The working principle of this equipment is: feed the metal plate 5 (generally steel plate) from the feed port 11, under the action of the driving device 4, the plate feeding rolling device 2 sends the metal plate 5 into the continuous axial pressing device 3, At the same time, the plate feeding rolling device 2 compresses the metal plate 5, and the continuous axial pressing device 3 presses and forms the metal plate 5; when the forming distance or angle adjustment of the metal plate 5 needs to be changed, the continuous axial pressing The device 3 can be adjusted, which not only facilitates the adjustment of the angle and size of the folding forming, but also the metal plate 5 can be formed after passing through the continuous axial pressing device 3, and the efficiency is high. , can also be formed in one pass, the forming range is large, and it is not limited by the length and size of the metal plate 5;

In this equipment, the driving device 4 includes a motor 41 and a chain 42, the output shaft of the motor 41 is connected with a main sprocket, and the main sprocket is connected with the plate feeding roller pressing device 2 and the continuous axial pressing device through the chain 42 3 transmission connection, the chain 42 has transmission redundancy, especially for synchronous transmission, the transmission redundancy is conducive to the coordination between related agencies, and at the same time, the motor 41 is preferably hydraulic, so that the hydraulic motor 41 has the advantages of impact resistance and small inertia, and is especially suitable for slow bending and forming of this equipment.

In the technical solution, the plate feeding rolling device 2 at least includes a first conveying roller set 21, and the first conveying roller set 21 includes an upper roller 211 and a lower roller 212 that is in clearance with the upper roller 211, and the upper roller 211 or the lower roller 212 is provided with a first sprocket for transmission connection with the driving device 4 . At the same time, the upper roller 211 and the lower roller 212 are driven by gears, so as to realize synchronization up and down. When the thickness of the metal plate 5 is 2mm, when forming, the metal plate 5 passes between the upper roller 211 and the lower roller 212, and the upper roller 211 and the lower roller 212 tightly press the metal plate 5 , and under the rotation of the upper roller 211 and the lower roller 212 , the metal plate 5 moves forward into the continuous axial pressing device 3 .

Since the metal plate 5 is formed immediately after entering the continuous axial pressing device 3, the transverse shear force during forming will inevitably affect the plate feeding rolling device 2. In order to further make the gap between the upper roller 211 and the lower roller 212 have a certain expansion and contraction , the surface of the upper roller 211 or/and the surface of the lower roller 212 is provided with a lining layer. In this way, under the action of the rubber lining layer, the gap between the upper roller 211 and the lower roller 212 can be changed under the transverse shear force of the molding. It is known from experiments that the thickness of the rubber lining layer is set between 0.5~3mm , in this embodiment, when the thickness of the metal plate 5 is 2mm, it is preferably 0.5mm, so that the gap between the upper roller 211 and the lower roller 212 is less than 0.5mm, which is beneficial to ensure the accuracy of forming.

When the metal plate 5 has three bending and forming positions 51 (such as shown in Figure 16), in this technical solution, the continuous axial pressing device 3 includes a middle axial pressing mechanism 31 and an edge axial pressing mechanism 32 arranged in sequence, Both the central axial pressure mechanism 31 and the side axial pressure mechanism 32 are fixedly connected to the machine base 1 . When forming, the middle forming position 51 of the metal plate 5 is formed by using the central axial pressing mechanism 31 first, and then the edge of the metal plate 5 is formed by using the edge axial pressing mechanism 32 after the intermediate forming position 51 is completed.

In this technical solution, the central axial pressure mechanism 31 at least includes a first axial pressure group 311 , a second axial pressure group 312 and a third axial pressure group 313 arranged in sequence; the first axial pressure group 311 includes a first The driving shaft 3111 and the first driven shaft 3112 which is in clearance fit with the first driving shaft 3111, the first driving shaft 3111 is provided with a first folding tool 3113, and the first driven shaft 3112 is provided with a second folding tool The cutter 3114, the first folding cutter 3113 and the second folding cutter 3114 are in clearance fit, and the first driving shaft 3111 is provided with a second sprocket for transmission connection with the driving device 4 . The first driving shaft 3111 and the first driven shaft 3112 adopt gear transmission, so as to realize synchronization up and down. When forming, the metal plate 5 passes between the first driving shaft 3111 and the first driven shaft 3112, and the first folding The tool 3113 and the second bending tool 3114 bend the middle part of the metal plate 5. The structure of the second axial pressure group 312 and the third axial pressure group 313 is roughly the same as that of the first axial pressure group 311. The difference is In that: the bending angles of the first bending tool 3113 and the second bending tool 3114 to the metal plate 5 are different, for example: the first axial pressure group 311 uses a tool to bend the middle part of the metal plate 5 by 7°, and the second axial pressure The group 312 continues to bend the middle part of the metal plate 5 to 17° with a tool, and the third axial pressure group 313 uses a tool to continue to bend the middle part of the metal plate 5 to 27°, so as to achieve the desired shape of the middle part of the metal plate 5 .

When the first folding tool 3113 and the second folding tool 3114 bend the metal plate 5, the metal plate 5 will shrink between the first driving shaft 3111 and the first driven shaft 3112, in order to make the metal plate 5 The bending forming is smoother. When the metal plate 5 enters the first driving shaft 3111 and the first driven shaft 3112, there is a contraction gap between the metal plate 5 and the first driving shaft 3111 and the first driven shaft 3112, so that Shrink molding of the metal plate 5 is smoother.

Press group 315. Continuing according to the above example, the fourth axial pressure group 314 continues to use the cutter to continue bending the middle part of the metal plate 5 to 37°, and the fifth axial pressure group 315 continues to use the cutter to continue to bend the middle part of the metal plate 5 to 47°, thereby Through the above-mentioned five consecutive axial pressings, the middle part of the metal plate 5 reaches the desired shape.

Then, in this technical solution, the side axial pressure mechanism 32 includes a sixth axial pressure group 321 , a seventh axial pressure group 322 and an eighth axial pressure group 323 arranged in sequence, and the sixth axial pressure group 321 includes The second driving shaft 3211 and the second driven shaft 3212 clearance fit with the second driving shaft 3211, the second driving shaft 3211 is provided with a third folding tool 3213, and the second driven shaft 3212 is provided with a fourth The folding tool 3214, the third folding tool 3213 and the fourth folding tool 3214 are in clearance fit, and the second driving shaft 3211 is provided with a third sprocket for transmission connection with the driving device 4 . The second driving shaft 3211 and the second driven shaft 3212 are also geared to achieve synchronization up and down. The third folding tool 3213 and the fourth folding tool 3214 are provided with two sets, respectively located on both sides , the position can be adjusted according to the needs of its forming. When the middle part of the metal plate 5 is formed, the metal plate 5 enters the sixth shaft pressing group 321, and under the action of the second driving shaft 3211 and the second driven shaft 3212, The third folding cutter 3213 and the fourth folding cutter 3214 bend the two sides of the metal plate 5. Obviously, the structure of the seventh axial pressure group 322 and the eighth axial pressure group 323 is the same as that of the sixth axial pressure group 321. Roughly the same, the difference is that the bending angles of the third folding tool 3213 and the fourth folding tool 3214 to the metal plate 5 are different, for example: the sixth axis pressing group 321 uses the tool to bend the two sides of the metal plate 5 Bending 7°, the seventh axial pressure group 322 continues to bend the middle of the metal plate 5 to 17° with a tool, and the eighth axial pressure group 323 continues to bend the middle of the metal plate 5 to 27° with a tool, so as to reach the The shape that needs to be formed in the middle of the plate 5.

Similarly, when a larger angle is required in the partial forming shape, such as 47°, the edge axial pressure mechanism 32 further includes a ninth axial pressure group 324 and a tenth axial pressure group 325 arranged in sequence. Continuing with the above example, the ninth axial pressure group 324 continues to use the cutter to continue bending the edge of the metal plate 5 to 37°, and the tenth axial pressure group 325 continues to use the cutter to continue to bend the edge of the metal plate 5 to 47° , so that through the above-mentioned five consecutive axial pressures, the edge of the metal plate 5 can reach the shape that needs to be formed, and finally complete the predetermined forming requirements. Under the combination of the above disclosed schemes and examples, the technology in this field can be flexibly used to carry out bending at angles of 20°, 30°, 40°, etc., which can be realized by installing corresponding tools according to the needs of the angle value, and this scheme is not an example lift.
