Abstract
The utility model relates to a hydraulic shaped bender. A work table is provided with a hydraulic mechanism. The utility model is characterized in that the utility model is also provided with two driving shafts 7, driving wheel discs 6 arranged on the driving shafts, a fixing shaft 3 and an integrated positioning disc 2 arranged on the fixing shaft. Two driving shafts 7 are connected with a hydraulic cylinder, the fixing shaft 3 is arranged on the central vertical line of the two driving shafts 7, and the integrated positioning disc 2 is composed of a middle fixing disc 15 and movable clamping discs 16 on both sides. The utility model has the advantages of no corrugation of the workpiece surface, smooth forming surface, inosculation, easy production of the mould, low cost, simple structure, reliable operation, and convenient operation and disassembly, and the utility model can satisfy the bending of the similar type workpiece.
Description
The utility model belongs to machinery manufacturing technology field, is specifically related to a kind of shaped by fluid pressure that uses to the device that channel-section steel bends, and is widely used in the workpiece processing and fabricating of automobile and similar shape.
At present; the domestic special equipment that does not also have the moulding of bending technology for the bending of the workpiece of specific (special) requirements, can only lean on clod wash and hot bending folding; this is also possible to the not high workpiece of dimension precision requirement; but for the dimension precision requirement height, and require the special bending workpiece of bending no wrinkle, for example automobile fender bracket etc.; preceding two kinds of methods are impossible realize; success is one once in a while, and its scrappage is higher, and cost is very big.Therefore, clod wash and hot bending satisfy the demand to bending at present inadequately.
The purpose of present technique is at having the incompatibility situation that the bending technology requires special bending now, a kind of shaped by fluid pressure bending device is provided, utilize the corner crimping machine hydraulic principle, and integrated positioning dish and active wheel disc are installed on equipment, realize the flawless bending forming of special workpiece no wrinkle with this.
This apparatus structure is as follows:
This device has utilized existing corner crimping machine shaped by fluid pressure principle, comprises workbench, a cover hydraulic mechanism, two driving shafts and the active wheel disc of go up installing thereof, a fixed axis with and go up the integrated positioning dish of installing.Two driving shafts link to each other with hydraulic mechanism, and fixed axis is positioned on the vertical line at two driving shaft line centers, and promptly two driving shafts and fixed axis are equidistant.The integrated positioning dish is combined by three dishes, the fixed disk in the middle of dividing and the chuck on both sides, and they are combined by spiral pin, and fixed disk is a convex, can just in time workpiece be stuck in the combination order.Telophragma maintains static during work, plays the role of positioning, and by both sides chuck pressure stroke fixation workpiece, controls bending forming with hydraulic pressure.The profile of integrated positioning dish should be processed into identical by bending workpiece shape, two initiatively the face of wheel disc cramping workpiece should mill into a plane, during as hydraulic pressure to the workpiece positioning support.
Add man-hour, earlier workpiece is put between two active wheel discs and the integrated positioning dish, primer fluid compresses switch, the integrated positioning dish maintains static, and two active wheel discs of lower end promote piston oil-cylinder through motor and move upward by hydraulic system, the press-bending workpiece, to certain position, bending forming is just finished, and so just obtains preestablishing the bending workpiece of shape.
The advantage of this device is:
1. utilize hydraulic pressure bending device processing work, the wrinkle resistant line of surface of the work, forming surface is smooth, and coincide.
2. mould, promptly initiatively wheel disc and integrated positioning dish are easy to manufacture, and cost is not high.
Simple in structure, the reliable operation of mould, be convenient to operation, convenient disassembly, can satisfy the bending of workpiece of the same type.
Below in conjunction with drawings and Examples this device is elaborated:
Fig. 1 is this shaped by fluid pressure bending device structure diagram.
Fig. 2 is an integrated positioning dish structure chart.
Embodiment: referring to Fig. 1, this device is supporting with workbench 1, and the oil cylinder 8 of hydraulic mechanism connects two driving shafts 7, and two active wheel discs 6 are installed on the driving shaft 7, and initiatively the face of wheel disc 6 cramping workpiece 5 is a plane.The center vertical line of two driving shafts, 7 lines is provided with fixed axis 2, and an integrated positioning dish 2 is installed on it, and this integrated positioning dish 2 is processed into and the consistent shape of the required shape that is processed into of workpiece in advance.The structure of integrated positioning dish 2 is referring to Fig. 2, and it is made of the fixed disk 15 of a middle convex and the chuck 16 on both sides, and is fastening by bolt 4.
The hydraulic mechanism of this device is a prior art, is made of motor 14, pump 13, motor 12, flow speed control valve 11, magnetic valve 10, fuel tank 9, oil cylinder 8 etc., and this mechanism is the electric-controlled switch form, and solenoid directional control valve 10 gets the working condition of electric situation decision executive component.Hydraulic control one-way valve carries out pressurize to active wheel disc oil cylinder 8, and flow speed control valve 11 is used to regulate the initiatively rising or falling speed of wheel disc oil cylinder 8.The native system working media is the 32# antiwear hydraulic oil, is filled with the hydraulic oil of cleaning and injected certain fluid from the motor drain tap in fuel tank by air filter.
