an extruder

Abstract

The invention discloses a hole extrusion machine. The hole extrusion machine comprises a base; a positioning clamp and guide ways are disposed on the base; the guide ways are parallel to each other in the vertical direction; the guide ways are in sliding fit with grooves in a positioning plate; a fixing seat is disposed at the top end of the guide ways; a motor spindle on the fixing seat is connected with a ball screw; the ball screw is in screw thread fit with a ball nut in the positioning plate; a magnetic force pressing head is disposed on the lower end face of the positioning plate; a hole extrusion blade is attracted to the lower end face of the magnetic force pressing head; the hole extrusion blade and the positioning clamp are coaxial; a motor is driven through a programmable logic controller (PLC) control circuit. The hole extrusion machine is good in hole extrusion effect, high in machining accuracy, stable during operation, low in noise and capable of avoiding rigid impact on the hole extrusion blade during returning, and prolongs the service life of the hole extrusion blade, and the small-bore batch hole extrusion machining is achieved.

Description

technical field [0001] The invention belongs to a hole diameter processing device, in particular to a hole extrusion machine. Background technique [0002] When processing aluminum alloy thin-walled disk parts, there are small holes on the end surface of the workpiece that need to be processed, and the surface finish of the small hole diameter is required to be very high. If the traditional process of drilling first, then turning the drilled hole, and finally boring the turned aperture, the processing efficiency is low, the processing pass rate is low, the position of the aperture is poor, and the inner wall of the hole is easy to appear. A case of taper occurs. In addition, the above-mentioned processing technology cannot meet the needs of large-scale industrial production in terms of processing efficiency and tool cost. Contents of the invention [0003] The present invention is proposed to solve the problems existing in the prior art, and its purpose is to provide a p...
