Five, the specific embodiment
Be described further below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 are the structural representations of manual screw jack bending machine.Fan-shaped positioner 1, pointer 8, curved boom 13 and screw jack 14 by pivoted arm 4, band dial 9 are formed; Be equipped with groove runner 2 near pivoted arm 4 outer ends, at the alignment pin 6 that the pivoted arm middle part is equipped with, pivoted arm 4 fixedlyed connected with fan-shaped positioner 1, the ejector pin 5 at middle part flexibly connects with the suspension ring of push rod 12 upper ends of jack 14 18.Near pivoted arm 4 the inners, be equipped with main shaft 7, this 7 by front and back successively with pin 8, the band dial 9 fan-shaped positioner 1, pivoted arm 4 and curved boom 13 be chained together.Pointer 8 is fixedlyed connected with main shaft 7 front ends, and fan-shaped positioner 1 thereafter and pivoted arm 4 are the flexible connections that are enclosed within on the main shaft 7, fixedlys connected with main shaft 7 rear ends in the top of last curved boom 13.Be equipped with channel shaped runner 10 at the middle part of curved boom 13.The curved edge of fan-shaped positioner 1 is provided with deep-slotted chip breaker, and runner 10 coexists in the plane on runner 2 on the plane of fan-shaped positioner 1 and the pivoted arm 4 and the curved boom 13.Can be according to the difference that bends the pipe fitting diameter, select to change the fan-shaped positioner 1 of different size, simultaneously should mobile runner 2,10 on pivoted arm 4 and the curved boom 13 corresponding position of mounting hole.According to place, power source and need of work situation, bending machine is optional manual or electronic, also can select the screw jack 14 or the hydraulic jack 19 of multi-series for use; Fig. 3 is the bending machine that adopts electric screw-jacks 14, and its structure has only increased motor 20 and worm reduction gear 21 with the same with manual screw jack bending machine, drives ratchet group 17 by reductor 21 output shafts and drives jack 14 work.Can increase work efficiency.Fig. 4 is the bending machine that adopts hand-hydraulic jack 19.This machine is compared with Fig. 1, bending machine shown in Figure 3, just makes screw jack 14 into hydraulic jack 19, and its cost is lower, and the transmission efficiency height is operated more laborsaving.Fig. 5 is the bending machine that adopts electric hydaulic jack 19, this machine is the same substantially with bending machine shown in Figure 4, motor 20 and worm reduction gear 21 have just been increased, crank mechanism 22 is installed on reductor 21 output shafts, and link to each other with rocking handle and oil pump cylinder-piston 23 on the hydraulic jack 19 with connecting rod, to drive jack 19 work.The vertical rod 24 of curved boom 13 by its underpart is supported and fixed on and keeps flat on the base 11 among the figure.Jack 14,19 usefulness pins 15 are fixed on curved boom 13 bottoms.16 for standing up base, is used for this machine is erected placement, is user-friendly to.
The course of work of electric hydaulic jack bending machine is described below in conjunction with Fig. 5:
According to actual size, use formula earlier
Calculate an arbitrarily angled curved curved spot size; Calculate 90 ° of curved curved spot sizes with formula L-R, in the formula: L-actual size, α-angle of bend, R-bending radius.The computing formula that the existing bending machine of above-mentioned formula is adopted is simple, not only convenience of calculation, and computational accuracy height.On pipe fitting 3, draw good mark then, this moment, bending machine was the carriage return state, pivoted arm 4 outer ends are towards the lower-left, the arc limit of fan-shaped positioner 1 is towards the lower right, this moment is at runner 2,10 and the big space of fan-shaped positioner 1 between insert pipe fitting 3, and put into runner 2,10 and the groove of fan-shaped positioner 1 in, actuating motor 20 then, drive worm reduction gear 21, crank mechanism 22 on reductor 21 output shafts passes through connecting rod; rocking handle makes oil pump cylinder-piston 23 work; promote to move on the push rod 12 of hydraulic jack 19; make pivoted arm 4; the fan-shaped positioner 1 of band dial 9 clockwise rotates synchronously; stop when pointer 8 aligns with 0 scale on the dial 9; after adjusting playing curved some mark and also aim at 0 scale on the dial 9 on the pipe fitting 3; restart motor work, pivoted arm 4 fan-shaped positioners 1 change clockwise, and bottom has runner 10 to stop; there are runner 2 promotions pipe fitting 3 upper ends, and pipe fitting 3 just curves the arc of fan-shaped positioner gradually.As will bending at an angle of 90, parking carriage return when the relative pointer 8 of the scale on the dial 9 will turn over 93 °～95 °, it just in time is 90 ° for 3 °～5 ° that pipe fitting 3 takes out the back resiliences.
