Embodiment 1

[0046] In the production process of inserting steel blade, the inventor finds that common slotting welding method has very big defective, traces it to its cause: traditional inserting steel blade (referring to figure 1 ) has a certain shape error (flatness) between the surface of the blade base and the bottom surface of the inlaid steel, resulting in no welding consumables on the joint surface, which in turn causes virtual, missing, or empty welding between the blade base and the inlaid steel. This causes very big economic loss and time loss to the steel insert blade manufacturer. In order to solve this problem, the inventor made an innovative improvement and provided a steel insert blade, which includes a blade base 1 and an alloy blade 4, and a welding surface 2 is arranged between the blade base 1 and the alloy blade 4 , the welding surface 2 is processed with a lattice structure. The lattice structure increases the surface roughness of the welding surface, indirectly incr...

Embodiment 2

[0048] to combine figure 2 , The steel-inserted blade of this embodiment has a lattice structure formed by two groups of lines intersecting each other, and a single group of lines is composed of a plurality of parallel straight lines. This form of lattice structure is completed by scraping by a fitter, or is processed by knurling, which can also increase the surface roughness of the welding surface, increase the solder stored on the joint surface of the blade base 1 and the alloy blade 4, and increase the welding material on the welding surface. The attachment area increases the bonding strength between the steel (tungsten steel / alloy) and the substrate.

Embodiment 3

[0050] to combine image 3 , the steel-inserted blade of this embodiment, its lattice structure is formed by two groups of lines intersecting each other, and a single group of lines is composed of a plurality of equally spaced circular arc lines.

[0051] It is worth noting that the lattice structure in the form described in Example 2 is completed by scraping by a fitter, or is formed by knurling. Although it has the basic effect of welding the steel insert blade that this patent wants to achieve, it is scraped by a fitter, or The use of knurling processing has the disadvantages of high labor intensity, slow processing speed, and the need to be processed by a CNC machining center with a complex structure. The large investment in equipment leads to high processing costs, which is not conducive to popularization.

[0052] In view of the above problems, this embodiment provides an arc-shaped lattice structure, which forms a closed lattice pattern by intersecting the return patter...

Abstract

The invention discloses a steel-inlaid blade and a welding surface processing method and a preparation method thereof, and belongs to the technical field of preparation of steel-inlaid blades. A welding face is arranged between a blade base body and an alloy blade, a lattice structure is machined on the welding face, the closed lattice is formed by intersecting milling machine tool return lines and cutting tool lines on the welding face, and the size and depth of lattice are controlled by adjusting the rotating speed of a tool. According to the steel-inlaid blade, the problem that a steel-inlaid blade is prone to crazing, fracturing and pseudo soldering is well solved, the quality of the steel-inlaid blade product is improved, and the service life of the steel-inlaid blade product is prolonged.

Description

technical field [0001] The invention relates to the technical field of preparation of steel-inserted blades, and more specifically relates to a steel-inserted blade, its welding surface processing method and preparation method. Background technique [0002] Industrial blades, as the name suggests, are blades used in industry and also the teeth of industrial machinery. With the advancement of science and technology, advanced machinery has higher and higher requirements for industrial blades, the speed of the machine is getting faster and faster, and the production efficiency and output are also increasing. The requirements for wear resistance and sharpness of industrial blades are more stringent, and it is difficult for industrial blades of ordinary materials to maintain high-intensity working time and working environment. [0003] In order to reduce production costs, or limited by blade materials, enterprises will use steel-inlaid industrial blades. The steel-inserted blad...
