Description
Technical field
The invention belongs to hammer mills production technical fields, and in particular to a kind of manufacturing method of pulverizer hammer leaf.
Background technique
One end of the sheet that its hammer leaf of hammer crusher in the prior art is rectangle, the hammer leaf is equipped with pin hole, uses pin
Rod, screw etc. are connected with rotor, and the other end of hammer leaf is crushed work area, and the manufacture material in crushed work area is usually by common
Steel is as parent, and near upper and lower two angles in workspace and front edge then uses the wear-resistant material hardfacings such as tungsten carbide to form, table
Comentation hardening processing is made in face, the hammer leaf of the existing important crushed work component as pulverizer, and it is low to be primarily present crush efficiency,
The problems such as service life is short；Therefore it provides the pulverizer hammer leaf of a kind of wearability that hammer leaf can be improved and service life
Manufacturing method is very important.
Summary of the invention
The purpose of the invention is to overcome the deficiencies in the prior art, and provide a kind of wearability that hammer leaf can be improved and
The manufacturing method of the pulverizer hammer leaf of service life.
The object of the present invention is achieved like this: a kind of manufacturing method of pulverizer hammer leaf, it the following steps are included:
Step 1, it processes hammer leaf parent: hammer leaf parent, one end of the hammer leaf parent is processed using one time punching molded technique
It is provided with pin shaft hole, the other end of the hammer leaf parent is strike end；
Step 2, it is fixedly clamped: multiple hammer leaf parents is arranged successively neatly, and it is clamped simultaneously using dedicated fixture
It is fixed；
Step 3, a surfacing: adjustment by the hammer leaf parent of clamp makes its side upward, and with tungsten carbide filler rod its this
It is hit on side and carries out surfacing at the position at end, then whole overturning is carried out to by the hammer leaf parent of clamp, so that hammer leaf
It upward, and is hit on its side with tungsten carbide filler rod and to carry out surfacing at the position at end in the another side of parent, wherein every spray
A side is soldered to be both needed to separate using specific purpose tool between the adjacent hammer leaf parent on the side；
Step 4, secondary surfacing: whole overturning is carried out by the hammer leaf parent of clamp in step 3, repeats the mistake in step 3
Journey successively carries out secondary surfacing to two sides at hammer leaf parent strike end；
Step 5, surfacing three times: whole overturning is carried out by the hammer leaf parent of clamp in step 4, it is made to hit the top at end
Up, and with tungsten carbide filler rod surfacing is carried out on its top end face, then using specific purpose tool to the phase on the top end face
It is separated between adjacent hammer leaf parent；
Step 6, it separates: unclamping the fixture for clamping hammer leaf parent, successively separated above-mentioned multiple hammer leaf parents using specific purpose tool
It comes；
Step 7, it is heat-treated: comentation hardening processing is carried out to entire hammer leaf parent.
The hammer leaf parent uses P770 material.
Angle in the step 1 between the side at strike end and the side of hammer leaf parent of hammer leaf parent is not less than
180 degree.
The thickness of tungsten carbide of the surfacing on hammer leaf parent is female not less than hammer leaf in the step 3, step 4 and step 5
The thickness of body.
In the step 7, one end between adjacent two hammer leaves parent close to pin shaft hole is equipped with backing plate, the backing plate
For round or rectangular configuration.
Beneficial effects of the present invention: the hammer leaf parent in the present invention is one time punching molded using P770 material, later will be more
A hammer leaf parent marshalling is simultaneously fixedly clamped, and then carries out at surfacing twice to the two sides at hammer leaf parent strike end respectively
Reason carries out a surfacing processing to the top end face at hammer leaf parent strike end later, and can adopt behind the complete side of surfacing every time
It is separated with specific purpose tool between the adjacent hammer leaf parent on the side, it is female from hammer leaf with the tungsten carbide for preventing surfacing from completing
It is removed on body, hammer leaf parent hits the two sides at end by surfacing superposition process twice, can effectively improve it and hits the resistance to of end
Performance is ground, comentation hardening processing finally is carried out to entire hammer leaf parent, to improve the hardness of hammer leaf parent, comentation hardening processing
In the process, iron chair is installed close to one end of pin shaft hole between adjacent two hammer leaves parent, to prevent due to around pin shaft hole
Hardness is excessive and is broken；Total, the present invention has the advantages that the wearability that hammer leaf can be improved and service life.
