Multi angle hydraulic cone rolling machine is a device used to roll sheet metal into a cone shape, and its angle adjustment is the key operation to ensure accurate rolling of the required cone workpiece. This product mainly drives various working components such as rollers through a hydraulic system to achieve the rolling process. The adjustment of angles involves collaborative operations in multiple aspects, including the position of the rollers, pressure distribution, etc. During the rolling process, different taper requirements correspond to different ways of adjusting the working parts.

1. Preparation work

Before adjusting the angle, it is necessary to inspect the hydraulic cone rolling machine, check whether the oil level of the hydraulic system is normal, whether the oil quality is clean, and whether there are any leaks in the hydraulic pipelines. For example, the oil level should be maintained within the specified range of the oil tank. If the oil level is too low, it may cause the hydraulic system to malfunction. At the same time, check whether the surface of each roller is smooth, whether there is wear or damage, and place the sheet to be rolled on the feeding platform to ensure that the material, thickness, and other parameters of the sheet meet the working range of the hydraulic cone rolling machine. Different sheet characteristics have a certain impact on the rolling angle, for example, thicker sheets require greater pressure during the rolling process.

2. Adjust the position of the roller

For hydraulic cone rolling machines, the relative position of the upper and lower rollers has a significant impact on the rolling angle. Usually, by adjusting the height of the upper roller, the bending degree of the sheet can be changed, thereby adjusting the taper. The adjustment of the height of the upper roller is achieved through a hydraulic cylinder. During operation, the control panel or related mechanical adjustment device is used to control the amount of hydraulic oil flowing into the upper roller hydraulic cylinder according to the required taper size, so as to raise or lower the upper roller to the appropriate position.

3. Pressure adjustment

The hydraulic cone rolling machine relies on hydraulic pressure to cause plastic deformation of the sheet metal and roll it into a cone shape. During the rolling process, different pressures are required at the base and tip of the cone to produce the correct taper. For example, when rolling a cone, adjusting it slowly according to the principle of "less force at the bottom of the cone and more force at the tip" can achieve pressure distribution in different parts by adjusting the pressure regulating valve in the hydraulic system. If the pressure is not adjusted properly, it may lead to uneven rolling of the sheet, inability to achieve the expected taper, or excessive deformation or even damage of the sheet.

4. Angle verification and correction

After initial adjustment of position and pressure, conduct a test paper. A small piece of waste material with the same material and thickness as the actual production can be selected for the test paper. After rolling is completed, use a measuring tool to measure the angle of the cone being rolled.

Based on the measurement results, further adjustments are made to the position and pressure parameters of the hydraulic cone rolling machine. If the measured taper is larger than expected, it may be necessary to increase the downward pressure of the upper roller or adjust the pressure distribution. Otherwise, the opposite operation should be performed. This process may need to be repeated until the angle of the rolled cone meets the accurate requirements.

Before starting the angle adjustment, it is necessary to clarify the required taper of the Multi angle hydraulic cone rolling machine, which usually refers to the rate of change in the diameter of the cone in the vertical direction. In actual production, the target taper is determined according to product design requirements and requires excellent taper to meet assembly or functional requirements. Clarifying this value is crucial for subsequent adjustment operations, as it is the target value for the entire adjustment process of the hydraulic cone rolling machine.
