The abrasion-proof layer is welded at each part of the hammer head, so that the abrasion resistance and the strength of the hammer head can be improved, the overhaul period is prolonged, and the improvement of the strength of the hammer sheet is favorable for the uniformity of the powder granularity.
Description
Technical Field
The utility model belongs to wood working equipment, concretely relates to pure wear-resisting hammer leaf of using of timber powder.
Background
The hammer type wood crusher crushes wood or straw and the like through a hammer, and specifically crushes the wood or the straw by colliding and rubbing the materials through hammer teeth by utilizing the relative motion of six groups of movable hammer assemblies which rotate at high speed inside and fixed gear rings around. Under the crushing working condition, the hammer sheet is a thin plate part which is easy to deform, wear and the like, so that the crushing granularity of the wood is uneven, and the subsequent processing is influenced. The hammer pieces of the crushers with different specifications are different from dozens of pieces to hundreds of pieces, and the frequent maintenance and replacement of the hammer pieces wastes time and labor, thereby affecting the production efficiency.
Disclosure of Invention
In order to solve the problem, the utility model provides a timber is smashed and is used wear-resisting hammer leaf, wear-resisting, the high non-deformable of intensity, the man-hour of work is long, is favorable to the high-efficient fast rhythm production of rubbing crusher. The utility model adopts the technical scheme as follows:
the wear-resistant hammer sheet for smashing wood comprises a hammer head and a hammer handle, wherein main hammer blades are arranged on two sides of the hammer head, auxiliary hammer blades are arranged on the side edges of the hammer head, wear-resistant layers are welded on the front and back surfaces of the two main hammer blades and the hammer head, and the wear-resistant layers on the surface of the hammer head are welded on the side close to the auxiliary hammer blades.
The wear-resistant hammer sheet for smashing the wood is characterized in that a plurality of anti-abrasion layers are welded at the junction of the hammer head and the hammer handle, and the width of a welding bead of each anti-abrasion layer is 4-6 mm.
The wear-resistant hammer sheet for smashing the wood is characterized in that the width of the wear-resistant layer on the hammer head surface is 10-20 mm.
The wear-resistant hammer sheet for smashing the wood is characterized in that a plurality of wear-resistant layers welded at the junction of the hammer head and the hammer handle are arranged in a crossed manner. The width of the hammer head is generally larger than that of the hammer handle, the change part of the width of the hammer head and the width of the hammer handle is easy to concentrate stress to cause the deformation or the tearing of the hammer head, and the cross welding of the anti-abrasion layers improves the connection strength between the hammer head and the hammer handle
The wear-resistant hammer sheet for crushing the wood comprises a wear-resistant layer, a wear-resistant layer and an auxiliary hammer blade, wherein the wear-resistant layer is formed by welding HRC60 metal powder-cored welding wires and HRC90 hard alloy particles, the thickness of the wear-resistant layer is not more than 5mm, and the HRC90 hard alloy particles are spot-welded on the auxiliary hammer blade.
The utility model has the advantages that: the abrasion-proof layer is welded at each part of the hammer head, so that the abrasion resistance and the strength of the hammer head can be improved, the overhaul period is prolonged, and the improvement of the strength of the hammer sheet is favorable for the uniformity of the powder granularity.
Drawings
Fig. 1 is a schematic front view of an embodiment of the present invention;
fig. 2 is a schematic top view of an embodiment of the present invention.
In the figure: 1 is a hammer head, 2 is a main hammer blade, 3 is an auxiliary hammer blade, and 4 is a hammer handle.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The wear-resistant hammer sheet for smashing wood comprises a hammer head 1 and a hammer handle 4, wherein main hammer blades 2 are arranged on two sides of the hammer head 1, auxiliary hammer blades 3 are arranged on the side edges of the two main hammer blades 2, the front side and the rear side of the hammer head 1 are respectively welded with an anti-abrasion layer, and the anti-abrasion layer on the surface of the hammer head 1 is welded on the side close to the auxiliary hammer blades 3.
The wear-resistant hammer sheet for smashing wood is characterized in that a plurality of anti-abrasion layers are welded at the junction of the hammer head 1 and the hammer handle 4, and the width of a welding bead of each anti-abrasion layer is 4-6 mm.
The wear-resistant hammer sheet for smashing the wood is characterized in that the width of the wear-resistant layer on the 1 surface of the hammer head is 10-20 mm. Although theoretically, the wider the wear-resistant layer is, the better the strength and wear resistance are, in actual repair, it is found that the wear of the wear-resistant layer which is too wide in the second repair is not uniform, and the weld bead is uneven when the weld is re-welded. The wear-resistant layer is controlled within a reasonable width range, so that uniform wear on the hammer head 1 can be guaranteed, and subsequent repeated repair work is facilitated.
The wear-resistant hammer sheet for crushing the wood is characterized in that a plurality of wear-resistant layers welded at the junction of the hammer head 1 and the hammer handle 4 are arranged in a crossed manner. The width of the hammer head 1 is generally larger than that of the hammer handle, the change part of the width of the hammer head 1 and the width of the hammer handle is easy to concentrate stress to cause the deformation or the tearing of the hammer head 1, and the cross welding anti-abrasion layer improves the connection strength between the hammer head 1 and the hammer handle
The wear-resistant hammer sheet for crushing the wood comprises a wear-resistant layer, wherein the wear-resistant layer is formed by welding HRC60 metal powder-cored welding wires and HRC90 hard alloy particles, the thickness of the wear-resistant layer is not more than 5mm, and the HRC90 hard alloy particles are spot-welded on the auxiliary hammer blade 3. In actual welding operation, because 1 two sides of tup have all welded the abrasionproof layer, the welding bead that can not avoid can overflow on vice hammer sword 3 a little, and the remaining space of vice hammer sword 3 is limited can't weld one welding layer again, and the technical staff further promotes the intensity and the wearability of hammer leaf on the whole in limited space midpoint welding alloy granule.
