Problems solved by technology
Due to the small number of loading points, the distribution of the actual loading load is actually uneven, which is far from the uniform load required for measurement, which directly affects the accuracy of the measurement and the accuracy of the measurement data.
[0004] The capacity generation point refers to the distance from the slider to the bottom dead center when the press reaches the nominal pressure. It is an important indicator of the press, but due to the lack of a load generating device close to the actual load, this indicator cannot be accurately measured

Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the embodiments of the accompanying drawings.
[0024] Such as figure 1 As shown, a uniformly distributed load generating device includes an oil cylinder integrated board 1 and a hydraulic control system 6 including various control valves.
[0025] The above-mentioned oil cylinder integrated board 1 is provided with three areas of left, middle and right, and the three areas of left, middle and right respectively contain oil cylinders arranged in multiple columns and rows.
[0026] The hydraulic control system 6 includes a first control valve 7 and a plurality of second control valves 4. The first control valve 7 controls the expansion and contraction of the piston rods 2 of the cylinders in the middle area of the cylinder manifold 1 arranged in rows. The second control valve 4 respectively controls the expansion and contraction of the piston rods 2 of each row of cylinders in the left...

The invention discloses a uniformly-distributed load generating device, which comprises an oil cylinder integrated board and a hydraulic control system, wherein the oil cylinder integrated board comprises a plurality of oil cylinders arranged in lines or columns; and for the oil cylinders in each line or each column, the extension and contraction of oil cylinder piston rods are controlled synchronously by using the same hydraulic control system. The uniformly-distributed load generating device has the advantages that: the oil cylinder integrated board consists of the oil cylinders in multiple columns and multiple lines, so that a corresponding force applying region of each oil cylinder is very small, the uniformity of load distribution is realized approximately, the magnitude of the uniformly-distributed load is adjustable, and the force applying region is controllable.
Description
technical field [0001] The invention relates to a uniformly distributed load generating device, in particular to a uniformly distributed load generating device used in static load deformation measurement and capacity generation point measurement of a closed press. Background technique [0002] The precision of the press is usually expressed by its static precision and rigidity, which have a great influence on the life of the die and the quality of the stamping parts. With the rapid development of modern stamping technology, various types of high-speed precision presses with different specifications, different structures and different types have appeared one after another to meet the special requirements of different products. Therefore, in order to ensure the overall performance of the press and various How to correctly and scientifically measure the static load deformation of the press is particularly important. [0003] When the current closed press standard performs stat...
