Description

The multidirectional forging press of blower fan main shaft
Technical field
The utility model relates to a kind of improvement of macrotype axes series spare milling train, specifically a kind of multidirectional forging press of blower fan main shaft that forges and presses simultaneously from four direction.Mainly be applicable to the forging of blower fan main shaft.
Background technology
Wind energy is a kind of inexhaustible green energy resource, analyzes about 1,300 hundred million kilowatts of global wind energy total amount according to statistics.The theoretical reserves of China's wind energy are 32.26 hundred million kilowatts.Wind energy mainly concentrates on the contraction area in coastal and open continent, can set up wind farm in these areas.At present, just to increase the development of 35% speed year, China has also formulated the plan of greatly developing wind-power electricity generation to global wind power generation.At present, the factor of restriction wind-driven generator development mainly is the manufacturing technology of blower fan main shaft and canine tooth roller box, and wherein blower fan main shaft is a critical component, because the volume and weight of blower fan main shaft is bigger, high to its specification requirement and reliability requirement, so manufacture difficulty is bigger.In order to improve the quality of production of main shaft, must maintain strict control over each production link.The production link of blower fan main shaft comprises steel ingot heating, forging, quenching, sandblast, sprays paint, detection etc.Described forging be exactly steel ingot with cylindricality in heating furnace, be heated to temperature required after, place on the workbench of forging press and forge and press, by forging and pressing, make steel ingot progressively attenuate, elongated, until needed shape.Present employed forging press comprises that frame, hydraulic cylinder, vertical lift bar, forging and pressing head, workbench constitute, and hydraulic cylinder is fixed on the frame, and the forging and pressing head is connected on the vertical lift bar, and the piston rod of vertical lift bar and hydraulic cylinder connects as one.In the forging and pressing process, the forging of heating need be placed on the workbench, the primer fluid pressing system, the forging and pressing head presses down, forging press forging to heating, make the forging of heating elongated in the horizontal direction, broaden, and then the forging upset 45-90 degree of heating is broken again, by repeatedly forging and pressing, repeatedly upset ability forging molding.The deficiency of this forging press is: the one, and forging forming speed is slow, and production efficiency is low, owing to blower fan main shaft slightly weighs, volume is big, so needed time of every forging forming is longer; The 2nd, the energy consumption height; The 3rd since at above-below direction to when forging and pressing, metal is in the process of plastic deformation, its flowability will be subjected to the influence of many places corner, makes metal produce flow blind angle and the incomplete problem of stagnant zone mold filling, therefore can produce substandard products or waste product.
Summary of the invention
The purpose of this utility model is to provide a kind of multidirectional forging press of blower fan main shaft that can help improving blower fan main shaft forging forming speed, enhance productivity, cut down the consumption of energy, reduce substandard products or waste product.
For reaching above purpose, the technical scheme that the utility model adopted is: the multidirectional forging press of this blower fan main shaft, comprise frame, hydraulic cylinder, the vertical lift bar, the forging and pressing head, workbench constitutes, hydraulic cylinder is fixed on the frame, the forging and pressing head is movably connected in the lower end of vertical lift bar, the piston rod of vertical lift bar and hydraulic cylinder connects as one, it is characterized in that being provided with a left side in the bottom of frame, right horizontal hydraulic cylinder, on a left side, the piston rod end of right horizontal hydraulic cylinder is provided with fixing level forging and pressing head, a left side, the piston rod of right horizontal hydraulic cylinder and the piston rod synchronization telescope of hydraulic cylinder are to forging.
The utility model is also implemented by following measure: the pipeline of described left and right horizontal hydraulic cylinder is connected with same hydraulic pump with the pipeline of hydraulic cylinder, and is flexible by same hydraulic pump drive, holds at the seat of left and right horizontal hydraulic cylinder to be provided with holder; The width of described level forging and pressing head is than the little 5-10cm of diameter of blower fan main shaft; The piston rod axle center height of left and right horizontal hydraulic cylinder is consistent with forging axle center height.
The beneficial effects of the utility model are: with at present in the blower fan main shaft manufacture process employed forging press compare, owing to adopted from four direction and simultaneously forging forged and pressed, and the pressure unanimity, so forging forming speed is fast, production efficiency is high, the needed time is short, energy consumption is low, yield rate is high for one of every forging forming.
Description of drawings
Fig. 1, be structure front-view schematic diagram of the present utility model.
The specific embodiment
Make the utility model with reference to Fig. 1.The multidirectional forging press of this blower fan main shaft, comprise frame 1, hydraulic cylinder 2, vertical lift bar 3, forging and pressing 4, workbench 11 constitutes, hydraulic cylinder 2 is fixed on the frame 1, forging and pressing 4 are movably connected in the lower end of vertical lift bar 3, vertical lift bar 3 connects as one with the piston rod of hydraulic cylinder 2, forging and pressing by forging and pressing 4 a realization downward direction, simultaneously, 11 pairs of forging of workbench produce reaction force, thereby on having realized, the relative forging and pressing of following both direction, forging is extended upward with right and left in the longitudinal direction, it is characterized in that being provided with a left side in the bottom of frame 1, right horizontal hydraulic cylinder 5,6, on a left side, right horizontal hydraulic cylinder 5,6 piston rod end is provided with fixing level forging and pressing 7,8, a left side, right horizontal hydraulic cylinder 5, the piston rod synchronization telescope of 6 piston rod and hydraulic cylinder 2, by a left side, right horizontal hydraulic cylinder 5, the level of 6 piston rod ends forging and pressing 7,8 realize from the forging left and right directions to forging, stop forging last, the left side that following both direction the time is produced forging and pressing, extension on the right, thereby force forging to extend to the length direction of forging, and square flanging appears, again to forging upset 45 degree, to the square flanging place of forging to forging, then become 8 limit shapes, rotate 22.5 degree again, 8 limit shape flangings of forging are closed on the limit to forging, then become 12 limits, rotate 45 degree again, to 12 limit shape flangings of forging every on one side to forging, then become 16 limits, until becoming cylinder.
The pipeline of described left and right horizontal hydraulic cylinder 5,6 is connected with same hydraulic pump 9 with the pipeline of hydraulic cylinder 2, drive flexible by same hydraulic pump 9, thereby realize forging is forged and pressed synchronously from four direction, and the pressure unanimity, be provided with holder 10 at the seat end of left and right horizontal hydraulic cylinder 5,6; The width of described level forging and pressing 7,8 is than the little 5-10cm of diameter of blower fan main shaft; The piston rod axle center height of left and right horizontal hydraulic cylinder 5,6 is consistent with forging axle center height.
