The specific embodiment
As shown in Figure 1, straightener pitch-adjusting device, comprising: straightening machine body 2, be arranged on some roll bodies 1 and lead screw transmission unit 3 on straightening machine body 2.Fig. 1 is the installation diagram of this straightener entirety, and in this embodiment, roll body 1 adds up to seven.
Described roll body 1 two ends are provided with roller seat 6, roller seat 6 is located on described straightening machine body 2, some roll bodies that be arranged in parallel 1 are lined up upper and lower two row compositions upper and lower roll unit, and roll body 1 in upper and lower roll unit is spaced, shaped steel from the middle of upper and lower roll unit by aligning.
3 points of described lead screw transmission unit are located at described straightening machine body 2 both sides, comprising:
One motor 21 is fixed on straightening machine body 2;
Two cocainine thick sticks 24, it is connected with motor 21, and motor 21 rotates and drives leading screw 24 to rotate, and leading screw 24 is perpendicular to roll body 1;
Described two cocainine thick stick 24 overcoats connect the roller seat 6 of roll body 1 in succession, each roller seat 6 is provided with in the travel range that the screwed hole running through makes roller seat 6 limit at leading screw 24 and moves, and the pitch difference of the leading screw 24 in each roller seat 6 travel range, leading screw 24 rotate drive each roller seat 6 on straightening machine body 2 along the axial left and right movement of leading screw 24, form the mutual horizontal range of roll body 1 (being pitch) and change, change of distance amount is directly proportional to the pitch of leading screw 24 in roller seat 6 travel range.
Two cocainine thick sticks 24 of described lead screw transmission unit 3, wherein, cocainine thick stick 24 overcoats connect the roller seat 6 of two roll bodies 1 in roller unit, the roller seat 6 of a roll body 1 in the outer socket lower roll of a cocainine thick stick 24 unit below, and guarantee that leading screw 24 drives in roller seat 6 moving process, below the roller seat 6 of roll body 1 on a cocainine thick stick 24 be positioned at all the time in the middle of the roller seat 6 of two roll bodies 1 on a cocainine thick stick 24 above.Leading screw 24 is provided with protective cover 25 with roller seat 6 junctions and fixes also spacing.
In the present embodiment, lead screw transmission unit 3 is arranged on straightener both sides, by two sub-sections left and right.The intermediate calender rolls of tri-roll bodies 1 of the 2nd roll body 1(in lower roller unit) fixing, the roller seat 6 of this roll body 1 is fixed together with the upper and lower crossbeam of straightening machine body 2.As center, other six roll bodies 1 are divided into two parts, go up 1 two of roll bodies, 1 one of lower roll bodies, connect respectively left and right two cover leading screw gear units 3.
Upper roller unit does not have press down system, so that the roll body 1 of upper roller unit is installed the roller seat 6 at place is highly little, the leading screw 24 connecting at the roller seat 6 of the roll body 1 of upper roller unit only has one can meet strength demand.On the contrary because lower roller unit connects complete machine height adjusting unit 5, so that the roll body 1 of lower roller unit is installed the roller seat 6 at place is highly higher.For envoy is apart from adjusting steadily, respectively there is a rhizoid thick stick 24 in the top and bottom of the roller seat 6 of lower roller unit.Due to two roll bodies 1 being housed on the leading screw 24 at upper roller unit, that is to say that this leading screw 24 adjusts the position of two roll bodies 1 simultaneously.
The pitch that just must make to be connected to leading screw 24 within the scope of roller seat 6 internal thread pitch on leading screw 24 and 6 movement travels of this roller seat for obtaining equal pitch adjustment is different from the pitch of other group roller seats 6 and leading screw 24, descends roller unit to be connected to the pitch of leading screw 24 and roller seat 6 simultaneously also not identical.Leading screw 24 pitch ratios of this straightener are, the roller seat 6 of the first roll body 1 of top roll: the roller seat 6 of the second roll body 1 of top roll: the roller seat 6 of the roll body 1 of lower roll, forms the ratio of 3:2:1, thereby guarantee equal pitch adjustment.The roller seat 6 of the roll body 1 on a cocainine thick stick 24 is positioned in the middle of the roller seat 6 of two roll bodies 1 on a cocainine thick stick 24 above all the time below.(as shown in Figures 2 and 3)
Also comprise outlet roller 4, discharging one end after being arranged at straightening machine body 2 beam straightenings and completing.
Also comprise complete machine height adjusting unit 5, it is located at straightening machine body 2 lower ends, and the height of straightening machine body 2 is carried out to upper and lower adjusting.This complete machine height adjusting unit 5 can adopt hydraulic pressure or air pressure erecting equipment, also can adopt other forms of straightener integral position lifting equipment simultaneously.Object is the size range of the shaped steel of expanding to a greater extent processing, increases compatible.
Also comprise turbine worm reducer 22, it is located between lead screw transmission unit 3 motors 21 and leading screw 24, connects and reduces rotating speed.The rotating speed that motor 21 directly transmits may exist speed fast, and has the situation of the fluctuation of speed, is unfavorable for that stable transmission rotating speed is to leading screw 24.So the turbine worm reducer 22 of an energy stable delivery rotating speed is set.Leading screw 24 is also provided with bearing 23 with worm-gear speed reducer 22 junctions, for improving the stability of rotation.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present invention.All equalization variation and improvement etc. of doing according to the utility model scope, within all should still belonging to this patent covering scope.
