In this embodiment, the diameter of the discharge hole 141 is smaller than the diameter of the blanking cap 19, and the upper portion of the discharge hole 141 is provided with a flared opening, the blanking cap 19 can enter the flared opening of the discharge hole 141, that is, the diameter of the flared portion of the discharge hole 141 is larger than the diameter of the blanking cap 19, such an arrangement can not only enable the blanking cap 19 to enter the flared opening of the discharge hole 141, but also avoid the situation that the blanking cap 19 directly falls into the workpiece 4 from the discharge hole 141 in the process of pushing the blanking cap 19, because a distance is usually provided between the discharge hole 141 and the workpiece 4, the situation that the blanking cap 19 cannot smoothly enter the workpiece 4 easily occurs in the process that the blanking cap 19 directly falls into the workpiece 4 from the discharge hole 141, or the blanking cap 19 can fall into the workpiece 4, but the blanking cap 19 is easily tilted and inclined in the falling process, so that the blanking cap 19 falling into the workpiece 4 cannot be completely matched with the inner stop opening of the workpiece 4, resulting in poor air tightness between the clinched cap 19 and the workpiece 4.

However, in this embodiment, since the flaring is disposed on the discharging hole 141, and the diameter of the discharging hole 141 is smaller than that of the blocking cover 19, the blocking cover 19 can be stopped after being pushed into the discharging hole 141, so that it is more convenient for the punch 20 to make the magnet 22 at the bottom of the feeding rod 21 adsorb and fix the workpiece 4 located in the discharging hole 141 and then press the workpiece 4 into the workpiece 4 in the later stage, and the blocking cover 19 can be placed in the workpiece 4 more smoothly.

The specific implementation process is as follows: the plurality of the blanking caps 19 are placed in the discharging barrel 13 at one time, because the bottom end of the discharging barrel 13 is an open end, the blanking cap 19 at the bottommost part of the discharging barrel 13 falls on the feeding cover plate 14 for waiting, the punch 20 is positioned above the discharging hole 141 at the moment, the bottom end of the workpiece 4 (namely, a sliding fork) is placed in the positioning block 3, the workpiece 4 is positioned between the two clamping jaws, then the workpiece 4 extends out through the piston rod 25 of the driving oil cylinder 23, at the moment, the tensioning cylinder 26 drives the two wedge blocks 28 to slide, and the clamping blocks 5 of the two clamping jaws are driven to be mutually folded to clamp and fix the workpiece 4.

Then the output shaft of the driving cylinder 15 extends out, so that the material pushing plate 17 slides the blocking cover 19 at the bottom of the material discharging barrel 13 towards the material discharging hole 141, the blocking cover 19 is pushed into the flaring of the material discharging hole 141 to stay, the pressing plate 6 is pressed downwards by the punching cylinder, the punch 20 moves downwards in the downward movement process of the pressing plate 6, the magnet 22 at the bottom end of the material feeding rod 21 in the punch 20 adsorbs and fixes the blocking cover 19 in the downward movement process of the punch 20, and the blocking cover 19 can deform due to the rebound property of the blocking cover 19, so that the blocking cover 19 deforms and smoothly passes through the material discharging hole 141 and enters the inner stop of the workpiece 4 in the continuous downward movement process of the punch 20.

Because the blanking cover 19 is under the action of the magnet 22, the punch 20 can keep the blanking cover 19 stably placed into the workpiece in the downward punching process, and the situation that the blanking cover 19 cannot successfully fall into the workpiece 4 or the situation that the blanking cover 19 is inclined after falling into the workpiece 4 to influence the air tightness between the blanking cover 19 and the workpiece 4 is effectively avoided.

After the blanking cap 19 is conveyed to the inner spigot of the workpiece 4, because the punch 20 continuously moves downwards, the punch 20 presses the blanking cap 19 on the workpiece 4, and finally the blanking cap 19 is riveted on the workpiece 4, and then the pressing plate 6 is driven by the punching cylinder to move upwards, so that the punch 20 is separated from the blanking cap 19 pressed in the workpiece 4 to reset.

The foregoing is merely an example of the present invention and common general knowledge in the art of designing and/or characterizing particular aspects and/or features is not described in any greater detail herein. It should be noted that, for those skilled in the art, without departing from the technical solution of the present invention, several variations and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
