The structure and working system of the expanding machine
Organizational composition; This machine consists of a base, a gantry, an expansion unit, a lifting system, a moving system, etc.
Expander working system:
The lifting motion of the expanding head is completed by the electric motor driving the turbine worm elevator
Forward and backward movement of the expanding head: When the end of the steel pipe reaches the expanding die head, the contact between the expanding die and the steel pipe section is fine tuned by the forward and backward movement of the moving oil cylinder to avoid long-term collision of the steel pipe with the working disc of the equipment, which may cause equipment damage.
The expanding motion of the expanding head is achieved by pulling the multi sided cone through the main oil cylinder, and the movement of the multi sided cone drives the inclined block connected to the expanding head mold to move outward in the circumferential direction, thereby achieving the expanding motion.
Installation of Expanding Machine Equipment
The equipment must be installed on a solid concrete foundation and secured with anchor bolts. The foundation of the machine is constructed according to the foundation drawing. Install using the secondary pouring method and place a level on the workbench for vertical and horizontal correction, allowing for
The difference is 0.15/1000 millimeters.
1. Equipment adjustment
After installing the equipment on a solid concrete foundation, tighten the surrounding anchor bolts before testing and recheck the installation
Horizontal plane; All parts of the machine need to be thoroughly inspected; Each sliding surface should be lubricated according to the requirements of the user manual
grease
2. Hydraulic system inspection:
Check whether the connections of various hydraulic systems, such as pumps, valves, and oil pipe joints, are tight and free of oil leakage.
Maintenance and upkeep of the expanding machine:
In addition to daily maintenance, machines also require regular maintenance. For example, the factory implements a single shift system, which means conducting a thorough inspection and maintenance once a day. The content includes checking the grounding and insulation of the motor and circuit, and checking the fasteners
Check for looseness and damage, whether the lubrication system's oil circuit is unobstructed, whether the temperature of the hydraulic oil tank is normal, and promptly clean the debris on each workbench of the equipment. If any problems are found, repair them in a timely manner.
