4) face of weld after the planing is carried out zinc supplementation, the thickness of zinc layer is between 12～16 microns;
5) the seamless rail shaped steel after the zinc supplementation is carried out alignment;
6) the seamless rail shaped steel after the alignment is carried out quick sawing, the hollow cage guide that forms after the quick sawing, its two ends have burr, and its length leaves certain surplus;
7) to the hollow cage guide of two ends band burr according to the rules size carry out essence and cut, and repair burr on the end face, form the hollow cage guide finished product.
Another technical problem to be solved by this invention is: a kind of manufacturing process that is used for the automated production guide rail of closed section type hollow elevator is provided, and this manufacturing process has improved production efficiency greatly.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the described the 1st) to the 6th) go on foot and all on automatic assembly line, finish, the gait of march of this production line is controlled between 20～35 meters/minute.
The invention has the beneficial effects as follows: adopt manufacturing process of the present invention can produce satisfactory guide rail of closed section type hollow elevator, this guide rail of closed section type hollow elevator is compared with original open-type hollow cage guide, further save steel, also strengthened antitorque commentaries on classics deformation ability in the longitudinal direction; But also greatly facilitate the installation of hollow cage guide, and improved the glacing flatness of the spigot surface that a plurality of hollow cage guides of being serially connected form, reduced the elevator running noises.In addition, the employing of automatic production line has improved production efficiency greatly.

The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
Embodiment one:
Preparation before the start: at first, on automatic assembly line, load onto with as described in Figure 2 guide rail of closed section type hollow elevator 1 corresponding many to being rolled into forming roll, galvanized steel is placed on the discharging frame, and with galvanized steel with draw strip by the welding method dock, then, to draw strip and introduce the material stock leading truck from a side of material stock leading truck, draw from the opposite side of material stock leading truck, being clamped in first pair rolls in the flattening roller, regulate the many of synchronous working, make the gait of march of galvanized steel be controlled between 20～35 meters/minute rolling flattening roller and many to being rolled into the velocity of rotation of forming roll;
Start operation then: galvanized steel is under the traction that rolls flattening roller, galvanized steel on the discharging frame constantly entered under the guiding of material stock leading truck manyly flatten rolling flattening roller, too much through the galvanized steel warp that leveling is later to being rolled into rolling of forming roll, make galvanized steel generation deformation, be formed with seam guide rail shaped steel, the gap of the sealing of this guide rail shaped steel is between 0.6～1.0 millimeter, and sealing two side planes shown in Figure 3 are that the depth of parallelism of baseplane 4, sealing left side and baseplane, sealing right side 5 is between ± 0.3 millimeter; There is seam guide rail shaped steel to continue to move ahead, pass and the corresponding radio-frequency induction coil of profile that seam guide rail shaped steel is arranged, the high frequency sun plate voltage that links to each other with radio-frequency induction coil is usually at 8 ± 10% kilovolts, the inboard of radio-frequency induction coil and have between the outer surface of seam guide rail shaped steel and keep 3～4 mm clearance, surface temperature through the seamless rail shaped steel that forms after the high-frequency welding reaches 300～400 ℃ usually, and 1.5 millimeters at the inside top that will guarantee weld seam 2 back side that to exceed its two side plane be left and right side baseplane 4 and 5---and full to guarantee weld seam; Seamless rail shaped steel continues to move ahead, through planing tool the time, the outside of planing tool butt welded seam 2 exceeds the part of left and right side baseplane 4 and 5 planes, after the planing, left and right side baseplane 4 and 5 just forms an even curface with weld seam, and the concavo-convex of this plane is no more than 0.1 millimeter; Then, seamless rail shaped steel after the planing is through the zinc supplementation device in the place ahead the time, the surface temperature of seamless rail shaped steel is between 200～250 ℃, spray gun in the zinc supplementation device carries out zinc supplementation to the outer surface of the weld seam 2 of seamless rail shaped steel, the air pressure of spray gun is controlled between 0.8～0.9MPa, in conjunction with the gait of march of galvanized steel, the transporting velocity by control zinc silk with the THICKNESS CONTROL of zinc layer between 12～16 microns; Seamless rail shaped steel after the zinc supplementation passes through alignment and sawing fast successively, form hollow cage guide, when quick sawing, compare with the size of hollow cage guide finished product, usually leave 30～40 millimeters surplus, the hollow cage guide that sawing is got off rolls off the production line, and with annular saw it is carried out the scale essence then and cuts, and repair deburring, form the hollow cage guide finished product.
Embodiment two:
Just the same with the procedure of processing of embodiment one, different be used for moulding many to being rolled into the forming roll difference, that adopts here is how corresponding with guide rail of closed section type hollow elevator 1 shown in Figure 4 to being rolled into forming roll.
