Description

Technical Field

[0001] The utility model relates to the field of bending devices, in particular to a bending roll radian adjusting mechanism. Background Technique

[0002] Bending rolls are industrial equipment, usually used for bending metal sheets or metal pipes. They are mainly used to manufacture metal workpieces, such as pipes, pipe elbows, channel steels, round steels, etc., to meet various engineering and manufacturing requirements. Radian adjustment is a very important step when using bending rolls. By adjusting the position of the bending rolls and the setting of the roll edges, the bending radius and bending angle of the metal material can be precisely controlled. Different projects and workpieces may require different bending curvatures and shapes, so adjusting the radian can ensure that the final product meets the design requirements.

[0003] Traditional two-roll machines consist of a base, a drive system, roll shafts and a fixed roll shaft spacing. Among them, the drive system drives the roll shafts to rotate through a motor or manual force, while the support roll shafts are in fixed positions. Operators can usually only indirectly affect the pressure and processing effect during the processing by adjusting the rotation speed of the drive system, and cannot directly adjust the distance between the roll shafts. This makes this type of machine have certain limitations when processing sheets of different thicknesses or different diameters. The inability to adjust its position and angle limits the bending ability and flexibility of the machine. Therefore, a bending roll radian adjusting mechanism is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a bending roll radian adjusting mechanism, aiming to improve the problem that the upper roll in the prior art is fixedly installed and inconvenient to adjust.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0031] By starting the motor 11, the rotating shaft 9 can be prompted to start rotating. The rotation of the rotating shaft 9 further drives the limiting plate 10 fixed on the side wall to rotate. The limiting column 7 slides inside the limiting plate 10. The limiting plate 10 and the limiting column 7 engage with each other, so that the rotating disk 6 starts to rotate. As the rotating disk 6 rotates, the upper roller 3 and the lower roller 4 also start to rotate, and the material is squeezed and bent. When facing materials of different thicknesses, the handle 13 can be rotated to move the slide plate 5 upward, thereby raising the upper roller 3. In this way, the extrusion spacing can be adjusted to adapt to materials of different thicknesses.

[0032] Reference Figure 2 and Figure 3 The side wall of the frame 1 is fixedly connected with a feed platform 14, a slide plate 16 is fixedly connected to the lower surface of the feed platform 14, a slider 17 is slidably connected inside the slide plate 16, a connecting plate 18 is fixedly connected to the side wall of the slider 17, a clamping plate 19 is fixedly connected to the upper surface of the connecting plate 18, a fixed frame 21 is fixedly connected inside the frame 1, a hydraulic rod 20 is fixedly connected inside the fixed frame 21, and the output end of the hydraulic rod 20 is fixedly connected to the side wall of the connecting plate 18 on one side, a transverse groove 15 is opened inside the feed platform 14, the side wall of the clamping plate 19 is slidably connected inside the transverse groove 15, a rack 22 is fixedly connected to the side wall of the connecting plate 18, a fixed frame 23 is fixedly connected to the lower surface of the feed platform 14, a fixed column 24 is fixedly connected inside the fixed frame 23, a gear 25 is rotatably connected to the side wall of the fixed column 24, and the side wall of the rack 22 is slidably connected inside the fixed frame 23, and the gear 25 is meshed with the rack 22;

[0033] The material to be processed is placed on the feeding platform 14, and then the hydraulic rod 20 is started. After starting, the hydraulic rod 20 will push the connecting plate 18 to move through its power output. The movement of the connecting plate 18 will cause the slider 17 fixed on its side wall to start sliding inside the transverse groove 15. At the same time, the movement of the connecting plate 18 will also cause the rack 22 fixed on its side wall to start sliding. The rack 22 slides inside the fixed frame 23 and meshes with the gear 25 fixed on the side wall of the fixed column 24. The meshing rotation of the rack 22 and the gear 25 will cause the splint 19 to start sliding inside the transverse groove 15. The splint 19 has the effect of restricting both sides of the material during the sliding process, so that it remains in a parallel state and is transported to the inside of the extrusion roller.

[0034] Working principle: When using the device, the motor 11 is started to make the rotating shaft 9 start to rotate, and then the limiting piece 10 fixed on the side wall rotates accordingly, and the limiting piece 10 is meshed with the limiting column 7, so that the rotating disk 6 rotates. With the rotation of the rotating disk 6, the upper roller 3 and the lower roller 4 rotate to extrude and bend the material. When facing materials of different thicknesses, the handle 13 can be rotated to move the slide plate 5 upward to make the upper roller 3 rise, so as to adjust the extrusion spacing. Put the material on the feeding platform 14, and then start the hydraulic rod 20 to push the connecting plate 18. The movement of the connecting plate 18 makes the slider 17 fixed on the side wall slide inside the transverse groove 15. The movement of the connecting plate 18 makes the rack 22 fixed on the side wall start to slide. The rack 22 slides inside the fixed frame 23 and meshes with the gear 25. The rack 22 meshes and rotates with the gear 25, so that the clamping plate 19 slides inside the transverse groove 15, clamps the material and transports it to the inside of the extrusion roller in parallel.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
