Description
Technical field
The present invention is a kind of multi-cylinder built-up section cold-bending automatic molding equipment and processing method thereof that is used for boats and ships, building, bridge, pressure vessel and other structural steelwork, belongs to the renovation technique of section bar cold bending equipment and processing method thereof.
Background technology
In recent years, owing to need the member demand of cold bending constantly to increase suddenly, cold bending equipment and technology have obtained fast development, last stage has been experienced manual hot bending, mechanical type section bar hot bending and clod wash, roller type and has rolled the operation methods of operation such as curved, cold bending needs large slide force, so adopt hydraulic-driven mostly and use the numerical control control mode in present stage.On bending forming method, developed following main type at present both at home and abroad:
1, multi-mould shaping clod wash: a plurality of moulds are adjusted into required section bar curve with numerical control method, clamp the section bar two ends then, stretching makes section bar slightly surpass its yield strength limit to section bar with stretching cylinder, drives the mould motion, and generation roof pressure power is carried out cold bending to section bar.This method shortcoming is that investment is big, and equipment is huge, and the volume that takes up space is big, and is not easy to estimate the section bar springback capacity, and section bar reaches the anticipation shape to be needed to revise repeatedly.
2, cold bending piecemeal promptly after one section clod wash, carries out back one section clod wash again after the feeding feeding is finished, be shaped until finishing the whole piece section bar.This operation is simpler relatively, and equipment size greatly reduces, and floor space is little.By its clod wash principle, can be divided into four fulcrum clod washes and three fulcrum clod washes.Four fulcrum clod washes are the both sides of clod wash deformation section, and each two fulcrum has applied symmetrical concentrated force, and the moment of flexure of the arbitrary section in the deformation section is a constant at this moment, and shearing force is zero, is the pure bending state.Pure bending is to adopt four fulcrum structures, so the equipment mechanism complexity, control is had relatively high expectations, and feeding speed is slow, and the crooked principle of concentrated force is then adopted in three fulcrum clod washes, adopts three fulcrum structures, and device structure is simple, control easily, and production efficiency is higher.Therefore, three fulcrum clod wash mechanisms have become the type of main application development both at home and abroad at present, but the shortcoming that existing three fulcrum cold bendings equipment exists is a complex structure, and the accuracy of motion is not good enough, is difficult to satisfy clod wash differential profiles and difform requirement.
Summary of the invention

The specific embodiment
Embodiment:
The structural representation of multi-cylinder built-up section cold-bending automatic molding equipment of the present invention as shown in Figure 1, 2, including main top-bearing jar 10, main hold-down cylinder 3, left and right hold-down cylinder 5,1 and the right side, charging cylinder 7,8, base 9 and be installed in mainframe 4 and left and right frame 6,2 on the base 9) wherein main hold-down cylinder 3 and left and right hold-down cylinder 5,1 be installed in respectively on mainframe 4 and the left and right frame 6,2, and promote mainframe 4 and left and right frame 6,2 respectively and make the main top-bearing jar 10 and the left and right charging cylinder 7,8 of relative base 9 motions and be installed on the base 9.Above-mentioned main top-bearing jar 10, main hold-down cylinder 3, left and right sides hold-down cylinder 5,1 and left and right sides charging cylinder 7,8 are arranged in the scope of base 9, and shared production space is little.
Angle between the force direction of the force direction of above-mentioned main top-bearing jar 10 and left and right charging cylinder 7,8 is acute angle or obtuse angle.In the present embodiment, the force direction of above-mentioned main top-bearing jar 10 is vertical with the force direction of left and right charging cylinder 7,8.
In the present embodiment, above-mentioned mainframe 4 and left and right frame 6,2 are bearing in base 9 by rail plate.Above-mentioned mainframe 4, base 9 and left and right frame 6,2 are many webs box-shaped welded steel structure.The fuselage good rigidly that many webs box-shaped welded steel structure is formed, mechanism's compactness, the huge pushing force that produces when bearing cold bending.
In the present embodiment, above-mentioned main top-bearing jar 10, main hold-down cylinder 3, left and right hold-down cylinder 5,1 and left and right charging cylinder 7,8 all are the integrated structures that sensor, electric-hydraulic proportion inverting element, cylinder body, oil circuit are blended in one.
The processing method of multi-cylinder built-up section cold-bending automatic molding equipment of the present invention, it comprises the steps:
1) section bar is placed left and right hold-down cylinder 5,1 below, according to the cold bending process requirement, determine the position of 2 side compression points by one of them feed motion in the left and right charging cylinder 7,8, left and right then hold-down cylinder 5,1 clamps section bar;
2) main subsequently hold-down cylinder 3 is also depressed the main bending point that clamps section bar;
3) carry out feed motion according to main top-bearing jar 10, promote main support 4 motions, and, finished the pressurize operation of crooked stroke of feeding and bending force by technological requirement the section bar application of force;
4) behind the end of run, promptly realized the bending of the first segment type material;
5) repeat above-mentioned action and then finish the automatic clod wash operation of holotype material piecemeal.
Above-mentioned left and right charging cylinder 7,8 promotes left and right frame 6,2 motions by SERVO CONTROL.By SERVO CONTROL, finish accurate operation.
Above-mentioned steps 1) three kinds of feeding styles are arranged:
1) feeding separately: the side-to-side movement behind left hold-down cylinder 6 workpiece pressings of left feeding cylinder 7, this moment, right charging cylinder 8 unclamped, and is same, and right charging cylinder 8 also can be done similar independent feeding action; Above-mentioned left and right feeding cylinder the 7, the 8th by electron hydraulic proportional servo control, moves back and forth about generation respectively, drives left and right frame 6,2 motions simultaneously.When left hold-down cylinder 6 clamped section bar, right hold-down cylinder 1 unclamped, and drove left frame 6 reciprocating actions by left feeding cylinder 7, had promptly realized the independent left and right sides feeding feeding of left frame 6, otherwise, also can realize the left and right sides feeding feeding of right frame 2.
2) twin-tub friction feeding: after promptly above-mentioned left feeding cylinder 7 was finished feeding action, right feeding cylinder 8 then moved feeding action again, and at this moment, left hold-down cylinder 5 unclamps, and left feeding cylinder 7 is done homing action; Above-mentioned left and right feeding cylinder carries out equidirectional feeding action in turn, then feeding campaign be continuous and about the high speed feeding.
3) the synchronous feeding of twin-tub: promptly left feeding cylinder 7 and right 8 whiles of charging cylinder, equidirectional feeding.
All can adjusting of the stroke (step-length) of the above-mentioned each feeding of frame apart from length and direction, the position of two fulcrums when being the left and right sides hold-down cylinder clamping section bar on the frame of the left and right sides is arbitrarily, thereby, very adapt to three fulcrum cold bending processes neatly, reach the purpose that section bar accurately is shaped.
