Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] The production process of the integrated oil storage cylinder is carried out according to the following steps: cutting strips→blanking and punching the bowl→primary drawing→flat opening→annealing→pickling-phosphating-saponification→second drawing→three drawing→flat opening→grinding Round → closed → flat overall length → chamfering, deburring → car ring groove; punching mold and press are used for blanking and punching; corresponding molds and hydraulic presses are used for primary drawing, secondary drawing and tertiary drawing respectively; annealing furnace is used for annealing , the temperature is 700-780°C, and the time is 20-40min; the closing mold and closing machine are used for closing.

[0029] The extension coefficient m1 of the blanking punch is 0.52, and the extension coefficient m2 of one extension is 0.78. Both the second and thir...

Abstract

The invention discloses a manufacturing technology of an integrated oil storage cylinder and an extension mould, belonging to the machining technology and the mould technical field. The technology comprises the following steps: shearing bar stock, cupping blank, primary extending, leveling opening, annealing, pickling, phosphating, saponifying, secondary extending, third extending, leveling opening, grinding excircle, closing up, leveling overall length, chamfering, burring and machining a circular groove; the mould comprises an upper die base (11) and a lower die base (12), wherein, the upper die base (11) is connected with a stamping terrace die (2) through an upper die pressing ring (1) and an upper die quilt cap (13); the lower die base (12) is provided with an unloading ring (6), a lower die (5), a lower pressing ring (8), an upper die (4), an upper pressing ring (9) and a locating ring (3) from the bottom to top; the lower die (12) is connected with a lower quilt cap (10); and a discharging ring (6) is composed of three isotonic arc blocks and two extension springs (7) embedded in the groove of the external ring of the discharging ring. The manufacturing technology of the invention is suitable for manufacturing oil storage cylinders in shock absorbers for automobiles.

Description

Technical field [0001] The invention relates to a production process of an oil storage cylinder in a shock absorber, in particular to a production process of an integrated oil storage cylinder and an extension mold, and belongs to the technical field of mechanical processing technology and molds. Background technique [0002] The key component of the automobile shock absorber is the oil storage tank. At present, the welded oil storage tank is used, that is, the cylinder body is closed on the closing machine and then welded to the bottom cover. The disadvantages are that the concentricity between the conical surface of the bottom cover and the cylinder is not easy to control, the welding strength is difficult to guarantee, and there is a hidden danger of air leakage. Contents of the invention [0003] In order to overcome the disadvantages of the existing welded oil storage cylinder, the invention provides a manufacturing process of an integrated oil storage cylinder and a ...
