Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel plate straightening, in particular to a hot-rolled steel plate straightening device. Background Art
[0002] Hot-rolled steel plate is a steel plate manufactured by hot rolling process. After the production of this steel plate is completed, in order to ensure that some slightly bent steel plates can be straightened, a special straightening device will be used to straighten them, so that the straightened steel plates have a higher level. When straightening such hot-rolled steel plates with a relatively light degree of bending, most of them will directly use hydraulic equipment for direct correction, and the bent steel plates will be directly straightened by a press from top to bottom.
[0003] However, in the process of direct straightening using hydraulic equipment, since the steel plate is placed flat on the straightening table, after straightening is completed, the bottom of the entire steel plate is completely in contact with the table, which makes it difficult to pick up the straightened steel plate manually. It is necessary to push a corner or one side of the steel plate to the edge of the table to make a hollow underneath before it can be picked up. The picking up process is relatively inconvenient and can easily cause damage to fingers or nails. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Example 1
[0026] like Figure 1-5 As shown, a hot-rolled steel plate straightening device comprises a straightening platform 1, a gantry 2 installed above the top of the straightening platform 1, and a support plate 5 installed below the bottom of the straightening platform 1.
[0027] A hydraulic cylinder 3 is installed on the top of the gantry 2, and the output shaft of the hydraulic cylinder 3 extends into the gantry 2. A straightening pressure strip 4 is fixedly installed on the output shaft of the hydraulic cylinder 3. The output shaft of the hydraulic cylinder 3 drives the straightening pressure strip 4 to move up and down.
[0028] Furthermore, two reinforcing rods are slidably installed on the top of the gantry 2, and the bottom ends of the two reinforcing rods are fixedly connected to the straightening strip 4. The reinforcing rods facilitate the guidance of the output shaft of the hydraulic cylinder 3 and improve the strength of the straightening strip 4.
[0029] The straightening platform 1 is provided with a plurality of movable openings 6 evenly distributed along the length direction of the straightening platform 1, and a lifting plate 7 that can move up and down is arranged in each of the plurality of movable openings 6, and a lifting device is arranged at the bottom of the lifting plate 7, and the lifting device controls the lifting and lowering of the lifting plate 7. Specifically, the lifting device is a telescopic cylinder 13, and a lifting column 9 is fixedly installed at the bottom of each of the plurality of lifting plates 7, and a pushing head 14 is fixedly installed on the output shaft of each of the plurality of telescopic cylinders 13, and the pushing head 14 is adapted to the lifting column 9.
[0030] In the initial state, the top end surface of the lifting plate 7 is flush with the top end surface of the straightening table 1, and a lifting column 9 is fixedly installed at the bottom of each lifting plate 7, and the pushing head 14 is located below the lifting column 9. By extending the output shaft of the telescopic cylinder 13, the lifting column 9 and the lifting plate 7 can be pushed up, so that the straightened steel plate can be lifted.
[0031] Further, such as Figure 4 As shown, two side blocks 19 are fixedly installed on the top of the plurality of lifting plates 7, and the hot-rolled steel plates can be directly placed between the two side blocks 19, which is convenient for the placement and positioning of the hot-rolled steel plates.
[0032] Example 2
[0033] This embodiment is based on the embodiment 1, and a further solution is that in order to ensure that the top end surface of the lifting plate 7 and the top end surface of the straightening table 1 are on the same horizontal plane, and in order to save the usage of the telescopic cylinder 13 and reduce the equipment cost, Figure 4 As shown, a concave frame 8 is fixedly installed at the bottom of the straightening table 1, and a plurality of lifting columns 9 all penetrate the concave frame 8 and are slidably connected to the concave frame 8. A retaining ring 10 is fixedly sleeved on the plurality of lifting columns 9, and the bottom of the retaining ring 10 contacts the bottom inner wall of the concave frame 8. The retaining ring 10 is limited so that the lifting plate 7 cannot continue to sink in a natural state, thereby ensuring the flatness of its top end surface and the surface of the straightening table 1.
[0034] like Figure 2-3 As shown, a bidirectional lead screw 11 is rotatably arranged on the support plate 5, the threads at both ends of the bidirectional lead screw 11 are symmetrical along the middle of the bidirectional lead screw 11, and the rotation directions of the threads are opposite, and a sliding seat 12 is respectively arranged on the threads at both ends of the bidirectional lead screw 11, and two telescopic cylinders 13 are arranged, and the two telescopic cylinders 13 are arranged on two sliding seats 12. Only two telescopic cylinders 13 are used, and the bidirectional lead screw 11 is driven by a motor, so as to control the telescopic cylinder 13 to move to the lower part of the lifting plate 7 to be lifted.
[0035] There are two support plates 5, which are respectively arranged on both sides of the bottom of the straightening table 1. The same horizontal bar is fixedly installed on the two support plates 5, and the horizontal bar passes through the two sliding seats 12 and is slidably connected to the two sliding seats 12. The horizontal bar passes through the two sliding seats 12 and is slidably connected to the two sliding seats 12, thereby providing a restriction for the sliding seats 12 so that they can only move linearly horizontally.
[0036] A motor is fixedly mounted on one side of one of the support plates 5 , and an output shaft of the motor is fixedly connected to one end of the bidirectional lead screw 11 .
[0037] Example 3
[0038] This embodiment is based on Embodiment 1 and Embodiment 2, and a further solution is to prevent the steel plate from sliding sideways during the process of lifting the steel plate after the steel plate is straightened.
[0039] like Figure 1 , Figure 5As shown, rodless cylinders 15 are fixedly installed on the outer walls of both sides of the gantry 2, connecting blocks 16 are fixedly installed on the sliders of the two rodless cylinders 15, and guide rods 17 are fixedly installed on the sides of the two connecting blocks 16 close to each other. The two guide rods 17 respectively penetrate the two sides of the gantry 2 and are slidably connected to the two sides of the gantry 2, and the ends of the two guide rods 17 close to each other are fixedly installed with push plates 18, and the bottoms of the push plates 18 are in contact with the straightening table 1.
[0040] After straightening is completed, the rodless cylinder 15 is started, and the steel plate can be pushed to the horizontal center position through the two pushing plates 18 approaching each other, and then it can be lifted, thereby ensuring the stability of the center of gravity of the steel plate when lifting. In addition, two side blocks 19 are fixedly installed on the top of each lifting plate 7 to form front and rear barriers for the steel plate to prevent front and rear deviation.
[0041] Working steps:
[0042] When straightening a slightly bent steel plate, first place the steel plate on the straightening table 1 and between the side stops 19, then start the output shaft of the hydraulic cylinder 3 to extend, and the output shaft brings the straightening strip 4 down, and when the straightening strip 4 contacts the steel plate, the straightening work of the steel plate begins;
[0043] After the steel plate is completely straightened, the output shaft of the hydraulic cylinder 3 is retracted to bring the straightening strip 4 back to its original position, and then the two rodless cylinders 15 are started, and the sliders on the two rodless cylinders 15 move toward each other, so that under the push of the guide rod 17, the two straightening plates 18 move toward each other, and finally the steel plate is pushed to the horizontal center position;
[0044] Then, according to the length of the steel plate, the two lifting plates 7 to be used are selected. After the selection is completed, the positions of the two pushing heads 14 are adaptively adjusted to correspond to the lifting plates 7 to be used. During the adjustment, the motor is started, and its output shaft drives the bidirectional screw 11 to rotate, so that the two sliding seats 12 move relative to each other until the two sliding seats 12 move to the specified position and then the motor is turned off. Then, the output shafts of the two telescopic cylinders 13 are started to extend. When the two pushing heads 14 contact the corresponding lifting columns 9, they will bring the corresponding lifting plates 7 up, so that the straightened steel plates can be gradually lifted. After being completely lifted, the steel plates are separated from the straightening table 1, and then the steel plates can be removed manually. After removal, the output shaft of the telescopic cylinder 13 is started to retract, and the lifting plates 7 are brought back to their original positions.
[0045] Compared with the related art, the hot rolled steel plate straightening device provided by the utility model has the following beneficial effects:
[0046] The utility model provides a hot-rolled steel plate straightening device, which can quickly straighten the bent steel plate by means of the arranged hydraulic cylinder 3 and the straightening pressure strip 4, and after the straightening is completed, the steel plate can be lifted up by means of the extension of the output shaft of the telescopic cylinder 13, so that there is a distance between the steel plate and the straightening table 1, thereby making it convenient for people to hold the steel plate and take it away directly, bringing greater convenience to people's use and being easy to operate. Compared with the traditional method which requires pushing the steel plate to the edge of the table before taking it, this method is faster and less likely to hurt fingers.
