A sawing simulation test device and test method

Abstract

The invention relates to a saw cutting simulation testing method. The method comprises the steps that a toothed blade is installed on a blade holder; the relative position of the toothed blade and a workpiece is adjusted through a transmission mechanism, a connecting line of the tooth top of the toothed blade and a workpiece rotation center is parallel to the length direction of the toothed blade,the plane where the toothed blade is located is perpendicular to the axial direction of the workpiece, blade setting is conducted, and cutting simulation testing is ready to be conducted; after bladesetting is completed, constant feed rate simulation cutting testing or constant feed force simulation cutting testing is conducted as needed. Accordingly, a large number of testing materials can be saved, and the testing cost is reduced; a saw cutting simulation testing device is wide in application, people only need to make adaptive change on the blade holder, and then the device can be applicable to simulating testing of band saw blades of various specifications; the influence caused by the factors such as equal altitude and tooth amount error of the band saw blade manufacturing process onthe testing process is eliminated, abrasion resistance and tooth-shaped cutting force of single sawtooth are detected directly, and meanwhile data is stable.

Description

technical field [0001] The invention relates to the field of cutting tool monitoring equipment, in particular to a sawing simulation test device and a test method, in particular to a single-tooth sawing simulation test device and a test method. Background technique [0002] The band saw blade is a multi-edged tool, but it is different from traditional tools such as turning, milling and planing. The bimetallic band saw blade is a combination of high-speed steel with a tooth portion of 1-2 mm on a flexible spring steel base belt through laser, electron beam and other high-speed beam welding methods. The saw wheel drives the saw blade to rotate in a circular manner to complete the cutting of the material. Bimetallic saw blades are generally processed in discs, and their processing accuracy is affected by many factors such as raw materials and processing technology. At the same time, in the actual use process, there are many ways for the band saw blade to fail, such as broken b...

Problems solved by technology

[0004] The main shortcoming of existing test method is: 1) test period is long

If the saw blade is tested under standard working conditions, taking sawing 45 steel as an example, the test time for a single saw blade with a width of 27mm is about 100 hours, and when 5 saw blades are tested, the total test time is more than 500 hours, and the test cycle is very long; 2) High material cost

Taking the 45 steel sawing test as an example, the cost of No. 45 raw materials consumed by a single saw blade test is more than 2,000 yuan; 3) The data fluctuates greatly and the reliability is not high

The test process is affected by the impurities and hardness of the material to be cut, as well as the performance fluctuation of the saw blade itself, and the data fluctuates greatly.
