Description

Technical Field

[0001] This application relates to the field of metal plate cutting, and particularly to a variable-spacing placement table for metal plate cutting. Background Art

[0002] Metal plates refer to thin and flat plate-like components made of metal materials. Common metal materials include steel, aluminum, stainless steel, etc. Metal plates usually have relatively high strength and hardness. During the processing, it is necessary to cut and trim the metal plates according to the design requirements to process them into different shapes and structures.

[0003] Metal plates are usually placed on the cutting table during cutting. However, some metal plates have a certain overall length, and the overall placement length of the cutting table is limited. When the metal plate is relatively long, the two sides of the metal plate placed on the cutting table will naturally droop, and then the middle position of the metal plate will bend and warp. The bent metal plate has a certain impact on its overall cutting and processing, reducing the overall placement effect of the metal plate on the cutting table.

[0004] Regarding the above related technologies, the inventor believes that there is a defect of insufficient placement space when the metal plate is cut and placed. Therefore, a variable-spacing placement table for metal plate cutting is proposed to solve the above problems. Utility Model Content

[0005] In order to solve the problem of insufficient placement space when the metal plate is cut and placed, this application provides a variable-spacing placement table for metal plate cutting.

[0006] The variable-spacing placement table for metal plate cutting provided by this application adopts the following technical solutions:

[0007] A variable-spacing placement table for metal plate cutting includes a cutting placement table. Fixed support rods are symmetrically welded to the tops of both sides of the cutting placement table. A fixing plate is welded to one side of the two fixed support rods on the same side. A number of first support platforms are movably installed on the outer surface of the fixed support rods. A second support platform is movably installed on the outer surface of the fixed support rods near the fixing plate. Fixed seats are fixedly connected to the tops of both sides of the cutting placement table. A first connecting rod is hinged to the bottom end of the fixed seat. A second connecting rod is rotatably installed in the middle of the bottom end of the first support platform. A third connecting rod is hinged between the bottom edges of adjacent second connecting rods. A fourth connecting rod is rotatably installed in the middle of the bottom end of the second support platform. The edges of the first connecting rod and the fourth connecting rod are rotatably connected to the edges of the second connecting rod. A connecting plate is fixedly installed at the bottom of one side of the second support platform. A rotating mechanism is further provided below the first support platform and the second support platform for adjusting the activities of the first support platform and the second support platform.

[0008] Preferably, the rotating mechanism includes a bidirectional lead screw, which passes through the cutting placement table and is rotatably installed at the bottom between two fixed plates. A fixed inner cavity is provided inside the cutting placement table. A driven gear is rotatably installed in the middle on one side of the outer surface of the bidirectional lead screw. A servo motor is installed in the middle at the bottom end of the fixed inner cavity, and a driving gear is installed at the output end on one side of the servo motor.

[0009] Preferably, through holes are symmetrically opened through the side edges of the first support table and the second support table. The outer diameter of the fixed support rod is smaller than the inner diameter of the through hole. One side of the outer surface of the fixed support rod is located inside the through hole, and both the first support table and the second support table are fitted with the fixed support rod.

[0010] Preferably, external threads with opposite thread patterns are respectively provided on both sides of the outer surface of the bidirectional lead screw. A threaded hole is opened through the bottom of one side of the connecting plate. One side of the outer surface of the bidirectional lead screw is located inside the threaded hole, and the bidirectional lead screw and the threaded hole are adapted to each other.

[0011] Preferably, the driving gear is directly below the driven gear, the top of the outer surface of the driving gear is close to the bottom of the outer surface of the driven gear, and the driven gear and the driving gear are meshed with each other.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] By placing the metal plate on the upper surface of the cutting placement table, the driving gear rotates to drive the driven gear and the bidirectional lead screw to rotate, thereby adjusting the distance between the two second support tables. The moving second support table drives the fourth connecting rod, the second connecting rod, the third connecting rod and the first connecting rod to rotate synchronously, thereby pulling multiple first support tables to move, and adjusting the first support table and the second support table to move on the outer surface of the fixed support rod to the lower surface of the metal plate. Compared with the prior art, this solution has the effect of facilitating the placement of metal plates of different sizes, improving the support effect of the first support table and the second support table on the metal plate, solving the problem of bending during placement due to the long sides of the metal plate, and improving the overall cutting efficiency of the metal plate.

[0018] The following will Figures 1-3 further elaborate on this application in detail.

[0019] The embodiment of this application discloses a variable-spacing placement table for metal plate cutting. Refer to Figures 1-3 , a variable-spacing placement table for metal plate cutting, including a cutting placement table 1. Fixed support rods 2 are symmetrically welded to the tops of both sides of the cutting placement table 1. Fixed plates 3 are welded to one side of the two fixed support rods 2 on the same side. A number of first support tables 4 are movably installed on the outer surface of the fixed support rods 2. Second support tables 5 are movably installed on the outer surface of the fixed support rods 2 near the fixed plates 3. Through holes are symmetrically and penetratingly opened at the side edges of one side of the first support tables 4 and the second support tables 5. The outer diameter of the fixed support rods 2 is smaller than the inner diameter of the through holes. One side of the outer surface of the fixed support rods 2 is located inside the through holes. Both the first support tables 4 and the second support tables 5 are mutually fitted with the fixed support rods 2. Fixed seats 6 are fixedly connected to the tops of both sides of the cutting placement table 1. The bottom ends of the fixed seats 6 are hinged with first connecting rods 7. The middle parts of the bottom ends of the first support tables 4 are rotatably installed with second connecting rods 8. Third connecting rods 9 are hinged between the bottom edges of adjacent two second connecting rods 8. The middle parts of the bottom ends of the second support tables 5 are rotatably installed with fourth connecting rods 10. The edges of the first connecting rods 7 and the fourth connecting rods 10 are rotatably connected to the edges of the second connecting rods 8. A connecting plate 11 is fixedly installed at the bottom of one side of the second support tables 5. A rotating mechanism is also provided below the first support tables 4 and the second support tables 5 for adjusting the activities of the first support tables 4 and the second support tables 5.

[0020] By placing the metal plate on the upper surface of the cutting placement table 1, the movement of the second support table 5 drives the fourth connecting rod 10 to rotate, the fourth connecting rod 10 drives the second connecting rod 8 to move synchronously, the second connecting rod 8 drives the other multiple second connecting rods 8 to rotate synchronously under the connection of the third connecting rod 9, and at the same time the second connecting rod 8 drives the first connecting rod 7 to rotate synchronously. Furthermore, the moving second support table 5 pulls multiple first support tables 4 to move, adjusts the spacing between the multiple first support tables 4 on the outer surface of the fixed support rods 2, and adjusts the activities of the first support tables 4 and the second support tables 5 on the outer surface of the fixed support rods 2 to be placed under the lower surface of the metal plate, reflecting the supporting effect of the first support tables 4 and the second support tables 5 on metal plates of different sizes and lengths.

[0021] Refer to Figure 2 and Figure 3, the rotating mechanism includes a bidirectional lead screw 12. The bidirectional lead screw 12 passes through the cutting placement table 1 and is rotatably installed at the bottom between two fixed plates 3. Threads with opposite thread patterns are respectively provided on both sides of the outer surface of the bidirectional lead screw 12. A threaded hole is penetrated and opened at the bottom of one side of the connecting plate 11. One side of the outer surface of the bidirectional lead screw 12 is located inside the threaded hole, and the bidirectional lead screw 12 and the threaded hole are mutually adapted. A fixed inner cavity 13 is opened inside the cutting placement table 1. A driven gear 14 is rotatably installed in the middle of one side of the outer surface of the bidirectional lead screw 12. A servo motor 15 is installed in the middle of the bottom end of the fixed inner cavity 13. A driving gear 16 is installed at the output end of one side of the servo motor 15. The driving gear 16 is located directly below the driven gear 14. The top of the outer surface of the driving gear 16 is close to the bottom of the outer surface of the driven gear 14, and the driven gear 14 and the driving gear 16 are meshed with each other.

[0022] By starting the servo motor 15 to drive the driving gear 16 to rotate, the driving gear 16 rotates to drive the driven gear 14 and the bidirectional lead screw 12 to rotate, so that the rotating bidirectional lead screw 12 drives the connecting plate 11 to move relatively or towards each other, and further enables the two second support platforms 5 to move along the outer surface of the fixed support rod 2 to adjust the distance, reflecting the adjustment effect of the bidirectional lead screw 12 on the distance between the two second support platforms 5.

[0023] The implementation principle of a variable-distance placement table for metal plate cutting in the embodiment of the present application is as follows: By placing the metal plate on the upper surface of the cutting placement table 1, starting the servo motor 15 to drive the driving gear 16 to rotate, the input end of the power supply of the servo motor 15 is electrically connected to the output end of an external power supply, the driving gear 16 rotates to drive the driven gear 14 and the bidirectional lead screw 12 to rotate, so that the rotating bidirectional lead screw 12 drives the connecting plate 11 to move relatively or towards each other, and further enables the two second support platforms 5 to move along the outer surface of the fixed support rod 2 to adjust the distance, enabling the moving second support platform 5 to drive the fourth connecting rod 10 to rotate, the fourth connecting rod 10 drives the second connecting rod 8 to move synchronously, the second connecting rod 8 drives the remaining multiple second connecting rods 8 to rotate synchronously under the connection of the third connecting rod 9, and at the same time the second connecting rod 8 drives the first connecting rod 7 to rotate synchronously, and further enables the moving second support platform 5 to pull the multiple first support platforms 4 to move, adjusting the distance between the multiple first support platforms 4 on the outer surface of the fixed support rod 2, and adjusting the first support platform 4 and the second support platform 5 to move on the outer surface of the fixed support rod 2 to be placed under the lower surface of the metal plate; compared with the prior art, this solution has the effect of facilitating the placement of metal plates of different sizes, improving the support effect of the first support platform 4 and the second support platform 5 on the metal plate, solving the problem of bending during placement due to the longer sides of the metal plate, and improving the overall cutting efficiency of the metal plate.
