Background technology
The cold-stamped processing method is to utilize the principle of Plastic Deformation of Metal Materials, under the condition of room temperature, the cold conditions metal blank is put into the mold cavity that is contained on the forcing press, under powerful pressure and certain velocity function, force metal blank to produce Plastic Flow, by the gap of punch and die or the outlet of die, extrude solid member hollow or that section is less than blank section, can obtain required definite shape and size, it is continuous that the part that adopts the metal precision plastic forming process to process has metal streamline, the intensity high, security is higher, has wide economic benefit and social benefit.After adopting vibration and cold extrusion combining, can reduce the frictional force of blank and die surface, reduce internal stress, thereby reach the characteristics that reduce extruding force.
Since the resistance of deformation when nineteen fifty-five F.Blaha and B.Langenecker have disclosed first that additional Under Ultrasonic Vibration kinetic energy reduces the plastic deformation of monocrystal zinc, many scholars of countries in the world for the application start of vibration in Metal Forming theoretical and experimental study extensively and profoundly.Present stage vibration processing is mainly used in the punching, shearing, pressure-sizing of drawing, the metal material of wire rod, tubing and heterotypic material, the process such as rolling.The exciting mode that adopts is mainly take the power ultrasonic vibration as main, and more or less all exist input power limited, produce that exciting force is less, frequency and amplitude be difficult to the problems such as adjusting, and most research work are only carried out in the experiment aspect, and practical engineering application is worth and remains further to be improved.
Summary of the invention
For can not realize large scale part dither and the size of formed part precision that overcome existing cold extrusion die fail to be guaranteed, to regulate the deficiency of trouble, a kind of large vibration power output, higher vibration frequency and less amplitude of providing enough is provided the utility model, when finishing the complex parts vibration-extrusion and can guarantee its dimensional accuracy, the cold-stamped swing die that is used for easy to adjust.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of for the cold-stamped swing die, comprise builder, described builder comprises punch and die, described punch is fixedly connected with cope match-plate pattern, described die be positioned at punch under, described die is installed in the die case, described swing die tool also comprises vibrator, described vibrator involving vibrations module and exciting valve, described vibration module involving vibrations platform and pedestal, described shake table is fixedly connected with die case, described shake table one circle is offered laterally zygomorphic annular groove, the cross section of described annular groove is curved, the lower surface middle part of described shake table is provided with low groove, described low groove is communicated with the annular groove of described shake table lower surface, described shake table is nested in the mounting groove of pedestal upper surface, described pedestal is provided with the oil duct for the hydraulic oil turnover, one end of described oil duct is communicated with described low groove, the other end of described oil duct is communicated with the exciting valve, be provided with in the described pedestal and regulate the chamber, described adjusting chamber is communicated with described oil duct, and in the described adjusting chamber piston that is used for realizing adjusting is installed, described piston is connected with the regulating piston bar, and described pedestal is fixedly connected with lower bolster.
Further, described punch is placed in the punch trim ring, and described punch trim ring is fixedly connected with the punch bracing ring, and the punch cushion block is installed in the described punch bracing ring, the upper end in contact of described punch cushion block and punch, punch bracing ring, punch trim ring are fixedly connected with cope match-plate pattern by disk nut; Described die case is positioned on the die cushion block, and described die cushion block is positioned on the vibration module.
Further again, described cope match-plate pattern is provided with pilot hole, and described lower bolster is provided with lower pilot hole, and guide rod passes respectively described upper pilot hole and lower pilot hole.
Technical conceive of the present utility model is: the Material Flow when the high frequency flutter is conducive to part forming, and can improve the Frotteurism between metal and the mould and reduce extruding force, thereby reach the purpose of antifriction load shedding.In addition, because amplitude is small, also can not affect the dimensional accuracy of drip molding.
The high frequency flutter is combined with extrusion molding, reduce metal flow stress, metal and the die surface frictional force in the part forming process and reduce extruding force, particularly eliminate or improve the phenomenon that final stage extruding force step is ascended to heaven.As vibration source, its output exciting force is large by hydraulic pressure, and vibration frequency is high, and frequency and amplitude can be realized stepless adjustable.In the situation that need not to strengthen equipment tonnage, also can push smoothly the difficult part that is shaped under the normal temperature, have important theory significance and Practical background.For China of cold extrusion equipment and process backwardness, large complicated precision form spare height dependence on import, meaning is particularly great.
The beneficial effects of the utility model are mainly manifested in: can provide enough large vibration power output, higher vibration frequency and less amplitude, when finishing the complex parts vibration-extrusion and can guarantee its dimensional accuracy, easy to adjust
Description of drawings
Fig. 1 is for being used for the structure chart of cold-stamped swing die.
Fig. 2 is the structure chart of vibrator.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See figures.1.and.2, a kind of for the cold-stamped swing die, comprise builder, described builder comprises punch 5 and die 7, described punch 5 is fixedly connected with cope match-plate pattern 1, described die 7 be positioned at punch 5 under, described die 7 is installed in the die case 8, described swing die also comprises vibrator 10, described vibrator 10 involving vibrations modules and exciting valve, described vibration module involving vibrations platform 13 and pedestal 14, described shake table 13 is fixedly connected with die case 8, described shake table 13 1 circles are offered laterally zygomorphic annular groove, the cross section of described annular groove is curved, the lower surface middle part of described shake table 13 is provided with low groove, described low groove is communicated with the annular groove of described shake table lower surface, described shake table 13 is nested in the mounting groove of pedestal 14 upper surfaces, described pedestal 14 is provided with the oil duct for the hydraulic oil turnover, one end of described oil duct is communicated with described low groove, the other end of described oil duct is communicated with the exciting valve, be provided with in the described pedestal 14 and regulate chamber 15, described adjusting chamber 15 is communicated with described oil duct, and the 15 interior installations of described adjusting chamber are used for realizing the piston of adjusting, described piston is connected with the regulating piston bar, and described pedestal 14 is fixedly connected with lower bolster 12.
Further, described punch 5 is placed in the punch trim ring 4, described punch trim ring 4 is fixedly connected with punch bracing ring 3, described punch bracing ring 3 interior installation punch cushion blocks 2, the upper end in contact of described punch cushion block 2 and punch 5, punch bracing ring 3, punch trim ring 4 are fixedly connected with cope match-plate pattern 1 by disk nut; Described die case 8 is positioned on the die cushion block 9, and described die cushion block 9 is positioned on the vibration module.
