Description
Technical field
The present invention relates to a kind of production methods of partition in Compressor Technology field more particularly to multicylinder compressor.
Background technique
Rotor type cold compressor because its high cooling efficiency, it is compact-sized, small in size, light-weight due to be widely used in household
Inside equal air conditioners.
Compression assembly is the pith in rotor type cold compressor, mainly includes cylinder, piston, slide plate, crankshaft, master
Bearing and supplementary bearing.In multicylinder compressor include at least two cylinders, each cylinder have compression chamber, two adjacent cylinders it
Between be equipped with partition, be formed with the through-hole of perforation so that crankshaft passes through on partition.
Currently, partition generally uses casting technique or powder metallurgical technique to be made.
It is solid blanks that casting technique, which usually melts cast iron to be cast in die for molding after liquid, then by thick
The technique of finished product needed for the multiple working procedures such as processing, finishing are realized.Powder metallurgy be usually using metal powder as raw material, or
Using the mixture of metal powder and non-metal powder as raw material, by shaping and being sintered the technique for realizing required finished product.
But casting technique and powder metallurgical technique, there are process complexity, processing efficiency is low, and at high cost, processing conditions is disliked
It is bad, it pollutes the environment and processing waste material is more, lead to the wasting of resources.
Summary of the invention
For the status of partition manufacture craft in above-mentioned multicylinder compressor, the present invention is intended to provide in a kind of multicylinder compressor
The production method of partition can simplify the manufacture craft of partition using this method, reduce cost of manufacture.
In order to achieve the above technical purposes, the present invention uses steel, is made in multicylinder compressor by the method for cutting
Partition, that is, the technical solution of the present invention is as follows:
The production method of partition in a kind of multicylinder compressor, compressor include at least two cylinders, and partition is located at adjacent
Between two cylinders, setting is used for the through-hole A that crankshaft passes through on partition；
It is characterized in that: making the partition by cutting technique using steel.
The steel are unlimited, including carbon steel and steel alloy etc..
The steel form is unlimited, preferably steel plate.
The settable structural unit with certain function on the partition, such as can be arranged on partition for being vented, pacifying
The through-hole B etc. of dress etc..When the structural unit is arranged on partition, can by cutting steel be required diaphragm structure after,
Further processing makes the structural unit；For certain structural units that can be obtained by cutting technique, can also cut
These structural units etc. are directly made in the process.
Compared with existing dummy plate method, the present invention has the advantage that
(1) present invention can be prepared by partition by cutting technique according to the shape and size of required partition using steel,
Compared with existing casting technique or powder metallurgical technique, manufacture craft is on the one hand enormously simplified, reduces processing cost,
And it is environment friendly and pollution-free, on the other hand with the development of cutting technique, producing efficiency and production essence can be taken into account using this method
Degree.It, can especially when cutting technique uses laser cutting parameter or high pressure jer cutting technique (also referred to as water knife)
Further increase producing efficiency and production precision.
Laser cutting belongs to one of method for hot cutting, is the high power density laser beam irradiation workpiece using line focus, makes
Illuminated material melts rapidly, vaporizes, ablation or reaches burning point, while melting by blowing down with the coaxial high-speed flow of light beam
Substance cuts open workpiece to realize.Since laser facula is small, energy density is high, cutting speed is fast, therefore laser cutting can
Obtain preferable cut quality: laser cutting notch is narrower, cutting surfaces it is bright and clean it is beautiful, workpiece deformation is small, cutting accuracy is high, cuts
The geometry of seam is good；And cutting efficiency is high.
High pressure jer cutting is the new process developed using water jet technique and High Speed Grinding, principle
It is: water is forced into the pressure of 200~400MPa, water is made to have huge pressure energy, send into the nozzle of aperture very little, is added
Abrasive material, water and abrasive material are sprayed after mixing with the high speed of twice velocity of sound, form the dissection to workpiece.The cutting method
The disposable cutting processing of arbitrary curve can be carried out to material, the heat that when cutting generates can be immediately by swiftly flowing water-jet
Stream is taken away, and does not generate harmful substance, and material does not need or be easy to secondary operation without fuel factor after cutting, safe and environment-friendly,
Fast speed, efficiency it is higher, it can be achieved that arbitrary curve cutting processing.
Therefore, preferably laser cutting or high pressure jer cutting makes the partition in the present invention.
(2) present invention is directly made using steel, since steel have good dimensional accuracy, intensity, hardness, just
Property and elasticity modulus, therefore can guarantee partition integral strength and hardness, while can guarantee to process the size of partition obtained
Precision has a good application prospect.
