Problems solved by technology

With manual plasma cutting, the cutting track cannot be guaranteed; with robotic cutting, because the head is too large and the length of the robotic arm is limited, the cutting cannot be completed at one time. Therefore, the head needs to be rotated for secondary positioning, or even three positioning for cutting. Multiple positioning is also necessary. It will cause unstable cutting trajectory, long working time, low production efficiency, and prone to waste products

Embodiment Construction

[0025] exist Figure 1 to Figure 8 In the schematic diagram of the present invention, the eight-sided arc-shaped head cutting process of the railway intermodal vehicle tank container of the present invention is as follows:

[0026] Step 1. Manufacture the shape-cutting support frame of the head manipulator: the shape-cutting support frame is composed of support frame legs 1 , forming positioning files 2 and support frame panels 3 . The lower part of the support frame panel is provided with support frame legs, the forming positioning block is set on the support frame panel, and the inner surface of the forming positioning block is the same as the arc of the head;

[0027] Step 2. Fit the curved surface of the head and the curved surface of the shape positioning: in order to avoid scratches on the stainless steel, use the crane, use the non-marking pliers, and the head of the elevator, and place it on the cutting support frame steadily and slowly, and inspect the head The arc s...

Abstract

The invention provides a shape cutting process for an octahedral arc-shaped sealing head of a tank container of a railroad through transport vehicle. The shape cutting process comprises the followingsteps: (1) manufacturing a shape cutting support frame for a sealing head manipulator; (2) adhering a sealing head arc surface and a shape positioning arc surface; (3) drawing running track positionsof the manipulator; (4) programming and cutting; (5) shielding a nonworking region; (6) cutting; (7) grinding; and (8) measuring the dimensions. The shape cutting process provided by the invention canguarantee that the sealing head stops moving after the sealing head is positioned once; after numerical control programming of a cutter, a cutting gun stably runs according to a preset track, so quality errors caused by multi-time positioning are prevented, and the sealing head is guaranteed to be absolutely qualified. The shape cutting process guarantees stable shape cutting quality, zero rejection rate and relatively high universality.

Description

technical field [0001] The invention belongs to the technical field of shape cutting technology, and in particular relates to a shape cutting technology of eight-sided arc-shaped head of a tank container of a railway intermodal vehicle. Background technique [0002] At present, the cutting shape of the eight-sided arc-shaped head of the tank container of the railway intermodal vehicle adopts various machine tools to rotate the head, and the technological idea of ​​​​not moving the tool is used for cold cutting. Due to the irregular shape of the eight-sided arc-shaped head, it cannot be processed by machine tools, and can only be processed by plasma cutting. With manual plasma cutting, the cutting track cannot be guaranteed; with robotic cutting, because the head is too large and the length of the robotic arm is limited, the cutting cannot be completed at one time. Therefore, the head needs to be rotated for secondary positioning, or even three positioning for cutting. Multip...
