Description

Technical Field

[0001] The present invention relates to the technical field of I-beam processing equipment, and specifically discloses a multi-angle processing equipment for the production of I-beams for the protective door frame. Background Art

[0002] A protective door is a functional door used to provide physical isolation and safety protection. It is usually applied in scenarios such as industry, construction, transportation, and laboratories, aiming to prevent personnel, equipment, or the environment from being threatened externally or at risk internally. Its core functions include bearing impacts, blocking hazards, and maintaining structural integrity. The protective door mainly consists of a frame and a door panel. The selection of the protective door frame needs to be comprehensively considered in terms of strength, weight, corrosion resistance, and cost. Most of its frames are assembled and manufactured using I-beams, C-beams, or U-beams. Among them, the I-beam has a larger sectional moment of inertia. The web of the I-beam can disperse concentrated stress, and the flange of the I-beam enhances lateral stability. Compared with other steel frames, the bending resistance can be increased by about 30% under the same amount of material, making it have multiple advantages of high strength, high structural efficiency, and economy, so that most of the protective door frames use I-beams as the main support structure.

[0003] The invention with the publication number of CN118578131A discloses a steel section automatic cutting machine, including a cutting workbench. A sliding rail is provided on the auxiliary platform, a sliding track is opened on the cutting workbench, the sliding rail is slidably installed in the sliding track, a driving plate is provided on the side of the auxiliary platform, the driving plate is connected with a driving cylinder, a turntable is rotatably installed on the auxiliary platform, the turntable is connected with a rotating motor, a fixed block is fixed on the upper surface of the turntable, and grinding mechanisms are provided on both sides of the auxiliary platform.

[0004] In the disclosed patented technology, the position of the profiled steel is overall positioned by the positioning block and the fixing block, and the profiled steel is cut by the cutting machine in the cutting workbench; the cutting machine in the above-mentioned prior art is vertically arranged, and the profiled steel is cut by adjusting the vertical position of the cutting machine. In actual production and processing, to facilitate the subsequent assembly operation of the I-beam; first of all, the operator needs to obliquely cut the flange corners of some of the I-beams of the protective door frame to facilitate the corner fitting of two adjacent I-beams arranged in a right-angle structure; secondly, it is necessary to drill holes in the web of the I-beam of the protective door frame to facilitate the passing of the beam column and enhance the structural stability of the overall protective door. If the above-mentioned patented technology cutting equipment is used to process the I-beam, since such equipment can only achieve vertical cutting and cannot perform bevel processing and drilling operations, it is necessary for the operator to perform manual cutting and drilling operations after the I-beam is cut; manual cutting and drilling operations rely heavily on manual operation, and the speed is much lower than that of numerical control equipment, making it difficult to meet the requirements of mass production, easily leading to process bottlenecks and affecting the overall production efficiency; moreover, manual operation is easily affected by the technical level, fatigue degree of the workers and the stability of the equipment, and the cut and drilled holes may be inclined, burr or dimensionally deviated, resulting in difficulties in subsequent welding or assembly, and additional rework and correction are required, increasing the time and material costs. To sum up, the processing efficiency and accuracy of the existing cutting equipment cannot meet the requirements of modern large-scale production, and it has become a bottleneck link in the upgrading of the I-beam skeleton manufacturing process.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The conveying table in the present invention can linearly convey the I-beam of the protective door frame in the X-axis direction. Through the transmission action of the conveying rollers, the I-beam is arranged on the rotating table. The processing operator can rotate the rotating table to adjust the inclination angle of the I-beam. Through the cooperation of the chuck and the bearing frame, while clamping the I-beam, the height of the I-beam in the Z-axis direction is increased, so as to facilitate the cutting operation at the flange corners of the I-beam and the overall cutting operation, thereby processing an I-beam that is convenient for corner fitting and meets the production size. On the one hand, the present invention can vertically cut the I-beam to achieve flexible production size processing operations. On the other hand, it can perform bevel processing without manual cutting operations by the operator, improving the production and processing speed of the I-beam, not only improving the production efficiency, but also effectively improving the processing accuracy, without additional rework and correction, further saving the overall production cost of the I-beam; 2. The present invention is provided with symmetrically arranged drilling assemblies on the outer sides of the front end and the rear end of the rotating table. During the conveying of the I-beam on the rotating table, under the clamping action of the chuck, by starting the fifth servo motor, the drill bit rotates at a high speed, and under the driving action of the second servo cylinder, the arrangement position of the first slide seat along the Y-axis direction is adjusted, so that the head of the drill bit approaches the web of the I-beam, thereby opening a plurality of mounting holes on the web of the I-beam. This enables the present invention to perform cutting operations and drilling operations simultaneously. In the field of machining, synchronously performing cutting and drilling operations has significant technological advantages. It can complete the blanking and hole processing of the I-beam at one time, saving the equipment switching, tooling adjustment, and repeated positioning time of traditional step-by-step operations, greatly improving production efficiency. At the same time, it also avoids the hole position deviation caused by clamping errors during step-by-step processing, reducing the man-hour cost of subsequent deburring and calibration processes; 3. By providing conveying rollers on the rotating table, the present invention can be used to match the conveyor belt in the conveying table to form a linkage conveying effect. The conveyor belt is responsible for feeding and stable horizontal conveying, and the conveying rollers can guide the I-beam from the conveyor belt to the rotating table, saving the time of manual auxiliary positioning. This design structure improves the synchronism of the overall equipment, and the matching design structure of the conveying rollers and the rotating table can effectively optimize the production line layout space of the overall equipment, not only reducing the occupied space, but also streamlining the maintenance cost. The present invention takes into account efficiency, durability, and adaptability, meeting the requirements of modern large-scale production layout, and thus has a very wide application prospect.

[0031] The working principle of the present invention is as follows: The I-beam of the protective door frame is placed on the conveyor belt 3 of the conveyor table 2 from the entrance end of the workbench 1. By starting the first servo motor 16, the driving roller 15 drives the conveyor belt 3 to rotate inside the conveyor table 2, so as to linearly convey the I-beam along the X-axis direction to the middle of the workbench 1. If the I-beam of the protective door frame is made of high-strength steel such as Q235B or Q335B, on-site operators can appropriately adjust the arrangement position of the adjusting block 21 to increase the distance between the driving roller 15 and the supporting roller 14, thereby increasing the tension of the conveyor belt 3 and improving the stability of the I-beam during transportation.

[0032] Under the conveying action of the conveyor belt 3, the front end of the I-beam of the protective door frame moves onto the rotating table 4. By starting the third servo motor corresponding to the conveying roller 5 on the side close to the conveyor table 2, the I-beam is linearly conveyed along the X-axis direction on the rotating table 4 until the I-beam is completely arranged on the rotating table 4. By starting the first servo cylinder 42, the clamping plates 8 on both sides of the I-beam clamp it. By starting the fourth servo motor 36, the column 6 rotates, so as to adjust the arrangement height of the bearing frame 7 along the Z-axis direction and lift the arrangement height of the I-beam on the rotating table 4. By starting the second servo motor 26, the rotating table 4 rotates, so as to adjust the inclination angle of the I-beam. By the sixth servo motor 54 and the seventh servo motor 68, the arrangement position of the cutting tool 13 is adjusted, and at the same time, the eighth servo motor 72 is started to make the cutting tool 13 rotate at a high speed, so as to perform cutting operations on the flange corners of the I-beam, thereby processing an I-beam that is convenient for corner fitting.

[0033] Subsequently, under the combined action of the fourth servo motor 36 and the first servo cylinder 42, the I-beam that has completed the cutting operation is placed on the conveying roller 5. By starting the second servo motor 26, the rotating table 4 is reset. By starting the third servo motor 34, the I-beam is linearly conveyed along the X-axis direction from the rotating table 4 to the outflow end of the equipment and is guided outside the device.

[0034] During the conveying process of the above-mentioned I-beam on the rotating table 4, under the clamping action of the chuck 8, by starting the fifth servo motor 908, the drill bit 910 rotates at a high speed, and by cooperating with the driving action of the second servo cylinder 903, the arrangement position of the first slide seat 905 along the Y-axis direction is adjusted, so that the head of the drill bit 910 approaches the web of the I-beam, and thus a plurality of mounting holes are opened on the web of the I-beam. In the present invention, by providing two groups of drilling assemblies 9, the drilling efficiency can be greatly improved, and the production and processing time of the I-beam can be shortened.

[0035] If it is necessary to perform overall cutting on the protective door frame I-beam according to production requirements, the I-beam is arranged along the Y-axis direction, and by starting the third servo motor 34, the arrangement position of the I-beam on the rotating table 4 is adjusted. After the chucks 8 on both sides of the I-beam are stably clamped, the cutting knife 13 cuts the I-beam vertically downward along the Z-axis direction, and the cut part of the I-beam falls on the workbench 1. The on-site staff can arrange a conveying line in this area to convey the excess production materials to the temporary storage area, so as to facilitate subsequent recycling and secondary processing operations.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
