[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figure 1-Figure 4 A steel bar processing and bending device is shown, comprising:

[0026] A central axis 1, a support axis 2 is fixedly connected to the middle of the central axis 1, support plates 3 are rotatably connected to the two sides of the support axis 2, a bottom plate 4 is fixedly connected to the bottom of the support plate 3, a fixing plate 5 is fixedly connected to one side of the central axis 1, a connecting plate 6 is fixedly connected to the bottom of the fixing plate 5, and a hollow rod 15 is fixedly connected to the other side of the central axis 1;

[0027] The steel bar positioning component includes a support seat 8 and a pressing block 9. A connecting rod 7 is fixedly connected to one side of the support seat 8. Screw holes 11 are provided on both sides of the top of the support seat 8. Screw rods 10 are threadedly connected to the four corners of the top surface of the pressing block 9. The bottom of the screw rod 10 is threadedly connected to the inner wall of the screw hole 11. The bottom of the pressing block 9 fits the top of the support seat 8. The end of the connecting rod 7 away from the support seat 8 is fixedly connected to the surface of the connecting plate 6. A driving component is arranged above the side of the hollow rod 15 away from the fixing plate 5. When fixing the front end of the steel bar, the position of the pressing block 9 pressing the steel bar can be changed, so that the length of the steel bar passing through the bottom of the support shaft 2 can be freely changed within a certain range, and can be bent near the front end of the steel bar or in the middle area of ​​the steel bar.

[0028] Furthermore, the driving assembly includes a push rod motor 20, both sides of which are fixedly connected to support plates 19, the bottom of the support plate 19 is fixedly connected to the top of the base plate 4, the bottom of the push rod of the push rod motor 20 is fixedly connected to a slider 21, the middle part of the slider 21 is fixedly connected with a limit rod 22, and the slider 21 and the limit rod 22 act as a movable connection.

[0029] Furthermore, the inner wall of the hollow rod 15 is slidably connected with a slide rod 16, a slide groove 17 is provided on the top of the slide rod 16, and limiting grooves 18 are provided on both sides of the inner wall of the slide groove 17. The slide groove 17 and the limiting groove 18 play a limiting role, so that the slider 21 and the limiting rod 22 remain connected to the slide rod 16.

[0030] Furthermore, the bottom and both sides of the slider 21 are slidably connected to the inner walls of the slide groove 17, and both sides of the limit rod 22 are slidably connected to the inner walls of the limit groove 18. The limit rod 22 is in the limit groove 18 to prevent the slider 21 from slipping off the slide groove 17.

[0031] Furthermore, a support rod 13 is fixedly connected to the top of the bottom plate 4, and a second support seat 14 is fixedly connected to the top of the support rod 13. The second support seat 14 supports the steel bars.

[0032] Furthermore, one side of the support seat 1 8 fits with one side of the support seat 2 14 and the fitting portion is located directly below the support shaft 2. The support shaft 2 serves as a blocking support for the steel bars, and the support shaft 2 is the bending point.

[0033] Furthermore, the bottom of the pressing block 9 is fixedly connected with an anti-skid protrusion 12, and the anti-skid protrusion 12 is pressed on the surface of the steel bar to further improve the fixing effect.

[0034] Through the above technical solution:

[0035] Place the steel bar on the support seat 2 14 first, then push the steel bar to move to the support seat 1 8 so that the steel bar passes under the support shaft 2. When the part of the steel bar to be bent moves to the bottom of the support shaft 2, stop pushing, place the pressing block 9 at the front end of the steel bar so that the bottom of the pressing block 9 fits the top of the support seat 1 8, then rotate the screw 10 to screw the bottom of the screw 10 into the corresponding screw hole 11, use the pressing block 9 and the support seat 1 8 to clamp the front end of the steel bar, and press the anti-slip convex point 12 on the surface of the steel bar to further improve the clamping stability, and then drive the push rod motor 20 to push the slider 21 downward. When the slider 21 moves downward, it pushes the sliding rod 16 and the hollow rod 15 to rotate downward, and the sliding rod 16 slides out of the hollow rod 15, and the limiting rod 22 rotates in the limiting groove 18. When the hollow rod 15 rotates downward, the fixing plate 5 rotates upward through the connecting plate 6 and the connecting plate The connecting rod 7 drives the support seat 8 to deflect upward. At this time, the support shaft 2 plays a supporting and blocking role, blocking the area to be bent of the steel bar, and the support seat 8 bends the steel bar. At this time, the non-bending area is supported by the support seat 2 14 and the support seat 8, so that the non-bending area of ​​the steel bar can maintain a straight state and avoid bending. This solves the problem that the contact surface between the bent steel bar and the steel bar is very small, and when the steel bar is bent, the stress is concentrated on the contact point, making the straight section of the steel bar easy to bend. By setting the pressing block 9, the screw rod 10 and the screw hole 11, the position of the pressing block 9 pressing the steel bar can be changed when fixing the front end of the steel bar, so that the length of the steel bar passing through the bottom of the support shaft 2 can be freely changed within a certain range, and it can be bent near the front end of the steel bar, and it can also be bent in the middle area of ​​the steel bar, thereby improving flexibility.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
