When the workpiece manipulator 320 moves the sleeve to the corresponding workstation, the sleeve can be clamped by cooperating with the upper clamping block 352 and the lower clamping block 353 to facilitate processing of the sleeve.

[0074] Of course, in the specific implementation process, the clamping mechanism 350 can also be a pneumatic clamping hand or a hydraulic chuck or a pneumatic chuck, etc., which will not be described in detail here.

The four groups of clamping hand mechanisms 325 correspond to the first extrusion station, the second extrusion station, the first cutting station and the second cutting station, respectively. The clamping hand mechanisms 325 located at the edge are used to take the sleeve 900 after the inner wall is processed and to deliver the finished sleeve 900, so that the transverse drive mechanism 324 only needs to move a fixed stroke to realize the transfer of the sleeve between the various stations, simplifying the structure of the workpiece manipulator 320 and improving work efficiency.

[0079] Of course, in the specific implementation process, less than five groups of clamping hand mechanisms 325 can be configured to also realize the transfer of the sleeve 900 between various workstations, which will not be described in detail here.

[0080] According to some embodiments of the present invention, Figure 6 As shown, the lifting drive mechanism 322 is a screw mechanism driven by a motor, and the transverse drive mechanism 324 is a cylinder mechanism.

[0081] Of course, in the specific implementation process, the lifting drive mechanism 322 can also be a gear rack mechanism, a cylinder mechanism, etc., and the transverse drive mechanism 324 can also be a motor-driven screw mechanism, etc., which will not be described in detail here.

[0082] According to some embodiments of the present invention, Figure 6 As shown, the gripping hand mechanism 325 is a pneumatic gripping hand. Of course, in the specific implementation process, it can also use an electric gripping hand, which will not be described in detail here.

[0083] According to some embodiments of the present invention, Figure 6As shown, a limiting mechanism 360 is arranged at the first extrusion station. The limiting mechanism 360 is arranged opposite to the extrusion mechanism 330. The limiting mechanism 360 includes a limiting piston cylinder 361 and a limiting block arranged on the piston rod of the limiting piston cylinder 361. Since the maximum deformation force of the sleeve is also the maximum during the first extrusion molding, the limiting mechanism 360 is arranged to press the rear end of the sleeve to reduce the occurrence of the sleeve being pushed backward.

[0084] According to some embodiments of the present invention, Figure 3 , Figure 4 As shown, the inner wall forming mechanism 200 includes a cross workbench 210 arranged on the workbench 100, a workpiece clamping mechanism 220 arranged on the cross workbench 210, and an inner wall cutting mechanism arranged on the workbench 100. The inner wall cutting mechanism includes an inner wall cutting feed mechanism 231, an inner wall cutting rotating mechanism 232 that can be driven to move by the inner wall cutting feed mechanism 231, and an inner wall cutting tool head 233 that can be driven to rotate by the inner wall cutting rotating mechanism 232. The cross workbench 210 is an electric cross workbench driven by a motor screw to realize the two-axis movement of the sleeve. The workpiece clamping mechanism 220 is a pneumatic clamping hand or a hydraulic chuck or a pneumatic chuck, etc. The inner wall cutting feed mechanism 231 includes a lifting mechanism driven by a screw and an axial driving mechanism driven by a screw, so that the inner wall cutting tool head 233 can be used to cut an annular groove on the inner wall of the sleeve to facilitate extrusion molding of the sleeve end.

[0085] Of course, in the specific implementation process, the inner wall forming mechanism 200 can also be a press-formed structure, and a wavy press-formed mold is provided to press out a wavy structure at the end of the sleeve, which can also meet the requirements of extrusion molding, which will not be described in detail here.

[0086] It is easy for those skilled in the art to understand that the above preferred embodiments can be freely combined and superimposed without conflict.

[0087] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
