Description

Technical Field

[0001] The present invention relates to the technical field of strip material processing and transportation, and in particular to an automatic strip material chamfering system and a working method. Background Art

[0002] Strips (mainly reinforced flat steel and surface materials, which are collectively called strips because of their integrated nesting and similar processing technology) are widely used in hull structures. They have the characteristics of complex processing technology, many shapes and types, different lengths, high material volume, and large amount of free edge grinding. At present, the free edge processing of strips is generally achieved by chamfering the long edge with a chamfering machine and chamfering the end. During the chamfering operation, the chamfering machine needs to be manually operated to pre-position, clamp, and release the pressure wheel to complete the measurement of different sections of the strip. The operation efficiency is low, the labor intensity is high, and it also brings great safety hazards. Summary of the invention

Both the plate width detection device and the special-shaped end length detection device are connected to a control system, and the control system controls the chamfering machine to move in advance according to the width and thickness of the material to be processed based on the obtained parameters of thickness, width, length and special-shaped length, so as to realize automatic chamfering operation.

[0006] Furthermore, the plate width detection device includes a lifting device and two pairs of photoelectric sensors, the lifting device includes four columns, the two pairs of photoelectric sensors are respectively arranged on the corresponding columns, the lifting device includes the columns and guide rail sliders, the columns are installed above the guide rail sliders, the guide rails are arranged on the conveying roller, and a cylinder is arranged at the bottom of the guide rail slider, and based on the action of the cylinder, the guide rail slider can move vertically along the guide rail.

[0007] Furthermore, the plate length detection and special-shaped end length detection device includes a bracket, an in-place sensing grating, a length measuring roller, and a baffle plate. The in-place sensing grating, the length measuring roller, and the baffle plate are all installed on the bracket. The bracket is fixedly arranged above the conveying roller between the grinding machine and the chamfering machine. The in-place sensing grating is used to detect the strips passing through the grinding machine. The length measuring roller and the baffle plate are vertically movable. The baffle plate falls based on the signal of the in-place sensing grating, and rises after confirming that the strip is stable. The length measuring roller rolls on the strip. The length measuring roller is connected to a length measuring roller encoder to measure the length of the strip.

[0008] Furthermore, a blocking cylinder is provided at the input end of the blocking plate, the blocking cylinder is connected to the control system, the length measuring roller encoder is connected to the pressing roller, the pressing roller is connected to the roller pressing cylinder, and the roller pressing cylinder is connected to the control system.

[0009] Furthermore, a subsequent process of the chamfering machine is provided with a special-shaped end processing device.

[0010] The present invention also discloses a method for using the above-mentioned strip material automatic chamfering system, comprising the following steps:

[0011] After the strip passes through the board width detection device, the control system drives the board width detection device to rise and fall based on the different strip thicknesses, thereby completing the thickness and width detection of different sections of conventional strips or strips with special-shaped ends;

[0012] The strips enter the grinding mill for processing;

[0013] When the in-position sensing grating of the board length detection and special-shaped end length detection device detects that the head end of the strip has entered the detection device area, the control system controls the blocking plate to fall, and controls the length measuring roller to fall to the area where it can contact the head of the strip. After confirming the contact, the control system controls the blocking plate to rise. As the strip moves forward, the length measuring roller completes the length detection of different sections of the conventional strip or the strip with special-shaped ends.

[0014] The control system controls the chamfering machine to perform chamfering based on the acquired thickness, width, length or length data of different segments. During this process, if there is an irregular end, the portion with a preset length is avoided.

[0015] Compared with the prior art, the present invention has the following advantages: the present invention can realize automatic detection of data such as strip width, thickness, length, and length of end profiles (A-head, S-head, water flow hole, etc.), thereby enabling the strips entering the chamfering machine to be processed intelligently and automatically; the chamfering machine can be pre-positioned in advance; and the chamfering machine can be fully automatically operated.

DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0027] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0028] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0029] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0030] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0031] like Figures 1 to 6 As shown, an embodiment of the present invention discloses an automatic chamfering system for strip materials, comprising a plate width detection device 1, a grinding machine 2, a plate length detection, a special-shaped end length detection device 3 and a chamfering machine 4 which are arranged in sequence, the plate width detection device comprises a thickness detection sensor which is arranged above the longitudinal conveying roller and in front of the grinding machine, the special-shaped end length detection device is used to measure the material length and the special-shaped length of the end, the plate width detection device and the special-shaped end length detection device are both connected to a control system, and the control system controls the chamfering machine to pre-position in advance according to the width and thickness of the material to be processed based on the obtained parameters of thickness, width, length and special-shaped length, so as to realize automatic chamfering operation.

[0032] In this embodiment, the grinding machine can be a numerical control grinding machine of 2024208596233. The chamfering machine can be a chamfering machine of the prior art.

[0033] Furthermore, the plate width detection device includes a lifting device and two pairs of photoelectric sensors 5, the lifting device includes four columns, the two pairs of photoelectric sensors are respectively arranged on the corresponding columns, the lifting device includes the columns and guide rail sliders 8, the columns are installed above the guide rail sliders, the guide rails are arranged on the conveying roller, and a cylinder 7 is arranged at the bottom of the guide rail slider. Based on the action of the cylinder, the guide rail slider can move vertically along the guide rail 6.

[0034] Furthermore, the plate length detection and special-shaped end length detection device includes a bracket 14, an in-place sensing grating 9, a length measuring roller, and a blocking plate. The in-place sensing grating, the length measuring roller, and the blocking plate are all installed on the bracket. The bracket is fixedly arranged above the conveying roller between the grinding machine and the chamfering machine. The in-place sensing grating is used to detect the strip passing through the grinding machine. The length measuring roller and the blocking plate are vertically movable. The blocking plate falls based on the signal of the in-place sensing grating, and rises after confirming that the strip is stable. The length measuring roller rolls on the strip, and the length measuring roller is connected to a length measuring roller encoder to measure the length of the strip. The length data is calculated according to the roller diameter and the number of revolutions.

[0035] The end profile length is calculated by the time difference between the inconsistent width data measured by two photoelectric sensors and the number of roller revolutions.

[0036] Furthermore, a blocking cylinder 11 is provided at the input end of the blocking plate, and the blocking cylinder is connected to the control system. The length measuring roller encoder 12 is connected to the pressing roller 13, and the pressing roller is connected to the roller pressing cylinder 10, and the roller pressing cylinder is connected to the control system.

[0037] Furthermore, a subsequent process of the chamfering machine is provided with a special-shaped end processing device.

[0038] The present invention also discloses a method for using the above-mentioned strip material automatic chamfering system, comprising the following steps:

[0039] After the strip passes through the board width detection device, the control system drives the board width detection device to rise and fall based on the different strip thicknesses, thereby completing the thickness and width detection of different sections of conventional strips or strips with special-shaped ends;

[0040] The strips enter the grinding mill for processing;

[0041] When the in-position sensing grating of the board length detection and special-shaped end length detection device detects that the head end of the strip has entered the detection device area, the control system controls the blocking plate to fall, and controls the length measuring roller to fall to the area where it can contact the head of the strip. After confirming the contact, the control system controls the blocking plate to rise. As the strip moves forward, the length measuring roller completes the length detection of different sections of the conventional strip or the strip with special-shaped ends.

[0042] The control system controls the chamfering machine to perform chamfering based on the acquired thickness, width, length or length data of different segments. During this process, if there is an irregular end, the portion with a preset length is avoided.

[0043] During specific use, the special-shaped ends cannot be processed. At this time, the length of the special-shaped ends that do not need to be processed is detected by the plate length detection and the special-shaped end length detection device. The chamfering machine does not process this section. After entering the next process, the special-shaped ends are polished with higher precision.

[0044] During use, the pressure wheel automatically clamps and presses, and releases to perform automatic chamfering operations.

[0045] The application of the fully automatic detection system, through the clever arrangement of various sensors, can achieve accurate measurement of material data; the software control upgrade of the chamfering machine is completed, and the pre-positioning of the pressure wheel and automatic chamfering operations are completed according to the measurement data, reducing waiting time.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
