Die pressing device of extruding machine and die fixing device

Abstract

The invention provides a die pressing device of an extruding machine, which is mounted at the upper side of an extruding machine die seat, wherein the die seat has a U-shaped groove structure with an upward opening; a module can be arranged into the die seat from a mounting opening at the upper side of the die seat; the pressing device comprises a power device and a pressing head; the power device faces to the center of the die seat and is vertically mounted at the upper side of the die seat; the pressing head is mounted at the lower end of the power device; and the power device can downwards push the pressing head to tightly press the module in the die seat. The power device is utilized for controlling the pressing and the looseness of the module by the pressing head so that each part of the module can be well pressed. The invention further provides a die fixing device provided with the pressing device, comprising a front beam, an upper guide frame, a lower guide frame, the die seat, the module, the die pressing device, an intra-die shearing cylinder, and main shears. Therefore, the pressing device is applied to the extruding machine and is matched with the pressing device so as to well guarantee the operation of the extruding machine.

Description

technical field [0001] The invention relates to extruder equipment, in particular to a die pressing device and a die fixing device for a horizontal extruder which can effectively fix a die set. Background technique [0002] The main components of the existing horizontal extrusion machine are the front beam, the extrusion cylinder and the extrusion rod. Generally, the extrusion rod extrudes the ingot from one side to the other side in the extrusion cylinder, and the other side of the extrusion cylinder The front beam on one side is fixed with a module through the mold base. The die set consists of circular die set parts: void pad, shear pad and die sleeve. Generally, the mold base is a U-shaped groove structure with an upward opening, and the space pad, shear pad, and mold sleeve are sequentially loaded into the mold base from the upper opening of the mold base, and the mold pad and mold are installed in the mold sleeve. The cylinder presses these module components in the m...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the upper part of the mold base is open, the radial positioning of the space pad, shear pad and die sleeve is not stable during extrusion.

[0005] 2. When the shearing device between the mold base and the extrusion cylinder needs to cut the excess pressure of the product, the space pad, shear pad, and mold sleeve are prone to loosening and shifting
