Unsafe operation of a guillotine cutter can be dangerous. How to avoid these risks?


A guillotine cutter is a machine that utilizes a reciprocating linear motion between two blades to shear metal sheets. It consists of a moving upper blade and a fixed lower blade, with an optimal blade gap set to apply shearing force to metal sheets of various thicknesses, resulting in the desired size separation of the sheets. After shearing, it is important to ensure that the sheared surface of the metal sheet meets the requirements of straightness and parallelism while minimizing sheet distortion. The worktable is equipped with material support balls to prevent scratching of the sheet during sliding. The backgauge is used for sheet positioning, and its position is adjusted by a motor. The pressure cylinder is employed to hold down the sheet during cutting to prevent it from moving. Safety guards are installed as protective devices to prevent occupational accidents. The return stroke is typically powered by nitrogen gas, providing high speed and low impact.

After understanding the working principle of the guillotine cutter, it is important to know how to operate it safely:

Before operation, wear tight-fitting protective clothing with fastened cuffs. The upper garment should not be loose, and it is prohibited to change clothes or wrap fabric around the body near the running machine to prevent entanglement and injury. Wear a safety helmet, and tuck long hair inside the hat. Avoid wearing skirts or sandals.

Operators should be familiar with the main structure, performance, and operating methods of the guillotine cutter. It is a type of forging machinery primarily used in the metal processing industry. The product finds wide applications in various industries such as light industry, metallurgy, chemical, construction, shipbuilding, automotive, power, electrical appliances, and decoration, providing the required machinery and complete sets of equipment.

Here are the instructions for operating a guillotine cutter:

  1. Before starting the machine, perform blade alignment and adjust the material stop device. After performing 2-3 blank cuts, you can proceed with the operation.
  2. The blade gap should be determined based on the thickness of the steel plate and should not exceed 1/30 of the plate thickness.
  3. Ensure that the materials to be cut meet the requirements and do not exceed the specified limits. Prohibit cutting of bar stock, hardened materials, and materials with higher performance.
  4. It is not allowed to simultaneously cut two different materials on one guillotine cutter, and no one should stand behind it for material handling. When feeding the material, keep fingers at least 20 centimeters away from the cutting area, and use tools for handling small pieces.
  5. Maintain focus during operation and regularly check if the screws of the guillotine cutter are loose.
  6. Do not place tools, workpieces, or any other items on the bed surface. Clear the cut iron scraps promptly.
  7. When working with two or more people, coordinate and synchronize your actions, and assign a designated person to control the cutting switch.
  8. It is prohibited to cut stacked billets.
  9. After completing the work, turn off the power and lock the switch box.
  10. Assign a dedicated person to manage and perform regular maintenance on the guillotine cutter.
