Technical Field

[0001] The present invention belongs to the technical field of numerical control cutting, and particularly relates to a correction system for loading a steel plate onto a numerical control cutting jig, and also relates to a correction method for loading a steel plate onto a numerical control cutting jig. Background Art

[0002] During the construction of numerically controlled cutting of steel plates, whether it is straightening steel plates or numerically controlled cutting, it is required that the longitudinal direction of the steel plate is completely parallel to the numerically controlled cutting track, which requires the operator to proofread during the transportation of the steel plate. The usual method is to use a steel ruler to measure the distance between the edge of the steel plate and the numerical control track, and use a crowbar to pry the steel plate at the end of the steel plate until the two measured distances are exactly the same, which is both time-consuming and laborious.

[0003] Based on this, a correction system and a correction method for loading a steel plate onto a numerical control cutting jig are provided, which not only help the steel plate to be quickly loaded onto the numerical control cutting jig and accurately aligned and corrected, but also can reduce the physical consumption of the operator and improve work efficiency.

Detailed implementation manners

[0044] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0045] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0046] The present invention will be further described below in conjunction with specific embodiments, but it is not intended to limit the present invention.

[0047] Embodiment 1

[0048] Please refer to Figures 1 - 3 , this embodiment provides a correction system for loading a numerically controlled cutting jig for steel plates, which includes: a plurality of positioning mechanisms 11 arranged above a pair of tracks 1 and a lifting and correcting mechanism 2 located between the tracks 1; the straight lines where the plurality of positioning mechanisms 11 located above the same track 1 are parallel to their corresponding tracks 1; the lifting and correcting mechanism 2 includes a first lifting and correcting mechanism 21 and a second lifting and correcting mechanism 22.

[0049] There are a plurality of the first lifting and correcting mechanisms 21, which are evenly distributed between the two tracks 1 in the longitudinal and transverse directions, and their respective motors are synchronously adjusted by a first servo; steel balls 211 that can roll freely are provided at the top of the first lifting and correcting mechanism 21; there are a plurality of the second lifting and correcting mechanisms 22, which are evenly distributed between the two tracks 1 in the longitudinal and transverse directions, and their respective motors are synchronously adjusted by a second servo; rollers 221 are provided at the top of the second lifting and correcting mechanism 22; the rollers 221 roll in a direction perpendicular to the track 1, and drive the steel plate above it to move through friction, so that the side of the steel plate abuts against the positioning mechanism 11.

[0050] In the above correction system for loading a numerically controlled cutting jig for steel plates, two different lifting and correcting mechanisms 2 are provided: among them, the first lifting and correcting mechanism 21 with steel balls 211 at the top facilitates the movement of the steel plate; the second lifting and correcting mechanism 22 with rollers 221 at the top controls the steel plate to translate in a direction perpendicular to the track 1 on the steel balls 211 under the action of the roller motor 223. The first lifting and correcting mechanism 21 and the second lifting and correcting mechanism 22 are respectively provided with servos, which can ensure that multiple similar lifting devices act simultaneously to ensure the levelness of the steel plate. Under the combined action of the two, the steel plate abuts against the preset positioning mechanism 11, thereby realizing the precise alignment of the steel plate above the track 1.

[0051] Specifically, a plurality of the first lifting and correcting mechanisms 21 are evenly distributed between the two tracks 1, and the top of the first lifting and correcting mechanism 21 is provided with steel balls 211 that can roll freely, and the rolling performance of the steel balls 211 can be improved by adding lubricating oil, thereby reducing the resistance during the movement of the steel plate, so that the steel plate can move easily above the lifting and correcting mechanism. The second lifting and correcting mechanism 22 is a device for controlling the movement of the steel plate, and the rotation direction of the rollers 221 at the top thereof is perpendicular to the longitudinal direction of the steel plate (i.e., the direction of the track 1), and the rotation of the rollers 221 with friction drives the steel plate to move in the horizontal direction, so that it moves towards the direction close to the track.

[0052] Furthermore, in this embodiment, the first lifting and correcting mechanism 21 and the second lifting and correcting mechanism 22 are arranged in a staggered manner in a row parallel to the track 1. Such an arrangement helps the steel balls and rollers to cooperate better and improves the efficiency of steel plate alignment. The specific number of the first lifting and correcting mechanism 21 and the second lifting and correcting mechanism 22 is set according to the size of the steel plate, and the bearing capacity of the first lifting and correcting mechanism 21 and the rolling performance of the second lifting and correcting mechanism 22 also need to be referred to.

[0053] The correction system provided by the present invention is mainly aimed at the whole steel plate or large-piece surplus steel plates. For steel plates with a length ≥ 3 meters and a width ≥ 1 meter, the longitudinal and transverse arrangement examples of the first lifting and correcting mechanism 21 and the second lifting and correcting mechanism 22 are ≤ 500 mm.

[0054] The present invention evenly arranges the first lifting and correcting mechanism 21 and the second lifting and correcting mechanism 22 in the gaps of the numerical control cutting jig partition plates to ensure uniform load bearing and reasonable force during the rotation process. At the same time, the first lifting and correcting mechanism 21 and the second lifting and correcting mechanism 22 are respectively connected through a servo, and are provided with their respective corresponding synchronous motors to ensure the consistency of the steps of multiple lifting devices during the rising process.

[0055] Please refer to Figures 4 - 6 , the first lifting and correcting mechanism 21 includes a hydraulic lifting device at its bottom. A steel ball base is installed at the movable end of the hydraulic lifting device, and the steel ball 211 can roll flexibly in the base. The first lifting and correcting mechanism 21 further includes a first protection device 212 covering above the steel ball 211, and the first protection device 212 is selected to be opened or closed according to the working state of the first lifting and correcting mechanism 21. In this embodiment, the first protection device 212 includes a pair of covers and a control member below the covers. The pair of covers open downward to both sides in the open state and cover above the steel ball 211 in a hemispherical shape in the closed state.

[0056] In the present invention, by arranging the first protection device 212 outside the steel ball 211 of the first lifting and correcting mechanism 21, controlling the first protection device 212 to be opened during the lifting process to ensure that the steel plate can move on the surface of the steel ball 211; the first protection device 212 is closed during the descending process of the lifting mechanism and covers outside the steel ball 211, which can prevent the steel ball 211 from being cut or splashed by the melted iron slag during the steel plate cutting process and affecting the free rolling effect of the steel ball, effectively avoiding damage to the steel ball surface and increasing resistance, and further affecting the smooth movement of the steel plate.

[0057] Please refer to Figures 7 - 10, the second jacking and correcting mechanism 22 includes a hydraulic jacking device at its bottom. A roller base is installed at the movable end of the hydraulic jacking device. The bearings of the roller motor 223 and the roller 221 are connected by gears. The roller motor 223 drives the roller 221 to rotate through the gears. A plurality of rollers 221 are evenly distributed in the gaps between the longitudinal and transverse diaphragms of the jig. All the roller motors 223 are synchronously adjusted to rotate through the roller motor servo, and then the rollers 221 rotate, thereby driving the steel plate to move. The second jacking and correcting mechanism 22 further includes a second protection device 222 covering above the rollers 221. The second protection device 222 is selectively opened or closed according to the working state of the second jacking and correcting mechanism 22. In this embodiment, the structure of the second protection device 222 can be similar to that of the first protection device 212, or other forms can be adopted, and no excessive limitation is made.

[0058] In the present invention, by arranging a second protection device 222 outside the rollers 221 of the second jacking and correcting mechanism 22, the second protection device 222 is controlled to be opened during the jacking process to ensure that the steel plate can roll on the surfaces of the rollers 221 and the steel balls 211; the second protection device 222 is closed during the descending process of the jacking mechanism and covers the outside of the rollers 221, which can prevent the rollers 221 from being cut or splashed by the molten iron slag during the steel plate cutting process, avoiding damage to the surfaces of the rollers 221, the roller motors 223 and the gears during the cutting process, and ensuring the smooth and normal operation of the correction system.

[0059] Preferably, the covers of the first protection device 212 and the second protection device 222 are made of Q235 steel plates with a thickness of 2 - 3 mm.

[0060] Furthermore, in order to improve the effect of the rollers 221 rotating to drive the steel plate to move, in this embodiment, the rollers 221 are made of wear-resistant elastic plastic. The wear-resistant elastic plastic helps to increase the friction between the steel plate and the rollers, effectively avoiding the phenomenon of relative movement and slipping between the steel plate and the rollers during the rotation of the rollers.

[0061] Please refer to Figure 11, taking the positioning mechanism 11 on the left side as an example, the positioning mechanism 11 includes a jacking device 111 and a stopper 112. The stopper 112 is installed at the movable end of the jacking device 111. The straight line where multiple stoppers 112 on the same side are located is parallel to its corresponding track 1. Further, a third servo is provided between multiple positioning mechanisms 11 on the same side for controlling the synchronous movement of multiple positioning mechanisms 11. During the specific operation process, according to the width of the steel plate, the extending length of the movable end of the jacking device 111 of each positioning mechanism 11 is adjusted to make them consistent, and each stopper 112 on the same side is located on a straight line parallel to the track 1. During the subsequent calibration process, the movement of the steel plate is realized by using the roller 221 and the steel ball 211, so that its edge approaches the preset stopper, that is, the alignment operation of the steel plate and the track is realized.

[0070] Further, the calibration method further includes: in step four, during the process of starting the second jacking calibration mechanism 22 to move downward, the second protection device 222 is closed and covered above the roller 221; during the process of starting the first jacking calibration mechanism 21 to move downward, the first protection device 212 is closed and covered above the steel ball 211.

[0071] During the above operation process, the first protection device 212 and the second protection device 222 are opened during the ascending process of the jacking calibration mechanism 2, so that the steel ball 211 and the roller 221 are exposed, facilitating subsequent steel plate position adjustment operations; the first protection device 212 and the second protection device 222 are closed during the descending process of the jacking calibration mechanism 2, so that the two are respectively covered above the steel ball 211 and the roller 221 to protect the steel ball 211 and the roller 221, preventing damage to the surfaces of the steel ball 211 and the roller 221 during the subsequent numerical control cutting process, extending the service life of the equipment, and ensuring the normal operation of the system.

[0072] The above are only preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be realized that all equivalent replacements and obvious changes made by using the content of the specification of the present invention should be included in the protection scope of the present invention.
