Problems solved by technology
However, when large blanks (greater than 250×250mm) are selected for billet stamping, due to the limitation of steel plant process conditions, large blanks are often diamond-shaped or irregular in shape, and the dimensions of their two diagonals are inconsistent, or even have large deviations. Make the punching billet wall thickness uneven
After the punching blank is drawn, the wall thickness of the obtained gas cylinder will also be uneven, which will affect the product quality

Embodiment Construction
[0014] As shown in the figure, a blank shaping machine for manufacturing steel seamless gas cylinders includes a frame 1. The frame 1 is composed of a square upper frame 11, a middle frame 12, a lower frame 13 and surrounding columns 14. Of course, the rack 1 can also be a whole, and such setting is only for saving materials. The centers of the upper frame 11 and the middle frame 12 are all provided with through holes, wherein the through holes of the upper frame 11 are discharge ports 7 . One side between the upper frame 11 and the middle frame 12 is used as the feed inlet 8, and the remaining 3 sides are respectively provided with a vertical guide plate 41 whose bottom end is fixed on the middle frame 12. The blank guide mechanism 4 that the shape of the blank 3 matches.
[0015] The top end of the billet guide mechanism 4 extends to the discharge port 7 provided on the upper frame 11, and the bottom end is fixed on the middle frame 12 as the load-bearing platform 5, and a ...

The invention discloses a blank shaper for manufacturing a steel seamless air bottle, which comprises a stander. One side of the stander is provided with a feed opening, the top of the stander is provided with a discharge opening, the interior of the stander is provided with a bearing platform communicated with the feed opening and an upright blank guiding mechanism of which the bottom end is fixed on the bearing platform, the top end of the blank guiding mechanism extends to the discharge opening, and the center of the bearing platform is provided with a hydraulic cylinder for pushing a blank to move along the blank guiding mechanism; the inside of the discharge opening is provided with four wheel shafts on the same horizontal plane, the wheel surfaces are provided with rollers with inner concave cambered surfaces, the wheel surfaces of two opposite rollers are mutually opposite and the distances of the wheel surfaces are equal; and when the blank is pushed out from the discharge opening, the four rollers extrude and process four ribs of the blank respectively. The spaces of the two opposite rollers at the top of the stander of the shaper are equal, the diagonal lines of the square blank can be equal through extrusion, simultaneously the circumferential surface of the roller is a concave arc surface, so the four corners of the blank are easily processed into the required arc angles, and the wall thickness of a punching blank is evener.
Description
technical field [0001] The invention relates to the field of manufacturing steel seamless gas cylinders, in particular to a blank shaping machine for manufacturing steel seamless gas cylinders. Background technique [0002] Existing high-pressure steel gas cylinders are mainly made by plate stamping, steel billet stamping, and steel pipe closing and bottoming. bottle. The blank used is generally square, and the dimensions of its two diagonals should be the same, so that the wall thickness of the punched blank and the cylinder is uniform. [0003] The small billet (less than 230×230mm) selected for billet stamping is generally cast by a steel factory, and its two diagonal dimensions are relatively consistent. However, when large blanks (greater than 250×250mm) are selected for billet stamping, due to the limitation of steel plant process conditions, large blanks are often diamond-shaped or irregular in shape, and the dimensions of their two diagonals are inconsistent, or ev...
