Description

Technical Field

[0001] This invention relates to the field of online sawing of sheet metal, specifically to an online step-by-step sawing device for sheet metal. Background Technology

[0002] In recent years, with the increasing development of automation technology in sheet metal sawing, automatic loading, unloading, positioning, and cutting of sheets have become possible, resulting in significant improvements in sawing efficiency and precision compared to traditional sheet metal sawing equipment. However, in actual production processes, current automated sawing equipment still faces some technical shortcomings or bottlenecks:

[0003] (1) When conveying sheet metal by rollers, the conveying speed and stability of the sheet metal may be affected by factors such as the diameter, material, and friction of the rollers. If the spacing between the rollers is uneven or the friction of the rollers is inconsistent, the sheet metal may shake or jump during the conveying or sawing process, which will seriously affect production efficiency and product quality and is not conducive to the production stability of the product. Therefore, some sawing devices use chain plate conveying devices to replace the existing roller conveying devices to improve the transport stability, but this also leads to higher equipment costs and increases the investment and operating costs of enterprises. In addition, during the conveying of sheet metal by chain plate, since the sheet metal is placed directly on the chain plate, it may be affected by the movement of the chain plate during adjustment, making it difficult to achieve high-precision adjustment requirements. Moreover, during the adjustment process, the sheet metal may rub or collide with the chain plate, causing surface damage.

[0004] (2) Limited adaptability: Existing automated sawing devices are generally designed for specific board sizes and shapes, and may need to be adjusted and modified for different types and specifications of boards. In particular, the adjustment of the sawing device is generally synchronized with the movement of the track. Since the track requires a certain amount of running space, the position adjustment of the sawing device is very limited, which in turn limits the sawing size of the board and results in poor adaptability.

[0005] (3) Limited sawing accuracy: Traditional board sawing is mostly done by sawing the same board at the same time. Therefore, the internal stress of the board will be released at the same time during sawing. This process can easily lead to board deformation and affect sawing accuracy.

[0006] Therefore, although automated sawing technology can improve the efficiency and accuracy of board sawing, it still has some technical defects and challenges. Summary of the Invention

[0007] To address the technical deficiencies of existing technologies, this invention proposes an online step-by-step sawing device for sheet metal. This device not only improves the sawing accuracy and transmission stability of sheet metal, but also further enhances the sawing stability and ensures the straightness of the sawing by performing step-by-step sawing from the outside to the inside of the sheet metal.

[0030] (4) In this invention, by using the chain plate conveying device and the support roller mechanism in combination with the independently adjustable sawing device, the spatial interference between the devices can be effectively reduced. There is no limitation on the position adjustment of the sawing device. It can be used not only for the long side cutting of the board, but also for the short side cutting of the board, which further improves the adaptability of the board sawing. It is suitable for cutting boards of various sizes, with a wider range of applications and more flexible adjustment. Attached Figure Description

[0067] Each set of adjusting support devices 10 includes two adjusting supports 10-1, symmetrically arranged on the outside of the auxiliary conveying device 5 of the adjusting section, for adjusting the position of the plate. In this embodiment 1, the plate contact end of the adjusting support 10-1 is provided with several rolling wheels 10-2, and the several rolling wheels 10-2 are coaxially arranged along the vertical axis to reduce contact friction with the plate.

[0068] In this invention, the specific structure and working method of the adjusting backrest device 10 are all conventional technical means, so they are not described in detail. Those skilled in the art can selectively design the adjusting backrest according to actual needs.

[0069] Combination Figure 3 , Figure 6 and Figure 7 The specific structure of the adjusting roller mechanism 11 is described below.

The connecting end of at least one adjusting roller assembly 11-1 is connected to the connecting rod 11-2, and the adjusting roller assemblies 11-1 are arranged along the connecting rod 11-2. The adjusting roller assembly 11-1 is rotatably connected to the frame 4, and the adjusting roller assembly 11-1 rotates and rises around its rotational connection point under the drive of the connecting rod 11-2. Figure 6 As shown, the driving end of the linkage drive device 11-3 moves upward in the inclined or vertical direction, thereby driving the linkage 11-2 to move upward.

[0070] In this embodiment 1, the adjusting roller assembly 11-1 includes an adjusting roller 11-11, a connecting plate I 11-12, and a connecting plate II 11-13. The two ends of the roller shaft of the adjusting roller 11-11 are rotatably connected to the connecting plate I 11-12 and the connecting plate II 11-13, respectively. The connecting plate I 11-12 is located on the side close to the chain conveyor 3. The connecting plate I 11-12 and the connecting plate II 11-13 are rotatably connected to the frame 4 and the chain frame 3-1, respectively. The connecting plate I 11-12 extends downward and is provided with a connecting arm for connecting the connecting rod 11-2.

[0071] In this embodiment 1, each adjusting roller assembly 11-1 is positioned between two adjacent sets of support roller assemblies I. To further save installation space, the connecting plate I 11-12 and connecting plate II 11-13 of the adjusting roller assembly are rotatably mounted on the two sets of support roller frames I 5-12 of the support roller assembly I. Initially, the plate conveying surface of the adjusting roller assembly 11-1 is lower than the plate conveying surface of the support roller assembly I. When adjusting the position, the plate conveying surface of the adjusting roller assembly 11-1 is higher than the plate conveying surface of the support roller assembly I, and the plate conveying surface of the support roller assembly I and the plate conveying surface of the chain conveyor 3 are always on the same plane.

[0072] In this embodiment 1, the adjusting roller assemblies 11-1 in the two sets of adjusting roller mechanisms 11 are arranged in a one-to-one correspondence, and the central axes of two adjacent adjusting rollers in the X-axis direction of the frame coincide.

[0073] Combination Figure 8 The specific structure of the sawing device 9 is described below. Each sawing device 9 includes two sawing mechanisms 9-1, two mounting plates 9-2, at least one guide rod assembly 9-3, two lead screws 9-4, and two sawing drive motors 9-5. The two mounting plates 9-2 are symmetrically installed on both sides of the overall frame 4 for mounting the guide rod assembly 9-3, lead screws 9-4, and sawing drive motors 9-5. Each guide rod assembly 9-3 includes two guide rods 9-31, which are installed on both sides of the chain conveyor 3, with their central axes coinciding. The two guide rods 9-31 are connected by a coupling. 9-32 connection; two lead screws 9-31 are respectively set on both sides of the chain plate conveying device 3, and the central axes of the two lead screws 9-31 coincide; two sawing drive motors 9-5 are respectively mounted on two mounting support plates 9-2, and the output end of the sawing drive motor 9-5 is driven and connected to the lead screw 9-4; two sets of sawing mechanisms 9-1 are respectively set on both sides of the chain plate conveying device 3, and each set of sawing mechanisms 9-1 is connected to the guide rod 9-31 and lead screw 9-4 located on the same side. The sawing mechanism 9-1 moves along the guide rod 9-31 to adjust its position distribution under the drive of the lead screw 9-4.

[0074] In this embodiment 1, as Figure 9-12 As shown, the sawing mechanism 9-1 includes a movable connecting frame 9-11, a rotating connecting plate 9-12, an adjusting plate 9-13, and a sawing assembly 9-14. The movable connecting frame 9-11 is mounted on a guide rod 9-31 and a lead screw 9-4 on the same side. The lead screw 9-4 drives the movable connecting frame 9-11 to move along the guide rod 9-31. One side of the adjusting plate 9-13 has a protrusion 9-15 along the Z-axis, and the upper end of the other side has a circular groove 9-16. The adjusting plate 9-13 is movably mounted on the movable connecting frame 9-11. The side of the 11 is provided with a circular protrusion 9-18 at the bottom of one side of the rotating connecting plate 9-12, which is used to cooperate with the circular groove 9-16 on the adjusting plate 9-13. The rotating connecting plate 9-12 is connected to one side of the adjusting plate 9-13. The sawing assembly 9-14 is installed on the rotating connecting plate 9-12 and rotates and adjusts around the Y-axis in the circular groove 9-16 with the rotating connecting plate 9-12.

[0075] In this embodiment 1, the bottom of the adjusting plate 9-13 is connected to the movable connecting frame 9-11 by adjusting bolts, so as to realize the up and down adjustment of the adjusting plate 9-13 in the Z-axis direction.

[0076] In this embodiment 1, in order to further improve the stability of the sawing mechanism movement, the guide rod assembly 9-3 is preferably in two sets.

[0077] In this embodiment 1, each set of sawing devices 9 is arranged between adjacent roller assemblies II. To further save installation space, the support roller frame II of the support roller assembly II can be installed on the two mounting plates of the sawing device respectively.

[0078] In this invention, any existing rotary cutting sawing assembly can be installed on the rotary connecting plate 9-12 of the sawing mechanism 9-1 to achieve sheet metal sawing. Those skilled in the art can also select sawing assemblies with built-in dust removal functions according to actual needs.

[0079] To further improve the stability of the plate material transmission, in this embodiment 1, at least one set of clamping devices 7 is provided on the beam frame 13 set in the Y-axis direction of the frame, and each set of clamping devices 7 uses double rows of pressure rollers to contact the plate material surface to achieve clamping transmission.

[0080] To provide more accurate position adjustment information, at least two sets of vision devices 8 are installed on the beam frame 13 of the position adjustment section 1. The line connecting the at least two sets of vision devices 8 is parallel to the position of the sawing mark line on the board, which is used to collect the position of the sawing mark line on the board in real time online.

[0081] like Figure 14As shown, in order to further improve the working environment of the board sawing, a dust removal device 12 that can move along the X-axis of the frame can be installed on the beam frame 13 of the board sawing section 2, and is located directly above the sawing components 9-14, corresponding to the sawing components 9-14, to remove the debris located outside the sawing components during sawing.

[0082] In this invention, the beam frame 13 can also be configured as a liftable beam frame structure, thereby adjusting the height of the dust removal device 12 and the pressing device 7 as a whole; or the liftable pressing device 7 and the liftable dust removal device 12 can be set independently. Existing lifting devices are all applicable and are conventional technical means for those skilled in the art, so they are not described in detail.

[0083] The working principle of this invention is as follows:

[0084] During the entire sawing process, the board is adjusted in position by the position adjustment section 1 and then transported to the board sawing section 2 for sawing. The specific position adjustment method of the board in the position adjustment section 1 is as follows:

[0085] Driven by the chain conveyor 3, the sheet metal moves along the Y-axis of the frame to the sheet metal sawing section 2. At the same time, the support roller mechanism I5-1 in the adjustment section auxiliary conveyor 5 provides support and guidance for the sheet metal transmission. When the sheet metal is in the position adjustment section 1, the connecting rod drive device 11-3 drives the connecting rod 11-2 to lift upward, thereby driving the adjustment roller assembly 11-1 connected to the connecting rod 11-2 to rotate upward around the rotation connection point (rotatably connected to the frame), so that the sheet metal leaves the chain conveyor 3.

[0086] Subsequently, the vision devices 8 are controlled to operate. Based on the principle that two points determine a straight line, the two vision devices 8 capture the positional relationship of the sawing marks on the board by taking pictures, and feed the captured image information back to the control system for data processing. When the control system analyzes the captured data and determines the offset distance between the sawing marks and the position baseline, it controls the adjusting device 10 to correct the position of the board. In this invention, the process of obtaining offset position information (or position adjustment information) by processing the sawing marks captured by the vision devices is a conventional technique and therefore not described in detail.

[0087] After the position correction is completed, the control linkage drive device 11-3 drives the linkage 11-2 to descend, thereby driving the adjusting roller assembly 11-1 to return to the initial position. At this time, the plate is back on the chain plate conveyor device 3, and the chain plate conveyor device 3 drives the plate to continue moving forward to the plate sawing section 2.

[0088] The specific sawing method for the board in sawing section 2 is as follows:

[0089] First, the position distribution of the sawing devices 9 is adjusted according to the sawing scheme.
