Description

Technical Field

[0001] The present invention belongs to the technical field of metal processing, and particularly relates to a rolling device for metal product processing. Background Art

[0002] The rolling device for metal product processing is a key equipment for rolling metal billets into required shapes, and is widely used in the forming of metal materials such as pipes and plates. The rolling process can be divided into cold rolling and hot rolling. The former is carried out at room temperature, while the latter requires heating the metal billet to improve plasticity. The core component of the traditional rolling device is the roll group, which realizes continuous pressing of the metal billet through the cooperation of the working roll and the backup roll.

[0003] However, the existing rolling devices have the following significant defects: Low maintenance efficiency: The roll group is usually embedded inside the frame. Disassembly and assembly require a large number of related components to be removed, resulting in overly long maintenance time and seriously affecting production efficiency; Insufficient adjustment flexibility: The adjustment of the working roll spacing mostly relies on complex mechanical structures, with slow response speed and difficulty in meeting the rapid switching requirements of billets with different thicknesses; Limited guiding accuracy: The position of the traditional guiding structure is fixed and cannot dynamically match billets with different widths, easily causing rolling deviation or material waste; Therefore, it is necessary to design a rolling device for metal product processing to solve the above problems.

The cross-sectional shape of the connecting frame 22 is set to be T-shaped. The connecting frame 22 is inserted into the inner side of the pressing-down seat 35. An upper adjustment groove 25 is opened on the inner side of the mounting frame 21. The upper roller frame 23 is slidably installed in the upper adjustment groove 25. And an opening is provided at the upper end of the mounting frame 21. The connecting frame 22 passes through the opening and is connected to the pressing-down seat 35.

[0023] For the pressing-down structure 3 adopting the above technical solution, during use, it is connected by clamping the connecting frame 22 in the pressing-down seat 35. During use, the pressing-down motor 31 is driven to rotate the pressing-down screw rod 33 as needed, so that the pressing-down screw rod 33 drives the pressing-down nut 32 and the pressing-down rod 34 to move, and one end of the pressing-down rod 34 rotates to drive the pressing-down seat 35 to rise and fall, thereby adjusting the position of the upper roller frame 23, so as to facilitate the pressing of different metal blanks.

[0024] Further, reference can be made to Figure 1 and Figure 7, the guiding structure 5 includes a guiding seat 56 installed on the top seat 13 and the bottom seat 11. A guiding roller 57 is rotatably installed inside the guiding seat 56. The guiding seat 56 is installed on the top seat 13 and the bottom seat 11 through an adjusting mechanism. The adjusting mechanism includes a guiding motor 51 fixed on the bottom seat 11 and the top seat 13, and a guiding screw rod 54 rotatably installed inside the bottom seat 11 and the top seat 13 through bearings. A guiding nut 55 is sleeved outside the guiding screw rod 54. The guiding seat 56 is fixed on the guiding nut 55. One end of the guiding screw rod 54 is fixedly installed with a driving worm gear 52. A driving worm 53 is engaged with one side of the driving worm gear 52. One end of the driving worm 53 is fixedly connected with the output shaft of the guiding motor 51. According to the width of the metal blank, the guiding motor 51 drives the driving worm gear 52 to rotate through the driving worm 53. The driving worm gear 52 drives the guiding screw rod 54 to rotate. The guiding screw rod 54 drives the guiding nut 55 and the guiding seat 56 to move, facilitating the guiding of the metal blank by the guiding roller 57. A guiding support seat 58 is fixedly installed inside the guiding seat 56. The guiding roller 57 is rotatably installed at both ends of the guiding support seat 58. A guiding support roller 59 is rotatably installed inside the guiding support seat 58. According to the position of the metal blank, the height of the guiding support roller 59 is adjusted by sliding the position of the guiding support seat 58, facilitating the guiding support roller 59 to support the metal blank.

[0025] For the guiding structure 5 adopting the above technical solution, during use, the guiding motor 51 drives the guiding screw rod 54 to rotate and drives the guiding roller 57 to adjust its position, thus facilitating the guiding and limiting of metal blanks with different widths. And by adjusting the position of the guiding support roller 59, it is convenient to support and convey different metal blanks.

[0026] Working principle and usage process of the present invention: During use, it is installed at the usage position and connected to the support roller 27 through a driving device. The rotation of the support roller 27 drives the rotation of the working roller 28. When in use, according to the processing requirements of the metal blank, the lowering motor 31 is driven to rotate the lowering screw rod 33. The lowering screw rod 33 drives one end of the lowering rod 34 to move, and the other end of the lowering rod 34 pushes the lowering seat 35 to descend, thereby driving the connecting frame 22 and the upper roller frame 23 to descend, adjusting the distance between the two working rollers 28. Moreover, the position can be adjusted by sliding the lower roller frame 24 in the lower adjustment groove 26, and positioning is achieved through the engagement of the positioning protrusion 241 and the positioning groove 261. Then, the auxiliary block 262 is installed on one side of the lower roller frame 24 for positioning, thereby ensuring more stable installation of the lower roller frame 24. According to the width of the metal blank, the guiding motor 51 drives the transmission worm wheel 52 to rotate. The transmission worm wheel 52 drives the guiding screw rod 54 to rotate. The guiding screw rod 54 drives the guiding nut 55 and the guiding seat 56 to move, facilitating the guiding of the metal blank by the guiding roller 57. Moreover, according to the position of the metal blank, the height of the guiding supporting roller 59 is adjusted by sliding the position of the guiding supporting seat 58, facilitating the guiding supporting roller 59 to support the metal blank. When a failure occurs after long-term use, the fixing knob 49 can be rotated to drive the fixing screw rod 46 to rotate. The fixing screw rod 46 drives the fixing nut 44 and the limiting pressing frame 43 to move, so that one end of the limiting pressing frame 43 is removed from the limiting card slot 42. Then, the limiting rotating frame 41 can be rotated to a vertical state, and the mounting frame 21 can be withdrawn. At the same time, the connecting frame 22 slides out of the lowering seat 35, thereby withdrawing the pressing roller structure 2 from the guiding groove 15. During installation, the new pressing roller structure 2 is inserted into the guiding groove 15, and at the same time, the connecting frame 22 is inserted into the lowering seat 35, which is more convenient and fast during disassembly and assembly.
