Abstract
The invention relates to a method for processing a winding drum of a pulling reel, which overcomes the defects that the prior processing method has poor coaxiality so as to make the mounting difficult, an externally-supported shaft neck at the shaft end of the winding drum and a winding drum body have large radial jittering, the processing accuracy of the winding drum is difficult to ensure, and the like. The invention adopts a method for improving the processing accuracy of the winding drum of the pulling reel, which comprises the following steps: processing the outer circular surface of a blank fanning strip and a blank hollow shaft which are subjected to heat treatment and the parts of a blank pyramid shaft provided with gears and bearings to surplus amount which is 2 to 5 millimeters from the set value respectively, processing the rest parts and a hooked plate and a positioning disk of the winding drum to the set value respectively; grinding a sloping table board contacted with fanning strip and the pyramid shaft to a matched shape; assembling the processed parts of the winding drum; detecting the radial jittering condition of the surplus amount parts by a dial test indicator; integrally processing the parts to the set value by a heavy machine tool; and detecting and checking the winding drum. The method greatly reduces the ellipticity of the hollow shaft, the pyramid shaft and a core shaft of the winding drum and the radial jittering amplitude, and improves the reeling speed and the quality of strip coil.
Description
Technical field
The present invention relates to a kind of machining process, specifically belong to the method for machine tensions coiler mandrel.
Background technology
Pull reel is the visual plant on cold rolling, the hot-rolled strip production line, and it plays a part to support or the collecting belt steel, regulate rolling tensile force.Reel is a core component wherein, and it is made of parts such as hollow shaft, pyramid axle, fanning strip, gib head plate, positioning disk, outer supporting member, rotation contract cylinders.The accuracy of manufacture of reel has direct influence to the belt steel product quality, reel precision height, and the belt steel rolling tension fluctuation is little, and unit operation is steady, and is little to the influence of coil of strip core band steel quality, rolled products lumber recovery height; Otherwise the reel accuracy of manufacture is low, and ovality is big, and axle head is beated greatly, must cause the reel operation uneven.The excessive reel of ovality is in working order the time, because fan-shaped edges of boards perk causes the coil of strip internal layer to produce impression, the roll coil of strip is loosed core during coil stripping, has a strong impact on band coil of strip quality.This situation is especially obvious in speed height, coiler mandrel performance in service that tension force is big.In traditional reel is made, generally be earlier blank fanning strip after the heat treatment and pyramid axle to be combined by frock, reprocessing fanning strip cylindrical, the correlation that then reel each several part part is connect according to them is assembled into complete reel.But owing to often be subjected to the influence of hollow shaft, pyramid axle, fanning strip processing and assembly precision, outer spring bearing position accomplishes that coaxial line installs very difficulty on reel mandrel periphery that makes the position of the bearing installed on the hollow shaft and gear, is made up of pyramid axle and fanning strip and the pyramid axle, thereby cause the reel axle head to support axle journal outward and produce circular runout, spool body also produces big ovality and circular runout, makes the machining accuracy of reel be difficult to assurance and influence product quality and qualification rate.
Summary of the invention
The objective of the invention is to: overcome the deficiencies in the prior art, the method that provides a kind of machining accuracy, assurance crudy, raising that can improve reel to batch the mandrel process precision of tension reel of steel sheet product qualification rate.
Realize the technical measures of above-mentioned purpose:
A kind of method that improves mandrel process precision of tension reel, its step:
1) position of installation gear and bearing is respectively machined to from the surplus amount that sets value 2～5 millimeters on periphery, blank hollow shaft and the blank pyramid axle of general's blank fanning strip after heat treatment, and the gib head plate of all the other positions and reel, positioning disk then are respectively machined to setting value;
2) the sloping platform face that fanning strip and pyramid axle are in contact with one another is ground to the cooperation shape;
3) the reel parts after the above-mentioned processing are assembled, and on lathe, adopted dial gauge to detect the circular runout situation that respectively leaves surplus amount position,, then research the center hole at reel mandrel two ends if deviation occurs;
4) the reel integral body on heavy machine tool after the assembling is machined to setting value;
5) reel after the processing is detected check.
The present invention compared with prior art, the ovality and the circular runout of its hollow shaft, pyramid axle, the reel mandrel be made up of pyramid axle and fanning strip reduce to 0.05 millimeter by 0.6 millimeter, the circular runout of reel axle head reduces to 0.03 millimeter by 1.2 millimeters.This favourable stable coiling machine rolling tensile force improves coiling speed and improves roll coil of strip product quality and lumber recovery.
