[0002] A bending machine is a machine that can bend thin plates. During the operation of a bending machine, the thin plate to be bent is placed on the worktable, the upper bending die faces downward, and together with the lower bending die, the thin plate is bent. Hydraulic bending machines are widely used because of their advantages such as simple operation, low cost and fast response speed.
[0003] Traditional bending machines have fixed mold structures, and the mold changing process is cumbersome. If there is only a single machine, it is laborious to frequently change molds for different specifications and shapes of bending needs, which increases equipment downtime and costs.
[0004] Therefore, it is necessary to invent a sheet metal bending device to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sheet metal bending device, including a workbench, on which multiple sliding grooves are formed. A first moving block and a second moving block are connected within each sliding groove. The top of the first moving block has an installation groove, and a limit block is connected within the installation groove. Threaded openings are formed on the tops of the limit block and the first moving block, and locking bolts are connected to the threaded openings. A threaded rod is connected to the top of the second moving block. A strip-shaped opening corresponding to the threaded rod is formed on the limit block, and an adjusting bolt is connected to the outer wall of the threaded rod. An installation opening is formed on the top of the workbench, and a lower die is placed therein. A base is connected to the bottom of the workbench, and an L-shaped bracket is connected to the top of the base. An electro-hydraulic rod is connected to the top of the L-shaped bracket, and its output end passes through the L-shaped bracket and is connected to an installation plate. An installation seat is connected to the bottom of the installation plate, and an upper die is provided on the outer side of the installation seat. Multiple limit openings are formed on the outer sides of both the upper die and the installation seat, and limit bolts are connected to the limit openings.
[0007] Preferably, the upper mold has a slot corresponding to the mounting base.
[0008] Preferably, the first moving block and the second moving block can move independently.
[0009] Preferably, a pad is connected to the bottom of the limiting block, and the pad is made of rubber.
[0010] The technical effects and advantages of this utility model are as follows: By setting up a first moving block, a second moving block, a threaded rod, a locking bolt, an adjusting bolt, a lower mold, a mounting base, a limiting bolt, and an upper mold for coordinated use, the locking bolt fixes the limiting block on the first moving block, and the threaded rod of the second moving block passes through the slot of the limiting block. According to the shape and size of the lower mold, the position of the threaded rod in the slot is adjusted, and then the positions of the first and second moving blocks are adjusted. By rotating the adjusting bolt, the limiting block fixes the lower mold, and the corresponding lower mold is installed on the mounting base and fixed by the limiting bolt. This enables quick mold replacement, reducing equipment downtime and costs. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] This utility model provides, for example Figure 1-5The sheet metal bending device shown includes a workbench 1 with multiple sliding grooves. Each sliding groove houses a first moving block 2 and a second moving block 3. The top of the first moving block 2 has an installation groove, within which a limit block 4 is connected. The limit block 4 and the top of the first moving block 2 have threaded openings, with locking bolts 5 connected to the threaded openings. The top of the second moving block 2 is connected to a threaded rod 6. The limit block 4 has a corresponding slot on the threaded rod 6, and adjusting bolts 7 are connected to the outer wall of the threaded rod. The top of the workbench 1... The workbench 1 has an installation port, at which a lower mold 8 is placed. A base 9 is connected to the bottom of the workbench 1, and an L-shaped bracket 10 is connected to the top of the base 9. An electric hydraulic rod 11 is connected to the top of the L-shaped bracket 10. The output end of the electric hydraulic rod 11 passes through the L-shaped bracket 10 and is connected to a mounting plate 12. A mounting seat 13 is connected to the bottom of the mounting plate 12. An upper mold 14 is provided on the outside of the mounting seat 13. Multiple limiting holes are provided on the outside of both the upper mold 14 and the mounting seat 13. Limiting bolts 15 are connected to the limiting holes to fix the upper mold 14.
[0015] The upper mold 14 has a slot corresponding to the mounting base 13 for placing the upper mold 14.
[0016] The first moving block 2 and the second moving block 3 can move independently. There is a height difference between the first moving block 2 and the second moving block 3. Changing the distance between them can change the downward pressure effect of the limit block 4.
[0017] The bottom of the limiting block 4 is connected to a pad block 16, which is made of rubber to increase the friction on the lower mold and enhance the effect of fixing and limiting.
[0018] The working principle of this utility model is as follows: The locking bolt 5 fixes the limiting block 4 on the first moving block 2. The threaded rod 6 of the second moving block 3 passes through the slot of the limiting block 4. According to the shape and size of the lower die 8, the position of the threaded rod 6 in the slot is adjusted, and then the positions of the first moving block 2 and the second moving block 3 are adjusted. The adjusting bolt 7 is rotated so that the limiting block 4 fixes the lower die. The corresponding lower die 8 is installed on the mounting base 13 and fixed by the limiting bolt 15. After the installation of the upper and lower dies is completed, the plate is placed in the lower die 8. The electric hydraulic rod extends and drives the upper die 14 to move downward to punch the plate.
