Abstract
The invention discloses a band saw blade manufacturing method, which comprises the following steps: s1, carrying out tooth forming treatment on the steel strip, and machining one side of the steel strip into a required tooth shape; s2 carburizing the steel strip with the formed tooth part; s3, quenching and tempering the steel strip with the formed tooth part; s4, carrying out tooth part passivation treatment on the ground band saw blade to remove the burr of the tooth tip; s5, performing tooth separation on the passivated band saw blade to obtain the running-in-free band saw blade. The invention has the advantages of improving the production efficiency of the band saw blade, utilizing the existing production equipment of our company, improving the production efficiency and improving the processing precision.
Description
Technical Field
The invention relates to a band saw blade manufacturing method and a band saw blade, and belongs to the field of band saw blade manufacturing.
Background
The tooth part of the prior band saw blade is usually formed by a milling mode, and the roughness of the front cutter face of the band saw blade produced by the process is difficult to reach the level of the grinding mode. The tip burr is large. After milling, the tooth tip has obvious burrs, and the burrs of the tooth tip cannot be removed in the subsequent process.
Disclosure of Invention
The invention aims to provide a band saw blade manufacturing method, which can not only realize that the band saw blade directly enters a conventional sawing stage without running-in, save the low-efficiency running-in step, shorten the running-in time from the manufacturing of the band saw blade to the actual production, but also prolong the service life of the band saw blade under the same condition, utilize the existing production equipment of the company, improve the production efficiency and improve the processing precision.
In order to solve the problem, the manufacturing method of the band saw blade comprises the following specific processes: a method for manufacturing a band saw blade, comprising the steps of: s1, carrying out tooth forming treatment on the steel strip, and machining one side of the steel strip into a required tooth shape; s2 carburizing the steel strip with the formed tooth part; s3, quenching and tempering the steel strip with the formed tooth part; s4, carrying out tooth part passivation treatment on the ground band saw blade to remove the burr of the tooth tip; s5, performing tooth separation on the passivated band saw blade to obtain the running-in-free band saw blade.
Further, the steel strip is subjected to tooth forming treatment by milling, grinding, punching, laser cutting or wire cutting.
Further, the quenching and tempering treatment of the steel belt with the formed tooth part comprises a heat preservation stage and an oil cooling stage which are sequentially carried out, wherein the temperature of the heat preservation stage is between 700 and 900 ℃, and the heat preservation time is controlled to be 3-5 h; the heating temperature in the tempering treatment process is between 300 ℃ and 350 ℃. Obtaining a band saw blade after heat treatment; and grinding the front cutter face and the rear cutter face of the band saw blade after the heat treatment. The invention has the advantages of improving the production efficiency of the band saw blade, utilizing the existing production equipment of our company, improving the production efficiency and improving the processing precision.

Detailed Description
Example 1
A band saw blade manufacturing method comprises the following specific steps: a method of manufacturing a band saw blade, comprising the steps of: s1, carrying out tooth forming treatment on the steel strip, and machining one side of the steel strip into a required tooth shape; s2 carburizing the steel strip with the formed tooth part; s3, quenching and tempering the steel strip with the formed tooth part; s4, carrying out tooth part passivation treatment on the ground band saw blade to remove the burr of the tooth tip; s5, performing tooth separation on the passivated band saw blade to obtain the running-in-free band saw blade. The steel belt is subjected to tooth forming treatment by milling forming, grinding forming, punching and shearing forming, laser cutting or linear cutting. The quenching and tempering treatment of the steel strip formed by the tooth part comprises a heat preservation stage and an oil cooling stage which are sequentially carried out, wherein the temperature of the heat preservation stage is between 700 ℃ and 900 ℃, and the heat preservation time is controlled to be 3-5 h; the heating temperature in the tempering treatment process is between 300 ℃ and 350 ℃. Obtaining a band saw blade after heat treatment; and grinding the front cutter face and the rear cutter face of the band saw blade after the heat treatment. And polishing if surface defects exist after the quenching and tempering treatment. The deburring and polishing process adopts a multifunctional driving type deburring mechanism and a tempering and cooling device.
The foregoing examples are set forth to illustrate the present invention more clearly and are not to be construed as limiting the scope of the invention, which is defined in the appended claims to which the invention pertains, as modified in all equivalent forms, by those skilled in the art after reading the present invention.
Example 1 is the best mode.
