Three-roller differential variable-curvature numerical control plate rolling machine

Abstract

The invention relates to the technical field of plate bending machines, in particular to a three-roller differential variable-curvature numerical control plate bending machine which comprises a plate bending machine body, a left supporting seat is fixedly connected to the position, close to the left side, in the plate bending machine body, and a right supporting seat is fixedly connected to the outer surface of the right end of the plate bending machine body. A turnover support is arranged on the outer surface of the upper end of the right supporting seat, a first bearing is connected to the outer surface of the left side of the right supporting seat in an embedded mode, a limiting block is fixedly connected to the position, corresponding to the first bearing, of the outer surface of the left side of the right supporting seat, an upper roller is arranged on the inner surface of the turnover support, and a lower roller is arranged below the upper roller. According to the structure of the device, metal workpieces of different shapes and sizes can be automatically unloaded, metal scraps and dust in the machining process can be cleaned and collected, cleanliness of the whole device is guaranteed, damage of the metal scraps to parts is reduced, the working efficiency is greatly improved, and the labor intensity of a user is reduced.

Description

technical field [0001] The invention relates to the technical field of plate rolling machines, in particular to a three-roller differential speed variable curvature numerical control plate rolling machine. Background technique [0002] Three-roll plate rolling machine has mechanical type and hydraulic type: Mechanical three-roll plate rolling machine is divided into symmetrical and asymmetrical. It can roll metal sheets into circular, arc and conical workpieces within a certain range. Its working principle is that the upper roller moves vertically at the symmetrical position in the center of the two lower rollers. For rotary motion, driven by the motor. The output gear of the reducer meshes with the gear of the lower roller to provide torque for the rolled plate, so that the metal plate undergoes continuous bending for multiple passes, resulting in permanent plastic deformation, and rolled into the required cylinder, cone or their shape. Part of it is widely used in indust...

Problems solved by technology

The utility model can make the device achieve the function of high degree of automation through the hydraulic oil cylinder, the material receiving table, the driving frame, the adjustable strong strut, the movable shaft, the movable wheel, the screw rod, the second motor, the screw block and the rubber pad, and solves the problem of The unloading device of the plate rolling machine on the existing market does not have the function of high degree of automation. It takes time and effort for the staff to unload the material, and the unloading and handling of large pipe fittings is inconvenient, which affects the work efficiency and has the problem of safety hazard.

[0004] 1. In the above comparative patent, the automatic unloading of metal workpieces can be realized by setting an automatic unloading device above the plate rolling machine, but this device can only unload cylindrical metal workpieces. For conical or arc-shaped workpieces, it is also impossible to hang the metal workpiece on the fixed frame for automatic unloading, and when the plate bending machine bends the metal plate, it is easy to generate a large amount of metal debris, which falls on the plate bending machine and affects the The plate rolling machine is clean. If metal debris falls inside the parts, it is easy to cause damage to the parts. It needs to be cleaned by the user in time, which increases the labor intensity of the user. The overall needs to be improved
