Product Description

CNC horizontal downward plate rolling machine is a hydraulic three-roll plate rolling machine, which is used to roll steel plates into cylindrical shapes at room temperature.

The upper roll can move vertically and the lower roll can move horizontally.

Pre-bending is achieved by moving the lower roll horizontally so that the upper roll is asymmetrically positioned relative to the lower roll.

The two lower rollers are driven by two motors and two reducers during rounding.

Since the elevation of the lower roll remains unchanged, it is convenient for feeding and operation.

Computer program control and monitoring system.

Product Features：

Three rolls CNC horizontal downward rolling machine is a hydraulic numerical control type, mainly composed of an upper roll device, lower roll device, bed, left frame, right frame, horizontal moving device, idler device, inverted frame, balancing device, main drive assembly, oil cylinder, hydraulic system, PLC control, etc.

The upper roll device is composed of the upper roll, the upper roll bearing pedestal, the self-aligning bearing for the rolling mill, etc.

The upper roll is in a drum shape. In design, the load coefficient of the maximum applied pressure of the upper roll is 0.7, and the uniformly distributed load is preset to compensate for the deformation deflection of the upper roll.

The upper roll is made of 42CrMo, quenched and tempered after rough machining, HB240~280, and surface quenched after finish machining, HRC45-55.

The lower roll device is composed of the lower roll, the lower roll bearing pedestal, the self-aligning bearing for the lower roll mill, etc.

The material of the lower roll is 45 #, which is quenched and tempered after rough machining, HB240~280, and the surface is quenched after finishing machining, HRC45-55.

The idler device is composed of the idler, aligning bearing, bearing seat, etc.

The overturning device is composed of an overturning frame, a support, a pin shaft, an oil cylinder, etc. The overturning device is small in size, safe and small in floor area when overturning.

The balancing device consists of a support and a pull rod. After the rack on the overturned side is overturned, the balancing device presses the tail of the upper roll to keep the balance of the upper roll.
