Description

Technical Field

[0001] The utility model relates to the technical field of clamping equipment for material cutters, in particular to an eccentric clamping piece for material cutters. Background Art

[0002] At present, instrument vehicles, sawing machines or semi-automatic cutting equipment are usually used to cut pipes or bars. This type of cutting machine has a structure that uses a crank mechanism to make the movable blade (cutting blade) reciprocate in the up and down directions to cut the waste material between the fixed blade; or a cutting blade is directly installed at the lower end of the connecting rod connected to the crank shaft, and a pin guide is performed in the vertical direction near the cutting part.

[0003] The eccentric clamping mechanism clamps the workpiece by gradually increasing the radius of the eccentric wheel when it rotates. The mechanism that directly or indirectly clamps the workpiece with an eccentric is called an eccentric clamping mechanism. The commonly used eccentrics are eccentric wheels and eccentric shafts. The mechanism that directly or indirectly clamps the workpiece with an eccentric is called an eccentric clamping mechanism. There are two types of eccentrics: circular eccentric and curved eccentric. Circular eccentric has the advantages of simple structure, convenient operation, and rapid clamping, but it also has some disadvantages, such as small clamping force and clamping stroke, and poor structural impact resistance. Therefore, it is generally used in occasions with short clamping strokes and small and stable cutting loads.

[0004] This case was created to solve the above problems. Utility Model Content
