The invention provides a ceramic tube extrusion molding machine. The ceramic tube extrusion molding machine comprises an automatic feeding device, a mixing and feeding device, an extrusion device, a vacuumizing device and a driving device, the automatic feeding device is connected with a feeding port of the mixing and feeding device and used for conveying pug into the mixing and feeding device. The mixing and feeding device comprises a pugging barrel and a double-helix structure which is arranged in the pugging barrel and meshed in different directions, and the double-helix structure is used for shearing and uniformly mixing pug and then conveying the pug to the extrusion device; the vacuumizing device is connected with the tail end of the material mixing and conveying device and is used for discharging gas mixed in the pug in the mixing and conveying processes; and the driving device is used for driving the mixing and feeding device and the extruding device to operate. The pug is effectively sheared and uniformly mixed through a double-helix structure which is meshed in different directions, so that the shearing and mixing uniformity of the pug is effectively enhanced, and the plasticizing quality of a green body is improved; and gas mixed in the pug is discharged through the vacuumizing device, the bubble defect in the ceramic tube is reduced, and the reliability of the ceramic tube is improved.

It includes a mold base, an upper mold-closing base, a lower mold-closing base, a turntable, a turntable servo assembly, a mold-closing linkage assembly, a mold-closing servo assembly, and a mold-closing fine-tuning assembly. This application has the effects of reducing injection molding machine energy consumption, reducing pollution, and improving mold-closing accuracy.

This invention proposes a single-shear apparatus and shearing method for uniform shear strain distribution. The shearing method includes installing a shearing assembly, loading the sample into the stack of plates of the shearing assembly, installing a vertical loading device and a shear force loading device, applying a vertical load to the sample to consolidate the sample, installing a left-side sliding limit device, and applying a horizontal load to the consolidated sample for shearing. This invention can precisely control the shearing direction, solve the problem of shear force direction deflection in the prior art, and enable uniform shearing of the sample, ensuring uniform vertical shear strain distribution.
