Detailed Description

In order to make the purpose, technical solution and advantages of the present technical solution more clear, the present technical solution is further described in detail below with reference to specific embodiments. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present teachings.

Example 1

As shown in fig. 1 to 4, the steel plate cutting apparatus for cutting a steel plate 70 to be cut in a straight line according to the present embodiment includes a table 10, a portable rail 20, an electric driving vehicle 30, a flame head support frame 31, a flame cutting head 32, a pipe clamp assembly 41, a support rod assembly 42, a smoke abatement recovery pipe 50 and a negative pressure pipe 60, wherein the steel plate 70 to be cut is placed on the table 10, a position to be cut of the steel plate 70 extends out of the table 10, the portable rail 20 is placed on a top surface of the steel plate, the electric driving vehicle 30 is movably mounted on the portable rail 20, and the flame cutting head 32 is mounted on the electric driving vehicle 30 through the flame head support frame 31; the pipe clamp assembly 41 is adjustably arranged on the flame head support frame 31, the support rod assembly 42 is adjustably arranged on the flame head support frame 31, and the smoke abatement recovery pipe fitting 50 is arranged at the lower tail end of the support rod assembly 42;

as shown in fig. 2, the moving direction of the electric driving cart 30 is towards the right side of fig. 2, in the horizontal plane, the electric driving cart 30 moves linearly along the X direction, the pipe clamp assembly 41 and the supporting rod assembly 42 bypass the side of the steel plate 70 to be cut along the Y direction, and the Y direction is perpendicular to the X direction, so that the smoke-removing recovery pipe fitting 50 is arranged below the flame cutting head 32, the smoke-removing recovery pipe fitting 50 has a smoke suction inlet, the smoke-removing recovery pipe fitting 50 avoids the flame direction of the flame cutting head 32, and the smoke suction inlet faces the extension line of the flame direction of the flame cutting head 32.

As shown in fig. 2, the electric drive vehicle 30 moves in the right direction in fig. 2, the flame cutting head 32 is inclined toward the rear of the movement direction of the electric drive vehicle 30, and the inclination angle of the flame cutting head 32 is greater than 15 ° and less than 30 °. In use, it has been found that when the torch cutting head 32 is oriented as shown in FIG. 2, the swarf produced by the torch cutting does not splash and the fumes are more concentrated.

Referring to fig. 3 and 4, the smoke abatement recycling pipe 50 is a circular pipe 51, the circular pipe 51 has an annular opening inside, the annular opening is a smoke suction inlet, and the extension line of the flame direction of the flame cutting head 32 is located in a hollow area enclosed by the circular pipe 51.
