Description

Technical Field

[0001] The invention belongs to the field of saw blade production inspection, and in particular relates to a saw blade quality inspection method. Background Art

[0002] A saw blade is a tool used to cut materials, usually wood, metal and other materials. Saw blades can have different shapes and sizes to suit different cutting needs. Depending on the use requirements, the saw blade has different specifications for the pitch and tooth shape of the saw blade.

[0003] When in use, the saw blade will repeatedly rub against the object to be cut. In addition to causing wear on the saw teeth, the repeated friction will also cause the saw teeth to be subjected to lateral force. At this time, if the quality of the saw teeth is unqualified, the lateral force may cause the saw teeth to break. Therefore, the quality inspection of the saw blade teeth is also part of the saw blade quality inspection. However, there is currently no method in the prior art to detect whether the saw teeth are subjected to lateral force. Summary of the invention

[0004] The main purpose of the present invention is to provide a saw blade quality inspection method for detecting whether the saw teeth of the saw blade are qualified.

[0005] To achieve the above purpose, the present invention provides a saw blade quality inspection method, which includes step S1: taking out the saw blade to be inspected, and processing a plurality of notches on the edge of the saw teeth of the saw blade to be inspected; step S2: fixing the saw blade to be inspected on a testing table, on which a vertically arranged metal rod is provided; step S3: moving the metal rod into a notch on the saw blade to be inspected; step S4: moving the metal rod in the direction of the saw tooth where the notch is located by a driving device; the driving device is connected to the upper and lower ends of the metal rod; step S5: according to the position of the notch, increasing the driving force of the driving device to drive the metal rod to a force threshold corresponding to the position of the notch; step S6: determining whether the quality of the saw blade to be inspected is qualified according to the state of the saw teeth.

[0006] The saw blade quality inspection method provided by the present invention comprises a plurality of notched grooves formed on the saw blade, wherein the main purpose of the notched grooves is to facilitate the insertion of a metal rod, thereby applying a lateral force to the saw teeth through the metal rod, thereby simulating the force applied to the saw blade during operation. Through the setting of the notched grooves, the metal rod is not easy to slip off, and the force direction of the saw teeth is more accurate. If the saw teeth are not broken when the force applied by the metal rod reaches a threshold, it means that the lateral force that the saw teeth can withstand meets the requirements, and the saw blade is qualified. Through this scheme, the quality assurance of the saw blade teeth after being subjected to lateral force is achieved.

[0007] As a further preferred technical solution of the above technical solution, the step S6 specifically includes: if the saw teeth are broken, determining that the saw blade to be tested is unqualified; if the saw teeth are not broken, determining that the saw blade to be tested is qualified.

[0008] As a further preferred technical solution of the above technical solution, after step S6, it further includes: step S7: if the saw blade to be tested is determined to be qualified in step S6, the metal rod is moved to a new notch on the saw blade to be tested and steps S4 to S6 are repeated. The force required for the breakage at each position of the saw tooth is different. By repeatedly testing the force applied in the notch at different positions, the qualified rate of the saw blade can be judged more accurately.

[0009] As a further preferred technical solution of the above technical solution, the force threshold in step S5 is determined according to the sawtooth shape of the saw blade to be detected, the material of the saw blade to be detected, and the position of the notch groove.

[0010] As a further preferred technical solution of the above technical solution, the material hardness of the metal rod is greater than the material strength of the saw blade to be detected. The metal rod has a greater hardness, thereby ensuring that the metal rod does not break when force is applied. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0015] See attached figure Figure 1 , Figure 1 Schematic diagram of a saw blade quality inspection method provided by the present invention. Figure 1 As shown, a saw blade quality inspection method provided by the present invention comprises:

[0016] Step S1: taking out a saw blade to be tested, and processing a plurality of notches on the edge of the saw teeth of the saw blade to be tested;

[0017] like Figure 2 The figure shows a schematic diagram of the saw teeth of the saw blade to be tested after the notch grooves are processed, wherein reference numeral 1 is the saw tooth, and reference numeral 2 is the notch groove. The processing of the notch groove can position and fix the saw blade on the corresponding workbench, and then use a tool to press down from above the saw blade to cut out a number of notch grooves. Since the saw blade is positioned and fixed on the workbench, the position of the notch groove finally processed on the saw tooth is relatively fixed, which is convenient for the accuracy of subsequent detection.

[0018] Step S2: fixing the saw blade to be tested on a testing platform, wherein a vertically arranged metal rod is arranged on the testing platform;

[0019] Step S3: moving the metal rod into a notch groove on the saw blade to be tested;

[0020] like Figure 3 As shown, when the metal rod moves into a notch groove, subsequent detection steps can be performed, and reference numeral 3 represents the metal rod.

[0021] Step S4: moving the metal rod toward the sawtooth direction where the notch groove is located by a driving device; the driving device is connected to the upper and lower ends of the metal rod;

[0022] Step S5: according to the position of the notch, increasing the driving force of the driving device driving the metal rod to a force threshold corresponding to the position of the notch;

[0023] Step S6: Determine whether the quality of the saw blade to be inspected is qualified according to the state of the saw teeth.

[0024] The saw blade quality inspection method provided by the present invention comprises a plurality of notched grooves formed on the saw blade, wherein the main purpose of the notched grooves is to facilitate the insertion of a metal rod, thereby applying a lateral force to the saw teeth through the metal rod, thereby simulating the force applied to the saw blade during operation. Through the setting of the notched grooves, the metal rod is not easy to slip off, and the force direction of the saw teeth is more accurate. If the saw teeth are not broken when the force applied by the metal rod reaches a threshold, it means that the lateral force that the saw teeth can withstand meets the requirements, and the saw blade is qualified. Through this scheme, the quality assurance of the saw blade teeth after being subjected to lateral force is achieved.

[0025] The movement and force of the above-mentioned metal rod can be achieved through existing driving technology and can be set according to actual needs.

[0026] As a further preferred technical solution of the above technical solution, the step S6 specifically includes: if the saw teeth are broken, determining that the saw blade to be tested is unqualified; if the saw teeth are not broken, determining that the saw blade to be tested is qualified.

[0027] As a further preferred technical solution of the above technical solution, after step S6, it further includes: step S7: if the saw blade to be tested is determined to be qualified in step S6, the metal rod is moved to a new notch on the saw blade to be tested and steps S4 to S6 are repeated. The force required for the breakage at each position of the saw tooth is different. By repeatedly testing the force applied in the notch at different positions, the qualified rate of the saw blade can be judged more accurately.

[0028] As a further preferred technical solution of the above technical solution, the force threshold in step S5 is determined according to the sawtooth shape of the saw blade to be detected, the material of the saw blade to be detected, and the position of the notch groove.

[0029] Specifically, depending on the tooth shape of the sawtooth and the position of the notch groove, if the thickness and width of the sawtooth in the lateral direction of the notch groove are larger, then the force threshold required on the notch groove will also be larger; if the material strength of the detection saw blade is greater, then the force threshold required on the notch groove will also be larger.

[0030] Since the processing position of the notch groove is relatively fixed for the sawtooth in step S1, the force threshold corresponding to each notch groove is also determined in advance, so the detection efficiency is high.

[0031] As a further preferred technical solution of the above technical solution, the material hardness of the metal rod is greater than the material strength of the saw blade to be detected. The metal rod has a greater hardness, thereby ensuring that the metal rod does not break when force is applied.

[0032] It is worth mentioning that for those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
