Description

Technical Field

[0001] The invention relates to the technical field of modular integrated house frame skin assembly, and more specifically to an edge wrapping device. Background Art

[0002] In recent years, the national and local governments have successively issued a series of policies to promote prefabricated buildings, clearly requiring the assembly rate of new buildings. Various companies have successively carried out research on prefabricated buildings and completed some preliminary research and engineering cases of prefabricated buildings. Modular integrated houses are a form of building with a high degree of prefabrication that conforms to the form of prefabricated buildings. This type of building is a building structure that uses a single room as a prefabricated component unit, which is prefabricated in the factory and then transported to the construction site for installation. The development history of integrated houses in my country is relatively short and the development speed is relatively slow. A large number of processes in prefabricated production factories are carried out manually, with a low degree of automation and uneven product quality.

[0003] At present, some modular integrated house frame products are 6m long and 3m wide. The skinning and edging are done manually, which has low work efficiency. The skinning and edging of a single frame requires the cooperation of 3-4 people, and the completion speed is 8-9 minutes or even longer. The edging is done manually using shovel-type tools to push, smash and warp. The skinning accuracy is low, the flange lengths are uneven, the skinning is easy to tear, the skinning effect is average, and the labor cost is high. Summary of the invention

[0004] The purpose of the present invention is to provide an edge wrapping device to solve the technical problems of slow edge wrapping speed, low precision, poor effect and high labor cost of modular integrated house frames in the prior art.

[0005] To achieve the above object, the technical solution adopted by the present invention is a hemming device, comprising:

[0006] Bracket;

[0007] A mobile assembly platform, used to move the skin and the frame to an installation position, wherein the skin is placed on a position of the frame to be hemmed, and the frame has a first edge and a second edge adjacent to the first edge;

[0008] A first pressing, clamping and edging module is movably connected to the bracket, the first pressing, clamping and edging module can move along the first side of the frame, the first pressing, clamping and edging module comprises a first side stamping module and a first side clamping module, the first stamping end face of the first side stamping module is used to stamp the edge of the skin to form a first edging wrapped around the first side of the frame, the first side clamping module is arranged on a side of the first side stamping module close to the second pressing, clamping and edging module, and the first side clamping module is used to clamp the first edging after stamping;

[0009] A second pressing, clamping and edging module is movably connected to the bracket, and the second pressing, clamping and edging module can move along the second side of the frame. The second pressing, clamping and edging module includes a second side stamping module group and a second side clamping module group. The second stamping end face of the second side stamping module group is used for stamping the skin edge to form a second edging wrapped around the second side of the frame.

In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The specific implementation of the present invention is described in more detail below in conjunction with specific embodiments:

[0052] like Figure 1 As shown, an edge wrapping device 100 provided by an embodiment of the present invention comprises: a bracket 1, a mobile assembly platform 2, a first pressing and clamping edge wrapping module 3 and a second pressing and clamping edge wrapping module 4. The bracket 1 is used to be placed on a fixed plane and is placed horizontally; the mobile assembly platform 2 is used to move the skin 5 and the frame 6 to the installation position, and the skin 5 is placed on the position of the frame 6 to be edge wrapped. Please refer to Figures 2 to 5 The frame 6 has a first side 61 and a second side 62 adjacent to the first side 61; the first pressing and clamping edge wrapping module 3 is movably connected to the bracket 1, and the first pressing and clamping edge wrapping module 3 can move along the first side 61 of the frame 6, such as Figure 6 and Figure 7 As shown, the first pressing and clamping edge wrapping module 3 includes a first edge stamping module group 31 and a first edge clamping module group 32. The first stamping end face 311 of the first edge stamping module group 31 is used to stamp the skin edge 51 to form a first edge wrapped on the first edge 61 of the frame 6. The first edge clamping module group 32 is arranged on a side of the first edge stamping module group 31 close to the second pressing and clamping edge wrapping module 4. The first edge clamping module group 32 is used to clamp the first edge after stamping. The second pressing and clamping edge wrapping module 4 is movably connected to the bracket 1. The second pressing and clamping edge wrapping module 4 can move along the second side 62 of the frame 6, and the second pressing and clamping edge wrapping module 4 includes a second side stamping module 41 and a second side clamping module 42. The second stamping end face 411 of the second side stamping module 41 is used to stamp the skin edge 51 to form a second edge wrapped on the second side 62 of the frame 6. The second side clamping module 42 is arranged on the side of the second side stamping module 41 close to the first pressing and clamping edge wrapping module 3, and the second side clamping module 42 is used to clamp the second edge after stamping.

[0053] The working principle of the hemming device 100 provided in this embodiment is as follows:

[0054] The mobile assembly platform 2 is used to move the skin 5 and the frame 6 to the installation position. Specifically, the skin 5 is placed on the frame 6, and the edge 51 of the skin is exposed outside the edge of the frame 6 (the skin 5 can be a planar structure, or the edge 51 of the skin can be tilted downward at 15° with the plane where the skin 5 is located according to production requirements, or tilted at other angles. In this embodiment, the skin 5 is a 0.3 mm thick galvanized steel plate). The mobile assembly platform 2 moves the stacked skin 5 and the frame 6 to the installation position. In this embodiment, the installation position is below the bracket 1; the frame 6 has a first side 61 and a second side 62 adjacent to the first side 61, the first side 61 and the second side 62 intersect at an acute angle, a right angle or an obtuse angle, and the length of the first side 61 and the length of the second side 62 are not limited. In this embodiment, the first side 61 and the second side 62 intersect at an obtuse angle, and the length of the first side 61 is much greater than the length of the second side 62. That is, the first side 61 is a straight side of the frame 6, and the second side 62 is an angle side of the frame 6;

[0055] When the skin 5 and the frame 6 are moved to the installation position, the first pressing and clamping edge module 3 moves to a position close to the first side 61 of the frame 6, and the first stamping end face 311 of the first side stamping module 31 starts to stamp the skin edge 51, wrapping the skin edge 51 on the first side 61 of the frame 6 to form a first edge wrapped on the first side 61 of the frame 6, and the first side clamping module 32 is used to clamp the first edge after stamping, so that the first edge tightly wraps the first side 61 of the frame 6;

[0056] The second pressing and clamping edge wrapping module 4 moves to a position close to the second side 62 of the frame 6, and the second stamping end face 411 of the second side stamping module 41 starts to stamp the skin edge 51, wrapping the skin edge 51 on the second side 62 of the frame 6 to form a second edge wrapping on the second side 62 of the frame 6. The second side clamping module 42 is used to clamp the stamped second edge wrapping so that the second edge wrapping tightly wraps the second side 62 of the frame 6.

[0057] It needs to be further explained that after the first side clamping module 32 clamps the first edge, the first side clamping module 32 remains in the clamping state, and the first side clamping module 32 is located on the side of the first side stamping module 31 close to the second pressing and clamping module 4, and the second side 62 is arranged adjacent to the first side 61, so that the first side clamping module 32 can fix the first edge to prevent relative displacement between the skin 5 and the frame 6, causing the second side clamping module 42 to clamp the second edge with reduced accuracy and unevenness, thereby causing poor skinning effect; in addition, the first side clamping module 32 remains in the clamping state, and the skin edge 51 on the second side 62 of the frame 6 is driven to flip by the skin edge 51 on the first side 61 of the frame 6, which can also reduce the force required for the second side clamping module 42 to clamp, thereby reducing the difficulty of clamping.

[0058] By adopting the above-mentioned technical scheme, the first press-clamping and edge wrapping module 3 and the second press-clamping and edge wrapping module 4 are movably connected with the bracket 1, and the first press-clamping and edge wrapping module 3 and the second press-clamping and edge wrapping module 4 respectively perform edge wrapping operations on the first side 61 and the second side 62 of the frame 6, and the first stamping end face 311 of the first side stamping module 31 performs preliminary edge wrapping on the first side 61 of the frame 6 by stamping, and its edge wrapping speed is fast; then the first side clamping module 32 clamps the first edge wrapping after stamping, so that it is tightly wrapped on the first side 61 of the frame 6, and its edge wrapping precision is high and the effect is good; similarly, the second stamping end face 411 of the second side stamping module 41 performs preliminary edge wrapping on the second side 62 of the frame 6 by stamping, and at the same time, because the first side clamping module 32 keeps the first side 61 clamped, the edge wrapping speed and edge wrapping precision of the second edge of the frame 6 are further improved; the first press-clamping and edge wrapping module 3 and the second press-clamping and edge wrapping module 4 work together to greatly reduce the labor cost.

[0059] like Figure 8 As shown, in one embodiment, the first pressing and clamping edge wrapping module 3 includes a plurality of first edge stamping dies 31 , and angles formed between the first stamping end faces 311 of the plurality of first edge stamping dies 31 and the plane where the frame 6 is located increase in sequence.

[0060] Specifically, the skin 5 is a planar structure (or a preset angle is formed between the skin edge 51 and the skin 5), and the skin edge 51 is wrapped around the frame 6, that is, the skin 5 is placed on the upper side of the frame 6, and then the skin edge 51 is flipped over and attached to the lower side of the frame 6 to achieve the edging of the frame 6. The angles of the first stamping end faces 311 of multiple first side stamping modules 31 increase sequentially. When the first first side stamping module 31 stamps the skin edge 51, the skin edge 51 flips toward the skin 5 by a first preset angle. When the second first side stamping module 31 stamps the skin edge 51, the skin edge 51 flips toward the skin 5 by a second preset angle. When the third first side stamping module 31 stamps the skin edge 51, the skin edge 51 flips toward the skin 5 by a third preset angle, and so on. The preset angles increase sequentially, and the flipping angle of the skin edge 51 becomes larger and larger until the skin edge 51 is wrapped around the frame 6.

[0061] By adopting the above technical solution, a plurality of first side stamping dies 31 with increasing angles successively flip the skin edge 51 , thereby preventing the skin edge 51 from flipping too large an angle in one stamping, thereby causing the skin 5 to rupture.

[0062] In one embodiment, the first pressing and edge wrapping module 3 includes three first edge stamping dies 31 , and the angles of the three first stamping end faces 311 are 45°, 90° and 135° respectively.

[0063] Specifically, the angle of the first first side punching die set 31 is 45°, the angle of the second first side punching die set 31 is 90°, and the angle of the third first side punching die set 31 is 135°.

[0064] By adopting the above-mentioned technical solution, the angles of multiple first edge stamping modules 31 are increased in increments of 45°, thereby preventing the skin edge 51 from flipping over too large an angle during one stamping, thereby causing the skin 5 to rupture. In addition, while maintaining the integrity of the skin 5 during flipping, the number of stamping times is reduced, thereby ensuring the speed of hemming.

[0065] like Fig. 9 As shown, in one embodiment, the angle formed by the second stamping end surface 411 of the second side stamping die set 41 and the plane where the frame 6 is located is 90°.

[0066] Specifically, the first side 61 and the second side 62 of the frame 6 are arranged adjacent to each other. When the edge of the skin 5 located at the first side 61 of the frame 6 is clamped, the edge of the skin 5 located at the second side 62 of the frame 6 will be flipped, thereby forming a skin edge 51 with an initial angle. Therefore, the second stamping end face 411 of the second side stamping die set 41 can be set to 90°, saving one stamping operation.

[0067] By adopting the above technical solution, at least one stamping operation is saved, thereby improving the hemming efficiency of the second side 62 of the frame 6 .

[0068] Please refer again Figure 6 and Figure 8 In one embodiment, the first pressing and clamping module 3 includes a first edge pressing module 33, which can move in a direction perpendicular to the plane where the frame 6 is located, and the pressing end surface 331 of the first edge pressing module 33 is used to press the skin 5 onto the frame 6.

[0069] Specifically, the skin 5 is a planar structure, and the skin 5 is placed on the frame 6, and the first side clamping module 33 moves in a direction perpendicular to the plane where the frame 6 is located until the clamping end face 331 of the first side clamping module 33 presses the skin 5 onto the frame 6.

[0070] By adopting the above technical solution, the pressing end surface 331 presses the skin 5 to prevent it from moving or bulging when its edge is bent, causing the hemming accuracy to decrease or fail.

[0071] In one embodiment, the first pressing and clamping edge wrapping module 3 also includes a first side moving module 34 connected to the first side stamping module 31 and the first side clamping module 32, the first side moving module 34 includes a first moving connecting plate 341, a second moving connecting plate 342, a first moving driving member 343 and a second moving driving member 344, the first moving connecting plate 341 is slidably connected to the bracket 1, the first moving driving member 343 is used to drive the first moving connecting plate 341 to move along the first side 61 of the frame 6, the second moving connecting plate 342 is slidably connected to the first moving connecting plate 341, and the second moving driving member 344 is used to drive the second moving connecting plate 342 to move in a direction perpendicular to the plane where the frame 6 is located.

[0072] Specifically, the length of the first side 61 of the frame 6 is greater than the length of the first side stamping die set 31, and the first side stamping die set 31 is driven to move by the first side moving die set 34 to perform edging on each part of the first side 61 of the frame 6 one by one; in addition, the first side moving die set 34 includes a first moving connecting plate 341 and a second moving connecting plate 342, so that the first side stamping die set 31 can move along the first side 61 of the frame 6, and can also move in a direction perpendicular to the plane where the frame 6 is located.

[0073] By adopting the above-mentioned technical solution, the first side stamping die set 31 can perform hemming on each part of the first side 61 of the frame 6 one by one, or perform hemming on a part of the first side 61 of the frame 6 as required; in addition, the first side stamping die set 31 can move along the first side 61 of the frame 6, and can also move in a direction perpendicular to the plane where the frame 6 is located. It has high movement flexibility and is suitable for hemming operations on frames 6 of different heights.

[0074] Please refer again Figure 7 In one embodiment, the second pressing and clamping edge wrapping module 4 also includes a second side moving module 43 connected to the second side stamping module 41 and the second side clamping module 42, the second side moving module 43 includes a third moving connecting plate 431, a fourth moving connecting plate 432, a third moving driving member 433 and a fourth moving driving member 434, the third moving connecting plate 431 is slidably connected to the bracket 1, the third moving driving member 433 is used to drive the third moving connecting plate 431 to move in a direction close to the frame 6, the fourth moving connecting plate 432 is slidably connected to the third moving connecting plate 431, and the fourth moving driving member 434 is used to drive the fourth moving connecting plate 432 to move in a direction perpendicular to the plane where the frame 6 is located.

[0075] Specifically, the length of the second side 62 of the frame 6 is much smaller than the length of the first side 61, and the second side stamping die set 41 does not need to move along the second side 62 of the frame 6. It only needs to move the second side stamping die set 41 to a position close to the second side 62 of the frame 6; the second side moving die set 43 includes a third moving connecting plate 431 and a fourth moving connecting plate 432, so that the second side stamping die set 41 can be close to the second side 62 of the frame 6, and can also move in a direction perpendicular to the plane where the frame 6 is located.

[0076] By adopting the above technical solution, the second side stamping die set 41 can be close to the second side 62 of the frame 6, and can also move in a direction perpendicular to the plane where the frame 6 is located. It has high movement flexibility and is suitable for edge wrapping operations on frames 6 of different heights.

[0077] Please refer again Figure 8 In one embodiment, the first side stamping die set 31 includes a first side stamping connecting plate 312, a first side stamping head 313 and a first side stamping driving member 314, the first stamping end face 311 is formed on the first side stamping head 313, the first side stamping head 313 is slidably connected to the first side stamping connecting plate 312, and the first side stamping driving member 314 drives the first side stamping head 313 to press against the first side 61 of the frame 6.

[0078] Specifically, the first side stamping head 313 is driven by the first side stamping driving member 314 to move toward the first side 61 of the frame 6 until the first stamping end face 311 is pressed against the first side 61 of the frame 6. Since the first stamping end face 311 forms a preset angle with the plane where the frame 6 is located, the first stamping end face 311 bends the skin edge 51 on the frame 6 at a preset angle.

[0079] Optionally, the angle of the first first side stamping die set 31 is 45°, the angle of the second first side stamping die set 31 is 90°, and the angle of the third first side stamping die set 31 is 135°.

[0080] The first first side punching driving member 314 is installed at an angle of 45° downward along the horizontal direction. In this embodiment, when the frame 6 and the skin 5 are moved to the installation position, the plane where the frame 6 is located is located on the horizontal plane. During punching, the first first side punching head 313 is driven by the first first side punching driving member 314 to punch the skin 5 at an angle of 45° downward from the position of 45° upward of the skin 5. The first first punching end face 311 of the first first side punching head 313 is punched on the skin edge 51, so that the skin edge 51 is bent 45°.

[0081] The second first side punching driving member 314 is installed in the horizontal direction (in this embodiment, when the frame 6 and the skin 5 are moved to the installation position, the plane where the frame 6 is located is located on the horizontal plane). During punching, the second first side punching head 313 is driven by the second first side punching driving member 314 to punch the skin 5 in the horizontal direction from a position on one side of the skin 5 in the horizontal direction. The second first punching end face 311 of the second first side punching head 313 punches the skin edge 51 which has been formed at 45 degrees, so that the skin edge 51 is bent by 90 degrees.

[0082] The third first side stamping driving member 314 is installed in the horizontal direction (in this embodiment, when the frame 6 and the skin 5 are moved to the installation position, the plane where the frame 6 is located is on the horizontal plane). During stamping, the third first side stamping head 313 is driven by the third first side stamping driving member 314 to stamp the skin 5 in the horizontal direction from a position on one side of the horizontal direction of the skin 5. The second first stamping end face 311 of the second first side stamping head 313 is stamped on the skin edge 51 that has formed a 90° angle, so that the skin edge 51 is bent 135°.

[0083] It needs to be further explained that the first first edge stamping drive member 314 is installed obliquely downward in the horizontal direction instead of being arranged horizontally. The reason is that during the first stamping, the skin edge 51 is not bent. If the skin edge 51 is stamped directly in the horizontal direction, it is easy for the skin edge 51 to warp up, reducing the effect of the edging.

[0084] By adopting the above technical solution, the skin 5 is bent by stamping, thereby improving the efficiency of the hemming.

[0085] Please refer again Fig. 9 In one embodiment, the second side stamping die set 41 includes a second side stamping connecting plate 412, a second side stamping head 413 and a second side stamping driving member 414, the second stamping end face 411 is formed on the second side stamping head 413, the second side stamping head 413 is slidingly connected to the second side stamping connecting plate 412, and the second side stamping driving member 414 drives the second side stamping head 413 to press against the second side 62 of the frame 6.

[0086] Specifically, the second side stamping head 413 is driven by the second side stamping driving member 414 to move toward the second side 62 of the frame 6 until the second stamping end face 411 is pressed against the second side 62 of the frame 6. Since the second stamping end face 411 forms a preset angle with the plane where the frame 6 is located, the second stamping end face 411 bends the skin edge 51 on the frame 6 at a preset angle.

[0087] By adopting the above technical solution, the skin 5 is bent by stamping, thereby improving the efficiency of the hemming.

[0088] Please refer again Figure 8 In one embodiment, the first side clamping module 32 includes a first side clamping plate 321, a second side clamping plate 322 and a first side clamping driving member 323, the first side clamping plate 321 is rotatably connected to the first side clamping plate 321, the first clamping portion of the first side clamping plate 321 and the second clamping portion of the second side clamping plate 322 form a clamping structure, and the first side clamping driving member 323 is connected to the first side clamping plate 321 and the second side clamping plate 322 to adjust the opening angle of the clamping structure.
