The technical solution of the utility model is: the section bar cold-bending automatic molding equipment, include main top-bearing jar, main hold-down cylinder, left and right hold-down cylinder, left and right charging cylinder, base and be installed in mainframe and left and right frame on the base, wherein main hold-down cylinder and left and right hold-down cylinder are installed in respectively on mainframe and the left and right frame, promote mainframe and left and right frame respectively and make the main top-bearing jar and the left and right charging cylinder of the motion of relative base and be installed on the base.
Angle between the force direction of the force direction of above-mentioned main top-bearing jar and left and right charging cylinder is acute angle or obtuse angle.
The force direction of above-mentioned main top-bearing jar is vertical with the force direction of left and right charging cylinder.
Above-mentioned mainframe and left and right frame are bearing in base by rail plate.
Above-mentioned mainframe, left and right frame, base are many webs box-shaped welded steel structure.
Above-mentioned main top-bearing jar, main hold-down cylinder, left and right hold-down cylinder, left and right charging cylinder all are the integrated structures that sensor, electric-hydraulic proportion inverting element, cylinder body, oil circuit are blended in one.
Above-mentioned left and right charging cylinder promotes left and right gantry motion by SERVO CONTROL.
The utility model is owing to adopt the structure of the many holder combination of multi-cylinder, and fuselage supporting by many webs box-shaped welded steel structure, multi-cylinder of the present utility model is located by SERVO CONTROL, and crooked pressure all can be regulated, and finishes the orderly combination action of each cylinder, realize the accurate automatic forming of various section bar three fulcrum clod washes, section bar cold-bending automatic molding equipment compact conformation of the present utility model, widely applicable, reliable operation, convenient and practical, can satisfy clod wash differential profiles and difform requirement.

The specific embodiment
Embodiment:
The structural representation of multi-cylinder built-up section cold-bending automatic molding equipment of the present utility model as shown in Figure 1, 2, include 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 are installed in respectively on mainframe 4 and the left and right frame 6,2, 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 9 motions of relative base 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 the utility model multi-cylinder built-up section cold-bending automatic molding equipment, 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.
