Five, the specific embodiment
Describe below in conjunction with the just concrete real-time mode of accompanying drawing.
Shown in Figure 1, a kind of typical Wedge blade product, shape is comparatively complicated, and curved surface is curved.The position that curved surface is the thickest is that 8mm, the thinnest position are 1.2mm.The processing of leaves process is to adopt the rolling curved surface variable wall thickness vane of rolling formation apparatus on the 6300KN hydraulic press, 45 steel plates with uniform thickness are blank, by rolling formation apparatus blank is rolled into the plate wedge material, about blank heating to 1000～1100 ℃, through one rolling operation direct forming.The concrete manufacturing process of Wedge blade has:
Blank → heating (1000 ℃) → roll is rubbed with the hands and is rolled → shot blasting on surface → sandbag grinding.Obtain finished product through ground finished.
Shown in Figure 2, be the transmission mechanism schematic diagram that a kind of variable wall thickness vane is made rolling formation apparatus; Above-described roll stranding is rolled operation and is finished by the rolling formation apparatus that is installed in hydraulic press, rolling formation apparatus is pumped by hydraulic press 1 piston and slide block 2, through crank 3, connecting rod 4 mechanism driving, and driving the positive and negative rotation of two rolls, the blank of blade is rubbed with the hands by roll at two roll shop buildings and is rolled into shape.
Fig. 3 and shown in Figure 4, a kind of variable wall thickness vane is made rolling formation apparatus.It comprises cope match-plate pattern 5, die shoe 6, twisted seat 7, connecting rod 4, bearing pin 8, two rolls 9 and support plates 10; Twisted seat is linked together by bolt below cope match-plate pattern, and with twisted seat and connecting rod, connecting rod is connected with crank by bearing pin, and crank is loaded on the roll two ends, and two rolls are contained on two support plates, and two support plates are by being bolted on the die shoe; The circumference of each roll is provided with the type groove identical with blade profile and curve form, and the type groove on two rolls has constituted closed die groove.Rolling formation apparatus is in assembling with when not working, and is provided with two between cope match-plate pattern and the support plate and is connected bracing frame, and bracing frame is made up of pillar 11 and bearing 12.During use with bolt respectively on cope match-plate pattern and support plate.
Fig. 5 and shown in Figure 6, roll type groove.Type groove 901 is uniform along the roll circumference direction, and the lateral dimension of type groove equals the length of the body of roll.
Roll two ends symmetry is equipped with two cover crank and connecting rods, and the roll two ends are that symmetry is stressed.The roller head at roll two ends is triangular in shape, directly makes triangle key 902, and crank is enclosed within on the triangle key roller head, and is limited by bolt and end cap.
Roll is provided with three type grooves 901, by the conversion of roller head triangle key 902, transfers roll work type groove.By the triangular key application of force, increase torsional strength, three passes also being convenient on the roll simultaneously arbitrarily exchange, and prolong roll campaign.
By changing crank and connecting rod geometrical length, two rolls form speed difference, can change the metal flow speed of blank surfaces externally and internally,, realize that stranding rolls into shape, produces curved section bar.
By the eccentric bushing of adorning between support plate and the roll 13.Regulate two roller gaps, adjust the centre-to-centre spacing of roll.
The cope match-plate pattern that a kind of variable wall thickness vane is made rolling formation apparatus links to each other with the top shoe of hydraulic press by briquetting, transmits power drive by the top shoe of hydraulic press; Two support plates are fixed on the die shoe, die shoe by pressing plate fixer press on workbench.
It is motive power with the hydraulic press that a kind of variable wall thickness vane of the utility model is made rolling formation apparatus, does pumping by slider of hydraulic press drive cope match-plate pattern, through the transmission of crank linkage, is converted into the positive and negative rotation of roll.In the type groove between two rolls of blank, two rolls rotate on the contrary, and roll directly contacts with rolled piece, force metal to produce plastic deformation, and making the disposable extrusion molding of blank is blade.The rotating speed of two rolls is by the downstream rate decision of hydraulic press, and the speed of regulator solution press can be regulated the mill speed parameter of roll.
A kind of variable wall thickness vane of the utility model is made rolling formation apparatus and obviously is different from traditional rolling mill and forging roll, it is simple in structure, do not need power sources such as motor, only be mounted on the general hydraulic press, significantly reduced the equipment input, shorten the production cycle, improved production efficiency and stock utilization, the rate of reducing the number of rejects and seconds.
Along with the development of navigation, Aeronautics and Astronautics device, complex-shaped change wall thickness part uses more and more wider, and more and more, the utility model can be widely used.
