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
The present invention relates to be used for the cutter quality detection device, particularly a kind of tester for tartness degree of tool cutting edge.
Background technology
It is with a long history that China's cutter is produced; But the sharpness detection to cutting edge roundness still is in the state that quite falls behind; Adopt artificial shearing to detect the quality of tartness degree of tool cutting edge; The quantitative detection means of neither one is judged, can't guarantee to detect the consistance and the comparability of tartness degree of tool cutting edge.Cut the pace of progress of industry thereby seriously hindered cutter, the industry product is cut in special tool setting, and to get into international up-market difficult especially.Patent of the present invention is the power value in the time of demonstrating cutting edge roundness cut-out proprietary material exactly and cuts off force curve.
Summary of the invention
The object of the present invention is to provide a kind of tester for tartness degree of tool cutting edge; Mainly solve the artificial shearing of available technology adopting and come the existing problem of artificial subjective judgement tartness degree of tool cutting edge; It can not only obtain objective test result, and has improved testing efficiency.
For addressing the above problem, the present invention is achieved in that
A kind of tester for tartness degree of tool cutting edge is characterized in that: the quilt that it comprises Programmable Logic Controller (PLC), input, output unit, gear train, unit clamp, be provided with sensor is cut proprietary material, A/D converter, wherein:
This PLC is a core component, and the instruction control gear train and the unit clamp that are used to accept from input media is imported carry out shear action, accept then to handle from the signal through the A/D conversion of sensor, and through output unit output test value.
Described tester for tartness degree of tool cutting edge is characterized in that: this input media is a touch-screen.
Described tester for tartness degree of tool cutting edge is characterized in that: this output unit is touch-screen and printer.
Described tester for tartness degree of tool cutting edge is characterized in that: this gear train is the step motor drive by PLC control.
Described tester for tartness degree of tool cutting edge is characterized in that: the proprietary material that this quilt is cut is fixed on the material folding frame.
Described tester for tartness degree of tool cutting edge; It is characterized in that: cut the uniform tension in order of proprietary material in each the detection for making, when clamping, should lie in the proprietary material of being longer than the clamping frame width slightly on the clamping frame earlier, tighten the clamping frame pressing plate; An end fix tightly of proprietary material; The other end of proprietary material stretches out the weight that the clamping frame place hangs a constant weight, makes proprietary material tensioner smoothly, tightens another briquetting of clamping frame again.
By technique scheme, the invention has the beneficial effects as follows:
Apparatus of the present invention can show power value required when cutter cuts off proprietary material and cut off force curve, are a kind of tool good reliabilitys, and data are accurate, can make the evaluation of value to tartness degree of tool cutting edge, surveying instrument easy to use.It is installed the exclusive clamps prodigiosin shearing force of scissors is tested and estimated.Compare with original artificial subjective testing judgement, the test result of acquisition is more objective, accurate.
Description of drawings
Fig. 1 is the structural representation of apparatus of the present invention.
Embodiment
As shown in Figure 1, the invention discloses a kind of tester for tartness degree of tool cutting edge.The quilt that it comprises PLC, input, output unit, gear train, unit clamp, be provided with sensor is cut proprietary material, A/D converter; Wherein: this PLC is a core component; The instruction control gear train and the unit clamp that are used to accept from input media is imported carry out shear action; Accept then to handle from the signal through the A/D conversion of sensor, and through output unit output test value.
The principle of work of apparatus of the present invention is: gear train is by the step motor drive of PLC control, and the unit clamp that tested cutter is housed is moved up and down, and accomplishes being installed in the cutting process of the proprietary material on the sensor.Sensor receives the acting force of cutting edge roundness in the special cutting material; Sensor just produces strain signal; Through special-purpose A/D converter; Input PLC, PLC receives the treated coded data of this signal and on touch-screen, demonstrates the instant power value and the curve of shear history, and can be through printer prints output.
The course of work of apparatus of the present invention is: earlier the proprietary material of being cut (polyurethane film, in flat nankin, particular chemical paper pulp sheet etc.); Be fixed on the material folding frame, cut the uniform tension in order of proprietary material in each the detection, when clamping, should lie in the proprietary material of being longer than the clamping frame width slightly on the clamping frame earlier for making; Tighten the clamping frame pressing plate; An end fix tightly of proprietary material, the other end of proprietary material stretches out the weight that the clamping frame place hangs a constant weight, makes proprietary material tensioner smoothly; Tighten another briquetting of clamping frame again, the expanding force basically identical of proprietary material when guaranteeing each the test like this.Then be the zero setting of power valve system, use 1N, 3N, 5N, 10N, 20N, the standard test weight of 25N is single one by one to be placed on the sensor (material folding frame), demarcates displayed value on the screen, and the error that makes itself and standard test weight value is less than 1%.After the power valve system is demarcated and is finished; Be installed in tested cutter on the unit clamp; Start gear train, when proprietary material contacts on cutting edge roundness and the material folding frame (sensor begins stressed), promptly demonstrate cutting edge roundness on the screen to the real-time force value of being cut material; Until rupturing being cut material, power value at this moment is exactly the indicated value of tartness degree of tool cutting edge.
Being merely preferred embodiment of the present invention in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of claim of the present invention change and modification, all should be technological category of the present invention.
