needs flatly to curve various shape, or bending steel plate strip needs aligning.Existing bending techniques to steel plate strip put down curved, aligning be all adopt firer with dry rifle steel plate is heated, the characteristic utilizing steel to expand with heat and contract with cold carry out flat curved or align.This method cost is high, efficiency is low, and has certain infringement to mother metal, affects quality.
As bending by forcing press routine, steel plate strip is little with flat contact surface, erects shakiness, easy torsional deformation after steel plate strip vertical level pressurized.
Summary of the invention
Goal of the invention: the present invention proposes the flat bending apparatus of a kind of pressure, this device is indeformable wrinkle resistant when carrying out bending or aligning.
Technical scheme: the technical solution used in the present invention is the flat bending apparatus of a kind of pressure, comprise base plate, be fixedly connected on the set square of plate upper surface and the road that is movably connected on set square front surface to plate, described set square front surface is perpendicular to base plate; Below in from described road to plate is also connected with slide block, and described road all tilts towards set square direction to plate lower surface and slide block upper surface; Described slide block lower surface is provided with template.
As a modification of the present invention, described flexible connection for being slidably connected, and is the guide rail groove structure matched.Described road to plate lower surface and slide block upper surface all horizontal by 45 degree of angles.
As another improvement of the present invention, described base plate is provided with via-hole array, via-hole array there is also mounted the locating piece be made up of alignment pin and resist printing piece.
Beneficial effect: the flat bending apparatus of pressure proposed by the invention, by adopting contact of incline plane in road between plate and slide block, making steel plate strip to be curved or shaped steel not only be subject to level and bending outwards power, also receive simultaneously one vertical under power, prevent its wrinkling deformation.Again because whole BENDING PROCESS is pure physical process, do not change the crystal structure of the material of steel plate strip to be curved own, so do not damage mother metal yet.
Accompanying drawing explanation
Fig. 1 is the structural representation of base plate in the present invention;
Fig. 2 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to various equivalents of the present invention has all fallen within the application's claims limited range.
Alleged " front ", " front " in claims, description and Figure of description, " front side " refer to along the direction of base plate 1 away from set square.
As shown in Figure 1, base plate 1 is the steel plate of one piece of horizontal positioned, as basis and the support of whole device.Base plate 1 is provided with via-hole array, and via-hole array is made up of regularly arranged multiple through holes 2, and the distance of adjacent through-holes 2 is equal.Via-hole array is distributed in base plate 1 both sides.
As shown in Figure 2, base plate 1 is provided with set square 3, the front surface of this set square 3 is a smooth plane and perpendicular to base plate 1.Set square 3 front surface and road are slidably connected to plate 4 rear surface, make to slide up and down along set square 3 front surface to plate 4.Road is level to plate 4 upper surface and is connected with press, and press applies a downward power to road to plate 4 upper surface.Road is the inclined-plane of a set square 3 direction inclination towards the rear 45 degree to plate 4 lower surface.Suitable to plate 4 lower surface with road, the upper surface of slide block 5 is also for set square 3 towards the rear tilts the inclined-plane of 45 degree.Clamping plate 7 are provided with to plate 4 lower surface and slide block 5 upper surface in road.These clamping plate 7 are divided into groove and guide rail two parts, and groove part is arranged on the lower surface tilted to plate 4, and rail sections is arranged on slide block 5 upper surface.So generally, slide block 5 can slide along the clamping plate of inclination 45 degree to set square 3 direction under self gravitation effect, and is finally close to set square 3 front surface.
Described slide block 5 lower surface is provided with template 6, and this template 6 just aims at the bending position of steel plate strip to be curved, and other parts of slide block 5 lower surface are parallel to base plate 1.Base plate 1 both sides are dispersed with the via-hole array be made up of multiple through hole 2 as previously mentioned.During use, the two ends of steel plate strip to be curved need to be fixed on base plate 1 by locating piece, and described locating piece is made up of alignment pin 8 and resist printing piece 9.Select the through hole 2 that steel plate strip two to be curved brings out, in this through hole 2, insert alignment pin 8, and expose at alignment pin 8 and load onto resist printing piece 9 with the end of base plate 1 upper surface.Steel plate strip to be curved two ends are fixed by two locating pieces respectively.
Described in front, press applies a downward power to road to plate 4 upper surface, and this is tried hard to recommend dynamic road and together moves down along the front surface of set square 3 to plate 4 and slide block 5.When the template 6 of slide block 5 lower surface touches base plate 1, base plate 1 applies a power upwards to slide block 5.According to force resolution principle, road applies the power perpendicular to slide block 5 upper surface to slide block 5 to plate 4, this power resolves into horizontal forward power and downward power, power partial offset upwards that bottom plate 1 applies to slide block 5 this downward power of decomposing out and the gravity of slide block 5 own.So slide block 5 is under above-mentioned decomposition horizontal forward power effect out, can moves forward and by template 6, steel plate strip to be curved be bent, and the downward power compression from the top down steel plate strip to be curved out of above-mentioned decomposition simultaneously.Existing bending machine applies the power of a bending direction only to steel plate strip to be curved, makes steel plate strip to be curved easy in the vertical direction in BENDING PROCESS wrinkling.And steel plate strip to be curved is not only subject to described decomposition horizontal forward power out in the present embodiment, be also subject to the downward power that top slide block 5 applies, therefore the present embodiment effectively can eliminate the wrinkling in bend pipe process simultaneously.Again because whole bend pipe process is pure physical process, do not change the crystal structure of the material of steel plate strip to be curved own, so do not damage mother metal yet.
