The third stopping plate 330 may be a strip plate, and is inserted into the grooves of the lower die 110 and the upper left die 120, so as to limit the position of the vibrator 20 and the third shoulder 13. The third stopper plate 330 is pulled out of the lower mold 110, thereby releasing the stopper function.
Fig. 8 shows a structure of the third stop plate 330, the core shaft 10 is pushed by the pressing mechanism 200, and the third shaft shoulder 13 is pressed on the vibrator 20 under the combined action of the pressing mechanism 200, the third mold cavity and the third stop plate 330. The third shaft shoulder 13 is limited by the third stop plate 330, so that the third shaft shoulder 13 and the oscillator 20 are pressed in place, and at this time, the processed antenna oscillator is a semi-finished product.
, as shown in fig. 9, a second stop groove 321 is provided on the second stop plate 320, the second stop groove 321 allows the shaft shoulder 11 to pass through and block the vibrator 20, when the second shaft shoulder 12 is pressed, the vibrator 20 pressed with the second shaft shoulder 12 is pressed onto the second shaft shoulder 12 after passing through the shaft shoulder 11, so that the second stop groove 321 should enable the shaft shoulder 11 to pass through, so that the spindle 10 continues to move, so that the second shaft shoulder 12 is pressed onto the vibrator 20, the second stop groove 321 may be a circular hole with a diameter between the diameter of the shaft shoulder 11 and the outer diameter of the vibrator 20, so that the second stop plate 320 and the vibrator 20 can avoid the shaft shoulder 11 while having an equalized limit pressure, so that the shaft shoulder 11 is allowed to pass through the spindle, the second stop groove 321 may also be a U-shaped groove, and the opening of the U-shaped groove faces the upper die, so that when the vibrator 20 pressed onto the second shaft shoulder 12 is not required to be pulled down, the stop plate 320 can be released, and the second stop plate can be pulled down at any time, so that the second stop plate 20 can be pulled down.
In this embodiment, the lower die 110 and the right upper die 130 are provided with groove bodies for allowing the second stopper plate 320 to penetrate therethrough, and when the second stopper plate 320 is inserted between the lower die 110 and the right upper die 130, specifically, when the second stopper plate is inserted into the second stopper groove 321 in a circular hole shape and is coaxial with the vibrator 20, a limiting effect is formed on the vibrator 20. The second stopper plate 320 is pulled out from the lower mold 110, so that the limit of the vibrator 20 by the second stopper plate 320 is released.
The second stopper plate 320 is disposed on the right side of the second cavity, i.e., between the second cavity and the third cavity, and the transducer 20 is disposed on the left side of the second stopper plate 320. Thus, it can be understood that the pressing mechanism 200 only needs to act on the shoulder of the mandrel 10 to drive the mandrel 10 to move, and the pressing of the second shoulder 12 and the vibrator 20 is completed through the combined action of the second mold cavity, the pressing mechanism 200 and the second stop plate 320.
As shown in FIG. 10, the th stopper plate 310 is provided with a th stopper groove 311, the 0 th stopper groove 311 allows the mandrel body to pass through, the mandrel body extends from the end surface of the 1 shaft shoulder 11, when the 2 th shaft shoulder 11 is pressed on the vibrator 20, the th stopper plate 310 limits the position of the vibrator 20 and simultaneously avoids the mandrel body passing through the vibrator 20, the th stopper groove 311 is provided so that the mandrel body does not form any block for the pressing of the th shaft shoulder 11 when the th shaft shoulder 11 and the vibrator 20 are pressed, the th stopper groove 311 can allow the mandrel body to pass through but cannot allow the vibrator 20 to pass through, the th stopper groove 311 can be a round hole, in the embodiment, the th stopper groove 311 is a U-shaped groove, and the end of the U-shaped groove facing the upper die is open.
The distance between the stop plate 310 and the second stop plate 320 is set to be equal to the distance between the shaft shoulder 11 and the second shaft shoulder 12, so that the shaft shoulder 11 and the second shaft shoulder 12 are pressed and molded for one time, at this time, the core shaft 10 of the antenna element forms the element 20 on the core shaft 10 through two times of pressing.
However, during the press-fit molding, the deformation of the mandrel 10 is not controllable, so that the th shoulder 11 may not be pressed with the vibrator 20, and at this time, the th shoulder 11 needs to be pressed for the second time.
In this embodiment, the th die cavity left section is the round hole die cavity, and the right section is the semicircle orifice die cavity, is equipped with the cell body that allows th backstop board 310 to alternate on the lower mould 110, and th backstop board 310 is worn out through the cell body and is spacing to oscillator 20, and when shaft shoulder 11 needs to carry out the pressfitting for the second time, th shaft shoulder 11 is pressfitting for the pre-pressfitting with the th time of oscillator 20.
Because the th die cavity is not a complete cavity, when the th shaft shoulder 11 is pressed twice, the mandrel 10 can be pulled back to the left, so that the vibrator 20 on the th shaft shoulder 11 is arranged on the left side of the second stop plate 320, and the th shaft shoulder 11 is pressed twice in the second die cavity, so as to achieve a good pressing and forming effect.
In another embodiment, cavity is a full bore cavity, and shoulder 11 is precisely press-molded directly into cavity.
, the pressing mechanism 200 includes a pushing head 210 disposed between the second mold cavity and the third mold cavity, the pushing head 210 cooperates with the third stop plate 330 to press the vibrator 20 on the third shoulder 13, the pushing head 210 cooperates with the second stop plate 320 to press the vibrator 20 on the second shoulder 12, and the pushing head 210 cooperates with the stop plate 310 or the second stop plate 320 to press the vibrator 20 on the shoulder 11.
Thus, as described above, the pushing head 210 drives the mandrel 10 to move by acting on the shoulder, so as to press the shoulder against the vibrator 20. The stitching mechanism 200 moves between the upper left mold 120 and the upper right mold 130 on the upper side of the lower mold 110 to drive the exposed cavity/mandrel 10 on the lower mold 110 to move.
