Embodiment Construction

[0037] The present invention will be further described below in conjunction with accompanying drawing.

[0038] Such as figure 1 As shown, a sawing equipment for heavy and large structural parts includes a frame 1, a guide column 2, a three-wheel sawing mechanism, a feed hydraulic cylinder 5, a machine base 16, a workbench, a guide correction mechanism, a workbench, and a clamping mechanism. components and controllers. The frame 1 is fixed on the machine base 16 . Two guide columns 2 are all fixed on the frame 1 and the support 16. The three-wheel sawing mechanism includes a saw frame 3 , a driving band saw wheel 4 , a saw band 6 , an intermediate band saw wheel 7 and a driven band saw wheel 8 . The saw frame 3 and the two guide columns 2 form a sliding pair. The two feeding hydraulic cylinders 5 are centrally arranged on the machine base 16 . Feed hydraulic oil cylinder 5 adopts double rod oil cylinder. The two ends of the piston rod on the feeding hydraulic oil cylinde...

Abstract

The invention discloses a heavy and extra-large structural member saw-cutting device and a saw-cutting method thereof. A two-wheel type sawing machine for saw-cutting a large structural member requires the matching of large-dimensional saw belt wheels, so that the production cost is greatly improved. The invention relates to the heavy and extra-large structural member saw-cutting device which comprises a rack, a three-wheel saw-cutting mechanism, a feeding hydraulic oil cylinder, a working table, a guiding and correcting mechanism, a workbench and a clamping assembly. The three-wheel saw-cutting mechanism comprises a saw frame, a driving belt saw wheel, a saw belt, a middle saw belt wheel and a driven saw belt wheel. The guiding and correcting mechanism comprises a guiding block, a correcting movement plate, a correcting swinging worm, a correcting swinging worm wheel, a correcting drive piece and a torsion motor. The working table comprises a swinging table, a moving table, a transverse movement drive piece, a swinging spring and a swinging air cylinder. According to the heavy and extra-large structural member saw-cutting device and the saw-cutting method thereof provided by the invention, a traditional two-saw-belt-wheel transmission structure is changed into a three-saw-belt-wheel transmission structure, so that the defect that the conventional two-saw-belt-wheel sawing machine requires the diameter of each saw belt wheel to be larger than the diameter of a workpiece is overcome, and the volume and the height of the whole machine are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of intelligent manufacturing, and in particular relates to a large-scale numerical control sawing equipment and a sawing method for processing heavy and extra-large structural parts. Background technique [0002] At major engineering sites, many large structural parts need to be cut and processed during welding and installation. At present, there is a lack of on-site sawing and processing equipment, and traditional methods such as gas cutting and manual cutting are often used. Therefore, there are low cutting accuracy, large material waste, and cutting efficiency. Low main problem. How to reduce material waste, improve cutting accuracy and efficiency at major engineering sites? It is the development direction that the sawing processing industry has been striving for. Therefore, it is urgent to provide a large-scale numerical control band saw cutting equipment used in major engineering sites. [0003] In r...
