Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically to a positioning fixture for bending machines used in the production of metal casings. Background Technology

[0002] A bending machine is a device used to bend and shape sheet metal (such as metal and plastic). In the processing of metal casings, a bending machine can bend and fold flat metal sheets according to design requirements to form the desired three-dimensional shape and structure of the metal casing. By using different molds and adjusting bending parameters (such as angle and position), various complex-shaped casing components can be processed.

[0003] When bending sheet metal with existing bending machines, users need to hold one end of the sheet metal by hand to prevent it from shifting and causing bending deviations during the bending process. This operation has certain safety hazards. The sheet metal may warp during bending, which can easily injure the user. Moreover, the user's manual positioning can easily cause some positional deviations, affecting the bending quality. Utility Model Content

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0026] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0027] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] Combined with appendix Figure 1 and Figure 5 As shown, a positioning fixture for a bending machine used in the production of metal casings includes a worktable 1, on which a bending assembly is provided. An axially movable positioning assembly is located on one side of the bending assembly on the worktable 1. The positioning assembly includes a movable seat 2, which has a cavity. A plurality of air holes 3 communicating with the cavity are arrayed on the upper surface of the movable seat 2. A vacuum pump 4 is fixedly mounted on the side of the movable seat 2, and an air pipe 5 communicating with the cavity is connected to the vacuum pump 4. A sliding groove 6 is provided on the worktable 1, and a screw 7 is rotatably connected within the sliding groove 6. A connecting seat 8 is provided at the bottom of the movable seat 2, slidingly located within the sliding groove 6 and threadedly connected to the screw 7. A motor 9 is located on one side of the worktable 1, and the output end of the motor 9 is connected to the screw 7.

[0029] At the same time, combined with the appendix Figure 2 , Figure 4 and Figure 6 As shown, the workbench 1 has two slide grooves 19 on both sides of the slide groove 1 6, and the bottom of the movable seat 2 is symmetrically connected with movable wheels 20. The movable wheels 20 slide within the slide groove 19. The movable wheels 20 can share the force of the screw 7 and extend the service life of the screw 7. The workbench 1 is symmetrically provided with length marking lines 21, and the movable seat 2 is provided with indicator arrows 22.

[0030] During the bending operation, one end of the sheet metal is placed on the movable seat 2. The vacuum pump 4 is started to create a negative pressure at the contact point between the sheet metal and the movable seat 2, which quickly adsorbs and fixes the sheet metal to be bent, preventing misalignment during the bending operation and ensuring accurate bending position. The motor 9 drives the screw 7 to rotate, which allows the movable seat 2 to move axially along the slide groove 6, thereby moving the sheet metal to any position and adjusting the bending position. At the same time, the indicator arrow 22 indicates the length marking line 21, which allows for a direct understanding of the sheet metal movement length, enabling more precise bending of the sheet metal.

[0031] Among them, the combination of appendix Figure 2 and Figure 3 As shown, the bending assembly includes a support frame 10 fixedly mounted on a workbench 1. A hydraulic cylinder 11 is mounted on the support frame 10. The telescopic end of the hydraulic cylinder 11 is connected to a mounting base 12. A mounting base 2 13 is located directly below the mounting base 12 on the workbench 1. A bending die 14 and a bending die 2 15 are respectively engaged in the mounting base 12 and the mounting base 2 13. The bending die 14 and the bending die 2 15 are matched. A slot 16 is provided on the mounting base 12. Multiple limiting slots 17 are arrayed on both sides of the slot 16. A locking block 18 matching the limiting slot 17 is provided on the bending die 14. The mounting base 2 13 has the same structure as the mounting base 12. An electromagnet 23 is embedded in both the mounting base 12 and the mounting base 2 13. The bending die 14 and the bending die 2 15 are made of iron.

[0032] The hydraulic cylinder 11 can drive the mounting base 12 to move to the mounting base 13 to bend the sheet metal. The setting of the limiting groove 17 can limit the forward and backward movement of the bending die. At the same time, the electromagnet 23 is used to attract and fix the bending die, which can facilitate the replacement of the bending die and thus improve the bending efficiency.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
