Embodiment Construction

[0029] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0030] Such as figure 1 , figure 2 As shown, the load cell 1 is composed of a resistive strain gauge 10, a resistive strain gauge 11, a resistive strain gauge 12, and a resistive strain gauge 13. The specific manufacturing steps of the load cell 1 are as follows:

[0031] 1. Use sandpaper, acetone, absorbent cotton, and tweezers to clean the oxide layer, oil, dust, and rust spots on the surface of the column of the screw press;

[0032] 2. Paste the four resistive strain gauges on the flat surface of the press column with glue. The resistive strain gauge 8 and the resistive strain gauge 10 are parallel to the axial direction of the press column. The resistive strain gauge 9 and the resistive strain gauge The strain gauge 11 is perpendicular t...

Abstract

The invention belongs to the technical field of a pressure machine, and relates to a device and method for measuring of hitting force of a pressure machine in real time, and a manufacturing method of the device. The device comprises a force measuring sensor, an amplifier, a data acquisition card, a router and a pressure machine force measuring module, wherein the force measuring sensor is composed of a Wheatstone bridge which is formed in a manner that a resistance-type strain gauge is stuck to the surface of a vertical pillar of the pressure machine; the amplifier is connected with the force measuring sensor; the data acquisition card is connected with the amplifier; the router is connected with the data acquisition card; and the pressure machine force measuring module is connected with the router. After being calibrated by a ring specimen, the device disclosed by the invention is used for measuring the hitting force in real time so as to guide practical production, control production cost and improve production efficiency.

Description

technical field [0001] The invention relates to a device and method for measuring striking force, in particular to a device and method for real-time measuring the striking force of a press and a manufacturing method of the device. Background technique [0002] The press is a versatile press with an exquisite structure. With the characteristics of wide application and high production efficiency, the press can be widely used in cutting, punching, blanking, bending, riveting and forming processes. Processed into parts by applying intense pressure to a metal blank to cause the metal to plastically deform and fracture. [0003] For small-tonnage presses, commonly used impact force measurement methods include impulse method, acceleration method, and force sensor electrical measurement method. The electric measurement method of the load cell is a method of converting the non-electrical quantity to be measured into an electric quantity, and then measuring it. At present, the measu...
