Description

Technical Field

[0001] This utility model relates to the field of automotive inspection tool technology, specifically a steel mesh bending machine. Background Technology

[0002] The civil defense net is made of steel bars with a large diameter welded together. In order to increase the strength of the ends, the four sides of the civil defense net are bent to one side.

[0003] Currently, civil defense nets are welded using welding machines. After welding, the netting is fixed on the workbench, and the ends of the reinforcing bars are bent manually. This method has the following drawbacks: First, due to the large diameter, manual bending is labor-intensive and inefficient. Second, during bending, different bending points result in uneven sides of the civil defense netting, affecting its use. Third, different bending angles at the ends of the reinforcing bars can easily cause bending of the reinforcing bars on the netting surface, resulting in poor flatness of the netting.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a steel mesh bending machine, comprising: support legs 6 fixed at both ends of a strip cylinder 1, a support plate 7 fixedly installed at the end of the support leg 6 away from the strip cylinder 1, the support plate 7 connecting the support legs 6 on one side of the strip cylinder 1 together, enhancing the stability of the support legs 6 and supporting the strip cylinder 1 more stably, a strip groove 2 is opened at the upper end of the strip cylinder 1, the strip groove 2 is connected to the inner end of the strip cylinder 1, a plurality of limiting grooves 3 are evenly fixedly installed at the upper end of the strip cylinder 1, a driving component is provided inside the strip cylinder 1, a plurality of connecting blocks 17 are evenly slidably connected inside the strip cylinder 1, the upper end of the connecting block 17 extends out of the strip groove 2 and is fixedly installed with a pressure plate 18, the driving component is used to drive the connecting block 17 and the pressure plate 18 to move.

[0023] The driving component includes a sliding plate 11 and a rotating rod 13. A threaded sleeve 12 is fixedly installed at one end of the sliding plate 11. The left and right ends of the rotating rod 13 are rotatably connected to the strip cylinder 1 through bearings. A threaded groove 14 is provided on the outer wall of the rotating rod 13. The threaded sleeve 12 is sleeved on the outer end of the rotating rod 13 and threadedly connected to the threaded groove 14. A motor 10 is fixedly installed at one end of the strip cylinder 1. The output end of the motor 10 is fixedly connected to one end of the rotating rod 13 through a coupling. The motor 10 can drive the rotating rod 13 to rotate in both directions. When the rotating rod 13 rotates, it can drive the threaded sleeve 12 to move along the connecting block 17 and the pressure plate 18 at the upper end of the strip cylinder 1.

[0024] Several electric push rods 15 are fixedly installed at the end of the slide plate 11 away from the threaded sleeve 12. A slide plate 16 is fixedly installed at the end of the electric push rod 15 away from the slide plate 11. The front and rear ends of the slide plate 16 and the slide plate 11 are slidably connected to the inner wall of the strip cylinder 1. The lower ends of several connecting blocks 17 are fixed to the upper end of the slide plate 16. When the electric push rods 15 are started, they can drive the slide plate 16 to connect the connecting blocks 17 and the pressure plate 18 in the vertical direction.

[0025] A number of hydraulic cylinders 8 are provided at one end of the strip cylinder 1. One end of the hydraulic cylinder 8 is fixed on the outer wall of the strip cylinder 1, and the other end is connected to a bending roller 9 through a bearing shaft. When the hydraulic cylinder 8 is started, it can drive the bending roller 9 to move upward. During the upward movement of the bending roller 9, it contacts the steel mesh and pushes and bends the steel mesh upward.

[0026] Specifically, the steel mesh to be bent is placed at the upper end of the strip cylinder 1 and fitted onto the outer end of the pressure plate 18. The transverse steel bars of the steel mesh can be located in the limiting groove 3 for initial limiting. Then, the motor 10 is started to drive the connecting block 17 and the pressure plate 18 to move, moving the pressure plate 18 to the upper end of the steel mesh. Then, the electric push rod 15 is started to pull down the slide plate 16. The slide plate 16 slides down in the strip cylinder 1, simultaneously pressing down the connecting block 17 and the pressure plate 18. The pressure plate 18 contacts the upper end of the steel mesh and fixes it. Then, the hydraulic cylinder 8 is started to drive the bending roller 9 to move upward. During the upward movement of the bending roller 9, it contacts the steel mesh and pushes and bends the steel mesh upward.

[0028] like Figure 2 and Figure 3 As shown, in some embodiments, the end of the pressure plate 18 near the bending roller 9 is flush with the outer end of the strip cylinder 1. More specifically, when the hydraulic cylinder 8 drives the bending roller 9 to move upward, the bending roller 9 and the outer end of the pressure plate 18 are closer together, which can make the arc of the steel mesh bending smaller and the bending smoother.

[0029] In actual use, the steel mesh to be bent is placed at the upper end of the strip cylinder 1, and then the motor 10 is started to drive the connecting block 17 and the pressure plate 18 to move. The pressure plate 18 is moved to the upper end of the steel mesh, and then the electric push rod 15 is started to pull the pressure plate 18 down. The pressure plate 18 contacts the upper end of the steel mesh and fixes it. Then the hydraulic cylinder 8 is started to drive the bending roller 9 to move upward. During the upward movement of the bending roller 9, it contacts the steel mesh and pushes the steel mesh upward and bends it.
