Abstract
The invention relates to a production method of a steel blade which is arranged on a counter rotating axial main fan and is used in a coal mine containing explosive gas. The production method is characterized in that a welding hole used for plug welding is respectively arranged on an upper blade and a lower blade, the upper blade and the lower blade are connected with a blade stalk by welding the welding holes, one blade is connected with the periphery of the blade stalk through welding, and the edge of the upper blade is connected with the edge of the lower blade through welding. The invention has the advantages of long service life, safety, reliability and difficult damage and abscission, can better ensure to be used in a special environment of a mine and ensure normal running of the production.
Description
Technical field
The present invention relates to the production method of the steel blade on a kind of opposite-rotary axial flow type main fan impeller that in containing the colliery of explosive gas atmosphere, uses.
Background technique
In the prior art, used is the cast aluminium blade more, and it uses in the particular surroundings of mine, perishable damage, and working life is short.Another kind is a steel blade, and the steel blade normally adopts the wing blade double-layer hollow blade that is connected into by upper blade and lower blade.Being connected between upper blade, lower blade and the petiole generally is the mode that adopts rivet.The steel blade of this pattern may produce loosing of rivet, to such an extent as to the situation of leaf abscission is arranged, this brings totally unfavorable influence for the safe handling of main fan and the safety in production in colliery.
Summary of the invention
Purpose of the present invention will provide a kind of production method that can reach safe handling, not fragile, the steel blade that comes off exactly.Technical solution of the present invention is such: a kind of production method of opposite-rotary axial flow type main fan steel blade, steel blade is connected to form by upper blade, lower blade and petiole, it is characterized in that all having on upper blade, the lower blade welding hole that is used for plug welding, upper blade, lower blade are connected with petiole by the welding to welding hole, a blade and petiole periphery are arranged by being welded to connect, the edge of upper blade and lower blade is by being welded to connect.Use the invention has the beneficial effects as follows: working life is longer, and is not safe and reliable, fragile, come off, and can guarantee preferably to use in the mine particular surroundings, guarantees the normal operation of producing.
Description of drawings
Accompanying drawing 1 is the generalized section of steel blade.
Embodiment
In Fig. 1, all have the welding hole 4 that is used for plug welding on upper blade 1 and the lower blade 5, petiole 3 is connected between upper blade 1 and the lower blade 5.When making steel blade, the junction with around the petiole 3 with lower blade 5 welds with the fillet welding mode earlier, and welding hole 4 usefulness plug welding modes and the petiole 3 with lower blade 5 welds again.Then the junction of upper blade 1 with lower blade 5 front and rear edges welded, again 4 usefulness plug welding modes of the welding hole on the upper blade 1 and petiole 3 are welded.At last vane tip and root are sealed.Welding hole 4 on upper blade 1 and the lower blade 5 can be one, also can be a plurality of.
Embodiment 2
In Fig. 1, all have the welding hole 4 that is used for plug welding on upper blade 1 and the lower blade 5, petiole 3 is connected between upper blade 1 and the lower blade 5.Earlier upper blade 1 and petiole 3 junction are all around welded with the fillet welding mode, welding hole 4 usefulness plug welding modes and petiole 3 with upper blade 1 welds again, the junction of upper blade 1 with lower blade 5 front and rear edges welded, and welding hole 4 usefulness plug welding modes and the petiole 3 with lower blade 5 welds again.At last vane tip and root are sealed.This welding manner has avoided blade to take place from the situation that petiole comes off.Brought into play important function for the safety reliability that improves main fan.
