Description

Technical Field

[0001] The utility model relates to the technical field of steel production, in particular to a straightening machine capable of adjusting straightening passes. Background Art

[0002] The pressure processing process of changing the shape of steel ingots and billets between rotating rollers is called steel rolling. The purpose of steel rolling is the same as other pressure processing. On the one hand, it is to obtain the required shape, such as steel plates, strip steel, wire rods and various steel sections; on the other hand, it is to improve the internal quality of steel. Our common automobile plates, bridge steel, boiler steel, pipeline steel, rebar, electrical silicon steel, galvanized plates, tin plates, including train wheels are processed through steel rolling. The steel rolling method can be divided into hot rolling and cold rolling according to the rolling temperature; it can be divided into longitudinal rolling, transverse rolling and oblique rolling according to the relative motion relationship between the rolled piece and the roller during rolling; it can also be divided into general rolling and special rolling according to the forming characteristics of the rolled product. Cycle rolling, spinning rolling, bending forming, etc. are all special rolling methods.

[0003] Steel plates undergo multiple processes during the production process, such as rolling and cooling. These processes may cause the steel plates to bend, twist or deform to a certain extent. In order to ensure that the flatness and geometric shape of the steel plates meet the requirements, the steel plates need to be straightened using a straightener. In the existing straighteners, the bending part of the steel plates is not fixed during the straightening process, and the straightening passes used by the straighteners to support the steel plates are fixed in position. This cannot ensure that the steel plates can be straightened at any position, which affects the straightening effect. For this reason, we propose a straightening machine with adjustable straightening passes to solve the above technical problems. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] See also Figure 1-6A straightening machine with adjustable straightening passes comprises a supporting leg, a base 1 is fixedly mounted on the top of the supporting leg, an adjustment structure is mounted on the side end of the base 1, and a movable bracket 2 is slidably mounted on the top end, a hydraulic cylinder 3 is mounted on the top end of the movable bracket 2, a pressure block 4 is fixedly connected to the output end of the hydraulic cylinder 3, and a movable adjustment structure is arranged on the top end of the base 1; the movable adjustment structure comprises a plurality of groups of second slide grooves 11 opened on the top surface of the base 1, a plurality of groups of cylinders 12 corresponding to the second slide grooves 11 are fixedly mounted inside the base 1, a movable block 13 is connected to the output end of the cylinder 12, and the movable block 1 The utility model is provided with a plurality of groups of second slide grooves 11 and a plurality of groups of cylinders 12 corresponding to the second slide grooves 11, and the cylinders 12 drive the moving blocks 13 to drive the moving top plates 14 fixedly connected to the moving blocks 13 to move back and forth on the top surface of the base 1, thereby adjusting the gaps between the groups of moving top plates 14, so that the straightening machine can adjust the position of the downward pressure straightening according to the bending parts of the steel plate at different positions, and achieves the effect of being able to straighten any position of the steel plate.

[0028] To achieve the effect of adjusting the straightening pass, refer to Figure 1-3 and Figure 6 During adjustment, the cylinder 12 is controlled and driven by the PLC, so that the cylinder 12 is extended and retracted to drive the moving block 13 fixedly connected to the output end of the cylinder 12 to move forward and backward inside the second slide groove 11, so that the moving top plate 14 fixedly connected to the moving block 13 moves forward and backward. Since the length of the second slide groove 11 is greater than twice the length of the moving top plate 14, when the moving top plate 14 moves, it can be staggered with the position of the first support plate 9 and the second support plate 10. This can provide space for straightening the steel plate and avoid the steel plate touching the moving top plate 14 during the straightening process, causing secondary bending. At the same time, the setting of several groups of moving top plates 14 can enable the straightening machine to achieve the effect of adjusting the straightening passes.

[0029] To achieve the effect of straightening steel plates of different lengths, please refer to Figure 1-5 When it comes to steel plates of shorter lengths, first start the motor 8 to rotate, driving the screw rod 7 to rotate, so that the first slider 6 threadedly connected to the outer wall of the screw rod 7 moves inside the first slide groove 5, thereby driving the first support plate 9 fixedly connected to the first slider 6 to move laterally on the top surface of the base 1, so that the distance between the first support plate 9 and the second support plate 10 is adjusted, which plays a supporting effect when straightening shorter steel plates, so that the straightening machine can be suitable for straightening steel plates of different lengths, thereby improving the compatibility of the straightening machine.

[0030] The movable top plate 14, the first support plate 9 and the second support plate 10 have the same height, which can ensure that the steel plate is in a plane during straightening, and avoid the steel plate from tilting and causing secondary bending during the straightening process.

[0031] Among them, a rubber pad 15 is fixedly installed on the top of the movable top plate 14, and the top surface of the rubber pad 15 is arc-shaped all around, and the top of the opposite surface of the first support plate 9 and the second support plate 10 is also set to be arc-shaped. This structure can prevent the steel plate from appearing concave or bending due to the edges and corners of the supporting components during the straightening process, thereby affecting the straightening effect of the steel plate.

[0032] When in use, first use the adjustment structure to adjust the distance between the first support plate 9 and the second support plate 10 according to the length of the steel plate to adapt to the length of the steel plate. After adjustment, adjust the position of the movable top plate 14 under the steel plate according to the bending part of the steel plate by controlling the extension and retraction of the cylinder 12 through the PLC, so that the straightening machine can straighten the bending parts of the steel plate at different positions. During the straightening process, the mobile bracket 2 is driven by the PLC to move left and right on the guide rail. When it moves to the bending part of the steel plate, the hydraulic cylinder 3 is started to push the pressure block 4 downward to straighten the steel plate.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
