Abstract
The present invention relates to a process for producing a ladle by using a cooling and pressing method. Firstly, a blank is arranged between a core mould and an apex to be tightly clamped, a screw rod is adjusted so that an exerting wheel rotates by the rotation of the core mould, and thus, the blank is formed (generally exerted). Then, the blank is secondarily strongly exerted, the edge of the blank is thinned, and the preparation of the ladle is finished by trimming and handle weld. A cold spinning machine tool improves the existing lathe, and a hemispherical core mould is additionally arranged on a main shaft. Because a hemispherical tail top is additionally arranged at a tailstock of the machine tool, a sector gear is arranged on the machine tool face, a gear rack which is fixed on a slide carriage and the sector gear form a kinematic pair, and an exerting wheel frame which is provided with the exerting wheel is arranged on the sector gear, the method and the equipment overcome the defect existing in the existing processing method, have the advantages of simple process and low cost, and can be widely used for processing the ladle.
Description
The present invention relates to a kind of Processes and apparatus that adopts the cold spinning method to produce strockle.
The method of producing at present strockle normally heat is pounded method or is used the friction press manufacturing, and it mainly is that operator's labour intensity is big, efficient is low that the heat method of pounding is produced shortcoming that strockle exists, and it is long to produce used man-hour.Produce strockle with friction press and need use the 5-6 mold, need through repeatedly (cold pounding) handled in drawing and forming and then process cold-working, this technology not only operator's labour intensity is big, and equipment investment is big, big energy-consuming, cause product cost height, of poor quality, being prone to the noise of producing in the defectives, particularly production process such as wrinkling, drawing crack has seriously influenced the healthy of operator.
Task of the present invention is to overcome the deficiencies in the prior art, designs that a kind of technology is simple, with low cost, the cold spinning of the good product quality produced is produced the method and apparatus of strockle.
Task of the present invention realizes as follows: a kind of method of processing strockle on the cold spinning lathe, at first blank is put into core and top middle the clamping, adjusting leading screw then makes spinning roller can be driven its rotation by the rotation of core, make blank shaping (general revolving), at last, secondary revolves by force, makes blank edge attenuate.
Adopt the cold spinning lathe of said method, be that existing lathe is improved, on main shaft, install the hemispherical core additional, install sphere tail top additional at tail stock, be fixed on a base plate is arranged on the bed surface, sector gear that is fixed with central shaft in center of rotation is contained on the bed surface base plate sector gear is swung around central shaft by being contained in bearing on the central shaft, be fixed with spinning roller frame fixed head on the sector gear, rotatable spinning roller is housed on the fixed head, vertically the side of slide carriage is installed with tooth bar, when this tooth bar and sector gear constitute motion, the guiding mechanism that can make the two relative motion is set between spinning roller frame fixed head and spinning roller frame, be positioned at spinning roller frame fixed head below, be installed in and the swing rolling wheel frame be housed below the sector gear, roller is housed on it.
The above-mentioned said guiding mechanism that makes the two relative motion that is provided with between spinning roller frame fixed head and spinning roller frame comprises leading screw that is driven its rotation by handwheel that is fixed on the spinning roller fixed mount and the screw that is fixed on the spinning roller frame.
The present invention is owing to adopt the cold spinning method to revolve and revolve by force the making that twice spinning just can be finished strockle through general, therefore it is simple, with short production cycle to have technology, the measured advantage of product cost low-quality, simultaneously, adopted the cold spinning method, the blank of suppressing the strockle use of identical bore can be little than the blank that stretches, heat is pounded use, therefore can save material.
Fig. 1 is a process chart of the present invention;
Fig. 2 is a cold spinning lathe front view;
Fig. 3 is a cold spinning lathe vertical view;
A most preferred embodiment of the present invention, as figure, the method of cold spinning processing strockle is: at first blank is put into top middle clamping of centralized positioning frame and core on the cold spinning lathe, adjusting leading screw makes spinning roller can be driven its rotation by the rotation of core, make blank moulding (general revolving), secondary revolves by force and makes blank edge attenuate just finish the cold spinning process of strockle, and welding handle at last just becomes the finished product strockle.
Realize the cold spinning lathe of said method, be that existing lathe is improved, install sphere tail top 4 additional at tail stock, on main shaft, add hemispherical core 1, be fixed on a base plate 8 is arranged on the bed surface, bed surface is provided with a sector gear 6, constitute kinematic pair with sector gear, be fixed on a tooth bar is arranged on the vertical slide carriage of lathe, be used to drive the sector gear motion, the center fixation of sector gear has central shaft 9, central shaft is contained on the bed surface base plate 8 by pressure bearing 10 sector gear is swung around central shaft, be fixed with spinning roller frame fixed head 11 on the sector gear, rotatable spinning roller 3 is housed on the fixed head, between spinning roller frame fixed head 11 and spinning roller frame 7, be provided with the guiding mechanism that can make the two relative motion, this guiding mechanism comprise be fixed on the rotary fixing frame by handwheel drive the leading screw of its rotation and fixedly the screw on the spinning roller frame form, be positioned at spinning roller fixed head below, be installed in swing turning rolls 12 is housed below the sector gear, roller 13 is housed on it, and the effect of swing roller is guarantee sector gear steady.
The process of this device is: at first blank is put into core and top middle the clamping, the adjustment leading screw makes and rotatably compresses blank, makes spinning roller can be driven its rotation by the rotation of core simultaneously, makes blank shaping (general revolving).Handwheel drove leading screw and drives spinning roller and press to blank spinning roller is revolved by force when secondary revolved by force, with blank edge attenuate.Cut edge at last, the electrode holder hand has just been finished whole process.The cold spinning principle of strockle is that spherical core and blank rotate, and spinning wheel rotates, selects pinch roller to rotate the result of three kinds of synthetic stacks of motion with sector gear.
