How To Flatten The Sandwich Panel Machine

As an important equipment for metal sheet processing, the levelness of sandwich panel machines directly affects the processing quality and equipment service life.

Before starting to level, sufficient preparation work must be done:

• Environmental inspection: Choose a stable installation location without strong vibration interference to ensure that the ground load-bearing capacity is sufficient to support the weight of the equipment. For large sandwich panel machines, it is recommended to use concrete foundations.
  

• Tool preparation: Precision frame level (accuracy ≥ 0.02mm/m), height block, feeler gauge, torque wrench, hex wrench, cleaning cloth and other tools need to be prepared. The level is the most critical measuring tool in the leveling process.
  

• Cleaning treatment: Thoroughly clean the bottom surface of the equipment and the installation reference surface, remove rust proof oil and impurities with anhydrous alcohol, and ensure that there are no foreign objects affecting the leveling accuracy of the contact surface.

Leveling method and steps

• Use leveling bolts (suitable for small equipment)
  Most sandwich panel machine bases are designed with leveling bolts, which are the most commonly used leveling method:
  Place the machine in the designated position, preliminarily fix but not fully lock it
  Place a level on the machine workbench and observe the position of bubbles
  Rotate the leveling bolt gradually in diagonal order, with a small adjustment amplitude each time
  Prioritize adjusting the vertical direction (longer direction) before adjusting the horizontal direction
  Repeatedly check until all bubbles are accurately centered in all directions

• Use shims or thin plates to level
  For equipment without leveling bolts, the gasket leveling method can be used:
  Use a spirit level to determine the direction and degree of machine tilt
  Gradually add metal gaskets (stainless steel or galvanized steel sheet) under the low side base
  Recheck the levelness after each addition
  The gasket should be flat and free of burrs, with an area not less than the contact surface of the base
  Ensure that all contact points are uniformly stressed in the end

• Use adjustable foot pads (suitable for large equipment)
  Heavy sandwich panel machines are often equipped with adjustable foot pads:
  Loosen the locking nut of the foot pad
  Rotate the adjusting nut to change the height
  Adopting the principle of "three-point support": fix one reference corner point and adjust the other two points
  After adjustment, tighten all nuts to prevent loosening during use

Precision leveling techniques

• Multi point measurement method: Select multiple points (corners and center) evenly on the workbench and place a level to comprehensively detect flatness. Fine adjust according to the reading to ensure that the entire working surface is flat.
  

• Diagonal review: Place the level along two diagonal directions for inspection. If there is a deviation, it is necessary to make slight collaborative adjustments to the adjustable points until the bubbles are accurately centered in all directions.
  

• Temperature control: Leveling should be carried out when the ambient temperature is stable to avoid the influence of thermal deformation. After running for a period of time, the levelness of the equipment should be rechecked.

Final fastening and verification

• After completing the preliminary leveling:
  

• Gradually and evenly increase the torque of the installation bolts to the specified value in 2-3 steps in diagonal order
  

• Use a torque wrench to ensure consistent tightening accuracy
  

• After all bolts are tightened, reposition the level in all key directions for retesting
  

• The fastening process may cause slight deformation, and final adjustments should be made based on the retest results

Precautions for use

• Regularly check the levelness of the equipment, and it is recommended to conduct a re inspection every 3 months or after 500 hours of production
  

• The device must be re leveled after moving or being subjected to significant impact
  

• Avoid using lubricants on leveling bolts or foot pads to prevent loosening
  

• After leveling, a trial run should be conducted to check for any abnormal vibrations

Common problem solving

• Still unstable after leveling: Check the ground's load-bearing capacity and may require reinforcement of the foundation
  

• The bolt cannot be tightened: it may be due to thread damage, and the leveling bolt component needs to be replaced
  

• Large horizontal variation: Check whether the equipment frame is deformed or welded with cracks

By using the above professional leveling methods, it is possible to ensure that the sandwich panel machine reaches its optimal working state, improve product quality, and extend equipment service life. For special models of equipment, it is recommended to refer to the specific leveling manual provided by the manufacturer for operation.
