[0001] This application relates to the field of prefabricated building panel forming technology, and in particular to a forming equipment and process for assembling load-bearing wall panels. Background Technology

[0002] With the development of prefabricated buildings, prefabricated load-bearing wall panels have been widely used due to their high construction efficiency and excellent structural performance. Existing load-bearing wall panels are usually composed of various components such as frame panels, wall panels, beam panels, and box-shaped cover panels. These components have complex geometric cross-sections and require specialized molding equipment.

[0003] The production of these components currently faces the following problems: 1. Each component needs to be produced on different equipment, resulting in dispersed production lines; 2. Manual or semi-mechanized production leads to poor precision and low consistency; 3. Segmented processing is inefficient and cannot meet the needs of large-scale production; 4. The fitting precision between components is difficult to guarantee, affecting the overall assembly quality. Summary of the Invention

[0064] This embodiment provides a molding equipment for assembling load-bearing wall panels. The entire machine is centrally controlled by a central controller, enabling one-button start-up and automatic continuous production. This molding equipment is used for the centralized production of the frame panel 103, Great Wall panel 104, crossbeam 105, and box-shaped cover panel 106 in the wall panel components 10. The molding equipment is divided into four molding production lines: a frame panel molding line, a Great Wall panel molding line, a crossbeam panel molding line, and a box-shaped cover panel molding line. Each molding production line includes:

[0065] The stamping device 1 is equipped with at least one set of stamping dies 11. Each stamping die 11 is equipped with a detachable punch and die pair 12 for punching out different types of hollow parts 101 in the sheet metal. The boundary of the hollow part 101 serves as a clearance area for roll bending, or the edge of the hollow part 101 serves as a positioning line for roll bending, or the retained structure of the hollow part 101 is folded up after roll bending to form a connecting structure. Each set of stamping dies 11 adopts a servo hydraulic press and a quick die changing structure. Each set of stamping dies 11 includes an upper stamping die 13 and a lower stamping die 14. The upper stamping die 13 is driven by a servo hydraulic cylinder, and the lower stamping die 14 is fixed on the stamping worktable.

[0066] The roll forming device 2 has several pairs of upper and lower rotating shafts arranged sequentially along the conveying direction of the sheet material; each upper rotating shaft is fitted with at least one upper convex roller 21 at intervals, and a corresponding lower convex roller 22 is fitted on the lower rotating shaft, the two forming a punch assembly 23; the sheet material is continuously fed between the upper and lower convex rollers 22 and gradually roll-pressed to form the complex cross-section of the wall panel component 10; Reference Figure 4 , 5 (The roller forming device 2 of the skeleton plate forming line is shown in the figure) The roller forming device 2 includes a width adjustable component 24.

[0067] The shearing device 3 is used for online shearing and separation of the wall panel component 10 along the shearing line 30. The shearing line 30 is collinear with the edge of the hollow part 101 in the length direction of the plate or collinear with the geometric center line of the hollow part 101 in the width direction of the plate. The shearing device 3 includes a cutter 31 and a limiting module 32. The limiting module 32 is used to limit the complex cross section of the formed wall panel component 10. The blade profile of the cutter 31 is mirror-matched with the complex cross section of the formed wall panel component 10. The limiting module 32 is provided with a cutting groove 321 for the cutter 31 to cut downward.

[0068] First embodiment, such as Figures 1-9 .

[0069] Provide a skeleton plate forming line, reference Figure 2 The frame panel 103 to be formed has facade assembly plates 1031 at both ends along its length and complex cavities 1032 distributed on both sides along its width. The frame panel 103 is the core component of the wooden frame wall panel, and its surface must be compatible with the installation positions of the Great Wall board and beams according to the design. To this end, the forming line sequentially completes processes such as multi-sided hollow punching, punching of assembly holes and installation bolt holes, cavity rolling, cutting and folding forming, etc., online. The process parameters such as "with / without facade assembly plates 1031" and "hole combination" can be switched in real time on the control interface to realize single-piece customization and batch continuous parallel production.

[0070] refer to Figure 1The sheet material can be continuously supplied by the feeding machine and input into the forming line through the input port of the forming line of the skeleton plate 103 for forming preparation; the forming line is provided with a stamping device 1, a roll forming device 2 and a cutting and folding head device in sequence along the sheet material transportation direction, wherein the cutting and folding head device is a shearing device 3 equipped with a folding head assembly 33, and the roll forming device 2 is used to roll out the cross section of the complex cavity 1032 in one roll along the width direction of the sheet material.

[0071] refer to Figure 3 The stamping device 1 is equipped with three sets of stamping dies 11. In the skeleton plate forming line, the hollowed-out portion 101 punched by the stamping device 1 is either a polygonal hollowed-out portion with a reserved bending area 1011 or a polygonal hollowed-out portion without a reserved bending area 1011. One set of stamping dies 11 is used for this polygonal hollowed-out portion. A detachable punch and die pair 12 is correspondingly set on one set of stamping dies 11. The punch is fixed to the upper stamping die 13, and the die is fixed to the lower stamping die 14. The shape of the punch cutting edge is identical to the shape of the polygonal hollowed-out portion. This die pair can be replaced as a whole through a quick-clamp + positioning pin structure, realizing online switching between two types of polygonal hollowed-out punching: "with / without facade assembly panel 1031".

[0072] The skeleton plate forming line also provides punching for hole combinations and punching for hook structures 1033. The punching of hole combinations utilizes an array of female and male die seats 15 correspondingly set on one set of stamping dies 11. The female die is fixed to the lower stamping die 14, and the male die is fixed to the upper stamping die 13. The male die includes at least one of assembly hole dies, bolt hole dies, and positioning hole dies. The punching of hook structures 1033 utilizes a stamping die 11 with a hook pre-punching die 16 set on one set of stamping dies 11, used to punch cuts on the plate surface that match the edges of hook structures 1033, releasing material for subsequent bending.

[0073] refer to Figures 4-5In the frame plate forming line, the roll forming device 2 includes a width adjustable component 24. The width adjustable component 24 includes a fixed seat 241 and a movable seat 242 mounted on the frame, as well as a drive mechanism. The drive mechanism includes a motor 243 and a screw and nut mechanism 244. The screw and nut mechanism 244 is connected to the movable seat 242 and the motor 243. The motor 243 drives the movable seat 242 to slide left and right, away from or close to the fixed seat 241, through the screw and nut mechanism 244. The forming die group 23 of the roll forming device 2 includes two sets of convex rollers 231 symmetrically arranged along the rotation axis. Each set of convex rollers 231 consists of an upper convex roller 21 and a lower convex roller 22. One set of convex rollers 231 is mounted on the fixed seat 241, and the other set is mounted on the movable seat 242. The distance between the two sets of convex rollers 231 can be adjusted by moving the movable seat 242 relative to the fixed seat 241 to accommodate plates of different widths. It should be noted that the settings for the width-adjustable component 24 can be selectively configured on the other three forming lines according to actual needs.

[0074] In this embodiment, the skeleton plate 103 to be formed will be designed with a hook structure 1033 as required. The hook structure 1033 is located on the bottom surface of the complex cavities 1032 on both sides and bends downward along the bottom surface. Therefore, according to the forming requirements of the hook structure 1033, a set of stamping dies 11 can be used in the stamping device 1 to punch out a cut that matches the edge of the hook structure 1033. Reference Figure 6 A bending device 4 will be added in front of the cutting and bending device along the direction of sheet material transportation.

[0075] refer to Figure 7 The bending device 4 includes an upper bending die 42 driven by a first servo motor 41 and a lower bending die 44 driven by a second servo motor 43. The upper bending die 42 is provided with a pressing bending element 421, and the lower bending die 44 is provided with a corresponding relief cavity 441. When the sheet metal is placed in the bending device 4, the second servo motor 43 drives the lower bending die 44 to move upward and support it below the sheet metal, while the first servo motor 41 drives the upper bending die 42 to move downward. The pressing bending element 421 presses the hook structure 1033 downward into the relief cavity 441 to complete a 90° bend. To avoid transport interference, the lower bending die 44 needs to "rise first and then fall": before the upper bending die 42 moves downward, the lower bending die 44 needs to move upward to support the sheet metal. After bending, the upper and lower dies are removed, and after removal, the sheet metal continues to be transported.

[0076] refer to Figures 8-9, the cutting and end-folding device is a shearing device 3 provided with an end-folding assembly 33. The cutting and end-folding device adopts a servo hydraulic press, a third servo motor 34 drives an upper cutting die 35 to lift up and down, and a fourth servo motor 36 drives a lower cutting die 37 to lift up and down. The lower cutting die 37 needs to "rise first and then fall": before the upper cutting die 35 descends, the lower cutting die 37 needs to rise to support the plate; after cutting, the upper and lower dies are withdrawn, and the plate continues to be transported after die withdrawal. A limiting module 32 that is in position-limiting fit with the cross-section of the formed skeleton plate 103 is arranged on the lower cutting die 37, which is used for plate forming and cutting support.

[0077] Reference Figure 8 , the shearing device 3 comprises a cutting knife 31 arranged on the upper cutting die 35 and a knife groove 321 arranged on the lower cutting die 37. The knife edge contour of the cutting knife 31 is in mirror-image fit with the cross-section of the skeleton plate 103, and a relief notch 311 is recessed in the middle of the knife edge of the cutting knife 31 for avoiding bending of the vertical splicing connecting plate 1031. Reference Figure 9 , pressing blocks 351 are arranged on the upper cutting die 35 at the front and rear sides of the cutting knife 31. When the upper cutting die 35 descends and the cutting knife 31 does not touch the plate, the pressing blocks 351 press the plate first and fit with the limiting module 32 to press and fix the plate.

[0078] the end-folding assembly 33 comprises a folding die 331 arranged on the lower cutting die 37, the folding die 331 is driven by a fifth servo motor to lift up and down relative to the lower cutting die 37, as Figure 9 , a set of folding dies 331 are respectively arranged on the front and rear sides of the knife groove 321. While the cutting knife 31 performs cutting, the folding dies 331 immediately ascend to jack and fold the reserved bending area 1011 at the hollowed edge upward, forming the vertical splicing connecting plate 1031 in one step.

[0079] When the cutting knife 31 of the shearing device 3 completes cutting the plate downward along the shear line 30 instantly, the folding die 331 of the end-folding device immediately ascends to jack and fold the reserved bending area 1011 at the hollowed edge upward, forming the vertical splicing connecting plate 1031 in one step; if the batch of skeleton plates 103 does not need the vertical splicing connecting plate 1031, the end-folding device remains on standby and only performs the cutting function, with flexible switching and no need for die replacement. In this embodiment, each hollowed part 101 takes the geometric center line of the plate width as the symmetric shear line.

[0080] Second embodiment, as Figures 10-13 .

[0081] Provided is a Great Wall plate forming line, reference Figure 11 , the structure of the Great Wall plate 104 to be formed comprises an inverted Ω-shaped continuous corrugated structure 1041 and hook structures 1012 on both sides of the corrugated structure. Reference Figure 10The sheet material can be continuously supplied by a discharger, and is input into the Great Wall plate forming line through the input port of the Great Wall plate forming line for forming preparation; the Great Wall plate forming line is sequentially provided with a stamping device 1, a roll forming device 2 and a shearing device 3 along the sheet material conveying direction. Wherein, the roll forming device 2 is configured to perform continuous rolling on the sheet material to form a Ω-shaped continuous corrugated structure 1041.

[0082] In the Great Wall plate forming line, the hollowed-out part punched by the stamping device 1 is a quadrilateral hollow with a reserved hook structure 1012, and the region where the hollowed-out part is located serves as a transition connection region between every two Great Wall plates 104 to be formed. The punch 121 in the convex-concave die pair 12 provided on the stamping device 1 is symmetrically provided with two hook-shaped notches 123 at the cutting edge, and the two hook-shaped notches 123 are arranged in a front-back mirror image along the sheet material conveying direction; the concave die 122 in the convex-concave die pair 12 provided on the stamping device 1 is provided with a punching groove 124 that matches the contour of the punch 121.

In this embodiment, the spacing L1 between two adjacent punches 121 is equal to the width L2 of one corrugated protruding section of the Ω-shaped continuous corrugated structure 1041, which ensures zero deviation between the punching phase and the corrugation phase, and ensures that the hook structure 1012 is located on the vertical faces 102 on both sides of the corrugated structure after roll forming, as shown in Figure 11 .

[0084] Reference Figure 13 , the shearing device 3 comprises a servo tracking module and a shearing unit, the servo tracking module is composed of a servo motor 38, a linear guide rail and an encoder, which reads the conveying speed of the sheet material in real time and drives the shearing unit to move synchronously with the sheet material, so as to ensure zero relative speed during the shearing process.

[0085] The shearing unit is composed of a cutting knife 31 and a limit module 32, the limit module 32 is fixed on a synchronous sliding table following the shearing device 3, the limit module 32 is provided with a cutting opening 322 and a knife groove 321 matching with the downward movement of the cutting knife 31, the cutting opening 322 is profiled processed according to the Ω-shaped continuous corrugation of the Great Wall plate 104, forming a wavy cutting opening 322 for forming support. The cutting edge contour of the cutting knife 31 is mirror-matched with the cross section of the Great Wall plate 104, and an avoidance notch 311 is provided at the position of the cutting edge of the cutting knife 31 corresponding to the vertical faces 102 on both sides of the corrugated structure, as shown in Figure 13. The cutting knife 31 is arranged on a follow-up seat 39, and the follow-up seat 39 is driven by a servo motor 38 to move up and down quickly.

The connecting portion is the retaining strip between adjacent hollowed-out portions and the retaining strip at the edge of the hollowed-out portion, and the shear line 30 is an edge connecting line with the hook structure 1012 on a plurality of said hollowed-out portions 101.

[0086] Third embodiment, see Figures 14-17 .

[0087] Provided is a cross beam plate forming line, with reference to Figure 15 , the cross beam 105 to be formed has a "gable"-shaped structure 1051 in cross section, hook structures 1012 are arranged on both sides of the cross beam 105 along the length direction thereof, and a clamping groove 1052 is opened in the middle of the cross beam 105 along the length direction. The cross beam 105 is used for transversely connecting a Great Wall-shaped plate 104 and a framework plate 103, so the hook structure 1012 and the clamping groove 1052 are simultaneously arranged on the cross beam 105. The clamping groove 1052 is used for forming clamping fit with correspondingly arranged hook structures on the Great Wall-shaped plate 104 respectively, so as to realize rapid positioning and reliable connection between components.

[0088] With reference to Figure 14 , the plate material can be continuously supplied by a uncoiler and input into the forming line through an input port of the forming line for forming preparation; the cross beam plate forming line is sequentially provided with a stamping device 1, a roll forming device 2 and a shearing device 3 along the plate material conveying direction. Wherein, the roll forming device 2 is configured to perform continuous rolling on the plate material to form the "gable"-shaped structure 1051.

The length of the vertical side is greater than the length of the horizontal side. The stamping device 1 is set with two sets of punch and die pairs along the width direction of the plate. The two sets of punch and die pairs punch out two symmetrical T-shaped relief notches 1013 on both sides of the width direction of the plate.

[0102] This embodiment provides a molding process for assembling load-bearing wall panels, using a molding device for assembling load-bearing wall panels provided in this embodiment; the molding process includes:

[0103] Step 1: Uncoiling and pretreatment of sheet material. The sheet material is continuously supplied to the integral forming line by the unloading machine that carries the sheet material roll. Before entering the stamping device 1, the sheet material is first covered with a protective film by the upper and lower film covering devices 5, and then the sheet material is flattened by multiple sets of flattening pressure rollers by the leveling device 6.

[0104] Step 2: The stamping device 1 punches the panel surface. According to the type of wall panel component 10, the corresponding stamping module 11 is set to punch out the corresponding type of hollow part 101 in the panel surface.

[0105] Step 3: The sheet material is formed by the roll forming device 2. The complex cross section of the wall panel component 10 is gradually formed by multiple roll forming through multiple sets of punches 23.

[0106] Step 4: The shearing device 3 is used for online shearing and separation of the wall panel component 10 along the shearing line 30; In step 4, the corresponding folding head assembly 33 or front and rear bending device 7 is set according to the type of wall panel component 10, and in conjunction with the cutting of the shearing device 3, the cut side of the board is bent upward.

[0107] Step 5: Output of finished wall panel component 10.

[0108] refer to Figure 25 The assembly of the finished wall panel component 10 is as follows:

[0109] The first step involves splicing four frame panels 103 in pairs to form a rectangular frame. Two of the four frame panels 103 have facade assembly joint plates 1031, while the other two do not. Holes are made in the facade assembly joint plates 1031. Holes are also made in the frame panels 103 without facade assembly joint plates 1031 at the positions where they are spliced ​​with the facade assembly joint plates 1031. The structure of the facade assembly joint plates 1031 is used to achieve the splicing of the four frame panels 103 in pairs.

[0110] The second step is to splice the crossbeam 1 with the frame plate 103 through the hook structure 1012. The frame plate 103 has a slot 1052 at the position for splicing with the crossbeam 105. By using the cooperation of the slot 1052 and the hook structure 1012, the crossbeam 105 is spliced ​​on the rectangular frame formed by the frame plate 103.

[0111] The third step involves splicing the Great Wall panel 104 to the frame panel 103 using the hook structure 1012. The frame panel 103 has slots 1052 at the points where it will be spliced ​​with the Great Wall. The crossbeam 105 is then spliced ​​onto the rectangular frame formed by the frame panel 103 by the cooperation of the slots 1052 and the hook structure 1012. Alternatively, the Great Wall panel 104 can be spliced ​​to the crossbeam 105 using the slots 1052 provided on the crossbeam.

[0112] The fourth step is to place the box-shaped cover plate 106 on both ends of the rectangular frame formed by the skeleton plate 103, thus forming the structure of the load-bearing wall panel.
