[0027] It should be noted that the shell conveying assembly is a prior art. In the prior art, the shell conveying device is generally a conveyor belt or a transmission turntable, which can achieve the effect of periodically conveying the shell.

[0028] In the above embodiment, the steel shaft conveying assembly includes a steel shaft vibration disk 2 and a steel shaft conveying pipe 14, one end of the steel shaft conveying pipe 14 is connected to the discharge end of the steel shaft vibration disk 2, and the other end of the steel shaft conveying pipe 14 is connected to the steel shaft in-place assembly.

[0029] In the above embodiment, the steel shaft in place component includes a staggered body 10, a staggered block 11 and a staggered cylinder 12. A steel shaft channel is opened in the staggered body 10, and a steel shaft entry channel and a downward pressure channel connected to the steel shaft channel are opened on the top surface of the staggered body 10. The steel shaft entry channel is at one end of the steel shaft channel, and the downward pressure channel is at the other end of the steel shaft channel. The lower end of the downward pressure channel extends to the bottom surface of the staggered body 10 to form a steel shaft outlet. The steel shaft entry channel is connected to the steel shaft conveying pipe 14, and the power output end of the pressing component just extends into the downward pressure channel. A pushing channel is opened on the side wall of one end of the staggered body 10, and one end of the staggered block 11 extends into the pushing channel. The other end of the staggered block 11 is connected to the power output end of the staggered cylinder 12. When the staggered cylinder 12 is started, the staggered block 11 can push the steel shaft that enters the steel shaft channel from the steel shaft entry channel into the downward pressure channel.

[0030] In the above embodiment, the steel shaft in place assembly further includes a steel shaft guide sleeve 8, which is vertically arranged at the steel shaft outlet on the bottom surface of the staggered body 10, and the two are interconnected.

[0031] In the above embodiment, the pressing assembly includes a pin 5 and a servo cylinder 3. The servo cylinder 3 is arranged at the top of the descending assembly, and the power output end of the servo cylinder 3 is vertically downward. The pin 5 is arranged at the power output end of the servo cylinder 3, and the lower end of the pin 5 extends into the downward pressing channel.

[0032] In the above embodiment, the descending assembly includes a descending body, a descending cylinder 13, a compression shell and a compression shell cylinder 7. The descending body is movably arranged on the main frame 1, and the power output end of the descending cylinder 13 is transmission connected with the descending body to drive the descending body to rise or descend.

At this time, the steel shaft vibration plate 2 vibrates and discharges the material, so that the steel shaft is transmitted to the staggered body 10 through the steel shaft conveying pipe 14. The descending cylinder 13 is started to drive the descending body to descend until the steel shaft guide sleeve 8 is aligned and fits the pressing position. The in-place sensor 9 senses that the steel shaft enters the steel shaft channel and starts the staggered cylinder 12 to move the staggered block 11 and push the steel shaft to move into the pressing channel. At this time, the steel shaft is above the steel shaft guide sleeve 8. The steel shaft falls into the steel shaft guide sleeve 8 under the action of its own gravity. The servo electric cylinder 3 is started to drive the ejector pin 5 to press the steel shaft in. During the pressing process, the pressure sensor 4 detects the pressure of the ejector pin 5, and the displacement sensor 6 detects the insertion depth of the steel shaft.
