The invention discloses a feeding cylinder device for extruding machines. The feeding cylinder device comprises a feeding cylinder body, a piston rod, a piston body and a slide block, wherein the slide block is arranged on the lower part of the feeding cylinder body, the piston rod is horizontally arranged in the feeding cylinder body, and a DAS combined seal ring is arranged outside the piston body at the fixed end of the piston rod; and an end part of the piston body is provided with a circle of stop washer which is locked by nuts, the tail end of the feeding cylinder body is provided with a rear cylinder cover, and the feeding cylinder body is movably connected to a support. The device disclosed by the invention has the advantages that: through arranging a circle of DAS combined seal ring outside the piston body, the overall sealing of a piston mechanism is improved, and the flexibility of the piston rod is improved; and through arranging the stop washer on a piston cap and locking the stop washer by nuts, the stability of connecting components in the cylinder body is improved, and the durability is improved.
Description
technical field [0001] The invention relates to a horizontal profile extruder device, in particular to a feeding cylinder device of the extruder. Background technique [0002] When the existing pushing mechanism used in horizontal profile extruder pushes the spindle, because the structural components of the feeding device are not tight enough and the sealing around the internal piston is poor, the transmission efficiency has been low indirectly and it cannot be fully guaranteed. Accuracy problems, which affect the efficiency of the overall equipment, spent a lot of time and manpower on the later maintenance. Contents of the invention [0003] In view of the above defects, the object of the present invention is to provide a feeding cylinder device of an extruder that has a high-strength sealing structure, the internal components of the cylinder body are connected and fastened, is conducive to improving production efficiency, and is easy to install and maintain, so as to sol...
