Provide embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in drawings, the utility model has a upset oil cylinder 16, upset piston 15 and upset pull bar 18, at upset oil cylinder 16 left ends the upset piston is installed and is equipped with mother 14 and upset oil cylinder cover 13, corresponding upset oil cylinder 16 right end position are equipped with upset end floor beam 6 on upset pull bar 18, upset crossbeam copper sheathing 17 is housed therebetween, on upset oil cylinder 16 and upset end floor beam 6, be fixed with by shaking picker bar 2, shake fiery carriage 3, shake fiery swing arm 4, shake the heater-driven mechanism that fiery roller 7 constitutes, left end and upper right quarter at upset oil cylinder 16 have a upset oil return pipe 1 and upset high-pressure oil pipe 5 respectively, right part at upset pull bar 18 is set with levelling piston rod 21, on levelling piston rod 21, be equipped with and push away protruding oil cylinder 20 and levelling end cross beam 9 is housed by levelling cross beam copper bush 19, be useful on the protruding pulling block 8 that pushes away of placing levelling device by being threaded at levelling piston rod 21 left ends, the upper left quarter and the right-hand member that push away protruding oil cylinder 20 have one to push away protruding return oil pipe 10 and eject oil pipe 11 respectively, push away the levelling spare nut 23 that protruding oil cylinder 20 right-hand members are equipped with levelling oil cylinder lid 22 and tighten together with upset pull bar 18 right-hand members, on said upset end floor beam 6 and the levelling end cross beam 9 drift 12 is housed respectively, flange of rail bolt 34 and nut 25 and tread bolt.This soldering apparatus also has a levelling device main body 30, two bale handles 26 and chucking lug 26A are arranged on levelling device 30 main bodys, top blade 29 is installed on levelling device main body 30, broadsword sheet 35 and by shear bar 34, the bed plate that bed plate handle 36 and blade hold-down screw 33 constitute, by hold-down screw 37 broadsword slideway 31 is installed at levelling device main body 30 middle parts, the broadsword seat slide block 27 that a through hole is arranged in the middle part of being placed with on the broadsword slideway 31, at 35 liang of side positions of levelling device main body 30 corresponding broadswords withdrawing handle 28 on the broadsword is installed, the bottom of last withdrawing handle 28 is inserted in the through hole on the broadsword seat slide block 27, withdrawing handle 28 bottom positions have a spring base on correspondence on the levelling device main body 30, back-moving spring 38 is installed in this spring base, on back-moving spring 38, be connected with broadsword alignment pin 32, retraction mechanism on the formation.
When real work, the rail after diffusing is put into upset end floor beam 6 and levelling end cross beam 9, by 5 oilings of upset high-pressure oil pipe, promote upset pitch brace 18 and be moved to the left, upset end floor beam 6 moves right simultaneously.Be accompanied by the powerful pulling force that manually hits rail and this machine, rail breach two sections distance is dwindled gradually, the last close card of two rails section, utilize heater to give the heating of rail two section parts again, when the temperature at rail profile place is raised to the plasticity temperature, improve the hydraulic coupling of this machine, make the free mutually infiltration of metallic molecule at rail profile place, rail two sections are really combined together.Because the effect of this machine upset, can extrude exoncoma in the commissure, levelling device 30 is contained in pushes away on the protruding pulling block 8 again, and move withdrawing handle 28 downwards, slide block 27 pin 32 that is positioned is blocked, carry out upper slitter.The conversion oil circuit pushes away protrudingly, and levelling piston rod 21 is moved to the left, drive levelling device 30 and be moved to the left, the fuel tap conversion is by pushing away protruding return oil pipe 10 oilings, levelling device is moved right, thereby exoncoma is turned down, treat that the temperature of commissure is reduced to below 500 ℃, pull on earlier withdrawing handle 28 forward, handle 28 to equal with levelling device main body 30, is upwards lifted again in alignment pin 32 tops, carry out withdrawing, unload this bonding machine again, all diffuse welding process and finish.
