Abstract
The utility model discloses a kind of improved roughing mill AWC hydraulic cylinders, it include the cylinder body with mounting seat, the mounting seat cooperation of cylinder body is inlaid in the side pressure frame body of roughing mill, uniformly the groove that nut is housed in four is arranged in interval on the mounting seat outer peripheral edge, the bolt hole that aperture is 33mm is respectively set in groove, cooperation is installed with four M30 screw rods in bolt hole, and the inner end of four screw rods offsets across the mounting seat with the side pressure frame body lateral wall.The utility model can quickly and easily dismantle AWC hydraulic cylinders, improve overhaul efficiency.
Description
Technical field
The utility model is related to a kind of improved roughing mill AWC hydraulic cylinders.
Background technology
AWC hydraulic cylinders are the important spare parts of roughing mill vertical roll side pressure, after total 4 are arranged in both sides vertical roll frame
Side.AWC hydraulic cylinders push edger roll in the roughing mill operation of rolling, and precision adjustment edger roll roll gap ensures that strip width reaches setting
Width dimensions precision.AWC hydraulic cylinders are mounted on leading screw side pressure frame body.Cylinder body excircle part is bumped on side pressure frame body matches for transition
It closes, cylinder body end face, closing onto side pressure frame body, realizes that the circumference of hydraulic cylinder, axially and radially three-dimensional is fixed by 8 M30 bolts.
AWC hydraulic cylinders needs were replaced according to 2 years service life.Since AWC hydraulic cylinder works environment is poor by flow, oxidation
The erosions such as iron, heat radiation, hydraulic cylinder will produce adhesion with pressure measurement frame body circumference mating surface.It needs now to tear open when online replacement hydraulic cylinder
8 are unloaded conjunction bolt, then dismantles pressure measurement leading screw and the two is disengaged into certain distance with hydraulic cylinder joint bolt, is welded and fixed side pressure frame
Body is pushed between leading screw end face and hydraulic cylinder with 200 tons of hydraulic jack branch until hydraulic cylinder loosens ejection repeatedly.In this way
Leading screw can be damaged, while reduce overhaul efficiency again, if hydraulic cylinder is welded with the close side pressure frame body of frame body adhesion
Fixed point, which can crack, needs Rewelding to fix, and substantially prolongs the time for replacing AWC hydraulic cylinders.Early period only replaces side 2
AWC hydraulic cylinders just need 36 hours or more.
Invention content
The purpose of this utility model is to provide a kind of improved roughing mill AWC hydraulic cylinders, can quickly and easily dismantle
AWC hydraulic cylinders improve overhaul efficiency.
The purpose of this utility model is achieved in that a kind of improved roughing mill AWC hydraulic cylinders, including has installation bottom
The mounting seat cooperation of the cylinder body of seat, cylinder body is inlaid in the side pressure frame body of roughing mill, the installation bottom
Uniformly the groove that nut is housed in four is arranged in interval on seat outer peripheral edge, and the bolt that aperture is 33mm is respectively set in groove
Hole, the interior cooperation of bolt hole are installed with four M30 screw rods, and the inner end of four screw rods passes through the mounting seat and the side
Pressing frame body lateral wall offsets.
Remove AWC hydraulic cylinders when the nut of 4 M30 is put into the slot opened on hydraulic cylinder, nut center respectively with 4 Φ
33 through-hole central alignment is then threaded into 4 M30 screw rods.M30 screw rods are symmetrically tightened by hydraulic pressure with hydraulic spanner or pneumatic impact spanner
Cylinder with pressure measurement frame body is open-top detaches, remove hydraulic cylinder.Generated force effect, will not between AWC hydraulic cylinders and side pressure frame body
It acts on leading screw and destruction is generated to leading screw.It is not required to weld side pressing frame body, 50% or more upkeep operation improved efficiency.
Description of the drawings
The utility model is described in further detail below in conjunction with attached drawing.
Fig. 1 is the main structure diagram of the utility model.
Specific implementation mode
A kind of improved roughing mill AWC hydraulic cylinders, as shown in Figure 1, including the cylinder body 1 with mounting seat 3, liquid
The cooperation of mounting seat 3 of cylinder pressure ontology 1 is inlaid in the side pressure frame body 4 of roughing mill, uniformly distributed on 3 outer peripheral edge of mounting seat
The groove that nut is housed in four is arranged in interval, and the bolt hole that aperture is 33mm is respectively set in groove, matches in bolt hole
Conjunction is installed with four M30 screw rods 2, and the inner end of four screw rods 2 passes through outside the mounting seat 3 and the side pressure frame body 4
Side wall offsets.
Claims (1)
1. a kind of improved roughing mill AWC hydraulic cylinders, include the cylinder body with mounting seat, it is characterized in that：Hydraulic cylinder
The mounting seat cooperation of ontology is inlaid in the side pressure frame body of roughing mill, uniformly interval setting on the mounting seat outer peripheral edge
The groove that nut is housed in four, the bolt hole that aperture is 33mm is respectively set in groove, coordinates in bolt hole and is installed with
The inner end of four M30 screw rods, four screw rods offsets across the mounting seat with the side pressure frame body lateral wall.
