Embodiment Construction

[0015] like figure 1 As shown, the invention discloses a tool edge sharpness tester. It includes PLC, input and output devices, transmission mechanism, special fixtures, special materials to be cut with sensors, and A / D converter, among which: the PLC is the core component, which is used to accept commands input from the input device to control the transmission The mechanism and the special fixture perform the shearing action, then accept the A / D converted signal from the sensor for processing, and output the test value through the output device.

[0016] The working principle of the device of the present invention is: the transmission mechanism is driven by a stepping motor controlled by PLC, so that the special fixture equipped with the tool to be tested moves up and down to complete the cutting process of the special material installed on the sensor. In the cutting of special materials, the sensor is subjected to the force of the cutting edge, and the sensor generates a st...

Abstract

The invention relates to a knife quality detection device, particularly relates to a knife edge sharpness tester. It includes a PLC, an input device, an output device, a transmission mechanism, a special fixture, a kind ofspecial-purpose material equipped with a sensor for being cut, an A / D converter, wherein: the PLC is the kernel component, which is used for receiving command inputted from the input device to control the transmission mechanism and the special fixture for carrying out the cutting movement, then for receiving the signal converted by the A / D from the sensor, then outputs the tested value from the output device. The device can display the needed value and the cutting-off force curve when the knife cuts off special-purpose material, the measure equipment is a reliable, has accurate data, can make magnitude evaluation of the knife edge sharpness, and is convenient to use. The special fixture is mounted for testing and evaluating the shearing force of scissor. Compared with original artificial subjective test and judgment, the obtained test result is more objective and accurate.

Description

technical field [0001] The invention relates to a tool quality inspection device, in particular to a tool edge sharpness tester. Background technique [0002] my country has a long history of cutting tool production, but the detection of the sharpness of the cutting edge is still in a rather backward state. Manual shearing is used to detect the sharpness of the cutting edge. There is no quantitative detection method to judge, and it cannot be guaranteed. Inspect the consistency and comparability of the cutting edge sharpness. Thereby seriously hindered the progress of the knife and scissors industry, especially for the knife and scissors industry products to enter the international high-end market is very difficult. The invention patent can accurately display the force value and cutting force curve when the cutting edge of the tool cuts special materials. Contents of the invention [0003] The purpose of the present invention is to provide a tool edge sharpness tester, wh...
