Description

Technical Field

[0001] This utility model relates to the field of steel processing technology, and in particular to a bending mechanism for a bending machine. Background Technology

[0002] A bending machine is a device that can bend materials such as steel plates. In the process of using a bending machine, the workpiece is first placed in a suitable position on the lower die, and the upper die is driven to move downward so that the upper die contacts the workpiece placed on the lower die and applies pressure to achieve bending of the workpiece.

[0003] When using a bending machine to bend small workpieces, workers need to hold the workpiece and place it in a suitable position for bending. However, due to the small size of the workpiece, the distance between the worker's hands and the upper die of the bending machine is relatively close, which poses a certain safety risk when the worker presses down on the workpiece to bend it. Utility Model Content

[0004] The purpose of this invention is to provide a bending mechanism for a bending machine that reduces the safety risks for workers.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: it includes a machine body, an upper die cutter disposed on the machine body, and a lower die disposed on the machine body. The upper die cutter is located directly above the lower die. A detachable positioning component is disposed on one side of the lower die. The positioning component includes a plurality of positioning blocks that are detachably connected in sequence. A feeding platform is disposed at the top of the positioning block in a horizontal direction. The feeding platform is at the same horizontal plane as the top of the lower die.

[0006] A further feature of this invention is that: a plurality of first connecting blocks are arranged horizontally on the side of the positioning block near the lower mold; a plurality of first connecting grooves that mate with the first connecting blocks are opened on the side of the positioning block away from the lower mold; a plurality of second connecting grooves that mate with the first connecting blocks are opened horizontally on the side of the lower mold near the positioning block; and the longitudinal cross-sectional area of ​​the end of the first connecting block near the positioning block is smaller than the longitudinal cross-sectional area of ​​the end of the first connecting block away from the positioning block.

[0007] A further feature of this invention is that a limiting plate is movably provided on the machine body along the vertical direction, the lower mold is located between the positioning block and the limiting plate, and the machine body is provided with an adjusting component for driving the limiting plate closer to or further away from the lower mold.

[0008] A further feature of this invention is that the adjusting component includes an adjusting screw arranged horizontally on the machine body and a first rotating wheel arranged at the end of the adjusting screw. The limiting plate is connected to the adjusting screw. A second rotating wheel is rotatably arranged on the machine body. A synchronous belt is arranged between the first rotating wheel and the second rotating wheel. A drive motor for driving the second rotating wheel to rotate is arranged on the machine body.

[0009] A further feature of this invention is that a guide rod is provided on the machine body along a direction parallel to the adjusting screw, the guide rod movably passes through the limiting plate, and the guide rod and the adjusting screw are respectively located at both ends of the limiting plate.

[0010] A further feature of this invention is that a detachable first limiting block is provided vertically on the side of the lower mold near the positioning block, and a plurality of second connecting blocks that cooperate one by one with the second connecting groove are provided on the side of the first limiting block near the lower mold.

[0011] A further feature of this invention is that a second limiting block is vertically arranged at one end of the feeding platform near the first limiting block.

[0012] A further feature of this invention is that a third limiting block is vertically arranged on the side of the second limiting block near the first limiting block, and the side of the second limiting block near the first limiting block can be attached to the adjacent third limiting block.

[0013] A further feature of this invention is that: a plurality of moving grooves are provided on the machine body along a direction parallel to the adjusting screw, and a plurality of moving blocks corresponding one-to-one with the moving grooves are provided at the bottom end of the limiting plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up detachable positioning blocks and a feeding platform, when processing small workpieces, multiple positioning blocks are first connected sequentially according to the size of the small workpiece. Then, the positioning parts are connected to the lower mold. At this time, the feeding platform on the positioning parts is at the same height as the top of the lower mold. The worker places the small workpiece on the feeding platform, aligns the position to be processed with the upper mold cutter, and then the worker presses down on the end of the workpiece on the feeding platform to be bent. Compared with pressing down on the end of the workpiece directly on the lower mold, this increases the distance between the worker's hand and the upper mold cutter, and also reminds the worker not to place the hand on the lower mold, thereby reducing the safety risk of the worker's operation.

[0016] 2. By setting a first connecting block, a first connecting groove, etc., when connecting multiple positioning blocks, it is only necessary to connect the first connecting block of one positioning block along the direction of the first connecting groove. When connecting the positioning part and the lower mold, align the first connecting block at one end of the positioning part with the second connecting groove and move it along the second connecting groove to the processing location. Since the longitudinal cross-sectional area of ​​the end of the first connecting block away from the positioning block is greater than the longitudinal cross-sectional area of ​​the end of the first connecting block close to the positioning block, after the first connecting block is connected with the first connecting groove or the second connecting groove, the positioning block can only move along the direction of the first connecting groove or the second connecting groove. The positioning block cannot move outward, thereby realizing the detachable connection between multiple positioning blocks and the positioning block and the lower mold. The operation is simple and convenient.

[0017] 3. By setting a limit plate and adjusting the lead screw, when small workpieces need to be processed, the drive motor is turned on to drive the adjusting lead screw to rotate according to the position of the small workpiece to be processed. This drives the limit plate to move closer to or away from the lower die to a suitable position. When placing the small workpiece on the feeding platform, only the side of the workpiece to be processed needs to be pressed against the limit plate to align the position of the workpiece to be processed with the upper die cutter. This makes it easier for workers to position the small workpiece and thus improves processing efficiency. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] This utility model provides a bending mechanism for a bending machine, such as... Figures 1 to 6 As shown, the device includes a body 1, an upper die cutter 2 disposed on the body 1, and a lower die 3 disposed on the body 1. The upper die cutter 2 is located directly above the lower die 3. A detachable positioning component is provided on one side of the lower die 3. The positioning component includes several positioning blocks 4 that are detachably connected in sequence. A feeding platform 5 is provided at the top of the positioning block 4 in a horizontal direction. The feeding platform 5 and the top of the lower die 3 are on the same horizontal plane.

[0028] Furthermore, the positioning block 4 has a plurality of first connecting blocks 6 arranged horizontally on the side near the lower mold 3, and the positioning block 4 has a plurality of first connecting grooves 7 that mate with the first connecting blocks 6 one by one on the side away from the lower mold 3. The lower mold 3 has a plurality of second connecting grooves 8 arranged horizontally on the side near the positioning block 4 that mate with the first connecting blocks 6 one by one. The longitudinal cross-sectional area of ​​the end of the first connecting block 6 near the positioning block 4 is smaller than the longitudinal cross-sectional area of ​​the end of the first connecting block 6 away from the positioning block 4.

[0029] Furthermore, a limiting plate 9 is movably arranged on the body 1 along the vertical direction, the lower mold 3 is located between the positioning block 4 and the limiting plate 9, and the body 1 is provided with an adjusting member 10 for driving the limiting plate 9 to move closer to or away from the lower mold 3.

[0030] Furthermore, the adjusting component 10 includes an adjusting screw 10a arranged horizontally on the machine body 1 and a first rotating wheel 10b disposed at the end of the adjusting screw 10a. The limiting plate 9 is connected to the adjusting screw 10a. A second rotating wheel 11 is rotatably disposed on the machine body 1. A synchronous belt 12 is disposed between the first rotating wheel 10b and the second rotating wheel 11. A drive motor 13 for driving the second rotating wheel 11 to rotate is disposed on the machine body 1.

[0031] Furthermore, a guide rod 14 is provided on the body 1 in a direction parallel to the adjusting screw 10a. The guide rod 14 moves through the limiting plate 9, and the guide rod 14 and the adjusting screw 10a are located at the two ends of the limiting plate 9, respectively.

[0032] Furthermore, a detachable first limiting block 15 is provided on the side of the lower mold 3 near the positioning block 4 in the vertical direction, and a plurality of second connecting blocks 16 are provided on the side of the first limiting block 15 near the lower mold 3 to cooperate with the second connecting groove 8 one by one.

[0033] Furthermore, a second limiting block 17 is vertically arranged at one end of the feeding platform 5 near the first limiting block 15.

[0034] Furthermore, a third limiting block 18 is vertically arranged on the side of the second limiting block 17 near the first limiting block 15, and the side of the second limiting block 17 near the first limiting block 15 can be attached to the adjacent third limiting block 18.

[0035] Furthermore, the machine body 1 has several moving grooves 19 along a direction parallel to the adjusting screw 10a, and the bottom end of the limiting plate 9 is provided with several moving blocks 20 corresponding to the moving grooves 19 one by one.

[0036] When processing small workpieces, firstly, multiple positioning blocks 4 are connected sequentially through the first connecting block 6 and the first connecting groove 7 according to the size of the small workpiece. Then, the positioning part is connected to the lower mold 3 through the first connecting block 6 and the second connecting groove 8. At this time, the feeding platform 5 on the positioning part is at the same height as the top of the lower mold 3. The worker places the small workpiece on the feeding platform 5, so that one side of the workpiece abuts against the limiting plate 9. At this time, the position to be processed is aligned with the upper mold cutter 2. Then, the worker can press down on the end of the workpiece located on the feeding platform 5 to bend it. Compared with pressing down on the end of the workpiece directly on the lower mold 3, this can increase the distance between the worker's hand and the upper mold cutter 2, and at the same time, it can remind the worker not to place the hand on the lower mold 3, thereby reducing the safety risk of the worker's operation.

[0037] By setting a first connecting block 6, a first connecting groove 7, etc., when connecting multiple positioning blocks 4, it is only necessary to connect the first connecting block 6 of one positioning block 4 along the direction of the first connecting groove 7. When connecting the positioning component and the lower mold 3, the first connecting block 6 at one end of the positioning component is aligned with the second connecting groove 8 and moved along the second connecting groove 8 to the processing location. Since the longitudinal cross-sectional area of ​​the end of the first connecting block 6 away from the positioning block 4 is greater than the longitudinal cross-sectional area of ​​the end of the first connecting block 6 close to the positioning block 4, after the first connecting block 6 is connected with the first connecting groove 7 or the second connecting groove 8, the positioning block 4 can only move along the direction of the first connecting groove 7 or the second connecting groove 8. The positioning block 4 cannot move outward, thereby realizing the detachable connection between multiple positioning blocks 4 and the positioning block 4 and the lower mold 3. The operation is simple and convenient.

[0038] By setting a limiting plate 9 and adjusting screw 10a, when a small workpiece needs to be processed, the drive motor 13 is turned on to drive the adjusting screw 10a to rotate according to the position of the small workpiece to be processed. This drives the limiting plate 9 to move closer to or further away from the lower die 3 to a suitable position. When the small workpiece is placed on the feeding platform 5, only the side of the workpiece to be processed needs to be pressed against the limiting plate 9 to align the position of the workpiece to be processed with the upper die cutter 2. This makes it easier for workers to position the small workpiece and thus improves processing efficiency.

[0039] By setting the first limiting block 15, the first limiting block 15 can be moved to determine the position where the positioning part is connected to the lower mold 3. Then, the first connecting block 6 on the positioning part is aligned with the second connecting groove 8, and the positioning part is moved until one side of the positioning part abuts against the first limiting block 15, thereby facilitating the determination of the connection position between the positioning part and the lower mold 3.

[0040] By setting the second limiting block 17, when the workpiece is placed on the feeding platform 5, one side of the workpiece can abut against the second limiting block 17, thereby further limiting the workpiece and making it easier for workers to perform bending operations.

[0041] By setting a third limiting block 18, when connecting multiple positioning blocks 4, the first connecting block 6 of one positioning block 4 is aligned with the first connecting groove 7 of another positioning block 4 and the positioning block 4 is moved until the second limiting block 17 abuts against the third limiting block 18 on the adjacent positioning block 4. At this time, the second limiting blocks 17 on the two positioning blocks 4 are also aligned, which facilitates the mutual connection between multiple positioning blocks 4.

[0042] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0043] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
