Abstract
The utility model relates to a timber crushing apparatus, concretely relates to timber is smashed and is used wear-resisting blade, including sword cutting edge and back of a knife blade face, the abrasionproof layer has been welded respectively to sword cutting edge and back of a knife blade face, the abrasionproof layer width at the back of a knife blade face is not more than 4mm, the abrasionproof layer width on the sword cutting edge is 7~10 mm. The abrasion-proof layer is welded on the blade face, so that the abrasion resistance can be improved, the integral strength of the blade can be improved, and the service life of the blade is prolonged. When the blade is repaired, the blade can be directly used repeatedly by welding for 11-15 months, and the blade can still be normally used after being repaired for at least 3 times.
Description
Technical Field
The utility model relates to a timber crushing apparatus, concretely relates to timber is smashed and is used wear-resisting blade.
Background
The wood crusher crushes various kinds of wood by the rotation of a knife roll, and a plurality of blades are arranged on the circumference of the knife roll. The blade is a slender piece, the high-pressure rolling cutting stress is large, the blade edge of the blade is seriously abraded, the service life is short, the blade is required to be replaced after about four months according to the working time of 10 hours a day, otherwise, the material is abraded to the roller surface of the knife roller. In this case, the crusher needs to be disassembled and then maintained and replaced, which greatly affects 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 blade, long service life can restore cyclic utilization. The utility model adopts the technical scheme as follows:
the wear-resistant blade for wood smashing comprises a blade edge face and a blade back face, wherein an anti-abrasion layer is welded on the blade edge face and the blade back face respectively, the width of the anti-abrasion layer on the blade back face is not more than 4mm, and the width of the anti-abrasion layer on the blade edge face is 7-10 mm.
The wear-resistant blade for wood smashing is characterized in that a plurality of welding points are respectively spot-welded on edges on two sides of the blade and the blade edge.
The wear-resistant layer and the welding points of the wear-resistant blade for crushing the wood are formed by welding HRC60 metal powder-cored welding wires and HRC90 hard alloy particles.
The utility model has the advantages that: the abrasion-proof layer is welded on the blade face, so that the abrasion resistance can be improved, the integral strength of the blade can be improved, and the service life of the blade is prolonged. When the blade is repaired, the blade can be directly used repeatedly by welding for 11-15 months, and the blade can still be normally used after being repaired for at least 3 times.
Drawings
Fig. 1 is a schematic front view of the present invention;
fig. 2 is a schematic back view of the present invention.
In the figure: 1 is the knife edge surface, 2 is the knife back surface.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The wear-resistant blade for wood smashing comprises a blade face 1 and a blade back face 2, wherein an anti-abrasion layer is welded on the blade face 1 and the blade back face 2 respectively, the width of the anti-abrasion layer on the blade back face 2 is not more than 4mm, and the width of the anti-abrasion layer on the blade face 1 is 7-10 mm. The width of the anti-abrasion layer of the knife back surface 2 is required to be small, so that impurities splashed to the knife back surface in the processes of large-area welding heat treatment and the like are prevented from affecting the flatness of the knife back surface, and if the flatness is changed, material scraps in a gap assembled between the knife back surface 2 and the knife roller enter to affect the matching strength.
The wear-resistant blade for wood smashing is characterized in that a plurality of welding points are respectively spot-welded on edges on two sides of the blade and the blade edge.
The wear-resistant layer and the welding points of the wear-resistant blade for crushing the wood are formed by welding HRC60 metal powder-cored welding wires and HRC90 hard alloy particles.
Claims (3)
