Problems solved by technology
The section quality of the section steel cut by manual flame is poor, and there is a heat-affected zone in the section steel after cutting, which needs to be polished to remove the heat-affected zone. This process cannot be used for blanking of welded parts with high quality requirements; although the existing mechanical cutting process can overcome The shortcomings of the process, but the work efficiency is low and the cost is high, which is not conducive to mass production

Embodiment Construction
[0025] Below in conjunction with accompanying drawing, the present invention is described in detail.
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0027] Such as figure 1 Shown is a schematic diagram of the structure of the hat-shaped steel, and this embodiment takes cutting the hat-shaped steel as an example.
[0028] Such as Figure 2-5 As shown, a stamping die for cutting section steel includes an upper mold composition and a lower mold composition, and the upper mold composition includes an upper template 1 and a punch connected to the upper template 1 for cutting section steel 4. The shaped steel is a hat-shaped steel, and the lower ...

The invention discloses a stamping mold used for cutting section steel, which comprises an upper mold component and a lower mold component, wherein the upper mold component comprises an upper mold plate and a male mould component connected with the upper mold plate and used for cutting section steel; the lower mold component comprises a lower mold plate and two groups of female mold components arranged symmetrically connected with the lower mold plate; a gap is formed between the two groups of female mold components; an adjustable positioning baffle component and a feeding bracket component are arranged outside the upper and the lower groups of female mold components of the lower mold plate; and the upper mold plate and the lower mold plate are in slidable connection through a guide pole. Blanking process is adopted for cutting section materials such as hat type section steel, channel steel and the like, and the section steel is quickly cut through matching between cut male molds and cut female molds, so that the problems existing in the processing technology of manual flame cutting and mechanical cutting are efficiently solved; and the stamping mold has the characteristics of being high in production efficiency, low in production cost and good in cross section quality.
Description
technical field [0001] The invention relates to a stamping die for cutting section steel. Background technique [0002] At present, the cutting of hat-shaped steel and channel steel usually adopts manual flame cutting or mechanical cutting process. The section quality of the section steel cut by manual flame is poor, and there is a heat-affected zone in the section steel after cutting, which needs to be polished to remove the heat-affected zone. This process cannot be used for blanking of welded parts with high quality requirements; although the existing mechanical cutting process can overcome The shortcomings of the process, but the work efficiency is low and the cost is high, which is not conducive to mass production. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems and provide a stamping die with high cutting speed and high cutting section quality, which is mainly used in the cutting process of hat-shaped s...
