Description
Technical Field
[0001] The utility model relates to the technical field of PMI foam production, in particular to a cutting device for PMI foam production. Background Art
[0002] PMI foam is a foam plastic with the highest specific strength and specific modulus. Using PMI foam to make composite sandwich structures can significantly improve strength, rigidity, weight, avoid instability, and improve the energy efficiency of aircraft. In the production process of PMI foam, due to different uses, the specifications of PMI foam required are also different, so it is necessary to use a cutting device to cut PMI foam. For example, a foam plastic board cutting device for foam plastic production described in the patent announcement number CN216682488U solves the problem that when cutting foam plastic boards, the cut waste is easily scattered, making it inconvenient to collect.
[0003] However, the device is not convenient for clamping and positioning plastic foams of different widths and thicknesses, which makes the plastic foam prone to shaking during the cutting process, thereby reducing the accuracy of the cutting work and making the plastic foam extremely easy to be damaged after cutting errors, thereby increasing the cost of the cutting work. At the same time, saw blade cutting is different from laser cutting. Saw blade cutting will produce some toxic fumes due to the friction of foam plastics due to the high temperature, thus affecting the health of the operator.
[0004] Based on this, a cutting device for PMI foam production is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content
