Detailed Description

As shown in fig. 1, the air storage tank comprises a cylindrical barrel 9, the barrel 9 is usually formed by bending a square steel plate, and the joints of the two ends of the steel plate are fixed by welding, and in fig. 1, a straight slit 91 extending along the axial direction is formed in the circumferential direction of the barrel 9. In the usual welding, the welding is performed from the outside of the cylinder 9, and therefore the straight slits 91 appear to protrude radially outward from the outer surface of the cylinder 91, and in the welding process, the positions near the straight slits 91 are inevitably deformed by welding, thereby making the part elliptical.

The utility model provides a gas holder barrel presses rounding equipment extrudees barrel 9 from the whole circumferencial direction of barrel 9 to the holistic precision of control barrel 9 outer disc realizes the coining circle.

As shown in fig. 2, the equipment comprises a workbench 1, a lower die 2 is fixedly arranged on the workbench 1, an upper die 3 is arranged above the lower die 2, a driving device 4 for driving the upper die 3 to move towards the lower die 2 is connected to the upper die 3, and the driving device 4 can be a hydraulic cylinder or other parts and can only drive the upper die 3 to move towards the lower die 2. Further, the lower die 2 and the upper die 3 are all semicircular, a complete circle is formed after the lower die 2 and the upper die 3 are connected, the top surface of the lower die 2 is a lower positioning surface 21 which is sunken downwards, the bottom surface of the upper die 3 is an upper extrusion surface 31 which is sunken upwards, the longitudinal sections of the lower positioning surface 21 and the upper extrusion surface 31 are semicircular, and the radian is matched with the outer circular surface of the cylinder 9 with the standard shape. The lower positioning surface 21 is further provided with a stopper groove 22 for positioning the straight slit 91 on the outer periphery of the cylinder 9.

As shown in fig. 3, when the apparatus is used, the cylinder 9 is first put into the lower die 2 in such a manner that the axis thereof extends in the horizontal direction, and the circumferential position of the cylinder 9 is adjusted so that the straight slits 91 are connected in the limit grooves 22, thereby positioning the cylinder 9 in the lower positioning surface 21, and the lower half outer circumferential surface of the cylinder 9 after positioning is completely wrapped by the lower positioning surface 21. The driving device 4 then drives the upper die 3 to move downwards, so that the upper extrusion surface 31 covers the outer side of the upper half outer circumferential surface of the cylinder 9, and applies force to the cylinder 9 downwards, so that the cylinder 9 is clamped between the upper die 3 and the lower die 2, and the outer surface of the cylinder 9 is deformed during the extrusion process, so that shaping is realized, and the roundness of the cylinder 9 is ensured, because the profiles of the lower positioning surface 21 and the upper extrusion surface 31 are the profiles of the standard cylinder 9. After extrusion for a certain time, the driving device 4 drives the upper die 3 to reset upwards, and the shaped cylinder 9 is taken out of the lower die 2.

The beneficial effects of this equipment are: the whole outer circumferential surface of the cylinder 9 is extruded by the upper extrusion surface 31 and the lower positioning surface 21 which are in the shape of an upper semicircle and a lower semicircle, thereby ensuring the roundness of each position of the cylinder 9 and avoiding that only partial rounding is performed as in the prior art.

As shown in fig. 3, the limit groove 22 is provided at the lowest point of the lower positioning surface 21, so that the straight slit 9 is located right under when the cylinder 9 is mounted on the lower positioning surface 21, so that the vicinity of the position where the straight slit 91 is located can receive the largest force in the radial direction toward the position where the straight slit 91 is located when the cylinder 9 is subjected to the downward pressing force, in which case the vicinity of the straight slit 91 can be smoothly pressed into the circular arc shape even if the hardness of the position in the vicinity of the straight slit 91 is greater than that of other positions.

As shown in fig. 2, the upper mold 3 is provided with a guide assembly 5, the guide assembly 5 includes a guide rod 51 fixedly disposed in a longitudinal direction and a guide plate 52 slidably disposed on the guide rod 51, and the upper mold 3 is fixedly connected to the guide plate 52, so that the upper mold 3 receives the guide of the guide assembly 5 when moving up and down, thereby not deviating from a predetermined track, and ensuring accurate fitting above the upper mold 2.
