Abstract
The utility model discloses a roll bite adjusting device for bending rolls of a straightening and withdrawal machine set. The adjusting device comprises at least two sliding support frames arranged below a working roll; a pair of inclined wedges, namely an upper inclined wedge and a lower inclined wedge, are arranged below each sliding support frame; the upper inclined wedge and the lower inclined wedge can slide relative to each other; the upper inclined wedge is fixed at the bottom of the sliding support frame; and the lower inclined wedge is connected with a push-pull rod. By arranging the sliding support frames below the working roll, and arranging the pair of the inclined wedges below each sliding support frame, the utility model can convert horizontal displacement of the push-pull rod into vertical displacement of the sliding support frames, so as to adjust pressure on one section of the working roll independently, and improve the quality of a produced steel plate.
Description
Technical field
The utility model relates to the withdrawal straightening stands in the steel rolling equipment, specifically, is a kind of withdrawal straightening stands bending roll roll gap adjustment device.
Background technology
In the existing steel rolling equipment, the roll gap of equipment bending roll is whole adjusting together, and is parallel constant to guarantee.But, when utilizing equipment processing steel plate, occur occurring on the steel plate hardness ditch defective sometimes, this is generally to be because working roll causes the pressure of steel plate is inconsistent in the axial direction, at this moment need the position that hardness ditch defective occurs is adjusted the pressure of working roll, prior art can't realize this adjustment.
The utility model content
The technical problems to be solved in the utility model provides a kind of adjusting device that can regulate each position roll gap of withdrawal straightening stands bending roll separately.
In order to solve the problems of the technologies described above, the utility model provides a kind of withdrawal straightening stands bending roll roll gap adjustment device, comprise at least two slide holders that are arranged at the working roll below, each slide holder below is provided with a pair of last wedge that can slide mutually and following wedge, wherein go up wedge and be fixed in the bottom of described slide holder, following wedge connects a pull bar.
Further, described pull bar is a leading screw, and described leading screw passes described wedge down, and when described leading screw rotated, described wedge down moved axially along leading screw; Described leading screw connects one and is used to drive the power set that leading screw rotates.
Further, described power set are hydraulic motor.
Further, described pull bar is a hydraulic stem, and described hydraulic stem connects a hydraulic jack.
Further, be provided with bearing between described slide holder top and the working roll.
Further, also be provided with intermediate calender rolls between described bearing and the described working roll.
Further, described slide holder has 4.
Withdrawal straightening stands bending roll roll gap adjustment device of the present utility model, a plurality of slide holders are set below working roll, a pair of wedge by carriage supports frame below, the horizontal displacement of pull bar can be converted to the vertical displacement amount of carriage supports frame, thereby can regulate on the working roll a certain section pressure separately, improve the plate quality that processes.
Description of drawings
Fig. 1 is the structural representation of withdrawal straightening stands bending roll roll gap adjustment device of the present utility model;
Fig. 2 is the vertical view of withdrawal straightening stands bending roll roll gap adjustment device of the present utility model.
Among the figure: 1. hydraulic motor, 2. slide holder, 3. bearing, 4. intermediate calender rolls, 5. working roll, 6. mandrel is 7. gone up wedge, 8. descends wedge, 9. leading screw.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the utility model and being implemented, but illustrated embodiment is not as to qualification of the present utility model.
As shown in Figure 1, see also Fig. 2 simultaneously, withdrawal straightening stands bending roll roll gap adjustment device of the present invention, comprise at least two slide holders 2 that are arranged at working roll 5 belows, each slide holder 2 below is provided with a pair of last wedge that can slide mutually 7 and following wedge 8, wherein go up wedge 7 and be fixed in the bottom of slide holder 2, following wedge 8 connects a pull bar.
In the present embodiment, pull bar is a leading screw 9, and leading screw 9 passes down wedge 8.When leading screw 9 rotated, following wedge 8 can move axially along leading screw 9; Leading screw 9 connects one and is used to drive the power set that leading screw rotates.In the present embodiment, power set are hydraulic motor 1.Power set can also be motor etc.
In other embodiments, pull bar can be a hydraulic stem, and this hydraulic stem connects a hydraulic jack.Under the oil pressure effect, hydraulic stem can promote down wedge 8 and move horizontally.
Being provided with spring bearing 3 above the slide holder 2 and between the working roll 5, also be provided with intermediate calender rolls 4 between bearing 3 and the working roll 5.
In this example, slide holder 2 has 4.
Withdrawal straightening stands bending roll roll gap adjustment device of the present utility model, when hardness ditch defective appears in the steel plate that processes at equipment, find out earlier slide holder that should defective locations, regulate the pull bar of this slide holder below, wedge moves in the horizontal direction to make pull bar promote down, inclined-plane between upper and lower wedge will descend moving horizontally of wedge to be converted to the vertical of wedge and move, and then slide holder and intermediate calender rolls are moved up and down, thereby change the pressure that is applied on the working roll, finally can eliminate the manufacturing deficiency of steel plate.Can accurately control the displacement of pull bar by hydraulic pressure (no matter being hydraulic motor or hydraulic jack), also just can accurately control the pressure that is applied on the working roll, thereby guarantee the flatness of the steel plate that processed.The utility model can be realized the Comprehensive Control to complicated template, reaches the uniformity of drawing of fiber.
The above embodiment is the preferred embodiment that proves absolutely that the utility model is lifted, and protection domain of the present utility model is not limited thereto.Being equal to that those skilled in the art are done on the utility model basis substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
