Embodiment 1

[0019] like figure 1 As shown, the present embodiment includes: guide post 15, guide sleeve 16, lower mold handle 10, lower template 11, bolt 17, pin 18, upper mold mechanism and vibration generating device. The upper mold mechanism includes: a punch 14 , an upper template 12 , an upper mold handle 19 , a mold handle fixing plate 20 , a force sensor 21 and a sensor fixing plate 13 . The upper die mechanism is connected with the press through the upper die handle 19, and in this embodiment, the upper die mechanism moves along the guide post 15 in the vertical direction to realize the drawing action. The punch 14 is embedded in the upper template 12 . The upper template 12, the sensor fixing plate 13, and the mold handle fixing plate 20 are connected successively from bottom to top. Force sensor 21 is placed in the groove in the big head of upper die handle 19, and the big part of upper die handle 19 is blocked by die handle fixed plate 20, thereby makes force sensor 21 lower ...

Embodiment 2

[0025] Utilize the three-dimensional ultrasonic vibration assisted drawing processing device of the miniature metal thin-walled cup described in embodiment 1 to carry out the processing of miniature metal parts, adopt the following steps:

[0026] 1) Fix the upper mold handle 19 and the lower mold handle 10 on the upper and lower clamps of the press respectively, and move the upper clamp of the press down so that the lower end of the guide post 15 penetrates into the guide sleeve 16.

[0027] 2) Place the blank on the die 9, move down the clamp on the press, and stop the press when the punch 14 just touches the blank.

[0028] 3) Turn on the signal power of the X-axis semi-annular piezoelectric ceramic 1, the Y-axis semi-annular piezoelectric ceramic 2 and the Z-axis annular piezoelectric ceramic 3 respectively, so that they vibrate at the working frequency. And after being amplified by the horn 7, the three-dimensional amplitude is transmitted to the die 9.

[0029] 4) Start...

Abstract

The invention discloses a three-dimensional ultrasonic vibration auxiliary deep drawing machining device of a mini-type metal thin wall cup piece in the field of metal plastic machining. The three-dimensional ultrasonic vibration auxiliary deep drawing machining device comprises a vibration generating device, a lower die mechanism, a male die, an upper die mechanism and a female die fixed to the top of an amplitude rod. The upper die mechanism is connected with the lower die mechanism, and the male die is fixed to the middle of the lower surface of the upper die mechanism. The vibration generating device comprises a back energy converter fixing rod, a Z-axis annular piezoelectric ceramic, a fixing disc, two sets of X-axis semi-annular piezoelectric ceramics with the reverse polarities, two sets of Y-axis semi-annular piezoelectric ceramics with the reverse polarities, a front energy converter fixing rod and an amplitude rod, wherein the back energy converter fixing rod, the Z-axis annular piezoelectric ceramic, the fixing disc, the two sets of X-axis semi-annular piezoelectric ceramics with the reverse polarities, the two sets of Y-axis semi-annular piezoelectric ceramics with the reverse polarities, the front energy converter fixing rod and the amplitude rod are connected in series and fixed from bottom to top in sequence. The fixing disc and the lower die mechanism are fixed, and the female die corresponds to the male die in position. The defect of the corrugation of a thin wall is overcome, the pressure on a blank to be machined from the side wall of the female die can be adjusted conveniently, the friction between the side wall and the blank is reduced, the deformation capability of materials is improved, and the deep drawing limitation is improved.

Description

technical field [0001] The invention relates to a device in the field of metal extrusion, in particular to a three-dimensional ultrasonic vibration-assisted deep-drawing processing device for miniature metal thin-walled cups. Background technique [0002] With the continuous improvement of people's requirements for the portability of electronic products, the volume of electronic products is getting smaller and more powerful, so the application and demand of miniature metal thin-walled cups are on the rise. This has brought a technical challenge to the manufacturing industry: how to produce high-performance miniature metal thin-walled cups in large quantities. Metal plastic processing is widely used in mass production of metal parts due to its advantages of high material utilization rate, good mechanical properties of products, and high production efficiency. However, metal plastic processing methods also have some defects, such as large forming force, poor processing surfac...
