Description

Technical Field

[0001] The present invention relates to the technical field of steel production, and more particularly, to a steel transmission system. Background Art

[0002] Steel structure engineering is one of the main building structure types. It is one of the common structural forms in modern construction projects. Steel structure engineering is a structure mainly made of steel. Steel structures include steel plates.

[0003] The current steel transmission method is that each independent device operates separately. The pretreatment device is only responsible for the pretreatment function, and after pretreatment, the steel plate is marked and segmented.

[0004] However, the current steel transmission method has certain deficiencies. First, the current steel transmission method does not have a detection and classification function. The thickness of the produced steel plates is inconsistent, and medium and thick steel plates are processed in the next step without leveling, which will result in poor flatness of the steel plates and affect the accuracy of subsequent marking and cutting of the steel plates. Second, the current steel transmission method does not have a defect detection function, resulting in many steel plates with large defects participating in the process from the beginning of the processing, resulting in uneven quality of the final products. Finally, the current steel transmission method does not integrate each device to form a complete transmission system, which is not convenient for unified management. Summary of the Invention

[0005] In view of the above technical problem that the existing technology does not have a defect detection function, a steel transmission system is provided. The present invention mainly sets a defect detection unit to detect whether the steel plate defects meet the standards, and the steel plates that do not meet the standards are repaired and then participate in the process, so as to improve the quality of the finished steel plates.

[0006] The technical means adopted by the present invention are as follows:

[0007] A steel transmission system, comprising:

[0008] A feeding roller table, which transports the steel plate from the feeding port to the pretreatment unit;

[0009] A pretreatment unit, which pretreats the steel plate;

[0010] A defect detection unit, which detects the defects of the pretreated steel plate and marks the defects of the steel plate. The defect detection unit judges the defects of the steel plate. When the defects of the steel plate meet the standards, it is transmitted to the detection unit. When the defects of the steel plate do not meet the standards, the steel plate is transmitted to the repair unit;

[0011] The detection and classification unit conducts thickness detection on the steel plates that have passed the defect detection. When the steel plate is a thin steel plate, it transports the thin steel plate to the scribing unit; when the steel plate is a medium-thick steel plate, it transports the medium-thick steel plate to the leveling unit.

[0012] The leveling unit levels the medium-thick steel plate and transports the leveled medium-thick steel plate to the scribing unit.

[0013] The scribing unit scribes the steel plate.

[0014] The cutting unit cuts the scribed steel plate along the scribed line.

[0015] Furthermore, the pretreatment of the steel plate includes removing the scale, impurities and painting the steel plate.

[0016] Furthermore, the repair unit repairs the steel plate according to the defects on the steel plate and transports the repaired steel plate to the feeding roller table.

[0017] Furthermore, the cutting unit includes several cutting machines. The cutting unit detects the working states of the several cutting machines and transports the steel plate to the idle cutting machine for cutting through a transverse moving trolley.

[0018] Furthermore, the number of the scribing units is greater than one. The detection and classification unit transports the steel plate to the corresponding scribing unit according to the use of the steel plate.

[0019] Furthermore, the cutting machine is a plasma cutting machine.

[0020] Furthermore, the leveling unit includes a leveling transport roller table and a leveling machine.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] The present invention mainly detects the defects of the steel plate through the setting of the defect detection unit, and the steel plates that do not meet the standards are repaired and then participate in the process, so as to improve the quality of the finished steel plate.

[0023] The present invention classifies the steel plates into thin steel plates and medium-thick steel plates through the setting of the detection and classification unit, and levels the medium-thick steel plates to achieve the flatness of the steel plates before scribing and cutting the bevel, and at the same time can ensure the processing accuracy of the steel plates in the subsequent process.

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. The description of at least one exemplary embodiment below is actually only illustrative and in no way restrictive of the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0033] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they specify the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0034] Unless otherwise specifically stated, the relative arrangements of the components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be clear that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the authorized specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not require further discussion in subsequent drawings.

[0035] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be construed as limiting the protection scope of the present invention. The orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the attached drawing is inverted, a device described as "above or over other devices or structures" will then be positioned as "below or under other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.
