Description
Technical field
The present invention relates to shot-blasting machine field, more particularly to a kind of aluminium section bar shot-blasting machine ramming head.
Background technology
The jet chamber of the ramming head for the shot-blasting machine introduced from foreign countries is circular arc top plate and fan-shaped side plate group of the both sides with arc top
Fall the jet chamber of sector into a dome, this part, but state are produced with the high carbon and chromium antiwear cast iron alloy of hot investment casting
This part of interior wear resistant cast iron production carbon and chromium content on composition do not reach the requirement of import sample, and density is relatively low,
Lower hardness deformation is big after heat treatment, causes the percent defectives such as explosion high, and service life is short, and jet chamber sealing property compared with
Difference, after heat treatment difficulty of processing is big for part, in addition, the ramming head of external production, its jet chamber separates with bearing block, made
The dust that jet chamber flies out will not be directly entered bearing block, but so cause the supporting-point of impeller and bearing block farther out, rigidity
It is poor, will produce larger vibration after blade or impeller body wear and tear, therefore, the frequency of maintenance and maintenance cost of ramming head compared with
It is high.Therefore, a kind of it is proposed that aluminium section bar shot-blasting machine ramming head.
The content of the invention
The present invention ramming head main purpose be to provide a kind of aluminium section bar shot-blasting machine ramming head, the invention ramming head is simple in construction,
Bearing block is directly connected with gun housing adds ramming head rigidity, employ dry type hair felt-ring seal and using section's spiral forever get rid of sand launder and
The sealing structure that outside framework oil seal three is combined, substantially increases the sealing property of bearing block, although when spray gun is installed, bearing block center
Line tilts down about 20 degree, but it is unspent prevent sand dust from entering Bearing inner, ramming head is continuously used for a long time, and maintenance
Expense is low.Sour husky technique is instead of with sandblasting, aluminium consumption is reduced, 1 ‰ is down to by 9 ‰ -11 ‰, while effectively eliminating aluminium section bar
The mechanical line on surface, reduces production cost, improves Surface of profile quality, solves the process problem of fluorine in wastewater.Due to
The ramming head performance is good, can continuously be used for a long time, and maintenance cost is relatively low, so instead of import ramming head.It is domestic to be thrown with this
The aluminium section bar shot-blasting machine of head assembling has accounted for more than 90% in aluminium section bar shot-blasting machine, and this ramming head and with the assembling of this ramming head
Shot-blasting machine exported to Europe, the Middle East, Africa and Southeast Asian countries.
To achieve the above object, the present invention provides following technical scheme:A kind of ramming head of aluminium section bar shot-blasting machine, including:Rifle
Shell top cover, gun housing protecgulum, gun housing, trapezoidal plate, trapezoidal plate, the circumference top backplate and the circle of trapezoidal plate both sides being placed in above trapezoidal plate

Main shaft gos deep into jet chamber, front-end of spindle assembling impeller;
Gun housing protecgulum is equipped with sub-sand set, and sub-sand set is stretched into impeller bore, and sand flow is distributed to blade during to work, and impeller connects
The sub-sand pawl outer face connect is provided with sub-sand pawl helicla flute, and the end face constitutes non-contacting seal with bearing block drive end bearing bracket.Impeller revolves
When turning, sub-sand pawl helicla flute produces the air-flow that outwards gets rid of and sand dust is outwards thrown away, the sub-sand pawl helicla flute of sub-sand pawl outer face with
Felt seal ring in a circle sub-sand pawl felt groove, groove is additionally provided with interior end face to contact with bearing block drive end bearing bracket, forms dry type hair
Felt-ring seal.In bearing block drive end bearing bracket, outside framework oil seal is housed before the fore bearing of main shaft 16, third layer is carried out to main spindle front bearing
Protection.
It is preferred that, the other end of the bearing block is equipped with belt pulley.
It is preferred that, provided with middle oil sealing between the main shaft and fore bearing, Rear oil seal is provided between rear bearing and rear end cap.
It is preferred that, bearing block drive end bearing bracket makes of alloy die steel, stretches into the interstitial hole of trapezoidal plate, as jet chamber
In, the wearing piece of heart axle portion position is effectively protected bearing block end face;Impeller is mounted in the front-end of spindle of jet chamber, impeller
The sub-sand pawl end face and the end clearance of bearing block drive end bearing bracket that blade is higher by 10mm, impeller than impeller outer edge are 0.7-1.0mm.
Compared with prior art, beneficial effects of the present invention are as follows:
1st, this kind of aluminium section bar shot-blasting machine ramming head, is connected by using the circumference backplate side plate of spray chamber both sides by chase mortise formula
The circumference backplate top plate of part connection, so that part process and assemble is very simply, conveniently, and trapezoidal plate top plate and side plate are adopted
Enclosed with alloy tool steel plate, improve the hardness after heat treatment process, wearability and service life are added, due to impeller
Diameter is more than both sides impeller diameter when internal blade rotates, when spray gun is installed in lower room, due under bearing block and horizontal plane
Incline about 20 degree, shot and dust meeting nature are flowed into the gap of impeller rear end face and bearing block front end face, at this moment blade and sub-sand
Pawl end helicla flute can throw sand dust out.Blade gets rid of the shot of intracavitary, reduces the cylindrical abrasion of both sides impeller, while throwing
In the ball machine course of work, and it is connected in gun housing with bearing block by associated mode connector, so as to increase jet chamber and bearing
Imporosity between seat, adds the rigidity that ramming head housing is connected with bearing block,
2nd, the spiral groove seal and the internal wool felt set set using the sub-sand pawl end face outside being connected with impeller is close
Envelope, and the skeleton oil seal set in bearing block drive end bearing bracket, so employ dry type hair felt-ring seal and utilize section's spiral shell forever
The sealing structure that sand launder and outside framework oil seal three are combined is got rid of in rotation, effectively prevents sand dust from entering Bearing inner so that ramming head reaches company
It is continuous to use more than 18 months, freedom from repairs function.Motor directly drives belt pulley to be operated, and the inventive structure is simple, and increase is thrown
Head service life.
