Embodiment 1

[0032] see now figure 1 and figure 2 , figure 1 It is a structural schematic diagram of a stress hole cutting machine for stiffened plates according to an embodiment of the present invention, figure 2 for figure 1 side view. As shown in the figure, the center of the base 1 is vertically provided with a vertical pole; a peripheral edge of the base 1 is fixedly connected to a rectangular steel plate operating platform 10 with a gap, and the middle part of the operating platform is provided with a long strip with a semicircular head. , A zone and B zone are set up on both sides of the semicircular head;

[0033] The two ends of the pole 3 are provided with sleeves, one end of which is sleeved on the pole, and is fastened on the pole by the first adjusting bolt 2, and the pole 3 is perpendicular to the pole; the pole 3 Can move up and down on the pole to adjust the height.

[0034] The rotating shaft 5 is fitted in the sleeve at the other end of the pole 3, the upper part ...

Embodiment 2

[0037] A method for using a stress hole cutting tool in a stiff plate, characterized in that it comprises the following steps:

[0038] a. Put the stiff plate stress hole cutting machine on a platform with a certain height from the ground, fix the air supply device and the cutting nozzle on the branch pipe 6 for installing the air supply device and the branch pipe 7 for installing the cutting nozzle respectively, and then The A area and the B area of ​​the operating platform 10 each place a stiff plate with a stress hole to be processed; the first dividing plate 91 and the second dividing plate 92 are arranged on both sides of the semicircular notch, and the first dividing plate 91 and the second dividing plate 92 Arranged in a straight line, the third partition 93 is set on the boundary line between the A area and the B area, and is perpendicular to the line connecting the first partition 91 and the second partition 92, so as to ensure that the stiffeners are placed vertically...

Abstract

A machine tool for cutting stress holes in stiff plates, comprising a base (1), a support rod (3), a rotating shaft (5) and a partition (9), characterized in that: the center of the base (1) is vertically provided with a vertical rod; A peripheral edge of the base (1) is fixedly connected to a rectangular steel plate operating platform (10) with a notch, sleeves are provided at both ends of the pole (3), and the rotating shaft (5) is sleeved on the pole (3). ), the partition (9) includes a first partition (91), a second partition (92) and a third partition (93). The stiffened plate stress hole cutting machine tool and usage method of the present invention have the advantages of simple machine tool structure, convenient manufacture, fast mechanical cutting speed, stable and excellent cutting quality, greatly reduced labor intensity of workers, improved work efficiency and reduced engineering cost.

Description

technical field [0001] The invention relates to a flame cutting machine tool, in particular to a stiff plate stress hole cutting machine tool and a usage method. Background technique [0002] During the processing of steel structural members, the processing of H-shaped steel columns and steel beams is often encountered. Designers usually add stiffeners to the webs of H-shaped members to strengthen the strength of the members, and add stiffeners on both sides of the stiffeners. Stress holes are added at the end to eliminate the internal stress of welding. [0003] In general, during production and processing, workers use a flame cutter to manually open stress holes in the stiffener when assembling the stiffener. But the stress hole made in this way is not only of poor quality, but also the size of the stress hole radius R is not easy to control during operation. At the same time, this method has low work efficiency and affects the progress of the project. [0004] Therefore...
