Abstract

The invention provides an external circle extruder, and relates to the technical field of extruding equipment. The technical problems that in the prior art, workpiece positioning is inaccurate, and the size is instable after shaping are solved. The external circle extruder comprises a bracket, sliding block inserts, an extruding block, positioning columns and a hydraulic device, slideways are formed in the bracket and internally provided with the sliding block inserts, the extruding block is movably connected with the bracket, the bottom ends of the positioning columns are connected with the extruding block, and the top ends of the positioning columns are slidably connected with the sliding block inserts in the horizontal direction. The hydraulic device upwards jacks the extruding block, thus the extruding block can move upwards so as to drive the sliding block inserts to slide upwards in the slideways, meanwhile, the inner walls of the slideways extrude the sliding block inserts, thusthe sliding block inserts slide along the corresponding positioning columns relative to workpieces in the horizontal direction to extrude and shape the workpieces, the overall extruding process is high in mechanical degree, operation is easier, positioning of the workpieces is more accurate, force bearing is more uniform, the size is more stable, and the quality and the working efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of extrusion equipment, in particular to an extruder. Background technique [0002] Workpieces with rings are usually processed from raw materials through multiple processes to obtain rings with low precision. Therefore, before becoming a finished product, the outer diameter of the ring needs to be reshaped to ensure that the product has no deformation. [0003] The applicant found that the prior art has at least the following technical problems: the existing jigs for extruding circular workpieces are not easy to locate when placing workpieces, and are easy to be misplaced. At the same time, the workpieces have the problem of uneven force , is easily crushed, and the resulting product is dimensionally unstable. Contents of the invention [0004] The object of the present invention is to provide an extruder to solve the technical problems of inaccurate workpiece positioning and unstable dimensions after sh...
