Description

Technical Field

[0002] The front positioning of a plate shearing machine is an indispensable and important part of the plate shearing machine, and is an important component related to the positioning accuracy of the size of the sheet material when shearing the sheet material by the front positioning method. The existing front positioning of the plate shearing machine has the following deficiencies:

[0003] 1) In terms of the design of the front positioning structure: The existing front positioning of the plate shearing machine uses the method of adding T-shaped grooves on the material supporting frame, installing movable stoppers, and locking and fixing with screws after manually adjusting the position. This structure is relatively simple, troublesome in manual adjustment, low in efficiency, and not highly utilized in actual use.

[0004] 2) In terms of the positioning stroke: Since the positioning stopper is installed on the front material supporting frame, and the front end of the front material supporting frame is far from the position of the lower blade, the position of the positioning stopper is also far from the lower blade, which cannot meet the front positioning shearing of some narrow sheet materials.

[0005] 3) In terms of the use of positioning shearing: Since the positioning stopper is locked and fixed with screws after manually adjusting the size position, when continuously shearing sheet materials of different sizes, the front positioning function cannot meet the normal use in this case.

[0006] 4) In terms of the positioning accuracy: Due to the large error in manual adjustment of the positioning stopper, the positioning dimension accuracy is poor, which cannot meet the requirements for high-precision sheet material sizes in the development of the sheet metal industry.
