Description

Technical Field

[0001] The utility model relates to the technical field of round rolling machines, in particular to a low-noise round rolling machine. Background Art

[0002] Rolling machines are divided into mechanical and hydraulic types. Mechanical rolling machines are high-quality and high-efficiency rolling devices that roll carbon steel, stainless steel, and yellow metal profiles into rings and flanges. They have unique structures and are small in size, low in energy consumption, high in efficiency, easy to install and use, simple to operate, strong in bearing capacity, long in life, fast in rolling speed, and reliable in product quality. Hydraulic rolling machines are upgraded products of mechanical rolling machines. They can increase the thickness and width of the rolls, and can solve the problem that mechanical rolling cannot roll thick plates. They replace the original complex processes of steel plate cutting, docking, correction, lathe processing, etc., and save oxygen, acetylene, labor, raw materials, etc. They are advanced mother bodies for manufacturing flanges. Existing rolling machines have the disadvantages of poor sound absorption, no reserve function, and low rolling efficiency.

[0003] A low-noise rolling machine with publication number CN207372085U improves the sound absorption performance of the equipment by arranging a sound-absorbing panel on the surface of the bracket; by arranging a hidden compartment, the equipment has the function of storing items. The low-noise rolling machine adopts 1 upper pressing wheel and 2 lower pressing wheels to make angle steel, strip steel and other steel materials into a round shape through the mutual extrusion between the upper pressing wheel and the lower pressing wheel. The diameter of the rolled steel material is adjusted by the adjusting disk, thereby improving the rolling efficiency.

[0004] When the above-mentioned low-noise rolling machine is in use, a sound-absorbing plate is installed on the surface of the bracket. When the plate is rolled between the pressing wheels, the plate will shake and generate noise due to the different diameters of the plate and the pressing wheels. Utility Model Content

Support plates 3 are installed at both ends of the three pressing wheels 2. The bottom end of the support plate 3 is fixedly connected to the top of the processing base 1 for supporting the three pressing wheels 2 for use. A driving component is fixedly arranged on the support plate 3 close to the pressing wheel 2. The driving component includes a motor component 15 for driving the pressing wheel 2 to rotate. The bottom end of the motor component 15 is fixedly connected to the top of the processing base 1 for driving the pressing wheel 2 to rotate for rolling processing. A noise reduction component is arranged on the side close to each other of the two support plates 3.

[0023] Specifically, each noise reduction component includes three mounting plates 4, each mounting plate 4 has a mounting hole 5 on its inner side, a guide roller 6 is provided in the mounting hole 5, and the guide roller 6 is used to limit the side of the plate to prevent the plate from shifting when rolling. The front and rear ends of each guide roller 6 are connected to the inner wall of the mounting hole 5 through bearings, so that the guide roller 6 can rotate in the mounting hole 5 to reduce the friction between the guide roller 6 and the plate. The three mounting plates 4 are connected together by connecting blocks 7, and the tops of the two support plates 3 are fixed with adjustment components for adjusting the position of the mounting plates 4.

[0024] By using the adjustment component to adjust the position of the mounting plate 4, the staff adjusts the distance between the two groups of mounting plates 4 according to the width of the processed plate, so that the guide roller 6 on the mounting plate 4 contacts the side wall of the plate. When the plate is rolled between the three pressing wheels 2, the guide rollers 6 on the left and right sides guide and support the side wall of the plate, which can avoid the plate from shifting when rolling, thereby preventing the plate from bending and rubbing against the pressing wheel 2 when rolling to generate noise. The guide roller 6 is installed in the mounting hole 5 through a bearing. When the plate contacts the guide roller 6, the guide roller 6 rotates without generating friction with the plate, thereby avoiding the generation of noise.

[0025] Refer to the instruction manual Figure 1-5 The utility model provides a low-noise rolling machine. Both adjustment components include a first hydraulic cylinder 8. The two first hydraulic cylinders 8 are respectively fixed on the tops of the two support plates 3. The first hydraulic cylinders 8 are used to drive the mounting plate 4 to move left and right. The first hydraulic cylinder 8 is fixed with a second hydraulic cylinder 10 through a first connecting plate 9 on one side close to the mounting plate 4. The top of the second hydraulic cylinder 10 is fixedly connected to the mounting plate 4 through a second connecting plate 11, so as to adjust the up and down position of the mounting plate 4.

[0026] Two support blocks 12 distributed front and back are embedded on the top of the two support plates 3. A through hole 13 is opened in the support block 12. A guide rod 14 runs through the through hole 13. One end of the guide rod 14 is fixedly connected to the mounting plate 4. The guide rod 14 and the support block 12 are used in conjunction to increase the stability of the mounting plate 4 when moving.

[0027] By using the second hydraulic cylinder 10 to adjust the height of the mounting plate 4, the first hydraulic cylinder 8 can drive the mounting plate 4 to move left and right, and adjust the spacing between the two groups of mounting plates 4 without manual operation, which saves time and effort. When the mounting plate 4 moves left and right, the guide rod 14 on the mounting plate 4 slides in the through hole 13, which can increase the stability of the mounting plate 4 when moving. When the mounting plate 4 moves up and down, the support block 12 follows the guide rod 14 and moves simultaneously in the support plate 3, continuing to guide the mounting plate 4.
