Description

Technical Field

[0001] The utility model relates to the technical field of steel bar straightening equipment, in particular to a multi-purpose steel bar bending and straightening machine. Background Art

[0002] Correction of shape defects of metal plastic processing products is one of the important finishing processes. Various shape defects often occur in the rolling process or in the subsequent cooling and transportation process, such as bending of bars, profiles and pipes, bending, wave, and bend of plates and strips. Various straightening processes can eliminate defects such as bending under the action of external forces. In the production and processing of steel bars, steel bar bending and straightening machines are needed to straighten the steel bars.

[0003] When using existing steel bar straightening machines, they can usually only straighten steel bars of a certain diameter. When steel bars of another diameter need to be straightened, the original straightening rollers need to be removed first, and then new and suitable straightening rollers need to be reinstalled. This is not only cumbersome to operate, but also time-consuming to disassemble and assemble the straightening rollers back and forth, which affects the efficiency of steel bar straightening. In this regard, we propose a multi-purpose steel bar bending and straightening machine to solve the above problems. Utility Model Content

[0022] A base 1, on the top wall of which a steel bar conveyor 2 is fixedly mounted, the steel bar conveyor 2 is an existing public technology, and the specific structure is not described in detail. A support plate 3 is fixedly welded to the rear end of the top wall of the base 1 on one side of the steel bar conveyor 2, and a driving mechanism 4 is arranged on the support plate 3, and two pairs of rotating columns 5 are rotatably mounted on the support plate 3, and rotating rods 6 are fixedly mounted on the front ends of the two pairs of rotating columns 5, and sliding sleeves 7 are slidably connected to the rotating rods 6, and a plurality of straightening rollers 8 are fixedly mounted on the sliding sleeves 7, and the straightening grooves of the plurality of straightening rollers 8 have different diameters, and a connecting seat 9 is arranged on the front end of each pair of the sliding sleeves 7, and the front end of the sliding sleeves 7 is rotatably mounted on the connecting seat 9, and a first connecting rod 10 is fixedly welded on two of the connecting seats 9, and the number of the driving mechanisms 4 is two, and the driving mechanism 4 includes a driving motor 11 and a pair of gears 12.

[0023] The driving motor 11 is fixedly mounted on the supporting plate 3, a pair of the gears 12 are fixedly mounted on the rear ends of a pair of rotating columns 5, the pair of gears 12 are meshed and connected, and the output shaft of the driving motor 11 is fixedly mounted on a gear 12. After the driving motor 11 is started, it can drive the corresponding gear 12 to rotate, and drive the rotating column 5 to rotate, thereby driving the rotating rod 6 to rotate. When the rotating rod 6 rotates, it drives the straightening roller 8 to rotate through the rotating sleeve 7. Through the meshing connection of the pair of gears 12, each pair of straightening rollers 8 can rotate in the opposite direction to straighten the steel bars.

[0024] A cross bar 13 is fixedly welded on the front side wall of the base 1, and a sliding rod 14 is slidably connected to the cross bar 13. A second connecting rod 15 is fixedly welded on the rear side wall at the top end of the sliding rod 14. The rear end of the second connecting rod 15 is fixedly welded to the first connecting rod 10. The sliding rod 13 can slide on the cross bar 13 to drive the second connecting rod 15 to move. The second connecting rod 15 drives the connecting seat 9 to move by connecting with the first connecting rod 10, thereby driving the sliding sleeve 7 to slide on the rotating rod 6 to adjust the straightening roller 8.

[0025] The slide bar 14 is provided with a limit assembly, which includes a fixed seat 16, which is fixedly welded to the front side wall of the slide bar 14, and a limit rod 17 is slidably connected to the fixed seat 16, and a pull plate 18 is fixedly welded to the top of the limit rod 17, and a spring 19 is sleeved on the limit rod 17, and both ends of the spring 19 are fixedly bonded to the fixed seat 16 and the pull plate 18 respectively.

[0026] The cross bar 13 is provided with a plurality of limit grooves 20, which are matched with the limit rod 17. The pulling force of the spring 19 on the pull plate 18 can drive the limit rod 17 to slide downward and insert into the corresponding limit groove 20 to limit the slide bar 14, thereby facilitating the limit fixation of the straightening roller 8 after adjustment.
