Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a forming device and method for thinning and cutting grooves on the front side of a plate without a track, so as to solve the problem that the thinning of the plate can only be performed on the reverse side and the cutting groove can only be performed on the back side and the technology of manual adjustment of the track leads to no guarantee of accuracy problem

Embodiment

[0032] Figure 7 Middle steel plate 34 is 20mm thick, and steel plate 36 is 55mm thick, and steel plate 34 is spliced ​​with steel plate 36, and thinning will be decided according to the thickness of steel plate 34. Steel plate 36 tops cut off 20mm, and bottom cuts off 15mm. Cutting work sequence, or cut the thinning surface 35 first, then cut the thinning surface 37, and then process the welding groove 38; or first cut the thinning surface 37, then cut the thinning surface 35, and then process the welding groove 38. The thinning slope of the thinning surface 35 and the thinning surface 37, that is, the vertical length: the horizontal length is 1:4 (or 1:5), and the welding groove 38 adopts different welding methods and different angles, which is 27.5 in this example. 0 . According to the above type, adjust the cutting torch to the angle of thinning or cutting the groove according to the steps of the method of thinning the steel plate without turning over and cutting the wel...

Abstract

A machine for thinning, cutting and welding the bevel surface of steel plate without turnover the steel plate is composed of a semi-automatic flame cutting machine, its walk guiding mechanism with Z-shaped connecting rod and guide wheel as lower end of said Z-shaped connecting rod, a cutting torch rotatnig and fixing mechanism, and the brackets for bearing plates on which the carriage and cutting machine can run.

Description

(1) Technical field [0001] The invention relates to a forming technology for front thinning of steel plates and cutting welding grooves, in particular to a device and method for trackless front thinning and groove cutting of ultra-thick plates and curved edge plates. (2) Background technology [0002] Over the years, in the shipbuilding field and non-ship product manufacturing process, the thinning of thick plates in plate splicing has been using reverse forming technology. Using this forming method, the operator will lean over and look up at the thinning position line while controlling the cutting machine on the plate during cutting. Like this, while increasing labor intensity, also restricted cutting quality. If the front side is thinned and formed, the closer to the edge plate end, the lower the flame temperature at the edge, resulting in serious quality defects such as undercut, lack of meat, and hanging slag. In addition, in the past, semi-automatic cutting machine gu...
