Abstract
The utility model provides a ball cold-rolling mill which separates the transmission system form a main mill; a universal drive shaft is arranged between the roller main shaft of the main mill and a gear box; the two rollers are arranged at one end of the rollers main shaft on outer roll-box in cantilever form; the two roll-boxes are respectively arranged on a rotatable bracket and a movable bracket. The utility model is characterized in that each technological parameter of mills is adjusted conveniently; the vibration of the main mill is small, the utilization of mills is high, and the quality of products is good. The utility model has the advantages of high precision, and convenient maintenance.
Description
The utility model relates to a kind of double-roller type ball rolling mill that is suitable for the following steel ball of cold rolling φ 6mm.
Diameter is at the steel ball below six millimeters, and general many with cold rolling production, the present milling train of using always has jaw type milling train and frame milling train.The jaw type milling train, roll adopts two fulcrums to be placed in the jaw that is square, and depresses by the distance change of both sides jaw, and the phase place of roll and axial location are adjusted on same roll main shaft, transmission system and main mill are same body, and gear is only by a universal joint dummy roll.Though this milling train structure is fairly simple, exists following deficiency, adjustment causes when depressing that roll line changes up and down; The phase place adjustment and the axial location adjustment of roll interact; The roll main shaft very easily weares and teares; Main mill serious vibration during running influences the product precision; Under prop up sheet mounting or dismounting and adjust all difficulties; Plant maintenance inconvenience.And the frame milling train has adopted the version that is similar to the double-roller type Mannesmann piercing mill.The entablature opening, the bottom is flute profile, and therefore, roll is depressed and is adjusted the no longer variation of influence of rolled line position, and roll turns round by the direct geared transmission, has kept the constant speed rotation of roll.But the frame milling train is also kept away unavoidable following not enough: because of roll adopts two fulcrums, still difficulty is adjusted in following sheet mounting or dismounting; Roll mandrel is to adjusting still by adjusting the screw back of the body cap of stationary roll, operation inconvenience, as screw back of the body cap directly and main shaft link, main shaft still very easily weares and teares; Transmission system places in the host shell, generally all adopts the common conical gear of many, quick abrasions low to efficient, thereby mechanism's complexity not only, safeguards assembling inconvenience, and the vibration of whole machine body is also bigger during running, influences product quality.This shows, above-mentioned two kinds of existing common drawback of milling train are, the installation of a roll and a sheet and adjustment are all very difficult, the interference each other that has between each parameter that milling train is adjusted, make troubles to practical operation, and milling train when motion vibration is bigger, influence product quality, thereby causes milling train utilization rate and adjustment precision all not high.
In view of the existing deficiency of above-mentioned milling train, a kind of installation is provided the utility model and adjustment is simple, easy to maintenance, the little novel ball rolling mill of vibration when roll turns round.
Cantilevered steel ball cold-rolling mill provided by the utility model for achieving the above object is made up of gear-box and main mill two parts, and is connected two universal drive shafts between gear-box and main mill.According to shown in Figure 1, the roll main shaft (11 of gear-box (2) and main mill (21), 14) connect two universal drive shafts (4) between, main mill comprises hold-down transmission device (6), can move support (8), roll-box (10,15), swinging bracket (19) and two rolls (12,13), roll (12,13) all be arranged on roll main shaft (11 with cantilevered fashion, 14) same end, roll main shaft (11,14) be arranged on roll-box (10,15) on, roll-box (10) is fixed on and can moves on the support (8), and roll-box (15) is fixed on the swinging bracket (19).The radial displacement of two roll shop buildings, promptly depressing of roll adjusted by the threaded rod (7) that hold-down transmission device (6) reaches and can move between support by rocking handle (5); The axial displacement of roll is adjusted by the mechanism for axial adjusting (18) on the swinging bracket (19), and this mechanism for axial adjusting adopts the bolt slide block mechanism, and roll-box (15) is moved vertically with respect to swinging bracket; The loudspeaker bicker of roll is rotated swinging bracket by bolt slide block mechanism (20) and is adjusted around locating shaft (18), the axis normal of locating shaft (18) is in the horizontal axis I-I of roll pass outlet; Be positioned between moved support on I-I line and the roll-box (10) and between swinging bracket and the roll-box rotation pivot (9,16) all is set, after making roll-box adjust needed roll feed angle with this rotation pivot, roll-box is fixed in and can moves on support and the swinging bracket; The phase place adjustment of roll is adjusted by the end tooth arrangement of clutch (3) on the gear-box.Like this by the belt pulley (1) of driven by motor after reduction box slows down, by two universal drive shaft dummy roll main shafts, the pole blank shows that by the arrow among the figure direction sends into roll and be rolled required steel ball, and the steel ball base that rolls into is vowed by the dotted line among the figure and shown the direction foreground feeder of rolling back.
The utility model is by the above-mentioned cantilevered steel ball cold-rolling mill that structure provided, and has the phase place, feed angle, loudspeaker bicker, roll axial location of easy adjustment roll and the characteristics of technological parameter such as drafts radially, and each parameter is independent of each other when adjusting; In addition; because of roll form is arranged on outside the roll-box, adjust the worker and can directly observe measurement at cantilever end, milling train reliability and the accuracy adjusted; prevent a pad wear roll, thereby avoided tearing open repeatedly of axle to transfer the main shaft that more helps protecting milling train.Feed angle that another distinguishing feature of the present utility model is a roll and loudspeaker bicker all are as the criterion with the horizontal axis I-I of roll pass outlet, thereby guarantee to adjust precision.From the integral layout of milling train, because transmission system and main mill are separated, thus the vibration that can alleviate main mill itself when turning round, this is also with the raising of favourable ball base quality.This shows, the utlity model has milling train utilization rate height, the good characteristics of product quality, can be widely used in the following small-sized steel ball field of rolling φ 6mm.
Embodiment of the present utility model:
According to Fig. 2, shown in Figure 3,22 is belt pulley, 23 is gear-box, and 24 are the end tooth arrangement of clutch with the adjustment phase place, and 25 is universal drive shaft, 26 is hold-down transmission device, 27 for can move support, and 28 are a horse, and 29 for being fixed in the roll-box that can move support, 30,31 is roll, 32 for being fixed in the roll-box of swinging bracket, and 33 for being used to adjust the bolt slide block mechanism of roll axial location, and 34 is roll-box, 35 for being used for adjusting the bolt slide block mechanism of loudspeaker bicker, 36 is last sheet, and 37 are a following sheet, 38,39 for being used to adjust one group of bolt of feed angle, 40 is the end seat of main mill, and 41 is the end seat of gear-box.The length of this rolling mill roll is about 30mm, and the adjusting range of feed angle is ± 6 °, and the adjusting range of loudspeaker bicker is ± 5 °, and the axial location adjusting range of roll is at 15mm, and the work adjusting range of the radial position of roll is at 30mm.
