Description

Technical Field

[0001] This application relates to the field of metal stamping technology, and in particular to a channel steel stamping auxiliary system and method of use for the manufacture of air-raid shelter doors. Background Technology

[0002] Civil defense doors are special protective doors mainly used in underground civil defense projects. In the event of emergencies such as terrorist attacks or typhoons, the civil defense doors are closed to isolate the underground civil defense from the outside world, providing people with a safe refuge.

[0003] The main structure of a civil defense door consists of two door panels. Closing the two door panels constitutes the closure of the civil defense door. Each door panel consists of two door panels and a supporting mesh in the middle. The assembly process is briefly described below: The welder first places a single door panel horizontally in the installation area, then places a single narrow steel plate vertically on the single door panel, tilting it towards the door panel, and welds it. Multiple narrow steel plates are placed crosswise and welded to form a support mesh. Then, another door panel is placed above the support mesh, and the two door panels sandwich the support mesh to form the door panel of a single leaf. Finally, the welder installs four channel steel frames, which are adapted to the length of each side of the door panel, onto the four sides of the two door panels and the support mesh, and welds them to form a single leaf.

[0004] Reference Figure 1 A channel steel frame includes a base plate 21 and side plates 22 welded to the two sides of the base plate 21. The base plate 21 is longer than its width and is narrow. The two side plates 22 are arranged parallel to each other and perpendicular to the base plate 21. The length of the base plate 21 is greater than the length of the side plates 22. One end of the base plate 21 is flush with one end of the two side plates 22, and the other end of the base plate 21 protrudes beyond the ends of the two side plates 22. The protruding part of the base plate 21 is an extension 23 of the base plate 21. When the channel steel frame 2 is installed, the groove of the channel steel frame 2 is aligned with the two door panels and snapped together, so that the edges of the two door panels abut against the bottom of the groove of the channel steel frame 2.

[0005] Structural strength is the most important performance characteristic of air-raid shelter doors. Therefore, high-strength steel is generally selected as the material for all components of air-raid shelter doors. When welding channel steel frames, welders can weld the side plates to both sides of the base plate. However, the structural strength of the welded door frame is insufficient. Therefore, there is a current method for manufacturing channel steel frames, which involves taking a section of high-strength channel steel, cutting off the two side plates of the high-strength channel steel, separating the side plates into two sections, and then separating the two side plates by stamping.

[0006] Regarding the aforementioned technologies, the method of separating the side plates of the stamped channel steel section easily leads to irregular cracks in the separated portion of the side plate and the bottom plate, and also easily causes distortion of the surrounding structure of the separated portion, affecting the structural strength of the channel steel frame. Therefore, it is necessary to design a new channel steel stamping equipment for the manufacture of air-raid shelter doors to overcome the problems existing in the manufacturing of the aforementioned channel steel frames. Summary of the Invention

[0007] In order to improve the structural strength of the channel steel frame while ensuring the production efficiency of the channel steel frame, this application provides a channel steel stamping auxiliary system and its usage method for the manufacture of air defense doors.

[0008] This application provides a channel steel stamping auxiliary system for the manufacture of air-raid shelter doors, employing the following technical solution: A channel steel stamping auxiliary system for manufacturing air-raid shelter doors, comprising a stamping machine, characterized in that: the internal working area of ​​the stamping machine is divided into two parts, namely; The first stamping section is used for stamping steel plates; the second stamping section is used for stamping channel steel sections. In addition, it also includes; A positioning component is provided in the working area of ​​the stamping machine for positioning the steel plate and the channel steel section; A cutting table is set on one side of the stamping machine, on which a cutting blade for limiting the channel steel section slides vertically; The first slide rail connects the first stamping part to one end of the cutting table, and a transport component for conveying the channel steel section is provided on it. The second slide rail connects the second stamping part to one end of the cutting table, and a transport component for conveying the channel steel section is provided on it.

[0009] By adopting the above technical solution, the cutting table and the stamping machine are used as the stamping and processing devices for processing steel plates and channel steel sections in this embodiment. The stamping machine and the cutting table are connected by the first slide rail and the second slide rail to form a complete stamping auxiliary system. With the assistance of the above stamping auxiliary system, the welder greatly improves the production efficiency of channel steel frames in the manufacture of air-raid shelter doors. Unlike traditional stamping machines, in the above solution, the working area of ​​the stamping machine is divided into a first stamping section and a second stamping section. The first stamping section is used to stamp steel plates, that is, the steel plates of appropriate size after cutting are taken and positioned by the positioning components in the working area of ​​the stamping machine, and then the steel plates are extruded into channel steel sections by the first stamping section. The welder then installs the channel steel sections into the first... On the slide rail, the channel steel section is transported to the cutting table via a transport component. At the cutting table, the welder cuts the two side plates of the channel steel section with a cutting blade, dividing each side plate into two parts: one part is the main body, and the other part is adapted to the length of the channel steel frame extension. The welder then transports the cut channel steel section back to the second stamping section via the second slide rail, where the second stamping section stamps the channel steel section. In summary, the stamping machine and stamping table are connected by the conveyor lines of the first and second slide rails to form the entire stamping auxiliary system, thereby reducing the overall labor intensity of the welder. The stamping of the steel plate and the final forming of the channel steel frame can all be carried out through the stamping auxiliary system described above, thus improving the production efficiency of the channel steel frame.

[0010] Optional, also includes; A stamped step block is slidably connected to the second stamping part, and the length of the stamped step block is not less than the length of the channel steel frame extension; The two sides of the bottom of the stamped ladder block are inclined towards the center in the length direction.

[0011] By adopting the above technical solution, the stamping ladder block is a technical feature that distinguishes the second stamping part from the first stamping part. On the cutting table, the welder cuts the two side plates of the channel steel section, separating them into two parts. The cutting depth of the cutting blade on the side plates should be slightly less than the width of the side plates, so that the bottom of the cut groove is as close as possible to the bottom plate. Then, the channel steel section with the side plates cut is conveyed to the stamping table via the second slide rail. The two opposite side walls along the length of the stamping ladder block are inclined towards the center, making its overall shape an inverted trapezoid. The bottom wall of the stamping ladder block remains horizontal. The positioning assembly fixes the channel steel section to the second stamping plate. Afterwards, the stamped ladder block moves down until its bottom wall abuts against the bottom plate of the channel steel section. During this process, the two inclined side walls of the stamped ladder block abut against the two side plates after the channel steel section is cut, and pressure continues to be applied. When the bottom wall of the stamped ladder block abuts against the bottom plate of the channel steel section, the two side plates after cutting are deformed under pressure to adapt to the inclined state of the stamped ladder block. The processed side plates are returned to the cutting table to cut the two inclined side plates. Compared with the traditional stamping separation, the above scheme divides the separation into two steps: stamping and cutting, to avoid the irregular metal separation caused by stamping, which would affect the subsequent processing of the channel steel section.

[0012] Optional, also includes; A table saw, disposed at one end of the cutting table away from the first slide rail, includes two saw blades; The distance between the two saw blades is greater than the width of the channel steel section.

[0013] By adopting the above technical solution, the table saw is used in the final stage of processing the channel steel section into a channel steel frame, that is, the two saw blades are used to cut the two inclined side plates after the above stamping, and separate the inclined part of the side plates. The width of the two saw blades on the table saw is equal to the width of the channel steel section.

[0014] Optionally, both the first slide rail and the second slide rail are slidably connected to a slide plate, and the top side of the slide plate is provided with a structure for engaging the slotted steel section; The ends of both the first and second slide rails near the cutting table are perpendicular to the length direction of the cutting table.

[0015] By adopting the above technical solution, the first and second slide rails are used for transporting the channel steel section between the cutting table and the stamping machine. In the above solution, both the first and second slide rails are bridge structures, and each consists of two independent but parallel guide rails. The slide plates are slidably connected to the guide rails. Furthermore, multiple slide plates should be slidably connected to the guide rails through rollers adapted to the guide rail structure. Above the slide plates is a structure adapted to the main body of the channel steel section, which can be a trough structure. The trough structures on the first and second slide rails form an area for fixing the channel steel section. The welder places both ends of the channel steel section on the two slide plates of the first or second slide rail respectively to achieve fixation during transportation. In addition, in the above solution, considering stability, the design of the first and second slide rails should avoid curved structures and keep them as straight as possible, especially the part near the cutting table should be perpendicular to the length direction of the cutting table. The channel steel section should always remain parallel to the length direction of the cutting table before and after being transported to the cutting table.

[0016] Optionally, the cutting table surface is provided with a cutting groove along the length direction, and a limiting frame is slidably connected in the cutting groove; The internal width of the limiting frame is adapted to the width of the channel steel section, and the cutting table surface is provided with a limiting groove for guiding the sliding of the limiting frame; The length direction of the limiting groove is perpendicular to the length direction of the cutting groove, so that the limiting frame limits the groove steel section along the length direction of the cutting groove. The cutting groove is equipped with a limiting component for positioning the channel steel section.

[0017] By adopting the above technical solution, both the limiting frame and the limiting component are used in the initial cutting process of the channel steel section. During this process, the welder needs to operate the cutting blade to cut the two side plates of the channel steel section sequentially. The limiting component is used for positioning in the length direction of the channel steel section, and the limiting frame is used for positioning the side to be cut in the width direction. Considering that the cutting blade is a circular saw blade with an arc-shaped bottom edge, to ensure the cutting effect of the two side plates, both side plates should be positioned directly below the center of the circular saw blade during cutting. In the above solution, the limiting frame assists the welder in positioning the side plates within the width of the cutting groove. Positioning in the degree direction; firstly, a limiting groove is opened on the cutting table for guiding the limiting frame to realize the forward movement of the limiting frame. The limiting frame is equipped with a handle for the welder to push and pull back and forth. The limiting frame moves back and forth along the width direction of the cutting groove until the side wall of the channel steel section abuts against the wall of the cutting groove. The cutting groove is used to limit the cutting edge. When one side plate of the channel steel section abuts against the cutting groove, the other side plate of the channel steel section is located below the cutting blade. This is how the channel steel section is cut. The cutting method has no impact on the bottom plate of the channel steel section body, ensuring the structural strength of the channel steel frame.

[0018] Optionally, the height of the portion of the first slide rail and the second slide rail that connects to the cutting table is flush with the height of the bottom wall of the cutting groove; The cutting groove sidewall is provided corresponding to the openings of the first slide rail and the second slide rail.

[0019] By adopting the above technical solution, it is convenient for the welder to slide the channel steel section on the first guide rail into the cutting groove of the cutting table, and to slide the channel steel section with the inner side plate of the cutting groove cut into the second guide rail. After the height is aligned, the welder does not need to carry it from the guide rail, but can directly remove the channel steel section from the fixed structure at the top of the slide plate and then slide it into the cutting groove.

[0020] Optional, also includes; The first pushing member is disposed on the inner sidewall of the first stamping part and the second stamping part, and is used to push the channel steel section in opposite directions; The second pushing member is disposed on the side of the first stamping part away from the first slide rail, and cooperates with the first pushing member to push the channel steel section toward the first slide rail.

[0021] By adopting the above technical solution, the first pusher is used to push the channel steel segments to slide towards each other, and to adjust the channel steel segments after stamping so that the channel steel segments are aligned with the first slide rail and the second slide rail on the stamping machine. The second pusher is used to push the channel steel segments out of the stamping machine after the first pusher pushes the channel steel segments to align with the first slide rail, so as to realize the channel steel segments being transported out of the stamping machine.

[0022] Another aspect of this application provides a method for using a channel steel stamping auxiliary system for the manufacture of air-raid shelter doors, comprising the following steps: A method for using a channel steel stamping auxiliary system for the manufacture of air-raid shelter doors, characterized in that: The first stamping section of the stamping machine stamps the steel plate into channel steel segments. With the assistance of the first and second pushers, the welder installs the channel steel segments onto the slide plate of the first slide rail. The welder slides the channel steel section along the length of the cutting groove, and with the help of the limiting component, aligns the cutting position of the channel steel section with the cutting blade. The limiting frame is slid until one side plate of the channel steel section abuts against the inner side wall of the cutting groove, and the cutting blade moves down to cut one side plate of the channel steel section. The limiting frame is slid to the other side plate of the channel steel section to abut against the other side wall of the cutting groove, and the cutting blade moves down to cut one side plate; The welder installs the channel steel section in the cutting groove onto the slide plate of the second slide rail, and uses the second slide rail to transport it to the second stamping part of the stamping machine. The welder then operates the stamping ladder block to move down, causing the side plate of the extended portion of the cut channel steel section to tilt. With the assistance of the first and second pushers, the cut channel steel segment is transported back to the cutting table via the second slide rail. The welder then feeds the channel steel segment in the cutting groove toward the table saw until the saw blade cuts the inclined side plates on both sides.

[0023] By adopting the above steps, the welder completes the mass production of the channel steel frame by operating the above-mentioned stamping auxiliary system; the welder at the stamping machine assists in conveying the channel steel section at the connection between the stamping machine and the first slide rail, and the stamping machine and the second slide rail; the welder at the cutting table conveys the channel steel section from the first slide rail and the second slide rail to the cutting table and assists in cutting.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The traditional stamping method is replaced by cutting and separating, which avoids impact on the channel steel section and protects the structure from structural damage during the manufacturing process of the channel steel frame; 2. The stamping machine and the cutting table are combined by the first and second slide rails to form a stamping auxiliary system that assists welders in welding and cutting, thereby improving the production efficiency of channel steel frames; 3. The conveying mechanism via the first and second slide rails reduces the labor intensity of welders. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 2-11 This application will be described in further detail.

[0038] This application discloses a channel steel stamping auxiliary system and its usage method for manufacturing air defense doors.

[0039] This application first discloses an auxiliary system for stamping channel steel in the manufacture of air-raid shelter doors, referring to... Figure 2 A channel steel stamping auxiliary system for manufacturing air defense doors includes a stamping machine 3 and a cutting table 5 disposed on one side of the stamping machine 3. A first slide rail 4 and a second slide rail 6 are provided between the stamping machine 3 and the cutting table 5 to connect the two. The first slide rail 4 and the second slide rail 6 are respectively disposed on both sides of the stamping machine 3.

[0040] This embodiment adopts a cutting-stamping-cutting technical solution instead of the traditional channel steel stamping separation technical solution. That is, the channel steel section 1 is first cut on the cutting table 5 to separate the main body of the side plate 22 from the corresponding extension of the side plate 22. Then, the side plate 22 of the extension of the channel steel section 1 is stamped by the stamping machine 3 until it protrudes from the main body of the channel steel section 1. Finally, it is transported to the cutting table 5 to cut the stamped side plate 22.

[0041] Based on the above stamping process, the stamping machine 3 is used to stamp the channel steel section 1, and the cutting table 5 is equipped with a cutting component for cutting the channel steel section 1. The first slide rail 4 and the second slide rail 6 are both used to transport the channel steel section 1 between the stamping machine 3 and the cutting table 5. In order to improve the conveying efficiency and to avoid the inability to achieve the function of a single slide rail, two slide rails are set in this embodiment, which are used for the forward and reverse conveying of the channel steel section 1 between the stamping machine 3 and the cutting table 5, respectively.

[0042] Reference Figure 3In this embodiment, the internal working area of ​​the stamping machine 3 is divided into two parts, namely the first stamping part 31 and the second stamping part 32. The top of the stamping machine 3 body is provided with stamping blocks corresponding to the first stamping part 31 and the second stamping part 32. For easy distinction, the stamping block in the first stamping part 31 is the first stamping block 311, and the stamping block in the second stamping part 32 is the second stamping block 321. The top of the stamping machine 3 body is provided with a hydraulic cylinder 34 for driving the first stamping block 311 and the second stamping block 321 to drive the two stamping blocks to move down for stamping.

[0043] Reference Figure 3 and Figure 4 In this embodiment, a plurality of positioning pins 33 are respectively provided in the first stamping part 31 and the second stamping part 32. The plurality of positioning pins 33 are vertically arranged and distributed along the edges of the first stamping part 31 and the second stamping part 32. The plurality of positioning pins 33 form the processing area of ​​the channel steel section 1, thereby achieving the function of limiting the edge of the channel steel section 1. The bottom of the positioning pin 33 is inserted into the inside of the stamping machine 3. A small pneumatic push rod for vertical sliding of the positioning pin 33 is provided inside the stamping machine 3, so that during the stamping process, the small pneumatic push rod inside the machine body pushes the positioning pin 33 upward and protrudes from the inner bottom wall of the stamping machine 3, thereby preventing the channel steel section 1 from deviating from the working area of ​​the first stamping part 31 and the second stamping part 32.

[0044] In this embodiment, the first stamping part 31 is used to stamp the steel plate. When the positioning pin 33 extends and retracts into the machine body, the steel plate is placed in the first stamping part 31. Then, multiple positioning pins 33 of the first stamping part 31 extend synchronously, limiting the steel plate in the first stamping part 31. Then, the first stamping block 311 moves down to abut against the steel plate, squeezing the corresponding part of the steel plate into the stamping groove of the stamping machine 3 to achieve shaping. Since the stamping principle and stamping structure of the stamping machine 3 are common technologies, they will not be described in detail in this embodiment.

[0045] Reference Figure 3 and Figure 4 The stamping machine 3 has a first push cylinder 36 horizontally arranged on the two opposite inner side walls of the first stamping part 31 and the second stamping part 32. The piston rod of the first push cylinder 36 is coaxially arranged. The piston rod ends of the two first push cylinders 36 are fixedly connected to a vertically arranged first push plate 361. The first push cylinder 36 extends the piston rod and pushes the first push plate 361 to slide towards each other. After the steel plate is stamped into channel steel section 1, the first push plate 361 can push the channel steel section 1 to slide towards the center of the stamping machine 3.

[0046] Reference Figure 2 and Figure 3In this embodiment, the first slide rail 4 is connected to the first stamping part 31 of the stamping machine 3 at one end near the stamping machine 3. A connecting plate 35 is provided on the side wall of the stamping machine 3 corresponding to the first slide rail 4. One side of the connecting plate 35 is fixed to the side wall of the stamping machine 3, and the other side of the connecting plate 35 protrudes from the body of the stamping machine 3 and is inclined downward. The downward inclined side of the connecting plate 35 extends to the first slide rail 4. The width of the connecting plate 35 is greater than the length of the channel steel section 1. The stamped channel steel section 1 is transferred to the first slide rail 4 through the connecting plate 35 and conveyed to the cutting table 5.

[0047] Reference Figure 2 and Figure 3 In this embodiment, a second pushing cylinder 37 is horizontally arranged on the side of the stamping machine 3 away from the first slide rail 4. The cylinder body of the second pushing cylinder 37 is fixedly connected to the side wall of the stamping machine 3. A vertically arranged second pushing plate 371 is fixedly connected to the end of the piston rod of the second pushing cylinder 37, and the second pushing plate 371 is directly opposite the center position of the connecting plate 35. After the first pushing cylinder 36 has completed its operation, the second pushing cylinder 37 extends its piston rod and pushes the end of the channel steel section 1 toward the connecting plate 35, assisting the welder in transferring the stamped channel steel section 1 onto the first slide rail 4.

[0048] Therefore, the principle of the first stamping section 31 is briefly described as follows: The welder installs the steel plate between multiple positioning pins 33 of the first stamping part 31. The first stamping block 311 moves down to stamp the steel plate into a channel steel section 1. Then, the positioning pins 33 move down to their tops and are flush with the bottom wall of the stamping part, thus removing the restriction on the channel steel section 1. Then, the first push cylinder 36 extends its piston rod to push the channel steel section 1 to align with the connecting plate 35 of the first slide rail 4. The second push cylinder 37 then extends its piston rod and pushes the channel steel section 1 onto the first slide rail 4 via the second push plate 371, assisting the welder in completing the conveying of the channel steel section 1.

[0049] Reference Figure 2 The first slide rail 4 includes two parallel guide rails, both of which adopt a bridge-type structure. One end of the first slide rail 4 extends to the bottom of the connecting plate 35 of the stamping machine 3, and the other end is connected to the cutting table 5. In this embodiment, the length direction of the end of the first slide rail 4 near the stamping machine 3 is perpendicular to the side of the connecting plate 35 that is inclined downwards, and the length direction of the end of the first slide rail 4 near the cutting table 5 is perpendicular to the side wall of the cutting table 5. Thus, the two ends of the first slide rail 4 are at a preset angle, and the middle section of the first slide rail 4 has a circular arc structure to transition and connect the two ends, so as to ensure the stable turning of the channel steel section 1.

[0050] Reference Figure 2 and Figure 5In this embodiment, each guide rail of the first slide rail 4 is slidably connected to a slide plate 41. The slide plate 41 has a rectangular surface, and the width direction of the slide plate 41 is parallel to the tangent direction of the first slide rail 4. The width of the slide plate 41 is adapted to the width of the channel steel section 1. Vertically arranged side plates are fixed to the opposite side edges of the slide plate 41 along the length direction of the first slide rail 4. The side plates and the individual slide plate 41 form a first conveying groove 42 for engaging the channel steel section 1. In this embodiment, I-beam wheels are rotatably connected to the bottom sides of the slide plate 41. The internal groove of the I-beam wheel is adapted to the width of a single guide rail of the first slide rail 4. In this embodiment, the I-beam wheel is driven by the welder. In other embodiments of this embodiment, a micro motor for driving the rotation of the I-beam wheel can be provided on the bottom side of the slide plate 41 to realize the active rotation of the I-beam wheel and further reduce the labor intensity of the welder.

[0051] The welder places both ends of the channel steel section 1 in the two first conveying grooves 42 above the first slide rail 4, and the channel steel section 1 is stably conveyed by the first conveying grooves 42 whose width is adapted to the width of the channel steel section 1.

[0052] Looking back Figure 2 In this embodiment, the length of the cutting table 5 is greater than its width, and it is elongated.

[0053] It should be noted that, in this embodiment, for ease of demonstration, the cutting table 5 is located on one side of the stamping machine 3, and the two are connected by a first slide rail 4 and a second slide rail 6 of limited length. In other embodiments of this application, if the cutting table 5 is close to the stamping machine 3, there is no need to establish a conveyor line using the first slide rail 4 and the second slide rail 6; the welder can directly handle it. If the cutting table 5 is far from the stamping machine 3, the first slide rail 4 and the second slide rail 6 need to be lengthened to a suitable length. To reduce the design cost of the stamping auxiliary system in this embodiment, the two ends of the first slide rail 4 and the second slide rail 6 should be perpendicular, that is, the length direction of the cutting table 5 should be perpendicular to the side length direction of the connecting plate 35 on the body of the stamping machine 3.

[0054] Reference Figure 2 Based on the above description, in this embodiment, the length of the straight section of the first slide rail 4 near the cutting table 5 is greater than the length of the straight section near the stamping machine 3, so that the channel steel section 1 remains parallel to the length direction of the cutting table 5 before being conveyed to the cutting table 5.

[0055] Reference Figure 6The cutting table 5 has a cutting groove 51 on its surface. The length direction of the cutting groove 51 is parallel to the length direction of the cutting table 5. The cutting groove 51 is the processing area for cutting the channel steel segment 1 and is used to place the channel steel segment 1. A cutting blade is provided on one side of the cutting table 5. In this embodiment, the cutting blade is a metal cutting circular saw, and the blade is a circular saw blade 52. To facilitate the welder's operation and not obstruct the welder's view, the fixing point of the cutting blade on the cutting table 5 is set on the side of the cutting table 5 that connects the first slide rail 4 and the second slide rail 6, so that the handle of the cutting blade faces the welder's standing side. Thus, in this embodiment, the function of the cutting table 5 is to perform the initial cutting of the channel steel segment 1 stamped by the stamping machine 3, separating the two side plates 22 of the channel steel segment 1 corresponding to the body of the channel steel segment 1 and the part corresponding to the extension of the channel steel segment 1, respectively.

[0056] Reference Figure 5 and Figure 6 Based on the above welding operation process, the part of the wall of the cutting groove 51 corresponding to the first slide rail 4 is set to open towards the first slide rail 4, and the bottom height of the cutting groove 51 is consistent with the side plate height of the first conveying groove 42, so that after the first slide rail 4 drives the channel steel section 1 to be conveyed to the cutting table 5, the welder can take the channel steel section 1 out from the first conveying groove 42 and slide it into the cutting groove 51.

[0057] Reference Figure 6 and Figure 7 Based on the cutting principle of the channel steel segment 1 described above, firstly, the welder needs to determine the cutting position along the length of the channel steel segment 1. Secondly, the welder needs to cut the side plates 22 on both sides of the channel steel segment 1 sequentially. Considering that a circular saw blade 52 is used in this embodiment, and the bottom of the groove of the circular saw blade 52 is arc-shaped, in order to ensure the cutting effect, the welder needs to process the side plates 22 of the channel steel segment 1 sequentially, aligning one side plate 22 with the bottom part of the circular saw blade 52, and then cut. Next, the channel steel segment 1 is slid along the width direction of the cutting groove 51, aligning the other side plate 22 with the bottom part of the circular saw blade 52, and then cut. Further, the welder needs to align the outer wall of the side plate 22 with the bottom of the circular saw blade 52, so that when the surface of the bottom plate 21 of the channel steel segment 1 contacts the circular saw blade 52, the height of the cut portion of the side plate 22 of the channel steel segment 1 is below the bottom plate 21. Therefore, in this embodiment, the width of the cutting groove 51 should be no less than twice the width of the channel steel segment 1 to achieve the aforementioned adjustment of the width direction of the channel steel segment 1.

[0058] Reference Figure 6 and Figure 8A limiting plate 53 is vertically installed on the side of the cutting table 5 away from the first slide rail 4. The limiting plate 53 is an auxiliary positioning component for the cutting position in the length direction of the channel steel section 1. The length direction of the limiting plate 53 is greater than the width direction of the limiting plate 53, and it is a strip-shaped plate. The length direction of the limiting plate 53 is perpendicular to the length direction of the cutting groove 51, and the length of the limiting plate 53 is greater than the width of the cutting groove 51. The end of the limiting plate 53 away from the cutting blade is rotatably connected to the table surface of the cutting table 5. A rotating pin is rotatably connected to the table surface of the cutting table 5, which is inserted into one end of the limiting plate 53, so that the other end of the limiting plate 53 rotates around the rotating pin. A corner cylinder 531 is vertically installed at the bottom of the cutting table 5. The top of the cylinder body of the corner cylinder 531 is fixed to the bottom wall of the cutting table 5, and the piston rod of the corner cylinder 531 passes through the cutting table 5 and is fixed to the rotating pin. The cutting table 5 has a corresponding rotating pin with a receiving groove for accommodating the limiting plate 53. The receiving groove is connected to the cutting groove 51, and the length of the receiving groove should be equal to the length of the limiting plate 53.

[0059] Therefore, the corner cylinder 531 rotates the piston rod, causing the limiting plate 53 to rotate until the length direction of the limiting plate 53 is parallel to the width direction of the cutting groove 51. The end of the channel steel section 1 near the cutting blade abuts against the limiting plate 53 to achieve positioning in the length direction. The corner cylinder 531 rotates the piston rod, causing the limiting plate 53 to rotate until the surface of the limiting plate 53 abuts against the side wall of the receiving groove, opening the cutting groove 51 and sliding the cut channel steel section 1 out.

[0060] In other embodiments of this application, the opening width of the receiving groove can be adjusted. When the limiting plate 53 rotates to abut against the side wall of the receiving groove, as long as the limiting plate 53 does not protrude from the cutting groove 51 and affect the transport of the channel steel section 1, it is acceptable.

[0061] Looking back Figure 6 Based on the aforementioned limiting plate 53 used for positioning the cut portion along the length of the channel steel segment 1, this embodiment also includes a limiting frame 54 for sequentially positioning the side plates 22 of the channel steel segment 1. The bottom width of the limiting frame 54 is adapted to the width of the channel steel segment 1, and is used to engage the channel steel segment 1. The limiting frame 54 is slidably connected to the cutting table 5 surface along the width direction of the cutting groove 51. The cutting table 5 surface has limiting grooves 541 for the limiting frame 54 on both sides of the cutting groove 51. The limiting grooves 541 communicate with the cutting groove 51, limiting... The slot 541 is set at a preset length corresponding to the two sides of the bottom of the limiting frame 54. The end of the limiting slot 541 away from the fixing point of the cutting knife is provided with a handle. When the limiting frame 54 slides to one end of the limiting slot 541, the limiting frame 54 drives the channel steel section 1 to abut against one side wall of the cutting slot 51. At this time, the other side wall of the channel steel section 1 is located at a suitable cutting position below the cutting knife. The welder pulls the handle, and the limiting frame 54 slides to the channel steel section 1 to abut against the other side wall of the cutting slot 51. The side plate 22 of the channel steel section 1 below the cutting knife is replaced.

[0062] In summary, after the channel steel section 1 enters the cutting groove 51, the welder cuts the two side plates 22 of the channel steel section 1 in sequence through the auxiliary positioning of the limiting plate 53 and the limiting frame 54, thus completing the initial cutting process.

[0063] Reference Figure 9 The second slide rail 6 has a sliding plate 41 and an I-beam wheel of the same structure slidably connected to it. For ease of separate description, the groove structure formed by the sliding plates 41 on the two guide rails of the second slide rail 6 to adapt to the channel steel is the second conveying groove 61. Similar to the connection between the cutting table 5 and the first slide rail 4, in this embodiment, the part of the wall of the cutting groove 51 corresponding to the second slide rail 6 is set towards the opening of the second slide rail 6, and the bottom height of the cutting groove 51 is consistent with the height of the side plate of the second conveying groove. This allows the welder to remove the channel steel section 1 from the first conveying groove 42 and slide it into the cutting groove 51 after the second slide rail 6 drives the channel steel section 1 to be conveyed onto the cutting table 5.

[0064] In this embodiment, the structure and principle of the second conveying groove 61 are the same as those of the first conveying groove 42, and the principle of the second slide rail 6 is the same as that of the first slide rail 4, only the bending direction is opposite to that of the first slide rail 4. In this embodiment, a connecting plate 35 with the same structure and principle is also provided on the slide rail surface of the second slide rail 6 on one side of the press machine 3 to connect the second slide rail 6 and the press machine 3. This application will not elaborate on the above technical features.

[0065] Reference Figure 9 and Figure 10 The welder slides the initially cut channel steel segment 1 onto the second conveying trough 61 and transports it back to the second stamping section 32 of the stamping machine 3. A stamping step block 322 is fixedly attached to one end of the second stamping block 321. The bottom side of the stamping step block 322 is parallel to the top side, and the two opposite sides of the stamping step block 322 in the length direction are inclined towards the center, so that its longitudinal section is an inverted trapezoid. When the channel steel segment 1 is transported to the second stamping section 32, the positioning pin 33 extends out of the bottom wall of the stamping machine 3 to position the channel steel segment 1. The second stamping block 321 moves down, so that the bottom wall of the stamping step block 322 abuts against the bottom wall of the extension of the channel steel segment 1. The inverted trapezoidal structure of the stamping step block 322 is used to squeeze and deform the two side walls of the cut extension into an inclined state to complete the stamping process.

[0066] Reference Figure 10 In this embodiment, a second pushing cylinder 37 is horizontally arranged on the side of the stamping machine 3 away from the second slide rail 6. The cylinder body of the second pushing cylinder 37 is fixedly connected to the side of the machine body corresponding to the second stamping part 32. The piston rod end of the second pushing cylinder 37 is also fixedly connected to a second pushing plate 371, and the surface of the second pushing plate 371 is vertical. After the second stamping block 321 completes the stamping process, the positioning pin 33 is removed from the fixation. The first pushing cylinder 36 and the second pushing cylinder 37 of the second stamping part 32 operate in sequence to assist the welder in transporting the channel steel section 1 from the connecting plate 35 to the second slide rail 6 again, and then transporting it along the second slide rail 6 to the cutting table 5.

[0067] In this embodiment, the cutting process is carried out again after the stamping is completed. The conveying work before the second cutting is carried out through the second slide rail 6. In other embodiments other than this embodiment, the conveying work before the second cutting can be carried out through the first slide rail 4. However, considering that it will increase the cumbersomeness of the welder's operation, and also considering the mass production of the channel steel frame 2, the first stamping part 31 also has steel plates being stamped when the second stamping block 321 is running. The first slide rail 4 will occupy the conveying structure resources and reduce the production efficiency. Therefore, the preferred solution is to use the second slide rail 6.

[0068] Reference Figure 2 and Figure 11 In this embodiment, a table saw 7 is provided on one side of the cutting table 5. The table saw 7 is an industrial-grade metal profile table saw 7. The saw blade of the table saw 7 adopts a double saw blade structure, and both saw blades are circular saw blades 52, which are the same as the cutting blade. The distance between the two circular saw blades 52 is not less than the width of the channel steel section 1. In this embodiment, the table saw 7 is used to cut the channel steel section 1 that is transported back to the cutting table 5 from the second slide rail 6. The two inclined side walls of the channel steel section 1, which are tilted by the impact, are cut off by the two circular saw blades 52 of the table saw 7.

[0069] Reference Figure 2 and Figure 11 The table saw 7 has a receiving box for bulk material collection on the side opposite to the cutting table 5.

[0070] The implementation principle of the channel steel stamping auxiliary system for the manufacture of air-raid shelter doors in this application embodiment is as follows: This embodiment adopts a process of initial cutting - stamping - secondary cutting, instead of the traditional method of stamping and cutting off the side plate 22 of the extension of the channel steel section 1. The solution of this embodiment does not cause structural impact damage to the channel steel section 1, but protects the structure of the channel steel section 1 during the processing by a non-rigid processing method of first deforming and then cutting.

[0071] The cutting table 5 and the stamping machine 3 serve as the stamping and processing devices for processing steel plates and channel steel sections 1 in this embodiment. The stamping machine 3 and the cutting table 5 are connected by the first slide rail 4 and the second slide rail 6 to form a complete stamping auxiliary system, thereby realizing continuous batch production of channel steel sections 1 and improving processing efficiency.

[0072] This embodiment is based on the above-mentioned channel steel stamping auxiliary system for manufacturing air-raid shelter doors. Secondly, it discloses a method for using the channel steel stamping auxiliary system for manufacturing air-raid shelter doors, including the following steps: The welder places the steel plate on the first stamping section 31 of the stamping machine 3, and operates the stamping machine 3 to limit the steel plate by the positioning pin 33. The steel plate is stamped into channel steel section 1 by the stamping machine 3. The welder slides the two slide plates 41 on the first slide rail 4 to abut the connecting plate 35. The first pusher and the second pusher operate in sequence, and the welder slides the channel steel section 1 through the connecting plate 35 onto the slide plate 41 of the first slide rail 4. The welder will slide the first slide rail 4 along the slide plate 41, move the channel steel from the first slide rail 4 to one end of the cutting table 5, and then transport the channel steel section 1 to the cutting table 5; The welder slides the channel steel section 1 along the length of the cutting groove 51, and operates the limit plate 53 to rotate, with one end of the channel steel section 1 abutting against the limit plate 53. The welder slides the limit frame 54 so that one side plate 22 of the channel steel section 1 abuts against the wall of the cutting groove 51, and the cutting blade moves down to cut the other side plate 22 of the channel steel section 1; the limit frame 54 is slid again so that the cut side plate 22 abuts against the wall of the cutting groove 51, and the cutting blade moves down to cut the other side plate 22. The welder slides the slide plate 41 along the second slide rail 6, so that the slide plate 41 abuts against the cutting table 5, installs the channel steel section 1 in the cutting groove 51 onto the slide plate 41 of the second slide rail 6, and slides the second conveying groove 61 toward the stamping machine 3; The welder uses the connecting plate 35 to transport the material to the second stamping section 32 of the stamping machine 3, and operates the stamping ladder block 322 to move it down so that the side plate 22 of the extended part of the cut channel steel section 1 is tilted. With the assistance of the first and second pushers, the cut channel steel section 1 is transported to the cutting table 5 again via the second slide rail 6. The welder then feeds the channel steel section 1 in the cutting groove 51 toward the table saw 7, until the saw blade cuts the inclined side plates 22 on both sides.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
