Forming rolling machine

Abstract

The invention provides a forming rolling machine which comprises a rack. A downward-pressing adjusting device is arranged on the upper portion of the rack and connected with a small motor, and a pressroll assembly is arranged on the lower portion of the downward-pressing adjusting device. A transmission system is arranged on the rack and provided with a winding roll, and two symmetrically-arranged press rolls in the press roll assembly are located over the winding roll. The transmission system is sequentially connected with a deceleration system assembly and a large motor orderly. According to the forming rolling machine, the distance between the winding roll and the press rolls can be adjusted according to the material thickness and the diameter of a tube body, and rolling is facilitated; the braking torque of the forming rolling machine is large, the service life of a friction plate is long, the heat-dissipating capability is high, starting is gentle, stopping is stable, and heat energy recovery is easy; and through operation and adjusting of a controller, connection is stably conducted, the braking performance is brought into full play, the structure is simple, thus long-term usage is achieved, and maintenance is easy.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a forming rolling machine. Background technique [0002] The traditional barrel rolling is made by using a three-roller rolling machine, and it is rolled directly. If there is a straight head, it needs to be pre-bent before rolling, and the rolling efficiency is low. After rolling, the opening is not uniform, and it needs to be reshaped and closed. [0003] The structure of the three-roller rolling machine is a three-roller symmetrical type. One upper roller moves vertically at the symmetrical position of the two lower rollers. The vertical lifting movement is realized through the screw, screw nut and worm drive, and the two lower rollers rotate. , driven by a motor. The output gear of the reducer meshes with the gear of the lower roll to provide torque for the coiled sheet. The disadvantage is that the end of the plate needs to be pre-bent with other equipment, and it is i...
