Introduction

Roll grooving is a widely used method for joining pipes in various industrial applications. A manual roll grooving machine is essential in creating a groove around the pipe's circumference, ensuring that pipes can be joined securely using couplings. This article provides an in-depth understanding of how a manual roll grooving machine operates, highlighting its mechanism, operating procedure, and solutions offered by the Hongli Pipe Machinery company.

Mechanism of Manual Roll Grooving Machines

A manual roll grooving machine operates by creating precise grooves on pipe ends through pressure deformation. The primary components of this machine include:

• Rollers: These are the primary tools that press against the pipe to form a grove.
• Support Stand: Provides stability to the pipe during the grooving process.
• Adjustment Mechanism: Allows operators to set the desired groove depth and size.

The grooving process involves positioning a pipe between two rollers—a drive roller and an idler roller. As the rollers exert pressure on the rotating pipe, a groove is formed. Parameters such as pipe diameter, material thickness, and roller size determine the precision of the groove.

Procedure for Operating a Manual Roll Grooving Machine

1. Preparation: Select the appropriate roller set for the pipe diameter and material. Adjust the machine settings to meet specific groove requirements.
2. Positioning the Pipe: Secure the pipe on the support stand, ensuring precise alignment with the rollers.
3. Grooving: Begin the manual operation by rotating the handle, engaging the drive roller, and exerting consistent pressure to form the groove.
4. Inspection: After grooving, inspect the groove for conformity with specifications, ensuring correct dimensions and smoothness.

Typical groove specifications include a tolerance of ±0.2 mm for depth and width, ensuring proper fit and function in coupling systems.
