Technical field
The utility model belongs to the mechanical equipment of steel rolling technical field, particularly relates to the side pressure lower device of hot rolling line roughing district, broadband split rolling method rough rolling vertical roller mill in a kind of being applicable to.
Background technology
At present, hot rolling line roughing blooming mill in broadband is generally the 700-800 flat roll mill in being usually used in, and the side pressure lower device of vertical miller usually adopts and manually adjusts structure, and its shortcoming is that a. manually is adjusted into the workman and adjusts roll surface, and it is slow therefore to regulate the speed.B. manually adjustment can only be adjusted roll gap under stopped status, and production status no longer changes, and therefore can't realize being with steel to depress.
Summary of the invention
The utility model provides a kind of employing DC motor drives and transmission nut motion for solving the technical problem that exists in the known technology, realizes the rapid adjustment roll gap and side pressure lower device that be applicable to middle hot rolling line roughing district, broadband split rolling method rough rolling vertical roller mill.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the side pressure lower device of rough rolling vertical roller mill, it is characterized in that: comprising: support, direct current generator is installed on the support, direct current generator connects idler gear by shaft coupling, idler gear is the engaged transmission gear respectively, two travelling gears connect the side pressure screw rod by the hook-type feather key respectively, be equipped with the side pressure nut that is with it movingly on the side pressure screw rod, the side pressure nut is packed on the bearing body of milling train mechanism, side pressure screw rod one end is provided with rotary encoder, arc surface of the other end and the slide block in the bearing body are connected, balance hydraulic cylinder places two side pressure screw rod centre positions, and be connected with frame in the milling train mechanism, in side pressure lower device bottom the synchromesh gear that meshes with travelling gear is housed all, is connected with synchronising (connecting) rod between two synchromesh gears.
The utility model can also adopt following technical scheme:
Described two synchromesh gears connect synchronising (connecting) rod by positive coupling.
The pitch numerical value of described side pressure screw rod is 16mm.
Advantage and the good effect that the utlity model has are: because the utility model has adopted DC motor drives and transmission nut motion, transmission nut drives screw rod again and does straight reciprocating motion, thereby drive edger roll and finish the rolling of different openings degree, and can realize the rapid adjustment roll gap along the frame slide rail is reciprocating; Owing to increased the pitch of side pressure screw rod, improved side pressure speed greatly, thereby improved operating efficiency in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, direct current generator; 2, shaft coupling; 3, rotary encoder; 4, idler gear; 5, travelling gear; 6, side pressure screw rod; 7, hook-type feather key; 8, side pressure nut; 9, slide block; 10, balance hydraulic cylinder; 11, synchronising (connecting) rod; 12, positive coupling; 13, synchromesh gear; 14, support.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the side pressure lower device of rough rolling vertical roller mill, comprise: support 14, direct current generator 1 is installed on support, direct current generator connects idler gear 4 by shaft coupling 2, and idler gear engaged transmission gear 5, two travelling gears respectively connects side pressure screw rod 6 by hook-type feather key 7 respectively, be equipped with the side pressure nut 8 that is with it movingly on the side pressure screw rod, the side pressure nut is packed on the bearing body of milling train mechanism; Side pressure screw rod one end is provided with rotary encoder 3, and the main effect of this rotary encoder is a Stroke Control; The arc surface and the slide block in the bearing body 9 of side pressure screw rod the other end are connected, and in two side pressure screw rod centre positions balance hydraulic cylinder 10 are installed, and are connected with frame in the milling train mechanism; Balance hydraulic cylinder can be used to eliminate crack between the kinematic pair.Between synchromesh gear 13, two synchromesh gears with travelling gear engagement all are equipped with in side pressure lower device bottom, be connected with synchronising (connecting) rod 11, so just can realize being synchronized with the movement under the side pressure at milling train mechanism two ends by positive coupling 12.The pitch numerical value of described side pressure screw rod is 16mm, owing to increased the pitch of side pressure screw rod, can make that speed doubles under the side pressure.
Operation principle of the present utility model is: the direct current generator 1 of side pressure lower device is passed to idler gear 4 by shaft coupling 2 with motion, and idler gear is passed to side pressure screw rod 6 by travelling gear 5 and hook-type feather key 7 and rotated.Because the side pressure nut that is mated 8 is fixing with milling train mechanism 7, then the side pressure screw rod is done straight reciprocating motion simultaneously again rotatablely moving, and drives bearing body and slide block 9 motions, finishes the rolling of different openings degree thereby drive edger roll along the frame slide rail is reciprocating.
