Vertical extruder die base centering device and corresponding vertical extruder

Abstract

The invention provides a vertical extruder die holder centering device and a corresponding vertical extruder. The vertical extruder die holder centering device comprises two guide rails and a push-pull device, wherein the two guide rails are horizontally arranged and are respectively and slidably clamped with the two sides of a die holder, and the push-pull device can drive the die holder to slide along the guide rails. The vertical extruder die holder centering device also comprises an X-direction adjusting device and a plurality of Y-direction adjusting devices, wherein the X-direction adjusting device comprises X-direction fixing seats and X-direction adjusting screws in threaded connection with the X-direction fixing seats, and the X-direction adjusting screws are arranged along the sliding direction of the die holder and can prop against the die holder; the Y-direction adjusting devices can drive the two guide rails to independently move in the direction perpendicular to the sliding direction of the die holder, and the die holder is hinged with the push-pull device so that the die holder can freely swing in the horizontal direction. The die holder is adjusted by the X-direction adjusting device and the Y-direction adjusting devices, so that the die holder position can be regulated, and the assembly error and machining error of the die holder can be compensated, and thus the machining accuracy of the extruder is ensured.

Description

technical field [0001] The invention relates to extrusion equipment, in particular to a centering device for a mold base of a vertical extruder and a vertical extruder with the centering device for a vertical extruder. Background technique [0002] The mold base of the vertical extruder is fixed on the working surface, and the central hole of the mold base is required to coincide with the axis of the central hole set on the working surface during the extrusion operation. After the mold base is used for a period of time, the mold base will be worn out, and the mold base needs to be disassembled from the vertical extruder for maintenance or replacement. [0003] The applicant previously applied for a publication number of CN102962278A, and the Chinese invention patent titled "a die base moving device for a vertical extruder and a vertical extruder" discloses a die base movement for a vertical extruder The device includes a guide rail and a push-pull device. There are protrudi...

AI Technical Summary

Problems solved by technology

[0004] When the mold base moving device of the above-mentioned vertical extrusion machine is in use, the center position of the mold base is guaranteed by the machining and assembly accuracy. Since there is no adjustment device, when the machining accuracy and assembly accuracy exceed the equipment accuracy requirements, there is no way to adjust the mold base.
