Abstract
The invention belongs to the technical field of machining methods and particularly relates to a high-temperature blade machining method. The method mainly solves the problems that an existing machining device and method are low in grinding efficiency, quick in grinding wheel loss and high in machining cost. The high-temperature blade machining method includes the following steps that firstly, a blade blank to be machined is fixed to a blade tool, then the blade tool is fixed to a blade tool fixing frame, size parameters of a blade semi-finished product are set on a linear cutting machine tool according to the size of the formed blade, then the linear cutting machine tool is started, and an electrode wire conducts electric spark to machine the blade blank to be machined into the blade semi-finished product; secondly, the blade semi-finished product and the blade tool are taken down together, and a next blade is prepared for machining; thirdly, the blade semi-finished product is fixed to a blade tool base, a crawling grinding machine is started, a work grinding wheel starts to rotate, and a blade tool base fixing frame on the crawling grinding machine starts to conduct crawling machining on the blade semi-finished product into a blade finished product.
Description
Technical field
The invention belongs to processing method technical field, the processing method being specifically related to a kind of high temperature blade.
Background technology
High temperature blade processing conventional at present, is utilize the forming grinding wheel in wriggling grinding machine directly casting blank grinding-shaping.In the course of processing, forming grinding wheel will to the repeated multiple times grinding of foundry goods blank, and each grinding all can make abrasion of grinding wheel, and tradition wriggling grinding machine is equipped with the steel wheel that cost is high, ceaselessly emery wheel is carried out profile correction.Once, vacating space of will raising one's head allows operative employee that workpiece to be measured to the every grinding of emery wheel.Emery wheel, in grinding, comes back, goes the space motion that steel wheel place is revised that the required precision of lathe is high, and in order to accomplish automatically, also have to be equipped with the digital control system of complexity so that equipment cost is expensive, and working (machining) efficiency is extremely low.
Summary of the invention
Present invention is generally directed to current process equipment and method exists the problem that grinding efficiency is low, emery wheel loss is too fast and processing cost is high, it is provided that the processing method of a kind of high temperature blade.
The present invention solves the problems referred to above and the technical scheme taked is:
The processing method of a kind of high temperature blade comprises the following steps:
(1), blade blank to be processed is fixed on blade frock, again blade frock is fixed on blade frock fixed mount, according to formed blades size cutting on line lathe sets blade semi-finished dimensions parameter, blade semi-finished dimensions parameter 0.20mm less of formed blades dimensional parameters, being then turned on wire cutting machine tool to start working, blade blank to be processed is carried out spark machined and becomes blade semi-finished product by wire electrode；
(2), after linear cutting equipment group machines, related for blade semi-finished product blade frock is taken off together, and to linear cutting equipment group again blade blank, prepares to process next part；
(3), taking off the related blade frock entirety of blade semi-finished product, be fixed on blade frock base, and open wriggling grinding machine, work emery wheel starts to rotate, and the blade frock base fixed mount on wriggling grinding machine starts wriggling and is processed into blade finished product；
The equipment wherein used is formed by by linear cutting equipment group, wriggling mill equipment group, blade frock and work platforms, described linear cutting equipment group is made up of wire cutting machine tool, blade frock fixed mount and wire electrode, wire cutting machine tool is arranged on the upper left side of work platforms, blade frock fixed mount is arranged on the workbench of wire cutting machine tool, and wire electrode is arranged in the wire feeder of wire cutting machine tool and carries out spark machined；
Described wriggling mill equipment group is made up of grinding machine of wriggling, work emery wheel, blade frock base fixed mount and blade frock base, wherein wriggling grinding machine is arranged on the upper right side of work platforms, work emery wheel is installed on the main shaft of wriggling grinding machine, the workbench of blade frock base fixed mount and wriggling grinding machine fixes, blade frock is arranged on blade frock base and can carry out grinding, and blade frock base and blade frock fixed mount are on same datum line.
The present invention adopts technique scheme, first with wire electrode, blade blank to be processed is carried out spark machined molding, and the processing of high temperature blade is the spark machined without direct mechanical contact by wire electrode, and efficiency is high, a cutter, and does not have tool wear.Simultaneously because it is same plane with the fixed reference grinding the blade frock base adding man-hour of wriggling that cutting on line adds the blade frock fixed mount 3 in man-hour, add the size differing only by 0.2mm between blade semi-finished product and the finished product of linear cutter, allowance is minimum, adopt same datum level, can be accurately positioned within the scope of 0.2mm, so work emery wheel can adopt the grinding of extremely abrasive skive to put in place, processing dimension is accurate, and profile is very attractive in appearance.Relative to the allowance of 0.15mm, the service life of skive is extremely long.When the emery wheel size that works needs to be modified, adopt standby emery wheel to carry out grinding so that when repairing emery wheel, not affect normal production, comparatively speaking, be also greatly improved production efficiency so simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Embodiment 1
