Description

Technical Field

[0001] The utility model relates to the technical field of cutting saws, in particular to a cutting and pressing mechanism of an interrupted saw. Background Art

[0002] Profiles are objects with certain geometric shapes made of iron or steel and materials with certain strength and toughness through rolling, extrusion, casting and other processes. This type of material has a certain appearance size, a certain cross-section shape, and certain mechanical and physical properties. Profiles can be used alone or further processed into other manufactured products, and are often used in building structures and manufacturing and installation. Mechanical engineers can select the specific shape, material, heat treatment state, mechanical properties and other parameters of the profile according to the design requirements, and then divide the profile according to the specific size and shape requirements, and then further process or heat treat it to achieve the design accuracy requirements. The material, specifications and dimensions of the profile can refer to the corresponding national standards. In the process of dividing the profile, an automatic interruption saw is required. The automatic interruption saw is an automated equipment that can achieve the profile cutting effect.

[0003] When the interrupted saw cuts the profile, a pressing mechanism needs to be set to press the profile to ensure that the profile remains stable during the cutting process and improve the cutting accuracy. The existing pressing equipment has a short height adjustment distance in a limited space and has poor use effect. Utility Model Content
