Attachment plate for a hydrostatic piston machine and method of fabrication of said plate

摘要

#CMT# #/CMT# The method for the manufacture of connecting plates (2) of hydrostatic machines entails manufacturing an extruded profile (44), the cutting to length of the extruded profile into connecting plate blanks (45), and then carrying out finishing machining of the blanks. The extruded profile is manufactured through casting or pressing. The cutting to length may be carried out by sawing, laser cutting, water jet cutting or by a heat erosion process. #CMT# : #/CMT# An independent claim is included for a connecting plate of a hydrostatic machine and which is manufactured from an extruded profile. #CMT#USE : #/CMT# The method applies to the manufacture of connecting plates of hydrostatic machines and especially axial piston machines. #CMT#ADVANTAGE : #/CMT# A simple, flexible and inexpensive manufacturing method for a connecting plate is devised which reduces the cost of manufacture and the number of machining stages. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# One drawing shows an extruded profile with three cut-to-length connecting plate blanks to describe the manufacturing process, and the other drawing shows a connecting plate. 2 : connecting plate 16S : suction channel 16D : pressure channel 44 : extruded profile 45 : connecting plate blanks 46 : holes #CMT#METALLURGY : #/CMT# The extruded profile is made at least partially from aluminum, iron or copper, or from an alloy with at least one of these metals.
