Description
Technical field
The modified model that the present invention relates to aluminium transfer mold atomizing sprayer vibration damper is met and discussed, and belongs to field of metal casting technology.
Background technique
Aluminium die casting is one of aluminium product processing method commonly used, when die-casting process, at first under die opening state, need spray releasing agent to cavity surface, with the good demoulding of product after the assurance die casting.Existing release agent spraying comprises artificial spraying and atomizing sprayer spraying, and artificial the spraying exists troublesome poeration, and flushing liquor becomes the raindrop shape, and wastage of material is big, and shortcoming such as inhomogeneous; Said atomizing sprayer spraying comprises that the atomizing sprayer main body connects the pipeline of water source, pressurized air and releasing agent, through single-chip microcomputer PC automatic control system; By pressure with water, aerosolization; Suck the die casting releasing agent then, the aqueous vapor of pressure atomization is mixed the die cavity spraying of back to mould with releasing agent, the releasing agent that mixes through atomizing sprays cavity surface with mist condition state and can not only reach good stripping result under pressure; Practice thrift simultaneously releasing agent raw material, reduction expense again.Said aluminium transfer mold atomizing sprayer comprises Aluminum press casting apparatus support fitting seat, is connected spraying chassis base and atomizing sprayer assembly on the support fitting seat, and the atomizing sprayer assembly connects injection spray pipe and powered support; Because the very big downward force that drives with cylinder in the atomizing sprayer assembly during spraying can produce vibration, so a shock mitigation system is arranged; Described shock mitigation system comprises that powered support connects long left and right arms and short left and right arms one, and the other end of long left and right arms and short left and right arms is connected on the spraying chassis base, on short left and right arms, meets and discusses; The bottom mounting shock absorber of spraying chassis base, described vibration damper comprises support, rack-mount absorber main body; Buffer bar is installed in the main body; The buffer bar head is installed percussive cap, mounting spring between percussive cap and main body, and said meeting and discussing on short left and right arms contacts with percussive cap.Meeting and discussing of existing technology is the cam of processing one with short left and right arms, and be as shown in Figure 3, when work; One of short left and right arms 8 is driven along with the powered support operation and around the rotatingshaft 4 curved motions that are installed on the die casting spraying chassis base 1 by cylinder, and it is very big to exert oneself in the promotion of cylinder, and cam 82 not only impacts greatly; And the curved percussive cap 75 that is impacting on vibration damper 7 buffer bars, what percussive cap received is the impact force that is scraping, therefore; The frictional force that the last plane of percussive cap receives is big, causes very quick-wearing, and makes buffer bar 73 crooked and rupture; Whole vibration damper is short working life, not only increases maintenance expenses, and in shutting down maintenance, influences working efficiency.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming that prior art exists; Provide a kind of percussive cap of vibration damper to avoid receiving scraping power; The power of reducing friction; Alleviate wearing and tearing, make buffer bar reduce bending deflection or fracture simultaneously, improve the modified model of the aluminium transfer mold atomizing sprayer vibration damper in vibration damper working life and meet and discuss.
The technological scheme that the modified model of aluminium transfer mold atomizing sprayer vibration damper of the present invention is met and discussed is: comprise Aluminum press casting apparatus support fitting seat, the support fitting seat connects spraying chassis base and atomizing sprayer assembly, and the atomizing sprayer assembly connects injection spray pipe and powered support; Powered support is driven by cylinder, and powered support links to each other with one that lacks left and right arms with long left and right arms, and the other end of long left and right arms and short left and right arms is connected on the spraying chassis base through rotatingshaft; Mounting shock absorber below the spraying chassis base; Described vibration damper comprises the body support, is installed in the absorber main body on the body support, and buffer bar is arranged in the absorber main body; The head of buffer bar connects percussive cap; Mounting spring between percussive cap and absorber main body is characterized in that on the described short left and right arms bearing being installed, and bearing contacts with the last plane of percussive cap.
The modified model that the invention discloses a kind of aluminium transfer mold atomizing sprayer vibration damper is met and discussed; Change the cam on the short left and right arms into bearing, of short left and right arms does upper and lower operation through powered support along with the atomizing sprayer assembly is driven by cylinder, and the other end of short left and right arms is installed on the spraying chassis base by rotatingshaft; So short left and right arms is made arcuate movement around rotatingshaft when work; The cam or the bearing that are connected on the short left and right arms also have frictional force when percussive cap on the vibration damper contacts except impact force, because cam is processed one with short left and right arms, frictional force is very big; Surface wear is serious on the percussive cap; Buffer bar receives bigger bending deflection power simultaneously, produces fracture damage, influences the working life of whole vibration damper.And after changing bearing into, bearing is run into percussive cap and is rotated, and impact force is constant, but frictional force is very small, and the plane almost there is not wearing and tearing on the percussive cap, and the suffered bending force of buffer bar is very light, in the working life of having improved vibration damper, has obtained result in unexpected positive.
The modified model of aluminium transfer mold atomizing sprayer vibration damper of the present invention is met and discussed, and saidly in short left and right arms, is shaped on bearing mounting hole, and Bearing Installation and has part to reach outside the mounting hole in mounting hole.In mounting hole, bearing is connected reliably with short left and right arms with Bearing Installation, and the both sides balance is stressed even.Said bearing comprises the bearing pin that is installed on the short left and right arms, and one of bearing pin has large washer and spring washer, and large washer and spring washer fix through screw.Bearing is fixed through bearing pin and short left and right arms, and easy for installation, there had large washer and spring washer that screw and bearing pin are tightened to be firm, and it is loosening to avoid bearing pin and screw to produce.
