Description

Technical Field

[0001] The utility model relates to the field of cutting machines, and particularly to an electric flat cutting machine with higher energy efficiency. Background Art

[0002] A flat cutting machine is a mechanical device used for cutting various flat materials, and is widely used in the processing industries of various materials such as leather, fabric, rubber, plastic, paper, foam, sponge, composite materials, etc. A flat cutting machine is a device that cuts materials by the closing of upper and lower cutting dies. According to different power sources and cutting methods, flat cutting machines can be divided into various types, such as electric flat cutting machines, pneumatic flat cutting machines, hydraulic flat cutting machines, etc. Pneumatic flat cutting machine: uses compressed air as the power source, has the advantages of environmental protection, energy saving, easy maintenance, etc., and is suitable for small and medium-sized enterprises and small batch production. Hydraulic flat cutting machine: uses hydraulic oil to transmit power, has the characteristics of large cutting force and high cutting accuracy, and is suitable for cutting large and thick materials.

[0003] Although the hydraulic flat cutting machine has the advantages of large cutting force and high cutting accuracy, it also has some disadvantages in the use process, such as easy leakage of oil and possible environmental pollution, and the viscosity of the hydraulic oil is affected by temperature; the hydraulic transmission efficiency is low, and the energy efficiency ratio is low during use, and it cannot achieve a good energy-saving effect; high requirements for hydraulic components, difficult to detect fault symptoms, and hydraulic is not suitable for long-distance transmission, making the cost of the hydraulic flat cutting machine high and very power-consuming.

[0004] There are also electric flat cutting machines in the market, but their accuracy is not high: although electric flat cutting machines can provide stable cutting effects in most cases, in occasions with extremely high accuracy requirements, such as precision machining or cutting of special materials, it may be difficult to achieve the ideal accuracy. This may affect product quality and subsequent processing; the structure of electric flat cutting machines in the market is complex, and the maintenance and repair costs are high; in addition, electric flat cutting machines in the market will generate relatively large noise and vibration during operation, which may have an adverse impact on the working environment and operators.
