Description

Technical Field

[0001] This application relates to the field of sheet metal cutting, and in particular to a sheet metal cutting and clamping assembly. Background Technology

[0002] Board cutting refers to the process of cutting large-sized boards into smaller-sized boards or specific shapes that meet design requirements in industries such as wood processing, furniture manufacturing, and building decoration. Cutting is the first step in board processing. When cutting boards, clamping components are usually set on the cutting table to fix the boards in place.

[0003] The clamping assembly generally consists of a hydraulic telescopic rod and a rotating clamping roller. After the sheet is placed on the worktable, the hydraulic telescopic rod drives the clamping roller to clamp the sheet. Then the cutting blade cuts the sheet. As the cutting blade moves, the clamping roller rolls on the sheet following the cutting blade.

[0004] However, in actual operation, the existing clamping components only use clamping rollers to press and resist the surface of the board, ignoring the edge of the board. When cutting the board, the board may still shift towards the edge, resulting in cutting errors. Utility Model Content

[0005] The purpose of this application is to address the problem in the background art that only the pressing roller is used to press and resist the surface of the board, ignoring the edge of the board. When cutting the board, the board may still deviate towards the edge, resulting in cutting errors. This application provides a board cutting and pressing assembly.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A sheet metal cutting and clamping assembly includes a cutting table with two symmetrical movable support seats slidably connected to it. A movable support frame is fixed between the two movable support seats. A cutting head is slidably connected to the movable support frame, and a cutting knife is installed on the cutting head. Support rods are fixed on both movable support seats. Two symmetrical downward pressure rollers are arranged between the two support rods. Hydraulic telescopic rods are provided at both ends of the downward pressure rollers. The telescopic ends of the hydraulic telescopic rods are rotatably connected to the downward pressure rollers. The hydraulic telescopic rods are fixedly connected to the support rods. A clamping and stabilizing mechanism is provided on the downward pressure rollers. The clamping and stabilizing mechanism includes two U-shaped adjusting frames symmetrically arranged on the downward pressure rollers. Clamping wheels are rotatably connected to both ends of the adjusting frames.

[0008] By adopting the above technical solution, the hydraulic telescopic rod drives the lower pressure roller to abut against the plate, while the two adjusting frames of the clamping and stabilizing mechanism drive the clamping wheels to abut against the edge of the plate. This can further improve the stability of the plate during cutting and further reduce the possibility of the plate shifting when placed on the cutting table.

[0009] Furthermore, a clamping frame is fixed between the two support rods, an adjustment component is provided between the clamping frame and the two adjustment frames, a connecting component is provided on the two adjustment frames, and a following component is provided between the adjustment frame and the lower pressure roller.

[0010] By adopting the above technical solution, the adjustment component drives the connecting component, which in turn drives the two adjustment frames to move on the clamping frame. The following component allows the adjustment frame and the lower pressure roller to move simultaneously, thus making it easy for the clamping wheel on the adjustment frame to contact the edge of the plate, and also easy to contact plates of different widths.

[0011] Furthermore, the connecting assembly includes a second connecting rod fixed on the adjusting frame, and a first connecting rod is slidably connected to the second connecting rod.

[0012] By adopting the above technical solution, the second connecting rod is fixedly connected to the adjustment frame, and then the second connecting rod slides in the first connecting rod, thereby making it easy to adjust the height of the adjustment frame.

[0013] Furthermore, the first connecting rod has a limiting groove that extends through it, and the second connecting rod has a limiting block fixed at one end near the first connecting rod. The limiting block is located in the limiting groove and is slidably connected to the first connecting rod.

[0014] By adopting the above technical solution, the second connecting rod drives the limiting block to slide on the first connecting rod, thereby reducing the possibility of the first connecting rod and the second connecting rod separating.

[0015] Furthermore, the adjustment assembly includes two sliding blocks symmetrically arranged on the clamping frame. The clamping frame has a sliding groove, and the two sliding blocks are located in the sliding groove and are fixedly connected to the corresponding connecting rod.

[0016] By adopting the above technical solution, the two sliding blocks move in the sliding groove, which makes it easy for the sliding blocks to drive the connecting rod to move.

[0017] Furthermore, a bidirectional threaded rod is rotatably connected to the clamping frame. The bidirectional threaded rod is located in the sliding groove, passes through two sliding blocks, and is threadedly connected to the two sliding blocks. A drive motor is fixed on the clamping frame, and the output end of the drive motor passes through the clamping frame and is fixedly connected to the bidirectional threaded rod.

[0018] By adopting the above technical solution, when the bidirectional threaded rod rotates, it drives the two sliding blocks to move simultaneously, which makes it easy to clamp the plate in the middle with the clamping wheel and reduce the possibility of plate displacement.

[0019] Furthermore, the following assembly includes a connecting block fixed to one side of the adjusting frame, a following ring fixed on the connecting block, and the following ring sleeved on the lower pressure roller.

[0020] By adopting the above technical solution, the lower pressure roller drives the following ring when it moves, and the following ring drives the adjusting frame through the connecting block, so that the adjusting frame can move simultaneously with the lower pressure roller, and the clamping wheel can be adjusted when the lower pressure roller is in contact with plates of different thicknesses.

[0021] Furthermore, the inner wall of the following ring is rotatably connected with several abutting balls, which abut against the lower pressure roller.

[0022] By adopting the above technical solution, when the lower pressure roller rolls on the plate, the abutting ball connected to the inner wall of the following ring rotates between the abutting ring and the lower pressure roller, thereby reducing the friction between the lower pressure roller and the following ring.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, when the lower roller abuts against the sheet metal, the clamping wheel on the adjusting frame is positioned at the edge of the sheet metal. The drive motor drives the bidirectional threaded rod, which in turn drives two sliding blocks. The two sliding blocks move simultaneously in the sliding grooves on the clamping frame. The sliding blocks drive connecting rod one, which in turn drives connecting rod two, which in turn drives the adjusting frame. The adjusting frame then drives the clamping wheel to abut against the edge of the sheet metal. By using the clamping wheel to clamp the edge of the sheet metal, the stability of the sheet metal during cutting is further improved, and the possibility of the sheet metal shifting when placed on the cutting table is further reduced.

[0025] 2. In this application, when the hydraulic telescopic rod drives the support rod to press down onto the plate, the lower pressure roller drives the following ring, the following ring drives the connecting block, and the connecting block drives the adjusting frame, allowing the adjusting frame to drive the connecting rod two to slide in the connecting rod one. This allows the clamping wheel on the adjusting frame to move synchronously with the lower pressure roller. When the lower pressure roller abuts against the plate and rolls on the plate, the abutting ball connected to the inner wall of the following ring rotates between the abutting ring and the lower pressure roller. This achieves the purpose of making it convenient for the adjusting frame to move simultaneously with the lower pressure roller, and making it convenient for the clamping wheel to adjust when the lower pressure roller abuts against plates of different thicknesses.

[0032] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0033] This application discloses a sheet metal cutting and clamping assembly.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A sheet metal cutting and clamping assembly includes a cutting table 1, on which two symmetrical movable support seats 3 are slidably connected. A movable support frame 2 is fixed between the two movable support seats 3. A cutting head 4 is slidably connected to the movable support frame 2. A cutting knife 9 is installed on the cutting head 4. Support rods 7 are fixed on both movable support seats 3. Two symmetrical lower pressure rollers 6 are arranged between the two support rods 7. Hydraulic telescopic rods 8 are arranged at both ends of the lower pressure rollers 6. The telescopic ends of the hydraulic telescopic rods 8 are rotatably connected to the lower pressure rollers 6. The hydraulic telescopic rods 8 are fixedly connected to the support rods 7. A clamping and stabilizing mechanism 5 is arranged on the lower pressure rollers 6. The clamping and stabilizing mechanism 5 includes two adjusting frames 53 symmetrically arranged on the lower pressure rollers 6. The adjusting frames 53 are U-shaped. Clamping wheels 52 are rotatably connected to both ends of the adjusting frames 53.

[0035] When cutting the sheet material, the sheet material is first placed on the cutting table 1. Then, the movable support 3 moves the cutting head 4 to the cutting position. The hydraulic telescopic rod 8 then moves the lower pressure roller 6 to contact the sheet material. At the same time, the two adjusting frames 53 of the clamping and stabilizing mechanism 5 move the clamping wheels 52 to contact the edge of the sheet material. Then, the cutting blade 9 contacts the sheet material and performs cutting. The movable support 3 moves the support rod 7, and the lower pressure roller 6 on the support rod 7 moves with the cutting blade. At the same time, the clamping wheels 52 also move. By having the hydraulic telescopic rod 8 move the lower pressure roller 6 to contact the sheet material on the cutting table 1, and the adjusting frames 53 of the clamping and stabilizing mechanism 5 move the clamping wheels 52 to contact the edge of the sheet material, the stability of the sheet material during cutting can be further improved, and the possibility of the sheet material shifting on the cutting table 1 can be further reduced.

[0036] Reference Figure 2 , Figure 3 and Figure 4 A clamping frame 51 is fixed between the two support rods 7. An adjusting component 54 is provided between the clamping frame 51 and the two adjusting frames 53. A connecting component 55 is provided on the two adjusting frames 53. A following component 56 is provided between the adjusting frame 53 and the lower pressure roller 6.

[0037] In addition, the connecting assembly 55 includes a second connecting rod 552 fixed on the adjusting frame 53, and a first connecting rod 551 is slidably connected to the second connecting rod 552.

[0038] Furthermore, a limiting groove 554 is provided on the first connecting rod 551, the limiting groove 554 passes through the first connecting rod 551, and a limiting block 553 is fixed at one end of the second connecting rod 552 near the first connecting rod 551. The limiting block 553 is located in the limiting groove 554 and is slidably connected to the first connecting rod 551.

[0039] Furthermore, the adjustment assembly 54 includes two sliding blocks 541 symmetrically arranged on the clamping frame 51. The clamping frame 51 has a sliding groove 542, and the two sliding blocks 541 are located in the sliding groove 542 and are fixedly connected to the corresponding connecting rod 551.

[0040] Furthermore, a bidirectional threaded rod 544 is rotatably connected to the clamping frame 51. The bidirectional threaded rod 544 is located in the sliding groove 542. The bidirectional threaded rod 544 passes through two sliding blocks 541 and is threadedly connected to the two sliding blocks 541. A drive motor 543 is fixed on the clamping frame 51. The output end of the drive motor 543 passes through the clamping frame 51 and is fixedly connected to the bidirectional threaded rod 544.

[0041] When the lower pressure roller 6 abuts against the plate, the lower pressure roller 6 drives the following assembly 56, which in turn drives the adjusting frame 53. The adjusting frame 53 then drives the connecting rod 2 552, which slides on the connecting rod 1 551. This allows the clamping wheel 52 on the adjusting frame 53 to be positioned at the edge of the plate. Simultaneously, the connecting rod 2 552 drives the limiting block 553, which restricts the connecting rod 2 552, reducing the possibility of the connecting rod 1 551 and the connecting rod 2 552 disengaging. After the clamping wheel 52 on the adjusting frame 53 is positioned at the edge of the plate, the drive motor 543 drives the bidirectional threaded rod 544, which in turn drives the two sliding blocks 541. This allows the two sliding blocks 541 to move simultaneously within the sliding grooves 542 on the clamping frame 51. The sliding block 541 drives the connecting rod 1 551, which in turn drives the connecting rod 2 552. The connecting rod 2 552 then drives the adjusting frame 53, which in turn drives the clamping wheel 52 to abut against the edge of the board. The clamping wheel 52 clamps the edge of the board. When cutting the board, the lower pressure roller 6 rolls on the board, and the clamping wheel 52 rolls on the edge of the board. By pressing the lower pressure roller 6 against the board, the sliding block 541 drives the adjusting frame 53, which in turn drives the clamping wheel 52 to abut against the edge of the board. This further improves the stability of the board during cutting and reduces the possibility of the board shifting when placed on the cutting table 1.

[0042] Reference Figure 3 and Figure 4 The following component 56 includes a connecting block 561 fixed to one side of the adjusting frame 53, and a following ring 562 fixed on the connecting block 561. The following ring 562 is sleeved on the lower pressure roller 6.

[0043] In addition, several abutting balls 563 are connected to the inner wall of the following ring 562, and the abutting balls 563 abut against the lower pressure roller 6.

[0044] When the hydraulic telescopic rod 8 drives the support rod 7 to press down onto the plate, the lower pressure roller 6 drives the following ring 562, the following ring 562 drives the connecting block 561, and the connecting block 561 drives the adjusting frame 53, causing the adjusting frame 53 to drive the connecting rod 2 552 to slide in the connecting rod 1 551. This allows the clamping wheel 52 on the adjusting frame 53 to move synchronously with the lower pressure roller 6. When the lower pressure roller 6 abuts against the plate and rolls on the plate, the abutting ball 563, which is rotatably connected to the inner wall of the following ring 562, rotates between the abutting ring and the lower pressure roller 6. By having the following ring 562 fitted onto the lower pressure roller 6, the lower pressure roller 6 moves, driving the following ring 562 to move. This allows the adjusting frame 53 to move simultaneously with the lower pressure roller 6, and allows the clamping wheel 52 to adjust accordingly when the lower pressure roller 6 abuts against plates of different thicknesses.

[0045] Working principle: When cutting the board, the board is first placed on the cutting table 1. Then, the movable support 3 moves the cutting head 4 to the cutting position. The hydraulic telescopic rod 8 then drives the lower pressure roller 6 to abut against the board. The lower pressure roller 6 drives the following ring 562, which in turn drives the connecting block 561. The connecting block 561 drives the adjusting frame 53, causing the adjusting frame 53 to slide the connecting rod 2 552 within the connecting rod 1 551. The clamping wheel 52 on the adjusting frame 53 moves synchronously with the lower pressure roller 6, positioning the clamping wheel 52 at the edge of the board. The drive motor 543 drives the bidirectional threaded rod 544, allowing... The bidirectional threaded rod 544 drives two sliding blocks 541, causing the two sliding blocks 541 to move simultaneously in the sliding grooves 542 on the clamping frame 51. The sliding blocks 541 drive the first connecting rod 551, which in turn drives the second connecting rod 552. The second connecting rod 552 drives the adjusting frame 53, which in turn drives the clamping wheel 52 to abut against the edge of the plate. The clamping wheel 52 clamps the edge of the plate, and then the cutting blade 9 contacts the plate for cutting. The moving support base 3 drives the support rod 7, causing the lower pressure roller 6 on the support rod 7 to move with the cutting blade, and the clamping wheel 52 also moves with it.
